Description

Technical Field

[0001] The utility model relates to the technical field of spray devices, in particular to a hopper high-pressure spray device. Background Art

[0002] A hopper is a device used to store and convey granular or powdered materials. It is typically funnel-shaped, wide at the top and tapering at the bottom to facilitate material flow. It is widely used in industrial production, agriculture, construction, and other fields. Its primary function is to facilitate the storage, distribution, and conveying of materials. The feed hopper easily generates dust during operation, necessitating a spray system to reduce dust within the hopper.

[0003] For example, an automatic dust removal device for spraying a feed hopper with application number CN210021531U includes a feed hopper and a spray device, wherein the spray device includes a left base, a right base, a spray pipe, a spray head water pipe, and a water pipe switch, wherein the right base includes a clamping plate, a fixed column, an elastic box, a slide plate, a pull ring, and an elastic ball, and the water pipe switch includes a switch box, a fixed block, a top plate, a top column, an elastic block, a connecting column, an inclined plate, an elastic device, a rotating plate, a guide column, and a receiving plate. By setting the inclined plate, rotating plate, connecting column, top column, and top plate, the inclined plate is subjected to pressure and moves to the left at its lower end, thereby causing the bottom of the rotating plate to move to the left, and then causing the top of the rotating plate to move to the right, thereby causing the connecting column to move to the left, and then causing the top column to move to the left, so that the water pipe can circulate, and then the spray device starts to work, thereby facilitating the automatic operation of the spray device and saving water resources.

[0004] The above patent proposes that under the elastic action of the elastic block, the top column moves to the left, and the top plate moves to the left accordingly, blocking the water pipe and causing the spray device to stop working. However, in actual operation, as the amount of feed decreases, the amount of dust generated during the feeding process becomes less, and the amount of spray water cannot be controlled, which will lead to waste of water resources and inconvenience in use.

[0005] Therefore, we propose a hopper high-pressure spraying device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a hopper high-pressure spray device to solve the problem proposed in the background art that the amount of dust generated during the feeding process is reduced, the amount of spray water output is uncontrollable, and water resources are wasted.

[0008] A base frame is installed at the bottom end of the high-pressure plunger pump, a detection groove is opened on one side of the base frame, an L-shaped drawer plate is slidably installed on the inner wall of the detection groove and inside the base frame, and a photoelectric sensor and a single-chip microcomputer are installed at the bottom end of the detection groove.

[0009] Preferably, a liquid level gauge is installed on the outside of the water tank, a liquid level switch is provided inside the water tank, a protection box is installed on the outside of the water tank, and a PLC is installed inside the protection box.

[0013] Preferably, a detection frame is installed on the top end of the three-way pipe, and a dust sensor is installed on the outer surface of the detection frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) The utility model provides a hopper high-pressure spray device. When the door machine moves to the top of the hopper, the photoelectric sensor senses the signal and transmits it to the single-chip microcomputer. The single-chip microcomputer controls the high-pressure plunger pump to operate.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1: Please refer to Figure 1-Figure 3 A hopper high-pressure spraying device includes a spraying structure 1. The spraying structure 1 includes a water tank 11 and a high-pressure plunger pump 12 arranged on one side of the water tank 11. A water pumping pipe 13 is installed at the water pumping end of the high-pressure plunger pump 12, and a water scattering component 14 is installed above the water pumping pipe 13. The high-pressure plunger pump 12 is used to transport liquid into the water scattering component 14 under high pressure. The liquid is sprayed through the water scattering component 14, thereby achieving the effect of reducing dust inside the hopper.

[0024] A base frame 121 is installed at the bottom end of the high-pressure plunger pump 12, and a detection groove 122 is opened on one side of the base frame 121. An L-shaped drawer plate 123 is slidably installed on the inner wall of the detection groove 122 and inside the base frame 121. A photoelectric sensor 124 and a single-chip computer 125 are installed at the bottom end of the inner part of the detection groove 122. After the photoelectric sensor 124 detects that the door machine moves above the hopper, the single-chip computer 125 can control the opening of the high-pressure plunger pump 12.

[0025] A liquid level gauge 111 is installed on the outside of the water tank 11, a liquid level switch 112 is provided inside the water tank 11, a protective box 113 is installed on the outside of the water tank 11, and a PLC 114 is installed inside the protective box 113. The model adopted by the PLC 114 is S7-1200. The PLC 114 is electrically connected to the high-pressure plunger pump 12 to protect the entire spray structure 1 to prevent the high-pressure plunger pump 12 from being evacuated. The plunger and other internal components of the pump will generate excessive heat due to friction, and long-term operation may cause overheating and damage the pump body and internal parts.

[0026] In this embodiment, one end of the L-shaped draw plate 123 is pushed into the interior of the base frame 121, and the photoelectric sensor 124 detects the top of the hopper. When the door machine moves to the top of the hopper, the light beam will be blocked, thereby triggering the photoelectric sensor 124. The photoelectric sensor 124 senses the signal and transmits it to the single-chip microcomputer 125. The single-chip microcomputer 125 controls the high-pressure plunger pump 12 to operate. The high-pressure plunger pump 12 operates to extract water from the inside of the spray structure 1 through the water pumping pipe 13. The liquid level meter 111 and the liquid level switch The setting of 112 is used for PLC114 to monitor the liquid level of the water tank 11 to achieve water cut-off protection. After the door machine moves away from above the hopper, the photoelectric sensor 124 senses the movement of the door machine, the high-pressure plunger pump 12 stops operating, and the water supply to the water-spreading component 14 is turned off. After the power supply to the spray structure 1 is turned off, the L-shaped drawer 123 moves to the top of the photoelectric sensor 124 to protect the photoelectric sensor 124 and the single-chip computer 125. By coordinating the use of the photoelectric sensor 124 and the door machine, the waste of water resources is reduced.

[0027] Example 2: Please refer to Figure 4 The water-dispersing component 14 includes a tee pipe 141 installed at the water outlet end of the high-pressure plunger pump 12. Insulation pipes 142 are installed at both ends of the tee pipe 141. There are four groups of insulation pipes 142, and connecting elbows 143 are installed between the insulation pipes 142. The tee pipe 141 diverts water, and the connecting elbow 143 connects one end of the two groups of insulation pipes 142.

[0028] A safety valve 144 is installed at the top of the connecting elbow 143, and an emptying valve 147 is installed at the bottom end of the insulation pipe 142. When the internal pressure of the pipeline exceeds the preset safety limit, the connecting elbow 143 protects the equipment from overpressure damage by automatically releasing excess pressure. The set emptying valve 147 can be opened after the use of the spray structure 1 is finished to drain the water in the pipeline.

[0029] A nozzle A145 is installed through the top of the insulation pipe 142, and a nozzle B146 is installed through the outer surface of the insulation pipe 142. The nozzle A145 adopts the model D-5, and the water is fan-shaped atomized. The nozzle B146 adopts the model H-10, and the water is long-distance atomized.

[0030] A detection frame 148 is installed at the top end of the three-way pipe 141, and a dust sensor 149 is installed on the outer surface of the detection frame 148. The dust sensor 149 detects the amount of dust generated when the material is put into the device.

[0031] In this embodiment: the dust sensor 149 detects the amount of dust generated by the feeding. When the powder output becomes smaller and smaller, the signal detected by the dust sensor 149 is transmitted to the single-chip microcomputer 125 to control the pumping speed of the high-pressure plunger pump 12, the water volume is reduced, and the water spraying volume of the nozzle B146 and the nozzle A145 is reduced. When the water-dispersing component 14 is used normally, the nozzle A145 sprays a fan-shaped water mist to limit the diffusion range of the dust, and the long-distance water mist sprayed by the nozzle B146 reduces the dust at the center of the hopper and reduces the height of the dust. The safety valve 144 provided at the top of the connecting elbow 143 provides pressure protection for the inside of the insulation pipe 142 and the connecting elbow 143. When the high-pressure plunger pump 12 stops supplying water, the drain valve 147 opens to drain the water inside the insulation pipe 142 and the connecting elbow 143.

[0032] Working principle: When the door machine moves to the top of the hopper, the photoelectric sensor 124 senses the signal and transmits it to the single-chip computer 125. The single-chip computer 125 controls the high-pressure plunger pump 12 to operate. The setting of the liquid level meter 111 and the liquid level switch 112 is used for PLC114 to monitor the liquid level of the water tank 11 to achieve water cut-off protection. The photoelectric sensor 124 is used in conjunction with the door machine to reduce the waste of water resources. When the powder production becomes smaller and smaller, the signal detected by the dust sensor 149 is transmitted to the single-chip computer 125 to control the pumping speed of the high-pressure plunger pump 12. The water spraying volume of nozzle B146 and nozzle A145 is reduced to avoid waste of water resources.
