Description

Technical Field

[0001] This application belongs to the field of auxiliary equipment for discharging materials from a washing tank, and specifically relates to a solid-liquid separation device for discharging materials from a washing tank. Background Technology

[0002] Water washing reactors are key equipment in the chemical, pharmaceutical, and new materials fields for material purification and impurity removal. Their core functions include post-reaction processing, phase transfer and neutralization, and cleaning of solid materials. The discharge from a water washing reactor typically contains both liquid and solid substances. For example, if the target product is a solid, separation is required after washing. Alternatively, unreacted raw materials or byproducts may precipitate due to decreased solubility during the washing process.

[0003] If the target product is a solid, solid-liquid separation of the discharge from the washing tank is the only way to obtain a qualified product. If the washing liquid discharged from the washing tank contains recyclable solvents, it can be distilled and reused after separation. If it is wastewater, solids must be separated before it can enter the wastewater treatment system.

[0004] In the existing technological system, precipitation separation and centrifugal separation are the two main separation technology routes: Precipitation separation, as the most basic separation method, suffers from the drawback of "relying on natural sedimentation without external reinforcement." However, its separation efficiency is extremely low, the cycle is lengthy, and it requires a large area, resulting in high space costs. After sedimentation, the bottom solids need to be manually removed or mechanically scraped off. The process can easily introduce external impurities, making it particularly unsuitable for fields with high cleanliness requirements, such as pharmaceuticals and food.

[0005] Centrifugal separation equipment requires high investment and consumes a lot of energy. The purchase cost of a single LW355 horizontal screw centrifuge is about 100,000 to 150,000 yuan, with a matching motor power of 8-15kW and a daily energy consumption of about 192-360kW. The annual electricity cost exceeds 100,000 yuan; and additional buffer tanks and feed pumps are required, making the overall equipment investment 1.5-2 times that of the washing tank itself. Utility Model Content

[0006] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide a solid-liquid separation device for discharging water from a washing tank. This application integrates the discharging of water from the washing tank and the solid-liquid separation simultaneously, which greatly optimizes the efficiency, cost and reliability of the separation process.

[0007] The technical solution adopted by this application to solve its existing problems is: A solid-liquid separation device for discharging materials from a washing vessel includes a shell and a filter assembly.

[0008] The housing includes a filter chamber, a liquid inlet channel that runs through the upper part of the filter chamber, and a liquid outlet channel and a solid outlet channel that run through the lower part of the filter chamber. The liquid outlet channel is located directly below the liquid inlet channel.

[0009] The filter assembly is rotatably mounted inside the filter chamber and is driven by a motor fixed outside the housing.

[0010] Preferably, the filter chamber is cylindrical, and the filter assembly includes a first rotating shaft and a plurality of filter plates arranged in a ring array around the axis of the first rotating shaft, with the end face of the filter plate abutting against the inner wall of the filter chamber.

[0011] The first rotating shaft end extends through the outside of the housing and is connected to the motor output shaft.

[0012] Preferably, the liquid discharge channel and the solid discharge channel are arranged in parallel and spaced apart.

[0013] Preferably, the liquid discharge channel and the solid discharge channel are respectively located on both sides of the first rotating shaft axis.

[0014] Preferably, the filter chamber has a groove recessed on its inner wall located between the liquid discharge channel and the solid discharge channel.

[0015] The housing is provided with a striking assembly, which includes a striking plate and a reset mechanism. The striking plate is rotatably disposed inside the groove.

[0016] In the initial state, the striking plate is arranged vertically with its top surface located outside the groove. The reset mechanism causes the striking plate to reset when it rotates.

[0017] Preferably, the striking plate has a second rotating shaft protruding from its end, the second rotating shaft is rotatably connected to the housing, and a torsion spring is provided between the second rotating shaft and the housing.

[0018] Preferably, the end of the second rotating shaft extends to the outside of the housing, and a sleeve is fitted on the second rotating shaft located outside the housing, with a fixing key inserted between the sleeve and the second rotating shaft.

[0019] The outer shell is fixed with a mounting bracket, the mounting bracket is recessed with a slot, and the sleeve is provided with an insertion hole.

[0020] The torsion spring is sleeved on the sleeve, and its two ends are respectively inserted into the insertion hole and the slot.

[0021] Compared with the prior art, the beneficial effects of this application are as follows: (1) The liquid inlet channel of the shell is directly connected to the discharge port of the washing tank. When the mixture enters the filter chamber, the liquid-solid separation is completed simultaneously by the rotating filter plate. The liquid goes directly into the liquid discharge channel, and the solid is transferred to the solid discharge channel with the filter plate. The discharge of the washing tank and the solid-liquid separation are carried out simultaneously. There is no need to discharge the liquid-solid mixture from the washing tank first and then transfer it to equipment such as centrifuge for subsequent separation. This reduces intermediate links, shortens the overall production cycle, and avoids material loss or pollution that may occur during the transfer process.

[0022] (2) The servo motor drives the filter plate ring array to rotate. The rotation speed can be adjusted to adapt to different discharge volumes, so as to achieve continuous separation of "how much is fed in and how much is separated", without batch waiting time, and ensure the continuity of separation.

[0023] (3) When the filter plate rotates to the end of the solid discharge channel, it will collide with the striking plate and generate vibration. Combined with the automatic striking mechanism of the torsion spring reset, it can thoroughly remove the solids adhering to the filter plate, avoid filter hole blockage and solid residue, and always maintain stable filtration efficiency.

[0024] (4) The separation function of this solution is integrated into the discharge path. It only requires a compact structure such as shell, filter assembly, and impact assembly. There is no need to purchase additional large separation equipment, which greatly reduces equipment investment and floor space.

[0025] (5) The striking assembly adopts a simple mechanical structure such as torsion springs and sleeves, without complex electronic components. During subsequent maintenance, only the wear of the filter plate or the elasticity of the torsion spring needs to be checked. The operation and maintenance cost is far lower than that of the centrifugal separator used for solid-liquid separation in the existing technology. Attached Figure Description

Detailed Implementation

[0029] The attached figure shows the preferred embodiment of the solid-liquid separation device for discharging material from a water washing kettle. The following is a more detailed description of this application in conjunction with the attached figure.

[0030] Depend on Figures 1 to 9 As shown, a solid-liquid separation device for discharging material from a washing vessel includes a housing 1 and a filter assembly.

[0031] The housing 1 includes a filter chamber 101, a liquid inlet channel 102 that is connected through the upper part of the filter chamber 101, and a liquid outlet channel 103 and a solid outlet channel 104 that are connected through the lower part of the filter chamber 101. The liquid outlet channel 103 is correspondingly disposed directly below the liquid inlet channel 102.

[0032] In this embodiment, the filter chamber 101 is cylindrical, and the liquid discharge channel 103 and the solid discharge channel 104 are arranged in parallel and spaced apart. The liquid discharge channel 103 and the solid discharge channel 104 are respectively located on both sides of the axis of the filter chamber 101.

[0033] The filter assembly is rotatably disposed inside the filter chamber 101 and is driven by a motor 4 fixed outside the housing 1.

[0034] In this embodiment, the filter assembly includes a first rotating shaft 2 and a plurality of filter plates 3 arranged in a circular array around the axis of the first rotating shaft 2. The end face of the filter plate 3 abuts against the inner wall of the filter cavity 101. The end of the first rotating shaft 2 extends to the outside of the housing 1 and is connected to the output shaft of the motor 4.

[0035] Motor 4 is a servo motor. Figure 3 The upward arrows indicate the direction of liquid flow and the rotation direction of filter plate 3, respectively. Figure 3 As shown, the motor 4 drives the filter plate 3 to rotate in the direction of liquid inlet in the liquid inlet channel 102, so that... Figure 3Taking the arrangement direction as an example, the liquid inlet channel 102 is arranged on the left side of the filter chamber 101. The discharge direction of the water washing kettle is from top to bottom. When the filter plate 3 rotates clockwise, the liquid in the solid-liquid mixture discharged into the filter chamber 101 by the liquid inlet channel 102 flows downward through the filter holes on the filter plate 3 into the liquid discharge channel 103. The solid matter is intercepted by the filter plate 3. Then, with the filter plate 3, until the filter plate 3 rotates to the other side of the filter chamber 101, and then tilts downward, the solid matter slides downward under the action of gravity and slides into the solid discharge channel 104.

[0036] To prevent solids from sticking to the filter plate 3 and from slipping off when the filter plate 3 is in a vertical position, the filter plate 3 rotates back into the liquid discharge channel 103. In this embodiment, the housing 1 is provided with a knocking assembly, which knocks on the filter plate 3 when it is about to leave the solid discharge channel 104, thereby vibrating and cleaning it, so that all the solids attached to the filter plate 3 fall into the solid discharge channel 104.

[0037] Therefore, in this embodiment, the inner wall of the filter chamber 101 located between the liquid discharge channel 103 and the solid discharge channel 104 is recessed with a groove 105.

[0038] The striking assembly includes a striking plate 5 and a reset mechanism, wherein the striking plate 5 is rotatably disposed inside the groove 105; In the initial state, the striking plate 5 is arranged vertically, with the upper surface of the front end of the striking plate 5 located outside the groove 105 and extending above the solid discharge channel 104.

[0039] The reset mechanism causes the striking plate 5 to reset when it rotates. In this embodiment, the reset mechanism is a torsion spring 8.

[0040] The bottom end face of the striking plate 5 is provided with a second rotating shaft 501, which is rotatably connected to the housing 1, and a torsion spring 8 is provided between the second rotating shaft 501 and the housing 1.

[0041] To increase the outer diameter of the second rotating shaft 501 for easier connection with the torsion spring 8, the end of the second rotating shaft 501 extends to the outside of the housing 1. A sleeve 6 is fitted onto the second rotating shaft 501 located outside the housing 1, and a fixing key 7 is inserted between the sleeve 6 and the second rotating shaft 501. The fixing key 7 fixes the sleeve 6 and the second rotating shaft 501 in a fixed connection.

[0042] The housing 1 is externally fixed with a mounting bracket 9, which has a recessed slot 901. The sleeve 6 has an insertion hole 601. The torsion spring 8 is sleeved on the sleeve 6, with its two ends inserted into the insertion hole 601 and the slot 901, respectively.

[0043] When the filter plate 3 rotates to the end of the solid discharge channel 104, it collides with the striking plate 5. The striking plate 5 strikes the filter plate 3, and the solids on the filter plate 3 fall off and into the solid discharge channel 104 through vibration.

[0044] The filter plate 3 continues to rotate, overcoming the torque of the torsion spring 8, and pushing the striking plate 5 to rotate along the axis of the second rotating shaft 501 until the striking plate 5 rotates into the groove 105. After the filter plate 3 rotates past the groove 105, the striking plate 5 rotates in the opposite direction to reset under the action of the torsion spring 8. The rotation speed of the filter plate 3 is adjusted by the motor 4 so that when the striking plate 5 rotates in the opposite direction to the end, it collides with the next filter plate 3, thus optimizing the striking and discharge effect on the filter plate 3.

[0045] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application.
