Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, specifically a bypass water treatment device. Background Technology

[0002] A search revealed that the existing technology with announcement number CN221943956U operates as follows: During normal operation, the inlet and outlet valves are synchronously open, while the backwash inlet and backwash drain valves are simultaneously closed. When the set time in the control cabinet 4 is reached, the system begins backwashing, with the inlet and outlet valves synchronously closed, and the backwash inlet and backwash drain valves simultaneously open. This mechanical linkage ensures synchronization of the inlet and outlet valves and the backwash inlet and outlet valves, reducing the frequency of malfunctions caused by valve issues. The entire system operates automatically through the control cabinet. The entire system is connected to the main pipeline via a bypass. The inlet, outlet 7, backwash inlet, and backwash drain 12 of the packing tank 9 are each connected to four manual butterfly valves. These four manual butterfly valves are connected to an actuator via mechanical linkages, and the actuator drives the four valves through the mechanical linkages.

[0003] Therefore, it can be seen that the system mainly utilizes a centrifugal pump to pump water into the packing tank 9, and then uses corresponding valves to open or close to complete water purification or backwashing of the system. This necessitates the installation of a pre-filter before the water enters the pump; otherwise, impurities in the water will cause severe wear on the pump's internal impeller. As is well known, the core equipment in a water treatment system is the water pump. Water pumps are not only costly to operate, but also prone to damage at high speeds. Furthermore, adding a pre-filter results in high pressure loss, easy clogging, and difficulty in water intake. Adding an extra pre-filter not only increases the overall cost of the water treatment system, but also requires frequent replacement of the filter media, leading to increased maintenance frequency. Utility Model Content

[0004] The purpose of this invention is to provide a bypass water treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bypass water treatment device, comprising a base, a water pump and a purification tank mounted on the base, and a water circuit control component connected to the purification tank; the water circuit control component includes an inlet pipe, with a first water pipe and a second water pipe on one side of the inlet pipe; one end of the first water pipe is connected to a first connecting pipe via a first valve, and the end of the first connecting pipe away from the first valve is connected to a second valve; the second valve is connected to the inlet of the water pump via a pipe, and the first connecting pipe is connected to a first connecting part on the purification tank via a first branch pipe; one end of the second water pipe is connected to the second connecting pipe via a third valve, and the end of the second connecting pipe away from the third valve is connected to a fourth valve, and the second connecting pipe is connected to a second connecting part on the purification tank via a second branch pipe; during purification, the first valve and the fourth valve are closed, and the second valve and the third valve are open, water flows from the inlet pipe to the second connecting part, then flows out through the first connecting part, and flows along the pipe to the water pump;

[0006] During backwashing, the first valve and the fourth valve are opened, while the second valve and the third valve are closed. Water flows from the inlet pipe to the first connection, then flows out from the second connection on the purification tank, and finally is discharged through the fourth valve.

[0007] As a preferred technical solution of this utility model, it further includes a linkage transmission mechanism, which includes a first arm mounted on the first valve, a first swing arm mounted on the second valve, a second arm mounted on the third valve, and a second swing arm mounted on the fourth valve; a connecting rod is provided between the first arm, the first swing arm, the second arm, and the second swing arm.

[0008] As a preferred technical solution of this utility model: the fourth valve is further provided with a driving component, and the driving component causes the linkage transmission mechanism to work.

[0009] As a preferred technical solution of this utility model: the purification tank is provided with a water distribution pipe inside, and the water distribution pipe is connected to the first connecting part.

[0010] As a preferred technical solution of this utility model: the purification tank is further provided with a water collection pipe, and the water collection pipe is connected to the second connecting part.

[0011] As a preferred technical solution of this utility model: the purification tank is filled with a water purification filler, and the filler completely covers the water collection pipe.

[0012] The beneficial effects of this utility model by adopting the above technical solution are as follows: 1. Since the equipment uses water circuit control components to control the direction of water flow, for example, during purification: water flows into the purification tank through the inlet pipe, and then the water pump draws water from inside the purification tank, and finally pumps the water out through the water pump. Therefore, the water in the system is purified before flowing to the water pump, which can greatly reduce the damage to the water pump caused by impurities in the water and help extend the service life of the water pump. In particular, the water treatment system of this equipment does not require an additional pre-filter, which can reduce the operating cost of the equipment and the number of maintenance times.

[0013] 2. During backwashing, the water flows into the inlet pipe, then into the second connection, and then into the purification tank. The water in the purification tank is then discharged through the first connection. Therefore, the water pump does not work while backwashing is being performed, which reduces the energy consumption of the equipment and extends the service life of the water pump.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0021] Please see Figure 1-5 This utility model provides an embodiment of a bypass water treatment device, including a base 1, a water pump 4 and a purification tank 2 mounted on the base 1, and a water circuit control component 3 connected to the purification tank 2. The water circuit control component 3 includes an inlet pipe 35, with a first water pipe 37 and a second water pipe 311 on one side of the inlet pipe 35. One end of the first water pipe 37 is connected to a first connecting pipe 38 via a first valve 31, and the end of the first connecting pipe 38 away from the first valve 31 is connected to a second valve 32. The second valve 32 is connected to the inlet of the water pump 4 via a pipe 30, and the first connecting pipe 38 is connected to a first connecting part 6 on the purification tank 2 via a first branch pipe 36. One end of the second water pipe 311 is connected to a third valve 311. 3 is connected to a second connecting pipe 39, the end of which is away from the third valve 33 is connected to a fourth valve 34, and the second connecting pipe 39 is connected to a second connecting part 7 on the purification tank 2 via a second branch pipe 310. During purification, the first valve 31 and the fourth valve 34 are closed, and the second valve 32 and the third valve 33 are open. Water flows from the inlet pipe 35 to the second connecting part 7, then flows out through the first connecting part 6, and flows along the pipe 30 to the water pump 4. During backwashing, the first valve 31 and the fourth valve 34 are open, and the second valve 32 and the third valve 33 are closed. Water flows from the inlet pipe 35 to the first connecting part 6, then flows out through the second connecting part 7 on the purification tank 2, and is discharged through the fourth valve 34.

[0022] In summary, because the equipment utilizes the water circuit control component 3 to control the direction of water flow, for example during purification: water flows into the purification tank 2 through the inlet pipe 35, then the water pump 4 draws water from inside the purification tank 2, and finally pumps the water out through the water pump 4. Therefore, the water in this system is purified before flowing to the water pump 4, which can greatly reduce the damage to the water pump caused by impurities in the water and help extend the service life of the water pump. In particular, the water treatment system of this equipment does not require an additional pre-filter, which can reduce the operating cost of the equipment and the number of maintenance times.

[0023] In addition, during backwashing, the water flows into the inlet pipe 35 and then into the second connection part 7, and then into the purification tank 2 through the second connection part 7. The water that has entered the purification tank 2 is then discharged through the first connection part 6. Therefore, the water pump 4 of the equipment does not work while backwashing is being performed, which can reduce the energy consumption of the equipment and the service life of the water pump 4.

[0024] Furthermore, to facilitate the synchronous control of the opening and closing of the four valves, the device also includes a linkage mechanism 312. Specifically, the linkage mechanism 312 includes a first arm 314 mounted on the first valve 31, a first swing arm 316 mounted on the second valve 32, a second arm 315 mounted on the third valve 33, and a second swing arm 317 mounted on the fourth valve 34. A connecting rod 318 is provided between the first arm 314, the first swing arm 316, the second arm 315, and the second swing arm 317 to shorten the opening time of the four valves.

[0025] Furthermore, since the fourth valve 34 is also equipped with a drive element 313, which drives the linkage transmission mechanism 312 to operate, the device can automatically cause the four valves to complete their respective actions via the drive element 313.

[0026] The drive unit 313 is preferably a partially rotary valve electric actuator, and the first valve 31, the second valve 32, the third valve 33 and the fourth valve 34 are all butterfly valves, and the first arm 314, the second arm 315, the first swing arm 316 and the second swing arm 317 are all mounted on the valve stem of the butterfly valve.

[0027] Based on the above solution, since the purification tank 2 is equipped with a water distribution pipe 8, which is connected to the second connecting part 7, and the outlet of the water distribution pipe 8 is upward-facing, the water can flow from top to bottom when the device is in water purification mode, thus facilitating water dispersion.

[0028] Furthermore, since the purification tank 2 is also equipped with a water collection pipe 5, and the water collection pipe 5 is connected to the first connecting part 6, the water collection pipe 5 can be used to collect water flow so that the water pump 4 can extract the water flow that enters the water collection pipe 5.

[0029] Furthermore, the purification tank 2 is filled with water-purifying filler material, which completely covers the water collection pipe 5. The filler material can be sand particles, activated carbon particles, or other materials that can trap suspended solids. The water collection pipe 5 consists of a main pipe with symmetrically arranged horizontal pipes along its radial direction. Both the horizontal pipes and the main pipe have openings to allow purified water to flow into the water collection pipe 5.

[0030] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
