Description

Technical Field

[0001] This utility model relates to the field of ceramic raw material slurry pressure filtration technology, and specifically discloses a ceramic raw material slurry pressure filtration device. Background Technology

[0002] A filter press is a mechanical device that uses a special filter medium to apply pressure to the material, causing the liquid to seep out. It is a commonly used solid-liquid separation device that was applied to chemical production in the early 18th century and is still widely used in industries such as chemical, pharmaceutical, metallurgy, dye, food, brewing, ceramics and environmental protection.

[0003] A Chinese patent (CN213865878U) discloses a filter press device for ceramic raw material slurry. The device body includes a bottom plate, side plates, and a top plate. The side plates are located on top of the bottom plate, and the top plate is located on top of the side plates. A drive motor is vertically mounted on the top of the top plate. The output end of the drive motor passes through the top plate and is fixedly connected to a threaded rod. One end of the threaded rod is rotatably connected to the top of the bottom plate. A support rod is installed inside the cavity of the device body, and the support rod passes through a pressure cover. A filter cylinder is installed on the top of the bottom plate, and a support plate is installed inside the cavity of the filter cylinder. A second filter cotton is installed on the top of the support plate. An electric cylinder is installed at the bottom of the bottom plate, and the output end of the electric cylinder is fixedly connected to the support plate.

[0004] During the sludge discharge process after each filtration, the above-mentioned device leaves the sludge cake stuck on the filter cotton at the top of the support plate due to the horizontal placement of the support plate. This requires manual cleaning, which is cumbersome. Furthermore, the filter cylinder is fixed to the top of the base plate, making it inconvenient to disassemble and clean, thus making it inconvenient to use. Therefore, a filtration device for ceramic raw material sludge is needed to solve the above problems. Utility Model Content

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0019] Please see Figure 1-4 A filter press device for ceramic raw material slurry includes a base frame 1, and a filter press assembly and a collection assembly are arranged above the base frame 1. The filter press assembly includes a bracket 9 fixedly connected to the upper end of the base frame 1. A support rod 10 is fixedly connected to the inner wall of the bracket 9. A support seat 12 is detachably connected to the front end of the support rod 10 by bolts. A filter cartridge 13 with a feed pipe 11 is fixedly connected to the front end of the support seat 12. Electric push rods 14 are installed at both ends of the bracket 9. Fixed seats 15 are fixedly connected to the output ends of the two electric push rods 14. Filter plates 17 are detachably connected to the opposite sides of the two fixed seats 15 by bolts. Filter cotton is fixedly connected to the opposite sides of the two filter plates 17. The collection assembly includes two symmetrically distributed upright plates 2 fixedly connected to the upper end of the base frame 1. A lead screw 3 is rotatably connected between the two upright plates 2. Two internal threaded blocks 6 are threadedly connected to the outer wall of the lead screw 3. A collection frame 7 is fixedly connected to the upper end of each of the two internal threaded blocks 6.

[0020] In this embodiment: After the ceramic raw material slurry is injected into the filter cylinder 13 through the feed pipe 11, the electric push rods 14 at both ends of the support 9 are started simultaneously, pushing the fixed seat 15 to move the filter plate 17 towards the center of the filter cylinder 13. The filter cotton on the inner side of the filter plate 17 applies pressure to the slurry. After the liquid seeps out through the filter holes of the filter cylinder 13, it drips into the collection frame 7 below. After the pressure filtration is completed, the electric push rod 14 drives the filter plate 17 to reset. The motor 4 drives the lead screw 3 to rotate, causing the two internal threaded blocks 6 to separate the collection frame 7. One of the electric push rods 14 pushes the corresponding filter plate 17 to push the mud cake out of the filter cylinder 13 to the designated collection frame 7. The other collection frame 7 continues to collect the residual liquid. The filter cylinder 13 and the filter plate 17 can be cleaned by removing the bolts between the support seat 12 and the support rod 10, and between the filter plate 17 and the fixed seat 15. The drain pipe on the outer wall of the collection frame 7 discharges the filtrate.

[0021] As a technical optimization of this utility model, auxiliary blocks 16 are fixedly connected to the upper ends of the two fixed seats 15, and guide rods are fixedly connected to the outer walls of the two auxiliary blocks 16. The two guide rods pass through the bracket 9 and are slidably connected to the bracket 9.

[0022] In this embodiment, both guide rods pass through the bracket 9 and are slidably connected to the bracket 9, which can increase the stability of the movement of the two fixed seats 15.

[0023] As a technical optimization of this utility model, a motor 4 with its output end fixedly connected to the lead screw 3 is located on the outer wall of the right end plate 2.

[0024] In this embodiment, the lead screw 3 can be driven to rotate by the motor 4.

[0025] As a technical optimization of this utility model, the diameters of the two filter plates 17 are the same as the inner diameter of the filter cylinder 13.

[0026] In this embodiment: ensure that the filter plate 17 and the inner wall of the filter cylinder 13 are in close contact to prevent the slurry from leaking from the gap between the filter plate 17 and the filter cylinder 13 during the filter pressing process.

[0027] As a technical optimization of this utility model, the upper end of the base frame 1 is fixedly connected to two left and right distributed first positioning blocks 8 and second positioning blocks 5.

[0028] In this embodiment: the first positioning block 8 can limit the movement position of the left end internal thread block 6, and the second positioning block 5 can limit the movement position of the right end internal thread block 6.

[0029] As a technical optimization of this utility model, the lower ends of the two internal threaded blocks 6 abut against the upper end of the base frame 1.

[0030] In this embodiment, the lower ends of the two internal threaded blocks 6 abut against the upper end of the base frame 1, which can prevent the two internal threaded blocks 6 from rotating axially.

[0031] As a technical optimization of this utility model, the outer wall of the collection frame 7 is connected to a drain pipe.

[0032] In this embodiment, the liquid inside the collection box 7 can be easily drained through the drain pipe.

[0033] The working principle and usage process of this utility model are as follows: Ceramic raw material slurry is injected into the filter cylinder 13 through the feed pipe 11. Then, the electric push rods 14 at both ends of the support 9 are started simultaneously, pushing the fixed seat 15 to move the filter plate 17 towards the center of the filter cylinder 13, so that the filter cotton on the inner side of the filter plate 17 is in full contact with the slurry and pressure is applied. The liquid seeps out through the filter holes of the filter cylinder 13 and drips into the collection frame 7 below. After the filtration is completed, the electric push rods 14 drive the filter plate 17 to reset. At this time, the motor 4 drives the lead screw 3 to rotate, and the corresponding... The collection frame 7 moves to the bottom of the filter plate 17. One collection frame 7 is used to collect mud cake, and the other collection frame 7 is used to collect liquid. When collecting mud cake, the mud cake after pressing is pushed out of the filter cylinder 13 by one of the electric push rods 14 and falls into the corresponding collection frame 7. At the same time, the filter cylinder 13 and the filter plate 17 can be disassembled and cleaned by removing the bolts between the support base 12 and the support rod 10 and the bolts between the filter plate 17 and the fixed base 15. The drain pipe on the outer wall of the collection frame 7 can discharge the collected liquid.
