Description

Technical Field

[0001] This invention relates to the field of dust suppression technology, and in particular to a dust suppression spray system. Background Technology

[0002] In dusty environments such as mines, construction sites, coal yards, and material yards, spraying is commonly used to suppress dust. Spray dust suppression systems use high-pressure water pumps to pressurize water, which is then sprayed through atomizing nozzles to create a fine water mist. This water mist combines with airborne dust particles and causes them to settle, thus reducing the dust concentration on site. To ensure effective dust suppression, spray systems need to operate continuously for extended periods, requiring a large water consumption. The water source is typically well water, river water, or on-site circulating water.

[0003] Existing dust suppression spray systems typically include a water tank, a high-pressure water pump, water pipes, and atomizing nozzles. Water from an external source enters the water tank, is pressurized by the high-pressure water pump, and then transported through the water pipes to the atomizing nozzles for spraying. To prevent impurities in the water from clogging the atomizing nozzles, filters or filter cartridges are usually installed in the water path to filter the water entering the nozzles.

[0004] The nozzle diameter of atomizing nozzles is small, typically only tens to hundreds of micrometers. However, the water source inevitably contains particulate impurities such as silt, scale fragments, etc. Some of these impurity particles are close to or even larger than the nozzle diameter. These particles are easily trapped at the nozzle as the water flows through it and accumulate, eventually clogging the nozzle and causing a decrease in spray volume or even no spray at all. Existing filter screens or filter cartridges have relatively fixed filtration accuracy and filtration area. Low filtration accuracy makes it difficult to intercept fine particles, while high filtration accuracy results in limited filtration area and rapid impurity accumulation, requiring frequent shutdowns for replacement. Furthermore, existing filtration devices are mostly installed inside the water tank or pipelines, requiring disassembly of the water tank or pipelines for replacement, which is inconvenient and makes it difficult to balance filtration efficiency and maintenance convenience. This makes it impossible to continuously and stably intercept impurities, and the atomizing nozzles are still prone to clogging. Summary of the Invention

[0005] In view of the above-mentioned prior art, the present invention provides a dust suppression spray system to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the technical solution of this invention is implemented as follows: A dust suppression spray system includes a water tank, a high-pressure water pump, water pipes, and atomizing nozzles. The water tank is equipped with a horizontal partition that divides the water tank into an upper chamber and a lower chamber. The horizontal partition is equipped with several vertical plates, and the side walls of the vertical plates are provided with grooves that communicate with the lower chamber. A filter assembly is provided in the grooves. The upper chamber is connected to an external water source, and the lower chamber is equipped with the high-pressure water pump. The high-pressure water pump is connected to the atomizing nozzles through the water pipes.

[0007] Furthermore, the filter assembly includes a frame, a coarse filter unit, and a fine filter unit. Both the coarse filter unit and the fine filter unit are sealed to the perimeter of the frame. The frame is inserted into the groove, and the edge of the frame is sealed to the edge of the groove.

[0008] Furthermore, the coarse filtration unit is a stainless steel wire mesh filter basket. The mesh size is 80-100 mesh, and the filtration accuracy is approximately 150-180 μm.

[0009] Furthermore, the fine filtration unit is a PP cotton filter element or a pleated filter element.

[0010] Furthermore, the bottom of the groove is provided with a stop bar, which is flush with the surface of the vertical plate. The surface of the vertical plate is provided with a sealing ring, the bottom of which passes through the stop bar. The horizontal partition is provided with a trapezoidal slot, the inclined surface of which is located on the side away from the groove. The frame is inserted into the trapezoidal slot, and the top of the frame is provided with a slanted bolt, which is connected to the vertical plate.

[0011] Furthermore, the groove is provided with a plurality of vertical support bars, which are spaced apart and form a water flow channel between them.

[0012] Furthermore, a support mesh is provided between the support bar and the filter assembly.

[0013] Furthermore, the support mesh is a metal mesh with a mesh count greater than 100.

[0014] Furthermore, the vertical partition has grooves on both sides, and the distance between the filter assembly of the vertical partition and the filter assembly of another adjacent vertical partition is 0.5 to 2.0 cm.

[0015] Furthermore, the water pipe is equipped with an ion exchange softening tank.

[0016] The beneficial effects of this invention are as follows: Because the water tank is divided into an upper and lower chamber by a horizontal partition, water flows from the upper chamber through a filter assembly in a groove before entering the lower chamber. It is then pumped out by a high-pressure water pump and transported through a water pipe to the atomizing nozzle for spraying. Impurities in the water are intercepted by the filter assembly before entering the lower chamber, preventing them from entering the nozzle orifice and effectively preventing clogging, thus ensuring continuous and stable spraying. Simultaneously, filter assemblies are installed in grooves on several vertical plates, and these assemblies are connected in parallel, allowing water to pass through multiple assemblies simultaneously into the lower chamber, improving filtration efficiency. The filter assemblies are conveniently located within the grooves of the vertical plates, allowing for easy installation or replacement by opening the top of the water tank.

[0017] In addition, the water pipe is equipped with an ion exchange softening tank, which exchanges calcium and magnesium ions in the water for sodium ions, softens the water quality, reduces the deposition of scale on the inner walls of the water pipe and nozzle, further prevents the nozzle from being blocked by scale, and extends the service life of the atomizing nozzle.

[0020] It should also be noted that when an element is referred to as being "fixed to" another element, it can be directly attached to the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "inner," "outer," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0021] Please refer to the attached document. Figures 1 to 3This application provides a dust suppression spray system, including a water tank 1, a high-pressure water pump 17, a water pipe 18, and an atomizing nozzle 19. The water tank 1 is provided with a horizontal partition 2, which divides the water tank 1 into an upper cavity 3 and a lower cavity 4. The horizontal partition 2 is provided with a plurality of vertical plates 5. The side wall of the vertical plate 5 is provided with a groove 6 communicating with the lower cavity 4. A filter assembly 7 is provided in the groove 6. The upper cavity 3 is connected to an external water source. The lower cavity 4 is provided with the high-pressure water pump 17, which is connected to the atomizing nozzle 19 through the water pipe 18.

[0022] Water from an external source enters the upper chamber 3, which acts as a reservoir and buffer, ensuring a stable flow of water into the filter assembly 7. The water in the upper chamber 3 is filtered by the filter assembly 7 within the groove 6 before entering the groove 6 and then flowing into the lower chamber 4. Impurities in the water are intercepted by the filter assembly 7 before entering the groove 6, allowing only the filtered, clean water to enter the lower chamber 4. The clean water in the lower chamber 4 is pumped out and pressurized by the high-pressure water pump 17, then transported through the water pipe 18 to the atomizing nozzle 19. The atomizing nozzle 19 atomizes the pressurized water, creating a fine mist. This mist combines with and settles dust particles in the air, reducing the dust concentration on site. Because the water has already been filtered by the filter assembly 7 before entering the high-pressure water pump 17 and the atomizing nozzle 19, impurities do not enter the nozzle orifice with the water, preventing clogging and ensuring continuous and stable spraying. Furthermore, since the horizontal partition 2 is equipped with several vertical plates 5, and each vertical plate 5 has a filter assembly 7 in its groove 6, and these filter assemblies 7 are arranged in parallel and are all connected to the lower cavity 4, water can pass through multiple filter assemblies 7 simultaneously into the lower cavity 4, increasing the amount of water filtered per unit time and improving filtration efficiency. When one of the filter assemblies 7 is blocked by impurities, water can still pass through the remaining filter assemblies 7 into the lower cavity 4, without affecting the continuous water supply of the spray system. In addition, since the filter assembly 7 is located in the groove 6 of the vertical plate 5, the filter assembly 7 can be installed or replaced from the vertical plate 5 by opening the top of the water tank 1, without disassembling the water tank 1, making maintenance convenient.

[0023] Optionally, the high-pressure water pump 17 is a commercially available high-pressure plunger pump, and the atomizing nozzle 19 is a commercially available fan-shaped atomizing nozzle 19. Both of these are conventionally purchased parts in the field, and their specific models are selected according to the spray pressure and flow requirements.

[0024] Specifically, the filter assembly 7 includes a frame 8, a coarse filter unit 9, and a fine filter unit 10. Both the coarse filter unit 9 and the fine filter unit 10 are sealed to the perimeter of the frame 8. The frame 8 is inserted into the groove 6, and the edge of the frame 8 is sealed to the edge of the groove 6. Water passes through the coarse filter unit 9 and the fine filter unit 10 sequentially before entering the groove 6. The coarse filter unit 9 first intercepts large particles, and the fine filter unit 10 then intercepts fine particles. This staged filtration improves the interception effect of impurities and prevents large particles from impacting the fine filter unit 10 and shortening its service life. The insertion of the frame 8 into the groove 6, with its edge sealed to the edge of the groove 6, ensures that water can only pass through the coarse filter unit 9 and the fine filter unit 10 to enter the groove 6, and cannot bypass the filter assembly 7 through the gap between the frame 8 and the groove 6 to directly enter the groove 6, guaranteeing that all water entering the lower cavity 4 is filtered.

[0025] Specifically, the coarse filtration unit 9 is a stainless steel wire mesh filter basket. The mesh size is 80-100 mesh, and the filtration accuracy is approximately 150-180μm. The stainless steel wire mesh filter basket is high in strength and corrosion-resistant. The mesh size of 80 to 100 mesh corresponds to a filtration accuracy of 150 to 180μm, which can intercept large particles of impurities such as silt, scale fragments, etc., protecting the fine filtration unit 10 and preventing large particles of impurities from impacting and clogging the fine filtration unit 10.

[0026] Specifically, the fine filtration unit 10 is a PP cotton filter element or a pleated filter element. The filtration accuracy is 5~10μm. The PP cotton filter element relies on the gaps between the fibers to deeply adsorb fine particles, while the pleated filter element relies on the pleats to increase the filtration area. Both have high throughput, long service life, and a filtration accuracy of 5 to 10μm. They can intercept the fine particles remaining after passing through the coarse filtration unit 9, further purifying the water and ensuring that the water entering the high-pressure water pump 17 and the atomizing nozzle 19 is clean, preventing the nozzle from being blocked by fine particles.

[0027] Specifically, the bottom of the groove 6 is provided with a stop bar 11, which is flush with the surface of the vertical plate 5. A sealing ring 12 is provided on the surface of the vertical plate 5, with its bottom passing through the stop bar 11. The horizontal partition 2 is provided with a trapezoidal slot 13, the inclined surface of which is located away from the groove 6. The frame 8 is inserted into the trapezoidal slot 13, and a slanted bolt 14 is provided at the top of the frame 8, connecting to the vertical plate 5. After the frame 8 is inserted into the trapezoidal slot 13, the inclined surface of the slot 13 is located away from the groove 6. Under the guiding action of the inclined surface, the frame 8 is pressed tightly against the vertical plate 5, ensuring a tight fit between the frame 8 and the surface of the vertical plate 5. The slanted bolt 14 connects to the vertical plate 5 from the top of the frame 8. Tightening the slanted bolt 14 generates a downward pulling force on the frame 8, further tightening the frame 8 against the vertical plate 5. The sealing ring 12 is set on the surface of the vertical plate 5, and its bottom is attached to the baffle 11. The baffle 11 limits the lower end of the sealing ring 12, so that the sealing ring 12 is attached to the frame 8 during use, thereby forming a continuous and effective seal on the frame 8 and preventing water from passing through the bottom edge of the frame 8 and bypassing the filter assembly 7.

[0028] Specifically, the groove 6 is provided with a plurality of vertical support bars 15, which are spaced apart and form water flow channels between them. The support bars 15 support the filter assembly 7, keeping it stable under water pressure. The gaps between adjacent support bars 15 form water flow channels. After passing through the filter assembly 7, the water flows down into the lower cavity 4 through the water flow channels between the support bars 15, ensuring that the filtered water is discharged smoothly and does not stagnate in the groove 6.

[0029] Specifically, a support mesh 16 is provided between the support bar 15 and the filter assembly 7. The support mesh 16 is located between the support bar 15 and the filter assembly 7, and evenly transmits the water pressure borne by the filter assembly 7 to the support bar 15, thereby improving the pressure resistance of the filter assembly 7 and preventing the filter assembly 7 from deforming and being damaged under the action of water pressure.

[0030] Specifically, the support net 16 is a metal mesh with a mesh count greater than 100. The metal mesh has a high supporting capacity, can withstand significant water pressure, and has good permeability when the mesh count is greater than 100, allowing filtered water to quickly pass through the support net 16 without affecting the smooth discharge of water.

[0031] Specifically, the vertical partition has grooves 6 on both sides, and the distance between the filter assembly 7 of the vertical partition and the filter assembly 7 of another adjacent vertical partition is 0.5 to 2.0 cm. The distance between the two filter assemblies 7 forms a water flow channel, through which the filtered water flows into the lower cavity 4. Due to the vertical plate 5, multiple filter assemblies 7 can be arranged side by side in the horizontal direction inside the water tank 1, improving the utilization rate of the internal space of the water tank 1, obtaining a larger filtration area within the same volume of water tank 1, and reducing the size of the equipment. The spacing is controlled at 0.5 to 2.0 cm to ensure that the water flow channel has sufficient flow capacity while avoiding excessive spacing that would waste internal space of the water tank 1.

[0032] Specifically, the water pipe 18 is equipped with an ion exchange softening tank 20. The ion exchange softening tank 20 is filled with sodium-type resin, which exchanges calcium and magnesium ions in the water with sodium ions, softens the water quality, reduces the scale formation of calcium and magnesium ions on the inner walls of the water pipe 18 and the atomizing nozzle 19, further prevents scale from clogging the nozzles, and extends the service life of the atomizing nozzle 19.

[0033] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. The scope of protection of the present invention should be determined by the scope of the claims.
