Description

Technical Field

[0001] This utility model belongs to the technical field of siphon pipe equipment, and in particular relates to a tank packing siphon extraction device. Background Technology

[0002] In a pure water purification system, sand tanks, activated carbon tanks, and resin tanks are the three core pretreatment filtration devices. Each plays a specific role, working together to protect the delicate downstream membrane elements (such as reverse osmosis membranes) and ensure the quality of the final product water. The sand tank is filled with quartz sand, typically composed of layers of sand with varying particle sizes, gradually increasing in size from top to bottom. The activated carbon tank is filled with activated carbon granules, usually coconut shell charcoal or coal-based charcoal. The resin tank is filled with ion exchange resin. These tanks require regular maintenance, including replacing the internal packing material based on water quality and usage.

[0003] Replacing the internal packing material requires manual operation by workers. Workers must enter the tank and use tools such as long-handled spoons to remove the material to be replaced. However, contaminants on the workers' clothing can contaminate the tank interior, potentially causing quartz sand to clump (forming hard lumps), suspended solids and colloids to coat the surface of activated carbon particles, clogging the micropores of the activated carbon, and resin breakage, thus affecting the resin's ion exchange efficiency. Utility Model Content

[0004] This utility model provides a tank packing siphon extraction device. The feed pipe is inserted into the solid-liquid mixture inside the tank. While the water storage bladder releases water, it generates negative pressure in the water storage bladder to siphon the solid-liquid mixture inside the tank into the water storage bladder, and then discharge it from the first discharge pipe. This avoids workers from entering the tank and reduces the amount of pollution entering the tank.

[0005] This utility model provides a tank packing siphon extraction device, including an internally connected feed pipe, a water storage air bag and a first discharge pipe;

[0006] One end of the feed pipe is located inside the tank, and the other end is located outside the tank and is detachably connected to the first port of the water storage airbag; the second port of the water storage airbag is detachably connected to one end of the first discharge pipe;

[0007] The first port is located near the top of the water-retaining airbag; the second port is located near the bottom of the water-retaining airbag.

[0008] The height above the ground of the end of the first discharge pipe furthest from the second port is less than the height above the ground of the end of the feed pipe furthest from the water storage airbag.

[0009] Optionally, the volume of the water storage airbag is larger than the volume of the feed pipe.

[0010] Optionally, the sum of the cavity volume of the water storage airbag and the cavity volume of the first discharge pipe is greater than the cavity volume of the feed pipe.

[0011] Optionally, the tank packing siphon extraction device provided by this utility model further includes a second discharge pipe; one end of the second discharge pipe is detachably connected to the end of the first discharge pipe away from the water storage air bag, and the other end is provided with a first valve;

[0012] The second discharge pipe is provided with a water inlet pipe connected to the second discharge pipe on its side near the first discharge pipe; the water inlet pipe is provided with a second valve and is detachably connected to a water injection pipe.

[0013] Optionally, a variable diameter connector is fixedly connected to the end of the water injection pipe away from the second valve.

[0014] Beneficial effects:

[0015] This utility model provides a tank packing siphon extraction device, wherein one end of the feed pipe extends into the solid-liquid mixture inside the tank. When the water storage bladder releases water, a negative pressure is generated in the water storage bladder. The feed pipe, the water storage bladder, and the first discharge pipe are internally connected. The solid-liquid mixture is siphoned into the water storage bladder through the feed pipe and then discharged from the first discharge pipe, avoiding the entry of operators into the tank and thus reducing the entry of pollution sources into the tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] As described in the background section, when workers enter the tank, the pollutants on their bodies come into contact with the inside of the tank and contaminate it. This can cause the quartz sand to clump together (forming hard lumps), and suspended solids and colloids to coat the surface of the activated carbon particles, clogging the micropores of the activated carbon and causing the resin to break down, thus affecting the resin's ion exchange efficiency.

[0023] Therefore, in order to solve the above problems, such as Figure 1 and Figure 3 As shown, this utility model embodiment provides a tank packing siphon extraction device, including an internally connected feed pipe 1, a water storage airbag 2, and a first discharge pipe 3.

[0024] One end of the feed pipe 1 is located inside the tank, and the other end is located outside the tank and is detachably connected to the first port 21 of the water storage airbag 2; the second port 22 of the water storage airbag 2 is detachably connected to one end of the first discharge pipe 3.

[0025] The first port 21 is located near the top of the water-storing airbag 2; the second port 22 is located near the bottom of the water-storing airbag 2.

[0026] like Figure 2 As shown, the height of the end of the first discharge pipe 3 away from the second port 22 is less than the height of the end of the feed pipe 1 away from the water storage airbag 2.

[0027] When using the tank filling siphon extraction device provided by this utility model, the end of the first discharge pipe 3 away from the water storage air bag 2 is detachably connected to a water supply pipe. The water pressure of the water supply pipe is sufficient to transport the water in the water supply pipe to the water storage air bag 2. If there is only solid filling material inside the tank, the water supply pipe can be used to fill the tank with water, so that the solid filling material inside the tank mixes with the water to form a solid-liquid mixture.

[0028] One end of the feed pipe 1 is placed below the liquid surface of the solid-liquid mixture in the tank. The end of the first discharge pipe 3 away from the water storage bladder 2 is disconnected from the water supply pipe. The water in the water storage bladder 2 flows out through the first discharge pipe 3. At the same time as the water flow is released, the internal cavity of the water storage bladder 2 generates negative pressure to siphon the solid-liquid mixture in the tank into the water storage bladder 2, and then discharge it from the first discharge pipe 3.

[0029] In order for the negative pressure generated inside the water storage airbag 2 to draw in the solid-liquid mixture inside the tank, for example, the volume of the water storage airbag 2 is greater than the volume of the inlet pipe 1, or the sum of the volume of the water storage airbag 2 and the volume of the first outlet pipe 3 is greater than the volume of the inlet pipe 1.

[0030] For example, the tank packing siphon extraction device provided by this utility model further includes a second discharge pipe 4; one end of the second discharge pipe 4 is detachably connected to the end of the first discharge pipe 3 away from the water storage airbag 2, and the other end is provided with a first valve 41.

[0031] The second discharge pipe 4 is provided with a water inlet pipe 42 connected to the second discharge pipe 4 on the side near the first discharge pipe 3; the water inlet pipe 42 is provided with a second valve 43 and is detachably connected to a water injection pipe 5.

[0032] The second discharge pipe 4 and the water injection pipe 5 are set up to separate the water injection pipe and the discharge pipe, so as to avoid the discharge and water injection sharing a single pipe, that is, to prevent the outlet of the discharge pipe (i.e. the second discharge pipe 4) from contaminating the water supply pipe.

[0033] One end of the water injection pipe 5 is detachably connected to a water supply pipe. When injecting water, the first valve 41 is closed to prevent water from flowing out of the second discharge pipe 4 during the injection process. The second valve 43 is opened to inject water into the tank and / or the water storage bladder 2. After the water is injected to meet the siphon condition, the second valve 43 is closed to prevent the solid-liquid mixture from entering the water injection pipe 5 during discharge. One end of the water injection pipe 5 (the water injection end) can be detached from or not detached from the water supply pipe according to the actual situation.

[0034] When discharging, the first valve 41 is opened, and the water in the water storage bladder 2 flows out through the first discharge pipe 3 and the second discharge pipe 4 (to the container storing the solid-liquid mixture). At the same time as the water flow is released, the internal cavity of the water storage bladder 2 generates negative pressure to siphon the solid-liquid mixture in the tank into the water storage bladder 2, and then discharges it from the second discharge pipe 4 (to the container storing the solid-liquid mixture), thus completing the cleaning of the filling material inside the tank.

[0035] To accommodate water supply pipes of different diameters, a variable diameter connector 51 is fixedly connected to the end of the water injection pipe 5 away from the second valve 43.

[0036] In summary, this embodiment provides a tank packing siphon extraction device. One end of the feed pipe 1 extends into the solid-liquid mixture inside the tank. When the water storage bladder 2 releases water, a negative pressure is generated in the water storage bladder 2. The feed pipe 1, the water storage bladder 2, and the first discharge pipe 3 are internally connected. The solid-liquid mixture is siphoned into the water storage bladder 2 through the feed pipe 1 and then discharged from the first discharge pipe 3, avoiding the entry of operators into the tank and thus reducing the entry of pollution sources into the tank.

Those skilled in the art will understand that various equivalent substitutions, modifications, or improvements can be made to the technical solutions and implementation methods of the present invention without departing from the spirit and scope of the present invention, and all such modifications and improvements fall within the scope of the present invention.
