Description

Technical Field

[0001] This utility model relates to the field of jetting technology, specifically to a wet dust removal spiral feeding jetting machine. Background Technology

[0002] A spraying machine is a device that sprays materials such as paint, mortar, and plaster onto a target surface using high-pressure spraying. This can greatly improve construction efficiency and reduce the time and labor intensity of manual operation. Spraying machines are commonly used to spray building materials such as concrete and mortar for reinforcing structures and repairing walls.

[0003] Currently, spraying machines rely on manual mixing of the spraying material before adding it to the machine's hopper. This process not only results in uneven mixing but also generates a large amount of dust, increasing the workload for workers and seriously harming their physical and mental health. While dust-collecting spraying machines are available, they can only collect a portion of the dust and require regular replacement of the dust collector filter, failing to fundamentally solve the dust problem and increasing operating costs. Conventional spraying machines use double-layer hoppers without dust covers, and gaps exist between the upper and lower hoppers, generating dust during the feeding process that cannot be removed. Although atomizers have been installed above the hoppers to reduce dust, this creates a dirty and chaotic working environment near the spraying machine, and even leads to material caking in the hoppers, posing a risk of pipe blockage and significant safety hazards. Furthermore, the existing spraying machine's airflow system only has pressure gauges at the air inlet, preventing quantitative control of the pressure in the upper and lower airflow paths, which can easily cause pipe blockages during long-distance spraying. Summary of the Invention

[0004] This invention addresses the problems of existing spraying machines' ineffective dust removal and the inability to quantitatively control the pressure of the upper and lower air ducts by providing a wet dust removal spiral feeding spraying machine. This spraying machine uses a spiral feeding method, which facilitates feeding and ensures uniform mixing of the sprayed material. Simultaneously, the wet dust removal method effectively removes dust generated during the operation of the spraying machine, allowing the dust to be discharged after being moistened, thus improving the working environment. Furthermore, it enables quantitative control of the pressure in the upper and lower air ducts of the air system.

[0005] To achieve the above objectives, the technical solution of this utility model is: a wet dust-collecting spiral feeding jetting machine, comprising a chassis, a spiral feeder, and a track wheel assembly arranged at the bottom of the chassis. The chassis is equipped with a rotor jetting assembly, a ventilation mechanism, and a wet dust collection mechanism. The spiral feeder is inclined upwards on the chassis, and its discharge end corresponds to the rotor jetting assembly. A negative pressure dust collection hood is provided on the rotor jetting assembly. The track wheel assembly at the bottom of the chassis facilitates the movement of the jetting machine. The rotor jetting assembly achieves the effect of jetting the material. The ventilation mechanism provides compressed air to the rotor jetting assembly and the wet dust collection mechanism, providing power for the rotor jetting assembly to jet the material and for the wet dust collection mechanism to collect dust.

[0006] The airflow mechanism is connected to the rotor injection assembly and the wet dust removal mechanism; the wet dust removal mechanism includes a negative pressure circulation pipe, an air inlet assembly, and a spray assembly. Compressed air can be introduced into the negative pressure circulation pipe through the air inlet assembly, and negative pressure can be generated through the negative pressure circulation pipe to extract dust from the negative pressure dust removal hood. The spray assembly wets the extracted dust.

[0007] The negative pressure circulation duct includes a central pipe, a middle pipe, and an outer pipe arranged sequentially from the inside out. The air inlet assembly is mounted on the outer pipe. One end of the central pipe is connected to the negative pressure dust collector hood. One end of the middle pipe is connected to a reducer, which is connected to a spray assembly. Compressed air passes sequentially through the outer and middle pipes and is discharged through the reducer, thereby creating negative pressure in the central pipe to draw dust from inside the negative pressure dust collector hood.

The track wheel shaft is fixedly connected to the chassis, and track wheels are rotatably mounted on both ends of the track wheel shaft.

The ear plates are symmetrically arranged at the bottom of the chassis, and the support tubes are sleeved on the ear plates. The track wheels of the track wheel assembly facilitate the movement of the jetting machine. By assembling and disassembling the support tubes, the height of the feed end of the screw conveyor can be lowered or raised, thereby raising or lowering the discharge end of the screw conveyor, allowing the jetting machine to pass through low-lying spaces.

A discharge hole is provided on the panel, and the hydrocyclone is fixedly installed at the bottom of the panel and corresponds to the discharge hole. The power unit drives the rotor body to rotate. The rotation of the rotor body causes the material chamber of the rotor body to correspond sequentially with the discharge hole, so that the hydrocyclone can spray the injection material. The arc-shaped holes facilitate the injection material entering the material chamber of the rotor body.

[0011] Furthermore, the hopper seat is provided with multiple clamping seats arranged in a ring, and clamping grooves are formed on the outer side of the clamping seats; the top of the panel is provided with multiple pressing components corresponding to the clamping seats, each pressing component including a hinged seat, a pull rod, and a rubber spring.

The sealing plate located above is provided with strip-shaped holes and circular holes at the positions corresponding to the concave groove. Through the cooperation of the pull rod and the clamping seats, and under the action of the rubber spring, the hopper seat is pressed and fixed, improving the sealing effect between the rotor body, the hopper seat, and the panel; the air inlet channel can provide power for spraying the slurry material.

[0012] Furthermore, the airflow mechanism includes an inlet duct, a distribution duct, an upper duct, and a lower duct. The distribution duct is vertically mounted on the top of the chassis, and the inlet duct, upper duct, and lower duct are all connected to the distribution duct. The upper duct and lower duct are respectively connected to the air inlet channel and the cyclone separator. An external air compressor can be connected through the inlet duct to provide compressed air to the distribution duct.

The air intake hose can deliver compressed air from the air intake pipe to the outer layer pipe, providing power for the wet dust removal mechanism.

[0016] Furthermore, the spray assembly includes a curved pipe, an atomizing nozzle, and a dust removal hose. The two ends of the curved pipe are connected to the dust removal hose and a reducing pipe, respectively. A fixed sleeve is vertically installed on the curved pipe. The atomizing nozzle is disposed within the fixed sleeve and corresponds to the outlet of the curved pipe. A valve is connected to the atomizing nozzle via a transition joint. Water mist can be sprayed into the curved pipe through the atomizing nozzle to moisten the dust discharged through the curved pipe.

[0017] The beneficial effects of this utility model through the above technical solution are as follows:

[0018] This utility model has a reasonable structure and good performance. Compared with the traditional slurry feeding method of the spraying machine, it adds a spiral mixing feeding function, which not only facilitates feeding but also makes the sprayed material evenly mixed. At the same time, the wet dust removal method can effectively remove the dust generated during the operation of the spraying machine, so that the dust is discharged after being moistened, improving the working environment and protecting the physical and mental health of the operators. In addition, it can also quantitatively control the pressure of the upper and lower air passages of the air passage system to ensure the pressure of the upper and lower air passages of the air passage system, so as to avoid the phenomenon of pipe blockage during long-distance spraying of the spraying machine.

[0019] This invention achieves a spiral mixing and feeding effect by tilting the screw feeder upwards onto the chassis, positioning it above the rotor spraying assembly and ensuring uniform mixing of the sprayed material. Simultaneously, by disassembling and assembling the support pipe of the support assembly, the height of the screw feeder's feed end can be lowered or raised, thus raising or lowering the discharge end, facilitating the sprayer's passage through low-ceilinged spaces. Furthermore, the dust cover prevents dust from escaping during the screw feeder's feeding of the rotor spraying assembly, improving the working environment.

[0020] This utility model connects to an external air compressor via an air inlet pipe to provide compressed air to the air distribution pipe. The compressed air can be delivered to the air inlet channel and the cyclone separator through the upper and lower air pipes, thereby achieving the effect of spraying slurry material from the rotor spray assembly. Pressure gauge 2 and valve 5 are installed on both the upper and lower air pipes to achieve quantitative control of the compressed air pressure in the upper and lower air pipes of the air circuit mechanism.

[0021] This invention utilizes the air intake rib of the air intake assembly to deliver compressed air from the air intake duct to the outer duct, providing power for the wet dust removal mechanism. The compressed air passes sequentially through the outer and middle ducts and is discharged through the reducer, creating negative pressure in the central duct to extract dust from the negative pressure dust removal hood. Furthermore, water mist can be sprayed into the bend through the atomizing nozzle to moisten the dust discharged through the bend, preventing dust from escaping and improving the working environment.

There are three centering cylinders 4043, which ensure the stability of the middle tube 403 and the central tube 404. The central tube 404 is connected to the negative pressure dust collector hood 309 through the negative pressure outlet pipe 4041. Through the negative pressure generated by the negative pressure circulation pipe, the dust in the negative pressure dust collector hood 309 is discharged through the negative pressure outlet pipe 4041, the central tube 404, and the reducing pipe 405.

[0048] The air intake assembly 407 includes an air intake hose 4071, with valves 4072 and 5012 connected to its two ends respectively. The air intake hose 4071 is connected to the outer tube 401 and the air intake pipe 501 via valves 4072 and 5012 respectively. In this embodiment, the compressed air in the air intake pipe 501 can be transported to the outer tube 401 by the air intake hose 4071 to provide power for the wet dust removal mechanism; valves 4072 and 5012 are used to open and close the air intake hose 4071.

[0049] The spray assembly 406 includes a bend 4061, an atomizing nozzle 4063, and a dust removal hose 4065. The two ends of the bend 4061 are connected to the dust removal hose 4065 and the reducer 405, respectively. A fixing sleeve 4062 is vertically installed on the bend 4061. The atomizing nozzle 4063 is installed inside the fixing sleeve 4062 and corresponds to the outlet of the bend 4061. The atomizing nozzle 4063 is connected to a valve 4064 through a transition joint. In this embodiment, the bend 4061 is connected to the reducer 405 via a flange, and a sealing ring is installed at the flange connection. The fixing sleeve 6062 extends into the bend 4061 and is connected to the bend 4061. The valve 4064 can be connected to a water supply pipe, which is connected to an external water source. Water can be pumped through the water supply pipe to the atomizing nozzle 4063 by a water pump. The atomizing nozzle 4064 sprays water mist to wet the dust that is transported to the dust removal hose 4065 through the bend 4061.

[0050] The working principle of this utility model is as follows: When the jetting machine moves to the required working location and encounters a low space, the support pipe 1022 is inserted into the ear holes of the two ear plates. The support pipe 1022 supports the feeding end of the screw conveyor 2, raising the feeding end of the screw conveyor 2 and lowering the discharge end of the screw conveyor 2 to ensure that the jetting machine can pass through the low space. When the jetting machine moves to the working location, the support pipe 1022 is pulled out so that the feeding end of the screw conveyor 2 is parallel to the ground.

[0051] When the spraying machine is running, the screw feeder 2, air compressor and motor 3011 are turned on. The screw feeder 2 conveys the spraying material to the rotor spraying assembly 3. During the conveying process, the screw feeder 2 stirs the spraying material in a spiral. The spraying material enters the hopper of the rotor spraying assembly 3 through its discharge end and dust cover 202. The material in the hopper enters the material cavity of the rotor body 303 through the arc hole 3061. The motor 3011 and reducer 3012 drive the rotor body 303 to rotate. The material cavity of the rotor body 303 corresponds to the discharge hole in sequence.

[0052] Valve 4064, valve 4072, valve 5011, valve 5012, and valve 506 are all in the open state. Compressed air generated by the air compressor is delivered through the inlet pipe 501 to the distribution pipe 502, and then enters the upper pipe 503 and lower pipe 504 respectively. It then enters the inlet channel 3062 and the cyclone separator 307 respectively. Through the inlet channel 3062, the compressed air is delivered to the concave groove, and then through the strip hole 3051 and... The circular hole 3052 enters the material chamber of the rotor body 303, so that the sprayed material enters the hydrocyclone 307 and is then sprayed out through the hydrocyclone 307, providing power for the spraying of the sprayed material. During this process, two pressure gauges 505 can monitor the compressed air pressure in the upper air duct 503 and the lower air duct 504 respectively, so as to achieve the effect of quantitative control of the compressed air pressure in the upper air duct 503 and the lower air duct 504 of the air circuit mechanism, and avoid the phenomenon of pipe blockage during long-distance spraying of the spraying machine.

[0053] Compressed air is also delivered to the outer tube 401 through the inlet hose 4071, and then through the middle tube 403 and the reducer 405 to generate negative pressure, so that the dust in the negative pressure dust collector hood 309 is discharged sequentially through the negative pressure outlet pipe 4041, the central pipe 404 and the reducer 405; water is pumped to the atomizing nozzle 4063 through the water supply pipe by the water pump, and the atomizing nozzle 4064 sprays water mist to wet the dust delivered to the dust collector hose 4065 through the bend pipe 4061, and then the wetted dust is discharged through the dust collector hose 4065.

[0054] The embodiments described above are merely preferred embodiments of the utility model and are not intended to limit the scope of the utility model. Therefore, all equivalent changes or modifications made to the technical solutions described in the scope of the utility model patent application should be included within the scope of the utility model patent application.
