Description

Technical Field

[0001] This utility model relates to the field of mold release agent filtration technology, specifically a coolant-type mold release agent filtration and purification device. Background Technology

[0002] A mold release agent is an interface coating applied to the surfaces of two objects that are prone to adhesion. It makes the surfaces easy to separate, smooth, and clean. Metal die-casting mold release agents are mainly used in various molding operations of metal materials such as aluminum alloys, magnesium alloys, and zinc alloys. Mold release agents are chemically resistant and do not dissolve when in contact with the chemical components of different resins (especially styrene and amines). Mold release agents also have heat and stress resistance and are not easily decomposed or worn. Mold release agents adhere to the mold and do not transfer to the processed parts, and do not hinder painting or other secondary processing operations. Due to the rapid development of injection molding, extrusion, calendering, compression molding, and die casting processes, the usage of mold release agents has also increased significantly.

[0003] Die-casting release agent waste liquid contains a large amount of metal debris. When recycling, this metal debris needs to be filtered out. Furthermore, due to the high temperature of the die-cast parts, the temperature of the release agent waste liquid is also very high. This high temperature not only affects the service life and filtration efficiency of the filter element but also hinders subsequent storage and collection. Therefore, we propose a coolant-type release agent filtration and purification device. Utility Model Content

[0004] The purpose of this invention is to provide a cooling liquid type mold release agent filtration and purification device. By installing a copper pipe that allows cool water to pass through inside the filter box, when the filter cotton is placed inside the filter box, the copper pipe is inserted into the inner groove of the filter cotton. This allows the mold release agent waste liquid to absorb heat and cool down during filtration and purification. The temperature of both the filtration area and the filtered mold release agent is reduced, which is beneficial to maintaining the long service life and filtration effect of the filter cotton, and facilitates the storage of the cooled mold release agent. This solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a coolant release agent filtration and purification device, comprising a filter box and filter cotton, wherein the filter cotton is placed inside the filter box through an opening at the top of the filter box, and a cover plate is fixed to the top surface of the filter box by bolts to seal the opening at the top of the filter box; both sides of the filter box are connected to conduits communicating with its interior; copper pipes arranged in an S-shape are fixed inside the filter box, and the two ends of the copper pipes are respectively connected to an inlet pipe and a return pipe that penetrate to the outside of the filter box; an inner groove is provided inside the filter cotton so that the copper pipes are inserted into the inner groove of the filter cotton.

[0006] By adopting the above technical solution, cool water is circulated inside the copper pipe, and then the release agent waste liquid is filtered and purified through the filter box. Because the cool water flowing in the copper pipe can absorb the heat of the release agent and cool it down, the temperature of the filtration area and the released agent after filtration are reduced, which is beneficial to the storage of the release agent and ensures the filtration effect and service life of the filter cotton.

[0007] Optionally, the bottom two sides of the cover plate are vertically fixed with plugs, which are inserted into slots provided on the surface of the filter cotton below, and the outer ring of the plugs is fixed with a plurality of protrusions that abut against the inner surface of the slots.

[0008] By adopting the above technical solution, when the cover plate is removed and the filter cotton needs to be taken out, the outer ring of the plug can be pressed against the protrusion inside the slot, which makes it easy to take the filter cotton out from the inside of the filter box.

[0009] Optionally, a drain pipe is vertically connected to the bottom center of the filter box, and a screw cap is connected to the drain pipe by screwing.

[0010] By adopting the above technical solution, the inside of the filter box can be rinsed when the filter cotton is removed, and the rinsed wastewater can be discharged from the drain pipe.

[0011] Optionally, a valve is installed on the water inlet pipe, and the valve is connected to the inside of the water inlet pipe.

[0012] By adopting the above technical solution, the opening or closing status of the water inlet pipe is controlled by a valve.

[0013] Optionally, the inner wall surface of the filter box is provided with a heat insulation layer, which is evenly distributed on the inner surface of the filter box.

[0014] By adopting the above technical solutions, the heat insulation effect of the filter box can be improved.

[0015] Optionally, the front and rear ends of the filter cotton are respectively attached to the front and rear end surfaces inside the filter box, and the upper and lower ends of the filter cotton are respectively pressed against the cover plate and the bottom surface of the filter box.

[0016] By adopting the above technical solution, the filter cotton is made in close contact with the inner wall of the filter box, so that the release agent waste liquid can be filtered through the filter cotton.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application is to install a copper pipe that allows cool water to pass through inside the filter box. When the filter cotton is placed inside the filter box, the copper pipe is inserted into the inner groove of the filter cotton. This allows the release agent waste liquid to absorb heat and cool down when it is filtered and purified. The temperature of the filtration area and the released agent after filtration are both reduced, which is beneficial to maintaining the long service life and filtration effect of the filter cotton, and facilitates the storage of the cooled release agent.

[0019] 2. The technical solution of this application provides a plug with a protrusion on the outer ring at the bottom of the cover plate. When the plug is inserted into the slot of the filter cotton, the protrusion is pressed against the slot. After the cover plate is removed, the filter cotton can be easily pulled out.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a coolant release agent filtration and purification device, including a filter box 1 and filter cotton 2. The filter cotton 2 is placed inside the filter box 1 through an opening at the top of the filter box 1. A cover plate 4 is installed and fixed on the upper surface of the filter box 1 by bolts 41, thereby sealing the opening at the top of the filter box 1. The front and rear ends of the filter cotton 2 are respectively attached to the front and rear end surfaces inside the filter box 1. The upper and lower ends of the filter cotton 2 are respectively pressed against the cover plate 4 and the bottom surface of the filter box 1. Both sides of the filter box 1 are connected to conduits 11 that communicate with its interior, so that the waste liquid of the release agent enters the filter box 1 from one conduit 11, is filtered and purified by the filter cotton 2, and is then discharged to the outside from the other conduit 11.

[0026] Both sides of the bottom of the cover plate 4 are vertically fixed with plugs 42. The plugs 42 are inserted into the slots 22 provided on the surface of the filter cotton 2 below. The outer ring of the plugs 42 is fixed with multiple protrusions 421. When the plugs 42 are inserted into the slots 22, the protrusions 421 press against the inner surface of the slots 22. When the filter cotton 2 needs to be replaced, the bolts 41 are unscrewed to release the lock on the cover plate 4. When the cover plate 4 is pulled upward, the filter cotton 2 can also be taken out outward because the protrusions 421 press against the inner surface of the slots 22, making it easy to replace the filter cotton 2 later. When the filter cotton 2 is removed, the inside of the filter box 1 can also be rinsed. Therefore, a drain pipe 12 is vertically connected in the middle of the bottom of the filter box 1. During normal use, a screw cap 121 is connected to the drain pipe 12 by screwing. When rinsing the inside of the filter box 1, the screw cap 121 is unscrewed to allow the sewage to be discharged from the drain pipe 12.

[0027] Inside the filter box 1, there are S-shaped copper tubes 3. The two ends of the copper tubes 3 are connected to an inlet pipe 31 and a return pipe 32 that pass through to the outside of the filter box 1, respectively. The filter cotton 2 has an inner groove 21, into which the copper tubes 3 are inserted. A valve 311 is installed on the inlet pipe 31 and is connected to the inside of the inlet pipe 31. Before filtration, the inlet pipe 31 and the outlet pipe are connected to the cool water supply pipe and the return pipe through connectors, respectively. After opening the valve 311, flowing cool water can be introduced into the copper tubes 3, which can absorb heat in the filtration area, reduce the temperature of the filter cotton 2 area, ensure its service life and ensure the filtration effect, and also reduce the temperature of the release agent after filtration.

[0028] A heat insulation layer 13 is provided on the inner wall surface of the filter box 1. The heat insulation layer 13 is evenly distributed on the inner surface of the filter box 1 and can serve the purpose of heat insulation during use.

[0029] In use, the two conduits 11 on both sides are connected to the supply pipe and discharge pipe of the release agent waste liquid, respectively. The lower water inlet pipe 31 is connected to the cool water supply pipe, and the return water pipe 32 is connected to the return pipe. After opening the valve 311, the copper pipe 3 inside the filter box 1 is circulated with cool water. The release agent waste liquid flows from one conduit 11 into the interior of the filter box 1, where it is filtered by the filter cotton 2. At the same time, the cool water flowing in the copper pipe 3 absorbs the heat in the release agent waste liquid, thereby reducing the temperature of the filtration area and lowering the temperature of the filtered release agent. It is then discharged from the other conduit 11. After a period of use, stop feeding the release agent into the filter box 1, unscrew the bolt 41 to remove the cover plate 4, and lift the cover plate 4 upwards. Because the protrusion 421 on the outer ring of the plug 42 is pressed against the inner surface of the slot 22, the filter cotton 2 can be pulled out to the outside and removed. Then, unscrew the screw cap 121 on the bottom drain pipe 12 to flush the inside of the filter box 1 and let the sewage drain from the drain pipe 12. Then screw the screw cap 121 back on, replace the new filter cotton 2, and reinstall the locking cover plate 4 with the bolt 41 to complete the replacement of the filter cotton 2. The filtration work can then continue.
