Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to an automatic wastewater pumping device. Background Technology
[0002] The metallurgical industry generates large amounts of wastewater containing oil or other impurities during production. This wastewater typically collects in sludge pits. The existing devices used to pump this wastewater are float-mounted automatic pumps, which work in conjunction with float level gauges. After a period of use, oil and impurities accumulate on the floats, affecting their normal function and leading to inaccurate level measurements. This causes the automatic pumping function to malfunction, requiring manual cleaning of the oil and impurities to restore operation. Furthermore, inaccurate level measurements can easily damage the pumps, increasing spare parts and labor costs, and also increasing the workload for workers. Therefore, a new pumping device is urgently needed to solve these problems. Utility Model Content
[0003] The purpose of this invention is to provide an automatic wastewater pumping device that can solve the problem that after a period of use, oil and impurities will adhere to the float of the original float-type automatic pumping pump, affecting the normal function of the float, resulting in inaccurate liquid level measurement and failure of the automatic pumping function.
[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: This automatic wastewater pumping device includes a straight rod level gauge, a level gauge mounting bracket, an automatic control box, and a pump; the level gauge mounting bracket is provided with a positioning hole, the straight rod level gauge is inserted into the positioning hole, and a telescopic adjustment rod is provided on one side of the level gauge mounting bracket; the signal output terminal of the straight rod level gauge is connected to the input port of the automatic control box, and the control motor of the pump is connected to the output port of the automatic control box.
[0005] A more specific technical solution than the above-mentioned technical solution may be: the inner ring wall of the positioning hole is provided with a groove, and the outer ring wall of the upper part of the straight rod level gauge is provided with a protruding ring for being fitted into the groove.
[0006] Furthermore, the straight rod level gauge has a measuring rod in its lower middle part.
[0007] Furthermore, the automatic control box is equipped with an intelligent digital / light bar display controller, which is used to control the operation of the water pump based on the measurement signal of the straight rod level gauge.
[0008] Furthermore, a conduit is provided on the outside of the level gauge mounting bracket for housing the wiring of the straight rod level gauge.
[0009] Furthermore, the telescopic adjustment rod includes an outer tube and an inner rod, the inner rod is inserted into the outer tube and can slide axially relative to the outer tube; the outer tube is provided with a threaded through hole, and a positioning bolt is inserted into the threaded through hole.
[0010] Furthermore, both the straight rod level gauge and the level gauge mounting bracket are made of corrosion-resistant materials.
[0011] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:
[0012] In use, the level gauge mounting bracket is erected on the edge of the sewage pit. The measuring rod of the straight rod level gauge is placed in the sewage pit to measure the liquid level. The length of the telescopic adjusting rod is adjusted according to the specific conditions of the sewage pit. After determining the length, the positioning bolts are tightened to fix the outer tube and inner rod of the telescopic adjusting rod. Based on the structural characteristics of the straight rod level gauge, which uses a measuring rod to measure the liquid level, it is not easily affected by oil and impurities, ensuring accurate liquid level measurement and preventing the automatic pumping function from failing. The automatic control box uses an intelligent digital / light bar display controller in conjunction with the straight rod level gauge, which can accurately control the water level to the centimeter. It sets a low level to start the pumping, and stops the pumping when the level is low enough, issuing an alarm signal to ensure the pump does not run dry and is not burned out. This effectively reduces spare parts and labor costs, and also reduces the labor intensity of workers. Attached Figure Description

[0014] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model; however, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0015] like Figure 1 The wastewater automatic pumping device shown includes a straight rod level gauge 1, a level gauge mounting bracket 2, an automatic control box, and a pump. The level gauge mounting bracket 2 has a positioning hole, and the straight rod level gauge 1 is installed in the positioning hole. A telescopic adjustment rod is provided on one side of the level gauge mounting bracket 2. The signal output terminal of the straight rod level gauge 1 is connected to the input port of the automatic control box, and the control motor of the pump is connected to the output port of the automatic control box. The automatic control box is equipped with an intelligent digital / light bar display controller, which is used to control the operation of the pump based on the measurement signal of the straight rod level gauge 1.
[0016] The inner ring wall of the positioning hole is provided with a groove, and the outer ring wall of the upper part of the straight rod level gauge 1 is provided with a protruding ring 1-1 for being fitted into the groove. The groove and the protruding ring 1-1 can be fixed relative to each other by screws or pins. The straight rod level gauge 1 is provided with a measuring rod 1-2 in the lower middle part.
[0017] The outer side of the level gauge mounting bracket 2 is equipped with a conduit 3 for placing the wiring of the straight rod level gauge 1.
[0018] The telescopic adjustment rod includes an outer tube 4 and an inner rod 5. The inner rod 5 is inserted into the outer tube 4 and can slide axially relative to the outer tube 4. The outer tube 4 is provided with a threaded through hole, and a positioning bolt is installed in the threaded through hole.
[0019] Both the straight rod level gauge 1 and the level gauge mounting bracket 2 are made of corrosion-resistant materials, which can improve the service life of this utility model.

[0021] In use, the level gauge mounting bracket 2 is placed on the edge of the sewage pit.

The automatic control box uses an intelligent digital / light bar display controller in conjunction with the straight rod level gauge, which can accurately control the water level to the centimeter. It sets the pump to start pumping water when the level is low, and stops pumping water when the level is very low, issuing an alarm signal to ensure that the pump does not run dry and is not burned out. This effectively reduces spare parts and labor costs, and also reduces the labor intensity of workers.
