DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model.

[0025] Embodiment 1:

[0026] Referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, a filtering reactor, comprising a filtering chamber 1, in which a filter plate 2 is fixedly installed, and further comprising: a moving seat 301 disposed above the filter plate 2, wherein the moving seat 301 is slidably connected in the filtering chamber 1, and a cover shell 3 is detachably connected to the moving seat 301, and the cover shell 3 is in fit with the filter plate 2; a hollow box 501, disposed below the moving seat 301 and used in cooperation with the cover shell 3, wherein a plurality of jet nozzles 502 fixedly communicated with its inner cavity are arranged on the hollow box 501, and a guiding groove 505 is formed in the filtering chamber 1; a connecting rod 5, one end of which is fixedly connected to the moving seat 301 and the other end is fixedly connected to the hollow box 501, and the connecting rod 5 is slidably connected in the guiding groove 505; a booster pump 503, fixedly installed on the filtering chamber 1, and the output end of the booster pump 503 is fixedly communicated with the hollow box 501 through a pipeline 504; a driving and moving mechanism, disposed on the filtering chamber 1 and used for driving the moving seat 301 to move.

[0027] The driving and moving mechanism includes a reciprocating lead screw 305 and a motor 304. The reciprocating lead screw 305 is rotatably connected in the filtering chamber 1, the motor 304 is fixedly installed on the filtering chamber 1, the reciprocating lead screw 305 is fixedly connected to the output end of the motor 304, and the moving seat 301 is in threaded connection with the reciprocating lead screw 305.

[0028] It further includes guide rods 306 symmetrically and fixedly connected in the filtering chamber 1, and the moving seat 301 is slidably connected to the guide rods 306.

[0029] When it is necessary to filter and remove impurities from liquid materials, first pour the materials to be filtered into the filtering chamber 1. At this time, the liquid materials flow out through the filter holes of the filter plate 2 and then flow to the bottom of the filtering chamber 1, while the solid impurities in the liquid materials are blocked on the filter plate 2, so as to filter the liquid materials and thus reduce the impurities in the liquid materials;

[0030] At the same time, during the filtering of the liquid materials, start the booster pump 503. The booster pump 503 sucks external gas, then transports the sucked gas into the hollow box 501 through the pipeline 504, and finally sprays it out through the jet nozzles 502, and then sprays it onto the filter plate 2, so as to perform reverse cleaning on the filter holes of the filter plate 2, thereby keeping the filter plate 2 unobstructed and preventing the filter holes of the filter plate 2 from being blocked during the filtering process, and reducing the efficiency of filtering and removing impurities from the liquid materials;

[0031] Meanwhile, the motor 304 is started, and the motor 304 drives the reciprocating lead screw 305 to rotate. The reciprocating lead screw 305 drives the moving seat 301 to drive the cover 3 to move left and right reciprocally along the surface of the filter plate 2. At the same time, when the moving seat 301 moves, the hollow box 501 is driven to move synchronously through the connecting rod 5, so that the air jet nozzle 502 continuously jetting air on the hollow box 501 can comprehensively back-clean the filter holes of the filter plate 2, thereby ensuring the overall smoothness of the filter plate 2 and improving the filtration efficiency of the liquid material.

[0032] It should be noted that the pipeline 504 is a stretchable and shrinkable hose, so the pipeline 504 will not interfere with the movement of the moving seat 301 and the hollow box 501.

[0033] It should be added that an activated carbon filter screen (not shown in the figure) is provided inside the input end of the booster pump 503. When the booster pump 503 sucks external gas, the gas contacts with the activated carbon filter screen. Due to the developed pore structure and rich microporous tissue inside the activated carbon, these microporous tissues have a strong adsorption force field. When the gas contacts with the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particulate matter in the air into the micropores, and thus can purify the gas.

[0034] Embodiment 2:

[0035] Refer to Figure 1 、 Figure 3 and Figure 7 A filtration reactor is basically the same as that in Embodiment 1. Further, a discharge box 101 is fixedly communicated with the bottom of the filtration chamber 1. One end of the discharge box 101 away from the filtration chamber 1 is open. A plug-in slot is provided on the side wall of the discharge box 101, and a blocking plate 102 is arranged in the plug-in slot. The blocking plate 102 is used to close the opening of the discharge box 101. Air cylinders 104 are fixedly installed on the outer walls on both sides of the discharge box 101, and the output ends of the air cylinders 104 are fixedly connected with the blocking plate 102.

[0036] A sealing sleeve 103 is fixedly installed on the blocking plate 102, and the sealing sleeve 103 is in close fit with the wall of the plug-in slot.

[0037] When filtering and removing impurities from the liquid material, the air cylinder 104 is started, and the air cylinder 104 pushes the blocking plate 102 to move into the plug-in slot until the blocking plate 102 is completely inserted into the plug-in slot, thereby closing the opening of the discharge box 101.

[0038] When the baffle 102 is fully inserted into the insertion slot, the sealing sleeve 103 is squeezed by the baffle 102 and closely fits against the wall of the insertion slot, thereby achieving the purpose of increasing the sealing performance at the connection between the baffle 102 and the insertion slot, preventing the filtered material from leaking through the gap at the connection between the baffle 102 and the insertion slot, and thus reducing the waste of the material.

[0039] After the filtration and impurity removal of the liquid material are completed, the air cylinder 104 is started. The air cylinder 104 pushes the baffle 102 to move out of the insertion slot, thereby opening the opening of the discharge box 101. At this time, the liquid material can be discharged from the filtration chamber 1 through the discharge box 101.

[0040] Embodiment 3:

[0041] Refer to Figure 3 、 Figure 4 and Figure 5 A filtration reactor is basically the same as that in Embodiment 1. Further, on both sides of the moving seat 301, there are fixedly connected bellows sleeves 4. The bellows sleeves 4 are sleeved on the reciprocating lead screw 305, and the side of the bellows sleeve 4 away from the moving seat 301 is fixedly connected to the inner wall of the filtration chamber 1. Through the arrangement of the bellows sleeves 4, the reciprocating lead screw 305 can be protected, preventing particulate impurities from adhering to the surface of the reciprocating lead screw 305, thereby ensuring that the reciprocating lead screw 305 can drive the moving seat 301 to move smoothly on the guide rod 306.

[0042] A connection block 302 is fixedly connected to the cover shell 3. The connection block 302 is detachably connected to the moving seat 301 through a fixing bolt 303. When it is necessary to clean the particulate impurities blocked in the cover shell 3, by unscrewing the fixing bolt 303 used to limit and fix the connection block 302, the cover shell 3 can be removed from the moving seat 301, facilitating the staff to clean the particulate impurities blocked in the cover shell 3.

[0043] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention.
