Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater treatment pool with an easy-to-maintain filter screen. Background Art

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscape, medical treatment, and catering, and is increasingly entering the daily lives of ordinary people. In actual production, volatile acidic gases often exist in wastewater.

[0003] After searching, the Chinese patent with announcement number: CN211255529U discloses a wastewater treatment pool, including a pool body, an inlet pipe, a drain pipe, a holder and a filter screen, the pool bottom of the pool body is inclined, the top of the pool body is horizontally arranged, the end of the pool body located at the higher end of the pool bottom is fixed with an inlet pipe, and the inlet pipe is located at the upper end of the pool body, the end of the pool body away from the inlet pipe is fixed with a drain pipe, and the drain pipe is located at a position of the pool body close to the bottom, the inner wall of the pool body is equidistantly fixed with holders, and the holders are symmetrically arranged on the inner wall of the pool body, and a plurality of filter screens are equidistantly arranged inside the pool body. In this wastewater treatment pool, wastewater is introduced into the pool body through the inlet pipe, and flocculant is mixed into the pool body, and then precipitation is carried out in the pool body. After precipitation, when discharging, the sediment and other particles in the wastewater will be intercepted in turn by the filter screen, and the sediments of the same particles will be intercepted between the same filter screen, which is convenient for the subsequent recycling and treatment.

[0004] The working principle of the above patent mentions that "wastewater is introduced into the pool 1 through the water inlet pipe 2, and flocculant is mixed into the pool 1, and then precipitated in the pool 1. When discharged after precipitation, the precipitate and other particles in the wastewater will be intercepted in turn by the filter 5, and the precipitate of the same particles will be intercepted between the same filter 5, which is convenient for the subsequent recycling treatment." However, in the above document, since the wastewater is only filtered through the filter, if the impurities in the wastewater are too large, it is very easy to cause the filter to be blocked, resulting in the user having to take out and clean the filter many times before the wastewater can be treated. In view of the above problems, a wastewater treatment pool with an easy-to-maintain filter is proposed to solve the above problems. Utility Model Content

[0036] Working principle: First, pull out the two filter racks 3 to clean them, then align the two filter racks 3 with the limit blocks 2 on both sides of the pool 1 to lock and fix them, then start the motor 8 to drive the coupling 9 to rotate and drive the rotor 11 and the crushing leaves 12 to rotate, then pour the wastewater into it through the water inlet pipe 13, after the wastewater enters the water inlet pipe 13, the impurities in the wastewater will be cut and crushed into fine fragments by the crushing leaves 12, and flow into the curved pipe 5 through the filter plate 10 and finally into the pool 1, and then the user can pour the flocculant into the pool 1, let the wastewater in the pool 1 settle, and then pass through the two filter racks 3 for filtering and treatment, and finally flow out from the outlet pipe 25 to complete the wastewater treatment and purification.

[0037] After the pool 1 has been used for a period of time, dirt will remain on the inner wall of the pool 1. First, an external water source is connected through the through pipe 20, and water is allowed to flow into the cleaning ball 21 through the through pipe 20 and spray out to flush the inner wall of the pool 1. Then, the motor 2 15 is started to drive the cross-threaded rod 16 to rotate, and the cross-threaded rod 16 is allowed to rotate and connect through the limit piece 19 in the through hole 18 of the slider 17 to drive the slider 17 to slide back and forth left and right, and then cooperate with the sleeve frame 2 23 connected to the slider 17 through the through hole 22 to assist the slider 17 to stabilize at the top of the pool 1 and slide left and right to carefully clean the inner wall of the pool 1.
