Description

Technical Field

[0001] This utility model relates to the field of storage equipment technology, and in particular to a storage and protection device for composite phosphorus removal adsorbent. Background Technology

[0002] Composite phosphorus removal agents are materials used for phosphorus removal in urban water sources. When storing composite phosphorus removal agents, they need to be stored at a relatively low temperature and in a moisture-proof and sealed manner. Currently, there are many special devices for storing composite phosphorus removal agents in existing technologies.

[0003] In existing technologies, composite descaling agents are often stored in boxes or tanks, and some boxes or tanks are equipped with negative pressure pumps to evacuate air from the tank or container. When retrieving the agent, some boxes or tanks require opening the top cover. To improve ease of retrieval, some boxes or tanks have a discharge pipe at the bottom. The discharge pipe facilitates material removal and reduces the entry of external air when the cover is opened. For example, Chinese patent application number 202022052850X discloses a technology for storing composite descaling agents in a sealed box. It uses a stirring blade and a discharge pipe to release the material, which not only stores the descaling agent but also facilitates its later retrieval.

[0004] However, since the box or tank is sealed and some are equipped with negative pressure pumps, the material discharge speed is slow when the discharge pipe is opened. Furthermore, outside air can enter the box or tank through the discharge pipe during the material discharge process, so there is still room for improvement. Utility Model Content

[0005] The purpose of this invention is to solve the above-mentioned problems by providing a storage and protection device for composite phosphorus removal adsorbents.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a composite phosphorus removal adsorbent storage and protection device, comprising a storage tank, the storage tank being provided with a connecting pipe, and an air replenishment component, the air replenishment component comprising: A cylindrical body is connected to a connecting pipe at one end and a third pipe at the other end. A first control valve is installed between the cylindrical body and the connecting pipe, and a three-way switching valve is installed at the other end of the third pipe. The isolation plate is axially guided and installed inside the cylindrical body, with its outer circumferential surface slidingly sealing against the inner circumferential surface of the cylindrical body; The deoxidizer is placed inside the cylindrical body and located on the side of the isolation plate near the third tube; The first air supply pipe is connected to one end of the connecting pipe that connects to the cylindrical body.

[0007] Furthermore, the cylindrical body is vertically arranged, with its upper end connected to the third pipe and its lower end connected to the second pipe and the first air supply pipe.

[0008] Furthermore, a second control valve is provided at the end of the first air supply pipe away from the cylindrical body, and the other end of the second control valve is used to connect to the air source.

[0009] Furthermore, the first air supply pipe includes a horizontally extending first section, the second pipe includes a second section that is parallel to and spaced apart from the first section, the second control valve is disposed in the first section, and the three-way switching valve is disposed in the second section.

[0010] Furthermore, the three-way switching valve is a manual valve. The common end of the three-way switching valve is connected to the second pipe, one air inlet is connected to the atmosphere, and the other air inlet is used to connect to the compressed air source.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] Please refer to Figure 1-7 The technical solution of this utility model is as follows: a composite phosphorus removal adsorbent storage and protection device, including a storage tank 1, the storage tank 1 being provided with a connecting pipe 13, and also including an air replenishment component 2, the air replenishment component 2 comprising: A cylindrical body is connected to a connecting pipe 13 at one end and a third pipe 21 at the other end. A first control valve 1310 is provided between the cylindrical body and the connecting pipe 13, and a three-way switching valve 210 is provided at the other end of the third pipe 21. The isolation plate 26 is axially guided and disposed inside the cylindrical body, with its outer circumferential surface slidingly sealing against the inner circumferential surface of the cylindrical body; The deoxidizer is placed inside the cylindrical body and located on the side of the isolation plate 26 near the third tube 21; The first air supply pipe 22 is connected to one end of the cylindrical body connecting pipe 13.

[0026] Specifically, it should be noted that the reference is... Figures 1-3 The storage tank 1 in this application is consistent with the prior art. It is provided with a discharge pipe 10 at the lower end and a first end cover is detachably and fixedly connected to the upper end. The first end cover is provided with a feed port. An upper end cover 12 is detachably and fixedly connected to the feed port. A connecting pipe 13 is welded to the first end cover. A first pipe 130 is provided on the connecting pipe 13. The first pipe 130 is used to connect with a negative pressure air pump (not shown in the figure). A valve structure (not shown in the figure) is also provided at the discharge pipe 10. The above structures are all conventional means in the prior art and are not improvements of this application. Their internal structure and working method will not be described in detail. Those skilled in the art should understand.

[0027] The improvement of this application is that it also includes a gas replenishment component 2. Specifically, the gas replenishment component 2 has the following structure: a second pipe 131 is connected to the connecting pipe 13; a columnar cylinder is detachably fixed to the outer wall of the storage tank 1 using a clamp 3; both ends of the cylinder are sealed; an isolation plate 26 is provided inside the cylinder for guidance; one end is connected to the second pipe 131; a first control valve 1310 is provided on the second pipe 131; and a third pipe 21 is also connected to the second pipe 21; a three-way switching valve 210 is provided on the third pipe 21; and the other end is connected to the first gas replenishment pipe 22; the first gas replenishment pipe 22 is connected to the first... The second control valve 220 has an oxygen desiccant at one end. In use, the three-way switching valve 210 and the second control valve 220 are both connected to the second air supply pipe 23. The second air supply pipe 23 is connected to the compressed air source. It can be understood that the compressed air source in the factory is provided by a compressor and is equipped with a compressed air tank. When the compressor compresses the air, it removes and separates the water vapor in the air, thereby avoiding damage to the compressed air delivery pipeline at the downstream end. In other words, the compressed air delivered in the factory has been dehumidified and is relatively dry, which can be used to replenish the air inside the storage tank 1.

[0028] The working principle of the air replenishment component 2 is as follows: When the storage tank 1 is in the storage state, the first control valve 1310 is closed, and the three-way switching valve 210 is in the state of connecting the third pipe 21 and the atmosphere. At this time, the second control valve 220 is opened and kept open for more than 30 seconds, and compressed gas enters the cylindrical body, pushing the isolation plate 26 to move, so that compressed air is replenished in the cylindrical body. Then the second control valve 220 is closed, and the gas is stored in the cylindrical body. When the storage tank 1 discharges material, if the storage tank 1 is equipped with a negative pressure air pump, the negative pressure air pump is de-energized at this time, the second control valve 220 is kept closed, and the three-way switching valve 210 is switched to the state of connecting the third pipe 21 and the compressed air source. At this time, the compressed gas enters the other end of the cylindrical body, and then the material is discharged. The valve structure on the discharge pipe 10 is opened, and then the first control valve 1310 is opened. At this time, the compressed gas will push the isolation plate 26 to move and squeeze the gas in the cylindrical body into the storage tank 1 for air replenishment, which is conducive to the rapid discharge of material in the storage tank 1.

[0029] By introducing a deoxygenating agent, oxygen can be removed from the supplementary gas stored in the columnar cylinder for an extended period, thereby reducing the oxygen content in the supplementary gas within the columnar cylinder.

[0030] Specifically, in practical applications, the volume of the columnar cylinder is controlled according to the amount of composite phosphorus removal adsorbent used each time. The volume of the columnar cylinder is 1.2-1.3 times the amount used each time to ensure that enough composite phosphorus removal adsorbent can be discharged in a single application.

[0031] It is understandable that when a large amount of composite phosphorus removal adsorbent needs to be used or all materials in storage tank 1 need to be discharged, compressed air can be directly added to the inside of storage tank 1 by opening the second control valve 220.

[0032] Furthermore, as a specific implementation, the cylindrical body is vertically arranged, with its upper end connected to the third pipe 21 and its lower end connected to the second pipe 131 and the first air supply pipe 22. This arrangement facilitates subsequent replacement of the deoxidizer.

[0033] Furthermore, as a specific implementation, a second control valve 220 is provided at the end of the first air supply pipe 22 away from the cylindrical body, and the other end of the second control valve 220 is used to connect to the air source. Specifically, the second control valve 220 is a manual control valve.

[0034] Furthermore, as a specific implementation method, refer to Figure 4The first air supply pipe 22 includes a horizontally extending first section, and the second pipe 131 includes a second section spaced parallel to the first section. The second control valve 220 is located in the first section, and the three-way switching valve 210 is located in the second section. Specifically, the first pipe 130, the second pipe 131, the third pipe 21, and the first air supply pipe 22 are all rigid pipes. By setting the first and second sections spaced parallel to each other, the three-way switching valve 210 and the second control valve 220 can be placed close together, which facilitates control of the control valves during use. As a specific implementation, the three-way switching valve 210 is a manual three-way switching valve 210.

[0035] Furthermore, as a specific implementation, the three-way switching valve 210 is a manual valve. The common end of the three-way switching valve 210 is connected to the second pipe 131, one air inlet end is connected to the atmosphere, and the other air inlet end is used to connect to the compressed air source.

[0036] Furthermore, in a preferred embodiment, the lower end of the cylindrical body is provided with an opening, and a third cover 25 is detachably and fixedly connected to the opening, on which the deoxidizer is disposed. Specifically, the detachably and fixedly connected third cover 25 facilitates the removal of the third cover 25 for replacement of the deoxidizer.

[0037] Furthermore, as a specific implementation method, refer to Figure 7 A connecting cylinder 24 is provided at the opening, and the third cover 25 is threadedly connected to the connecting cylinder 24. A cylindrical surrounding plate 250 is coaxially provided on the end face of the third cover 25. Specifically, the connecting cylinder 24 is connected to the bottom surface of the cylindrical body by welding. The connecting cylinder 24 is provided with external threads. The third cover 25 is threadedly connected to the connecting cylinder 24. The cylindrical surrounding plate 250 is integrally provided on the end face of the third cover 25, which can form a cavity, facilitating the placement of deoxidizer within the surrounding plate 250.

[0038] Furthermore, in a preferred embodiment, a second cover 20 is detachably and fixedly connected to the upper end of the cylindrical body. The second cover 20 is provided with a guide rod 201, the axis of which is parallel to the axis of the cylindrical body. The isolation plate 26 is guided and slidably sealed with the guide rod 201. Specifically, the guide rod 201 is integrally formed with the second cover 20 by welding. By providing the guide rod 201 to guide the middle area of ​​the isolation plate 26, the smooth movement of the isolation plate 26 is facilitated.

[0039] Furthermore, as a specific implementation method, refer to Figure 7The lower end of the guide rod 201 is spaced apart from the bottom surface of the cylindrical body, and a nut 27 is threadedly connected to the lower end. Specifically, the nut 27 is threadedly connected to the lower end of the guide rod 201, and the upper surface of the nut 27 can limit the isolation plate 26, thereby achieving the effect of positioning the isolation plate 26 and preventing the isolation plate 26 from moving beyond its travel range.

[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
