Description

Technical Field

[0001] The invention relates to the technical field of mining equipment, and in particular to a conveyor belt for mining. Background Art

[0002] In the process of coal mining, it is generally necessary to use a conveyor belt to transport the mined coal. However, the conveyor belts in the related technology produce a lot of dust during the mining process, which causes the mining environment to be in a state of high dust density for a long time, which not only harms the environment, but also easily affects the health of the miners, and the observation distance is affected, which is not conducive to mining for the miners. In addition, during the continuous operation of the conveyor belt in the coal mine, the conveyor belt is loaded with a large load, resulting in a relatively high surface temperature of the conveyor belt. The high surface temperature of the conveyor belt makes it easy for coal to adhere to the surface of the conveyor belt, resulting in the accumulation of coal on the surface of the conveyor belt for a long time, and the staff need to clean the coal on the surface of the conveyor belt, which is time-consuming and labor-intensive, and has great limitations. Summary of the invention

[0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent.

DETAILED DESCRIPTION

[0023] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] According to the mining conveyor belt of the embodiment of the present invention, the mining conveyor belt includes a conveyor belt body, a cooling mechanism 2, a dust removal mechanism 3 and a liquid replenishing mechanism. The conveyor belt body includes a driving motor and a frame 1. The conveyor belt surrounds the frame 1. The driving motor is connected to the frame 1 and is connected to the conveyor belt transmission. The cooling mechanism 2 is located in the frame 1. The cooling mechanism 2 includes a cooling box 201 and an exhaust member 202. A heat dissipation pipe 203 is arranged in the cooling box 201 to dissipate heat in the cooling box 201. The exhaust member 202 is connected to the cooling box 201. It is generally used to spray cold air on the surface of the conveyor belt. The dust removal mechanism 3 is located in the frame 1. The dust removal mechanism 3 includes a dust removal box 301 and a dust suction shell 302. The dust suction shell 302 is connected to the dust removal box 301 to absorb dust into the dust removal shell. A plurality of spray parts 305 are arranged on the dust removal shell to form water mist to settle dust. The liquid replenishment mechanism includes a water injection pipe 4 and a drainage pipe 6. The water injection pipe 4 and the drainage pipe 6 are generally connected to the cooling box 201 and the dust removal box 301 to realize the liquid circulation in the cooling box 201 and the dust removal box 301. The cooling box 201 is arranged on both sides of the dust removal box 301, and there can be two cooling boxes 201. The heat dissipation pipe 203 can receive water from the water injection pipe 4 to cool the cooling box 201, and can also be connected to other cooling media to cool the cooling box 201. The heat dissipation pipe 203 adopts a heat dissipation copper pipe, which has good thermal conductivity. The heat dissipation copper pipe then transfers the heat to the surrounding environment, thereby reducing the temperature of the water in the cooling box 201. The copper pipe is arranged inside the cooling box 201, and one end of the copper pipe extends to the outside of the cooling box 201 for easy heat dissipation. The optional fin-type or spiral copper pipe structure increases the heat dissipation surface area of ​​the copper pipe and improves the cooling effect.

[0025] The mining conveyor belt according to the embodiment of the present invention has the advantages of low conveyor belt surface temperature and less dust adhesion.

[0026] In some embodiments, a support plate 205 and a connecting pipe 204 are provided in the cooling box 201. The support plate 205 is connected to the inner wall of the cooling box 201 and the heat dissipation pipe 203 to fix the heat dissipation pipe 203. One end of the connecting pipe 204 is connected to the exhaust component 202, and the other end of the connecting pipe 204 is connected to the output end of the air pump 206. The air pump 206 is used to supply air to the exhaust component 202.

[0027] Specifically, the support plate 205 supports and fixes the heat pipe 203, the connecting pipe 204 cooperates with the air pump 206 to extract the cold air in the cooling box 201, and the exhaust part 202 sprays the cold air on the surface of the conveyor belt to cool the conveyor belt. Optionally, the support plate 205 can be a grid plate or a perforated plate with strip holes, which increases the heat exchange area while fixing the heat pipe 203. The structural design of the support plate 205 and the connecting pipe 204 can ensure the stable operation of the heat pipe 203 and prevent damage caused by vibration. At the same time, the connecting pipe 204 ensures that the cold air output by the air pump 206 can be effectively transmitted to the exhaust part 202, thereby improving the cooling efficiency. The bottom of the exhaust part 202 is fixedly connected to the cooling box 201 through two stabilizing plates 7. The stabilizing plates 7 play a stabilizing supporting role for the exhaust part 202 and also change the working height of the exhaust part 202. The working height of the exhaust part 202 can be adjusted by changing the thickness of the stabilizing plates 7 to adapt to the working requirements of different conveyor belts.

[0028] In some embodiments, the heat dissipation pipe 203 is bent multiple times on the surface of the support plate 205 to increase the length of the heat dissipation pipe 203 in the cooling box 201 .

[0029] Specifically, the bending design of the heat dissipation pipe 203 is serpentine or wavy to maximize the heat dissipation area, and the bending design facilitates the installation of more heat dissipation pipes 203 in a limited space. The bending design increases the effective length of the heat dissipation pipe 203 in the cooling box 201, improves the heat dissipation efficiency, and helps the conveyor belt to maintain a low temperature after a long period of operation.

[0030] In some embodiments, an observation panel 5 is provided on the side of the cooling box 201 for observing the interior of the cooling box 201 .

[0031] Specifically, the observation panel 5 is made of transparent material, such as tempered glass or impact-resistant plastic, and is easy to open or disassemble quickly for internal inspection and maintenance. The observation panel 5 enables the operator to intuitively monitor the internal conditions of the cooling box 201, discover and deal with potential problems in a timely manner, and ensure the continuous and stable operation of the conveyor belt.

[0032] In some embodiments, the water injection pipe 4 is connected to the top of the cooling box 201 and the top of the dust removal box 301 respectively, and the drainage pipe 6 is connected to the side of the cooling box 201 and the side of the dust removal box 301.

[0033] Specifically, the water injection pipe 4 and the drain pipe 6 can be equipped with a filtering device to prevent impurities from entering the cooling box 201. This design realizes the circulation of liquid between the cooling box 201 and the dust removal box 301, ensures the heat dissipation and dust removal efficiency, and discharges waste water through the drain pipe 6 to keep the system clean.

[0034] In some embodiments, the exhaust member 202 is located at the top of the cooling box 201 , and the exhaust member 202 is connected to the cooling box 201 through a stabilizing plate 7 .

[0035] Specifically, the exhaust member 202 is a porous structure to ensure that the cold air is evenly sprayed onto the surface of the conveyor belt. The exhaust member 202 can be a rectangular member with multiple exhaust holes evenly distributed on the surface of the rectangular member. The exhaust member 202 located at the top can ensure that the cold air covers a wider range of the conveyor belt and improve the cooling uniformity.

[0036] In some embodiments, the dust collection shell 302 is located at the top of the dust collection box 301, and the dust collection box 301 has a dust collection chamber. A cleaning box 8 is slidably arranged in the dust collection chamber. The cleaning box 8 is used to collect dust from the dust collection shell 302, and multiple spray parts 305 are located in the dust collection chamber.

[0037] Specifically, the bottom of the dust-falling chamber is smooth to reduce dust accumulation. A slide rail is provided on the dust-falling chamber of the dust-removing box 301, and a pulley is provided at the bottom of the cleaning box 8. The pulley slides along the slide rail so that the cleaning box 8 is slidably connected with the dust-removing box 301, which facilitates the movement of the cleaning box 8. The dust in the dust-falling chamber is treated with water mist and settles in the cleaning box 8. The cleaning box 8 is taken out regularly to clean the settled dust, which is convenient for operation. The design of the cleaning box 8 facilitates the regular cleaning of the collected dust and maintains the continuous and efficient operation of the dust removal system.

[0038] In some embodiments, a water pump 304 is provided on the dust removal box 301, and the water pump 304 extracts water from the dust removal box 301 through a pipeline, and the water pump 304 is connected to the spray member 305 through a pipeline. A vacuum pump 303 is provided on the dust removal box 301, and the vacuum pump 303 is connected to the dust collection housing 302 through a pipeline to provide negative pressure for the dust collection housing 302.

[0039] Specifically, the vacuum pump 303 and the water pump 304 work together to settle dust by spraying and absorb dust by negative pressure, which greatly improves the dust removal efficiency and reduces environmental pollution. The water pump 304 extracts water from the dust removal box 301 and sprays it through the spray element 305 to form water mist. The water mist combines with the dust to settle the dust. The vacuum pump 303 provides negative pressure for the dust collection shell 302 to absorb external dust into the dust box of the dust removal box 301. The vacuum pump 303 is a reciprocating vacuum pump 303, and there can be three of them. There can be two water pumps 304.

[0040] In some embodiments, the liquid replenishing mechanism further includes a liquid level detector, which is respectively located in the cooling box 201 and the dust removal box 301 to detect the liquid level heights of the cooling box 201 and the dust removal box 301 .

[0041] Specifically, the liquid level detector can use a liquid sensor such as a magnetic float or a resistance liquid level sensor to detect the liquid level height in the dust removal box 301 and the cooling box 201, control the liquid replenishment speed of the liquid replenishment mechanism, and avoid equipment damage caused by excessively high or low liquid levels.
