Description

Technical Field

[0001] The invention belongs to the technical field of pure water acidification treatment, in particular to a pure water treatment device with an automatic acid addition function. Background Art

[0002] At present, in the process of pure water treatment in some chemical industries, the pH value of pure water will change with the change of raw water. When the pH value of raw water is high, the pH value of pure water obtained after passing through the pure water treatment system may be higher than the water requirement for chemical production, thereby affecting the quality of chemical products. Therefore, it is necessary to acidify the pure water to lower the pH value of the pure water.

[0003] In the prior art, the acidification treatment of pure water mostly involves passing the pure water to be acidified into a treatment container, and then manually passing acid liquid into the treatment container. When the acid liquid enters the treatment container, it mixes with the pure water, thereby reducing the pH value of the pure water. However, the manual introduction of acid liquid is time-consuming and labor-intensive, resulting in a relatively low acidification efficiency of the pure water. On the other hand, the acid liquid passed into the treatment container will contact the surface pure water in advance, and the inner layer of pure water cannot be quickly mixed with the acid liquid in a short time, resulting in a relatively long acidification time of the pure water, making the acidification efficiency of the pure water relatively low. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a pure water treatment device with an automatic acid addition function.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: A pure water treatment device with automatic acid adding function comprises a treatment box, a lifting assembly, a pumping assembly, a driving assembly and an acid delivery assembly. The top of the treatment box is provided with a water inlet. The lifting assembly is movably arranged inside the processing box. The driving assembly is installed on the inner wall of the processing box and is used to drive the lifting assembly to move up and down along the inside of the processing box. The acid delivery component is installed at the bottom of the lifting component. One end of the pumping component is connected to the top of the inner side of the processing box, and the other end is connected to the upper part of the lifting component, which is used to pump the acid in the external acid tank into the acid delivery component.

[0006] As a further improvement of the present invention: the lifting assembly comprises a lifting plate, and a cavity is formed inside the lifting plate. The pumping assembly includes a connecting tube, a piston sleeve and an annular piston block. The piston sleeve is fixedly installed on the top of the inner side of the processing box, the upper end of the connecting pipe extends into the interior of the piston sleeve, and the lower end is fixedly connected to the upper part of the lifting plate and communicated with the cavity, the annular piston block is fixedly arranged on the outer wall of the tube body of the connecting pipe located inside the piston sleeve, an acid inlet pipe is arranged on the top of the processing box, one end of the acid inlet pipe is connected to the external acid tank, and the other end is communicated with the piston sleeve, a one-way valve is arranged inside the connecting pipe and the acid inlet pipe, and the acid delivery component is arranged at the bottom of the lifting plate and communicated with the cavity.

[0007] As a further improvement of the present invention: the acid delivery assembly comprises a flexible acid delivery pipe belt and a coil spring, One end of the flexible acid conveying pipe belt is connected to the bottom of the lifting plate and communicated with the cavity. The coil spring is arranged on the outer wall of the flexible acid conveying pipe belt to drive the flexible acid conveying pipe belt to be in a curled state.

[0008] As a further improvement of the present invention: the size of the lifting plate is the same as the size of the inner cavity of the processing box, and a plurality of water filtering holes are opened on the lifting plate.

[0009] As a further improvement of the present invention: a cleaning assembly is also provided on the upper part of the lifting plate. When the lifting plate moves up along the inside of the treatment box and moves out of the pure water, the cleaning assembly is used to clean the impurities filtered out through the water filter holes.

[0010] As a further improvement of the present invention: an impurity storage groove is provided at the upper edge of the lifting plate. The cleaning assembly includes a scraper, an L-shaped sealing plate, a gear, a screw rod, an elastic member and a rack. The L-shaped sealing plate is arranged above the impurity storage groove for sealing the impurity storage groove, the bottom of the scraper is in contact with the upper surface of the lifting plate, one end of the screw rod is rotatably connected to the support plate, and the other end passes through the scraper and the L-shaped sealing plate in sequence and is fixedly connected to the gear, the screw rod is threadedly matched with the scraper, the support plate is fixedly arranged on the upper part of the lifting plate, the rack is fixedly installed on the inner wall of the processing box and can engage with the gear, one end of the elastic member is connected to the scraper, and the other end is connected to the L-shaped sealing plate.

[0011] As a further improvement of the present invention: the elastic member is a spring or a metal spring.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the embodiment of the present invention, initially, the lifting component is located at the lower inner side of the treatment box. When the pure water needs to be acidified, the pure water can be introduced into the treatment box from the water inlet, and then the driving component drives the lifting component to move upward along the inside of the treatment box.

At the same time, the pumping component is used to pump the acid in the external acid tank into the acid delivery component, and then the acid delivery component is transported to the pure water to achieve the acidification of the pure water. When the acid delivery component transports the acid into the pure water, since the acid delivery component continuously moves upward along the inside of the pure water, the acid delivered by the acid delivery component can enter the pure water at different depths, so that the acid can be quickly and fully mixed with the pure water, thereby improving the acidification effect and acidification efficiency of the pure water. Compared with the prior art, when the pure water is acidified, the pure water can be automatically acidified, and the added acid can be mixed into the different depths of the pure water by itself, thereby improving the acidification effect and acidification efficiency of the pure water.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0016] See also Figure 1 and Figure 2 The present embodiment provides a pure water treatment device with an automatic acid adding function, including a treatment box 10, a lifting component 20, a pumping component 40, a driving component 50 and an acid delivery component 60. The treatment box 10 is provided with a water inlet 101 at the top. The lifting component 20 is movably arranged inside the treatment box 10. The driving component 50 is installed on the inner wall of the treatment box 10 to drive the lifting component 20 to move up and down along the inside of the treatment box 10. The acid delivery component 60 is installed at the bottom of the lifting component 20. One end of the pumping component 40 is connected to the top of the inner side of the treatment box 10, and the other end is connected to the upper part of the lifting component 20, so as to pump the acid in the external acid liquid tank (not shown in the figure) into the inside of the acid delivery component 60.

[0017] Initially, the lifting component 20 is located at the lower inner side of the treatment box 10. When the pure water needs to be acidified, the pure water can be introduced into the treatment box 10 from the water inlet 101, and then the driving component 50 drives the lifting component 20 to move upward along the inside of the treatment box 10. When the lifting component 20 moves upward, it drives the acid delivery component 60 to move upward synchronously. At the same time, the pumping component 40 is used to pump the acid in the external acid tank into the acid delivery component 60, and then the acid delivery component 60 delivers it to the pure water to achieve the acidification of the pure water. When the acid delivery component 60 delivers the acid into the pure water, since the acid delivery component 60 continuously moves upward along the inside of the pure water, the acid delivered by the acid delivery component 60 can enter the pure water at different depths, so that the acid can be quickly and fully mixed with the pure water, thereby improving the acidification effect and acidification efficiency of the pure water.

[0018] See also Figure 1 , Figure 2 as well as Figure 4In one embodiment, the lifting assembly 20 includes a lifting plate 201, and a cavity (not shown in the figure) is opened inside the lifting plate 201. The pumping assembly 40 includes a connecting pipe 401, a piston sleeve 402 and an annular piston block 403. The piston sleeve 402 is fixedly installed on the top of the inner side of the processing box 10. The upper end of the connecting pipe 401 extends to the inside of the piston sleeve 402, and the lower end is fixedly connected to the upper part of the lifting plate 201 and communicates with the cavity. The annular piston block 403 is fixedly arranged on the outer wall of the connecting pipe 401 located inside the piston sleeve 402. An acid liquid inlet pipe 102 is arranged on the top of the processing box 10, one end of the acid liquid inlet pipe 102 is connected to the external acid liquid box, and the other end is communicated with the piston sleeve 402. A one-way valve (not shown in the figure) is arranged inside the connecting pipe 401 and inside the acid liquid inlet pipe 102. The acid delivery assembly 60 is arranged at the bottom of the lifting plate 201 and communicates with the cavity.

[0019] Before the pure water to be acidified is introduced into the treatment box 10, the driving assembly 50 drives the lifting plate 201 to move downward along the inside of the treatment box 10, and the lifting plate 201 drives the connecting tube 401 to move the connecting tube 401 to the outside of the piston sleeve 402, thereby driving the annular piston block 403 to move downward along the inside of the piston sleeve 402. At this time, the annular piston block 403 draws the acid in the external acid tank from the acid inlet pipe 102 into the piston sleeve 402. When the lifting plate 201 moves to the lower position inside the treatment box 10, the pure water to be acidified is introduced from the water inlet 101. To the inside of the treatment box 10, and then the driving component 50 drives the lifting plate 201 to move up along the inside of the treatment box 10, and the lifting plate 201 drives the connecting tube 401 to make the connecting tube 401 move toward the inside of the piston sleeve 402, and then drives the annular piston block 403 to move up along the inside of the piston sleeve 402, and the annular piston block 403 presses the acid liquid extracted into the inside of the piston sleeve 402 to the cavity inside the lifting plate 201 through the connecting tube 401, and then enters the inside of the acid delivery component 60 from the cavity, and finally is transported to the pure water through the acid delivery component 60 to acidify the pure water.

[0020] See also Figure 5 In one embodiment, the acid delivery component 60 includes a flexible acid delivery tube belt 601 and a coil spring 602, one end of the flexible acid delivery tube belt 601 is connected to the bottom of the lifting plate 201 and communicates with the cavity, and the coil spring 602 is arranged on the outer wall of the flexible acid delivery tube belt 601, and is used to drive the flexible acid delivery tube belt 601 to be in a curled state.

[0021] When the lifting plate 201 moves upward along the inside of the processing box 10 so that the annular piston block 403 presses the acid liquid inside the piston sleeve 402 into the cavity through the connecting pipe 401, the acid liquid enters the flexible acid delivery pipe belt 601 through the cavity, and is then transported into the pure water by the flexible acid delivery pipe belt 601 to achieve acidification treatment of the pure water. When the acid liquid enters the flexible acid delivery pipe belt 601, the curled flexible acid delivery pipe belt 601 can be driven to rotate and straighten. During the rotation and straightening process of the flexible acid delivery pipe belt 601, the flexible acid delivery pipe belt 601 can transport the acid liquid to different positions inside the pure water, thereby increasing the transportation range of the acid liquid, achieving uniform mixing of the acid liquid and the pure water, and improving the acidification effect of the pure water.

[0022] See also Figure 1 In one embodiment, the lifting plate 201 is the same size as the inner cavity of the processing box 10 , and a plurality of water filtering holes 202 are provided on the lifting plate 201 .

[0023] When the lifting plate 201 moves upward along the inside of the processing box 10, the pure water located at the upper position of the lifting plate 201 can pass through the filter water hole 202 from top to bottom, and the impurities in the pure water are intercepted at the upper part of the lifting plate 201, thereby achieving the filtration of impurities in the pure water.

[0024] See also Figure 1 In one embodiment, a cleaning assembly 30 is further provided on the upper portion of the lifting plate 201 . When the lifting plate 201 moves up along the inside of the processing box 10 and moves out of the pure water, the cleaning assembly 30 is used to clean the impurities filtered out through the water filter holes 202 .

[0025] See also Figure 1 as well as Figure 3 In one embodiment, an impurity storage groove 203 is provided at the upper edge of the lifting plate 201, and the cleaning assembly 30 includes a scraper 301, an L-shaped sealing plate 302, a gear 303, a screw rod 304, an elastic member 305 and a rack 306. The L-shaped sealing plate 302 is arranged above the impurity storage groove 203 to seal the impurity storage groove 203. The bottom of the scraper 301 is in contact with the upper surface of the lifting plate 201, and one end of the screw rod 304 is rotatably connected to the lifting plate 201. It is connected to a support plate 307, the other end of which passes through the scraper 301 and the L-shaped sealing plate 302 in sequence and is fixedly connected to the gear 303, the screw rod 304 is threadedly matched with the scraper 301, the support plate 307 is fixedly arranged on the upper part of the lifting plate 201, the rack 306 is fixedly installed on the inner wall of the processing box 10 and can engage with the gear 303, one end of the elastic member 305 is connected to the scraper 301, and the other end is connected to the L-shaped sealing plate 302.

[0026] When the lifting plate 201 moves upward along the inside of the treatment box 10, it can drive the scraper 301, the L-shaped sealing plate 302, the screw 304 and the gear 303 to move upward synchronously. When the lifting plate 201 is removed from the pure water, the gear 303 moves to one side of the rack 306 and enters into a meshing state with the rack 306. Then the rack 306 drives the gear 303 and the screw 304 to rotate. When the screw 304 rotates, it drives the scraper 301 to fit in with the screw thread of the scraper 301. The scraper 301 slides on the upper surface of the lifting plate 201. When sliding, it pushes away the impurities intercepted on the upper part of the water filter hole 202 on the one hand, and on the other hand, it pushes the L-shaped sealing plate 302 through the elastic member 305 so that the L-shaped sealing plate 302 is removed from the upper part of the impurity storage groove 203. When the L-shaped sealing plate 302 is removed from the upper part of the impurity storage groove 203, the scraper 301 pushes the impurities pushed away from the upper part of the water filter hole 202 to the inside of the impurity storage groove 203, thereby collecting and storing the impurities.

[0027] In one embodiment, the elastic member 305 may be a spring or a metal spring, which is not limited here.

[0028] In one embodiment, a drain pipe (not shown in the figure) is disposed at the lower portion of the side wall of the processing box 10, and a drain valve (not shown in the figure) is disposed in the drain pipe.

[0029] When the pure water in the processing box 10 is completely acidified, the drain valve in the drain pipe can be opened to discharge the pure water after acidification through the drain pipe.

[0030] In one embodiment, the driving assembly 50 may be a linear motor or a hydraulic cylinder, which is not limited here.

[0031] In the embodiment of the present invention, initially, the lifting assembly 20 is located at the lower inner part of the treatment box 10. When the pure water needs to be acidified, the pure water can be introduced into the treatment box 10 from the water inlet 101, and then the driving assembly 50 drives the lifting assembly 20 to move upward along the inside of the treatment box 10. When the lifting assembly 20 moves upward, it drives the acid delivery assembly 60 to move upward synchronously. At the same time, the pumping assembly 40 is used to pump the acid in the external acid tank into the acid delivery assembly 60, and then the acid delivery assembly 60 delivers it to the pure water, thereby achieving the acidification of the pure water. When the acid delivery component 60 delivers the acid liquid into the pure water, since the acid delivery component 60 continuously moves upward along the inside of the pure water, the acid liquid delivered by the acid delivery component 60 can enter the pure water at different depths, so that the acid liquid can be quickly and fully mixed with the pure water, thereby improving the acidification effect and acidification efficiency of the pure water. Compared with the prior art, when the pure water is acidified, automatic acidification of the pure water can be achieved, and the added acid liquid can be mixed into the pure water at different depths by itself, thereby improving the acidification effect and acidification efficiency of the pure water.
