Description

Technical Field

[0001] This utility model relates to the field of wastewater pretreatment technology, specifically a water supply and drainage wastewater pretreatment device. Background Technology

[0002] A published patent document with announcement number CN 220159375 U discloses a municipal water supply and drainage wastewater pretreatment device, including a treatment tank. Support legs are fixedly connected to the four corners of the lower end of the treatment tank. A stirring mechanism is fixedly connected to the middle of the lower end of the treatment tank. A control panel is fixedly connected to the lower front end of the treatment tank. A dosing pipe is fixedly connected to the upper right end of the treatment tank. A water inlet is fixedly connected to the left end of the treatment tank. A groove is formed at the upper end of the treatment tank, and a filter mechanism is fixedly connected to the left wall of the groove. The filter mechanism is located above the stirring mechanism. By setting up the stirring mechanism and starting the motor, the motor drives the transmission rod to rotate, thereby causing the transmission rod to drive three stirring blades to stir the wastewater at the bottom of the treatment tank. This municipal water supply and drainage wastewater pretreatment device, through its filtration mechanism, can filter impurities in the wastewater.

[0003] In actual use, the above devices are prone to clogging due to their limited capacity, requiring regular cleaning. To prevent impurities from falling out of the lower filter cylinder, wastewater treatment must be stopped before cleaning can be carried out, which is not conducive to the continuity of wastewater treatment. Therefore, this application provides a pretreatment device for water supply and drainage wastewater. Utility Model Content

[0004] The purpose of this utility model is to provide a pretreatment device for water supply and drainage sewage, which solves the problems mentioned in the background art.

[0005] This application provides a wastewater pretreatment device, including a treatment tank. An inlet pipe is fixedly installed on the top of the treatment tank. A filter mechanism is fixedly installed inside the treatment tank, and the inlet pipe is connected to the filter mechanism. A collection tank is connected to one side of the filter mechanism. A shielding mechanism is provided inside the collection tank. The shielding mechanism includes a baffle plate, which is hinged to the inside of the collection tank. An L-shaped frame is fixedly installed inside the collection tank above the baffle plate. Two sets of first connecting blocks are fixedly installed on the top of the baffle plate, and two sets of second connecting blocks are fixedly installed on the bottom of the L-shaped frame. A spring is installed between the two sets of opposing first and second connecting blocks. A dosing pipe is fixedly installed on one side of the treatment tank below the inlet pipe.

[0006] By adopting the above technical solution, sewage enters the filter cartridge through the inlet pipe and is filtered through the filter holes. The sewage falls to the bottom of the treatment tank, and sewage treatment chemicals are added to the treatment tank through the dosing pipe. At the same time, impurities in the sewage remain in the filter cartridge. Since the inner ring of the filter cartridge is inclined, the impurities will slide to one side of the baffle. As the impurities accumulate, they continue to compress the baffle. When the compressive force on the baffle exceeds the elasticity of the two sets of springs, the impurities fall into the inside of the collection tank. The baffle automatically resets under the elastic action of the two sets of springs. By collecting the impurities in the collection tank, the possibility of filter cartridge blockage is reduced. At the same time, operators can periodically clean the accumulated impurities in the collection tank without stopping the entire sewage treatment process, which greatly improves the continuity and efficiency of sewage treatment.

[0007] Optionally, a motor is fixedly installed at the bottom of the processing box, a stirring shaft is fixedly installed at the output end of the motor, and stirring blades are fixedly installed at the bottom of the processing box through the top of the stirring shaft.

[0008] By adopting the above technical solution, the mixing of sewage and chemical agents is accelerated by driving the stirring shaft and stirring blades with a motor, thereby improving the uniformity and efficiency of sewage treatment.

[0009] Optionally, the top of the processing box is hinged to a box cover above the baffle, and a handle is fixedly installed on the top of the box cover.

[0010] By adopting the above technical solution, the baffle is covered by a box lid, and the box lid is easy to open and close with a handle, so as to clean the impurities collected inside the baffle.

[0011] Optionally, an outer sleeve is fixedly installed on one side of the second connecting block, and an inner sleeve is slidably connected inside the outer sleeve. The side of the inner sleeve away from the outer sleeve is fixedly installed on one side of the first connecting block, and the outer sleeve and the inner sleeve are located on the outer ring of the spring.

[0012] By adopting the above technical solution, the spring is waterproofed by the outer sleeve and the inner sleeve. At the same time, when the spring extends or retracts, the inner sleeve slides inside the outer sleeve, which helps to extend the service life of the spring.

[0013] Optionally, the spring is provided with a telescopic guide rod inside, one end of which is installed on one side of the second connecting block, and the telescopic end of which is installed on one side of the first connecting block.

[0014] By adopting the above technical solution, the telescopic guide rod guides the spring during its extension and retraction, which is beneficial to the stability and reliability of the spring during elastic extension and retraction, and helps to extend the service life of the spring.

[0015] Optionally, a drain pipe is fixedly installed at the bottom of the processing box, and an electrically controlled valve is installed inside the drain pipe.

[0016] By adopting the above technical solution, the treated wastewater in the treatment tank is discharged through a drain pipe, and the water flow rate at the drain pipe is controlled by an electric control valve, which improves the practicality of use.

[0017] Optionally, a controller is provided on one side of the treatment box, and the controller is located above the drain pipe.

[0018] By adopting the above technical solution, the controller facilitates the operation of this device by the staff.

[0019] Optionally, the bottom of the baffle is provided with several sets of drainage holes.

[0020] By adopting the above technical solution, the moisture contained in the impurities in the collection tank is allowed to fall into the treatment tank through the drain hole, which improves the practicality of use.

[0021] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0022] 1. Wastewater enters the filter cartridge through the inlet pipe and is filtered through the filter holes. The wastewater falls to the bottom of the treatment tank. Wastewater treatment chemicals are added to the treatment tank through the dosing pipe. At the same time, impurities in the wastewater remain in the filter cartridge. Because the inner ring of the filter cartridge is inclined, the impurities will slide to one side of the baffle. As the impurities accumulate, they continue to compress the baffle. When the compressive force on the baffle exceeds the elasticity of the two sets of springs, the impurities fall into the inside of the collection tank. The baffle automatically resets under the elasticity of the two sets of springs. By collecting the impurities in the collection tank, the possibility of filter cartridge blockage is reduced. At the same time, operators can periodically clean the accumulated impurities in the collection tank without stopping the entire wastewater treatment process, which greatly improves the continuity and efficiency of wastewater treatment.

[0023] 2. The motor drives the stirring shaft and stirring blades to rotate, which accelerates the mixing of sewage and chemical agents, improving the uniformity and efficiency of sewage treatment. Attached Figure Description

One end of the telescopic guide rod 14 is installed on one side of the second connecting block 504, and the telescopic end of the telescopic guide rod 14 is installed on one side of the first connecting block 503.

[0046] Working principle: Wastewater enters the filter cylinder 301 through the inlet pipe 2 and is filtered through the filter holes 302. The wastewater falls to the bottom of the treatment tank 1. Wastewater treatment chemicals are added to the treatment tank 1 through the dosing pipe 6. At the same time, impurities in the wastewater remain inside the filter cylinder 301. Because the inner ring of the filter cylinder 301 is inclined, the impurities slide onto one side of the baffle 501. As the impurities accumulate, they continue to compress the baffle 501. When the compressive force on the baffle 501 exceeds the elasticity of the two sets of springs 505, the impurities fall into the inside of the collection tank 4. The baffle 501 automatically resets under the elastic action of the two sets of springs 505. The motor 7 drives the stirring shaft 8 and stirring blades 9 to rotate, accelerating the mixing of wastewater and chemicals. The mixture is then discharged through the tank cover. 10 covers the baffle 501, and the handle 11 facilitates opening and closing of the box cover 10.

The telescopic guide rod 14 guides the extension and retraction of the spring 505, which helps to extend the service life of the spring 505. The treated wastewater in the treatment box 1 is discharged through the drain pipe 15. The water flow rate discharged from the drain pipe 15 is controlled by the electric control valve 16. The controller 17 facilitates operation of the device by the staff. The water contained in the impurities in the collection box 4 falls into the interior of the treatment box 1 through the drain hole 18.
