Description

Technical Field

[0001] The utility model relates to the technical field of automatic pumping, in particular to an automatic pumping system. Background Art

[0002] The water level control in a reservoir or a water seal pool is an important link in the operation process. The existing liquid level control systems, such as the water level control system for a reservoir disclosed in Chinese patent document CN 110658859 A (application number 201910925863.2), realizes the automatic control of the water level through a liquid level detection mechanism arranged inside the reservoir. However, the coking plant coke oven gas condensate contains a large amount of oil. If the device provided by the above patent is used, the liquid level detection mechanism will be in direct contact with the corrosive condensate, resulting in damage to the device and inability to ensure long-term stable operation. At the same time, since the condensate flow rate cannot be pre-cooled in advance, when the condensate flow rate changes greatly and the pumping device cannot handle it in time, the above water level control system cannot notify the staff in time. If a water overflow accident occurs, a large amount of manpower and material resources will be wasted for treatment.

[0003] Therefore, there is an urgent need for a new safe and effective pumping system to ensure the liquid level stability of the coke oven gas condensate water seal pool. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above-mentioned deficiencies of the prior art and provide an automatic water pump. Only the floating ball and part of the floating ball rod are located below the placing plate in the device, which greatly avoids the corrosion of the device.

[0005] To achieve the above technical effects, the utility model adopts the following technical solutions:

[0006] An automatic pumping system includes a placing plate and a floating ball liquid level assembly.

[0007] The floating ball liquid level assembly includes a floating ball, a floating ball rod and a trigger rod. The floating ball is fixed at the bottom end of the floating ball rod. A vertically penetrating floating ball hole is opened on the placing plate. The floating ball rod can move vertically in the floating ball hole. The trigger rod is vertically fixed on the top surface of the placing plate. A triggering device is arranged on the floating ball rod. Starting limit and stopping limit matched with the triggering device are arranged on the trigger rod. The starting limit is located above the stopping limit.

[0008] Both the starting limit and the stopping limit are electrically connected to an external water pump device. The starting limit and the stopping limit respectively make the water pump device start and stop according to the triggering of the triggering device.

[0009] In the pumping system provided by the present utility model, only the float ball and part of the float ball rod are located below the placement board, which avoids the corrosion of the whole device during use, effectively extends the service life of the device, and at the same time, drives the float ball rod and the trigger device through the float ball to automatically control the water pump, reducing labor costs.

[0010] Preferably, the trigger device is fixed on the float ball rod through a horizontally arranged connecting rod.

[0011] Preferably, the trigger rod includes a first trigger rod and a second trigger rod. The start limit is fixed on the first trigger rod, and the stop limit is fixed on the second trigger rod.

[0012] Preferably, an alarm is further provided on the placement board. The alarm is fixed on the top surface of the placement board by an alarm housing. An alarm pull rope is provided between the alarm and the trigger device. When the trigger device is above the start limit, the alarm pull rope drives the alarm to give an alarm.

[0013] By setting the alarm and the alarm pull rope between the alarm and the trigger device, if the external water pump device fails to be started in time or the liquid level rises rapidly, the alarm will give an alarm in time to guide the staff to perform manual processing.

[0014] Preferably, the trigger rod further includes a third trigger rod and a fourth trigger rod. Rope fixing rods are respectively provided on the third trigger rod and the fourth trigger rod, and the rope fixing rods are used to limit the position of the alarm pull rope.

[0015] Preferably, a vertically penetrating chute is opened on the placement board. The chute communicates the float ball hole with the outside of the placement board. A stop block for restricting the horizontal position of the float ball rod is provided on the float ball hole.

[0016] Further preferably, the float ball is detachably fixed at the bottom end of the float ball rod.

[0017] By setting the chute communicating with the outside, the float ball rod can be disassembled and maintained as needed during use. During normal use, the stop block restricts the float ball rod to move vertically up and down inside the float ball hole, effectively avoiding the influence of the chute on the liquid level monitoring effect.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. The automatic pumping system provided by the present utility model has a simple structure, realizes precise control of the liquid level through the float ball liquid level assembly, ensures that water storage devices such as water storage tanks or water seal tanks are in a reasonable water level state, and saves labor costs.

[0020] 2. By setting the sliding groove, the float rod in the float liquid level assembly can be disassembled and maintained as needed during use. During normal use, the stop block restricts the float rod inside the float hole to move vertically up and down, effectively avoiding the influence of the sliding groove on the liquid level monitoring effect.

Detailed Embodiments

[0024] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0025] Embodiment 1

[0026] An automatic pumping system, as Figure 1 and Figure 2 shown, includes a storage board 1 and a float liquid level assembly.

[0027] The float liquid level assembly includes a float, a float rod 3 and a trigger rod. The float 14 is fixed at the bottom end of the float rod 3. A vertically penetrating float hole 2 is opened on the storage board 1. The float rod 3 can move vertically in the float hole 2. The trigger rod is vertically fixed on the top surface of the storage board 1. A trigger device 9 is provided on the float rod 3. The trigger device 9 is fixed on the float rod 3 through a horizontally arranged connecting rod 8. Start limit 10 and stop limit 11 that are matched with the trigger device 9 are provided on the trigger rod. The start limit 10 is located above the stop limit 11. In this embodiment, the cooperation mode of the trigger device 9 with the start limit 10 and the stop limit 11 is a spring contact switch. Those skilled in the art can also select other cooperation modes that can achieve the same trigger function during specific use.

[0028] Both the start limit 10 and the stop limit 11 are electrically connected to an external water pump device. The start limit 10 and the stop limit 11 respectively cause the water pump device to start and stop according to the trigger of the trigger device 9.

[0029] In this embodiment, the trigger rod includes a first trigger rod 5 and a second trigger rod 7. The start limit 10 is fixed on the first trigger rod 5, and the stop limit 11 is fixed on the second trigger rod 7. An alarm 15 is also provided on the storage plate 1. The alarm 15 is fixed on the top surface of the storage plate 1 by an alarm housing 16. In this embodiment, the alarm 15 is fixed on the second trigger rod 7. An alarm pull rope 18 is provided between the alarm and the trigger device 9. When the trigger device 9 is above the start limit 10, the alarm pull rope 18 drives the alarm to give an alarm.

[0030] A vertically penetrating chute 17 is formed on the storage plate 1. The chute 17 communicates the float hole 2 with the outside of the storage plate 1. A stop block (not shown in the figure) for restricting the horizontal position of the float rod 3 is provided on the float hole 2. The float 14 is detachably fixed to the bottom end of the float rod 3.

[0031] By providing the chute 17 communicating with the outside, the float rod 3 can be disassembled and maintained as needed during use. During normal use, the stop block restricts the float rod 3 to move vertically up and down inside the float hole 2, effectively avoiding the influence of the chute 17 on the liquid level monitoring effect.

[0032] In this embodiment, both the float 14 and the float rod 3 are made of commonly used commercially available corrosion-resistant materials.

[0033] During specific use, the storage plate 1 is placed on the top of the water seal pool in the coking plant. According to the depth of the water seal pool and the need for water level control, the positional relationship of the trigger device 9, the start limit 10, and the stop limit 11 and the length of the alarm pull rope 18 are adjusted. In the initial state, the external water pump device is in the off state. When the water level in the water seal pool rises and drives the float 14 and the float rod 3 to rise, the trigger device 9 first contacts the start limit 10. The start limit 10 is triggered to turn on the water pump device, and the wastewater in the water seal pool is discharged outward. During the process of the water level dropping, when the trigger device 9 drops to the stop limit 11 along with the float rod 3, the stop limit 11 is triggered to turn off the water pump device. As the water level in the water seal pool rises, the above-mentioned process is repeated continuously.

[0034] If the water level rises rapidly or the water pump device fails to start normally, the float rod 3 continues to rise. At this time, the trigger device 9 drives the alarm pull rope 18 to make the alarm 15 give an alarm, guiding the staff to come and handle it in time to prevent the wastewater from overflowing.

[0035] During use, if maintenance of the float 14 is required, the stop block is removed, and the float rod 3 is horizontally moved out of the storage plate 1 to perform the operation.
