Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separator technology, and in particular to a discharge control mechanism and a solid-liquid separator. Background Technology

[0002] Chinese patent document CN217293677U, published on August 26, 2022, discloses a shearing discharge control mechanism and a solid-liquid separator with the shearing discharge control mechanism. The shearing discharge control mechanism includes a limiting ring fixed to a rotating shaft. A compression spring and a discharge control plate are fitted onto the rotating shaft. The compression spring presses the discharge control plate against the discharge port of the solid-liquid separator. The discharge control plate has shearing ribs on its back, which shear the solid material at the discharge port. Its advantages include rapid unloading and improved equipment applicability. Its disadvantage is that, combined with the appendix in CN217293677U… Figure 1 And the appendix to this application Figure 1 The limiting ring is fixed to the rotating shaft 30 by screws 51. When it is necessary to increase the pressure of the discharge control ring 40, the limiting ring needs to be moved to compress the spring 41. Since the spring 41 has a large elastic force, it is inconvenient to move and adjust the limiting ring to adjust the pressure of the discharge control ring 40 in actual use. Therefore, our company's technicians have improved the discharge control mechanism of the existing solid-liquid separator. Utility Model Content

[0003] The purpose of this utility model is to provide a discharge control mechanism and a solid-liquid separator. By setting an elongated hole on the rotating shaft, a limiting member is movably inserted into the elongated hole, and the screw is threadedly connected to the rotating shaft. By rotating the screw, the spring can be compressed or released, thereby facilitating the adjustment of the discharge control ring pressure.

[0004] To achieve the above objectives, this utility model provides a discharge control mechanism, including a bracket, a discharge control ring, a spring, and a limiting structure.

[0027] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0028] Example 1:

[0029] Please see Figure 1 A discharge control mechanism includes a bracket 20, a discharge control ring 40, a spring 41, and a limiting structure 50. The bracket 20 includes a mounting ring 21, a connecting rod 22, and a support ring 23. The mounting ring 21 is used to install onto the discharge port 11 side of the solid-liquid separator 10. The support ring 23 is connected and fixedly supported to the mounting ring 21 by at least two connecting rods 22. One end of the rotating shaft 30 of the solid-liquid separator 10 is mounted on the support ring 23 through a bearing 31. The discharge control ring 40 and the spring 41 are fitted onto the rotating shaft 30. The discharge control ring 40 is located on the discharge port 11 side. The limiting structure 50 is installed on the rotating shaft 30. One end of the spring 41 abuts against the discharge control ring 40, and the other end abuts against the limiting structure 50.

[0030] See Figure 2-5 The rotating shaft 30 is provided with a through-hole 32, which is arranged axially and passes through radially. The limiting structure 50 includes a limiting member 52 and a screw 60. The limiting member 52 is movably inserted into the through-hole 32. The screw 60 is threadedly connected to one end of the rotating shaft 30 located at the support ring 23. The screw 60 abuts against the limiting member 52, which is used to compress the spring 41.

[0031] By setting an elongated hole 32 on the rotating shaft 30, the limiting member 52 can be moved into the elongated hole 32. The screw 60 is threadedly connected to the rotating shaft 30. By rotating the screw 60, the limiting member 52 can be pushed to compress the spring 41, or the screw 60 can be rotated in the opposite direction to release the spring 41, thereby making it easy to adjust the pressure of the discharge control ring 40.

[0032] Specifically, in this embodiment, see Figure 2 , 4 The limiting member 52 is a rod or block structure, and it abuts against the spring 41. The limiting member 52 passes through the elongated hole 32, and both ends of the limiting member 52 extend out of the rotating shaft 30. The screw 60 can be an external hexagon or an internal hexagon screw, which facilitates tightening the screw 60 with a corresponding wrench.

[0033] Example 2:

[0034] Based on Embodiment 1, the limiting structure 50 also includes a movable ring 53, which is fitted onto the rotating shaft 30. One side of the movable ring 53 abuts against the spring 41 and the other side abuts against the limiting member 52.

[0035] In this embodiment, the screw 60 abuts against the limiting member 52, the limiting member 52 abuts against the movable ring 53, and the movable ring 53 abuts against the spring 41, thereby making the force-bearing area of ​​the spring 41 larger and the compression of the spring 41 more balanced and stable.

[0036] Example 3:

[0037] Based on Example 1, see Figure 3 , 5 The limiting structure 50 also includes a movable ring 53, which is fitted onto the rotating shaft 30. The movable ring 53 has a radially penetrating hole, and the limiting member 52 passes through this hole. The movable ring 53 abuts against the spring 41. Since the limiting member 52 directly abuts against one side of the movable ring 53, with the same spring 41 length, the length of the connecting rod 22 needs to be increased to increase the distance between the mounting ring 21 and the support ring 23, which would require modification of the bracket 20. However, the above structure makes the structure more compact, eliminating the need to modify the bracket 20.

[0038] Example 4:

[0039] Based on Example 1, 2, or 3, see [link to example]. Figure 2 , 3 The limiting member 52 has a first groove 521 at the position where it abuts against the screw 60, and the screw 60 extends into the first groove 521. The limiting member 52 can be positioned by the first groove 521 to prevent the limiting member 52 from falling off.

[0040] Example 5:

[0041] Based on embodiment 1, 2, 3, or 4, a nut 62 is installed at the end of the screw 60 located on the rotating shaft 30. After rotating the adjusting screw 60, the nut 62 is tightened to prevent the screw 60 from loosening. When it is necessary to rotate the screw 60, the nut 62 needs to be loosened first, especially when compressing the spring 41, so that the nut 62 is spaced a distance from the end of the rotating shaft 30.

[0042] Example 6:

[0043] Based on Example 1, 2, 3, 4, or 5, see [link to example]. Figure 2 , 3 A rotating handle 61 is installed at the end of the screw 60 that extends out of the rotating shaft 30. The handle 61 facilitates rotation of the screw 60. The handle 61 can be a circular handwheel, connected to the shaft end of the screw 60 via a keyway. Alternatively, the handle 61 can be an L-shaped crank structure, with a polygonal column on one side of the outer side of the screw 60. The L-shaped crank structure fits the polygonal column and facilitates disassembly.

[0044] Example 7:

[0045] Based on embodiments 1, 2, 3, 4, 5, or 6, this utility model also provides a solid-liquid separator, wherein the discharge control mechanism is installed on one side of the discharge port 11 of the solid-liquid separator 10.

[0046] The working principle or operation process of this utility model is as follows:

[0047] When using this product, if it is necessary to adjust the pressure of the discharge control ring 40, please refer to [the relevant documentation]. Figure 2 , 4 By rotating the screw 60 using the handle 61, when the screw 60 rotates in the tightening direction (i.e., moves to the left), the screw 60 presses against the limiting member 52, which compresses the spring 41, thereby increasing the pressure on the discharge control ring 40. When the handle 61 rotates the screw 60 in the opposite direction (i.e., moves to the right), the spring 41 extends, pushing the limiting member 52 to the right. Since the pressure on the spring 41 is released, the pressure on the discharge control ring 40 is reduced. After adjustment, tighten the nut 62 without rotating the screw 60.
