Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of sewage treatment, in particular to a novel solid-liquid separation device. Background Art
[0002] In the process of environmental protection, horizontal screw centrifuges are usually used to separate solids from liquids in sewage. Horizontal screw centrifuges use the combined action of centrifugal force and magnetic force to separate solids from liquids. The drum is equipped with a magnetic device that attracts the magnetic particles in the suspension. A small amount of paramagnetic material is used as a magnetic seed. In a strong magnetic field, heterogeneous coagulation can occur and the cotton wool agglomerates are paramagnetic. They can be separated in a high-gradient magnetic field. The magnetic particles are accelerated to settle on the inner wall of the drum by the combined action of gravity and magnetic force. The solid phase is transported to the slag outlet by the spiral, thereby achieving solid-liquid separation. It is particularly suitable for the separation of extremely fine magnetic particles.
[0003] When the existing horizontal screw centrifuge is in use, the separated solid phase is easy to adhere to the inner wall of the cavity, so the centrifuge needs to be cleaned frequently. The traditional cleaning method is generally to remove the drum and then take out the screw propeller for cleaning. The existing cleaning component mainly uses a nozzle to spray water to clean the inside of the centrifuge. However, during cleaning, the separated solids will adhere to the inner wall of the cavity, which is difficult to remove using a nozzle, and the nozzle will affect the operation of the horizontal screw centrifuge. In order to solve this problem, we propose a new solid-liquid separation device. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0025] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.
[0026] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0027] When the horizontal screw centrifuge is working, the drum and the screw rotate at high speed in the same direction with a certain differential speed. The material is continuously introduced into the inner cylinder of the feeding screw from the feed pipe, and enters the drum after acceleration. Under the action of the centrifugal field, the heavier solid phase is deposited on the drum wall to form a sediment layer. The feeding screw continuously pushes the deposited solid phase to the cone end of the drum and discharges it out of the machine through the slag discharge port. The lighter liquid phase forms an inner liquid ring, which continuously overflows the drum from the overflow port at the large end of the drum and is discharged out of the machine through the liquid discharge port.
[0028] In the related art, since the separated solid phase is easy to adhere to the inner wall of the cavity, the centrifuge needs to be cleaned frequently. The traditional cleaning method is generally to remove the drum and then take out the screw propeller for cleaning. The existing cleaning components mainly use a nozzle to spray water to clean the inside of the centrifuge. However, during cleaning, the separated solids will adhere to the inner wall of the cavity, which is difficult to remove using a nozzle, and the nozzle will affect the operation of the horizontal screw centrifuge.
[0029] In order to solve the problems in the related art to a certain extent, the embodiment of the present application provides a new solid-liquid separation device. When it is needed, it is only necessary to control the sewage to enter the cavity 12 from the feed port 16, turn on the motor 13 to control the rotation of the drum 14, and under the action of centrifugal force, the solids and liquids in the sewage are slowly separated, and the separated solid and liquid substances are discharged from different outlets respectively. During the separation process, the solids are sticky and will stick to the inner wall of the cavity 12. The user removes the fixed cover 241, and then controls the electric telescopic rod 22 to drive the water storage The plate 221 and the nozzle 222 descend into the interface 24, and the water pump 23 is turned on. The water pump 23 draws water from the water tank 231 through the water pipe 232 and the water pump 23 into the hose 233 and then into the water storage plate 221, and is sprayed out from the nozzle 222. The user then turns on the motor 13, and the motor 13 controls the rotation of the drum 14. The drum 14 drives the scraper 251 to rotate synchronously through the connecting rod 25. The scraper 251 scrapes and cleans the inside of the cavity 12, so that the adhered solids are scraped off and then discharged from the water outlet 26 along with the water flow, completing the cleaning process.
[0030] The present application is described below with reference to the accompanying drawings and specific embodiments:
[0031] Combination Figure 1-Figure 4, the embodiment of the present application provides that in order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new solid-liquid separation device, including a separation component 1; the separation component 1 includes: a cavity 12 is arranged inside a frame 11, a motor 13 is arranged on the frame 11, the output end of the motor 13 passes through the cavity 12 and is fixedly connected to a drum 14, a spiral pusher 15 is arranged on the drum 14, and a feed port 16 is arranged on the cavity 12; a cleaning component 2 is arranged on the separation component 1, and the cleaning component 2 includes: a fixed frame 21 is arranged on the frame 11, two electric telescopic rods 22 are arranged on the fixed frame 21, a water storage pan 221 is arranged at the bottom of the electric telescopic rod 22, and the A nozzle 222 is provided on the water storage tray 221; a water pump 23 is provided on the fixed frame 21, and the water pump 23 is connected to the water tank 231 through a water pipe 232, and the water pump 23 is connected to the water storage tray 221 through a hose 233; an interface 24 is provided on the cavity 12, and there are multiple interfaces 24, a connecting rod 25 is provided on the rotating drum 14, and the connecting rod 25 is fixedly connected to a scraper 251, a fixed cover 241 is provided on the interface 24, a fixed groove 242 is provided on the interface 24, a spring 243 is provided inside the fixed groove 242, the spring 243 and the plug rod 244 are fixedly connected, and the plug rod 244 and the interface 24 are plugged; a water outlet 26 is provided at the bottom of the cavity 12.
[0032] When it is needed, the sewage is controlled to enter the cavity 12 from the feed port 16, and the motor 13 is turned on to control the drum 14 to rotate. Under the action of centrifugal force, the solid and liquid in the sewage are slowly separated, and the separated solid and liquid substances are discharged from different outlets respectively. During the separation process, the solid has adhesiveness and will stick to the inner wall of the cavity 12. The user removes the fixed cover 241, and then controls the electric telescopic rod 22 to drive the water storage tray 221 and the nozzle 222 to descend and enter the interface 24. The water pump 23 is turned on. The water pump 23 draws water from the water tank 231 through the water pipe 232 and the water pump 23 into the hose 233 and then into the water storage tray 221, and is sprayed out from the nozzle 222. The user then turns on the motor 13. The motor 13 controls the drum 14 to rotate. The drum 14 drives the scraper 251 to rotate synchronously through the connecting rod 25.

[0033] Specifically, the fixed cover 241 can close the interface 24 when the separation component 1 is working to prevent the separated material from leaking from the interface. The user presses the plug rod 244 so that the plug rod 244 is pressed inward from the interface 24, compresses the spring 243, and releases the connection between the interface 24 and the plug rod 244.

[0035] In some embodiments, the diameter of the nozzle 222 is not larger than the size of the interface 24. The nozzle 222 is smaller in diameter than the interface 24 to ensure that the nozzle 222 can be inserted into the interface 24 without affecting the water output of the nozzle 222.
[0036] In some embodiments, a fixing cover 241 is disposed on the interface 24 , and a size of the fixing cover 241 is not smaller than a size of the interface 24 .
[0037] In some embodiments, the water outlet 26 is provided with a solenoid valve 261. When the solenoid valve 261 is powered on, the electromagnetic coil generates electromagnetic force to lift the closing member from the valve seat, the valve opens, and the cleaned sewage can flow out; when the power is off, the electromagnetic force disappears, the spring presses the closing member on the valve seat, and the valve closes.
