Description

Technical Field

[0001] This utility model relates to the field of spray liquid supply system technology, and in particular to a vertical chemical pump liquid supply system for a spray tower. Background Technology

[0002] Currently, in spray system liquid supply systems, after adding chemicals, the mixture relies on an agitator installed inside the tank for stirring and mixing, requiring a motor-driven agitator. For example, CN222468620U discloses a chemical waste gas spray scrubbing tower, including a tower body, cover, dosing cylinder, dosing pipe, main pipe, branch pipe, water pump, suction pipe, circulating water tank, spray heads, and an automatic feeding mechanism. The liquid supply system of the spray scrubbing tower consists of components such as the dosing cylinder, dosing pipe, main pipe, branch pipe, water pump, suction pipe, and circulating water tank. The dosing cylinder and water pump are both located at the top of the circulating water tank, with a dosing pipe at the bottom of the dosing cylinder. The suction pipe is connected to the suction end of the water pump, which is located at the bottom of the pump. Both the dosing pipe and suction pipe pass through the circulating water tank. The discharge end of the water pump is connected to the main pipe, which is located at the front end of the pump. The main pipe is connected to two branch pipes. An agitator is installed inside the circulating water tank for stirring and mixing the liquid.

[0003] The inclusion of agitators makes it difficult to further reduce the cost of the liquid supply system. During operation, a malfunction in the agitator's motor can affect the normal operation of the system. Furthermore, most water pumps are currently installed outdoors, making them susceptible to overheating under high temperatures, which can negatively impact performance and even cause the pump to shut down. Additionally, chemicals are typically stored in a chemical preparation room, and different waste gas treatments require different chemicals. Staff usually have to select the appropriate chemical based on the specific liquid supply system, which involves long distances and occasional errors in chemical selection.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology and its main purpose is to provide a vertical chemical pump liquid supply system for a spray tower. The system uses a conical channel combined with a water inlet pipe and a guide plate to flush the water downwards and to the right along the guide plate and into the right end area of ​​the liquid tank. By utilizing the hydraulic potential energy and gravity flushing, the system eliminates the need for a stirrer or manual stirring, thus achieving automatic mixing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vertical chemical pump supply system for a spray tower includes a chemical tank, a vertical chemical pump installed on top of the chemical tank, and an outlet pipe connected to the vertical chemical pump.

[0008] The top wall of the chemical tank is provided with dosing tanks and pump mounting slots arranged at left and right intervals. The vertical chemical pump is installed in the pump mounting slot. Inside the chemical tank, corresponding to the dosing tank, there is a conical channel that is wider at the top and narrower at the bottom. The lower end of the conical channel is a narrow opening extending left and right, and the upper end of the conical channel is a wide opening matching the dosing tank. The dosing tank is provided with an openable and closable cover. The upper left side wall of the chemical tank is provided with a water inlet pipe. The left end area of ​​the chemical tank is provided with a guide plate that slopes downward from left to right. The outlet end of the water inlet pipe is higher than the left end of the guide plate, and the right end of the guide plate is higher than the bottom surface of the right end area of ​​the chemical tank. The inlet impeller of the vertical chemical pump extends into the right end area of ​​the chemical tank and is lower than the right end of the guide plate.

[0009] As a preferred embodiment, the area on the left side of the medicine tank, located below the guide plate, serves as a storage cavity.

[0010] As a preferred embodiment, the water outlet of the inlet pipe is directly opposite the downward projection area of ​​the narrow opening on the guide plate, and the width of the water outlet is greater than or equal to the width of the projection area.

[0011] As a preferred embodiment, the outlet end of the water inlet pipe is connected to a transition groove, and a water outlet gap is provided at the right end of the transition groove. The water outlet gap extends forward and backward, and is positioned directly opposite the left end of the projection area. The front-to-back width of the water outlet gap is greater than or equal to the width of the projection area.

[0012] As a preferred embodiment, the inclination angle of the guide plate is 30° to 45°.

[0013] As a preferred embodiment, the top cover of the motor of the vertical chemical pump is secured to the main body of the motor by bolts on the periphery, and the top of the top cover of the motor is provided with several heat dissipation holes; a protective heat insulation umbrella is installed on the top of the vertical chemical pump.

[0014] As a preferred embodiment, the protective heat insulation umbrella includes three uprights and an umbrella body supported and connected to the upper ends of the three uprights. The lower ends of the three uprights are pre-drilled with connection holes, which are used to install the umbrella onto the existing bolts on the periphery of the motor top cover.

[0015] As a preferred embodiment, the liquid outlet pipe extends upward and has at least two liquid outlets spaced at least vertically along its length. Furthermore, a liquid outlet switch valve is provided on the liquid outlet pipe between adjacent liquid outlets.

[0016] As a preferred embodiment, the water inlet pipe is equipped with a water inlet switch valve.

[0017] As a preferred embodiment, a liquid level sensor is installed in the right-hand area of ​​the liquid tank; the liquid level sensor, the vertical chemical pump, the inlet valve, and the outlet valve are respectively connected to the control system, which is either a self-contained control system of the vertical chemical pump supply system of the spray tower or the main control system of the spray tower, and the liquid level sensor, the vertical chemical pump, the inlet valve, and the outlet valve are connected to the main control system via control wiring harnesses.

[0018] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, it mainly uses a specially designed conical channel with a larger top and a smaller bottom in the dosing tank to achieve wide-mouth drug inlet and narrow-mouth concentrated drug drop onto the guide plate, reducing the loss of drug powder / liquid. Combined with the water inlet pipe and the guide plate, the water inlet flows diagonally downward along the guide plate and falls into the right end area of ​​the drug tank. By utilizing the water potential energy and gravity flushing, the stirrer or manual stirring operation is eliminated, and automatic mixing is achieved.

[0019] Secondly, the area on the left side of the medicine tank, located below the guide plate, serves as a storage cavity to facilitate the placement of medicines, ensuring dedicated use and preventing accidental removal of medicines.

[0020] Furthermore, protective heat insulation umbrellas are added to the original bolt locations around the top cover of the vertical chemical pump motor. With a simple structure and low cost, reliable protection is achieved for the vertical chemical pump, providing roof insulation and dust prevention. This improves upon the traditional technology where water pumps are placed outdoors, which can easily overheat and affect pump performance when exposed to high temperatures, and in severe cases, even cause the pump to overheat and shut down.

Detailed Implementation

[0029] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of an embodiment of the present invention.

[0030] In the description of this utility model, it should be noted that the terms "upper", "lower", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] A vertical chemical pump supply system for a spray tower includes a chemical tank 10, a vertical chemical pump 20 installed on top of the chemical tank 10, and an outlet pipe 30 connected to the vertical chemical pump 20. The chemical tank 10 is typically located beside the spray tower 60.

[0032] The top wall of the liquid tank 10 is provided with dosing troughs 11 and pump mounting slots 12 arranged at left and right intervals. The vertical chemical pump 20 is installed in the pump mounting slot 12. Specifically, the vertical chemical pump 20 is installed above the right end area inside the liquid tank 10. The vertical chemical pump 20 is an existing pump that can be purchased on the market, and typically includes a motor, a mounting base, a face cover, a pump housing, a water outlet pipe, a water outlet impeller, a lower end cover, etc. Its detailed structure will not be described in detail. After the vertical chemical pump 20 is installed, it can be seen that the motor of the vertical chemical pump 20 is located at the top of the liquid tank 10, and the liquid outlet pipe 30 is connected to the top of the liquid tank 10.

[0033] Inside the medicine tank 10, corresponding to the lower part of the dosing tank 11, there is a conical channel 13 that is wider at the top and narrower at the bottom. The lower end of the conical channel 13 is a narrow opening 131 extending left and right, and the upper end of the conical channel 13 is a wide opening 132 that matches the dosing tank 11. The dosing tank 11 is provided with an openable and closable cover 14, which has a handle for easy gripping and opening / closing. When the medicine is added from top to bottom, the wide opening 132 at the top facilitates the addition of medicine and avoids splashing, while the narrow opening 131 at the bottom concentrates the flow of medicine.

[0034] A water inlet pipe 40 is provided on the upper left side wall of the medicine tank 10. The water inlet pipe 40 is directed to add water into the medicine tank 10 to dilute the medicine. A guide plate 15 is provided in the left-hand area of ​​the medicine tank 10, which is inclined downward from left to right. The inclination angle of the guide plate 15 is 30° to 45°. An angle that is too large or too small is not conducive to achieving both flushing and mixing effects. The outlet end of the water inlet pipe 40 is higher than the left end of the guide plate 15, that is, it is located above the left end of the guide plate 15. The water outlet of the water inlet pipe 40 is directly opposite the downward projection area of ​​the narrow opening 131 on the guide plate 15, and the width of the water outlet is greater than or equal to the width of the projection area, so that the water flow covers the projection area. The medicine falls onto the guide plate 15, and the water falls to the left end of the guide plate 15 and flows diagonally downward along the guide plate 15 from left to right, flushing the medicine into the right end area of ​​the medicine tank 10. During flushing, the water and medicine are automatically mixed and further diluted in the right end area of ​​the medicine tank 10.

[0035] The outlet end of the water inlet pipe 40 is connected to a transition groove 41. A water outlet gap 411 is provided at the right end of the transition groove 41, extending forward and backward. The water outlet gap 411 is positioned directly opposite the left end of the projection area, and its width is greater than or equal to the width of the projection area. Water falls from the water outlet gap 411 down to the left end of the guide plate 15. The transition groove 41 allows for effective control of the water outlet width, and the selection of the water inlet pipe 40 is not limited by the water outlet. When the water in the transition groove 41 fills to the water outlet gap 411, it will naturally fall from there. The right end of the guide plate 15 is higher than the bottom surface of the right-end region 16 inside the liquid tank. The inlet impeller of the vertical chemical pump 20 extends into the right-end region inside the liquid tank 10 and is lower than the right end of the guide plate 15, maintaining a vertical distance from the bottom surface of the right-end region 16 inside the liquid tank. Thus, by specially designing a conical channel 13 with a wider top and narrower bottom within the dosing tank 11, the wide opening 132 allows for drug entry, while the narrow opening 131 concentrates the drug onto the guide plate 15, reducing powder / liquid loss. Combined with the water inlet of the inlet pipe 40 and the guide plate 15, the water flows diagonally downwards and to the right along the guide plate 15, falling into the right-end region inside the liquid tank 10. Utilizing hydraulic potential energy and gravity, automatic mixing is achieved without the need for a stirrer or manual stirring. This method can at least meet the general mixing requirements of reagents, achieving automatic mixing without stirring.

[0036] Furthermore, an inclined frame 18 can be optionally placed in the right-end region 16 of the medicine tank. The inclined surface of the inclined frame 18 receives the mixed liquid falling from the right end of the guide plate 15, and then guides it through the inclined surface of the inclined frame 18 before falling into the right-end region 16 of the medicine tank. In this way, multiple drops and inclined surface guidance are formed to improve the mixing effect.

[0037] The area on the left side of the medicine tank 10, located below the guide ramp 15, serves as a storage cavity 17, facilitating the placement of medicines for specific purposes and preventing accidental removal. A door can also be provided on the side of the medicine tank 10 corresponding to the location of the storage cavity 17 for easy opening and retrieval of medicines. Of course, for some simplified medicine tank 10 structures, the storage cavity 17 may lack a side panel, essentially remaining empty below the guide ramp 15. Considering the overall aesthetics of the medicine tank 10, it is generally a complete cuboid shape, with the guide ramp 15 and storage cavity 17 concealed within. This concealed storage cavity 17 design improves space utilization and functional integration. Compared to the traditional single-function medicine tank 10, this embodiment achieves integrated medicine storage, mixing, and pumping, resulting in a compact structure and strong practicality.

[0038] In actual dosing, manual dosing can be used. Take the medicine out of the storage chamber 17, pour it into the dosing tank, add the corresponding amount of water, and then place the dosing tank next to the medicine tank 10 (the dosing tank is placed on the dosing rack, with its bottom slightly higher than the medicine tank 10). Open the water inlet valve of the water inlet pipe 40 to let water into the medicine tank 10, and then open the switch of the dosing tank to continuously add medicine into the dosing trough 11 for a period of time until the medicine in the dosing tank is finished. During the entire dosing process, the water sent into the medicine tank 10 by the water inlet pipe is dynamically mixed and then falls into the right end area 16 of the medicine tank.

[0039] To protect the vertical chemical pump 20 from sun and dust, the motor top cover 21 of the vertical chemical pump 20 is secured to the motor body shell 22 by bolts 23 on its periphery. The top of the motor top cover 21 has several pre-set heat dissipation holes 211. A protective heat insulation umbrella 50 is installed on the top of the vertical chemical pump 20. Specifically, the protective heat insulation umbrella 50 has a simple structure and low cost. It includes three uprights 51 and an umbrella body 52 supported and connected to the upper ends of the three uprights 51. The lower ends of the three uprights 51 have pre-set connection holes 511, which are used to install the pump onto the existing bolts 23 on the periphery of the motor top cover 21. During operation, the nut 24 is removed, the connection hole 511 is fitted onto the bolt 23, and then the nut 24 is tightened. Thus, the protective heat insulation umbrella 50 covers the top of the vertical chemical pump 20 and extends beyond the outer perimeter of the vertical chemical pump 20 by a certain width, ensuring a reliable protective effect on the vertical chemical pump 20, mainly for heat insulation and dust prevention. In prolonged hot weather, the exterior of the vertical chemical pump 20 is exposed to the sun for a long time, resulting in high temperatures, which is not conducive to the effective heat dissipation of the vertical chemical pump 20 when it is working.

[0040] Typically, the outlet pipe 30 extends upwards, with at least two outlets spaced vertically along its length. An outlet valve is installed on the outlet pipe 30 between adjacent outlets. This allows for the dispensing of liquid from one or more outlets as needed, and different outlets are used to match the spraying requirements at different heights of the spray tower. Typically, an inlet valve is installed on the inlet pipe 40.

[0041] Furthermore, in other embodiments, a liquid level sensor is also provided in the right-hand region of the liquid tank 10; the liquid level sensor, the vertical chemical pump 20, the water inlet switch valve, and the liquid outlet switch valve are respectively connected to the control system, which is a self-contained control system of the vertical chemical pump 20 liquid supply system of the spray tower, or the control system is the main control system of the spray tower, and the liquid level sensor, the vertical chemical pump 20, the water inlet switch valve, and the liquid outlet switch valve are connected to the main control system via control wiring harness.

[0042] The key design feature of this invention lies in its specially designed conical channel 13, wider at the top and narrower at the bottom, within the dosing tank 11. This allows for wide-mouth drug entry and narrow-mouth concentrated drug delivery onto the guide plate 15, reducing powder / liquid loss. Combined with the water inlet pipe 40 and the guide plate 15, the water flows diagonally downwards and to the right along the guide plate 15, falling into the right-hand area of ​​the liquid tank 10. Utilizing hydraulic potential energy and gravity, this automatic mixing eliminates the need for a stirrer or manual stirring. Secondly, the area on the left side of the liquid tank, located below the guide plate, serves as a storage cavity, facilitating dedicated placement of the medication and preventing accidental removal. Furthermore, protective heat insulation umbrellas are added to the original bolt locations around the top cover of the vertical chemical pump motor. With a simple structure and low cost, reliable protection is achieved for the vertical chemical pump, providing roof insulation and dust prevention. This improves upon the traditional technology where water pumps are placed outdoors, which can easily overheat and affect pump performance when exposed to high temperatures, and in severe cases, even cause the pump to overheat and shut down.

[0043] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
