Description

Technical Field

[0001] The utility model relates to the technical field of liquid level control, and more specifically, to a liquid level automatic control water pumping device. Background Art

[0002] An automatic liquid level control pumping device usually refers to a system that can automatically start or stop the pump according to the set liquid level height to maintain the liquid level within the required range. It is composed of sensors, controllers, actuators and feedback systems to achieve automatic monitoring and control of the liquid level, ensuring stable operation of the system and meeting the needs of industrial or personal use.

[0003] The liquid level automatic control pumping device does play a vital role in the chemical, food, biomedicine and other industries. A large amount of sewage will be generated in the production process. The sewage will be discharged into the sewage treatment pool for treatment first. In actual treatment, the sewage will be discharged into multiple sewage pools, and a certain amount of coagulant and other treatment agents will be added to each sewage pool. In order to ensure the effect and efficiency of sewage treatment, the liquid level of the sewage in each sewage pool needs to be at or below the liquid level line.

[0004] In the process of discharging sewage into a sewage pool, the sewage is first discharged into a sewage pool. When the sewage in the sewage pool reaches the standard liquid level line, it is pumped into other sewage pools through a pumping device for treatment. However, due to the large production volume of large factories, it is necessary to manually observe the situation in the sewage pool at all times and frequently operate the pumping device, which is cumbersome to operate. If the staff makes omissions in their work, sewage may overflow.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a liquid level automatic control water pumping device. Utility Model Content

[0009] Preferably, the delivery pipe is used to discharge wastewater generated in production into a sewage pool.

[0010] Preferably, a baffle is installed in the inner cavity of the sewage pool, and the baffle is used to separate the float from the delivery pipe to prevent the sewage from directly impacting the float when the delivery pipe delivers sewage to the sewage pool, causing the float to float unstably. Multiple groups of through holes are opened at the bottom of the baffle to keep the various parts in the sewage pool connected and the liquid levels at the same height.

[0011] Preferably, the length from the float on the connecting rod to the rotating shaft is greater than the length from the balancing block to the rotating shaft, the mass of the balancing block is greater than the float, and with the rotating shaft as the center, the weights of the two parts of the connecting rod are equal, reducing the influence of deadweight.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. In the utility model, by setting a detection component, the change of the liquid level in the sewage pool is converted into the change of the float and the balance block. The balance block can affect the connection between the infrared receiver and the infrared transmitter. The infrared receiver can control the switch of the water pump. When the infrared receiver can receive the infrared signal of the infrared transmitter, the water pump is turned off. When the infrared receiver cannot receive the infrared signal of the infrared transmitter, the water pump starts to pump water from the sewage pool to keep the sewage in the sewage pool always at or below the standard liquid level line. The whole process does not require manual participation, which reduces labor costs and the probability of accidents. It solves the problem mentioned in the background technology that due to the large production volume of large factories, it is necessary to manually observe the situation in the sewage pool at all times and frequently operate the pumping device, which is troublesome to operate, and if the staff makes omissions in their work, the sewage may overflow.

In the utility model, a baffle is provided and a plurality of through holes are opened at the bottom of the baffle to separate the float from the delivery pipe, so as to prevent the sewage from directly impacting the float when the delivery pipe delivers sewage to the sewage pool, thereby causing the float to float unstably.

[0022] like Figure 1-5As shown, the utility model provides a liquid level automatic control water pumping device, including a sewage pool 1 and a delivery pipe 4, the delivery pipe 4 is used to discharge the sewage generated by production into the sewage pool 1, a water pump 6 is installed on the sewage pool 1, the water pumping end of the water pump 6 is connected to a water pumping pipe 5, the water delivery end of the water pump 6 is connected to a water delivery pipe 7, the water pumping pipe 5 extends into the bottom of the inner cavity of the sewage pool 1, and the water delivery pipe 7 is used to transport the sewage to other sewage pools 1;

[0023] The inner cavity of the sewage pool 1 is connected to a detection box 2, and a detection component 3 is arranged in the detection box 2. The detection component 3 includes a mounting seat 304 installed in the detection box 2. The mounting seat 304 is rotatably connected to a connecting rod 302 through a rotating shaft 305. The end of the connecting rod 302 extending into the sewage pool 1 is fixedly connected to a floating ball 301, and the end of the connecting rod 302 extending into the detection box 2 is fixedly connected to a balancing block 303. An infrared transmitter 306 is installed in the detection box 2, and an infrared receiver 307 is installed in the emission direction of the infrared transmitter 306. The infrared receiver 307 is electrically connected to a water pump 6. The infrared receiver 307 can control the switch of the water pump 6. When the infrared receiver 307 can receive the infrared signal of the infrared transmitter 306, the water pump 6 is turned off. When the infrared receiver 307 cannot receive the infrared signal of the infrared transmitter 306, the water pump 6 starts Water is pumped from the sewage pool 1, and a standard liquid level line is set in the sewage pool 1. When the sewage exceeds the standard liquid level line, the float 301 also rises to the standard liquid level line, and the connecting rod 302 rotates. At this time, the balance block 303 at the other end of the connecting rod 302 just rotates between the infrared transmitter 306 and the infrared receiver 307, and the connection between the infrared transmitter 306 and the infrared receiver 307 is cut off. The infrared receiver 307 controls the water pump 6 to pump water from the sewage pool 1. After the sewage is pumped out, the liquid level drops below the standard liquid level line, and the float 301 also drops below the standard liquid level line. The connecting rod 302 rotates, and the balance block 303 no longer cuts off the infrared transmitter 306 and the infrared receiver 307, so that the sewage in the sewage pool 1 is always kept at or below the standard liquid level line. The whole process does not require manual participation, which reduces labor costs and reduces the probability of accidents.

[0024] A baffle 8 is installed in the inner cavity of the sewage pool 1. The baffle 8 is used to separate the float 301 from the delivery pipe 4 to prevent the sewage from directly impacting the float 301 when the delivery pipe 4 delivers sewage to the sewage pool 1, causing the float 301 to float unstably. A plurality of through holes 9 are provided at the bottom of the baffle 8 to keep the various parts in the sewage pool 1 connected and the liquid levels at the same height.
