Description

Technical Field

[0001] This utility model relates to the field of tanker unloading technology, and in particular to a liquid pharmaceutical tanker unloading device for sewage treatment plants. Background Technology

[0002] In the actual operation of wastewater treatment plants, the addition of liquid chemicals is a crucial step in ensuring the effectiveness of wastewater treatment. Tanker truck transportation, due to its flexibility and large capacity, has become one of the main modes of transport for liquid chemicals. Therefore, efficiently and safely unloading liquid chemicals from tankers into the storage devices of the wastewater treatment plant is an indispensable and vital step in the entire wastewater treatment process. Currently, some wastewater treatment plant liquid chemical tanker unloading devices lack structural design considerations for adapting to different tanker discharge pipe heights. Tankers from different manufacturers have varying discharge pipe heights, while the inlet pipe height of existing unloading devices is often fixed. This makes it difficult to ensure precise and stable connection between the inlet pipe's insertion tube and the tanker's discharge pipe during actual connection. Even if some devices use simple support structures to adjust the inlet pipe height, these structures mostly lack effective limiting mechanisms. During unloading, the flow of liquid chemicals generates a certain impact force, which can easily cause the inlet pipe to shake or shift, leading to the insertion tube detaching from the tanker's discharge pipe and causing liquid chemical leakage. Leaks not only waste chemicals and increase production costs, but also pollute the surrounding environment and pose a threat to the health of operators. For example, leaks of highly corrosive liquid chemicals can corrode the ground and equipment, making cleanup difficult and costly. Existing unloading devices are cumbersome in clamping tanker discharge pipes. Some devices use traditional bolt fastening methods, requiring operators to tighten each bolt individually with tools to clamp the discharge pipe. This method is not only time-consuming and labor-intensive, but also makes it difficult to ensure uniform tightening of each bolt, leading to uneven clamping and affecting the clamping effect. Furthermore, adjusting the feed pipe height to accommodate different tanker discharge pipe heights requires disassembling multiple parts, reassembling and repositioning them, a complex process that demands high operator skills. This not only increases the workload of operators but also prolongs unloading preparation time, reduces overall unloading efficiency, and fails to meet the high-efficiency production requirements of wastewater treatment plants. For example, in large-scale wastewater treatment plants, multiple truckloads of liquid chemicals need to be unloaded every day. If each unloading takes a lot of time due to the complexity of the equipment operation, it will seriously affect the normal operation of the entire wastewater treatment process. Utility Model Content

[0003] To address the aforementioned problems, this utility model proposes a liquid reagent tanker unloading device for sewage treatment plants, which more accurately solves the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model proposes a liquid reagent tanker unloading device for a wastewater treatment plant, including a pressure stabilizing tank and a tanker discharge pipe connected to the tanker. A discharge pipe and a feed section are installed at the bottom of the pressure stabilizing tank. The discharge pipe is used for discharging, and the feed section is used for feeding. The feed section includes a first feed pipe installed on the surface of the pressure stabilizing tank. A connecting hose is installed at the end of the first feed pipe, and a second feed pipe is installed at the end of the connecting hose. A support is installed at the bottom of the second feed pipe for supporting the second feed pipe, and the height of the support is adjustable. An insertion pipe is installed at the end of the second feed pipe for inserting into the tanker discharge pipe. A regulating valve is installed on the surface of the second feed pipe for regulating the pressure at the second feed pipe.

[0006] Preferably, the support includes a support plate mounted on the surface of the pressure stabilizing tank, a support base mounted on the top of the support plate, an installation sleeve mounted on the surface of the second feed pipe, an adjustment plate mounted on the bottom of the installation sleeve, and the adjustment plate is inserted into the support base with an adjustable insertion depth.

[0007] Preferably, the surface of the adjusting plate is provided with a plurality of insertion holes, and the surface of the support base is provided with a limiting part, which is used to insert into the insertion holes and to limit the adjusting plate after it is inserted into the support base.

[0008] Preferably, the limiting part includes a connecting spring mounted on the surface of the support base, a connecting plate is mounted on the end of the connecting spring, and a plug rod is mounted on the side of the connecting plate, the plug rod being inserted into the insertion hole.

[0009] Preferably, the mounting sleeve has mounting plates symmetrically mounted on its sides, and clamping elements are mounted on the mounting plates for clamping the tanker truck's discharge pipe.

[0010] Preferably, the clamping member includes a threaded sleeve mounted on the top of the mounting plate, a threaded rod threadedly connected to the inner wall of the threaded sleeve, the end of the threaded rod extending to the bottom of the mounting plate, and a clamping block rotatably connected to the end of the threaded rod via a bearing, the clamping block contacting the top of the tanker truck's discharge pipe.

[0011] Preferably, a guide rod is installed on the top of the clamping block, and the guide rod is connected through the mounting plate.

[0012] Compared with the prior art, this utility model provides a liquid reagent tanker unloading device for sewage treatment plants, which has the following beneficial effects:

[0013] This wastewater treatment plant's liquid reagent tanker unloading device, through the installation of an adjustable-height support and a corresponding limiting structure, can flexibly adjust the position of the second inlet pipe according to the height of different tanker discharge pipes. The limiting structure, by fixing the adjusting plate, ensures the stability of the second inlet pipe's height. Simultaneously, the installed clamping components effectively clamp the tanker discharge pipe, preventing the insert pipe from detaching from the tanker discharge pipe during unloading. These design features work together to avoid liquid reagent leakage caused by unstable connections, ensuring a safe and reliable unloading process and reducing safety risks and material loss.

[0014] The liquid reagent tanker unloading device at this wastewater treatment plant achieves height adjustment through the cooperation of an insertion hole and a limiting part. Operators simply need to pull the connecting plate to disengage the insertion rod from the insertion hole to easily adjust the position of the adjusting plate. After adjustment, releasing the connecting plate allows the insertion rod to automatically insert into the insertion hole under spring pressure, completing the limiting operation. The operation is simple and quick. The clamping component uses a threaded rod and threaded sleeve design. Rotating the threaded rod allows the clamping block to move up and down, thus clamping and releasing the tanker's discharge pipe. No complicated tools or cumbersome procedures are required, greatly improving the ease of operation and saving operating time and labor costs. Attached Figure Description

[0021] To more clearly and completely illustrate the technical solution of this utility model, the following description, in conjunction with the accompanying drawings, will further explain this utility model. Example

[0022] like Figures 1-5 As shown in the figure, an embodiment of this utility model discloses a liquid chemical tanker unloading device for a wastewater treatment plant, comprising a pressure stabilizing tank 1 and a tanker discharge pipe 5 connected to the tanker. A discharge pipe 2 and a feed section 3 are installed at the bottom of the pressure stabilizing tank 1. The discharge pipe 2 is used to discharge the material inside the pressure stabilizing tank 1, and the feed section 3 is used to introduce the liquid chemical from the tanker into the pressure stabilizing tank 1. The feed section 3 includes a first feed pipe 31 installed on the surface of the pressure stabilizing tank 1. A connecting hose 32 is installed at the end of the first feed pipe 31. The connecting hose 32 can be bent and moved to facilitate connection to components at different locations. A second feed pipe 33 is installed at the end of the connecting hose 32. A support part 4 is installed at the bottom of the second feed pipe 33. The support part 4 supports the second feed pipe 33, and its height is adjustable to meet the height requirements of different tanker discharge pipes 5. An insertion pipe 34 is installed at the end of the second feed pipe 33. The insertion pipe 34 can be inserted into the tanker discharge pipe 5 to introduce the liquid chemical. A regulating valve 35 is installed on the surface of the feed pipe 2 33. By adjusting the regulating valve 35, the pressure at the feed pipe 2 33 can be adjusted, thereby controlling the inflow rate and flow rate of the liquid agent. In actual use, the insertion pipe 34 is inserted into the tank truck discharge pipe 5, the height of the support part 4 is adjusted to stabilize the device, and then the regulating valve 35 is used to control the smooth flow of the liquid agent into the pressure stabilizing tank 1.

[0023] In this invention, the support part 4 includes a support plate 41 mounted on the surface of the pressure stabilizing tank 1, providing a stable mounting base for the entire support part 4. A support seat 42 is mounted on the top of the support plate 41, and an installation sleeve 44 is mounted on the surface of the feed pipe 33. An adjusting plate 43 is mounted on the bottom of the installation sleeve 44. The adjusting plate 43 is inserted into the support seat 42, and the insertion depth is adjustable. For example, the height of the feed pipe 33 can be adjusted by changing the insertion depth of the adjusting plate 43 into the support seat 42 according to the height of the tank truck discharge pipe 5, ensuring that the insertion pipe 34 can be accurately inserted into the tank truck discharge pipe 5 and guaranteeing normal feeding of the device.

[0024] In this invention, the surface of the adjusting plate 43 is provided with multiple insertion holes 431, and the surface of the support base 42 is equipped with a limiting part. The limiting part is used to insert into the insertion hole 431 to limit the adjustment plate 43 after it is inserted into the support base 42. After adjusting the depth of the adjusting plate 43 inserted into the support base 42, the limiting part is inserted into the corresponding insertion hole 431 to prevent the adjusting plate 43 from sliding during the use of the device, ensuring the height stability of the feed pipe 33, and thus ensuring the stable connection between the insertion pipe 34 and the tank truck discharge pipe 5, so that the liquid medicine can be smoothly introduced into the pressure stabilizing tank 1.

[0025] In this invention, the limiting part includes a connecting spring 421 mounted on the surface of the support base 42. A connecting plate 422 is mounted on the end of the connecting spring 421, and a plug rod 423 is mounted on the side of the connecting plate 422. The plug rod 423 is inserted into the insertion hole 431. When adjusting the insertion depth of the adjusting plate 43, the connecting plate 422 is pulled first, causing the connecting spring 421 to stretch, and the plug rod 423 is pulled out of the insertion hole 431. At this time, the position of the adjusting plate 43 can be freely adjusted. After adjusting to the appropriate position, the connecting plate 422 is released. Under the elastic force of the connecting spring 421, the plug rod 423 is inserted into the corresponding insertion hole 431, thereby limiting the adjustment plate 43, ensuring the stability of the device structure, and allowing the unloading process to proceed smoothly.

[0026] In this invention, mounting plates 6 are symmetrically mounted on the sides of the mounting sleeve 44, and clamping members 7 are installed on the mounting plates 6. The clamping members 7 are used to clamp the tank truck discharge pipe 5. When the insertion tube 34 is inserted into the tank truck discharge pipe 5, the clamping members 7 are operated to firmly clamp the tank truck discharge pipe 5, preventing the insertion tube 34 from detaching from the tank truck discharge pipe 5 during the unloading process, avoiding leakage of liquid agents, and ensuring the safe and reliable unloading operation.

[0027] In this invention, the clamping component 7 includes a threaded sleeve 71 mounted on the top of the mounting plate 6. A threaded rod 72 is threadedly connected to the inner wall of the threaded sleeve 71. The end of the threaded rod 72 extends to the bottom of the mounting plate 6. A clamping block 73 is rotatably connected to the end of the threaded rod 72 via a bearing. The clamping block 73 contacts the top of the tanker truck discharge pipe 5. When it is necessary to clamp the tanker truck discharge pipe 5, the threaded rod 72 is rotated. Because the threaded rod 72 is threadedly connected to the threaded sleeve 71, the threaded rod 72 moves downward, causing the clamping block 73 to move downward, thereby tightly pressing the tanker truck discharge pipe 5, achieving clamping and fixing of the tanker truck discharge pipe 5, and ensuring a stable connection between the device and the tanker truck discharge pipe 5 during the unloading process.

[0028] In this invention, a guide rod 74 is installed on the top of the clamping block 73, and the guide rod 74 is connected through the mounting plate 6. When the threaded rod 72 is rotated to move the clamping block 73 up and down, the guide rod 74 acts as a guide to prevent the clamping block 73 from deflecting during the movement, ensuring that the clamping block 73 can move vertically downwards and accurately clamp the tank truck discharge pipe 5, improving the stability and reliability of the clamping, and ensuring that the unloading process is not affected.
