DETAILED DESCRIPTION

[0023] In order to enable the above-mentioned purposes, features and advantages of the present application to be more clearly understood, the present application will be further described below with reference to the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0024] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be practiced without the specific details, which are different from the description herein, and therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0025] As shown in Figs. 1-3 The present application provides a replaceable screen size suspension agent filtering device, which comprises a funnel 100, a support 200 fixedly connected to the outer side of the funnel 100 and arranged in an array along the circumference of the funnel 100, a filter screen 300 arranged on the funnel 100, a fixed box 400 fixedly connected to the outer side of the funnel 100 and arranged symmetrically, a vertical rack 500 fixedly connected to the edge of the filter screen 300, and a fixing assembly 600 arranged in the fixed box 400, wherein the vertical rack 500 can be inserted into the corresponding fixed box 400 and limited by the fixing assembly 600.

[0026] In the present embodiment, the fixing assembly 600 comprises a rotating shaft 601 rotatably arranged in the fixed box 400, a gear 602 fixedly sleeved on the outer wall of the rotating shaft 601 and engageable with the vertical rack 500, and a through slot 603 formed in the fixed box 400 and through which the vertical rack 500 passes.

[0027] In the present embodiment, the rotating shaft 601 is fixedly sleeved with a ratchet wheel 604, a support shaft 605 is fixedly connected to the inner wall of the fixed box 400, a clamping jaw 606 cooperated with the ratchet wheel 604 is hinged to the support shaft 605, and a spring 607 is arranged between the top of the clamping jaw 606 and the inner wall of the fixed box 400.

[0028] In the present embodiment, an arc-shaped slot 608 with the support shaft 605 as the center is formed in the side surface of the fixed box 400, an adjusting pin 609 is fixedly connected to the side surface of the clamping jaw 606, and the end of the adjusting pin 609 away from the clamping jaw 606 penetrates through the arc-shaped slot 608. By controlling the sliding of the adjusting pin 609 in the arc-shaped slot 608, the clamping jaw 606 is deflected by the adjusting shaft to separate the clamping jaw 606 and the ratchet wheel 604, so that the ratchet wheel 604 is no longer limited.

[0029] In the present embodiment, a liquid discharge pipe 700 is fixedly connected to the bottom of the funnel 100, and a liquid discharge valve 800 is arranged in the liquid discharge pipe 700. By opening the liquid discharge valve 800, different volumes of materials can be discharged.

[0030] In this embodiment, the filter screen 300 can be selected with different mesh, and the filter screen 300 with different mesh can be replaced to filter different types of suspending agent materials.

[0031] In this embodiment, the filter screen 300 and the funnel 100 are both conical structures, which can effectively gather materials and improve the collection rate of the materials.

[0032] The use method and working principle of the device are as follows:

[0033] When the device is used, first, the filter screen 300 is placed in the funnel 100, and the vertical rack 500 is aligned with the through slot 603. With the placement of the filter screen 300, the vertical rack 500 is inserted into the through slot 603 and cooperates with the gear 602 to drive the gear 602 to rotate the rotating shaft 601. When the rotating shaft 601 rotates, the ratchet wheel 604 rotates and constantly pushes the clamping jaw 606 to press the spring 607. When the vertical rack 500 no longer moves, the clamping jaw 606 cooperates with the ratchet wheel 604 under the action of the spring 607 to limit the rotating shaft 601 and the gear 602 from being reversed, so that the vertical rack 500 cannot move upward, and the installation of the filter screen 300 is completed.

[0034] At this time, the suspending agent material to be filtered, including zirconium beads, is poured into the filter screen 300 together, and the material flows down from the filter screen 300 into the bottom of the funnel 100 by gravity, and the zirconium beads remain in the filter screen 300. A container for containing the material is placed under the liquid discharge pipe 700, and the liquid discharge valve 800 is opened to discharge the material, which can effectively avoid the splashing of the filtered material and pollution of the environment, and greatly improve the collection rate of the filtered material.

[0035] When filtering different types of suspending agent materials, the adjusting pin 609 is controlled to slide in the arc-shaped slot 608, the clamping jaw 606 is deflected by the adjusting shaft to separate the clamping jaw 606 and the ratchet wheel 604, the clamping jaw 606 no longer limits the ratchet wheel 604, the filter screen 300 is pulled upward to move the vertical rack 500 upward, and the above operation is repeated to replace the filter screen 300 with different mesh to filter different types of suspending agent materials. In addition, the device is convenient to disassemble, so that it is convenient to clean.

[0036] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields, but any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still belongs to the protection scope of the technical scheme of the present application.
