Description

Technical Field

[0001] The present application relates to the technical field of water purification, and in particular to a water treatment device. Background Art

[0002] In the calcium chloride process, water treatment equipment mainly plays the role of raw water purification, hardness removal and water quality regulation. At the front end of the treatment, a precipitant needs to be added to the raw water to help the impurities in the raw water settle in the sedimentation tank. After the sedimentation tank has been used for a long time, it is necessary to suspend the sedimentation, drain the upper water, and then clean the sediment at the bottom of the tank. Since the sedimentation process is interrupted, the overall water treatment efficiency is affected. Utility Model Content

[0003] In order to make up for the above deficiencies, the present application provides a water treatment device, aiming to improve the problems mentioned in the above background technology.

[0004] An embodiment of the present application provides a water treatment device, including a sedimentation tank, a deflection plate, a translation member and a scraper member. The deflection plate array is in the sedimentation tank, the translation member drives the scraper member to scrape along the bottom of the sedimentation tank, the scraper member and one end of the bottom of the sedimentation tank form a channel, and a mud suction pipe is provided at one end of the channel.

[0005] In a specific embodiment, water flow troughs are provided at both ends of the sedimentation tank.

[0006] In the above implementation process, raw water flows into the sedimentation tank from one end. The sediment slows down the flow rate due to the obstruction of the deflection plate and then settles at the bottom of the sedimentation tank. The water continues to flow from the upper layer of the sedimentation tank and is discharged from the water flow trough at the other end, achieving the effect of dynamic sedimentation.

[0007] In a specific embodiment, the deflection plate includes an arc-shaped baffle, the baffle array is hinged in the sedimentation tank, and the bottom end of the baffle is movably attached to the bottom of the sedimentation tank.

[0008] In the above implementation process, the sediment hits the baffle along with the water flow, thereby slowing down the flow rate and then settling at the bottom of the baffle. Multiple baffles can improve the sedimentation effect.

[0009] In a specific embodiment, the deflection plate further includes a deflection motor and a chain mechanism. The deflection motor is arranged on the outer wall of the sedimentation tank, and the output end of the deflection motor is connected to all the baffle shafts through the chain mechanism.

[0010] In the above implementation process, the deflection motor drives all baffles to deflect through the chain mechanism, thereby making room for the scraper member, making it easier for the scraper member to move from one end to the other along the bottom of the sedimentation tank, and then return to the initial position. After the baffle is deflected, it still has a certain effect of hindering the water flow, so the sedimentation process can continue.

[0011] In a specific embodiment, the scraper member includes an upper arc plate and a lower arc plate, the upper arc plate is installed on the translation member, the lower arc plate is hinged to the upper arc plate, and the lower end of the lower arc plate is movably attached to the bottom wall of the sedimentation tank.

[0012] In the above implementation process, when the scraper moves toward the mud suction pipe, the lower arc plate moves against the bottom of the sedimentation tank, thereby scraping off the sediment. When the scraper returns, the lower arc plate is pushed and deflected by the water flow to leave the bottom of the tank, avoiding the situation where the sediment on the bottom of the tank is scraped back to the initial position.

[0013] In a specific embodiment, the translation member includes a screw rod and a slider, the slider is threadedly connected to the screw rod, the screw rod is rotationally connected to the sedimentation tank, and the slider is fixedly connected to the upper arc plate.

[0014] In a specific implementation manner, two ends of the upper arc plate are respectively fixedly connected with a slider, and each slider is screwed with a screw rod.

[0015] In the above implementation process, the two screws rotate to drive the scraper member to move back and forth stably.

[0016] In a specific implementation, the translation member further includes a double-headed motor and a gear set, and the two output ends of the double-headed motor are respectively connected to the two screw shafts through the corresponding gear sets.

[0017] In the above implementation process, the double-headed motor drives the two screws to rotate synchronously through the two gear sets, thereby driving the scraper member to move back and forth stably.

[0018] In a specific embodiment, slide grooves adapted to the sliding blocks are provided on both sides of the sedimentation tank.

[0019] In the above implementation process, the slide groove is used to accommodate the screw rod and the slider to avoid structural interference with the baffle, so that the baffle can better fit the side wall of the sedimentation tank, which is beneficial to blocking the water flow.

[0020] In a specific embodiment, a water supply pipe is provided at the other end of the channel, and the water supply pipe is connected to the water flow trough at the rear end.

[0021] In the above implementation process, when the external mud pumping equipment extracts sediment through the mud pumping pipe, negative pressure appears in the channel, and the precipitated water is replenished into the channel through the water supply pipe, which helps to increase the water flow speed in the channel and improve the mud pumping effect.

[0022] Compared with the prior art, the beneficial effects of the present application are: the deflector plate is used to slow down the water flow to help sedimentation, and is slightly lifted when cleaning the dirt, and then the translation part drives the scraper part to scrape the sludge along the bottom of the sedimentation tank to one end of the sedimentation tank and form a channel, and the sludge in the channel is directly pumped away through the mud suction pipe, and finally the scraper part and the deflector plate are reset, thereby achieving the effect of removing sediment without interrupting the sedimentation process and improving the overall treatment efficiency of the water treatment equipment.

DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0030] See also Figure 1-Figure 4The present application provides a water treatment device, including a sedimentation tank 10, a deflection plate 20, a translation member 30 and a scraper member 40. The deflection plate 20 is arrayed in the sedimentation tank 10, and the translation member 30 drives the scraper member 40 to scrape along the bottom of the sedimentation tank 10. The scraper member 40 and one end of the bottom of the sedimentation tank 10 form a channel, and a mud extraction pipe 50 is provided at one end of the channel. The deflection plate 20 is used to slow down the water flow to help sedimentation, and is slightly lifted when cleaning. Then the translation member 30 drives the scraper member 40 to scrape the sludge along the bottom of the sedimentation tank 10 to one end of the sedimentation tank 10 and form a channel. The sludge in the channel is directly extracted through the mud extraction pipe 50. Finally, the scraper member 40 and the deflection plate 20 are reset, so as to achieve the effect of removing sediment without interrupting the sedimentation process, and improve the overall treatment efficiency of the water treatment equipment.

[0031] See also Figure 1-Figure 4 , both ends of the sedimentation tank 10 are provided with water troughs 60. Raw water flows into the sedimentation tank 10 from one end, and the sediment slows down the flow rate under the obstruction of the deflection plate 20, and then settles at the bottom of the sedimentation tank 10, while the water continues to flow from the upper layer of the sedimentation tank 10 through the water trough 60 at the other end to be discharged, achieving the effect of dynamic sedimentation.

[0032] See also Figure 1-Figure 4 The deflection plate 20 includes an arc-shaped baffle 21, and the baffle 21 array is hinged in the sedimentation tank 10, and the bottom of the baffle 21 is movably attached to the bottom of the sedimentation tank 10. The sediment hits the baffle 21 with the water flow, thereby slowing down the flow rate and then settling at the bottom of the baffle 21. Multiple baffles 21 can improve the sedimentation effect.

[0033] See also Figure 1-Figure 4 The deflection plate 20 further includes a deflection motor 22 and a chain mechanism 23. The deflection motor 22 is arranged on the outer wall of the sedimentation tank 10. The output end of the deflection motor 22 is connected to the shafts of all the baffles 21 through the chain mechanism 23. The deflection motor 22 drives all the baffles 21 to deflect through the chain mechanism 23, thereby making room for the scraper member 40, so that the scraper member 40 moves from one end to the other end along the bottom of the sedimentation tank 10, and then returns to the initial position. After the baffle 21 is deflected, it still has a certain effect of hindering the water flow, so the sedimentation process can continue.

[0034] See also Figure 1-Figure 4 The scraper member 40 includes an upper arc plate 41 and a lower arc plate 42. The upper arc plate 41 is mounted on the translation member 30, and the lower arc plate 42 is hinged to the upper arc plate 41. The lower end of the lower arc plate 42 is movably attached to the bottom wall of the sedimentation tank 10. When the scraper member 40 moves toward the mud pumping pipe 50, the lower arc plate 42 moves against the bottom of the sedimentation tank 10 to scrape the sediment clean. When the scraper member 40 returns, the lower arc plate 42 is pushed and deflected by the water flow to leave the bottom of the tank, avoiding the situation where the sediment on the bottom of the tank is scraped back to the initial position.

[0035] See also Figure 1-Figure 4 The translation member 30 includes a screw rod 31 and a slider 32. The slider 32 is screwed to the screw rod 31. The screw rod 31 is rotatably connected to the sedimentation tank 10. The slider 32 is fixedly connected to the upper arc plate 41. A slider 32 is fixedly connected to both ends of the upper arc plate 41. A screw rod 31 is screwed to each slider 32. The two screw rods 31 rotate to drive the scraper member 40 to reciprocate stably.

[0036] See also Figure 1-Figure 4 The translation member 30 also includes a double-headed motor 33 and a gear set 34. The two output ends of the double-headed motor 33 are respectively connected to the two screw rods 31 through the corresponding gear sets 34. The double-headed motor 33 drives the two screw rods 31 to rotate synchronously through the two gear sets 34, thereby driving the scraper member 40 to reciprocate stably.

[0037] See also Figure 1-Figure 4 , both sides of the sedimentation tank 10 are provided with chutes adapted to the slider 32. The chutes are used to accommodate the screw rod 31 and the slider 32 to avoid structural interference with the baffle 21, so that the baffle 21 can better fit the side wall of the sedimentation tank 10, which is conducive to blocking the water flow.

[0038] See also Figure 1-Figure 4 A water supply pipe 70 is provided at the other end of the channel, and the water supply pipe 70 is connected to the water flow trough 60 at the rear end. When the external mud pumping equipment extracts sediment through the mud pumping pipe 50, negative pressure appears in the channel, and the settled water is replenished into the channel through the water supply pipe 70, which helps to increase the water flow speed in the channel and improve the mud pumping effect.

[0039] The working principle of the water treatment equipment is as follows: raw water flows into the sedimentation tank 10 from one end of the sedimentation tank 10, and the sediment hits the baffle 21 with the water flow, thereby slowing down the flow rate and then settling at the bottom of the baffle 21. When cleaning is required, the deflection motor 22 drives all the baffles 21 to deflect through the chain mechanism 23, thereby making room for the scraper member 40. The double-headed motor 33 drives the two screws 31 to rotate synchronously through two gear sets 34, thereby driving the scraper member 40 to move from the initial position at one end of the sedimentation tank 10 toward the sewage pipe. The lower arc plate 42 moves against the bottom of the sedimentation tank 10, thereby pushing the sludge at the bottom to the sewage pipe. The upper arc plate 41 and the lower arc plate 42 contact the bottom corners of the sedimentation tank 10 to form a horizontal channel. When the external mud pumping equipment extracts the sediment through the mud pumping pipe 50, a negative pressure appears in the channel. The precipitated water is replenished into the channel through the water supply pipe 70, which helps to increase the water flow speed in the channel and improve the mud extraction effect. After that, when the translation member 30 drives the scraper member 40 to return, the lower arc plate 42 is pushed and deflected by the water flow to leave the bottom of the pool, avoiding the situation where the sediment at the bottom of the pool is scraped back to the initial position. Finally, all the baffles 21 can contact the bottom of the sedimentation tank 10 again. In summary, the deflection plate 20 is used to slow down the water flow to help sedimentation, and is slightly lifted during cleaning. Then the translation member 30 drives the scraper member 40 along the bottom of the sedimentation tank 10 to scrape the sludge to one end of the sedimentation tank 10 and form a channel, and the sludge in the channel is directly extracted through the mud extraction pipe 50. Finally, the scraper member 40 and the deflection plate 20 can be reset, thereby achieving the effect of removing sediment without interrupting the sedimentation process and improving the overall treatment efficiency of the water treatment equipment.
