Description

Technical Field

[0001] This utility model relates to the technical field of dust humidifiers, specifically to a dust humidifier for concrete station sites. Background Technology

[0002] A concrete mixing plant, also known as a concrete batching plant, mainly consists of five major systems: a mixing host, a material weighing system, a material conveying system, a material storage system, and a control system, as well as other auxiliary facilities. Dust humidifying mixers are essential equipment for reducing pollution in places where various dusty particulate materials are produced. Therefore, when using mixers for mixing operations, in order to avoid the spread of dust and thus damage to the environment and processing personnel, people usually humidify the dust particles to a certain extent during the mixing operation.

[0003] Existing dust humidifiers used in concrete plant sites do not have a shielding structure at the feeding end, allowing dust to easily escape from the feeding end during processing, resulting in resource waste. In addition, the spraying mechanism and the humidifier are integrated into one structure, making it inconvenient to maintain the parts inside the humidifier when maintenance is required after dust processing, thus affecting maintenance efficiency and quality. Furthermore, the installation efficiency is low and the limitations are significant. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a dust humidifier for concrete station sites to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] A dust humidifier for concrete batching plants includes a humidifier body and a support plate. One end of the humidifier body has a feed inlet. The support plate is welded to one end of the humidifier body. The top of the support plate has a discharge trough and a sliding groove, and several positioning rods are fixedly installed thereon. A support frame is fixedly installed on the top of the discharge trough, and a U-shaped frame is fixedly installed on the top of the support frame. Limit grooves are formed on both sides of the inner wall of the U-shaped frame, and limit rods are fixedly installed in the limit grooves. Two limit rods are equipped with shielding components and compression springs. The shielding components include baffles that can slide on the inner wall of the U-shaped frame and deform the compression springs. Mounting seats are fitted on the outer walls of the positioning rods. A sprayer is mounted on the top of the mounting seats. A clamping mechanism is mounted on the top of the support plate. The clamping mechanism includes a bidirectional screw and two clamping plates. The bidirectional screw can drive the two clamping plates to rotate and clamp the top two sides of the mounting seats.

[0006] Preferably, the shielding assembly further includes a sliding frame, the baffle is fixedly connected to the sliding frame and slidably sleeved on the two limiting rods, one end of the compression spring is connected to the baffle and the other end is connected to the inner wall of the limiting groove.

[0007] Preferably, a handle is fixedly installed on the top of the baffle.

[0008] Preferably, the clamping mechanism further includes several fixed seats and two rotating shafts. The fixed seats are all fixedly installed on the top of the bearing plate, and the two rotating shafts are rotatably connected to the fixed seats respectively. The two clamping plates are respectively fixedly sleeved on the two rotating shafts.

[0009] Preferably, the clamping mechanism further includes two sliders, two racks, and two gears. The two gears are fixedly connected to the two rotating shafts respectively. The two sliders are threaded onto the bidirectional lead screw and slide in cooperation with the inner wall of the groove. The two racks are fixedly connected to the two sliders respectively and mesh with the two gears respectively. When the bidirectional lead screw rotates, it drives the two gears to move relative to each other.

[0010] Preferably, the clamping mechanism further includes a motor, the bidirectional lead screw is rotatably connected to the bearing plate, and one end is fixedly connected to the output end of the motor.

[0011] Preferably, a fixing frame is fixedly installed at one end of the support plate, and the motor is fixedly installed at one end of the fixing frame.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0013] 1. This utility model provides a dust humidifier for concrete plant sites. Through the cooperation of the U-shaped frame, limiting groove, limiting rod, compression spring, shielding component and feeding trough, the sliding frame drives the baffle to slide horizontally within the U-shaped frame and compress the compression spring. Thus, after the feeding is completed and the handle is released, the baffle will automatically reset to shield the feeding trough. This not only reduces the difficulty of operation, but also reduces the probability of dust being wasted outside the humidifier body, improves the dust utilization rate, saves resources, and has strong applicability.

[0014] 2. This utility model provides a dust humidifier for concrete station sites. Through the cooperation of a motor, a two-way lead screw, a slider, a rack, a gear, a rotating shaft, a pressure plate, a mounting base, a sprayer, and a positioning rod, the positioning rod initially positions the mounting base. After the motor operates, it drives two pressure plates to press against the top two sides of the mounting base, which can quickly lock and install the mounting base, thereby reducing the difficulty of installing and disassembling the sprayer and the mounting base. After the sprayer is removed, it can be more comprehensively maintained as a whole, improving the maintenance quality. Attached Figure Description

[0023] To make the technical means, creative features, objectives, and effects of this utility model easier to understand, the following describes this utility model in conjunction with specific embodiments:

[0024] like Figure 1-6As shown, this utility model provides a dust humidifier for concrete station sites, including a humidifier body 1 and a support plate 2. One end of the humidifier body 1 is provided with a feed inlet 100. The support plate 2 is welded to one end of the humidifier body 1. A discharge trough 201 and a sliding groove 203 are provided on the top of the support plate 2, and several positioning rods 202 are fixedly installed thereon. A support frame 3 is fixedly installed on the top of the discharge trough 201, and a U-shaped frame 4 is fixedly installed on the top of the support frame 3. Limiting grooves 401 are provided on both sides of the inner wall of the U-shaped frame 4. Limiting rods 402 are fixedly installed in the limiting grooves 401. A shielding assembly 5 is provided on the two limiting rods 402, and a compression spring 403 is sleeved on each of them. The shielding assembly 5 includes a baffle 502. 2 can slide on the inner wall of the U-shaped frame 4 and deform the compression spring 403. The outer wall of several positioning rods 202 is fitted with mounting base 6. The top of the mounting base 6 is equipped with a sprayer 7. The top of the bearing plate 2 is equipped with a pressing mechanism 8. The pressing mechanism 8 includes a two-way screw 802 and two pressing plates 807. The two-way screw 802 can drive the two pressing plates 807 to rotate and press the top two sides of the mounting base 6. The shielding assembly 5 also includes a sliding frame 501. The baffle 502 is fixedly connected to the sliding frame 501 and is slidably fitted on the two limiting rods 402. One end of the compression spring 403 is connected to the baffle 502 and the other end is connected to the inner wall of the limiting groove 401. The top of the baffle 502 is fixedly installed with a handle 503.

[0025] First, connect the water inlet of the sprayer 7 to the water supply equipment, and then connect the water supply equipment and the sprayer 7 to the control module. Then, remotely start the sprayer 7 and the water supply equipment through the control module. When pouring in the dust, the operator holds the handle 503 and pushes the sliding frame 501 and the baffle 502 horizontally through the handle 503. At this time, the sliding frame 501 slides on the outer wall of the two limit rods 402, causing the compression spring 403 to deform until the baffle 502 no longer blocks the feeding trough 201. Then, the dust is poured into the humidifier body 1 through the feeding trough 201. Then, start the humidifier body 1 and the sprayer 7, spraying water while stirring the dust to perform humidification. Through the elastic potential energy of the compression spring 403, the feeding trough 201 can be quickly sealed after feeding, reducing the probability of dust being discharged from the feeding end 100, improving the dust utilization rate, and reducing air pollution. It has strong applicability and low operation difficulty, does not require manual reset by the operator, and improves work efficiency.

[0026] like Figure 4 and Figure 6As shown, in one embodiment, the clamping mechanism 8 further includes several fixed seats 808 and two rotating shafts 806. The fixed seats 808 are all fixedly mounted on the top of the support plate 2. The two rotating shafts 806 are rotatably connected to the fixed seats 808 respectively. Two clamping plates 807 are respectively fixedly sleeved on the two rotating shafts 806. The clamping mechanism 8 also includes two sliders 803, two racks 804, and two gears 805. The two gears 805 are respectively fixedly connected to the two rotating shafts 806. Both sliders 803 are threaded. The two racks 804 are fixedly connected to the two sliders 803 respectively and mesh with the two gears 805 respectively. When the two-way screw 802 rotates, it drives the two gears 805 to move relative to each other. The clamping mechanism 8 also includes a motor 801. The two-way screw 802 is rotatably connected to the bearing plate 2 and one end is fixedly connected to the output end of the motor 801. A fixed frame is fixedly installed at one end of the bearing plate 2 and the motor 801 is fixedly installed at one end of the fixed frame.

[0027] When the dust processing is completed and the sprayer 7 needs cleaning or maintenance, the operator starts the motor 801. The output end of the motor 801 drives the bidirectional lead screw 802 to rotate. When the bidirectional lead screw 802 rotates, it engages with the two sliders 803, causing the two sliders 803 to move towards each other. At this time, the two racks 804 move towards each other synchronously and mesh with the two gears 805, driving the two rotating shafts 806 to rotate in opposite directions. When the two rotating shafts 806 rotate, they drive the pressure plate 807 to rotate, so that the pressure plate 807 no longer presses against the mounting base 6. At this time, the mounting base 6 and the sprayer 7 can be disassembled vertically upward from the top of the support plate 2. The mounting base 6 and the sprayer 7 can be installed on the top of the support plate 2 by pressing. The positioning rod 202 can also perform preliminary positioning, reducing the difficulty of installation and disassembly, facilitating the overall maintenance of the sprayer 7, and making it highly applicable.

[0028] The working principle of this dust humidifier used in concrete mixing plants will be explained in detail below:

[0029] First, connect the water inlet of the sprayer 7 to the water supply equipment, and then connect the water supply equipment and the sprayer 7 to the control module. Then, remotely start the sprayer 7 and the water supply equipment through the control module. When pouring in the dust, the operator holds the handle 503 and pushes the sliding frame 501 and the baffle 502 horizontally through the handle 503. At this time, the sliding frame 501 slides on the outer wall of the two limit rods 402, and causes the compression spring 403 to deform until the baffle 502 no longer blocks the feeding trough 201. Then, the dust is poured into the humidifier body 1 through the feeding trough 201. Then, start the humidifier body 1 and the sprayer 7, and spray water while stirring the dust to perform humidification.

[0030] When the dust processing is completed and the sprayer 7 needs cleaning or maintenance, the operator starts the motor 801. The output end of the motor 801 drives the bidirectional lead screw 802 to rotate. When the bidirectional lead screw 802 rotates, it engages with the two sliders 803, causing the two sliders 803 to move towards each other. At this time, the two racks 804 move towards each other synchronously and mesh with the two gears 805, driving the two rotating shafts 806 to rotate in opposite directions. When the two rotating shafts 806 rotate, they drive the pressure plate 807 to rotate, so that the pressure plate 807 no longer presses against the mounting base 6. At this time, the mounting base 6 and the sprayer 7 can be disassembled vertically upward from the top of the support plate 2, which allows for more intuitive inspection and maintenance of the sprayer 7, reducing maintenance difficulty and improving maintenance efficiency.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
