Description

Technical Field

[0001] This utility model belongs to the field of centrifuge technology, and in particular relates to a solid-liquid separation device for centrifuges. Background Technology

[0002] Lithium hydroxide monohydrate contains one water molecule, which forms a water film on the crystal surface. Under external force, the crystals approach and come into contact, and the saturated lithium hydroxide liquid films of the two crystals connect, forming a shared liquid film at the point of contact. Under certain temperature conditions, as the storage time increases, the water in the liquid film gradually evaporates. When the lithium hydroxide in the liquid film reaches saturation, it crystallizes out, and the resulting small lithium hydroxide monohydrate crystals connect with the original two crystals. Most of the crystals connect with each other, thus forming agglomerates.

[0003] Based on the aforementioned characteristics of lithium hydroxide monohydrate, during the production process of lithium hydroxide monohydrate, clumps are easily formed inside the feed pipe of the centrifuge. This can cause the feed rate of the centrifuge to gradually decrease or even become blocked, thereby affecting the centrifuge's production capacity.

[0004] Therefore, the feed pipe of the centrifuge is often rinsed during the production process. However, the rinsing water can enter the product through the feed pipe, thus affecting the product quality. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a solid-liquid separation device for centrifuges, which can rinse the feed pipe and prevent the product quality from being affected by the rinsing water entering the product.

[0006] The objective of this utility model is achieved through the following technical solution:

[0007] A solid-liquid separation device for a centrifuge, comprising:

[0008] The box has a first discharge pipe at the top for connecting to the discharge end of the centrifuge, and a discharge pipe and a water outlet pipe at the bottom.

[0009] The second feeding pipe has its inlet end rotatably connected to the box body and located directly below the first feeding pipe.

[0010] The drive assembly is connected to the housing and is used to drive the discharge end of the second discharge pipe to rotate directly above the discharge pipe and directly above the water outlet pipe.

[0011] The beneficial effects of adopting the above technical solution are as follows: the drive component can drive the discharge end of the second discharge pipe to rotate directly above the discharge pipe, so that the material separated by the centrifuge passes through the first and second discharge pipes in sequence and enters the discharge pipe, thereby completing the discharge process; the drive component can also drive the discharge end of the second discharge pipe to rotate directly above the water outlet pipe, so that the water separated by the centrifuge or the water supplied externally enters the first and second discharge pipes in sequence, thereby rinsing the first and second discharge pipes, and the rinsing water during the rinsing process will enter the water outlet pipe and be discharged, thereby avoiding the impact on product quality due to the rinsing water entering the product from the discharge pipe.

[0012] Furthermore, the drive assembly includes a linear drive mechanism and a connecting rod. The fixed end of the linear drive mechanism is hinged to the outside of the housing, and the output end of the linear drive mechanism is hinged to one end of the connecting rod.

[0013] The drive assembly includes a connecting shaft rotatably connected to the side wall of the housing, the inner end of the connecting shaft being fixedly connected to the feed end of the second feed pipe, and the outer end of the connecting shaft being fixedly connected to the other end of the connecting rod.

[0014] The beneficial effects of adopting the above technical solution are as follows: when the linear drive mechanism outputs, the output end of the linear drive mechanism extends out, the linear drive mechanism swings around the hinge point with the outside of the box, and at the same time the connecting rod rotates around the axis of the connecting shaft, thereby driving the second feeding pipe to rotate around the axis of the connecting shaft, and thus causing the discharge end of the second feeding pipe to rotate to the top of the discharge pipe or the top of the water outlet pipe.

[0015] Furthermore, an overflow pipe is connected to one side of the outlet pipe.

[0016] The beneficial effects of adopting the above technical solution are as follows: This configuration allows the flushing water to be discharged through the overflow pipe when the water outlet pipe becomes clogged, thereby preventing the flushing water from overflowing into the tank or the discharge pipe.

[0017] Furthermore, an observation tube is connected to one side of the discharge pipe.

[0018] The beneficial effects of adopting the above technical solution are as follows: This setting makes it convenient to observe the material feeding situation using the observation tube, thereby facilitating timely cleaning when material accumulates in the discharge tube.

[0019] Furthermore, the observation tube is set at an angle, and its lower end is connected to the discharge tube.

[0020] The beneficial effects of adopting the above technical solution are as follows: this setting makes it difficult for materials to leak out of the observation tube, thereby ensuring that all materials are discharged from the discharge tube.

[0021] Furthermore, the lower two sides of the box are connected to the discharge pipe and the water discharge pipe, respectively.

[0022] Furthermore, a cleaning hole is provided on one side of the box, and a plate for sealing the cleaning hole is detachably connected to the box.

[0023] The beneficial effects of adopting the above technical solution are: this setting makes it convenient for cleaning personnel to clean the inside of the box through the cleaning hole after removing the panel.

[0024] Furthermore, the plate body is screwed to the outside of the housing.

[0025] The beneficial effect of adopting the above technical solution is that this setting facilitates the removal of the panel from the outside of the box.

[0026] Furthermore, the top of the box is open, and a lid is detachably connected to the top of the box.

[0027] The beneficial effects of adopting the above technical solution are: this setting makes it convenient for cleaning personnel to clean the materials inside the box after removing the box cover.

[0028] Furthermore, the first feed pipe is fixedly connected to the box cover.

[0029] The beneficial effects of this utility model are as follows:

[0030] The drive assembly can drive the discharge end of the second discharge pipe to rotate directly above the water outlet pipe, so that the water separated by the centrifuge or the water supplied from the outside can enter the first discharge pipe and the second discharge pipe in sequence, thereby rinsing the first discharge pipe and the second discharge pipe. The rinsing water will enter the water outlet pipe and be discharged, thus avoiding the impact on product quality due to the rinsing water entering the product from the discharge pipe.

[0037] The present invention will be further described below with reference to the accompanying drawings.

[0038] This utility model provides a solid-liquid separation device for centrifuges, such as... Figure 1 As shown, it includes:

[0039] Box 1, with a first discharge pipe 2 vertically arranged at the upper end of the box 1 for connecting to the discharge end of the centrifuge, and a discharge pipe 6 and a water outlet pipe 7 arranged at the lower end of the box 1;

[0040] The second feeding pipe 4 has its inlet end rotatably connected inside the housing 1 and located directly below the first feeding pipe 2.

[0041] Drive assembly 3 is connected to housing 1. Drive assembly 3 is used to drive the discharge end of the second discharge pipe 4 to rotate directly above the discharge pipe 6 and directly above the water outlet pipe 7.

[0042] Understandably, the drive assembly 3 can drive the discharge end of the second discharge pipe 4 to rotate directly above the discharge pipe 6, so that the material separated by the centrifuge passes through the first discharge pipe 2 and the second discharge pipe 4 in sequence and enters the discharge pipe 6, thereby completing the discharge process; the drive assembly 3 can also drive the discharge end of the second discharge pipe 4 to rotate directly above the water outlet pipe 7, so that the water separated by the centrifuge or the water supplied externally enters the first discharge pipe 2 and the second discharge pipe 4 in sequence, thereby rinsing the discharge pipes of the first discharge pipe 2 and the second discharge pipe 4, and the rinsing water during the rinsing process will enter the water outlet pipe 7 and be discharged, thereby avoiding the impact on product quality due to the rinsing water entering the product from the discharge pipe 6.

[0043] It should be noted that after the centrifuge dehydrates the material, a scraper can be used to scrape off the material adhering to the centrifuge.

[0044] In one embodiment, the drive assembly 3 includes a linear drive mechanism 301 and a connecting rod 302. The fixed end of the linear drive mechanism 301 is hinged to the outside of the housing 1, and the output end of the linear drive mechanism 301 is hinged to one end of the connecting rod 302.

[0045] The drive assembly 3 includes a connecting shaft 303 rotatably connected to the side wall of the housing 1. The inner end of the connecting shaft 303 is fixedly connected to the feed end of the second feed pipe 4, and the outer end of the connecting shaft 303 is fixedly connected to the other end of the connecting rod 302.

[0046] It is understandable that when the linear drive mechanism 301 outputs, the output end of the linear drive mechanism 301 extends out, the linear drive mechanism 301 swings around the hinge point with the outside of the housing 1, and at the same time the connecting rod 302 rotates around the axis of the connecting shaft 303, thereby driving the second feeding pipe 4 to rotate around the axis of the connecting shaft 303, and thus causing the discharge end of the second feeding pipe 4 to rotate to the position directly above the discharge pipe 6 or the water outlet pipe 7.

[0047] It should be noted that the linear drive mechanism 301 can be a cylinder, a hydraulic cylinder or an electric push rod. A mounting bracket can be fixedly connected to the outside of the housing 1. One end of the cylinder of the linear drive mechanism 301 can be hinged to the mounting bracket. One end of the rod of the linear drive mechanism 301 is hinged to one end of the connecting rod 302.

[0048] In one embodiment, an overflow pipe 8 is connected to one side of the water outlet pipe 7 so that the flushing water can be discharged through the overflow pipe 8 when the water outlet pipe 7 is blocked, thereby preventing the flushing water from overflowing into the tank 1 or the discharge pipe 6.

[0049] It should be noted that the overflow pipe 8 is preferably connected to the upper middle part of the water outlet pipe 7, so as to prevent the lower part of the water outlet pipe 7 from being blocked and causing the flushing water to overflow into the tank 1 or the discharge pipe 6.

[0050] In one embodiment, an observation tube 5 is connected to one side of the discharge pipe 6 to facilitate observation of the material discharge situation, thereby facilitating timely cleaning when material accumulates in the discharge pipe 6.

[0051] It should be noted that the overflow pipe 8 can be set on the side of the water outlet pipe 7 away from the discharge pipe 6, and the observation pipe 5 can be set on the side of the discharge pipe 6 away from the water outlet pipe 7.

[0052] In one embodiment, the observation tube 5 is inclined and the lower end of the observation tube 5 is connected to the discharge tube 6. That is, the material needs to overcome the effect of gravity to leak out of the observation tube 5, so that the material is difficult to leak out of the observation tube 5, thereby ensuring that the material is discharged from the discharge tube 6.

[0053] In one embodiment, the lower ends of the housing 1 are connected to the discharge pipe 6 and the water discharge pipe 7, respectively.

[0054] In one embodiment, a cleaning hole 9 is provided on one side of the housing 1, and a plate for sealing the cleaning hole 9 is detachably connected to the housing 1 so that cleaning personnel can remove the plate and clean the inside of the housing 1 through the cleaning hole 9.

[0055] In one embodiment, the plate is screwed to the outside of the housing 1 to facilitate removal of the plate from the outside of the housing 1.

[0056] In one embodiment, the upper end of the box 1 is open, and the upper end of the box 1 is connected to the box cover by a flange and bolts, so as to facilitate the cleaning personnel to clean the materials inside the box 1 after removing the box cover; the first discharge pipe 2 is welded to the box cover.
