Description

Technical Field

[0001] This utility model relates to the field of chemical additive production technology, specifically to an automatic anti-precipitation filtration device for chemical additive production. Background Technology

[0002] Chemical auxiliaries are a class of fine chemicals added during chemical production processes. They have small molecular weights but strong functionalities, primarily used to improve product performance, optimize production processes, or impart specific functions to products. During temporary storage, the solid particles in chemical auxiliaries may gradually settle due to gravity, leading to stratification, clumping, and other phenomena that disrupt uniformity. This not only affects the accuracy of auxiliary dosage in subsequent production but may also cause pipe blockages and equipment wear due to sediment accumulation, increasing the risk of production failures. Filtration aims to remove impurities from materials. If these impurities enter the production process, they may trigger abnormal chemical reactions, product appearance defects, or functional failures.

[0003] In the field of chemical additive production, storage tanks are key equipment for temporary storage, mixing, and preliminary filtration of materials. Currently, most chemical additive storage tanks use a built-in fixed filter structure to intercept impurities in the materials to ensure product purity. The filter is usually fixedly connected to the tank body, making it difficult to disassemble and maintain. During long-term use, impurities easily clog the filter pores, leading to a significant decrease in filtration efficiency. If the filter needs to be cleaned, operators often have to risk entering the tank, facing safety risks such as oxygen deficiency and poisoning from working in a confined space, and the cramped operating environment makes cleaning extremely difficult. Although some storage tanks are equipped with removable filters, the disassembly structure is complex, requiring numerous tools and involving the disassembly and assembly of multiple parts, which is time-consuming, labor-intensive, increases downtime maintenance costs, and affects production continuity and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an automatic anti-precipitation filtration device for the production of chemical auxiliaries, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An automatic anti-precipitation filtration device for the production of chemical auxiliaries includes:

[0007] A storage tank is provided with a liquid inlet at the top, a slag outlet at the bottom, and a liquid outlet on the bottom side. A fixing ring is fixedly connected to the inner wall of the storage tank, a fixing column is fixedly connected to the upper end face of the fixing ring, and a first filter screen is installed above the fixing ring.

[0008] A drive shaft, the top end of which is rotatably connected to the output end of a drive motor fixed at the top of the storage tank, the bottom of which passes through a through hole in the center of the first filter screen to the bottom of the storage tank, and a first stirring rod and a second stirring rod are fixedly connected to the outside of the drive shaft.

[0009] An installation port is provided above the liquid outlet, and a secondary filtration component is installed in the installation port for secondary filtration when discharging chemical additives.

[0013] Preferably, a handle is fixedly connected to the top of the sealing plate, the sealing plate and the handle are located inside the mounting opening, and a sealing cap is connected to the top of the mounting opening via a threaded connection.

[0014] Preferably, the internal space of the storage tank is divided into an upper tank and a lower tank, with the upper tank located above the first filter screen and the lower tank located below the first filter screen.

[0015] Preferably, the first stirring rod is located in the upper tank and the second stirring rod is located in the lower tank.

[0016] Preferably, the storage tank has a sealed upper lid on top of the tank body.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] In this invention, a first stirring rod and a second stirring rod are installed inside the tank to act on the upper and lower tanks respectively, continuously stirring the chemical additives and effectively preventing the materials from settling and stratifying during storage. The first filter screen can intercept larger particulate impurities, preliminarily filtering the materials flowing into the lower tank, improving the purity of the chemical additives, and ensuring the stability of subsequent production processes and product quality.

[0019] This invention, by setting up a secondary filtration component, utilizes the difference in pore size between the second and third filter screens to achieve further filtration of chemical additives. It can intercept fine impurities on the basis of the preliminary filtration of the first filter screen, reduce the impurity content of the output material, and improve the purity and quality stability of the chemical additives.

[0020] In this invention, the first, second, and third filter screens can all be easily removed, avoiding complex disassembly procedures and significantly reducing downtime for maintenance. After being removed from the tank, they can be thoroughly cleaned using methods such as high-pressure rinsing and soaking to completely remove impurities, effectively ensuring the filtration effect. At the same time, it reduces the labor intensity of operators, reduces safety hazards, lowers the cost of replacing consumables, and ensures the long-term efficient operation of the device.

[0027] 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.

[0028] Example 1:

[0029] Please see Figures 1 to 3 This utility model provides a technical solution:

[0030] An automatic anti-precipitation filtration device for the production of chemical auxiliaries includes:

[0031] Storage tank 1, the storage tank 1 is provided with a liquid inlet 3 at the top, a slag discharge port 4 at the bottom, and a liquid outlet 5 on the bottom side. A fixing ring 7 is fixedly connected to the inner wall of the storage tank 1, a fixing column 701 is fixedly connected to the upper end face of the fixing ring 7, and a first filter screen 8 is installed above the fixing ring 7.

[0032] The drive shaft 9 is rotatably connected at its top end to the output end of the drive motor 10 fixed at the top of the storage tank 1. The bottom of the drive shaft 9 passes through the through hole 802 in the center of the first filter screen 8 to reach the bottom of the storage tank 1. The first stirring rod 901 and the second stirring rod 902 are fixedly connected to the outside of the drive shaft 9.

[0033] Specifically, the internal space of the storage tank 1 is divided into an upper tank 101 and a lower tank 102. The upper tank 101 is located above the first filter screen 8, and the lower tank 102 is located below the first filter screen 8.

[0034] Specifically, a sealed bearing is provided between the drive motor 10 and the drive shaft 9, so that the drive shaft 9 can rotate continuously while ensuring sealing.

[0035] In this embodiment, the internal space of the storage tank 1 is divided into an upper tank 101 and a lower tank 102 by the first filter screen 8. The chemical additive is injected into the storage tank 1 through the liquid inlet 3. After the drive motor 10 is started, it drives the drive shaft 9 to rotate. The first stirring rod 901 located in the upper tank 101 rotates accordingly to stir the newly entered liquid material, avoid the rapid settling of solid particles, and maintain the uniform mixing state of the material.

[0036] As stirring proceeds, the liquid material flows into the lower tank 102 through the first filter screen 8. The first filter hole 801 on the first filter screen 8 can intercept larger particulate impurities, preventing them from entering the lower tank 102 and improving the quality of the chemical additives. Inside the lower tank 102, the second stirring rod 902 continues to stir the filtered chemical additives to further prevent sedimentation. When the chemical additives are needed, the liquid outlet 5 on the bottom side is opened, and the evenly mixed liquid material is discharged from the liquid outlet 5 into the subsequent process.

[0037] Specifically, the first stirring rod 901 is located inside the upper tank 101, and the second stirring rod 902 is located inside the lower tank 102.

[0038] Specifically, the upper tank body 101 of the storage tank 1 has a sealed upper tank cover 2, which can be sealed by conventional tank sealing methods such as bolts and sealing rings to ensure that the tank does not leak.

[0039] In this embodiment, the upper lid 2 of the storage tank 1 can be opened to remove the internal drive shaft 9. At the same time, the first filter screen 8 is inserted into the fixing post 701 on the fixing ring 7 fixed inside the tank through the mounting hole 803 on the edge for cleaning. After cleaning, the mounting hole 803 on the first filter screen 8 is aligned with the fixing post 701 and inserted again from above, so that it can be reinstalled and put into use. The whole process avoids complicated installation and disassembly procedures, reduces downtime for maintenance, and the first filter screen 8 can be removed for cleaning. Various deep cleaning methods such as high-pressure water gun washing and soaking in special cleaning agents can be used to thoroughly clean the impurities and deposits remaining on the first filter screen 8. The cleaning quality is far higher than cleaning the filter screen directly inside the tank.

[0040] Example 2:

[0041] Please see Figures 4 to 5 This utility model provides a technical solution that is basically the same as that in Embodiment 1, with slight differences:

[0042] An installation port 6 is provided above the liquid outlet 5, and a secondary filtration assembly is installed in the installation port 6 for secondary filtration when discharging chemical additives.

[0043] Specifically, the secondary filtration assembly includes a second filter screen 1102, which is fixedly connected to the lower end face of the sealing plate 1101, and a second filter hole 1103 is provided on the second filter screen 1102.

[0044] Specifically, the secondary filtration assembly also includes a third filter screen 1104, which is fixedly connected to the lower end face of the sealing plate 1101, and the third filter screen 1104 is provided with a third filter hole 1105.

[0045] Specifically, a connecting plate 1106 is fixedly connected between the bottom of the second filter screen 1102 and the third filter screen 1104 for storing filtered impurities.

[0046] Specifically, the diameter of the second filter hole 1103 of the second filter screen 1102 is larger than the diameter of the third filter hole 1105 of the third filter screen 1104 (e.g., Figure 4 ).

[0047] In this embodiment, the chemical additives that have undergone preliminary filtration by the first filter screen 8 are output through the liquid outlet 5. A secondary filtration assembly is installed inside the liquid outlet 5. The chemical additives first come into contact with the second filter screen 1102. Since the diameter of the second filter pores 1103 is relatively large, it allows the liquid after preliminary filtration to pass through. The chemical additives that have passed through the second filter screen 1102 continue to the third filter screen 1104. The diameter of the filter pores of the third filter screen 1104 is smaller, which can further trap residual fine particles and impurities. Under the combined action of gravity and liquid pressure, the trapped impurities gradually settle down to the connecting plate 1106 at the bottom of the second filter screen 1102 and the third filter screen 1104 for storage, which greatly reduces the impurity content of the chemical additives output from the liquid outlet 5, effectively improving the purity and quality stability of the product.

[0048] Specifically, a handle 11 is fixedly connected to the top of the sealing plate 1101, the sealing plate 1101 and the handle 11 are located inside the mounting port 6, and a sealing cover 601 is connected to the top of the mounting port 6 through a threaded connection part 602.

[0049] In this embodiment, after the storage tank 1 has been running for a period of time, the sealing cap 601 connected by threads above the installation port 6 can be unscrewed first. Then, the operator can hold the handle 11 fixedly connected above the sealing plate 1101 and pull it upwards to completely remove the sealing plate 1101 together with the second filter screen 1102, the third filter screen 1104 and the connecting plate 1106 fixed to its lower end face from the installation port 6. Use cleaning tools and cleaning agents to clean the impurities trapped on the second filter screen 1102, the third filter screen 1104 and the connecting plate 1106. After cleaning, align the secondary filter assembly with the installation port 6, press the sealing plate 1101 down into place using the handle 11, and finally tighten the sealing cap 601 to ensure that the installation port 6 is sealed. It can then be quickly put back into use.

[0050] Specifically, the second filter screen 1102 and the third filter screen 1104 are preferably made of rubber. The second filter hole 1103 and the third filter hole 1105 are directly opened on the second filter screen 1102 and the third filter screen 1104. The rubber material allows the second filter screen 1102 and the third filter screen 1104 to deform due to the elasticity of the rubber when inserted into the installation port 6, and pass smoothly through the installation port 6. When the filter screen is completely inserted into the internal space of the installation port 6, the rubber material, which has lost the external pressure, recovers its deformation due to its own elasticity, so that the edge of the filter screen fits tightly against the inner wall of the installation port 6, and filters the chemical additives that have passed through the liquid outlet 5. The second filter screen 1102 and the third filter screen 1104 have a certain thickness to prevent the chemical additives from being deformed by impact.

[0051] In use, the chemical additives are injected into the upper tank 101 through the liquid inlet 3 at the top of the storage tank 1. The drive motor 10 drives the drive shaft 9 and the first and second stirring rods 902 to rotate synchronously. The first stirring rod 901 stirs the material in the upper tank 101 to prevent particles from settling and to promote the liquid to flow through the first filter screen 8 into the lower tank 102. The first filter screen 8 initially filters out larger impurities. The second stirring rod 902 in the lower tank 102 continues to stir to maintain the uniformity of the material. When it is ready to be output, the chemical additives pass through the secondary filtration component in the liquid outlet 5, first through the second filter screen 1102, and then through the third filter screen 1104 to intercept fine impurities. The impurities settle into the connecting plate 1106 for storage, so that the chemical additives with higher purity are discharged from the liquid outlet 5 for subsequent processes. After working for a period of time, the upper tank cover 2 can be opened to quickly remove the first filter screen 8 for cleaning, and the secondary filtration component can be taken out through the installation port 6 to clean the second filter screen 1102 and the third filter screen 1104.

[0052] All other parts of this utility model not described herein are the same as existing technology or are known technology or can be implemented using existing technology, and will not be described in detail here.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
