Description

Technical Field

[0001] The utility model relates to the field of chemical production, in particular to a filtering tank used in chemical production. Background Art

[0002] The chemical production process refers to the production process of obtaining valuable products by chemically processing raw materials. Due to the diversity of raw materials and products and the complexity of the production process, tens of thousands of chemical production processes have been formed. Looking at the numerous chemical production processes, they are all organically combined by chemical reactions and several physical operations. Among them, chemical reactions and reactors are the core of chemical production, and physical processes play the role of preparing suitable reaction conditions for chemical reactions and separating and purifying reactants to obtain final products. In the chemical production process, filtration methods are often used to force the fluid in the liquid-solid or gas-solid mixture to pass through a porous filter medium to intercept the suspended solid particles therein, thereby achieving separation of the mixture.

[0003] After searching, the Chinese patent announcement number CN217041672U discloses a chemical filter tank for chemical production. The patent includes a tank body, the inner cavity of the tank body is connected with a first filter screen by bolts, the inner cavity of the tank body is welded with a partition, the top of the partition is provided with a drainage hole, the top of the left side of the tank body is connected with a scraping mechanism by bolts, the top of the tank body is connected with a liquid inlet pipe, both sides of the bottom of the tank body are connected with a liquid discharge pipe, and the bottom of the tank body is connected with a first motor by bolts.

[0028] The utility model is further described below in conjunction with the accompanying drawings:

[0029] like Figure 1 — Figure 8As shown, a filtering tank for chemical production includes a tank body 101, a feed hopper 102 is arranged on the top of the tank body 101, a discharge port 104 is arranged on the bottom of the tank body 101, a first filtering mechanism and a second filtering mechanism are arranged in the tank body 101, the first filtering mechanism includes a fixed plate 201, the fixed plate 201 is connected to the inside of the tank body 101 by bolts, a rotating shaft 202 is rotatably connected to the fixed plate 201, a first filter screen 203 is connected to the rotating shaft 202 by bolts, a bearing plate 204 is connected to the inner side of the tank body 101 by bolts, the bearing plate 204 is used to limit the end of the first filter screen 203 away from the rotating shaft 202, the first filter screen 203 is arranged obliquely, and the second filtering mechanism includes a movable plate 301, the movable plate 301 is movable It is arranged in the tank body 101, and a second filter screen 302 is connected to the movable plate 301 by bolts. The mesh number of the second filter screen 302 is greater than the mesh number of the first filter screen 203. The first filter screen 203 is used for preliminary filtering of large particles in chemical raw materials, which is beneficial to improving the filtration efficiency. The second filter screen 302 is located directly below the first filter screen 203. A plurality of pressure-bearing components are arranged at the bottom of the movable plate 301. A knocking mechanism is arranged at the bottom of the movable plate 301. The knocking mechanism includes a knocking rod 406, and the knocking rod 406 is used to knock the first filter screen 203. The knocking rod 406 is slidably connected to the movable plate 301. The knocking mechanism also includes a rotating structure, and the rotating structure is used to make the knocking rod 406 reciprocate and rise and fall. An alarm mechanism is installed on the tank body 101.

[0030] In this embodiment, the pressure-bearing component includes a slide rod 303, which is connected to the bottom of the movable plate 301 by bolts. A mounting plate 304 is slidably connected to the slide rod 303, and the mounting plate 304 is connected to the inner wall of the tank body 101 by bolts. A spring 305 is installed between the movable plate 301 and the mounting plate 304. The setting of the spring 305 can enable the movable plate 301 to change its height according to the amount of chemical raw materials carried on the second filter screen 302. When the second filter screen 302 is blocked and the passing efficiency of the chemical raw materials is reduced, the chemical raw materials retained on the second filter screen 302 will increase, thereby causing the movable plate 301 to drop.

[0031] In this embodiment, the alarm mechanism includes a warning light 501, which is fixedly mounted on the outside of the tank body 101. A trigger switch 502 is connected to the inside of the tank body 101 by bolts. The trigger switch 502 is arranged directly below a sliding rod 303. A connecting line 503 is arranged between the trigger switch 502 and the warning light 501. The warning light 501 includes a battery assembly. When the trigger switch 502 is triggered, it is electrically connected to the warning light 501 through the connecting line 503, and the signal is transmitted from the trigger switch 502 to the warning light 501. After the movable plate 301 is lowered to a certain extent, the staff sees the warning light 501 light up and cleans and maintains the second filter 302 in time.

[0032] In this embodiment, the knocking mechanism includes a motor 401, which is connected to the bottom of the movable plate 301 by bolts. The output end of the motor 401 is connected to the rotating structure. The rotating structure includes several groups of turntables 402. An eccentric rod 403 is connected between each group of turntables 402 by bolts. A connecting shaft 404 is connected between two adjacent groups of turntables 402 by bolts. A movable frame 405 is connected to the bottom of the knocking rod 406 by bolts. The movable frame 405 is sleeved on the eccentric rod 403. When the motor 401 is started, the output end of the motor 401 drives the turntable 402, the eccentric rod 403 and the connecting shaft 404 to rotate. The setting of the eccentric rod 403 enables the movable frame 405 and the knocking rod 406 to move back and forth in the up and down directions, knocking the first filter 203 to make the first filter 203 vibrate.

[0033] In this embodiment, the first filtering mechanism includes a collection box 205, which is connected to one side of the tank body 101 by bolts. A closed door 206 is rotatably installed on the collection box 205. The collection box 205 is set on the outside of the fixed plate 201. The staff regularly opens the closed door 206 to remove large particles in the collection box 205.

[0034] In this embodiment, the feed hopper 102 is arranged obliquely, and the first filter screen 203 is inclined in the opposite direction to the feed hopper 102. Such an arrangement allows the feed hopper 102 to fall into the high place of the first filter screen 203, thereby ensuring the filtering effect of the chemical raw materials. An inclined surface 306 is arranged on the inner side of the movable plate 301. The arrangement of the inclined surface 306 allows the chemical raw materials falling from the first filter screen 203 to fall onto the second filter screen 302.

[0035] In this embodiment, a closure plug 103 is detachably connected to one side of the tank body 101 . The closure plug 103 is installed on the tank body 101 via quick-release bolts. The components inside the tank body 101 can be maintained, cleaned and replaced by opening the closure plug 103 .

[0036] Working principle: When the device is in use, the chemical raw materials to be filtered are put into the tank body 101 from the feed hopper 102, and the motor 401 is turned on. The chemical raw materials flow to the first filter screen 203. As the chemical raw materials flow from the high place of the first filter screen 203 to the low place, the first filter screen 203 performs preliminary filtration on the chemical raw materials. After that, they flow from the first filter screen 203 to the second filter screen 302 for fine filtration. After reaching the filtration standard, they flow from the discharge port 104 to the collecting device (not shown in the figure). During the filtration process, the output end of the motor 401 drives the turntable 402, the eccentric rod 403 and the connecting shaft 404 to rotate. The setting of the eccentric rod 403 enables the movable frame 405 and the knocking rod 406 to reciprocate in the up and down directions, knocking the first filter screen 203 to make the first filter screen 203 vibrate. The vibration of the first filter screen 203 can accelerate the flow filtration rate of the chemical raw materials on the first filter screen 203, and also accelerate the process of the filtered material moving to the collection box 205, thereby improving the filtration efficiency of the chemical raw materials. The processing efficiency of the first filter 203 for chemical raw materials is improved. As the filtering amount increases, the second filter 302 processes more chemical raw materials, and the filtered impurities will accumulate on the second filter 302, causing a certain degree of accumulation, affecting the second filtration rate of the chemical substances, thereby increasing the weight of the movable plate 301 and the load, and the movable plate 301 presses the slide bar 303 to descend, and the spring 305 is compressed. At this time, the motor 401 also descends, and the knocking force of the knocking rod 406 on the first filter 203 will decrease, reducing the processing efficiency of the first filter 203. The flow and filtration efficiency of the chemical raw materials on the first filter 203 also decrease, preventing the second filter 302 from being subjected to excessive pressure. As the processing amount is further increased, the slide bar 303 descends to the trigger switch 502 position, and the trigger switch 502 lights up the prompt light 501 through the connecting line 503, reminding the staff to suspend the feeding and open the closing plug 103 to clean or replace the second filter 302.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
