Technical Field

[0001] This utility model relates to the field of chemical processing equipment technology, and in particular to a centrifugal chemical production filter. Background Technology

[0002] In chemical production processes, centrifugal filters are often used for solid-liquid separation. Centrifugal filters are generally used to separate suspensions with a high solid content and large particles. When the mixture to be filtered enters the high-speed rotating filter cartridge, due to the centrifugal force, the solid particles are trapped on the inner wall of the filter cartridge, while the purified liquid flows out through the filter cartridge.

[0003] Chemical engineering is the process of producing chemical products by changing the structure, composition, and form of substances through chemical reactions. A large amount of wastewater is generated during the chemical production process. The wastewater contains a large amount of waste residue that needs to be filtered. Therefore, a filter is used to filter the waste residue. A porous filter is a device that achieves solid-liquid separation.

[0004] The existing chemical production filter residue filter has the following drawbacks. The filter generally uses filter plates for direct filtration. When too much filter residue accumulates on the top of the filter plates, it can cause blockage. The filter plates need to be cleaned and replaced regularly. When cleaning the waste residue inside the filter, wastewater discharge cannot continue. Moreover, the maintenance time is long and the efficiency of chemical wastewater discharge is affected. Therefore, a centrifugal chemical production filter residue filter is proposed to solve the above problems. Utility Model Content

A semi-circular sealing plug is fixedly connected to the side outer wall of the rotating rod. A feed pipe is fixedly connected to the top outer wall of the diversion pipe.

[0007] As a further description of the above technical solution: the auxiliary mechanism includes a frosted sleeve, which is fixedly connected to the outer side wall of the adjustment disc. The outer front wall of the adjustment disc has a directional mark. A filter cylinder is slidably connected to the inner top wall of the filter body.

[0017] 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.

[0018] Reference Figures 1-3This utility model provides an embodiment of a centrifugal chemical production filter, comprising a discharge pipe 1 and a fixed base 2. The fixed base 2 is fixedly connected to the bottom outer wall of the discharge pipe 1, and a filter body 3 is fixedly connected to the top outer wall of the discharge pipe 1. An adjustment mechanism 4 is provided on the filter body 3, and an auxiliary mechanism 5 is provided on the adjustment mechanism 4. The adjustment mechanism 4 includes a diversion pipe 42, which is fixedly installed on the right inner wall of the filter body 3. The diversion pipe 42 serves as a material diversion channel. By being fixed to the right inner wall of the filter body 3, it can guide the material from the feed pipe 41 to different filter bodies 3. A rotating rod 40 is rotatably connected to the inner wall of the filter via a bearing. An adjusting disc 43 is fixedly connected to the outer side wall of the rotating rod 40. A paddle 44 is slidably connected to the inner right side wall of the adjusting disc 43. A limit rod 45 is fixedly connected to the outer rear wall of the paddle 44. A compression spring 46 is fixedly connected to the outer front wall of the paddle 44. A sealing plate 47 is fixedly connected to the outer front wall of the diversion pipe 42. A semi-circular sealing plug 48 is fixedly connected to the outer side wall of the rotating rod 40. The semi-circular sealing plug 48 rotates with the rotating rod 40 and can seal one end of the diversion pipe 42, controlling the material to flow only to the other end of the filter body 3. A feed pipe 41 is fixedly connected to the outer top wall of the diversion pipe 42.

[0019] Reference Figures 2-4 The rotating rod 40 penetrates the front outer wall of the diversion pipe 42. There are two filter bodies 3. The two ends of the diversion pipe 42 are fixedly connected to the inner side walls of the two filter bodies 3. The front and rear outer walls of the lever 44 are fixedly connected with a frosted pad. The frosted pad increases the friction between the lever 44 and the hand, prevents slippage when pulling, and improves the stability of operation. The end of the compression spring 46 away from the lever 44 is fixedly connected to the front inner wall of the adjustment plate 43. The outer side wall of the limit rod 45 is fixedly connected with a wear-resistant sleeve. The wear-resistant sleeve reduces the wear between the limit rod 45 and the sealing plate 47, extends the service life of the limit rod 45, and ensures the stability of the limit function. The limit rod 45 is snapped into the front inner wall of the sealing plate 47. The rotating rod 40 penetrates the front outer wall of the sealing plate 47. The semi-circular sealing plug 48 contacts the inner side wall of the diversion pipe 42.

[0020] Reference Figures 3-4The auxiliary mechanism 5 includes a frosted sleeve 51, which is fixedly connected to the outer side wall of the adjusting plate 43. The frosted sleeve 51 increases the friction between the adjusting plate 43 and the hand, making it easier to rotate the adjusting plate 43 and less prone to slippage. A directional mark 52 is provided on the front outer wall of the adjusting plate 43 to indicate the current position of the adjusting plate 43, helping the operator to quickly determine which filter body 3 the material is flowing to, thus improving the accuracy of adjustment. A filter cylinder 53 is slidably connected to the top inner wall of the filter body 3. A connection interface 54 is provided on the front outer wall of the filter cylinder 53, and a top cover is fixedly connected to the top outer wall of the filter cylinder 53. 55. The top inner wall of the top cover 55 is threaded with a bolt 56. The top of the bolt 56 is fixedly connected to a handle 57. The front outer wall of the indicator 52 is fixedly connected to an indicator coating. The indicator coating (such as a bright coating) enhances the visibility of the indicator 52, allowing the operator to clearly observe it in complex environments and improve adjustment efficiency. The interface 54 is connected to the diversion pipe 42. The bolt 56 is threadedly connected to the top inner wall of the filter body 3. The side outer wall of the handle 57 is fixedly connected to a silicone sleeve. The silicone sleeve increases the grip comfort of the handle 57 and enhances friction to prevent slippage during rotation, thus improving the operating experience.

[0021] Working principle: By pulling the lever 44, the limiting rod 45 is moved, and the limiting rod 45 separates from the inner wall of the front side of the sealing plate 47, releasing the rotation limit of the adjusting plate 43. Then, rotating the adjusting plate 43 causes the rotating rod 40 to rotate, which in turn causes the semi-circular sealing plug 48 to rotate. The rotation of the semi-circular sealing plug 48 adjusts the material entering through the feed pipe 41 to be guided to either end of the diversion pipe 42, allowing for convenient maintenance of the other end of the filter body 3 without affecting the continued production of filter residue in the other filter body 3. At the same time, the current rotation position of the adjusting plate 43 can be seen through the indicator mark 52, making it convenient for personnel to switch adjustments. Meanwhile, the filter residue inside the filter cylinder 53 can be removed by rotating the handle 57 and removing the two bolts 56. Then, the top cover 55 is lifted to pull the filter cylinder 53 out of the filter body 3. No special tools or disassembly of many parts are required, making it convenient for personnel to clean and maintain.

[0022] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
