Description

Technical Field

[0001] The utility model belongs to the technical field of bulk material loading and unloading, and specifically relates to an automatic energy-saving and environmentally friendly water supply system suitable for bucket wheel machine operation. Background Art

[0002] Bucket wheel stackers are divided into two types according to their structural type: arm type and gantry type (hereinafter referred to as bucket wheel machines). They are bulk material stacking and reclaiming equipment used in strip material yards. In recent years, as the country's environmental protection requirements have become increasingly stringent, dust control has become the key remediation work of bulk material yards. Therefore, the demand for daily spraying water for bucket wheel machines is also increasing.

[0003] At present, bucket wheel excavators conventionally adopt the form of fixed-point water supply on the machine, that is, several water supply points are set within the operating range of the bucket wheel excavator in the strip material yard. When the bucket wheel excavator water tank needs water supply, the bucket wheel excavator should be operated to the vicinity of the water supply point, and then the bucket wheel excavator water tank is filled with water through manually assembled quick fire-fighting hoses.

[0004] However, this method has the following shortcomings: the size of the water tank is usually less than 10 tons due to the space and carrying capacity of the bucket wheel machine's tail car, which means that the amount of water in the water tank is usually not enough to maintain the amount of water required for the three-shift operation of the bucket wheel machine. Therefore, the bucket wheel machine is often driven to the vicinity of the water supply point for manual connection, which is time-consuming and labor-intensive and has a low degree of automation. With the widespread application of unmanned systems in bucket wheel machines, this form of manually connecting water supply can no longer meet the needs of fully automated and efficient operation of bucket wheel machines.

[0005] Therefore, it is very necessary to develop an automatic energy-saving and environmentally friendly water supply system suitable for bucket wheel excavator operation. Utility Model Content

[0006] The purpose of the utility model is to provide an automatic energy-saving and environmentally friendly water supply system suitable for bucket wheel excavator operation, so as to solve the problem that the bucket wheel excavator with a water tank in the background technology cannot maintain the spray water consumption for long-term operation when filling with water, thereby improving work efficiency and enhancing the degree of automation.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] An automatic energy-saving and environmentally friendly water supply system suitable for bucket wheel machine operation comprises: a bucket wheel machine and a water trough, wherein the water trough is arranged along the direction of the strip material yard foundation track, the bucket wheel machine water supply pipe on the bucket wheel machine is introduced into the bottom of the water trough for water supply, a double float switch is arranged at a position of the water trough close to the ground cable transfer box of the bucket wheel machine for monitoring the high and low water levels of the water trough and transmitting the high and low water level signals to the driver's cab or the remote control end, a water supply pipe is arranged at either terminal of the water trough, the water supply pipe is controlled to open and close by a Y-type filter ball valve, a float valve is arranged at the connection between the water supply pipe and the water trough, the float of the float valve is placed in the water trough, the valve body of the float valve is connected to the water supply pipe, the incoming water enters the water trough through the water supply pipe, and the float valve automatically closes when the water trough is full.

[0009] Furthermore, the water supply pipe is provided with a pressure reducing valve.

[0010] Furthermore, a dust cover is provided on the top of the water tank.

[0011] Furthermore, the dust cover is a rubber dust cover.

[0012] Furthermore, a plurality of sewage outlets are provided at the bottom of the water tank.

[0013] Furthermore, the bucket wheel excavator water supply pipe is provided with a filter and a booster pump.

[0014] Furthermore, a filter is provided at the connection between the bucket wheel machine water supply pipe and the bucket wheel machine.

[0015] Furthermore, the filter is connected to a booster pump, and the booster pump directly supplies water to the bucket wheel machine spray point or is connected to a dry fog dust suppression system for water supply.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) The utility model will first connect the water supply pipe with a Y-type filter ball valve to the water tank through a float valve, then introduce the bucket wheel machine water supply pipe into the bottom of the water tank, and finally set a double float switch in the water tank for monitoring the water level of the water tank. Such a setting realizes automatic monitoring and control of the water level of the water tank. When the water level in the water tank is lower than the set value, the float valve opens, and the water supply pipe injects water into the water tank to raise the water level to above the set value; when the water level in the water tank reaches the set value, the float valve closes, stops supplying water, and prevents the water tank from overflowing. The double float switch can determine the water level by monitoring the upper and lower float positions in the water tank, and sends out corresponding signals for control. This design realizes automatic adjustment of the water level in the water tank, ensures that there is always enough water in the water tank to supply the bucket wheel machine, and improves the stability and reliability of the water supply to the bucket wheel machine;

[0018] (2) The utility model reduces the chance of impurities in the water entering the water tank by setting a Y-type filter ball valve in the water supply pipe, and flexibly controls the water flow by controlling the opening and closing to ensure a moderate water supply. By setting a pressure reducing valve, the water pressure is effectively reduced, ensuring the normal use of the device and extending the life of the device.

[0019] (3) The utility model provides a rubber dust cover on the top of the water tank and a plurality of sewage outlets at the bottom of the water tank. On the one hand, the opportunity of dust entering the water tank during dust removal by the bucket wheel machine is increased. On the other hand, waste water and debris in the water tank are discharged through the sewage outlets, thereby ensuring the cleanliness and normal operation of the water tank.

[0020] (4) The utility model provides a filter and a booster pump at the connection between the bucket wheel machine water supply pipe and the bucket wheel machine. The former improves the cleanliness and purity of the water, protecting the normal operation and service life of the bucket wheel machine. The booster pump increases the water pressure of the water supply pipe, ensuring that the water can flow smoothly into the bucket wheel machine, enabling it to operate normally, and effectively improving the efficiency and stability of the water supply system.

[0026] like Figure 1-Figure 3In this embodiment, it includes: a bucket wheel machine and a water trough 2, the water trough 2 is arranged along the direction of the strip material yard foundation track, the bucket wheel machine water supply pipe 5 on the bucket wheel machine is introduced into the bottom of the water trough 2 for water supply, and is characterized in that: a double float switch 3 is set at the position of the water trough close to the ground cable transfer box of the bucket wheel machine, which is used to monitor the high and low water levels of the water trough and transmit the high and low water level signals to the driver's cab or the remote control end, a water supply pipe is set at any terminal of the water trough 2, and the water supply pipe is controlled to open and close by a Y-type filter ball valve 12, a float valve 10 is set at the connection between the water supply pipe and the water trough 2, the float of the float valve 10 is placed in the water trough 2, the valve body of the float valve 10 is connected to the water supply pipe, and the incoming water enters the water trough 2 through the water supply pipe. When it is full of water, the float valve 10 automatically closes.

[0027] In this embodiment, a pressure reducing valve 11 is provided on the water supply pipe.

[0028] In this embodiment, a dust cover is provided on the top of the water tank 2 .

[0029] In this embodiment, the dust cover is a rubber dust cover.

[0030] In this embodiment, a plurality of sewage outlets 4 are provided at the bottom of the water tank 2 .

[0031] In this embodiment, the bucket wheel excavator water supply pipe 5 is provided with a filter and a booster pump.

[0032] In this embodiment, a filter is provided at the connection between the bucket wheel machine water supply pipe 5 and the bucket wheel machine.

[0033] In this embodiment, the filter is connected to a booster pump, and the booster pump directly supplies water to the bucket wheel machine spray point or is connected to the dry fog dust suppression system for water supply.

[0034] Implementation process:

[0035] A double float switch 3 is set in the water tank near the ground cable transfer box of the bucket wheel machine. Its function is to monitor the high and low water levels in the water tank and transmit the high and low water level signals to the driver's cab or remote control end of the bucket wheel machine. The water tank 2 terminal is provided with a water inlet point. The incoming water can be controlled to shut down through the Y-type filter ball valve 12. After shutting down, it can not only be used for maintenance, but the filter on it can also play the role of filtering impurities in the water. If the incoming water pressure is high, the pressure of the incoming water can be reduced to the available working range of the float valve through the pressure reducing valve 11. The incoming water is controlled by the float valve 10 and automatically stops after the water tank 2 is full of water. The whole water supply system does not need electric drive and has its own high and low water level alarm. The bucket wheel machine water supply pipe 5 is directly introduced from the tail car to the bottom of the water tank. The bucket wheel machine water supply pipe 5 slides in the water tank as the bucket wheel machine runs. The rubber dust cover automatically falls after sliding over to prevent dust from entering. After the filter is installed on the bucket wheel water supply pipe 5, it is directly connected to the booster pump, and then the booster pump is used to supply water to various spray points of the bucket wheel or to connect to the dry fog dust suppression system for water supply.

[0036] During operation, when the water level in the water tank 2 is lower than the set value, the float valve 10 opens, and the water supply pipe injects water into the water tank to raise the water level to above the set value; when the water level in the water tank reaches the set value, the float valve 10 closes, stops supplying water, and prevents overflow of the water tank 2. The double float switch 3 can determine the water level by monitoring the upper and lower float positions in the water tank 2, and send corresponding signals for control.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model.
