Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation, and specifically to a solid-liquid separation device. Background Technology

[0002] Solid-liquid separation equipment is a mechanical device used to separate solid particles from liquids. It is widely used in wastewater treatment, mining, chemical industry, food processing, pharmaceuticals and other fields.

[0003] Common solid-liquid separation technologies include: Filtration: Separating solid particles from liquid using filter media (such as filter cloth or filter screen). Common equipment includes plate and frame filter presses, belt filters, and vacuum filters. Centrifugation: Separating solid particles from liquid using centrifugal force. Common equipment includes centrifuges and hydrocyclones. Sedimentation: Separating solid particles from liquid using gravity. Common equipment includes sedimentation tanks and clarifiers. Pressing: Forcing liquid out of solid particles using mechanical pressure. Common equipment includes screw presses and plate and frame presses. Membrane separation: Separating solid particles from liquid using semi-permeable membranes. Common equipment includes ultrafiltration membranes and microfiltration membranes.

[0004] In the existing technology, centrifuges are mainly composed of a cylindrical upper shell and a conical lower shell, which are connected and fixed by flanges and screws. Since the flange surfaces are all opened with annular array-shaped through holes, it is convenient for screws to pass through and fix the flanges. When the flanges at one end of the upper and lower shells are attached together, they cannot be quickly positioned, making it difficult for the through holes on the flange surfaces to be quickly aligned. It is necessary to manually move the upper or lower shell repeatedly for adjustment, which is time-consuming and labor-intensive.

[0005] Therefore, it is necessary to invent a solid-liquid separation device. Utility Model Content

[0006] The purpose of this invention is to solve the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a solid-liquid separation device, comprising an upper shell and a lower shell, wherein the lower shell is installed at one end of the upper shell, a drain outlet is provided at the end of the lower shell away from the upper shell, a water inlet is provided on the side of the upper shell away from the lower shell, and a water outlet is provided at the end of the upper shell near the water inlet, and a sealing ring and a hexagonal screw are connected between the upper shell and the lower shell.

[0008] Based on the above features: the upper and lower shells are locked together by hexagonal screws, and a sealing ring is provided between them to prevent gaps from causing liquid leakage after connection. Liquid containing particulate impurities is injected into the lower shell at high speed from the inlet under certain pressure. The liquid forms a downward spiral motion in the lower shell, generating a strong vortex. At this time, solid particles in the liquid splash down the inner wall of the lower shell under the action of centrifugal force, and settle down along the inner wall under the action of gravity and liquid flow, and finally discharged through the drain. The separated clean liquid forms a vortex at the bottom of the lower shell and is finally discharged through the outlet, achieving efficient separation of dirty liquid and cleaning liquid.

[0009] Preferably, a flange A is welded to the outside of the upper housing near the lower housing, and a first boss and a second boss are fixedly installed on the inner wall of the upper housing near the flange A, wherein the diameter of the first boss is larger than that of the second boss.

[0010] Based on the above features: the upper housing is connected to the lower housing via flange A, and the first and second bosses can be quickly positioned when the upper and lower housings are connected.

[0011] Preferably, a positioning protrusion is mounted on the surface of the second protrusion.

[0012] Based on the above features: the second boss uses a positioning bump to position the lower housing, and when the upper housing and the lower housing are attached together, the upper housing and the lower housing will not rotate or shift on their own.

[0013] Preferably, a flange B is fixedly installed on the outside of the lower housing near the upper housing, and an annular insert plate is installed on the lower housing away from the drain outlet. Lugs are provided on both sides of the flange B, and a connecting hole is provided in the middle of the lugs to facilitate the connection of the lugs with other equipment.

[0014] Based on the above features: both flange A and flange B have annular array-shaped through holes on their surfaces, which facilitates the use of hexagonal screws to fix them. The sealing ring is fitted on the outside of the annular insert plate. When the lower housing is inserted into one end of the upper housing using the annular insert plate, one end of the annular insert plate will fit against the surface of the second boss, and the sealing ring on the surface of the annular insert plate will be pressed against the inner wall of the first boss, which improves the positioning effect and enhances the sealing effect.

[0015] Preferably, the annular insert plate has a positioning hole at the end away from the lower housing.

[0016] Based on the above features: when one end of the annular insert plate is in contact with the surface of the second boss, the positioning protrusion on the surface of the second boss can be inserted into the positioning hole on the surface of the annular insert plate for rapid positioning.

[0017] Preferably, the lower housing has a conical structure.

[0018] Based on the above characteristics, it is convenient for the liquid to form a downward spiral motion inside the lower shell of the conical structure, generating a strong vortex.

[0019] Preferably, the water inlet has a circular structure and is arranged along the tangential direction.

[0020] Based on the above characteristics: it is used to inject liquid containing solid particles into the lower shell at high speed tangentially.

[0021] The beneficial effects of this utility model are:

[0022] 1. When flange B at one end of the lower housing is fitted with flange A at one end of the upper housing, the lower housing will use an annular insert plate to insert into the inner cavity of one end of the upper housing. At this time, one end of the annular insert plate will fit against the surface of the second boss, and the positioning protrusion on the surface of the second boss can be inserted into the positioning hole on the surface of the annular insert plate for quick positioning, so as to avoid the upper housing and the lower housing from shifting and causing the through holes on the surfaces of flange A and flange B to be misaligned.

[0023] 2. The inlet is set along the tangential direction to inject liquid containing solid particles into the lower shell at high speed. The sealing ring is fitted on the outside of the annular insert plate. When one end of the annular insert plate is in contact with the surface of the second boss, the sealing ring on the surface of the annular insert plate will be pressed by the inner wall of the first boss, making it difficult for the sealing ring to fall off the annular insert plate and enhancing the sealing effect.

[0031] The upper shell 1 and the lower shell 2 are locked together by hexagonal screws 7, and a sealing ring 6 is provided between them to prevent gaps from causing liquid leakage after the connection. Under a certain pressure, the liquid containing particulate impurities is injected into the lower shell 2 at high speed from the inlet 4. The liquid forms a spiral motion from top to bottom in the lower shell 2, generating a strong vortex. At this time, the solid particles in the liquid splash down the inner wall of the lower shell 2 under the action of centrifugal force, and settle down along the inner wall under the action of gravity and liquid flow, and finally discharged through the drain 3. The separated clean liquid forms a vortex at the bottom of the lower shell 2 and is finally discharged through the outlet 5, realizing the efficient separation of dirty liquid and cleaning liquid.

[0032] Preferably, a flange A11 is welded to the outside of the upper housing 1 near the lower housing 2, and a first boss 12 and a second boss 13 are fixedly installed on the inner wall of the upper housing 1 near the flange A11, with the diameter of the first boss 12 being larger than that of the second boss 13.

[0033] The upper housing 1 is connected to the lower housing 2 via flange A11, and the first boss 12 and the second boss 13 can be quickly positioned when the upper housing 1 and the lower housing 2 are connected.

[0034] Preferably, a positioning protrusion 131 is mounted on the surface of the second protrusion 13.

[0035] The second boss 13 uses the positioning boss 131 to position the lower housing 2. When the upper housing 1 and the lower housing 2 are attached together, the upper housing 1 and the lower housing 2 will not rotate or shift on their own.

[0036] Preferably, a flange B21 is fixedly installed on the outside of the lower housing 2 near the upper housing 1, and an annular insert plate 22 is installed on the lower housing 2 away from the drain port 3. Lugs 23 are provided on both sides of the flange B21, and a connection hole 24 is provided in the middle of the lugs 23 to facilitate the connection of the lugs 23 with other equipment through the connection hole 24.

[0037] The lower housing 2 is connected to the upper housing 1 by flange B21 and flange A11 at one end. Both flange A11 and flange B21 have annular array-shaped through holes on their surfaces to facilitate the penetration and fixation of hexagonal screws 7. The sealing ring 6 is fitted on the outside of the annular insert plate 22. After the lower housing 2 is inserted into the interior of one end of the upper housing 1 by the annular insert plate 22, one end of the annular insert plate 22 will fit against the surface of the second boss 13, and the sealing ring 6 on the surface of the annular insert plate 22 will be pressed against the inner wall of the first boss 12, which improves the positioning effect and enhances the sealing effect.

[0038] Preferably, the annular insert plate 22 has a positioning hole 221 at the end away from the lower housing 2.

[0039] When one end of the annular insert plate 22 is in contact with the surface of the second boss 13, the positioning protrusion 131 on the surface of the second boss 13 can be inserted into the positioning hole 221 on the surface of the annular insert plate 22 for quick positioning.

[0043] It is used to inject liquid containing solid particles into the lower shell 2 at high speed tangentially, and has the advantages of simple structure, stable operation and convenient maintenance.

[0044] The usage process of this utility model is as follows: Under a certain pressure, the liquid containing particulate impurities is injected into the lower housing 2 at high speed along the tangential direction through the inlet 4. Since the lower housing 2 is a conical structure, the liquid will form a spiral motion from top to bottom in the lower housing 2, generating a strong vortex. At this time, the solid particles in the liquid splash down the inner wall of the lower housing 2 under the action of centrifugal force, and settle down along the inner wall under the action of gravity and liquid flow, and finally be discharged through the drain outlet 3. The separated clean liquid forms a vortex at the bottom of the lower housing 2 and is finally discharged through the outlet 5.
