Description

Technical Field

[0001] This utility model relates to a melting liquid treatment device, specifically a filtration device. Background Technology

[0002] Emulsions are high-performance metalworking fluids with wide applications in metal processing. They effectively prevent workpieces from rusting or being chemically corroded, and also effectively prevent microbial attack. However, over long-term use, emulsions often accumulate a large number of impurities, making reuse and recycling difficult. Therefore, a filtration device is needed for treatment.

[0003] When current filtration devices use filter plates to filter emulsions, the emulsions tend to be concentrated in one spot on the filter plate, which can easily cause blockages in that concentrated area, thus affecting the filtration effect. Utility Model Content

[0004] The main objective of this disclosure is to provide a filtration device that effectively solves the problems raised by the inventors in the background art described above.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A filtration device includes a filter box containing filter plates. A fixed frame is fixedly installed on the upper end of the filter box. Translation screws are rotatably installed on both the front and rear sides of the fixed frame, and two sliding rods are fixedly installed on each side. Translation plates are threaded onto both translation screws, and the two translation plates are slidably connected to the sliding rods on both sides. Openings are formed on both the front and rear inner sides of the fixed frame. A liquid storage cylinder is fixedly installed between the two translation plates via a connecting rod. A liquid outlet pipe is provided at the lower end of the liquid storage cylinder. A rectangular through-slot is formed at the upper end of the filter box, and the liquid outlet pipe extends into the inner side of the filter box through the rectangular through-slot. Emulsion is poured into the liquid storage cylinder and discharged through the liquid outlet pipe onto the filter plates for filtration. Simultaneously, rotating the two translation screws causes the two translation plates to slide on the sliding rods on both sides, thereby moving the liquid storage cylinder left and right to disperse the emulsion through the filter plates, preventing the emulsion from concentrating on the filter plates and clogging them, thus affecting the filtration effect.

[0007] Preferably, the filter box has a disassembly port on the front side and a slot on the inside side of the filter box. The filter plate is movably inserted into the slot and can be detachably installed in the slot by fixing bolts. A baffle is fixedly installed on the front side of the filter plate and a handle is fixedly installed on the front side of the baffle. By unscrewing the fixing bolts and pulling the baffle outward by the handle, the filter plate can be pulled out of the slot, thereby facilitating the removal of the filter plate from the disassembly port for cleaning.

[0008] Preferably, the upper end of the liquid storage cylinder has an injection port, and the lower end is fixedly installed with an electric valve. The input end of the electric valve is connected to the liquid storage cylinder, and the outlet pipe is fixedly installed on the output end of the electric valve. The emulsion can be injected into the liquid storage cylinder through the injection port, and the emulsion can be discharged for use through the outlet pipe by opening the electric valve.

[0009] Preferably, a dual-axis motor is fixedly installed inside the right side of the fixed frame. Transmission rods are fixedly installed on the output shafts at both ends of the dual-axis motor. Bevel gears are fixedly installed on the other ends of the two transmission rods. Bevel gears are also fixedly installed on the rotating shafts at one end of the two translation screws. The bevel gears are meshed in pairs. By driving the two transmission rods to rotate through the dual-axis motor, the bevel gears can be driven to rotate simultaneously, thereby driving the two translation screws to rotate simultaneously for use.

[0010] Preferably, support legs are fixedly installed at the four corners of the lower end of the filter box, and a drain pipe is fixedly installed in the middle of the lower end of the filter box. The drain pipe is equipped with a switch valve. The support legs can support the filter box and raise its height, so as to facilitate the discharge of the filtered emulsion through the drain pipe.

[0011] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0012] In this application, an emulsion is poured into a storage cylinder during filtration, and then discharged through a discharge pipe at the bottom of the cylinder for filtration. Simultaneously, two translation screws are rotated to allow two translation plates to slide on sliding rods on both sides, thereby enabling the storage cylinder to move left and right for discharge. This disperses the emulsion through the filter plates, preventing it from concentrating and clogging the filter plates, which would affect the filtration effect. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-4 The present invention provides the following embodiments:

[0020] A filtration device includes a filter box 1, a filter plate 3 inside the filter box 1, and a fixed frame 8 fixedly installed on the upper end of the filter box 1. Translation screws 9 are rotatably installed on both the front and rear sides of the fixed frame 8, and two sliding rods 10 are fixedly installed on each of the two translation screws 9. Translation plates 11 are threaded onto each of the two translation screws 9, and the two translation plates 11 are slidably connected to the sliding rods 10 on both sides. Openings are provided on both the front and rear inner sides of the fixed frame 8. A liquid storage cylinder 13 is fixedly installed between the two translation plates 11 via a connecting rod 12. The lower end of the liquid storage cylinder 13 has a liquid outlet. The upper end of the filter box 1 has a rectangular through-slot 17. The outlet pipe 16 extends to the inside of the filter box 1 through the rectangular through-slot 17. By pouring the emulsion into the storage cylinder 13, the emulsion is discharged to the filter plate 3 through the outlet pipe 16 for filtration. At the same time, by rotating the two translation screws 9, the two translation plates 11 slide on the sliding rods 10 on both sides, thereby moving the storage cylinder 13 left and right to disperse the emulsion through the filter plate 3 for filtration, preventing the emulsion from concentrating at the position of the filter plate 3 and causing it to clog and affect the filtration effect.

[0021] Specifically, a disassembly port 5 is provided on the front side of the filter box 1, and a slot 2 is provided on the inner side of the filter box 1. The filter plate 3 is movably inserted into the slot 2, and the filter plate 3 is detachably installed in the slot 2 by fixing bolts 4. A baffle 6 is fixedly installed on the front side of the filter plate 3, and a handle 7 is fixedly installed on the front side of the baffle 6. By unscrewing the fixing bolts 4, the baffle 6 can be pulled outward by the handle 7 to pull the filter plate 3 out of the slot 2, thereby disassembling the filter plate 3 from the disassembly port 5 for easy cleaning.

[0022] Specifically, an injection port 14 is provided at the upper end of the liquid storage cylinder 13, and an electric valve 15 is fixedly installed at the lower end. The input end of the electric valve 15 is connected to the liquid storage cylinder 13, and the outlet pipe 16 is fixedly installed on the output end of the electric valve 15. The emulsion can be injected into the liquid storage cylinder 13 through the injection port 14, and the emulsion can be discharged for use through the outlet pipe 16 by opening the electric valve 15.

[0023] Specifically, a dual-axis motor 18 is fixedly installed inside the right side of the fixed frame 8. Transmission rods 19 are fixedly installed on the output shafts at both ends of the dual-axis motor 18. Bevel gears 20 are fixedly installed on the other end of the two transmission rods 19. Bevel gears 20 are also fixedly installed on the rotating shafts at one end of the two translation screws 9. The several bevel gears 20 are meshed in pairs. By driving the two transmission rods 19 to rotate through the dual-axis motor 18, the several bevel gears 20 can be driven to rotate simultaneously, thereby driving the two translation screws 9 to rotate simultaneously for use.

[0024] Specifically, support legs 21 are fixedly installed at the four corners of the lower end of the filter box 1, and a drain pipe 22 is fixedly installed in the middle of the lower end of the filter box 1. A switch valve 23 is provided on the drain pipe 22. The support legs 21 can support the filter box 1 and raise its height, so that the filtered emulsion can be discharged through the drain pipe 22.

[0025] The working principle of this utility model is as follows: First, the emulsion is injected into the storage cylinder 13 through the injection port 14. Then, the electric valve 15 is opened to allow the emulsion to be discharged through the outlet pipe 16 onto the filter plate 3 for filtration. During filtration, the dual-shaft motor 18 is turned on to drive the two transmission rods 19 to rotate, which in turn drives several bevel gears 20 to rotate simultaneously, thereby driving the two translation screws 9 to rotate simultaneously, causing the two translation plates 11 to slide on the slide rods 10 on both sides, thereby driving the storage cylinder 13 to move left and right, so that the emulsion is discharged in a dispersed manner and filtered through the filter plate 3. After the emulsion is filtered, the switch valve 23 is opened to discharge the filtered emulsion through the drain pipe 22. After discharge, the fixing bolt 4 can be unscrewed, and the baffle 6 can be pulled outward by the handle 7 to pull the filter plate 3 out of the slot 2 and out of the disassembly port 5 for cleaning.
