Description

Technical Field

[0001] This utility model belongs to the field of water return filtration technology, and in particular relates to a filtration and cleaning mechanism used at the inlet of a water return system. Background Technology

[0002] In a liquid return system, impurities accumulate to varying degrees during the processing of the liquid in the pipeline. These deposits can clog the pumping devices in the return system and affect the various processing reactions. While directly installing filters in the pipeline to filter impurities can lead to clogging of the filters over time, causing blockages in the return system, further complicates matters. Additionally, cleaning or replacing the filters in the return pipeline requires stopping the system's operation, thus impacting production.

[0003] To address these issues, we provide a filtration and cleaning mechanism for the inlet of a return water system. Utility Model Content

[0004] The purpose of this invention is to provide a filtration and cleaning mechanism for the inlet of a water return system. This mechanism involves rotating a centrifuge cylinder within a centrifugal component, which is then fitted onto the outside of the inlet funnel. A clear liquid ring groove is attached to the outside of the centrifuge cylinder. Rotating the centrifuge cylinder throws the input liquid into a centrifuge tube installed on the side wall of the cylinder. Under centrifugal force, the liquid separates into layers, allowing the less dense clear liquid to enter the clear liquid ring groove from the top of the centrifuge tube. This achieves the technical effect of separating impurities from the clear liquid. Furthermore, by attaching a filter residue ring groove to the lower end of the centrifuge tube, denser impurities settle and enter the filter residue ring groove as the centrifuge cylinder rotates, thus collecting the impurities. This avoids the problem of impurities accumulating in the pipeline and eliminates the need for frequent replacement and cleaning of the filter device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a filtration and cleaning mechanism for the inlet of a water return system, comprising a centrifugal component and a collection component. The centrifugal component includes an inlet funnel, a centrifugal cylinder, and a set of centrifugal tubes. The collection component includes a clear liquid ring groove and a filter residue ring groove. The inlet funnel is rotatably fitted onto the upper end of the centrifugal cylinder. The clear liquid ring groove is fitted onto the outside of the centrifugal cylinder. The filter residue ring groove is fitted onto the lower end of the centrifugal cylinder. A set of centrifugal channels is horizontally and circumferentially arrayed on the outer sidewall of the lower end of the centrifugal cylinder. The axis of the centrifugal channels is perpendicular to the axis of the centrifugal cylinder. The sidewalls of the set of centrifugal tubes are respectively fixedly connected to the end face of the centrifugal channels away from the centrifugal cylinder. The upper outlet end of the centrifugal tube extends into the clear liquid ring groove. An outlet pipe is fixed on one sidewall of the clear liquid ring groove. The lower sludge outlet end of the centrifugal tube extends into the filter residue ring groove.

[0007] The present invention is further configured such that the centrifuge tube gradually tilts towards the centrifuge cylinder from top to bottom, and a horizontal section is fixedly extended from the upper end of the centrifuge tube away from the centrifuge cylinder, and a vertical section is fixedly extended downward from the horizontal section, with the vertical section extending into the clear liquid ring groove.

[0008] The present invention is further configured such that a slag discharge section is fixedly provided at the lower end of the centrifuge tube extending vertically downward, and the slag discharge section extends into the filter residue ring groove.

[0009] The present invention is further configured such that an annular upper tray is fixedly installed at the lower end of the clear liquid annular groove, a set of vertical connecting columns are fixedly arranged in a circumferential array on the lower end plate surface of the annular upper tray, a support plate is fixedly installed at the lower end of the set of connecting columns, and the filter residue annular groove is fixedly installed on the upper plate surface of the support plate.

[0010] The present invention is further configured such that a vertical transmission rod is fixedly provided on the lower end face of the centrifuge cylinder, the transmission rod passes through the support plate, a motor sleeve is installed at the lower end of the support plate, a centrifugal motor is installed inside the motor sleeve, and the output end of the centrifugal motor is fixedly connected to the transmission rod.

[0011] The present invention is further configured such that a receiving component is installed on the pallet, and the receiving component is sleeved on the outside of the transmission rod.

[0012] The present invention is further configured such that the receiving component includes a receiving sleeve, a ball cover, and a set of balls.

A set of balls pass through the ball through holes.

[0013] This utility model has the following beneficial effects:

[0014] This invention achieves the technical effect of separating impurities from the clear liquid by rotating the centrifuge cylinder in the centrifugation component and attaching it to the outside of the liquid inlet funnel, and attaching a clear liquid ring groove to the outside of the centrifuge cylinder. The centrifuge cylinder is rotated to throw the input liquid into the centrifuge tube installed on the side wall of the centrifuge cylinder, and the liquid is separated into layers under the action of centrifugal force, so that the clear liquid with lower density enters the clear liquid ring groove from the top of the centrifuge tube.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0026] Please see Figures 1 to 3This utility model relates to a filtration and cleaning mechanism for the inlet of a water return system, comprising a centrifugal component 1 and a collecting component 2. The centrifugal component 1 includes an inlet funnel 101, a centrifugal cylinder 102, and a set of centrifugal tubes 103. The collecting component 2 includes a clear liquid ring groove 201 and a filter residue ring groove 202. By rotating the centrifugal cylinder 102 in the centrifugal component 1 to be sleeved on the outside of the inlet funnel 101, and by sleeved on the outside of the clear liquid ring groove 201, rotating the centrifugal cylinder 102 throws the input liquid onto the side wall of the centrifugal cylinder 102. In the centrifuge tube 103, under the action of centrifugal force, the liquid with lower density enters the clear liquid ring trough 301 from the upper end of the centrifuge tube 103, thus achieving the technical effect of separating the impurities from the clear liquid. By connecting the filter residue ring trough 202 to the lower end of the centrifuge tube 103, when the centrifuge tube 102 rotates, the impurities with higher density settle down and enter the filter residue ring trough 202, thus achieving the collection of impurities and avoiding the problem of impurities accumulating in the pipeline, eliminating the need for constant replacement and cleaning of the filter device.

[0027] Specifically, the inlet funnel 101 is rotatably sleeved on the upper end of the centrifuge cylinder 102, the clear liquid ring groove 201 is sleeved on the outside of the centrifuge cylinder 102, and the filter residue ring groove 202 is sleeved on the lower end of the centrifuge cylinder 102. A set of centrifuge channels 102a is fixedly arranged in a horizontal circumferential array on the outer side wall of the lower end of the centrifuge cylinder 102. The axis of the centrifuge channels 102a is perpendicular to the cylinder axis of the centrifuge cylinder 102. The side walls of a set of centrifuge tubes 103 are respectively fixedly connected to the end face of the centrifuge channels 102a away from the centrifuge cylinder 102. The upper liquid outlet end of the centrifuge tube 103 extends into the clear liquid ring groove 201. A liquid outlet 201a is fixedly provided on one side wall of the clear liquid ring groove 201. The lower residue outlet end of the centrifuge tube 103 extends into the filter residue ring groove 202.

[0028] Furthermore, the centrifuge tube 103 gradually tilts towards the centrifuge cylinder 102 from top to bottom. A horizontal section 103a is fixedly extended from the upper end of the centrifuge tube 103 away from the centrifuge cylinder 102. A vertical section 103b is fixedly extended downward from the horizontal section 103a. The vertical section 103b extends into the clear liquid ring tank 201. After the liquid enters the centrifuge tube 103, under the action of centrifugal force, the clear liquid with a lower density is discharged from the vertical section 103b at the upper end of the centrifuge tube 103 and enters the clear liquid ring tank 201.

[0029] Furthermore, the lower end of the centrifuge tube 103 is vertically extended downward and fixed with a slag discharge section 103c. The slag discharge section 103c extends into the filter residue ring groove 202. The impurities precipitated in the filter residue are discharged from the slag discharge end 103c of the centrifuge tube 102 into the filter residue ring groove 202 under the action of centrifugal force.

[0030] The operation process in this embodiment is as follows:

[0031] Liquid enters the centrifuge cylinder 102 from the inlet funnel 101. The centrifuge cylinder 102 rotates and throws the liquid into the centrifuge channel 102a and into the centrifuge tube 103. When the liquid rotates in the centrifuge tube 103, due to the different densities of the clear liquid and impurities, the clear liquid with lower density is discharged from the upper end of the centrifuge tube 103 and enters the clear liquid ring tank 201, while the impurities with higher density precipitate from the lower end of the centrifuge tube 103 and enter the filter residue ring tank 202. Example 2

[0032] Please see Figures 1 to 5 Based on Embodiment 1, the collecting component 2 further includes an annular upper tray 203 and a receiving component 204. The clear liquid ring groove 201 is fixedly installed on the annular upper tray 203, and a tray plate 203b is fixedly installed at the lower end of the annular upper tray 203. The receiving component 204 is installed on the upper end of the tray plate 203b, so that the weight of the centrifuge cylinder 102 is supported by the receiving component 204.

[0033] Specifically, an annular upper tray 203 is fixedly installed at the lower end of the clear liquid annular tank 201. A set of vertical connecting columns 203a are fixedly arranged in a circumferential array on the lower end plate surface of the annular upper tray 203. A support plate 203b is fixedly installed at the lower end of the set of connecting columns 203a. The filter residue annular tank 202 is fixedly installed on the upper end plate surface of the support plate 203b.

[0034] Furthermore, a vertical transmission rod 102b is fixedly provided on the lower end face of the centrifuge cylinder 102. The transmission rod 102b passes through the support plate 203b. A motor sleeve 203b-1 is installed at the lower end of the support plate 203b. A centrifugal motor 203b-2 is installed inside the motor sleeve 203b-1. The output end of the centrifugal motor 203b-2 is fixedly connected to the transmission rod 102b, and the centrifuge cylinder 102 is driven to rotate by the centrifugal motor 203b-2.

[0035] Furthermore, a receiving component 204 is installed on the pallet 203b, which is sleeved on the outside of the transmission rod 102b.

[0036] Furthermore, the receiving component 204 includes a receiving sleeve 204a, a ball bearing cover 204b, and a set of balls 204c. The receiving sleeve 204a is sleeved on the outside of the transmission rod 102b. A ball bearing seat 204a-1 is fixedly provided on the upper end of the receiving sleeve 204a. A set of hemispherical ball grooves 204a-2 are fixedly arranged in a circumferential array on the upper end plate surface of the ball bearing seat 204a-1. A set of balls 204c are rotatably installed in the ball grooves 204a-2. A set of ball bearing through holes 204b-1 are opened in a circumferential array on the cover surface of the ball bearing cover 204b. The ball bearing cover 204b is threaded on the upper end of the ball bearing seat 204a-1. A set of balls 204c pass through the ball bearing through holes 204b-1. The balls 204c roll in contact with the lower end face of the centrifuge cylinder 102, thereby reducing the friction of the centrifuge cylinder 102 when it rotates.

[0037] The operation process in this embodiment is as follows:

[0038] The centrifugal motor 203b-2 drives the centrifuge cylinder 102 to rotate, and throws the liquid in the centrifuge cylinder 102 into the centrifuge tube 103 for separation. The weight of the centrifuge cylinder 102 is supported by the receiving component 204. At the same time, when the centrifuge cylinder 102 rotates, the lower end face of the centrifuge cylinder 102 rolls against the roller 204c in the receiving component 204, thereby reducing the friction force when the centrifuge cylinder 102 rotates.
