Description

Technical Field

[0001] The utility model relates to the technical field of screw pumps, in particular to a screw pump which is easy to clean. Background Art

[0002] The screw pump is a positive displacement rotor pump that relies on the volume change of the sealed chamber formed by the screw and the bushing to suck in and discharge the liquid. The characteristics of the screw pump are stable flow, small pressure pulsation, self-priming ability, low noise, high efficiency, long life and reliable operation. Its outstanding advantage is that it does not form eddy currents when conveying the medium, is insensitive to the viscosity of the medium, and can convey high-viscosity media.

[0003] For example, the Chinese patent number CN215979862U is a kind of anti-blocking screw pump. When the utility model is working, the motor is turned on, and the motor drives the rotating shaft and the driven rod to rotate. The material enters from the feed hopper, is first crushed by the crushing knife, and then filtered through the filter screen, so that the smaller material enters the pump body and is not easy to block the pump body. Under the action of the rotating shaft and the spiral blades, the material is discharged from the output end of the pump body. When the filter screen needs to be cleaned, the motor and the drain valve are turned off, and the cleaning liquid is injected from the liquid inlet. The waste water generated during cleaning is discharged by opening the drain valve on the drain pipe at the bottom of the pump body. However, this cleaning method cannot remove the larger material above the filter screen, so the larger material above the filter screen will always be above the filter screen. Therefore, a screw pump that is easy to clean is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a screw pump that is easy to clean and has the advantage of removing larger materials above the filter screen, thereby solving the problem that the larger materials above the filter screen cannot be removed.

[0005] To achieve the above object, the utility model provides the following technical solution: a screw pump that is easy to clean, comprising a screw pump body, a feed hopper is arranged above the screw pump body, a closing mechanism is arranged inside and outside the feed hopper, a filtering mechanism is connected to one side of the closing mechanism, and a supporting mechanism is arranged inside the feed hopper;

[0006] The closing mechanism comprises a baffle, the baffle is located inside the feed hopper, a sealing strip is connected to one side of the baffle, and a handle is connected to one side of the baffle;

[0007] The filtering mechanism comprises a filtering basket, the filtering basket is located on one side of the closing mechanism, and a filtering net is connected to the interior of the filtering basket;

[0008] The supporting mechanism comprises a first supporting rod and a second supporting rod, and the first supporting rod and the second supporting rod are both located inside the feed hopper.

[0009] Furthermore, the sealing strip is located above the baffle, and the handle is located outside the feed hopper.

[0010] Furthermore, the baffle and the sealing strip are both plugged into the feed hopper, and the filtering mechanism is located inside the feed hopper.

[0011] Furthermore, the filter basket is in a U-shape, and the filter net is in a cone shape.

[0012] Furthermore, the filter screen is connected to the bottom end of the filter basket, and the first supporting rod and the second supporting rod are staggered and connected at 90 degrees.

[0013] Furthermore, the supporting mechanism is located below the filtering mechanism, and the first supporting rod and the second supporting rod are both connected to the inner wall of the feed hopper.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] 1. The screw pump, which is easy to clean, can prevent overflow through baffles and sealing strips. The filter basket can temporarily store larger materials intercepted by the filter net. The filter net is conical, so not only the filtering surface is large, but also the filter net can be prevented from being completely covered by too much larger materials. Larger materials can be intercepted by the filter net. The supporting mechanism is located below the filter mechanism, and the first supporting rod and the second supporting rod play a supporting role on the filter mechanism.

[0016] 2. The screw pump, which is easy to clean, is filtered by the filtering mechanism so that materials with smaller volumes can enter the interior of the screw pump body, which is not easy to clog the screw pump body. Under the action of the rotating shaft and the spiral blades, the materials are discharged from the output end of the screw pump body. When the filtering mechanism needs to be cleaned, the motor and the drain valve are turned off, the filtering mechanism is moved out of the feed hopper, and after pouring out the larger materials in the filter basket, the filtering mechanism is inserted into the interior of the feed hopper, so it is easy to remove the larger materials in the filtering mechanism.

[0028] See also Figure 4-5The filtering mechanism 4 is located inside the feed hopper 2, and the filtering basket 401 is in the shape of a U-shaped figure. The filtering basket 401 can temporarily store larger materials intercepted by the filtering net 402. The filtering net 402 is in the shape of a cone, so not only the filtering surface is large, but also the filtering net 402 can be prevented from being completely covered by too much larger materials.

[0030] When implementing, follow these steps:

[0031] 1) First turn on the motor, the motor drives the rotating shaft and the driven rod to rotate, the material enters from the feed hopper 2, and is crushed by the crushing knife;

[0032] 2) Then the material is filtered by the filtering mechanism 4, so that the material with a smaller volume enters the interior of the screw pump body 1, and is not easy to block the screw pump body 1. Under the action of the rotating shaft and the spiral blades, the material is discharged from the output end of the screw pump body 1;

[0033] 3) When the filter mechanism 4 needs to be cleaned, turn off the motor and the drain valve, move the filter mechanism 4 out of the feed hopper 2, pour out the larger materials in the filter basket 401, and then insert the filter mechanism 4 into the feed hopper 2;

[0036] In addition, the motor is turned on first, and the motor drives the rotating shaft and the driven rod to rotate. The material enters from the feed hopper 2, is crushed by the crushing knife, and then is filtered by the filtering mechanism 4, so that the smaller material enters the interior of the screw pump body 1, and is not easy to block the screw pump body 1. Under the action of the rotating shaft and the spiral blades, the material is discharged from the output end of the screw pump body 1. When it is necessary to clean the filtering mechanism 4, the motor and the drain valve are turned off, the filtering mechanism 4 is moved out of the feed hopper 2, and after pouring out the larger material in the filter basket 401, the filtering mechanism 4 is inserted into the interior of the feed hopper 2, and finally the cleaning liquid is injected from the feed hopper 2. The waste water generated during cleaning is discharged through the drain pipe, which solves the problem of not being able to remove the larger material above the filter screen.
