[0001] The utility model relates to the technical field of production filtering equipment, in particular to a filtering equipment for production. Background Art

[0002] In the process of chemical production, a large amount of raw materials need to be filtered before use. The main filtering core of the existing filtering equipment is the filter medium.

[0003] During use, the raw materials pass through the filter medium, and the internal impurities are adsorbed or blocked by the filter medium. After a period of use, the filter medium needs to be replaced or cleaned in time to avoid the decline of the filtering effect caused by the long-term use of the filter medium or the shortening of the service life of the filtering equipment due to the difficulty of the raw materials passing through the filtering equipment. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the following problems existing in the prior art:

[0005] During use, the raw materials pass through the filter medium, and the internal impurities are adsorbed or blocked by the filter medium. After a period of use, the filter medium needs to be replaced or cleaned in time to avoid the decline of the filtering effect caused by the long-term use of the filter medium or the shortening of the service life of the filtering equipment due to the difficulty of the raw materials passing through the filtering equipment.

[0006] To solve the problems existing in the prior art, the utility model provides a filtering equipment for production, including an outer tank body. A sieve column is arranged at the bottom of the inner wall of the outer tank body, an inner filter cylinder is arranged on the inner wall of the outer tank body, a sieve mesh is arranged at the bottom of the outer tank body, a feeding device is arranged at the top of the outer tank body, and a discharging device is arranged at the bottom of the outer tank body.

[0007] The utility model provides a filtering equipment for production.

[0008] Further, the outer tank body is a barrel-shaped structure with a cross-section in the shape of "H", and a flange structure adapted to the feeding device is arranged at the top.

[0009] Further, the inner filter cylinder is divided into a barrel-shaped part and an outer sleeve part. The barrel-shaped part is adapted to the inner wall of the outer tank body, and the outer sleeve part is sleeved outside the sieve column. The outer sleeve part is made of the filter medium.

[0010] Further, both the sieve column and the sieve mesh are of a fine mesh structure, and the mesh number of the sieve mesh is greater than that of the sieve column.

[0011] Further, the sieve column is arranged at the bottom of the inner wall of the "H"-shaped top opening of the outer tank body, and the sieve mesh is arranged on one side of the inner wall of the "H"-shaped bottom opening of the outer tank body.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] In the present utility model, raw materials are injected into the interior through the charging device arranged at the top of the outer tank. After the raw materials enter the outer tank, they fall into the inner filter cylinder. When a certain amount is injected, the pressure inside the outer tank increases. Under the action of the pressure, the raw materials pass through the inner filter cylinder and enter the inside of the screen column. During this process, the impurities in the raw materials stay on the surface of the inner filter cylinder, and the raw materials entering the screen column continue to flow and fall onto the surface of the screen for secondary sieving to ensure that the impurities inside are completely removed. Moreover, the impurities on the surface of the inner filter cylinder will slide down to the bottom under the flushing action of the raw materials and will not cover the part of the inner filter cylinder sleeved on the surface of the screen column, ensuring that the inner filter cylinder can always have a good filtering effect during long-term operation, extending the overall service life of the equipment. And when cleaning is required, the charging device can be disassembled through the flange, and the inner filter screen can be removed along the outer tank to clean the inner filter screen. The overall structure is convenient and fast, and the operation is simple. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific embodiments of the present utility model will be described below in conjunction with the accompanying drawings.

[0023] Embodiment 1

[0024] As Figures 1-4 shown, a filtering device for production includes an outer tank body 1. At the bottom of the inner wall of the outer tank body 1, a sieve column 2 is provided. An inner filter cylinder 3 is arranged on the inner wall of the outer tank body 1. The inner filter cylinder 3 is divided into a barrel part and an outer sleeve part. The barrel part is adapted to the inner wall of the outer tank body 1, and the outer sleeve part is sleeved outside the sieve column 2. The outer sleeve part is made of filter material. A sieve mesh 4 is arranged at the bottom of the outer tank body 1. Both the sieve column 2 and the sieve mesh 4 are of a fine mesh structure. The mesh number of the sieve mesh 4 is greater than that of the sieve column 2. The sieve column 2 is arranged at the bottom of the inner wall of the H-shaped top opening of the outer tank body 1, and the sieve mesh 4 is arranged on one side of the inner wall of the H-shaped bottom opening of the outer tank body 1. A feeding device 5 is arranged at the top of the outer tank body 1. The feeding device 5 includes a cover and a feeding pipe. A flange adapted to the outer tank body 1 is provided at the bottom of the cover and connecting bolts are provided. A feeding pipe is installed at the top of the cover. The outer tank body 1 is a barrel-shaped structure with an H-shaped cross-section, and a flange structure adapted to the feeding device 5 is arranged at the top. A discharging device 6 is arranged at the bottom of the outer tank body 1. The discharging device 6 is arranged at the H-shaped bottom opening of the outer tank body 1, and there is a gap between its inner wall and the sieve mesh 4.

[0025] Explanation of the working principle: First, the feeding device 5 arranged at the top of the outer tank body 1 injects raw materials into the outer tank body 1. After the raw materials enter the outer tank body 1, they fall into the inner filter cylinder 3. When a certain amount is injected, the pressure inside the outer tank body 1 increases. Under the action of the pressure, the raw materials pass through the inner filter cylinder 3 and enter the sieve column 2. In this process, the impurities in the raw materials stay on the surface of the inner filter cylinder 3. The raw materials entering the sieve column 2 continue to flow and fall onto the surface of the sieve mesh 4 for secondary sieving to ensure that the impurities inside are completely removed, and then are discharged outwards along the discharging device 6. The impurities on the surface of the inner filter cylinder 3 will slide down to the bottom under the scouring action of the raw materials and will not cover the part of the inner filter cylinder 3 sleeved on the sieve column 2;

[0026] When the inner filter cylinder 3 needs to be cleaned again, the feeding device 5 is disassembled through the flange, so that the inner filter cylinder 3 is exposed. The operator can take out the inner filter cylinder 3 along the inside of the outer tank body 1 for cleaning. After cleaning, place it back in place and install the feeding device 5 on the outer tank body 1 using the flange.

[0027] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
