Description

TECHNICAL FIELD

[0001] The present application relates to the field of sewage treatment, in particular to a combined sewage treatment biochemical tank convenient to clean. BACKGROUND

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse, and the purification methods mainly include physical treatment method, chemical treatment method and biological treatment method.

[0003] The sewage biochemical treatment tank in the related art usually includes an anaerobic tank and an aerobic tank arranged separately, and the anaerobic tank and the aerobic tank are communicated through a water diversion pump.

[0004] When the anaerobic tank and the aerobic tank are used for a long time, a large amount of dirt will adhere to the side wall and the bottom wall, and therefore they need to be cleaned regularly. Since the anaerobic tank and the aerobic tank are completely independent and separate, both of them need to be cleaned separately, which results in a long time consumption and low cleaning efficiency, and there is an obvious deficiency. CONTENT OF THE INVENTION

[0005] In order to improve the cleaning efficiency, the present application provides a combined sewage treatment biochemical tank convenient to clean.

[0006] The present application provides a combined sewage treatment biochemical tank convenient to clean, which adopts the following technical scheme:

[0007] The combined sewage treatment biochemical tank convenient to clean comprises a tank body with an open top, a sewage discharge pipe communicated with the tank body, a sewage discharge valve arranged on the sewage discharge pipe, a partition plate placed in the tank body to separate an inner cavity of the tank body into an anaerobic cavity and an aerobic cavity, a water diversion pump arranged outside the tank body and used to communicate the anaerobic cavity and the aerobic cavity, an expansion slot vertically formed in an inner side wall of the tank body, the partition plate extending into the expansion slot and being tightly attached to the expansion slot, a plurality of support rods hingedly connected to one side of the partition plate in the expansion slot, the support rods slidingly penetrating out of the tank body, a compensation slot vertically formed in the other side of the inner side wall of the tank body relative to the expansion slot, and a compensation plug vertically inserted into the compensation slot and in plug-fit cooperation with the partition plate.

[0008] By adopting the above technical scheme, when cleaning, the worker first pulls out the compensation plug from the compensation slot, then completely pulls out the partition plate from the expansion slot, and then rotates the partition plate to make the anaerobic cavity and the aerobic cavity form a whole, so that the worker can quickly clean the whole inner cavity of the tank body, which is convenient to operate and improves the cleaning efficiency.

[0009] Optionally, first sealing strips are arranged between the plug-fit cooperation position of the compensation plug and the partition plate and between the side wall of the expansion slot and the partition plate.

[0010] The first sealing strip improves the sealing performance between the compensation plug-in plate and the plug-in fitting part of the partition plate and between the partition plate and the sidewall of the telescopic groove, and reduces the possibility of cross-contamination of the anaerobic cavity and the aerobic cavity.

[0011] Optionally, the compensation plug-in plate and the partition plate are both arranged with a second sealing strip for being closely attached to the inner bottom wall of the pool body.

[0012] The second sealing strip improves the sealing performance between the compensation plug-in plate and the partition plate and the inner bottom wall of the pool body, and reduces the possibility of cross-contamination of the anaerobic cavity and the aerobic cavity.

[0013] Optionally, the partition plate is vertically provided with a lifting groove on one side of the support rod, a plurality of lifting blocks are slidably arranged in the lifting groove, the cross sections of the lifting groove and the lifting blocks are both dovetail-shaped, each lifting block corresponds to a support rod and is hingedly connected to the support rod, a gap is formed in the partition plate near the position of the support rod, a guide rod is vertically slidably arranged on the partition plate, a steel ball roller is arranged at the bottom end of the guide rod and abuts against the bottom wall of the pool body, a compression spring is sleeved on the guide rod and abuts against the top wall of the gap and the steel ball roller, and a cover is detachably connected to the top of the pool body and used for pressing the compensation plug-in plate and the partition plate.

[0014] During use, the cover is pressed against the compensation plug-in plate and the partition plate, and the second sealing strip abuts against the inner bottom wall of the pool body, thereby further reducing the possibility of cross-contamination of the anaerobic cavity and the aerobic cavity. During cleaning, the cover is removed, the compression spring pushes the partition plate to move upward by a certain height, and a gap is formed between the partition plate and the inner bottom wall of the pool body, thereby facilitating the flushing of dirt during cleaning.

[0015] Optionally, polytetrafluoroethylene is coated on the lifting blocks and the lifting groove.

[0016] The friction coefficient of polytetrafluoroethylene is small, and the sliding smoothness of the lifting blocks in the lifting groove is improved.

[0017] Optionally, a handle is arranged on the sidewall of the partition plate relative to the anaerobic cavity and the aerobic cavity.

[0018] The handle is arranged to facilitate the manual pulling or pushing of the partition plate out of or into the telescopic groove by workers.

[0019] Optionally, a hook is hingedly arranged on the sidewall of the pool body relative to the anaerobic cavity and the aerobic cavity and used for being hung on the handle.

[0020] The hook is hung on the handle, thereby reducing the possibility of random rotation of the partition plate during cleaning.

[0021] Optionally, a reinforcing frame is arranged in the telescopic slot, and each support rod slides through the reinforcing frame.

[0022] By using the above technical scheme, the reinforcing frame plays an auxiliary supporting role on each support rod, thereby improving the load bearing effect of the support rod on the partition plate.

[0023] To sum up, the present application has at least one of the following beneficial technical effects:

[0024] 1. During cleaning, the worker first pulls out the compensation plug from the compensation slot, then pulls out the partition plate from the telescopic slot, and then rotates the partition plate to form an integral body of the anaerobic cavity and the aerobic cavity, so that the worker can quickly clean the entire inner cavity of the pool body, which is convenient to operate and improves the cleaning efficiency.

[0025] 2. During use, the cover is pressed against the compensation plug and the partition plate, so that the second sealing strip abuts against the inner bottom wall of the pool body, further reducing the possibility of cross-contamination between the anaerobic cavity and the aerobic cavity. During cleaning, the worker removes the cover, and the compression spring drives the partition plate to move upward by a certain height, so that a gap is formed between the partition plate and the inner bottom wall of the pool body, facilitating the flushing of dirt during cleaning.
