Description

Technical Field

[0001] This utility model belongs to the technical field of filtration devices, specifically, it relates to a filtration device for the production of feed additives. Background Technology

[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. They are used in very small quantities but have significant effects. Feed additives are essential raw materials in the modern feed industry, and they have obvious effects on enhancing the nutritional value of basic feed, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products. In the feed additive production process, filtration devices are essential equipment. Their main function is to remove impurities and harmful substances from the feed additive solution through physical methods. However, existing filtration devices have simple structures and single functions. When too much feed additive solution is injected, impurities can clog the filter screen during continuous filtration, reducing filtration efficiency and ultimately affecting the production efficiency of feed additives. Application number CN202323193415.9 discloses a filtration device for feed additive production. The device uses a transmission block to drive a transmission ring frame to move up and down repeatedly, which in turn causes the transmission ring frame to drive the filter screen to shake up and down repeatedly via a transmission rod, increasing the rate at which the solution passes through the filter screen and thus improving filtration efficiency. However, since the filter screen is horizontally structured, the filtered impurities remain on the screen, still affecting the filtration effect. In addition, the feed additive solution falls directly from the feed pipe, causing the solution to concentrate in a localized area of ​​the filter screen, making it more prone to localized filter screen blockage.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a filtration device for feed additive production. The basic concept of the technical solution adopted by this utility model to solve the above-mentioned technical problem is as follows:

[0005] A filtration device for feed additive production includes a filter cylinder and an upper sealing cover. A filter screen is installed inside the filter cylinder. The upper end of the filter screen is fixedly connected to a lower sliding rod. The upper end of the lower sliding rod is fixedly connected to a lifting and lowering plate. An upper sliding rod is fixedly installed on the upper end of the lifting and lowering plate. An upper sliding seat and a lower sliding seat are both provided on the outer side of the upper sliding rod and the lower sliding rod, respectively. A lifting and lowering groove is provided on the lifting and lowering plate, with an arc-shaped structure in the middle. A guide shaft is installed inside the lifting and lowering groove and is fixedly mounted on a rotating disk. The rotating disk is mounted on the main shaft of a drive motor. The filter screen has a conical structure. A folded impurity receiving groove is provided on the lower outer side of the filter screen. An inlet pipe is provided on the upper sealing cover, and the lower end of the inlet pipe is connected to a liquid distribution pipe to prevent the liquid from concentrating in a localized area.

[0006] As a further embodiment of this utility model: an upper housing is fixedly provided on the upper sealing cover, the drive motor is fixedly installed on the outside of the upper housing, and a bearing seat and bearing are provided at the mating position between the main shaft of the drive motor and the upper housing to ensure the stability of the rotating disk during rotation.

[0007] As a further improvement of this utility model: the liquid distribution pipe is a double-ring pipe structure, the double-ring pipes are interconnected, and multiple liquid outlet holes are evenly distributed along the circumference at the bottom of the liquid distribution pipe, so that the liquid falls from different positions.

[0008] As a further improvement of this utility model, the folded edge of the impurity receiving groove is provided with an arc-shaped edge at the position where it contacts the inner wall of the filter cylinder, which is beneficial to the stability of the filter screen lifting and adjusting.

[0009] As a further embodiment of this utility model: the upper sliding mating seat is fixed to the top position of the upper housing by an L-shaped bracket, and the lower sliding mating seat is fixed to the upper sealing cover by an L-shaped bracket. Both the upper sliding mating seat and the lower sliding mating seat are provided with corresponding sliding mating grooves for effectively limiting the lifting adjustment of the lifting mating plate.

[0010] As a further improvement of this utility model: the shape and specifications of the sliding groove are adapted to the shape and specifications of the upper sliding rod and the lower sliding rod, and the arc-shaped structure of the lifting and lowering sliding groove makes the lifting and lowering adjustment smooth.

The lower outer part of the filter screen is provided with a folded impurity collection groove, which can effectively collect the filtered impurities. At the same time, the filter screen can move back and forth under the action of the lifting and lowering plate, further reducing the probability of impurities clogging the mesh.

[0014] This invention features a liquid distribution pipe connected to the lower end of the feed pipe. The liquid distribution pipe has a double-ring structure and an outlet hole at the bottom, which allows the feed additive solution to fall at different positions on the filter screen, thus avoiding concentrated filtration.

[0028] The liquid distribution pipe 5 has a double-ring pipe structure, with the two ring pipes connected to each other. Multiple liquid outlet holes 18 are evenly distributed along the circumference at the bottom of the liquid distribution pipe 5 so that the liquid falls from different positions.

[0029] The impurity receiving tank 3 has an arc-shaped edge 19 at the position where the folded edge contacts the inner wall of the filter cylinder 1, which is beneficial to the stability of the lifting and lowering adjustment of the filter screen 2.

[0030] The upper sliding mating seat 11 is fixed to the top of the upper housing 7 by an L-shaped bracket, and the lower sliding mating seat 12 is fixed to the upper sealing cover 4 by an L-shaped bracket. Both the upper sliding mating seat 11 and the lower sliding mating seat 12 are provided with corresponding sliding mating grooves 20 for effectively limiting the lifting adjustment of the lifting mating plate 15.
