Description

TECHNICAL FIELD

[0001] The utility model relates to two sedimentation tank technical field, concretely is two sedimentation tank not production dredging equipment. BACKGROUND

[0002] Two sedimentation tanks are important components of activated sludge solid-liquid separation systems, and their main functions are to separate sludge, clarify mixed liquor, concentrate and discharge activated sludge. The working effect can directly affect the effluent quality of the wastewater treatment system and sludge separation and transportation.

[0003] Although two sedimentation tanks are convenient for separating sludge, they still have deficiencies in actual use. Excessive sludge deposition causes the effluent SS to exceed the standard. The two sedimentation tank non-production dredging equipment is put into use to solve the problem of sludge dredging at the bottom of the tank without stopping production, thereby quickly solving the problem of water quality exceeding the standard.

[0004] Therefore, the two sedimentation tank non-production dredging equipment is designed to enable it to be free from production operation constraints, clean the sludge at the bottom of the tank, ensure that the water quality meets the standard, save operation costs, reduce economic losses caused by production stoppage, and ensure the treatment capacity target task measures. UTILITY MODEL CONTENTS

[0005] In view of the deficiencies of the prior art, the utility model provides a two sedimentation tank non-production dredging equipment to solve the problem that the two sedimentation tank lacks non-production dredging equipment, which prevents the equipment from dredging sludge at the bottom of the tank without stopping production, thereby quickly solving the problem of water quality exceeding the standard.

[0006] To achieve the above purpose, the utility model is implemented by the following technical scheme: a two sedimentation tank non-production dredging equipment, including a two sedimentation tank body and a corridor, the corridor is fixedly connected to the top of the two sedimentation tank body, a mud scraper is installed at the bottom of the corridor, a mud collecting bin is installed at the bottom of the mud scraper, a mud collecting port is communicated at the front side of the mud collecting bin, an installation cylinder is fixedly connected to the front side of the mud scraper through a support, and one end of the installation cylinder extends into the inside of the mud collecting port, a sludge lifting pump is installed in the inside of the installation cylinder, and an external discharge pipe is communicated with the outlet end of the sludge lifting pump.

[0007] ADVANTAGEOUS EFFECTS

[0008] The utility model provides a two -sinker pool does not stop production and dredges equipment. Compared with prior art has the following beneficial effects: the utility model discloses the installation cylinder is set up on the mud scraper, and the installation cylinder is penetrated in the inside of the mud collection mouth, and the sludge lifting pump and the external discharge pipe are set up in the inside of the installation cylinder, so that the device can also carry out real -time sludge external discharge through the cooperation when carrying out daily mud scraping and water treatment, avoid the problem that water quality is led to water treatment easy to exceed the standard because of sludge accumulation, and the water quality reaches the standard on the basis of ensuring that the sludge is not removed in the stop production, can also reduce the economic loss caused by the stop production dredging, saves the dredging expense investment, and does not need the complex stop production approval procedure.
