Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment equipment control devices, and particularly relates to a rod type travel switch liquid level gauge device. Background Art

[0002] Metallurgical enterprises have a large amount of production water consumption, and the disposal of production wastewater is an important link to avoid energy waste. Taking the coal cooling tower as an example, the coal cooling tower cools and dedusts the flue gas generated by converter smelting through gas-water spraying. The generated wastewater is recycled after cooling. When the recycling frequency is high and the water quality does not meet the standard, this part of the wastewater will be centrally stored, and when the water level rises to the upper limit, it will be discharged to the sewage treatment plant.

[0003] Currently, the start and stop of water pumps are controlled by common floating ball liquid level controllers on the market. When the floating ball floats to the set upper limit along with the liquid level, the water pump starts to discharge the wastewater. When the water level drops, the floating ball drops to the lower limit and the water pump stops.

[0004] Currently, the traditional floating ball liquid level controller has the following disadvantages:

[0005] First, the signal sensing of the floating ball is transmitted through a cable. If the outer shell is damaged, it will cause electric leakage.

[0006] Second, the floating ball device has a small volume. When the water injection pool is filled with water, the liquid level fluctuates greatly, and the floating ball is easily stuck in positions such as pipelines and brackets, resulting in control failure.

[0007] Therefore, a rod type travel switch liquid level gauge device is proposed. Content of the Utility Model

[0010] Preferably, two sets of travel switches are provided, one set is a self-starting upper switch, and the other set is a self-stopping lower switch. The two sets of travel switches are arranged up and down and are both installed on the outer wall of the limiting cylinder.

[0022] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the following will further illustrate the present utility model with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited to the limitations of the specific embodiments disclosed in the following specification.

[0024] Embodiment 1, as Figure 1-2 shown, a rod-type travel switch liquid level gauge device includes a fixed rod 1. The fixed rod 1 provides support and a "track" for up and down movement, has good shock resistance, and avoids shaking or displacement. The bottom of the fixed rod 1 is connected to a fixed seat 2. The fixed seat 2 firmly fixes the fixed rod 1, provides a solid foundation, and prevents the influence of water flow fluctuations.

[0025] A sleeve 3 is sleeved on the fixed rod 1. The sleeve 3 covers the outside of the fixed rod 1 and can slide up and down along the fixed rod 1 following the water level. A stop disk 4 is provided at the top of the sleeve 3. The stop disk 4 extends outward in a disk shape. The stop disk 4 can move following the up and down floating of the sleeve 3. A float 5 is provided outside the sleeve 3. The float 5 has a certain buoyancy and can float up and down following the rise and fall of the liquid level, reflecting the water level change. The float 5 is relatively large, overcoming the problem that the traditional floating ball liquid level controller is easily stuck due to its small volume, and can adapt to a water level environment with large fluctuations, ensuring reliable operation.

[0026] One end of the fixed seat 2 is provided with a limit rod 6. The limit rod 6 provides a support rod for placing the switch. A connecting stud 7 is provided at the top of the limit rod 6.

It has high precision and sensitive response, ensuring the accuracy and stability of control. The control cable of the travel switch 9 can be laid along the threading pipe to the control box.

[0029] The fixed seat 2 is fixed at the bottom of the water tank by pouring or welding. The fixed rod 1 and the limit rod 6 are respectively fixedly connected to the fixed seat 2. The fixed rod 1 and the limit rod 6 are connected to the fixed seat 2 as a whole.

[0030] The diameter of the sleeve 3 is slightly larger than that of the fixing rod 1, and the sleeve 3 is sleeved outside the fixing rod 1.

[0031] A threaded hole is provided at the bottom of the limiting cylinder 8, and the diameter and length of the threaded hole are set corresponding to the diameter and length of the connecting stud 7. The threaded hole ensures a tight connection with the connecting stud 7, is flexible to install, and can meet the liquid level control requirements of different water well and pool environments.

[0032] A rotating handle 10 is provided at the top of the limiting cylinder 8. The rotating handle 10 is used to adjust the position of the limiting cylinder 8 or remove the limiting cylinder 8, which is convenient for daily maintenance.
