Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment grit filtration and purification tank. Background Technology

[0002] Sewage can mix with silt during migration, flow or collection. If the sand in the sewage is not removed by pre-sedimentation and separation, it will affect the operation of subsequent treatment equipment. Therefore, sewage needs to be filtered by sedimentation. Sewage treatment sedimentation and filtration purification tank is an important facility in sewage treatment technology. Its main purpose is to treat sand particles in sewage to facilitate the subsequent sewage treatment process.

[0003] There are various methods for wastewater treatment grit filtration and purification, among which aerated grit chambers are more commonly used due to their higher efficiency in wastewater treatment. However, in commonly used aerated grit chambers, waste of sludge and sand during wastewater treatment and difficulties in maintenance can lead to air leakage due to detachment of aeration pipes. Chinese Patent Publication No. CN221191703U discloses a wastewater treatment grit filtration and purification tank. By setting up a lifting component, the height of the aeration pipe can be adjusted according to specific usage conditions, thereby saving aeration usage. The lifting structure also makes maintenance of the aeration pipe convenient. However, in actual operation, the lifting structure cannot disassemble the aeration pipe, and when the aeration pipe is damaged, replacement is extremely inconvenient. Therefore, we propose a wastewater treatment grit filtration and purification tank. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a wastewater treatment grit filtration and purification tank. By setting the assembly block as a U-shaped structure and having a locking block movably installed inside by a snap ring, the air supply pipe and aeration pipe are equipped with limiting components after installation and are also easy to disassemble. This solves the problem of the aeration pipe being difficult to disassemble and maintain. At the same time, by movably installing the assembly block on the top of the purification tank body, the air supply pipe, aeration pipe and assembly block can be assembled separately, further increasing the convenience of aeration pipe installation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A wastewater treatment grit filtration and purification tank includes a main body, an assembly mechanism installed in the middle of the upper part of the main body, and an air distribution mechanism installed in the middle of the upper end of the assembly mechanism.

[0007] The assembly mechanism includes an assembly block, a lifting block fixedly installed at the outer end of the assembly block, a slot formed in the middle of the inner side of the assembly block, a groove formed inside the inner end of the assembly block, a retaining spring fixedly installed inside the groove, a retaining block fixedly installed at the outer end of the retaining spring, and the rear end of the retaining block being movably installed inside the groove via the retaining spring, so that the retaining block can be used to move inside the assembly block, thereby securing the components installed inside the assembly block and increasing the stability of the assembly block after it is connected to other components.

[0008] Furthermore, the main structure includes a purification tank body, with a water inlet at the top front end and a sand outlet at the bottom right end. A sand outlet pipe is fixedly connected to the outer end of the sand outlet. A sand baffle is fixedly installed inside the bottom of the purification tank body. Mounting blocks are fixedly installed in the middle of the left and right ends of the purification tank body. An electric push rod is fixedly installed inside the upper part of the mounting block. A crossbar is fixedly installed at the upper end of the electric push rod, and a hook is fixedly installed on the side of the lower end of the crossbar. A discharge hole is opened in the middle of the right end of the purification tank body. By setting the electric push rod, the gas distribution mechanism installed at the upper end of the purification tank body has an adjustable component, thereby increasing the ease of use of the device.

[0009] Furthermore, the gas distribution mechanism includes an air supply pipe, with a connecting pipe fixedly connected to the front end of the air supply pipe, an aeration pipe fixedly connected to the inner end of the air supply pipe, and an aeration nozzle fixedly installed in the middle of the aeration pipe. The aeration pipe is installed in a figure-7 shape at the inner end of the air supply pipe, extending downwards into the interior of the purification tank body, so that aeration can be repeatedly introduced into the interior of the purification tank body, thereby greatly improving the efficiency of the purification tank body in treating sediment in sewage.

[0010] Furthermore, the assembly block is movably installed below the crossbar via a lifting block. There are two assembly blocks, and each assembly block has a U-shaped structure. The U-shaped assembly block inserts the air supply pipe into itself, preventing the air supply pipe from being exposed. At the same time, it also provides an external mounting component for the air supply pipe, making it easy to connect the air supply pipe to the crossbar at the upper end of the electric push rod. This allows the aeration pipe to move up and down when the crossbar moves up and down.

[0011] Furthermore, the slots are evenly distributed in the middle of the inner side of the assembly block, the grooves are symmetrically distributed at the inner end of the assembly block, and the locking blocks are movably installed inside the grooves by means of snap rings.

[0012] Furthermore, the number of sand outlets corresponds to the number of sand baffles, and the mounting blocks are symmetrically distributed at both ends of the purification tank body.

[0013] Furthermore, the electric push rods are equidistantly distributed at the upper end of the mounting block, and the hooks are symmetrically distributed on the left and right sides of the lower end of the crossbar, with the hooks and the lifting blocks being compatible.

[0014] Furthermore, the air supply pipe has a square structure and is movably installed inside the assembly block above it. The aeration pipes are equidistantly distributed at the inner end of the air supply pipe, the aeration pipes are adapted to the slots, and the aeration nozzles are equidistantly distributed in the middle of the aeration pipes.

[0015] In summary, this utility model has the following beneficial effects:

[0016] 1. By setting the assembly block as a U-shaped structure and having a retaining block installed inside by means of a retaining spring, the air supply pipe and aeration pipe are equipped with a limiting component after installation and are easy to disassemble. This solves the problem of the aeration pipe being difficult to disassemble and maintain. At the same time, by movably installing the assembly block on the top of the purification tank body, the air supply pipe, aeration pipe and assembly block can be assembled separately, further increasing the convenience of aeration pipe installation.

[0017] 2. By setting an electric push rod, the air distribution mechanism installed at the upper end of the purification tank body has an adjustable component, thereby increasing the convenience of using the device. The aeration pipe and the slot are compatible and correspond to each other during installation, making the aeration pipe stable after installation. Attached Figure Description

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] Reference Figure 1-5 As shown, a wastewater treatment grit filtration and purification tank is provided in a preferred embodiment of the present invention, including a main body 1, an assembly mechanism 2 installed in the middle of the upper part of the main body 1, and an air distribution mechanism 3 installed in the middle of the upper end of the assembly mechanism 2.

[0027] The assembly mechanism 2 includes an assembly block 201. A lifting block 202 is fixedly installed on the outer end of the assembly block 201. A slot 203 is formed in the middle of the inner side of the assembly block 201. A groove 204 is formed inside the inner end of the assembly block 201. A retaining spring 205 is fixedly installed inside the groove 204. A retaining block 206 is fixedly installed on the outer end of the retaining spring 205. The rear end of the retaining block 206 is movably installed inside the groove 204 through the retaining spring 205, so that the retaining block 206 can be used to move inside the assembly block 201. This is used to lock the components installed inside the assembly block 201, thereby increasing the stability of the assembly block 201 after it is connected with other components.

[0028] The main structure 1 includes a purification tank body 101. A water inlet 102 is provided at the upper front end of the purification tank body 101. A sand outlet 103 is provided at the lower right end of the purification tank body 101. A sand outlet pipe 104 is fixedly connected to the outer end of the sand outlet 103. A sand baffle 105 is fixedly installed at the lower inside of the purification tank body 101. An installation block 106 is fixedly installed at the middle of the left and right ends of the purification tank body 101. An electric push rod 107 is fixedly installed inside the upper part of the installation block 106. A crossbar 108 is fixedly installed at the upper end of the electric push rod 107. A hook 109 is fixedly installed on the side of the lower end of the crossbar 108. A discharge hole 110 is provided at the middle of the right end of the purification tank body 101. By setting the electric push rod 107, the gas distribution mechanism 3 installed at the upper end of the purification tank body 101 has an adjustable component, thereby increasing the convenience of using the device.

[0029] The air distribution mechanism 3 includes an air supply pipe 301, a connecting pipe 302 fixedly connected to the front end of the air supply pipe 301, an aeration pipe 303 fixedly connected to the inner end of the air supply pipe 301, an aeration nozzle 304 fixedly installed in the middle of the aeration pipe 303, and the aeration pipe 303 is installed in a "7" shape at the inner end of the air supply pipe 301, extending below into the interior of the purification tank body 101, so that aeration can be repeatedly introduced into the interior of the purification tank body 101, thereby greatly improving the efficiency of the purification tank body 101 in treating sediment in sewage.

[0030] Assembly block 201 is movably installed below crossbar 108 via lifting block 202. There are two assembly blocks 201. Assembly block 201 has a U-shaped structure. The U-shaped assembly block 201 inserts the air supply pipe 301 into the interior to prevent the air supply pipe 301 from being exposed. At the same time, it also provides an external mounting component for the air supply pipe 301, which facilitates the connection between the air supply pipe 301 and the crossbar 108 at the upper end of the electric push rod 107. This allows the aeration pipe 303 to move up and down when the crossbar 108 moves up and down.

[0031] The slots 203 are evenly distributed in the middle of the inner side of the assembly block 201, and the grooves 204 are symmetrically distributed in the inner end of the assembly block 201. The locking block 206 is movably installed inside the groove 204 by the retaining spring 205. After the slots 203 connect the air supply pipe 301 and the assembly block 201, the aeration pipe 303 can be placed in a limited position. When the air supply pipe 301 is placed, the locking block 206 is manually pressed, so that it is compressed into the groove 204 by the compressibility of the retaining spring 205. After the air supply pipe 301 is placed, the locking block 206 is popped out by the rapid rebound of the retaining spring 205 and locked at the upper end of the air supply pipe 301. This increases the stability of the connection between the air supply pipe 301 and the assembly block 201. The design of this structure makes it easy to disassemble and assemble the air supply pipe 301 and the assembly block 201, thereby improving the convenience of inspection and maintenance of the air supply pipe 301.

[0032] The number of sand outlets 103 corresponds to the number of sand baffles 105. The mounting blocks 106 are symmetrically distributed on the left and right ends of the purification tank body 101. The number of sand outlets 103 and sand baffles 105 are set to correspond so that after the device treats the sedimentation of sand in the sewage, each sand baffle 105 is matched with a sand outlet 103 to achieve rapid sand discharge after sedimentation treatment.

[0033] Electric push rods 107 are evenly distributed at the upper end of mounting block 106, and hooks 109 are symmetrically distributed on the left and right sides of the lower end of crossbar 108. Hooks 109 and lifting blocks 202 are compatible. The arrangement of hooks 109 and lifting blocks 202 makes assembly block 201 and purification tank body 101 detachable, which makes it easier to assemble air supply pipe 301 and aeration pipe 303.

[0034] The air supply pipe 301 has a square structure and is movably installed inside the assembly block 201. The aeration pipes 303 are evenly distributed at the inner end of the air supply pipe 301 and are compatible with the slots 203. The aeration nozzles 304 are evenly distributed in the middle of the aeration pipes 303. The evenly distributed aeration nozzles 304 ensure that aeration is output at all levels during sewage treatment, resulting in higher efficiency and better quality of sewage sedimentation treatment.

[0035] Specific implementation process: During operation, first place the air supply pipe 301 inside the upper end of the assembly block 201. During placement, the "7"-shaped aeration pipe 303 installed at the inner end of the air supply pipe 301 corresponds to the slot 203, thus ensuring that both the air supply pipe 301 and the aeration pipe 303 have protective components on their outer sides after installation. When placing the air supply pipe 301, manually press the locking block 206, causing it to retract into the groove 204 through the compressibility of the retaining spring 205. After the air supply pipe 301 is in place, the retaining spring 205... The rapid rebound causes the locking block 206 to pop out and lock onto the upper end of the gas supply pipe 301, thereby increasing the stability of the connection between the gas supply pipe 301 and the assembly block 201. This structure makes it easy to assemble and disassemble the gas supply pipe 301 and the assembly block 201, thereby improving the convenience of maintenance of the gas supply pipe 301. The various components of this device complement each other. At the same time, the hook 109 and the lifting block 202 make the assembly block 201 and the purification tank body 101 detachable, thereby making it easier to assemble the gas supply pipe 301 and the aeration pipe 303.
