The resin sand sand mixer

Resin sand sand mixer is to point to: mixing resin sand for foundry enterprises, a continuous operation of the core sand sand mixing machine, the machine is made of continuous mixing liquid curing agent and liquid resin or self-hardening sand core making use of resin sand mixer. Resin sand sand mixer can be divided into: arms resin sand sand mixer and single arm resin sand sand mixer, in terms of the current domestic usage, resin sand sand mixer is generally refers to the arms of resin sand mixer, its characteristic is may consist of secondary free rotary stirring cage, the first level for conveying stirred cage, conveying the original sand; 2 high-speed sand stirring cage, the sand. Liquid resin and curing agent are in the second basket injection, injection curing agent, first time lag a spray into the resin.

The resin sand sand mixer features:

Resin sand sand mixer is a reference to the similar foreign advanced equipment, the advantages of optimized design, and after a lot of improvement, the assessment of the long-term production and development of new products, mixing is the ideal equipment of resin sand and sodium silicate sand, it has the following advantages:

(1) binder supply system adopts the advanced imported machinery curing agent and the diaphragm metering pump gear pump conveying resin, flow can be adjusted. Even with a viscosity fluctuation also can ensure the accuracy of the binder quantitative plus or minus 2.0% or less.

(2) the sand mixing evenly, effectively ensure the quality of molding (core) and molding rate.

(3) short mixing time, sand, backfilling losses small.

(4) down the back material clean.

(5) has a full open sand stirring cage wall, easy to stir the cage wall and blade cleaning and adjustment of the blade.

(6) operation and maintenance is convenient.

(7) electric control system adopts programmable controller, and set up a good work display restricts the protection and security, reliable operation and convenient for operation and maintenance.

(8) sand mixer inlet configuration of old and new sand ratio regulator, can accurately control the amount of sand old sand and its proportion, and can according to the advance in the process of sand proportion of tuned five to choose and change.

(9) arms turning operation with large coverage area.

(10) according to user requirements can be mounted to a set of auxiliary pump, as well as different types of resin or the same type of resin of different mixing amount on sand, so that the sand is more economic.

Resin sand sand mixer USES:

The sand mixing machine can be accurate quantitative add new sand, reclaimed sand and the binder with continuous mixing coagulation resin sand, and can be carried out within the 45 ㎡ area model, core operations.

Resin sand sand mixing machine installation

Figure 1, according to the related model equipment foundation construction foundation, should go line pole and base built into the base under the car. Installed at the base of the center of the flange relative sand bucket out of the center of the flange of tolerance of 3 mm or less; On the plane the levelness tolerances 2 mm or less.

2, connection and installation base sand mixing machine base, adjustment of three screw nail guarantee sand mixer base plane levelness tolerances on 0.20/1000 or less, and padded with wedge iron and tighten bolts connection.

3, a connection, secondary stirring cage and base, allow only when lifting lug stirred cage.

4, install proportion regulator.

5, the connecting gas circuit system, electrical system, binder system.

Resin sand sand mixer debugging

1, check the

(1) secondary stirring cage with adjustable blade Angle and clearance should conform to the requirements of the blade adjustment. Such as attached figure 5, 6, and 7.

(2) gas path system without leakage, pressure as to meet the requirements of technical specification.

(3) binder system without leakage, no bubbles in the piping system.

(4) stirring cage shaft and binder pump to consistent with corresponding to sign.

(5) arms flexible rotation, smooth.

Resin sand sand mixing machine maintenance

1, regular cleaning,

< 1 > clean secondary sand stirring cage shaft, blade, crust on the lining board, per shift.

< 2 > clean up the mesh of resin and curing agent pump into the liquid, water, once a month.

< 3 > clean water filter cartridge and reversing valve silencer, with four carbon oxide after cleaning, rinse and compressed air, once every quarter.

2, machine lubrication

According to the table below fixed-point, qualitative, quantitative, lubrication on a regular basis.
