TECHNICAL FIELD
[0001] The present disclosure belongs to the technical field of mine car transportation and environmental protection, and particularly relates to a mine car transportation high-pressure spraying dust suppression control system. BACKGROUND
[0002] In the process of mine exploitation and transportation, the environmental management requirement is very high, and the future predictable environmental requirement will be more and more strict, especially the dust control in the process of mine car transportation. Most mine cars have been required to be installed with automatic tarpaulin cover. However, the most serious dust in the process of mine car transportation is still the process of loading and unloading.
[0003] At present, mine enterprises have begun to try to install a water spraying device on the mine car box. The water spraying device adopts a small electric water pump, which is powered by the on-board battery of the mine car. However, the maximum voltage of the on-board battery of the mine car is 24V, which limits the power of the electric water pump, and there are problems such as poor spraying effect and limited spraying range. CONTENT OF THE UTILITY MODEL
[0004] In order to solve the above problems, the present disclosure provides a mine car transportation high-pressure spraying dust suppression control system. The water pump is combined with the lifting pump, and the power of the lifting pump is transmitted to the water pump. Specifically, a vane water pump is connected in series behind the vehicle lifting pump. The lifting pump and the vane water pump are coaxial. The engine power is transmitted to the lifting pump drive shaft through the gearbox power take-off. The lifting pump drives the vane water pump to rotate through the drive shaft. In the case that the lifting pump and the vane water pump share a drive shaft, the power of the vane water pump is enhanced, the spraying range is increased, and the spraying effect is improved.
[0005] The first aspect of the present disclosure provides a mine car transportation high-pressure spraying dust suppression control system. The system comprises: a lifting pump connected to the mine car gearbox through a power take-off and used for lifting the box. One end of the lifting pump is coaxially connected with a transmission shaft. A water pump is coaxially connected to the lifting pump through the transmission shaft. A spraying assembly is connected to the water pump and used for spraying the box of the mine car.
[0006] In this way, when the transmission power take-off switch is opened, the lifting pump is combined with the mine car gearbox through the power take-off. The mine car engine drives the lifting pump to work through the gearbox. Then the lifting pump drives the water pump to work through the transmission shaft, so as to provide power for the water pump to work by the mine car engine. The water pump sprays the mine car box through the spraying assembly to increase the spraying range and improve the spraying effect.
[0007] In some embodiments, the spraying assembly comprises: a spraying water tank arranged at the bottom of the mine car; a spraying pipe connected to the spraying water tank and the water pump, the spraying pipe being arranged around the mine car chassis and the box; and a spray head arranged on the spraying pipe.
[0008] The water pump is arranged to pump the water in the spray water tank to the spray head through the spray pipe, so that the spray head sprays water mist to reduce dust on the cargo box.
[0009] In some embodiments, the spray water tank has a spray opening for cooling the brake pad of the mine car.
[0010] In this way, the water pump inlet pipe can be directly installed on the spray water tank, so that the water pumped by the water pump is also sprayed from the spray opening to cool the brake pad, directly solving the water source problem, reducing the investment cost, and being economically adaptable.
[0011] In some embodiments, the spray head is a high-pressure fan-shaped spray head.
[0012] In this way, the atomization effect is good, the radiation area is wide, the number of installed spray heads is small, and the water consumption is small, which can ensure that the fan-shaped high-pressure atomization spray head has good atomization effect and saves water consumption.
[0013] In some embodiments, the spray water tank is provided with a filter screen at the pipe opening of the spray pipe.
[0014] In this way, the entry of large-particle impurities into the spray pipe to block the spray head is reduced, thereby reducing the spray blockage.
[0015] In some embodiments, the spray pipe includes a chassis pipeline, a cargo box pipeline, and a connecting hose, the connecting hose is used to connect the chassis pipeline and the cargo box pipeline, and the chassis pipeline is a transparent hard pipeline.
[0016] In this way, the pipeline can be prevented from being folded and blocked, and the transparent hard pipeline can be used to observe whether the waterway is unobstructed and whether the water supply is normal.
[0017] In some embodiments, the connecting hose is located at the hinge between the cargo box and the mine car.
[0018] In this way, the spray pipe can normally supply water to the spray head during the rotation of the cargo box, thereby facilitating the spray dust reduction of the cargo box.
[0019] In some embodiments, the cargo box pipeline is a metal pipeline, and the spray head is arranged on the cargo box pipeline.
[0020] In this way, the pipeline can be prevented from being damaged during material loading, and the spray head can be used to directly spray the inside of the cargo box to reduce dust.
[0021] Compared with the prior art, the present disclosure has the following advantages:
[0022] Through the above setting, high-pressure spraying can be realized under special conditions of the mine car, good dust suppression effect is achieved, the overall system structure is simple, technical improvement measures are few, cost investment is low, operation is stable, and operation and maintenance are easy.
[0023] Other features and advantages of the present disclosure will be set forth in the description that follows, and in part will become apparent to those skilled in the art upon examination of the following or can be learned by practice of the present disclosure.

DETAILED DESCRIPTION
[0029] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are some embodiments of the present disclosure, not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present disclosure.
[0030] Reference is made to Figure 1 and Figure 2 , Figure 1 A mine car transportation high-pressure spraying dust suppression system schematic diagram provided by the embodiment of the present disclosure, Figure 2The lifting pump and water pump connection schematic diagram is provided for the embodiment of the present disclosure. Since the dust mainly generated in the process of mining truck transportation is in the process of loading and unloading, according to the national environmental protection requirements, the tarpaulin is basically used to cover in the process of mining truck transportation, and the dust problem does not need to be considered in the transportation link. However, the tarpaulin must be opened in the process of loading and unloading, so the water pump 2 in the system provides power to the spraying assembly 3 to spray and reduce the dust of the truck box 5.
[0031] The system comprises a lifting pump 1, a water pump 2 and a spraying assembly 3. The lifting pump 1 is connected to the truck gearbox 61 through a power takeoff 4 and is used for lifting the box 5. One end of the lifting pump 1 is coaxially connected with a transmission shaft 11. The water pump 2 is coaxially connected to the lifting pump 1 through the transmission shaft 11. The spraying assembly 3 is connected to the water pump 2 and is used for spraying the box 5 of the truck.
[0032] In the embodiment, the engine 6 is connected with the gearbox 61. The lifting pump 1 is connected with the end of the gearbox 61 away from the engine 6. The transmission shaft 11 is located on the side of the lifting pump 1 away from the gearbox 61. The water pump 2 is connected with the end of the transmission shaft 11 away from the lifting pump 1. The engine 6 of the truck drives the lifting pump 1 to act through the gearbox 61. The lifting pump 1 drives the box 5 to rotate and unload. The power takeoff 4 of the truck is used as a switch for connecting the lifting pump 1 and the gearbox 61. The action of the box 5 of the truck is controlled by operating the lifting handle to control the action of the lifting pump 1. When the water pump 2 is used, only the power takeoff 4 switch of the vehicle cab self-contained gearbox 61 needs to be turned on to start. When the lifting pump 1 is used, the power takeoff 4 needs to be turned on and the lifting control handle needs to be operated at the same time. That is to say, on the basis of the original lifting pump 1, the water pump 2 is connected in series through the transmission shaft 11 and coaxially driven with the lifting pump 1. The double driving power is transmitted to the driving shaft through the power takeoff 4 of the gearbox 61, and the lifting pump 1 and the water pump 2 are driven at the same time.
[0033] It should be noted that when the water pump 2 needs to be started, only the gearbox 61 gear needs to be put into neutral, the power takeoff 4 switch is pressed, and the gear is re-engaged. It is worth noting that because the engine 6 has a high speed, the water pump 2 starts to work after the clutch pedal is released when the gear is directly engaged in 1, which is consistent with the operation of the lifting box 5. If there is no other operation in the process of loading and unloading, only the lifting control handle needs to be turned on in the process of unloading. At this time, the operation of the lifting box 5 is not affected, and the water spraying and dust reduction are just in time when the dust is large in the process of unloading. The operation is extremely simple.
[0034] In some embodiments, the spraying assembly 3 comprises a spraying water tank 31, a spraying pipe 32 and a spray head 33. The spraying water tank 31 is arranged at the bottom of the truck. The spraying pipe 32 is connected to the spraying water tank 31 and the water pump 2. The spraying pipe 32 is arranged around the truck chassis and the box 5. The spray head 33 is arranged on the spraying pipe 32.
[0035] In the embodiment, the spray pipe 32 connects the water pump 2 and the spray water tank 31, so that the water pump 2 pumps water from the spray water tank 31 to the spray head 33 after working. The spray pipe 32 is arranged around the side walls of the mine car chassis and the cargo box 5, so that the spray head 33 on the spray pipe 32 can reduce dust during loading and unloading of the cargo box 5.
[0036] Exemplarily, the spray water tank 31 has a spray opening for cooling the brake pad of the mine car. It can be understood that the spray water tank 31 also serves as a water tank for water cooling of the brake pad at the bottom of the mine car. Since the outlet pressure of the water pump 2 is large, it may cause damage to the pipeline, so an overflow valve 7 is installed at the spray opening and the outlet of the spray pipe 32, which returns water to the spray water tank 31 according to the set pressure.
[0037] Exemplarily, the spray head 33 is a high-pressure fan-shaped spray head 33. The connection mode between the spray head 33 and the spray pipe 32 adopts an internal thread rotary connection mode, and a 1 / 8-6510 (65° 2.0mm hole) spray head 33 is usually used. Due to the large water pressure, the high-pressure spray head 33 is 65°, and the water mist is fan-shaped, which can cover the entire cargo box 5.
[0038] Exemplarily, a filter screen is arranged in the spray water tank 31 at the pipe opening of the spray pipe 32. The pipeline arrangement usually adopts the following mode: water is introduced from the spray water tank 31, a general filter screen is installed, then the water passes through the water pump 2, the outlet is arranged along the chassis, and then extends to the top of the cargo box 5 through the tail of the cargo box 5, and then surrounds the cargo box 5 through the head of the cargo box 5, which can avoid affecting the pipeline when the cargo box 5 is lifted.
[0039] In some embodiments, the spray pipe 32 includes a chassis pipeline 321, a cargo box 5 pipeline 322, and a connecting hose 323 for connecting the chassis pipeline 321 and the cargo box 5 pipeline 322. The chassis pipeline 321 is a transparent hard pipeline. The connecting hose 323 is located at the hinged part of the cargo box 5 and the mine car. The cargo box 5 pipeline 322 is a metal pipeline, and the spray head 33 is arranged on the cargo box 5 pipeline 322.
[0040] In the embodiment, the chassis pipeline 321 surrounds the mine car chassis, and the chassis pipeline 321 and the cargo box 5 pipeline 322 are connected through the connecting hose 323 at the tail of the cargo box 5. The cargo box 5 pipeline 322 is located on both sides of the cargo box 5, and is curved and coiled along the bottom wall and the top wall of the cargo box 5, so that the spray head 33 on the cargo box 5 pipeline 322 can spray mist to the inside and around of the cargo box 5 to reduce dust.
[0041] It should be noted that the overflow valve 7 at the outlet of the water pump 2 and the ball valve 8 at the tail of the spray pipe 32 can overflow the high pressure generated in the system due to the sudden increase of the rotating speed of the engine 6, and return the water to the spray tank 31 according to the set pressure, so as to prevent the pipe from being burst; the ball valve of the spray pipe 32 is arranged at the tail of the spray pipe 32, and in the case that the spray tank 31 is not added with water in time, the pipe is easy to be filled with air. After the spray tank 31 is added with water again, the air in the pipe cannot be automatically discharged. At this time, the air needs to be manually discharged. A DN15 valve is arranged at the tail, so that the air can be directly discharged through the valve. In the case that the water pump 2 is in a vacuum state, water needs to be filled from the water outlet plug position, so that the water pump 2 can work normally again in the case that there is water.
[0042] Although the present disclosure is described in detail with reference to the foregoing embodiments, it should be understood that those of ordinary skill in the art can still make modifications to the technical solutions recorded in the foregoing embodiments, or make equivalent replacements to part of the technical features, and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present disclosure.
