Description

Technical Field

[0001] This utility model relates to the field of deodorization technology, specifically to an automatic sludge removal and anti-clogging biological deodorization device. Background Technology

[0002] Biological filters are widely used in sewage treatment plants, garbage transfer stations and other fields due to their advantages such as simple equipment and process, rapid deodorization and high treatment efficiency.

[0003] However, existing biological filters suffer from the following problems in practical applications: First, biofilm detachment and sludge deposition occur because the spraying action often causes biofilm to detach and deposit at the bottom of the tank, forming a large amount of bottom sludge, which affects the effective discharge of wastewater. Second, nozzle clogging and high maintenance costs occur because impurities in the circulating liquid easily clog the nozzles, affecting the spraying effect and increasing maintenance costs. Third, secondary pollution occurs because the bottom sludge accumulates in the biological filter for a long time, making it inconvenient to clean in a timely manner and easily releasing odors, which reduces the overall treatment effect of the deodorization system. In view of this, the present invention aims to solve the above problems by providing a biological deodorization device that can automatically remove sludge, effectively prevent clogging, and improve the deodorization effect. Utility Model Content

[0004] The purpose of this invention is to provide an automatic dredging, anti-clogging, and biological deodorizing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic dredging, anti-clogging, and biological deodorizing device, comprising a main body, wherein the main body includes:

[0006] The box has an air outlet pipe connected to its top, an air inlet pipe connected to its left side, a drain pipe connected to its lower right side, and a packing layer fixedly connected to the middle of the box.

[0007] A motor is installed at the lower end of the air intake pipe. One end of the motor is fixedly connected to the housing. An inspection door is installed below the motor. The inspection door is rotatably connected to the housing via a hinge.

[0008] Furthermore, a lead screw is fixedly connected to the output end of the motor, and a slider is threadedly connected to the middle of the lead screw. Protective covers are provided on the top and left and right sides of the lead screw. The protective covers are U-shaped and are fitted over the outside of the lead screw.

[0009] Furthermore, a linear slide rail is slidably connected to the upper end of the slider, and the left and right ends of the linear slide rail are fixedly connected to the inner wall of the box.

[0010] Furthermore, an upper scraper is fixedly connected to the bottom end of the slider. The upper scraper is a steel toothed brush. Connecting plates are fixedly connected to both sides of the upper scraper. A lower scraper is fixedly connected to the lower end of the connecting plates. The lower scraper is a smooth scraper.

[0011] Furthermore, a filter plate is provided between the lower scraper and the upper scraper, the filter plate is fixedly connected to the inner wall of the box, and a material discharge port is provided on the right side of the filter plate.

[0012] Furthermore, the lower scraper has a slot at its lower end, and the lower scraper is engaged with the mud storage box through the slot. Guide rollers are provided on the left and right sides of the mud storage box, and a matching guide rail is provided at the corresponding position on the inner wall of the box. The mud storage box slides with the guide rollers and the guide rail. Several small holes are provided at the bottom of the mud storage box.

[0013] Furthermore, a circulating liquid tank is provided below the filter plate, and a return pipe is connected to the right side of the circulating liquid tank. A circulating water pump is fixedly connected to the lower end of the return pipe.

[0014] Furthermore, the lower middle end of the return pipe is connected to a first spray pipe, and the right end of the first spray pipe is fixedly connected to a first electric valve.

[0015] Furthermore, the top end of the return pipe is connected to a second spray pipe, and the right end of the second spray pipe is fixedly connected to a second electric valve.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By configuring a motor, lead screw, slider, linear guide rail, upper scraper, lower scraper, and connecting plate, starting the motor drives the lead screw to rotate, causing the slider to move left and right. The slider then moves the upper and lower scrapers left and right together, facilitating the removal of sludge from the upper and lower surfaces of the filter plates. This system offers a high degree of automation, ease of operation, and low operating costs. The filter plates intercept sludge and prevent blockage of the return pipe. Furthermore, protective covers are added above and on both sides of the lead screw to effectively isolate sludge and liquid splashes, ensuring the cleanliness and accuracy of the lead screw drive. Smooth operation significantly improves the reliability and service life of the device. By setting up a sludge storage box and small holes, the sludge can be scraped into the sludge storage box when the lower scraper moves left and right. When it moves to the far right, the sludge on the upper part of the filter plate falls into the sludge storage box through the discharge port to collect the sludge on the filter plate. The bottom of the sludge storage box is equipped with multiple small holes to drain excess water and reduce the weight of the sludge storage box. When the sludge storage box is full, the sludge storage box that is locked at the lower end of the lower scraper can be removed, cleaned and installed by opening the maintenance door without affecting the normal operation of the biological deodorization system and effectively enhancing the deodorization effect.

[0018] By setting up a circulating liquid tank, circulating water pump, return pipe, first spray pipe, second spray pipe, first electric valve, second electric valve, and drain pipe, the circulating water pump is started to pump the circulating liquid into the first and second spray pipes for spraying. The first and second spray pipes are respectively equipped with a first electric valve and a second electric valve to control their spraying time. The second spray pipe is used to humidify the packing material, and the first spray pipe is used to rinse the protective cover and filter plate to remove residual sludge, preventing sludge accumulation on the protective cover and preventing secondary treatment due to incomplete cleaning by the scraper. The waste liquid after rinsing is discharged through the drain pipe located at the bottom of the tank, which saves water resources, optimizes the internal design of the biological filter, reduces waste liquid discharge and nozzle clogging pressure, and eliminates the need to stop the machine to treat sludge, effectively enhancing the practicality of the device.

The second spray pipe is used to humidify the packing material. The first spray pipe 111 is used to rinse the residual sludge on the protective cover 20 and the filter plate 102 to prevent sludge accumulation on the protective cover 20 and to prevent secondary treatment due to incomplete cleaning by the scraper. The waste liquid after rinsing is discharged through the drain pipe 107 set at the bottom of the tank 11.
