Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to a water treatment device with controllable flow rate. Background Art

[0002] With the rapid development of urbanization and industrialization, the problem of water pollution has become increasingly serious. How to improve the urban water environment is the key to ensuring social and economic development.

[0003] During the water treatment process, the conveying water flow of the water supply device generally gradually decreases as the water level drops, which makes the water supply flow of the water treatment device relatively unstable. And the water treatment effect is often directly related to the flow rate. Once the flow rate is too fast, it is easy to cause insufficient contact time between the water treatment medium and the pollutants in the water, affecting the water treatment effect; while if the flow rate is too slow, it will lead to a decline in water treatment capacity and low water treatment efficiency. Content of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide a water treatment device with controllable flow rate.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A water treatment device with controllable flow rate includes a sedimentation tank. A conveying pipe is installed on the sedimentation tank. A flow stabilizing component is arranged in the conveying pipe. The conveying pipe is provided with an outwardly expanding flared section. The flow stabilizing component includes a plug arranged inside the flared section. The plug can move close to the flared section to reduce the gap between the plug and the flared section.

[0007] Preferably, the flow stabilizing component further includes a mounting plate installed in the conveying pipe. A connecting column is fixed on the mounting plate. A connecting rod extending outward is slidably installed in the connecting column. The plug is fixed on the connecting rod. An abutting rod abutting against the plug is rotatably installed on the outer periphery of the connecting column. The abutting rod can rotate and abut against and push the plug to move close to the flared section. A baffle is fixed on the abutting rod.

[0008] Preferably, a fixing plate is fixedly installed on the connecting column. The abutting rod is rotatably installed on the fixing plate through a rotating shaft. A connecting rod is fixed on the abutting rod. The baffle is installed on the connecting rod.

[0009] Preferably, the plug is conical. The number of the baffles is multiple and they are distributed on the outer periphery of the plug.

[0010] Preferably, an inner cavity is formed in the connecting column. A spring and a sliding rod are arranged in the inner cavity. One end of the spring abuts against the connecting column, and the other end of the spring abuts against the sliding rod. The connecting rod extends into the inner cavity and is fixed on the sliding rod.

[0011] Preferably, a rotating cover is installed on the connecting column, and the sliding rod can slide along the length direction of the inner cavity and abut against the rotating cover.

[0012] Preferably, a plug and a purification layer are sequentially arranged in the conveying pipe.

[0013] Preferably, a partition plate is arranged in the sedimentation tank, a filtration tank is arranged on the other side of the partition plate, and a mesh cover covering the port of the conveying pipe is installed in the filtration tank.

[0014] Preferably, a water inlet pipe and a drain pipe are installed on one side of the sedimentation tank in an up-and-down distribution, and a sloping plate is installed at the bottom of the sedimentation tank near the drain pipe.

[0015] The beneficial effects of the present utility model are as follows:

[0016] 1. By injecting sewage into the sedimentation tank, after the large-particle impurities in the sewage precipitate in the sedimentation tank, the sewage to be treated is conveyed outward through the conveying pipe. By arranging a plug in the conveying pipe that can reciprocate and adjust, when the sewage level in the sedimentation tank is relatively high, the sewage flow rate is relatively fast. At this time, the plug moves closer to the flared section of the conveying pipe to reduce the gap between the plug and the flared section, that is, to reduce the water conveyance diameter of the conveying pipe, thereby relatively reducing the sewage flow rate. And as the sewage level in the sedimentation tank drops, the sewage flow rate relatively slows down. At this time, the plug gradually moves away from the flared section to gradually increase the gap between the plug and the flared section, that is, to increase the water conveyance diameter of the conveying pipe, so that the sewage flow rate generally tends to be stable, to ensure the stable operation of the water treatment equipment and ensure the treatment effect and efficiency of the sewage.

[0017] 2. By setting the plug in a conical shape, the flow resistance of the plug to the sewage is small, and a rotating abutting rod is arranged on the back side of the plug, and a baffle is fixed on the abutting rod. The baffle has a large flow resistance to the sewage. When the sewage flow rate is fast, due to the large water flow resistance on the baffle, the baffle is stressed and drives the abutting rod to rotate, so that the abutting rod can push the plug to move closer to the flared section, thereby reducing the gap between the plug and the flared section, that is, reducing the water conveyance diameter of the conveying pipe. And as the sewage level drops, its flow rate gradually decreases, and the acting force of the abutting rod pushing the plug to move also gradually decreases. At this time, the plug gradually moves away from the flared section, thereby increasing the water conveyance diameter of the conveying pipe. Then, through the size of the sewage flow, the gap between the plug and the flared section is adaptively and automatically adjusted, and the output flow rate of the sewage is controlled within a stable range, so that the overall flow rate of the sewage output is relatively stable.

Specific embodiments

[0026] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments:

[0027] In the description of this specification, the orientation or positional relationship indicated by terms such as "upper", "lower", "left", "right", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or unit referred to must have a specific direction, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0028] As Figures 1 to 7 shown, a water treatment device with controllable flow rate includes a sedimentation tank 1. A conveying pipe 3 is installed on the sedimentation tank 1. A water inlet pipe 11 and a drain pipe 12 are installed on one side of the sedimentation tank 1 and are distributed up and down. The sewage to be treated is injected into the sedimentation tank 1 through the water inlet pipe 11 to precipitate the large particle impurities in the sewage in the sedimentation tank 1.

[0029] Further, a sloping plate 13 is installed at the bottom of the sedimentation tank 1 near the drain pipe 12. The sloping plate 13 is arranged obliquely towards the side of the drain pipe 12, so that the impurities sedimented to the bottom of the sedimentation tank 1 can be more conveniently flushed to the outside through the drain pipe 12.

[0030] The conveying pipe 3 conveys the sewage in the sedimentation tank 1 outwards. Specifically, a partition plate 14 is arranged in the sedimentation tank 1, and a filtration tank 2 is arranged on the other side of the partition plate 14. The partition plate 14 is used to separate the sedimentation tank 1 from the filtration tank 2. A water conveying pipe 141 is installed at the lower part of the partition plate 14. The water conveying pipe 141 is used to connect the sedimentation tank 1 and the filtration tank 2. The sewage in the sedimentation tank 1 is input into the filtration tank 2 through the water conveying pipe 141, and then the sewage is conveyed outwards through the filtration tank 2 and the conveying pipe 3.

[0031] The sewage is conveyed through the cooperation of the partition plate 14 and the water conveying pipe 141 to avoid directly conveying the sewage outwards through the sedimentation tank 1, which may cause the originally sedimented impurities to become turbid again with the conveyance of the sewage, affecting the subsequent sewage treatment.

[0032] Moreover, the water level of the sewage in the sedimentation tank 1 is generally injected relatively high. By batch-conveying the sewage to the filtration tank 2, the water level height when the filtration tank 2 conveys the sewage outwards can be reduced, so as to avoid the situation that the conveyed sewage is too high, resulting in too fast initial conveyance flow rate of the sewage, thereby affecting the stability of sewage treatment.

[0033] Further, a valve 142 is installed on the water conveying pipe 141. The valve 142 is used to close or open the water conveying pipe 141 to achieve the control of conveying the sewage into the filtration tank 2. A wire mesh cover 21 covering the port of the conveying pipe 3 is installed in the filtration tank 2. Through the setting of the wire mesh cover 21, floating impurities are prevented from blocking the conveying pipe 3.

[0034] A flow stabilizing component 4 is arranged in the conveying pipe 3. The conveying pipe 3 is provided with an outward-expanding flared section 31. The flow stabilizing component 4 includes a plug 43 arranged inside the flared section 31. The gap between the plug 43 and the flared section 31 is the caliber for the conveying pipe 3 to convey the sewage.

[0035] The plug 43 is arranged in a conical shape, and the conical tip of the plug 43 faces the side of the filtration tank 2. Thus, the flow resistance of the plug 43 to the sewage is relatively small.

[0036] The flow stabilizing component 4 further includes a mounting plate 41 installed in the conveying pipe 3. A flow hole 411 is opened on the mounting plate 41. The sewage is conveyed outwards through the flow hole 411. A connecting column 42 is fixed on the mounting plate 41. The connecting column 42 can be fixed on the side of the mounting plate 41 facing the filtration tank 2 by welding.

[0037] A connecting rod 431 extending outward is slidably installed inside the connecting column 42, and the plug 43 is fixed to the connecting rod 431. Specifically, an inner cavity 421 is formed inside the connecting column 42, and a spring 422 and a sliding rod 432 are arranged inside the inner cavity 421. The connecting rod 431 extends into the inner cavity 421 and is fixed to the sliding rod 432. A rotating cover 423 is installed on the connecting column 42. The sliding rod 432 can slide along the length direction of the inner cavity 421 and abut against the rotating cover 423, and the rotating cover 423 limits the sliding of the sliding rod 432 towards the plug 43 side.

[0038] One end of the spring 422 abuts against the connecting column 42, and the other end of the spring 422 abuts against the sliding rod 432. The elastic force of the spring 422 acts on the sliding rod 432 and pushes the plug 43 to move closer to the flared section 31. When the sewage in the conveying pipe 3 flows, the acting force of the water flow can act on the plug 43, and under the elastic force of the spring 422, the plug 43 can move closer to or away from the flared section 31 to adjust the size of the gap between the plug 43 and the flared section 31.

[0039] Furthermore, a resisting rod 442 abutting against the plug 43 is rotatably installed on the outer periphery of the connecting column 42. The resisting rod 442 extends obliquely and abuts against the back side of the plug 43, that is, the side of the plug 43 away from the filter tank 2. Specifically, a fixing plate 44 is fixedly installed on the connecting column 42, and the resisting rod 442 is rotatably installed on the fixing plate 44 through a rotating shaft 441 so that the resisting rod 442 can rotate through the rotating shaft 441. Furthermore, the resisting rod 442 can rotate and abut against and push the plug 43 to move closer to the flared section 31. By the plug 43 being able to move closer to the flared section 31, the gap between the plug 43 and the flared section 31 is reduced, that is, the water conveyance diameter of the conveying pipe 3 is reduced, and thus the flow rate of the sewage is relatively reduced.

[0040] A baffle 443 is fixed on the resisting rod 442. Specifically, a connecting rod 444 is fixed on the resisting rod 442, and the baffle 443 is installed on the connecting rod 444. The number of the baffles 443 is multiple and they are distributed on the outer periphery of the plug 43. The baffle 443 is set as a plane or is provided with a groove on the side facing the water flow direction to increase the resistance to the sewage flow.

[0041] When the sewage level in the sedimentation tank 1 (or the filter tank 2) is relatively high, the sewage flow rate is relatively fast. At this time, the resistance on the baffle 443 is relatively large (while the resistance of the plug 43 changes little with the sewage flow rate). Furthermore, the baffle 443 is stressed and drives the resisting rod 442 to rotate, so that the plug 43 moves closer to the flared section 31 of the conveying pipe 3 to reduce the gap between the plug 43 and the flared section 31, that is, the water conveyance diameter of the conveying pipe 3 is reduced to relatively reduce the sewage flow rate (compared with the sewage flow rate in the conveying pipe 3 close to the filter tank 2).

[0042] Specifically, the water flow velocity at the port of the delivery pipe 3 close to the filtration tank 2 is relatively fast. However, when passing between the plug 43 and the flared section 31, the water conveyance diameter of the delivery pipe 3 decreases, thereby controlling the flow velocity of the sewage in the subsequent delivery pipe 3 within the set range to prevent the sewage flow from being too fast, resulting in insufficient sewage treatment and affecting the water treatment effect.

[0043] As the sewage is conveyed, its water level gradually drops. At this time, the sewage flow velocity gradually decreases, and the acting force of the abutting rod 442 pushing the plug 43 to displace also gradually decreases. The plug 43 gradually moves away from the flared section 31 to gradually increase the gap between the plug 43 and the flared section 31, that is, to increase the water conveyance diameter of the delivery pipe 3. Furthermore, through the size of the sewage flow, the gap between the plug 43 and the flared section 31 is adaptively and automatically adjusted to control the output flow velocity of the sewage within a stable range.

[0044] Specifically, as the water level drops, its flow velocity also gradually decreases. However, by displacing the plug 43 to increase the gap between the plug 43 and the flared section 31, the flow velocity of the sewage flowing between the plug 43 and the flared section 31 is appropriately reduced to control the output flow velocity of the sewage in the subsequent delivery pipe 3 within the set range. Furthermore, as the sewage water level drops, the flow velocity of the sewage flowing between the plug 43 and the flared section 31 can basically remain stable, so as to achieve controllable sewage flow velocity, and then ensure the stability of the overall flow velocity of the sewage output, make the sewage flow velocity generally tend to be stable, ensure the stable operation of the water treatment equipment, ensure that the sewage can be fully treated, and improve the water treatment effect and efficiency.

[0045] A purification layer 32 is also provided in the delivery pipe 3. The plug 43 and the purification layer 32 are arranged in sequence. The purification layer 32 is used to filter and purify the sewage conveyed in the delivery pipe 3. The purification layer 32 is abutted and installed on the abutting ring 33 inside the delivery pipe 3. The abutting ring 33 is detachably installed in the delivery pipe 3. By removing the abutting ring 33, the purification layer 32 installed in the delivery pipe 3 can be replaced.

[0046] The purification layer 32 includes a gravel layer and an activated carbon layer. The particles of the gravel layer are relatively fine and can remove suspended particles in the sewage. The activated carbon layer can adsorb and remove pollutants that are not easily decomposed and degraded, such as heavy metals, toxic organic substances, etc. The sewage is preliminarily treated by the purification layer 32.

[0047] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
