Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a disinfectant dosing auxiliary device. Background Technology
[0002] During the operation of water treatment disinfection processes, it is necessary to add chemicals to the dissolving tank. Currently, when adding chemicals, operators add chlorine dioxide effervescent tablets to a covered dissolving tank filled with water as required. The dissolved disinfectant is then delivered to the dosing point via a water jet injector or metering pump. Currently, when adding chemicals, the weighed chemicals are added to the dissolving tank using a small shovel. When the effervescent tablets dissolve, a large amount of volatile chlorine dioxide gas overflows from the dosing port. Chlorine dioxide gas is easily soluble in water, is an effective disinfectant component, has an irritating odor, and is corrosive. The overflow of chlorine dioxide gas not only causes the loss of the effective disinfectant component but also causes environmental pollution. Utility Model Content
[0003] The purpose of this utility model is to provide a disinfectant dosing auxiliary device. With the isolation valve closed, the disinfectant is first added to the upper cylinder section, the sealing cap is closed, and then the isolation valve is opened, so that the disinfectant falls into the dissolving tank, thereby preventing chlorine dioxide gas from overflowing.
[0004] To achieve the above objectives, this utility model provides a disinfectant dosing auxiliary device, including a feeding cylinder, a shut-off valve, and a sealing cap. The feeding cylinder includes an upper cylinder section and a lower cylinder section, which are respectively installed at the upper and lower ends of the shut-off valve. The lower end of the lower cylinder section is provided with an internal thread, and the upper end of the upper cylinder section is detachably equipped with a sealing cap.
[0005] The isolation valve adopts a butterfly valve structure. The lower end of the upper cylinder section is fixedly connected to a first flange, and the upper end of the lower cylinder section is fixedly connected to a second flange. The isolation valve is located between the first flange and the second flange, and the first flange, the isolation valve and the second flange are connected and fixed by bolts.
[0006] A feeding hopper is fixedly installed at the upper end of the upper cylinder section. A metering hopper is also installed in the upper cylinder section. The metering hopper is suspended below the feeding hopper by at least three springs. A discharge port is provided on one side of the lower end of the metering hopper. The upper end of the baffle is hinged to the metering hopper by a hinge. An extension section is provided at the lower end of the baffle, which extends downwards to one end of the metering hopper. Elastic elements are installed on both sides of the baffle and are connected to the metering hopper. When the isolation valve is opened, the valve disc of the isolation valve pushes against the extension section to open the discharge port. The upper cylinder section is provided with a mark for observing the height position of the metering hopper.
[0007] An extension cylinder is also fixedly connected to the lower end of the feeding hopper.
[0008] The upper cylinder section is transparent, or a transparent observation window is provided on the upper cylinder section, and the marking is set on the transparent observation window.
[0009] An indicator plate is installed on the outer wall of the measuring hopper.
[0010] The lower side of the feeding hopper is provided with multiple first earrings, and the metering hopper is provided with second earrings at the positions corresponding to the first earrings. The two ends of the spring are hooked onto the corresponding first earrings and second earrings, respectively.
[0011] The baffle is equipped with first fixing members on both sides, and second fixing members are installed at both ends of the measuring hopper. The elastic member is installed on the first fixing members and the second fixing members.
[0012] The width of the extension is less than the width of the baffle.
[0013] The sealing cap is screwed onto the upper cylinder section via a threaded connection.
[0014] Compared with the prior art, this utility model has the following technical effects:
[0015] 1. With the isolation valve closed, the agent is first added to the upper cylinder section, the sealing cap is closed, and then the isolation valve is opened. The agent then falls into the dissolving tank, thus preventing chlorine dioxide gas from overflowing.
[0016] 2. The feeding hopper of this utility model has a conical structure that is wider at the top and narrower at the bottom. When adding chemicals, the chemicals are positioned in the middle of the feeding hopper, maintaining the balance of the metering hopper and providing an installation position for suspending the metering hopper. The metering hopper is suspended below the feeding hopper by a spring balance, forming a structure similar to a spring scale. Combined with the markings on the upper cylinder section, the weighing can be performed through the metering hopper, eliminating the need for a pallet scale when adding chemicals. The elastic force of the elastic element can close the discharge port with the baffle, and it also keeps the discharge port closed during feeding. When the isolation valve is opened, the valve disc of the isolation valve pushes against the extension section, thereby opening the discharge port, allowing the chemicals to fall from the discharge port. At this time, the isolation valve is open, and the chemicals fall directly into the dissolving tank. Attached Figure Description

[0032] Spring 260. Detailed Implementation
[0033] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.
[0034] Example 1:
[0035] See Figure 1-7A disinfectant dosing auxiliary device 200 includes a feeding cylinder 210, an isolation valve 220, and a sealing cap 230. The feeding cylinder 210 includes an upper cylinder section 211 and a lower cylinder section 212, which are respectively installed at the upper and lower ends of the isolation valve 220. The lower end of the lower cylinder section 212 is provided with an internal thread, and the upper end of the upper cylinder section 211 is detachably installed with a sealing cap 230.
[0036] With the isolation valve 220 closed, the agent is first added to the upper cylinder section 211, the sealing cap 230 is closed, and then the isolation valve 220 is opened. The agent then falls into the dissolving tank 100, thereby preventing chlorine dioxide gas from overflowing.
[0037] In this embodiment, the isolation valve 220 adopts a butterfly valve structure. The lower end of the upper cylinder section 211 is fixedly connected to the first flange 214, and the upper end of the lower cylinder section 212 is fixedly connected to the second flange 215. The isolation valve 220 is located between the first flange 214 and the second flange 215, and the first flange 214, the isolation valve 220 and the second flange 215 are connected and fixed by bolts 216.
[0038] Specifically, the sealing cap 230 is screwed onto the upper cylinder section 211 via a threaded connection.
[0039] See Figure 1 The lower end of the lower cylinder section 212 is provided with an internal thread, so that the disinfectant dosing auxiliary device 200 of this application can be screwed onto the mouth 101 of the dissolving tank 100.
[0040] In use, first close the isolation valve 220 using handle 221, open the sealing cover 230, add the agent into the upper cylinder section 211, close the sealing cover 230, then open the isolation valve 220 again, and the agent will fall into the dissolving tank 100. Then quickly close the isolation valve 220. Throughout the process, the dissolving tank 100 is in a closed state, which can prevent chlorine dioxide gas from overflowing.
[0041] Example 2:
[0042] Based on Example 1, see Figure 2-7A feeding hopper 240 is fixedly installed at the upper end of the upper cylinder section 211. A metering hopper 250 is also installed inside the upper cylinder section 211. The metering hopper 250 is suspended below the feeding hopper 240 by at least three springs 260. A discharge port 251 is provided on one side of the lower end of the metering hopper 250. The upper end of the baffle 252 is hinged to the metering hopper 250 by a hinge 2523. An extension section 2522 is provided at the lower end of the baffle 252, which extends downwards to one end of the metering hopper 250. Elastic elements 253 are installed on both sides of the baffle 252, and the elastic elements 253 are connected to the metering hopper 250. When the isolation valve 220 is opened, the valve disc 222 of the isolation valve 220 pushes against the extension section 2522 to open the discharge port 251. A mark 213 is provided on the upper cylinder section 211 for observing the height position of the metering hopper 250.
[0043] The feeding hopper 240 has a cone-shaped structure that is larger at the top and smaller at the bottom. When adding chemicals, the chemicals are located in the middle of the feeding hopper 240, maintaining the balance of the metering hopper 250, and also providing an installation position for suspending the metering hopper 250.
[0044] The measuring hopper 250 is suspended below the feeding hopper 240 by a spring 260, forming a structure similar to a spring scale. Combined with the mark 213 set on the upper cylinder section 211, the weighing can be carried out through the measuring hopper 250, so that a pallet scale is not needed when adding chemicals.
[0045] Specifically, the upper cylindrical section 211 is transparent, for example, the upper cylindrical section 211 is made of transparent acrylic material. Alternatively, the upper cylindrical section 211 is provided with a transparent observation window, and the mark 213 is set on the transparent observation window. For example, a longitudinal notch is opened in the upper cylindrical section 211, and a transparent plastic plate or acrylic plate is glued inside the notch, and the mark 213 is set on the plastic plate or acrylic plate.
[0046] The elastic element 253 can be a rubber band or a spring. The elastic force of the elastic element can cause the baffle 252 to close the discharge port 251, and it can also keep the discharge port 251 closed during feeding. When the isolation valve 220 is opened, the valve disc 222 of the isolation valve 220 pushes against the extension section 2522, see [reference]. Figure 4 This opens the discharge port 251, allowing the medicine to fall from the discharge port 251. At this time, the isolation valve 220 is open, and the medicine falls directly into the dissolving tank 100.
[0047] Furthermore, an extension cylinder 241 is fixedly connected to the lower end of the feeding hopper 240 to prevent the reagent from falling outside the metering hopper 250.
[0048] See Figure 6 An indicator plate 2503 is installed on the outer wall of the metering hopper 250. The indicator plate 2503 is used in conjunction with the mark 213 to facilitate observation of the height position of the feeding hopper 240.
[0049] See Figure 6 The lower side of the feeding hopper 240 is provided with multiple first earrings 2401, and the metering hopper 250 is provided with second earrings 2501 at the positions corresponding to the first earrings 2401. The two ends of the spring 260 are hooked onto the corresponding first earrings 2401 and second earrings 2501 respectively. The spring 260 is simple and convenient to install. In this embodiment, four springs 260 are installed.
[0050] See Figure 6 The baffle 252 is equipped with a first fixing member 2521 on both sides, and the measuring hopper 250 is equipped with a second fixing member 2502 at both ends. The elastic member 253 is installed on the first fixing member 2521 and the second fixing member 2502 to facilitate the installation of the elastic member 253.
[0051] Furthermore, Figure 6 In the middle, the width of the extension section 2522 is smaller than the width of the baffle 252, and the agent can pass through both sides of the extension section 2522, which facilitates the falling of the agent.
[0052] In this embodiment, see Figure 5 The measuring hopper 250 has a square cross-section. There is a gap between the four edges of the measuring hopper 250 and the inner wall of the upper cylinder section 211. When the valve disc 222 pushes against the extension section 2522, the four edges of the measuring hopper 250 will abut against the inner wall of the upper cylinder section 211 due to the certain height of the measuring hopper 250, which makes it easier for the baffle 252 to open.
[0053] The working principle of this utility model:
[0054] See Figure 2 First, close the isolation valve 220 using handle 221. Then, open the sealing cover 230 and add the reagent to the feeding hopper 240. The reagent falls through the feeding hopper 240 into the measuring hopper 250. As the amount of reagent in the measuring hopper 250 increases, the height of the measuring hopper 250 decreases. When it drops to the designated mark 213, it indicates that the weight meets the requirements. The amount of reagent can be slightly more, but not less. Then, close the sealing cover 230.
[0055] See Figure 3 , 4 Then, the isolation valve 220 is opened via handle 221. The valve disc 222 of the isolation valve 220 pushes against the extension section 2522 to open the discharge port 251. The reagent will then fall from the discharge port 251, through the isolation valve 220, and into the dissolving tank 100. After all the reagent has fallen, the isolation valve 220 is closed. During the process of the reagent falling, the valve disc 222 can be repeatedly pushed against the extension section 2522 by operating the handle 221 up and down to accelerate the falling of the reagent.
