Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment devices, and in particular relates to a water treatment tank. Background Technology

[0002] The existing water treatment tank inlet and outlet designs cannot fully utilize the tank's internal volume, and the internal filter media cannot play its full role. This is mainly reflected in the following aspects: the water path from the inlet to the outlet is prone to short circuits; there is no water distribution device at the inlet, resulting in uneven distribution of the incoming water flow; the filter media at the bottom of the tank does not participate in the water flow, resulting in wasted space at the bottom of the tank; and no filter grilles are added to the inlet and outlet, which cannot effectively prevent leakage of internal filter media. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a water treatment tank.

[0004] To solve the above problems, the present invention adopts the following technical solution:

The inlet pipe and drain pipe are horizontally arranged, with one end extending through the side wall of the tank body into the interior. The ends of the inlet pipe and drain pipe located inside the tank body are sealed and connected to the side wall of the tank body. The other end of the inlet pipe is open and located outside the tank body. The inner portion of the inlet pipe has several inlet holes on its wall. The other end of the drain pipe is open and located outside the tank body. The inner portion of the drain pipe has several drain holes on its wall. Neither the inlet holes nor the drain holes can allow filter media particles to pass through. The sum of the areas of all the inlet holes is equal to the cross-sectional area of ​​the inlet pipe.

[0006] Preferably, the water inlet pipe is located at the bottom of the tank, and the drain pipe is located at the top of the tank.

[0007] Preferably, the sum of the areas of all the drain holes is equal to 5 to 10 times the cross-sectional area of ​​the drain pipe.

[0014] The beneficial effects of this utility model are:

[0015] Compared with existing technologies, the advantages of this utility model are:

[0016] This utility model provides a water treatment tank with a more scientific structure and layout that better meets the slow-release characteristics of solid water treatment agents. It changes the water inlet direction, makes full use of the space at the bottom of the tank, and, through the design of the grid water passage area, prevents leakage of internal filter media, ensuring uniform water inlet and stable water flow rate.

Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0018] 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.

[0019] like Figure 1 As shown, this utility model provides a technical solution: a water treatment tank, including a tank body 1, an inlet pipe 2, and a drain pipe 3. The tank body 1 is hollow inside for holding filter media. The inlet pipe 2 and the drain pipe 3 are horizontally arranged, with one end penetrating through the side wall of the tank body 1 and extending into the interior of the tank body 1. The ends of the inlet pipe 2 and the drain pipe 3 located inside the tank body 1 are sealed and connected to the side wall of the tank body 1. The other end of the inlet pipe 2 is open and located outside the tank body 1. The wall of the inlet pipe 2 located inside the tank body 1 is provided with a plurality of inlet holes 21. The other end of the drain pipe 3 is open and located outside the tank body 1. The wall of the drain pipe 3 located inside the tank body 1 is provided with a plurality of drain holes 31. Neither the inlet holes 21 nor the drain holes 31 can pass through filter media particles. The sum of the hole areas of all the inlet holes 21 is equal to the cross-sectional area of ​​the inlet pipe 2.

[0020] This utility model provides several inlet holes 21 and outlet holes 31 on the walls of the inlet pipe 2 and outlet pipe 3, respectively. The inlet holes 21 and outlet holes 31 are not allowed to pass filter media particles, thereby preventing leakage of internal filter media and ensuring uniform water distribution. The design ensures that the sum of the hole areas of all the inlet holes 21 on the inlet pipe 2 is equal to the cross-sectional area of ​​the inlet pipe 2, so that the water flow rate is stable and the problem of short circuits easily occurring in the water path from the inlet to the outlet is solved.

[0021] Furthermore, the water inlet pipe 2 is located at the bottom of the tank 1, and the drain pipe 3 is located at the top of the tank 1, so that the water inlet fills the entire tank 1 from the bottom and then is discharged from the drain pipe 3, so that the water inlet can fully react with all the scale-inhibiting filter media in the tank 1, thereby improving the filtration effect.

[0022] Furthermore, the sum of the hole areas of all the drain holes 31 is equal to 5 to 10 times the cross-sectional area of ​​the drain pipe 3, which increases the water flow area, reduces the possibility of water blockage, and extends the service life and maintenance cycle of the tank.

[0023] Since most of the filter media are spherical particles, the circular inlet holes 21 and outlet holes 31 are easily blocked by the filter media particles. Furthermore, the inlet holes 21 and outlet holes 31 are both strip-shaped holes, which avoids the inlet holes 21 and outlet holes 31 being blocked by the filter media particles.

[0024] Furthermore, the top of the tank 1 is provided with a feeding port 11 with a sealing cap, which facilitates the addition of filter material into the tank 1.

[0025] Furthermore, the bottom of the tank 1 is provided with a discharge port 12 with a sealing cap, which facilitates the discharge and replacement of the scale-inhibiting filter material inside the tank 1.

[0026] Furthermore, all water inlets 21 are located at the lower semicircle of the water inlet pipe 2. When water enters, the water will impact downwards, allowing the scale-inhibiting filter material at the bottom of the tank 1 to come into contact with the water, thereby achieving a filtering effect and increasing the filtration area.

[0027] Furthermore, both the inlet pipe 2 and the outlet pipe 3 are provided with a connecting flange 4 at one end located outside the tank body 1, which facilitates the connection of the inlet pipe 2 and the outlet pipe 3 with external water inlet and outlet.

[0028] Furthermore, the bottom of the tank 1 is provided with support legs 5 for supporting the tank 1, thereby supporting the tank 1 and facilitating the placement of a container below the discharge port 12 at the bottom of the tank 1 to hold the discharged filter material.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
