Description

Technical Field

[0001] The invention relates to the technical field of coal mine electromechanical cooling, and in particular to a coal mine electromechanical cooling device. Background Art

[0002] Coal mine electromechanical equipment plays a vital role in coal mining operations. Their efficient and stable operation is the key to ensuring production safety and efficiency. However, due to the particularity of the coal mine operating environment, high temperature, high humidity and the presence of a large amount of dust pose a severe challenge to the performance and service life of coal mine electromechanical equipment. Therefore, it is particularly important to take scientific and effective cooling measures during the use of coal mine electromechanical equipment.

[0003] In order to effectively deal with the failure or performance degradation of coal mine electromechanical equipment caused by high temperature, the application of cooling equipment is indispensable. Cooling not only helps to keep the equipment running within a suitable temperature range, but also improves the overall stability and working efficiency of the equipment.

[0004] At present, in the field of electromechanical cooling in coal mines, the most commonly used cooling method is ventilation cooling. By installing high-power ventilation equipment, such as fans or ventilation duct systems, the air flow in the coal mine tunnels is accelerated, and the heat accumulated around the equipment is taken away, thereby achieving the purpose of cooling. However, the air in the coal mine environment often contains a large amount of dust. Although the direct use of ventilation cooling can bring a certain cooling effect, it will also be accompanied by the spread of a large amount of dust, which not only pollutes the external environment, but also may cause harm to the health of operators, and also increases the difficulty of subsequent cleaning work. The existing filter structure cannot be well combined with the existing ventilation equipment, and the existing filter structure is usually a simple one or several filter nets, with poor filtering effect and low filter net utilization. Summary of the invention

[0005] In order to solve the technical problems that a large amount of coal mine dust is discharged during ventilation and cooling projects of coal mine electromechanical equipment, the existing filtering structure cannot be well combined with the existing ventilation equipment, and the existing filtering structure is usually a simple one or several filter nets, with poor filtering effect and low filter net utilization rate, the present invention provides a cooling device for coal mine electromechanical equipment.

[0006] To achieve the above object, the technical solution adopted by the present invention is: A cooling device for coal mine electromechanical use, including a ventilation box, a fan is provided in an opening at one end of the ventilation box, the other end of the ventilation box is connected to one end of a guide pipe, the other end of the guide pipe is connected to a processing box, a vent is provided at one end of the processing box away from the guide pipe, a drainage component and a filter component are provided in the processing box, the drainage component is provided with a drainage air duct that repeatedly passes through the filter component, the drainage air duct is serpentine, and the drainage air duct is connected to the vent.

[0007] By adopting the above structural scheme, the ventilation box is placed on one side of the coal mine electromechanical equipment. After the movement is completed, the fan is started to draw the high-temperature air generated by the coal mine electromechanical equipment into the ventilation box. The high-temperature air passes through the ventilation box, the guide pipe and the processing box and is discharged from the vent to the outside, taking away the heat accumulated around the equipment, so as to achieve the effect of ventilation and cooling the coal mine electromechanical equipment. When the high-temperature air passes through the processing box, it passes through the filter assembly repeatedly under the guidance of the drainage assembly, fully filtering the dust, which can improve the filtering effect and the utilization rate of the filter belt.

[0008] As a preferred implementation method of a cooling device for coal mine electromechanical use, the filter assembly includes two mounting rollers, which are rotatably installed in a processing box, and the two mounting rollers are arranged in parallel, one of which is arranged close to the guide pipe, and the other is arranged close to the vent. A filter belt is wound around the two mounting rollers in an annular manner, and a plurality of filter holes are opened on the filter belt. A drive motor is installed outside the processing box, and the drive motor drives one of the mounting rollers to rotate; the drainage assembly includes a plurality of drainage plates, and all the drainage plates are arranged parallel to the axial direction of the mounting rollers; all the drainage plates are seamlessly connected to the inner wall of the processing box on both sides of the axial direction of the mounting rollers; one of the two sides of all the drainage plates perpendicular to the axial direction of the mounting rollers is seamlessly connected to the inner wall of the processing box, and the other side is provided with a through groove, and the filter belt passes through the through groove, and two adjacent drainage plates are staggered.

[0009] By adopting the above-mentioned structural scheme, the filter assembly and the drainage assembly cooperate with each other, so that the high-temperature gas can pass through the filter belt multiple times, filter the dust in the high-temperature gas and fully ensure the filtering effect. During the filtering process, the inner wall of the groove can scrape off the stubborn dust accumulated on the filter belt, ensuring the permeability of the filter belt, and facilitating the continuous and effective filtering and separation of dust during ventilation and cooling.

[0010] As a preferred implementation of a cooling device for coal mine electromechanical applications, the distance between the edge of the filter belt and the inner wall of the through slot is 1-2 mm.

[0011] The above structural solution is adopted to further facilitate the continuous and effective filtration and separation of dust during the ventilation and cooling process, thereby maintaining the permeability of the filter belt.

[0012] As a preferred implementation method of a cooling device for coal mine electromechanical equipment, two groups of separation components are installed in the processing box, each group of separation components includes a mounting rod, the mounting rod is arranged parallel to the mounting roller, a scraper is installed on the mounting rod, and the scraper abuts against the side wall of the filter belt; one group of separation components is installed on the outside of the filter belt, and the other group of separation components is installed in the annular space in the middle of the filter belt.

[0013] By adopting the above structural scheme, the scraper can scrape and separate the dust adsorbed on the inner and outer sides of the filter belt, ensuring the permeability of the filter belt and facilitating the continuous and effective filtration and separation of dust during ventilation and cooling.

[0014] As a preferred implementation method of a cooling device for coal mine electromechanical equipment, a pushing assembly is installed in a processing box, and the pushing assembly includes two mounting plates. The two mounting plates are arranged perpendicular to the filter belt, and the two mounting plates are respectively located on both sides of the filter belt. The two ends of the mounting rod are respectively installed on the two mounting plates, and the same side of the two mounting plates is connected to a strip plate. The length direction of the strip plate is parallel to the axial direction of the mounting roller. The strip plate is located on the outside of the filter belt, and an elastic assembly is connected between the strip plate and the inner wall of the processing box.

[0015] By adopting the above structural scheme, the elastic component can push the pushing component, and the pushing component further pushes the scraper to abut against the outer and inner sides of the filter belt. Through the abutment effect, the dust adsorbed on the filter belt is scraped and separated. The elastic component can ensure that the scraper continues to abut against the filter belt.

[0016] As a preferred implementation method of a cooling device for coal mine electromechanical equipment, the elastic component includes a support plate, which is parallel to the strip plate and located on the side of the strip plate away from the filter belt. A plurality of sleeves are vertically installed on the side of the support plate facing the strip plate, and a sliding rod is slidably connected in each sleeve. The end of the sliding rod away from the sleeve is connected to the strip plate, and a spring is provided on the outer periphery of the sleeve and the sliding rod, and the two ends of the spring are respectively connected to the strip plate and the support plate; the side of the support plate away from the strip plate is connected to the inner wall of the processing box.

[0017] By adopting the above structural solution, the strip plate is squeezed and pushed by the spring, and the movement of the strip plate is guided by the sleeve and the slide rod, so that the elastic component can elastically push the pushing component.

[0018] As a preferred implementation of a cooling device for coal mine electromechanical use, both ends of the mounting rod are elastically rotatably connected to two mounting plates.

[0019] With the above structural solution, when the scraper encounters hard particles, it can elastically rotate to avoid them, and restore its position after avoiding them, thus timely avoiding friction between the scraper and the hard particles and preventing the hard particles from scratching the filter belt.

[0020] As a preferred implementation of a cooling device for coal mine electromechanical use, the cross section of the scraper on the side abutting against the filter belt is triangular, with the tip of the triangle facing the filter belt.

[0021] By adopting the above structural solution, the shape of the scraper is convenient for scraping away dust.

[0022] As a preferred implementation of a cooling device for coal mine electromechanical equipment, the filter belt and the guide plate are arranged vertically.

[0023] The above structural solution is adopted to improve the utilization rate of the internal space of the processing box.

[0024] As a preferred implementation of a cooling device for coal mine electromechanical equipment, the outer diameter of the guide pipe at one end facing the ventilation box is greater than the outer diameter at one end facing the processing box.

[0025] By adopting the above structural solution, when the high-temperature air flows from the ventilation box into the processing box through the guide duct, the air flow speed will become faster, thereby improving the ventilation efficiency and further improving the cooling effect.

[0026] The beneficial effects of the present invention include: Place the ventilation box on one side of the coal mine electromechanical equipment. After the movement is completed, start the fan to draw the high-temperature air generated by the coal mine electromechanical equipment into the ventilation box. The high-temperature air passes through the ventilation box, guide pipe and processing box and is discharged from the vent to the outside, taking away the heat accumulated around the equipment, so as to achieve the effect of ventilation and cooling the coal mine electromechanical equipment. When the high-temperature air passes through the processing box, it passes through the filter component repeatedly under the guidance of the drainage component, fully filtering the dust, which can improve the filtering effect and the utilization rate of the filter belt.

[0030] Reference Figure 1-4 The present embodiment proposes a cooling device for coal mine electromechanical, including a ventilation box 101, a fan 104 is provided in an opening at one end of the ventilation box 101, the other end of the ventilation box 101 is connected to one end of a guide pipe 103, the other end of the guide pipe 103 is connected to a processing box 102, the outer diameter of the guide pipe 103 toward the ventilation box 101 is greater than the outer diameter toward the end of the processing box 102; a vent is provided at one end of the processing box 102 away from the guide pipe 103, a drainage component and a filter component are provided in the processing box 102, the drainage component is provided with a drainage air duct that repeatedly passes through the filter component, the drainage air duct is serpentine, and the drainage air duct is connected to the vent.

[0031] The filter assembly includes two installation rollers 202, which are rotatably installed in the processing box 102. The two installation rollers 202 are arranged in parallel, one of which is arranged close to the guide pipe 103, and the other is arranged close to the vent. A filter belt 201 is annularly wound on the two installation rollers 202, and a plurality of filter holes are opened on the filter belt 201. A driving motor 203 is installed outside the processing box 102, and the driving motor 203 drives one of the installation rollers 202 to rotate; the drainage assembly includes a plurality of drainage plates 301, all of which are arranged parallel to the axial direction of the installation rollers 202, and the filter belt 201 and the drainage plates 301 are arranged parallel to each other. Vertically arranged; all the guide plates 301 are seamlessly connected to the inner wall of the processing box 102 on both sides along the axial direction of the installation roller 202; one of the two sides of all the guide plates 301 perpendicular to the axial direction of the installation roller 202 is seamlessly connected to the inner wall of the processing box 102, and the other side is provided with a through groove 302, and the filter belt 201 passes through the through groove 302, and the distance between the edge of the filter belt 201 and the inner wall of the through groove 302 is 1-2mm, and two adjacent guide plates 301 are staggered, and the gaps between the guide plates 301 form guide air ducts, and the guide air ducts repeatedly pass through the filter belt 201, and because the filter belt 201 is annular, double-layer filtration is performed each time.

[0032] Two groups of separation components are installed in the processing box 102, and each group of separation components includes a mounting rod 401, which is arranged parallel to the mounting roller 202. A scraper 402 is installed on the mounting rod 401, and the scraper 402 abuts against the side wall of the filter belt 201. The cross-section of the scraper 402 facing the side abutting against the filter belt 201 is triangular, and the tip of the triangle faces the filter belt 201; one group of separation components is installed on the outside of the filter belt 201, and the other group of separation components is installed in the annular space in the middle of the filter belt 201. A pushing assembly is installed in the processing box 102, and the pushing assembly includes two mounting plates 501. The two mounting plates 501 are arranged perpendicular to the filter belt 201, and the two mounting plates 501 are respectively located on both sides of the filter belt 201. The two ends of the mounting rod 401 are elastically rotatably mounted on the two mounting plates 501, and the same side of the two mounting plates 501 is connected to the strip plate 502. The length direction of the strip plate 502 is parallel to the axial direction of the mounting roller 202. The strip plate 502 is located on the outside of the filter belt 201, and an elastic assembly is connected between the strip plate 502 and the inner wall of the processing box 102. The elastic component includes a support plate 601, which is parallel to the strip plate 502. The support plate 601 is located on the side of the strip plate 502 away from the filter belt 201. A plurality of sleeves 602 are vertically installed on the side of the support plate 601 facing the strip plate 502. A slide rod 603 is slidably connected in each sleeve 602. The end of the slide rod 603 away from the sleeve 602 is connected to the strip plate 502. A spring 604 is sleeved on the outer periphery of the sleeve 602 and the slide rod 603. The two ends of the spring 604 are respectively connected to the strip plate 502 and the support plate 601; the side of the support plate 601 away from the strip plate 502 is connected to the inner wall of the processing box 102.

[0033] The working principle of this embodiment is: Place the ventilation box 101 on one side of the coal mine electromechanical equipment. After the movement is completed, start the fan 104 to draw the high-temperature air generated by the coal mine electromechanical equipment into the ventilation box 101. The high-temperature air passes through the ventilation box 101, the guide pipe 103 and the processing box 102 and is discharged outward from the vent, taking away the heat accumulated around the equipment, thereby achieving the effect of ventilation and cooling the coal mine electromechanical equipment.

[0034] Since multiple guide plates 301 are fixed inside the processing box 102, and two adjacent guide plates 301 are located on both sides of the processing box 102 and are staggered, a serpentine guide air duct is formed between all the guide plates 301, and the filter belt 201 passes through all the guide plates 301 through the through groove 302. Therefore, when the high-temperature air passes through the guide air duct, it will pass through the filter belt 201 repeatedly to fully filter the dust, thereby improving the filtering effect and the utilization rate of the filter belt 201.

[0035] The filter belt 201 is driven by the driving motor 203 to rotate between the two mounting rollers 202, so that different positions of the filter belt 201 can be used for filtering, thereby improving the filtering effect of the filter belt 201. During the movement of the filter belt 201, thick dust accumulated on the surface of the filter belt 201 will rub against the inner wall of the through groove 302, thereby scraping off the thick dust and separating the dust from the filter belt 201. The inner wall of the through groove 302 can effectively separate the dust that has accumulated for a long time, is thick, and is agglomerated.

[0036] The push assembly makes the two scrapers 402 abut against the inner and outer sides of the filter belt 201. Through the abutment, the dust adsorbed on the filter belt 201 is scraped and separated, ensuring the permeability of the filter belt 201, and further facilitating the continuous and effective filtration and separation of dust during the ventilation and cooling process. The push assembly and the separation assembly can effectively separate the dust with a short accumulation time, thinness, softness, and small particles.

[0037] In this embodiment, since the outer diameter of the end of the guide duct 103 facing the ventilation box 101 is larger than the outer diameter of the end facing the processing box 102, when the high-temperature air flows from the ventilation box 101 into the processing box 102 through the guide duct 103, the air flow speed will become faster, thereby improving the ventilation efficiency and thus improving the cooling effect. At the same time, since the guide plate 301 further reduces the cross-sectional area, the air flow speed will be further accelerated in the processing box 102, thereby improving the filtering efficiency, ventilation efficiency and cooling effect.

[0038] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
