Description

Technical Field

[0001] This utility model relates to the field of water storage tank technology, specifically to a water treatment tank that facilitates sewage discharge. Background Technology

[0002] Water treatment tanks are the core water storage and treatment units in water treatment systems, widely used in central air conditioning cooling circulating water systems, industrial process cooling systems, domestic water supply systems, and agricultural irrigation systems. Their core function is to store water. Although most indicators of the water are improved after treatment, sediment inevitably accumulates at the bottom of the tank. This sediment becomes a breeding ground for bacteria and microorganisms, leading to water quality deterioration and increased pump load, resulting in higher energy consumption.

[0003] Currently, cleaning the sludge at the bottom of water tanks mainly relies on regular manual cleaning. This requires stopping the water tank, draining the water, and then having maintenance personnel enter the tank to manually scrub it. This is not only labor-intensive and inefficient, but also requires interrupting the water supply during cleaning, affecting the continuous and stable operation of the entire system.

[0004] Therefore, this utility model proposes a water treatment tank that facilitates sewage discharge, in order to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this utility model is to provide a water treatment tank that facilitates sewage discharge, thereby solving the problem in the prior art where the sludge at the bottom of the tank requires manual cleaning, which is labor-intensive and affects the continuous and stable operation of the entire system.

[0006] The technical solution adopted by this utility model to solve its technical problem is: A water treatment tank for easy sewage discharge includes a tank body, a filter cartridge connected inside the tank body, the filter cartridge being conical in shape, the filter cartridge being detachably connected to the lower end of the tank body via a flange, the larger diameter end of the filter cartridge being open, the open end of the filter cartridge being detachably fitted with a sealing end cap, a scraping component being coaxially arranged inside the filter cartridge, the scraping component being fitted against the inner wall of the filter cartridge, the drive shaft of a drive motor passing through the side wall of the tank body and coaxially connected to the scraping component, the drive motor being detachably connected to the tank body via a flange; The side walls of the water tank body are respectively connected to an inlet pipe and an outlet pipe. The inlet pipe is connected to the inside of the filter cartridge, and both the inlet pipe and the outlet pipe are located at the upper end of the filter cartridge. The top of the water tank body is connected to a water inlet, the lower end of the side wall of the water tank body is connected to a water outlet, the upper end of the side wall of the water tank body is connected to an overflow outlet, and a one-way valve is connected to the overflow outlet.

[0007] Furthermore, the scraping assembly includes a central shaft and multiple scraper arms. The central shaft is coaxially and detachably connected to the drive shaft of the drive motor. The scraper arms are arranged circumferentially along the central shaft, and the ends of the scraper arms are connected to scrapers via compression springs.

[0008] Furthermore, the scraper is made of polytetrafluoroethylene (PTFE), and the PTFE in contact with the inner wall of the filter cartridge is wavy.

[0009] Furthermore, a circulating filter pump is connected to the top of the water tank body. The water supply pipe of the circulating filter pump passes through the water tank body and extends to the lower end of the interior. The drain pipe of the circulating filter pump is connected to the interior of the filter cartridge.

[0010] Furthermore, a waist band is provided in the middle of the side wall of the water tank body. The waist band is arranged around the perimeter of the side wall of the water tank body. A reinforcing rib is connected between the waist band and the water tank body. A liquid level gauge is provided above the waist band and is connected to the side wall of the water tank body.

[0013] In summary, compared with the prior art, the beneficial effects of this utility model are as follows: This invention can drive the scraping component to rotate via the drive shaft of the drive motor, completely peeling off the sludge adhering to the inner wall. The peeled sludge slides down the inner wall of the conical filter cylinder under the action of gravity. The sealing end cap at the opening end of the filter cylinder can be removed, and the sludge deposited at the bottom of the filter cylinder can be discharged directly from the opening end. The cleaning process is short, and the clean water in the interlayer space of the water tank can still be supplied normally through the outlet, without affecting the continuous operation of the system.

[0014] When a comprehensive inspection or maintenance of the water tank is required, the sealed door on the inspection hole at the bottom of the side wall of the water tank body can be opened. Maintenance personnel do not need to enter the tank body and can complete the relevant operations through the inspection hole, which reduces labor intensity and improves maintenance safety.

[0015] This invention allows for quick disassembly and replacement of the filter cartridge via a flange structure, and the drive motor can be disassembled and repaired via a flange. Both the scraper arm and the central shaft are detachable, facilitating individual replacement of parts and reducing maintenance costs. Attached Figure Description

[0019] like Figure 1-5As shown, a water treatment tank for easy sewage discharge includes a tank body 1. A filter cartridge 2 is connected inside the tank body 1. The filter cartridge 2 is conical and detachably connected to the lower end of the tank body 1 via a flange. The end of the filter cartridge 2 with a larger diameter is open, and a detachable sealing end cap 3 is attached to the open end. A scraping assembly is coaxially arranged inside the filter cartridge 2, fitting snugly against the inner wall of the filter cartridge 2. The drive shaft of a drive motor 4 passes through the side wall of the tank body 1 and is coaxially connected to the scraping assembly. The drive motor 4 is detachably connected to the tank body 1 via a flange. The scraping assembly includes a central shaft 5 and multiple scraper arms 6. The central shaft 5 is coaxially and detachably connected to the drive shaft of the drive motor 4. The scraper arms 6 are arranged circumferentially along the central shaft 5, and each scraper arm 6 has a scraper 8 connected to its end via a compression spring 7. The scraper 8 is made of polytetrafluoroethylene (PTFE), and the PTFE contacting the inner wall of the filter cartridge 2 is wavy.

[0020] Furthermore, the side wall of the water tank body 1 is connected to an inlet pipe 9 and an outlet pipe 10 respectively. The inlet pipe 9 is connected to the inside of the filter cartridge 2. Both the inlet pipe 9 and the outlet pipe 10 are located at the upper end of the filter cartridge 2. The top of the water tank body 1 is connected to an inlet 11. The lower end of the side wall of the water tank body 1 is connected to an outlet 12. The upper end of the side wall of the water tank body 1 is connected to an overflow outlet 13. A one-way valve 14 is connected to the overflow outlet 13.

[0021] Furthermore, a circulating filter pump 15 is connected to the top of the water tank body 1. The water supply pipe 16 of the circulating filter pump 15 passes through the water tank body 1 and extends to the lower end of the interior. The drain pipe 17 of the circulating filter pump 15 is connected to the interior of the filter cartridge 2.

[0022] Furthermore, a waist band 18 is provided in the middle of the side wall of the water tank body 1. The waist band 18 is arranged around the perimeter of the side wall of the water tank body 1, and a reinforcing rib 19 connects the waist band 18 to the water tank body 1. A level gauge 20 is installed above the waist band 18 and is connected to the side wall of the water tank body 1. Two sets of hanging lugs 21 are symmetrically connected to the upper end of the water tank body 1. An inspection hole 22 is opened at the bottom of the side wall of the water tank body 1, and a sealing door 23 is detachably connected to the inspection hole 22 by bolts.

[0023] The working process of this utility model is as follows: First, the water to be treated is directly injected into the conical filter cartridge 2 through the inlet pipe 9 on the side wall of the water tank body 1. The inlet pipe 9 is positioned at the top of the filter cartridge 2 to ensure that the water flow can evenly cover the internal space of the filter cartridge 2. The water flowing into the filter cartridge 2 permeates downward under the action of gravity. Impurities and sludge in the water are intercepted by the inner wall of the filter cartridge 2. The filtered clean water passes through the filter cartridge 2 and enters the interlayer space between the water tank body 1 and the filter cartridge 2. Finally, it is discharged through the outlet pipe 10 at the top of the side wall of the water tank body 1 to continuously supply water to the subsequent system.

[0024] Meanwhile, the level gauge 20 on the upper side wall of the water tank body 1 monitors the water level in the tank in real time. When the water level reaches the set upper limit, the one-way valve 14 at the overflow port 13 automatically opens to discharge excess water and prevent the pressure in the tank from being too high. The water inlet 11 at the top of the water tank body 1 can be used as a backup water supply channel to replenish water when the main water supply is insufficient. The water outlet 12 connected to the lower side wall of the water tank body 1 can drain the water in the water tank body 1 and then replace the water.

[0025] At the same time, the circulating filter pump 15 at the top of the water tank body 1 starts, and its water supply pipe 16 extends through the water tank body 1 to the lower end of the interior, pumping a small amount of water deposited at the bottom of the water tank to the circulating filter pump 15. After being pressurized by the pump, the water is injected back into the filter cartridge 2 through the drain pipe 17, forming an internal circulation filter.

[0026] As the filtration process continues, the sludge trapped on the inner wall of the filter cartridge 2 gradually increases. When the set cleaning cycle is reached or the resistance of the filter cartridge 2 increases as determined by changes in the liquid level, the sludge cleaning program is initiated. This process does not require stopping the water supply, enabling continuous operation. The drive motor 4, connected to the scraping assembly, is then activated. The drive shaft of the drive motor 4 drives the central shaft 5 of the scraping assembly to rotate coaxially. Multiple scraper arms 6, arranged circumferentially around the central shaft 5, rotate synchronously with the central shaft 5. The scraper arms 6 are connected to scraper blades 8 via compression springs 7 at their ends. Under the spring force, these scraper blades remain in close contact with the inner wall of the conical filter cartridge 2, ensuring effective cleaning. The scraper blades 8 are made of polytetrafluoroethylene (PTFE), and their wavy design at the contact end with the inner wall of the filter cartridge 2 enhances the scraping effect, thoroughly removing the sludge adhering to the inner wall. The removed sludge then slides down the inner wall of the conical filter cartridge 2 under gravity, collecting in the area with the larger diameter of the filter cartridge 2.

[0027] Then, the water supply is stopped, the sealing end cap 3 at the opening end of the filter cartridge 2 is removed, and the sludge deposited at the bottom of the filter cartridge 2 can be discharged directly from the opening end. The cleaning process is short, and the clean water in the interlayer space of the water tank body 1 can still be supplied normally through the outlet 12 without affecting the continuous operation of the system.

[0028] The waist hoop 18 in the middle of the side wall of the water tank body 1 is set in the circumferential direction. The reinforcing rib 19 between the waist hoop 18 and the water tank body 1 significantly improves the structural strength of the tank and prevents the tank from deforming. The two sets of hanging ears 21 symmetrically connected at the upper end of the water tank body 1 facilitate the hoisting and installation of the water tank and improve the flexibility of equipment deployment.
