Description

Technical Field

[0001] This utility model relates to the field of defoamer production technology, specifically a filter box for defoamer production. Background Technology

[0002] Defoamer is a substance that can reduce the surface tension of water, solutions, suspensions, etc., to prevent foam formation, or reduce or eliminate existing foam. In the production process of defoamer, a filter box is required to filter the liquid. In the existing technology, the filter screen in the filter box needs to be replaced and cleaned, which requires the machine to be stopped, making it difficult to continuously filter the liquid and resulting in less than ideal production efficiency.

[0003] For example, patent publication number CN220405060U describes a filter box for defoamer production, including a primary filter box. A motor is fixedly installed on the top of the primary filter box, and a filter media cylinder is movably mounted at the output end of the motor. A guide pump is fixedly installed on one side of the primary filter box, and a fine filter box is fixedly installed on one side of the guide pump. Constant temperature heating plates are fixedly installed on both sides inside the fine filter box, and a moving component is fixedly installed at the bottom of the fine filter box. This invention, by fixing the fine filter box on one side of the guide pump, allows the motor to drive the filter media cylinder to rotate, then the filter media cylinder discharges the liquid, facilitating preliminary filtration by workers. The guide pump then guides the pre-filtered liquid through a guide pipe into the fine filter box. Then, a first filter screen and a second filter screen made of different micropores perform multi-stage filtration of the liquid, improving the filtration effect of the defoamer production liquid and thus improving the quality of defoamer production. However, this design suffers from the problem that the machine needs to be stopped when the filter screens in the filter box are replaced or cleaned, making it difficult to continuously filter the liquid, resulting in less than ideal production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a filter box for defoamer production, which solves the problem that the filter screen in the filter box needs to be replaced and cleaned, making it difficult to continuously filter the liquid and resulting in less than ideal production efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a filter box for defoamer production, including a base, a liquid tank fixedly connected to one side of the top of the base, and a switching filter mechanism connected to one end of the liquid tank;

[0006] The switching filtration mechanism includes a liquid delivery pump, the output end of which is connected to a switching seat. Two connecting pipes are connected to the end of the switching seat, and a housing is fixedly connected to the end of each of the two connecting pipes. A top cover is provided on the top of each housing, and handles are fixedly connected to both sides of the top cover. Multiple filter plates are provided at the bottom of the top cover, and a quick-release assembly is provided between the filter plates and the top cover. Two guide rods are fixedly connected inside the switching seat, and a movable frame is slidably connected to the two guide rods. Two valve plates are fixedly connected to the movable frame, and multiple connecting brackets are fixedly connected to one end of each movable frame. A switching screw is threadedly connected to the interior of each connecting bracket, and a handwheel is fixedly connected to the end of the switching screw.

[0007] Preferably, the input end of the liquid delivery pump is connected to the liquid tank, and the output end of the liquid delivery pump is connected to the switching seat, so that the liquid delivery pump can deliver the liquid into the switching seat.

[0008] Preferably, the cross-sectional area of ​​both valve plates is larger than the cross-sectional area of ​​the two connecting pipes, and a sealing ring is installed on the side of the valve plate near the connecting pipe, so that the valve plate can cover and block the connecting pipe to prevent the liquid from entering the inside of the connecting pipe.

[0009] Preferably, the switching screw is rotatably connected to the inner wall of the switching seat, and one end of the switching screw passes through the switching seat and extends to the outside of the switching seat, so that the switching screw can rotate.

[0010] Preferably, the quick-installation assembly includes four mounting screws, which are respectively fixedly installed at the four bottom corners of the top cover. Multiple connecting sleeves are fixedly connected to the filter plate, and these connecting sleeves match the mounting screws. A locking threaded sleeve is fixedly connected to the top of each connecting sleeve, and multiple elastic threaded blocks are fixedly connected to the top of each locking threaded sleeve. A locking nut is threadedly connected to the outer side of the locking threaded sleeve, and a push rod is fixedly connected to the locking nut. The multiple elastic threaded blocks are inclinedly arranged on the locking threaded sleeve, and threaded grooves are formed on the inner surface of each elastic threaded block, matching the mounting screws, thus facilitating quick replacement of the filter plate.

[0011] This invention provides a filter box for defoamer production. Compared with the prior art, it has the following advantages:

[0012] 1. The filter box for defoamer production uses a handwheel to move the valve plates, causing two valve plates to block the previously working connecting pipe and open the other unused connecting pipe, thus changing the flow direction of the liquid. The liquid pump then sends the liquid from the previously working box into the unused box. The filter plates can be removed from the previously working box using the handle, allowing for cleaning and replacement of the filter plates without stopping the machine. This continuous filtration of the liquid effectively improves production efficiency.

[0013] 2. The filter box for defoamer production uses a connecting sleeve fitted onto the mounting screw. Then, the push rod is pushed, which drives the locking nut to rotate. The rotating locking nut moves upward under the action of the locking threaded sleeve. The movement of the locking nut pushes multiple inclined elastic threaded blocks toward the mounting screw, and the threaded grooves lock them onto the mounting screw for locking. This allows for convenient and quick replacement and cleaning of the filter plates. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a filter box for defoamer production, including a base 1, a liquid tank 3 fixedly connected to one side of the top of the base 1, and a switching filter mechanism 2 connected to one end of the liquid tank 3. The switching filter mechanism 2 can be used to perform cleaning and replacement operations without stopping the machine, and can continuously filter the liquid, thereby effectively improving production efficiency.

[0021] The switching filtration mechanism 2 includes a liquid delivery pump 201, the output end of which is connected to a switching seat 202. The input end of the liquid delivery pump 201 is connected to a liquid tank 3, and the output end of the liquid delivery pump 201 is connected to the switching seat 202, allowing the liquid delivery pump 201 to deliver liquid into the switching seat 202. Two connecting pipes 203 are connected to the end of the switching seat 202, and a housing 204 is fixedly connected to the end of each of the two connecting pipes 203. A top cover 205 is provided on the top of the two housings 204, and handles 206 are fixedly connected to both sides of the top of the top cover 205. Multiple filter plates 207 are provided at the bottom of the top cover 205, enabling multiple filtration of the liquid and improving the filtration effect. A quick-release assembly 4 is provided between the filter plates 207 and the top cover 205. Two guide rods 208 are fixedly connected inside the switching seat 202, and a movable frame 209 is slidably connected to the two guide rods 208, allowing for the movement of the movable frame 209. The movable frame 209 has two valve plates 210 fixedly connected to it. The cross-sectional area of ​​the two valve plates 210 is larger than that of the two connecting pipes 203. A sealing ring is installed on the side of the valve plate 210 near the connecting pipe 203, so that the valve plate 210 can cover and block the connecting pipe 203, so that the two connecting pipes 203 are always in a state of one being connected and the other being closed, preventing the liquid from entering the interior of the connecting pipe 203. Multiple connecting frames 211 are fixedly connected to one end of the movable frame 209. A switching screw 212 is threaded inside the multiple connecting frames 211. A handwheel 213 is fixedly connected to the end of the switching screw 212. The switching screw 212 is rotatably connected to the inner wall of the switching seat 202, and one end of the switching screw 212 passes through the switching seat 202 and extends to the outside of the switching seat 202, so that the switching screw 212 can rotate, thereby allowing the handwheel 213 to drive the switching screw 212 to rotate.

[0022] Please see Figure 2 and Figure 4The quick-installation component 4 includes four mounting screws 401, which are respectively fixedly installed at the four bottom corners of the top cover 205. Multiple connecting sleeves 402 are fixedly connected to the filter plate 207. These connecting sleeves 402 match the mounting screws 401, allowing them to fit onto the screws. Each connecting sleeve 402 has a locking threaded sleeve 403 fixedly connected to its top. Multiple elastic threaded blocks 406 are fixedly connected to the top of each locking threaded sleeve 403. A locking nut 404 is threaded onto the outer side of the locking threaded sleeve 403. A push rod 405 is fixedly connected to the locking nut 404. The multiple elastic threaded blocks 406 are inclinedly positioned on the locking threaded sleeve 403, allowing the elastic threaded blocks 406 to... The 06 can remain separated from the mounting screw 401 and can deform under external force to lock onto the mounting screw 401. The inner surface of the elastic threaded block 406 has a threaded groove that matches the mounting screw 401. By putting the connecting sleeve 402 on the mounting screw 401 and then pushing the push rod 405, the push rod 405 drives the locking nut 404 to rotate. The locking nut 404 rotates and moves upward under the action of the locking threaded sleeve 403. The movement of the locking nut 404 pushes multiple inclined elastic threaded blocks 406 to approach the mounting screw 401 and locks onto the mounting screw 401 using the threaded groove. This allows for convenient and quick replacement and cleaning of the filter plate 207.

[0023] During operation, turning the handwheel 213 causes the switching screw 212 to rotate, which in turn moves the connecting frame 211. This movement of the connecting frame 211 then moves the movable frame 209 along the guide rod 208. The movable frame 209 then moves the valve plate 210, causing the two valve plates 210 to block the previously working connecting pipe 203 and open the other unused connecting pipe 203. This changes the flow direction of the liquid. The liquid pump 201 then delivers the liquid from the previously working tank 204 into the unused tank 204. The filter plate 207 is then removed from the previously working tank 204 using the handle 206. The filter plate 207 is cleaned and replaced without stopping the machine, allowing for continuous filtration of the liquid and effectively improving production efficiency.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
