[0022] The embodiments of the present invention are described in detail below, and 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 be used to explain the present invention, but cannot be understood as limiting the present invention.

[0023] Reference below Figure 1-Figure 3 A horizontal vibrating centrifuge according to an embodiment of the present invention is described.

[0024] like Figure 1-Figure 3 As shown, the horizontal vibrating centrifuge of the embodiment of the utility model includes a screen basket 1 and a feed pipe 2.

[0025] The screen basket 1 has a small end and a large end which are arranged opposite to each other along the axial direction of the screen basket 1, and the cross-sectional area of ​​the small end is smaller than the cross-sectional area of ​​the large end. The feed pipe 2 is arranged at one side of the small end of the screen basket 1, and the outlet of the feed pipe 2 is connected to the screen basket 1 and is arranged along the tangential direction of the screen basket 1.

[0026] Specifically, Figure 1 As shown, the sieve basket 1 is arranged along the left-right direction, and the cross-section of the sieve basket 1 increases from left to right, so that the left end of the sieve basket 1 forms a small end, and the right end of the sieve basket 1 forms a large end, and the cross-sectional area of ​​the small end is smaller than the cross-sectional area of ​​the large end. In other words, the diameter of the small end is larger than the diameter of the large end.

[0027] The feed pipe 2 is arranged on the left side of the screen basket 1, the outlet of the feed pipe 2 is connected to the screen basket 1, and the opening direction of the outlet of the feed pipe 2 is arranged along the tangent direction of the screen basket 1. Preferably, the feed pipe 2 is arranged along the tangent direction of the screen basket 1.

[0028] The horizontal vibrating centrifuge of the utility model embodiment arranges the feed pipe on one side of the small end of the screen basket, and the outlet of the feed pipe is arranged along the tangent direction of the screen basket. The material enters the small end of the screen basket through the feed pipe, so that the dehydration process and the feeding process of the material do not interfere with each other, and the material is prevented from colliding with the feed pipe during the dehydration process to cause the material to be over-crushed, and the operating efficiency of the horizontal vibrating centrifuge can be improved, and the disassembly and assembly of the feed pipe and the screen basket is also convenient.

[0029] At the same time, the material has a certain tangential speed under the guidance of the feed pipe, which can further improve the centrifugal effect and the operating effect of the horizontal vibrating centrifuge. The moving direction of the material after entering the screen basket from the small end is consistent with the vibration direction of the screen basket, both are along the axial direction of the screen basket, which can also improve the operating effect of the horizontal vibrating centrifuge and reduce the impact of the material on the screen basket.

[0030] Further, such as Figure 1 As shown, the horizontal vibrating centrifuge of the utility model embodiment also includes a material guide chamber 3, which is arranged on the small end side of the screen basket 1 and extends along the axial direction of the screen basket 1. In other words, the material guide chamber 3 is arranged on the left side of the screen basket 1 and extends in the left-right direction.

[0031] The small end of the screen basket 1 is provided with a feed inlet, specifically, the small end of the screen basket 1 is open to form the feed inlet. The right end of the material guide chamber 3 is open so that the inner cavity of the material guide chamber 3 is communicated with the feed inlet.

[0032] The feed pipe 2 is arranged on the material guiding chamber 3 .

[0033] The guide chamber 3 connects the feed pipe 2 with the small end of the screen basket 1 and plays a role in transferring materials. The material enters the guide chamber 3 from the feed pipe 2 and maintains a tangential speed along the screen basket 1 in the guide chamber 3, and then enters the small end of the screen basket 1 through the guidance of the guide chamber 3. At the same time, the guide chamber 3 also plays a role in evenly distributing the material in the screen basket 1 to avoid uneven entry of the material into the screen basket 1, which may cause the screen basket 1 and the horizontal vibrating centrifuge to be unbalanced and shaken.

[0034] Preferably, the cross section of the material guide chamber 3 is annular around the axial direction of the screen basket 1, in other words, the material guide chamber 3 is cylindrical along the left-right direction, so as to ensure that the material maintains a certain tangential velocity through the inner circumference of the material guide chamber 3.

[0035] The right end of the material guide chamber 3 is open and connected to the feed inlet so that the material in the material guide chamber 3 evenly enters the small end of the screen basket 1. More preferably, the diameter of the material guide chamber 3 is consistent with the diameter of the small end of the screen basket 1 to ensure smooth movement of the material.

[0036] The left end of the material guiding chamber 3 is closed to prevent the material in the material guiding chamber 3 from escaping from the left end of the material guiding chamber 3 .

[0037] The feed pipe 2 is arranged on the circumferential wall of the guide chamber 3 and is arranged tangentially of the guide chamber 3. Under the action of the material height difference and the guidance of the feed pipe 2, the material enters the guide chamber 3 with a certain tangential speed, thereby generating a greater centrifugal force when entering the screen basket 1 to improve the dehydration effect.

[0038] Furthermore, the material guiding chamber 3 is sealedly connected to the small end of the screen basket 1 .

The metal sealing ring is hard-sealed to the right end face of the material guide chamber 3. Preferably, the right end face of the material guide chamber 3 is provided with an annular protrusion, which extends circumferentially along the material guide chamber 3. The left end face of the metal sealing ring is provided with an annular groove, which extends circumferentially along the metal sealing ring.
