Description

Technical Field

[0001] The utility model relates to the technical field of wastewater treatment, in particular to a wastewater temporary storage tank of a wastewater pretreatment system. Background Art

[0002] The wastewater pretreatment system is an important part of the sewage treatment process. Its main purpose is to preliminarily treat suspended solids, pollutants, harmful substances, etc. in the raw wastewater so that subsequent treatment units can operate more efficiently.

[0003] Wastewater holding tanks play an important role in wastewater treatment systems. The amount of wastewater generated may vary over time. Temporary holding tanks can balance this fluctuation and ensure the stable operation of the wastewater treatment system. When the wastewater treatment facility fails or undergoes maintenance, temporary holding tanks can temporarily store wastewater to prevent it from being directly discharged into the environment. The wastewater stays in the temporary holding tank for a period of time, allowing suspended matter and particulate matter to naturally settle, facilitating subsequent treatment. During the wastewater treatment process, temporary holding tanks can serve as a buffer zone to reduce the impact on the treatment system and improve the system's ability to withstand shocks.

[0004] During the use of the wastewater storage tank, the generation of sediment will cause impurities to adhere to the inner wall of the tank and be difficult to clean. These substances will damage and corrode the tank.

[0005] In addition, during the process of storing wastewater, the air pressure inside the tank will increase due to factors such as microbial fermentation in the wastewater. The current wastewater storage tanks are either opened and directly exposed to the outside world, causing foul-smelling gases to pollute the environment, or are in a closed state and do not have an effective exhaust structure, causing the wastewater storage tanks to expand and deform due to the action of air pressure, posing certain safety hazards.

[0006] To this end, we propose a wastewater storage tank for a wastewater pretreatment system to solve the existing problems. Utility Model Content

[0007] The purpose of the utility model is to address the problems existing in the background technology and to provide a wastewater temporary storage tank for a wastewater pretreatment system.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wastewater temporary storage tank of a wastewater pretreatment system, comprising a tank body, a shell, a scraper and a carbon cartridge, a front plate being provided at one end of the tank body, a rear plate being provided at the other end of the tank body, a scraper being provided on the rear plate for rotation, the scraper being closely attached to the inner wall of the tank body, an air port being provided on one side of the top end of the tank body, and an exhaust assembly being provided on the air port.

[0009] Preferably, an inlet is provided at the middle position of the top of the tank body, an outlet is provided on the front plate, and a sewage outlet is provided on the rear plate. The sewage outlet, the inlet and the outlet are all threadedly provided with screw caps.

[0010] Preferably, a motor is mounted on the outer wall of the rear plate via bolts, the shaft end of the scraper is rotatably mounted on the rear plate, and the shaft end of the scraper is connected to the output end of the motor.

[0011] Preferably, the exhaust assembly is composed of a shell, a screw, an upper block, a sealing block, a sliding column and a spring. The shell is arranged on the air port of the tank body, the sliding column is slidingly arranged inside the shell, the sealing block is arranged at the bottom end of the sliding column, and a connecting hole is provided in the inner middle section of the shell, and the sealing block is against the open top of the connecting hole.

[0012] Preferably, the screw thread is arranged at the top of the shell, the upper block is rotatably arranged at the top of the screw, the bottom end of the spring is arranged at the top of the sliding column, and the top end of the spring is arranged on the lower surface of the upper block.

[0013] Preferably, a screw hole adapted to the screw rod is provided at the top end of the shell, and the screw rod and the screw hole are engaged with each other.

[0014] Preferably, an exhaust hole is provided on the shell, the bottom end of the carbon cylinder is threadedly arranged in the exhaust hole, and the carbon cylinder is filled with an activated carbon layer.

[0015] Preferably, two supports are provided at the bottom end of the tank body, and the two supports are symmetrically distributed relative to the bottom end of the tank body.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] During use, the wastewater temporary storage tank of the wastewater pretreatment system of the utility model can introduce the wastewater in the wastewater pretreatment system into the interior of the tank body through the inlet for temporary storage. When the inner wall of the tank body needs to be cleaned, an external power supply can be connected to operate the motor, and the motor drives the scraper to rotate, and the scraper scrapes impurities along the inner wall of the tank body. Regular cleaning and maintenance can slow down the corrosion rate of the tank body, extend the service life of the temporary storage tank, and at the same time reduce the generation of stench and other unpleasant odors, thereby improving the environmental quality of the workplace.

[0018] Furthermore, the wastewater reaction inside the tank generates gas. When the internal air pressure of the tank is higher than the set standard, the gas inside the tank presses against the sealing block and moves upward, and the sealing block drives the sliding column upward, thereby causing the sliding column to compress the spring and deform. When the sealing block is away from the inner wall of the shell, the internal gas of the tank enters the shell and is discharged into the carbon cylinder through the exhaust hole of the shell. The gas is adsorbed by the activated carbon inside the carbon cylinder and purified before being discharged into the external environment. When the internal air pressure of the tank is lower than the set standard, the sealing block moves downward under the elastic force of the spring and re-blocks the connecting hole between the shell and the tank. Automatic adjustment reduces the need for manual monitoring and intervention, reduces the complexity and labor intensity of operation, and prevents the tank from deforming due to excessive internal air pressure.

[0019] Furthermore, the air pressure setting standard can be changed according to the amount of wastewater inside the tank and the degree of reaction. The person rotates the screw, and the meshing action between the screw and the shell causes the upper block to move up and down. When the upper block moves downward, the pressure exerted by the spring on the sealing block increases, thereby increasing the set standard air pressure, and vice versa, reducing the set standard air pressure, thereby making the exhaust standard adjustable, and realizing precise adjustment of the air pressure in the tank to meet different exhaust standards.

The rear plate 4 is rotatably provided with a scraper 11, and the scraper 11 is closely attached to the inner wall of the tank body 1. An air port is provided on one side of the top end of the tank body 1, and an exhaust assembly is provided on the air port.

[0030] Based on Example 1:

[0031] During use, the wastewater temporary storage tank of the wastewater pretreatment system of the present invention can introduce the wastewater in the wastewater pretreatment system into the interior of the tank body 1 through the inlet 8 for temporary storage. When the inner wall of the tank body 1 needs to be cleaned, the scraper 11 rotates and scrapes impurities along the inner wall of the tank body 1.

[0032] Furthermore, the wastewater inside the tank body 1 reacts to produce gas. When the internal pressure of the tank body 1 is higher than the set standard, the gas inside the tank body 1 presses against the sealing block 15 away from the inner wall of the shell 7, and the gas is discharged into the carbon cartridge 12. The gas is adsorbed by the activated carbon inside the carbon cartridge 12 and purified before being discharged into the external environment. When the internal pressure of the tank body 1 is lower than the set standard, the sealing block 15 moves downward under the elastic force of the spring 17 to re-block the connecting hole between the shell 7 and the tank body 1.

[0033] Furthermore, the air pressure setting standard can be changed according to the amount of wastewater inside the tank body 1 and the degree of reaction. The person rotates the screw 13, and the meshing action between the screw 13 and the shell 7 causes the upper block 14 to move up and down, thereby making the exhaust standard adjustable. The air pressure in the tank can be accurately adjusted to meet different exhaust standards.

[0034] Example 2

[0035] like Figure 1-Figure 5As shown, the utility model proposes a wastewater temporary storage tank for a wastewater pretreatment system. Compared with the first embodiment, this embodiment also includes: an inlet 8 is provided at the middle position of the top of the tank body 1, an outlet 9 is provided on the front plate 3, and a sewage outlet 5 is provided on the rear plate 4.

The shaft end of the scraper 11 is connected to the output end of the motor 6. An external power supply can be connected to make the motor 6 work, and the motor 6 drives the scraper 11 to rotate.

[0037] The exhaust assembly consists of a shell 7, a screw 13, an upper block 14, a sealing block 15, a sliding column 16 and a spring 17. The shell 7 is arranged on the gas port of the tank body 1, the sliding column 16 is slidably arranged inside the shell 7, the sealing block 15 is arranged at the bottom end of the sliding column 16, the inner middle section of the shell 7 is provided with a connecting hole, the sealing block 15 is against the top end of the opening of the connecting hole, the shell 7 is provided with an exhaust hole, the bottom end of the carbon cartridge 12 is threaded in the exhaust hole, the carbon cartridge 12 is filled with an activated carbon layer, the wastewater inside the tank body 1 reacts to produce gas, and when the internal air pressure of the tank body 1 is higher than the set standard, The gas inside the tank body 1 moves upward against the sealing block 15, and the sealing block 15 drives the sliding column 16 upward, so that the sliding column 16 compresses the spring 17 to deform. When the sealing block 15 is away from the inner wall of the shell 7, the gas inside the tank body 1 enters the shell 7 and is discharged into the carbon cylinder 12 through the exhaust hole of the shell 7. The gas is adsorbed by the activated carbon inside the carbon cylinder 12 and purified and then discharged into the external environment. When the air pressure inside the tank body 1 is lower than the set standard, the sealing block 15 moves downward under the elastic force of the spring 17 and re-blocks the connecting hole between the shell 7 and the tank body 1.

[0038] The screw 13 is threaded on the top of the shell 7, the upper block 14 is rotatably arranged on the top of the screw 13, the bottom end of the spring 17 is arranged on the top of the sliding column 16, and the top end of the spring 17 is arranged on the lower surface of the upper block 14.

The screw 13 and the screw hole are engaged with each other, and the set standard of the air pressure can be changed according to the amount of wastewater inside the tank body 1 and the degree of reaction. The person rotates the screw 13, and the meshing action between the screw 13 and the shell 7 causes the upper block 14 to perform a lifting action. When the upper block 14 descends, the pressure applied by the spring 17 to the sealing block 15 becomes greater, thereby increasing the set standard air pressure, and vice versa.

[0039] Two supports 2 are provided at the bottom end of the tank body 1 , and the two supports 2 are symmetrically distributed relative to the bottom end of the tank body 1 .
