Description

Technical Field

[0001] The invention relates to the technical field of wastewater treatment, in particular to a high-efficiency wastewater filtering and purification device. Background Art

[0002] In the process of industrial production, a lot of wastewater is often generated, which needs to be treated biochemically and meet the standards before being discharged. In the process of wastewater treatment, it is necessary to add chemicals to the wastewater to combine the settleable particles in the wastewater and separate them in the form of precipitation.

[0003] After the existing wastewater is treated with chemicals, it is discharged into a sedimentation tank for sedimentation, so that the flocculants settle under the action of gravity, and then the supernatant is discharged to separate the flocculent impurities. The traditional sedimentation process takes a long time and affects the wastewater treatment efficiency.

[0004] Therefore, the present application provides a high-efficiency wastewater filtration and purification device to improve the separation efficiency of flocculants in wastewater. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a high-efficiency wastewater filtering and purification device.

[0006] The technical solution adopted by the present invention to solve the technical problem is: a high-efficiency wastewater filtering and purification device, comprising A separation part is used to separate wastewater and flocculants, and the separation part includes a separation box, a clean water tank and a spiral separation channel. The clean water tank is located on the upper side of the separation box, and the separation channel is coaxially arranged with the separation box. A separation water cavity is formed between the outer side of the separation channel and the separation box. A separation water hole is provided between the end of the separation channel and the side opposite to the axis of the separation box and the separation water cavity, and the top of the separation water cavity is connected with the inside of the clean water tank. A collecting bucket is arranged at the lower side of the separation part, and a sewage bucket is arranged inside the collecting bucket, and the sewage bucket is used to collect the flocculants separated by the separation part; The supporting part is used to support the separating part. A connecting pipe is provided on the upper part of the supporting part. The top of the separating part is connected with a driving pipe. The upper end of the driving pipe is rotatably sealed with the bottom of the connecting pipe. The outer side of the supporting pipe is connected with a driving part, which is used to drive the separating part to rotate.

[0007] As an optimization, the separation box and the clean water tank are integrally formed, the separation box and the clean water tank are coaxially arranged, and a drainage outlet is opened on the upper side of the clean water tank.

[0008] As an optimization, the outer end of the separation channel passes through the side wall of the separation box and is arranged on the outside of the separation box. A counterweight block is provided on the side elevation of the separation box. The counterweight block and the outer end of the separation channel are symmetrically arranged in the vertical direction. A sewage pipe is provided at the bottom of the outer end of the separation channel. The bottom of the sewage pipe is connected to a first sealing plug. The top of the sewage barrel is open, and a second sealing plug is connected to the opening.

[0009] As an optimization, a water supply hole is provided between the top of the separation water chamber and the clean water tank.

[0010] As an optimization, the pitch of the separation channel gradually increases from inside to outside.

[0011] As an optimization, the driving tube is rotatably connected to the supporting part, a connecting gear is provided on the outside of the driving tube, the driving part includes a driving motor, an output shaft of the driving motor is connected to a driving gear, and the driving gear is meshingly connected to the connecting gear.

[0012] As an optimization, the support part includes a support frame arranged on the upper side of the collection barrel, the connecting pipe is fixedly connected to the support frame, and the driving pipe is rotatably connected to the support frame.

[0013] As an optimization, the opening of the collecting bucket is upward, and the diameter of the collecting bucket is larger than the diameter of the separating part.

[0014] This scheme is a high-efficiency wastewater filtration and purification device, which has the following benefits: The present application sets a spiral separation channel inside the separation box, and the width of the separation channel gradually increases. Through the rotation of the separation box, the wastewater is centrifuged, so that the flocculants are discharged outward along the outer side of the separation channel. As the diameter of the separation channel increases, the centrifugal force on the flocculants increases, so that the flocculants are discharged outward along the separation channel, thereby improving the separation effect of the flocculants. The present invention can separate wastewater and floccules at a relatively low rotation speed within a certain rotating space, thereby realizing the gradual centrifugation of floccules. The spiral separation channel actually increases the length of the liquid separation path, so that solid-liquid separation can be completed before the floccules reach the end of the separation channel. Compared with the separation method of sedimentation and standing, the separation efficiency is higher. During the separation process, the floccules move along the outer side of the separation channel, and the clean water moves along the inner side of the separation channel, which facilitates the separation of clean water and floccules. When centrifugation is performed directly without a spiral partition, the flocculants tend to stick to the inner wall of the equipment and are difficult to clean. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The wastewater with flocculant added is added into the separation box 1 from top to bottom, and the wastewater directly enters the axis of the separation channel 8. The separated floccules (sediments) gather at the outer end of the separation channel 8, and enter the clean water tank 2 when the separation water chamber 9 is full of water.

[0026] A spiral partition is arranged inside the separation box 1 , and the partition divides the separation box 1 into a separation channel 8 and a separation water chamber 9 .

[0027] like Figure 2 As shown, the separation box 1 and the clean water tank 2 are integrally formed, the separation box 1 and the clean water tank 2 are coaxially arranged, and a drain port 11 is opened on the upper side of the clean water tank 2.

[0028] like Figure 1 , 3 and Figure 5 As shown, the outer end of the separation channel 8 passes through the side wall of the separation box 1 and is arranged on the outside of the separation box 1. The side elevation of the separation box 1 is provided with a counterweight block 12, and the counterweight block 12 is symmetrically arranged with the outer end of the separation channel 8 in the vertical direction. A sewage pipe 13 is provided at the bottom of the outer end of the separation channel 8, and the bottom of the sewage pipe 13 is connected to a first sealing plug; The top of the sewage barrel 4 is open, and a second sealing plug is connected to the opening.

[0031] like Figure 6 As shown, the pitch of the separation channel 8 gradually increases from the inside to the outside.

[0032] Under the action of centrifugal force, the floccules are thrown outward from the axis of the separation channel 8. The further outward, the greater the centrifugal force, the better the separation effect.

As the width of the separation channel 8 gradually increases, the flocculants are separated spirally outward along the separation channel 8. When the floccules move along the separation channel 8 to the outside of the outer end of the separation channel 8, the separated clean water enters the separation water chamber 9 through the separation water hole 10; The clean water is further precipitated and separated in the separation water chamber 9, and the supernatant enters the clean water tank 2 through the water inlet 14, and finally is discharged into the collection bucket 3 through the drain port 11; The floccules gradually gather at the outer end of the separation channel 8 through the separation channel 8 , and finally the sewage discharge pipe 13 can be opened to discharge the floccules into the collection bucket 3 through the sewage discharge pipe 13 .
