Description

Technical Field

[0001] This utility model relates to the field of purified water sampling technology, specifically to a purified water storage tank that facilitates sampling. Background Technology

[0002] In the pharmaceutical process, purified water is usually required to prepare the drug solution. Ordinary tap water is processed into qualified purified water through a purified water production system and stored in a purified water storage tank. Then, the purified water is transported to various water use points through downstream pipelines.

[0003] Currently, according to the purified water testing standards, it is necessary to regularly sample and test the purified water in the purified water storage tank. Existing storage tanks are generally equipped with sampling tubes with open valves. Before sampling, the open valves are opened to drain water for 3 minutes to remove stagnant water accumulated in the pipes. Since the purified water in the storage tank needs to be tested multiple times, the stagnant water accumulated in the pipes needs to be drained before each test. In the long run, this can easily lead to waste of purified water, making it inconvenient to sample purified water from existing storage tanks.

[0004] Therefore, it is necessary to provide a new purified water storage tank that is easy to sample to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a purified water storage tank that makes it easier to sample purified water.

[0006] The present invention provides a purified water storage tank for easy sampling, comprising a tank body, an inlet pipe connected to the top of the tank body, an outlet pipe connected to one side of the tank body, and a sampling mechanism provided on the side of the tank body away from the outlet pipe, the sampling mechanism facilitating the sampling of purified water inside the tank body.

[0007] The sampling mechanism includes a sampling box fixed to one side of the tank body. A sampling tube is connected to the bottom of the sampling box. A first water intake hole is opened on one side of the tank body, and a second water intake hole is opened on one side of the sampling box. The first water intake hole and the second water intake hole are connected. A motor is fixed to one side of the top of the sampling box. A drive shaft is fixedly connected to the output end of the motor. An installation box is fixedly connected to the inner wall of one side of the sampling box. The bottom end of the drive shaft passes through the sampling box and extends into the installation box. A first gear is fixedly connected to the bottom end of the drive shaft extending into the installation box. A second gear is meshed inside the installation box and outside the first gear. A lead screw is fixed to the second gear. A threaded sleeve is fixed to the outside of the installation box extending from the lead screw. A sealing plate is fixedly connected to the end of the threaded sleeve away from the installation box.

[0008] In order to achieve a better sealing effect between the sealing plate and the side wall of the sampling box, as a purified water storage tank that facilitates sampling, the sealing plate is preferably fixedly connected to a sealing gasket at the end away from the wire sleeve, and the other end of the sealing gasket overlaps with the inner wall of one side of the sampling box.

[0009] In order to achieve the effect of normal rotation of the bottom end of the drive shaft inside the mounting box, as a purified water storage tank for easy sampling provided by this utility model, preferably, a bearing seat is fixed on the bottom wall of the mounting box and located at the end of the drive shaft, and the drive shaft is rotatably connected inside the bearing seat.

[0010] In order to guide the movement of the sealing plate, as a purified water storage tank for easy sampling provided by this utility model, preferably, two vertical plates are fixed on the outside of the mounting box in a symmetrical arrangement, and two guide rods are fixed on one side of the vertical plates. One end of the guide rod passes through the sealing plate and the sealing gasket in sequence and is fixedly connected to the inner wall of one side of the sampling box. The sealing plate is slidably connected to the guide rod.

[0011] In order to prevent purified water from accumulating inside the sampling box, as a purified water storage tank that facilitates sampling, the sampling box preferably has two inclined plates that are symmetrically distributed on the left and right sides fixed to the bottom wall, and the top of the inclined plates is fixedly connected to the inner side wall of the sampling box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This convenient purified water storage tank replaces the existing purified water sampling method by adopting a sampling mechanism. It eliminates the need to drain stagnant water from the pipeline before sampling, thus avoiding waste of purified water. It also solves the problem that the existing storage tank is inconvenient for purified water sampling because the purified water in the storage tank needs to be tested multiple times, and stagnant water needs to be drained from the pipeline before each test, which can easily lead to waste of purified water in the long run.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in Figure 1 A schematic diagram of the structure of the purified water storage tank that facilitates sampling, provided by this utility model; Figure 2 This is a three-dimensional view of the sampling box structure of this utility model; Figure 3 This is a schematic diagram of the internal structure of the sampling box of this utility model; Figure 4This is a partial structural diagram of the sampling mechanism of this utility model. The purified water storage tank, designed for easy sampling, includes a tank body 1. An inlet pipe 2 is connected to the top of the tank body 1, and an outlet pipe 3 is connected to one side of the tank body 1. A sampling mechanism is located on the side of the tank body 1 away from the outlet pipe 3, facilitating sampling of the purified water inside the tank body 1. The sampling mechanism includes a sampling box 101 fixed to one side of the tank body 1. A sampling tube 102 is connected to the bottom of the sampling box 101, and a valve is provided on the outside of the sampling tube 102. A first water intake hole 103 is opened on one side of the tank body 1, and a second water intake hole 104 is opened on one side of the sampling box 101. The first water intake hole 103 and the second water intake hole 104 are connected. A motor 105 is fixed to one side of the top of the sampling box 101. The output end of the motor 105 is fixedly connected to a drive shaft 106. A mounting box 107 is bolted to the inner wall of the right side of the sampling box 101. The bottom end of the drive shaft 106 passes through the sampling box 101 and extends into the mounting box 107. Furthermore, a bearing groove is provided on the top right side of the sampling box 101, and a sealed bearing is inserted into the bearing groove with an interference fit. The drive shaft 106 is inserted into the inner ring of the sealed bearing with an interference fit. The drive shaft 106 extends through to the bottom end of the mounting box 107 and is fixedly connected to a first gear 108. A bearing groove is provided on the top of the mounting box 107, and a sealed bearing is inserted into the bearing groove with an interference fit. The drive shaft 106 is inserted into the inner ring of the sealed bearing with an interference fit. A second gear 109 is meshed inside the mounting box 107 and outside the first gear 108. The center position of the second gear 109 is keyed to a lead screw 110. The lead screw 110 extends out of the mounting box 107 and is fixedly connected to a threaded sleeve 111. A bearing groove is provided on the left side of the mounting box 107, and a sealed bearing is inserted into the bearing groove with an interference fit. The right end of the lead screw 110 is inserted into the inner ring of the sealed bearing with an interference fit. The end of the threaded sleeve 111 away from the mounting box 107 is fixedly connected to a sealing plate 112.

[0021] Food-grade rubber sleeves are fitted onto the threaded tube 111 and the threaded rod 110, and the two ends of the rubber sleeves are respectively welded to the sealing plate 112 and the vertical plate 115;

[0022] With the above technical solution, when it is necessary to sample the purified water in tank 1, the sampling container is placed at the bottom of the sampling tube 102, and the valve on the outside of the sampling tube 102 is opened. The motor 105 drives the transmission shaft 106 to rotate with the first gear 108 in the mounting box 107. The first gear 108 drives the second gear 109 to rotate with the lead screw 110. The screw of the lead screw 110 drives the lead screw 110 to move the lead screw 110 to the right. The lead screw 110 drives the sealing plate 112 to move synchronously, releasing the sealing plate 112 from the second water intake hole 104. This allows the purified water in tank 1 to enter the sampling box 101 through the first water intake hole 103 and the second water intake hole 104, and then enter the sampling container through the sampling tube 102. When the tank is nearly full, the motor 105 drives the transmission shaft 106 to rotate in the opposite direction to the first gear 108. The first gear 108 drives the second gear 109 to rotate in the opposite direction to the lead screw 110. The rotation of the lead screw 110 drives the threaded sleeve 111 to move to the left, which in turn drives the sealing plate 112 to move to the left. This causes the sealing plate 112 to block the second water intake hole 104, stopping the purified water from entering the sampling box 101. After all the purified water in the sampling box 101 has entered the sampling container, the valve is closed. This completes the sampling of the purified water in the tank 1, replacing the existing purified water sampling method. This eliminates the need to drain stagnant water from the pipeline before sampling the purified water in the tank 1, avoiding waste of purified water and making purified water sampling more convenient.

[0023] Reference Figure 2 , Figure 3 and Figure 4 A sealing gasket 113 is fixedly connected to one end of the sealing plate 112 away from the wire sleeve 111. The other end of the sealing gasket 113 overlaps with the inner wall of the sampling box 101. By fixing the sealing gasket 113 to one side of the sealing plate 112, the sealing performance when the sealing plate 112 contacts the inner wall of the sampling box 101 is effectively improved to prevent the purified water from leaking.

[0024] Reference Figure 3 A bearing seat 114 is fixed to the bottom wall of the mounting box 107 and at the end of the drive shaft 106. The lower end of the drive shaft 106 is interference-fitted into the inner ring of the bearing in the bearing seat 114. When the drive shaft 106 rotates, its bottom end rotates in the bearing seat 114, making the drive shaft 106 drive the first gear 108 to rotate more stably.

[0025] Reference Figure 2 , Figure 3 and Figure 4Two vertical plates 115 are fixed to the outside of the mounting box 107 in a symmetrical arrangement. Two guide rods 116 are fixed to one side of the vertical plates 115. One end of the guide rod 116 passes through the sealing plate 112 and the sealing gasket 113 in sequence and is fixedly connected to the inner wall of one side of the sampling box 101. The sealing plate 112 is slidably connected to the guide rod 116. When the sealing plate 112 moves left and right in the sampling box 101, the guide rod 116 limits and guides the movement of the sealing plate 112, making the sealing plate 112 more stable during the movement.

[0026] Reference Figure 2 and Figure 3 Two inclined plates 117 are fixedly arranged symmetrically on the bottom wall of the sampling box 101. The top of the inclined plates 117 is fixedly connected to the inner side wall of the sampling box 101. The inclined plates 117 guide the flow of purified water, so that the purified water flows downward into the sampling tube 102, and avoids the purified water from accumulating inside the sampling box 101.

[0027] The implementation principle of the purified water storage tank for easy sampling in this embodiment of the utility model is as follows: By adopting a sampling mechanism, when it is necessary to sample the purified water in the tank 1, the sampling container is placed at the bottom of the sampling tube 102, and the valve on the outside of the sampling tube 102 is opened. The motor 105 drives the transmission shaft 106 to rotate with the first gear 108 in the mounting box 107. The first gear 108 drives the second gear 109 to rotate with the lead screw 110. The screw connection of the lead screw 110's threaded sleeve 111 causes the lead screw 110 to drive the threaded sleeve 111 to move to the right. The threaded sleeve 111 drives the sealing plate 112 to move synchronously, releasing the sealing plate 112 from the second water intake hole 104. This allows the purified water in the tank 1 to enter the sampling box 101 through the first water intake hole 103 and the second water intake hole 104, and then enter the sampling tube 102. When the sample container is nearly full, the motor 105 drives the transmission shaft 106 and the first gear 108 to rotate in the opposite direction. The first gear 108 drives the second gear 109 and the lead screw 110 to rotate in the opposite direction. The rotation of the lead screw 110 drives the threaded sleeve 111 to move to the left, causing the threaded sleeve 111 to drive the sealing plate 112 to move to the left. This causes the sealing plate 112 to block the second water intake hole 104, stopping the purified water from entering the sampling box 101. After all the purified water in the sampling box 101 has entered the sample container, the valve is closed. This completes the sampling of the purified water in the tank 1, replacing the existing purified water sampling method. This eliminates the need to drain stagnant water from the pipeline before sampling the purified water in the tank 1, avoiding waste of purified water and making purified water sampling more convenient.
