Description

Technical Field

[0001] This utility model relates to the field of dust suppression spray technology, specifically to a dust suppression vehicle anti-clogging spray device. Background Technology

[0002] To reduce dust generated during construction, dust suppression vehicles are commonly used to spray water mist at construction sites, filling the air with water vapor. The atomized water vapor condenses with dust particles in the air, causing them to fall quickly to the ground, effectively preventing large amounts of dust from spreading in the air. This paper provides an anti-clogging spray device for dust suppression vehicles. A search revealed Chinese patent application number "CN202320955459.1," which discloses an anti-clogging spray device for dust suppression vehicles, comprising: a vehicle body and a spray cylinder. A base is provided on the upper surface of the rear of the vehicle body, and a servo motor is installed inside the base. A support shaft is provided on the upper surface of the base, and a movable plate is provided at the upper end of the support shaft. Support plates are symmetrically welded to the upper surface of the movable plate. A spray cylinder is mounted between the support plates via a rotating shaft. A spray pump and a fan are installed inside one end of the spray cylinder. A water-blocking ring is provided on the inner wall of the other end of the spray cylinder, and a filter screen is provided at the air inlet of the spray cylinder.

[0003] However, existing technologies have the following problems: Existing technology only uses a water-blocking ring to prevent water droplets on the inner wall of the spray nozzle from sliding down to the filter screen at the bottom of the nozzle, thus avoiding the dust on the filter screen from getting wet and condensing into clumps and causing blockages. However, in actual use, water mist will still condense on the water-blocking ring, forming water droplets that will continue to wet the dust on the filter screen, resulting in poor practicality.

[0004] Therefore, this invention aims to provide a dust suppression vehicle anti-clogging spray device that, during use, increases the airflow velocity when air is delivered from the air supply component to the spray nozzle, thereby accelerating the rapid ejection of water mist from the nozzle and reducing the time the water mist remains inside. This prevents a large amount of water mist from accumulating inside the nozzle and condensing into numerous water droplets. Simultaneously, the multiple flow-enhancing and water-blocking covers effectively prevent water droplets from flowing towards the filter screen, thus avoiding wetting the dust on the filter screen. This improves the practicality and reliability of the device. Utility Model Content

[0005] To address the aforementioned technical problems, the purpose of this utility model is to overcome the shortcomings of existing technologies that rely solely on water-blocking rings to prevent water droplets from sliding down the inner wall of the spray nozzle onto the filter screen at the bottom of the nozzle, thus avoiding dust condensation and blockage on the filter screen. In practice, however, water mist still condenses on the water-blocking rings, forming droplets that continue to wet the dust on the filter screen, resulting in poor practicality. This invention provides a dust suppression vehicle anti-clogging spray device that uses multiple flow-enhancing and water-blocking covers to increase the airflow velocity from the air supply component to the spray nozzle, accelerating the rapid ejection of water mist from the nozzle and reducing the time water mist remains inside. This prevents a large amount of water mist from accumulating and condensing into droplets. Simultaneously, the multiple flow-enhancing and water-blocking covers provide multiple layers of protection against water droplets flowing towards the filter screen and wetting the dust, thus improving practicality and reliability.

[0006] To achieve the above objectives, this utility model provides a dust suppression vehicle anti-clogging spray device, the spray device comprising: a spray cylinder, an atomizing nozzle assembled in the spray cylinder, and an air supply assembly; The air supply assembly includes: an air supply housing, a fan, and a flow-boosting and water-blocking cover; wherein... An air supply housing is detachably fixed to the air supply end of the spray cylinder. A filter screen is detachably mounted on the port of the air supply housing away from the spray cylinder. A fan is coaxially arranged inside the air supply housing. Multiple flow-enhancing and water-blocking covers with gradually decreasing diameters at their outlets are detachably fixed inside the air supply housing between the fan and the filter screen and at equal intervals, in the direction from the filter screen to the atomizing nozzle.

[0007] Preferably, each of the flow-boosting and water-blocking covers is detachably fitted with a water-absorbing sleeve made of highly absorbent material.

[0008] Preferably, the absorbent sleeve can be a sponge sleeve or an absorbent sleeve made of polyacrylamide or polyacrylic acid.

[0009] Preferably, each of the flow-boosting and water-blocking covers is detachably fitted with the water-absorbing sleeve via multiple fixing clips; wherein, Each of the fixing clips is a ring structure, and each of the fixing clips has an opening. The surface of each flow-increasing and water-blocking cover is equally spaced and partially recessed to form multiple fixing slots that correspond to and cooperate with the fixing clips. The water-absorbing sleeve fitted on the flow-increasing and water-blocking cover is respectively secured to the corresponding fixing slot by the multiple fixing clips.

[0010] Preferably, the end portion of the air supply housing extends outward to form a fixing part, and the surface of the fixing part is uniformly provided with external threads, and the inner wall of the end of the spray cylinder is uniformly provided with internal threads that cooperate with the external threads. The spray cylinder and the air supply housing are threaded together by the cooperation of the internal and external threads.

[0011] Preferably, the filter screen is threadedly connected to the air supply housing, and each of the flow-boosting and water-blocking covers is threadedly connected to the inner wall of the air supply housing.

[0012] According to the above technical solution, the beneficial effects of the dust suppression vehicle anti-clogging spray device provided by this utility model in use are as follows: (1) When in use, the fan is started to draw the outside air into the air supply housing after it is filtered through the filter screen. The air drawn into the air supply housing passes through multiple flow-increasing and water-blocking covers in sequence and enters the spray cylinder. The water mist sprayed by the spray pump in the spray cylinder is quickly pushed out from the air outlet of the spray cylinder. Since the flow-increasing and water-blocking covers with gradually decreasing outlet diameters are coaxially fixed in sequence in the air supply housing, on the one hand, after being drawn into the air supply housing by the air supply component, the wind speed increases when it flows into the spray cylinder through the flow-increasing and water-blocking cover with the smallest outlet diameter. This can quickly push out the water mist in the spray cylinder, reduce the time that the atomized water mist stays in the spray cylinder, and thus prevent a large amount of water mist from contacting the inner wall of the spray cylinder and forming water droplets, thereby reducing the amount of water droplets formed on the inner wall of the spray cylinder. On the other hand, the multiple flow-increasing and water-blocking covers can repeatedly block the water droplets formed on the inner wall of the spray cylinder from flowing into the air supply component and wetting the dust on the filter screen, which improves its practicality and reliability. The effect is significantly better than the existing technology.

[0013] (2) In contrast to the prior art which assembles the fan between the water baffle ring and the spray pump, this application sets multiple flow-increasing and water-blocking covers between the spray pump and the fan. The multiple flow-increasing and water-blocking covers can protect the fan, reduce the contact between the water mist in the spray tube and the fan, thereby waterproofing the fan motor and extending the service life of the fan.

[0014] In summary, this utility model increases the airflow velocity when air is delivered from the air supply component to the spray nozzle by using multiple flow-enhancing and water-blocking covers. This accelerates the rapid ejection of water mist from the spray nozzle, reducing the time the water mist remains inside the nozzle and preventing a large amount of water mist from accumulating and condensing into water droplets. At the same time, the multiple flow-enhancing and water-blocking covers can effectively prevent water droplets from flowing to the filter screen and causing dust to accumulate on the filter screen, thus improving its practicality and reliability.

[0015] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0018] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0019] like Figure 1-4 As shown, the present invention provides a dust suppression vehicle anti-clogging spray device, the spray device comprising: a spray cylinder 1, an atomizing nozzle 2 assembled in the spray cylinder 1, and an air supply assembly; The air supply assembly includes: an air supply housing 3, a fan 4, and a flow-boosting and water-blocking cover 5; wherein... An air supply housing 3 is detachably fixed to the air supply end of the spray cylinder 1. A filter screen 7 is detachably mounted on the port of the air supply housing 3 away from the spray cylinder 1. A fan 4 is coaxially arranged inside the air supply housing 3. A plurality of flow-enhancing and water-blocking covers 5 are detachably fixed and coaxially spaced inside the air supply housing 3 between the fan 4 and the filter screen 7, with the diameter of the air outlet gradually decreasing from the filter screen 7 to the atomizing nozzle 2.

[0020] In the above scheme, the fan 4 includes a turbine fan and a motor for driving the turbine fan. The motor starts the impeller to rotate, generating centrifugal force, which converts kinetic energy into pressure energy through the vortex casing, achieving continuous exhaust. This fan is characterized by its small size and large air volume. The surface of the motor of the fan 4 is coated with a waterproof and corrosion-resistant coating to provide waterproofing and corrosion protection.

[0021] In use, by starting the fan 4, the outside air is filtered through the filter screen 7 and then drawn into the air supply housing 3. The air drawn into the air supply housing passes through multiple flow-enhancing and water-blocking covers 5 in sequence before entering the spray cylinder 1. The water mist sprayed by the spray pump 2 in the spray cylinder 1 is then quickly pushed out of the air outlet of the spray cylinder 1. Because the air supply housing 1 is coaxially fixed with flow-enhancing and water-blocking covers 5 of gradually decreasing outlet diameter in sequence, on the one hand, after being drawn into the air supply housing by the air supply component, the flow-enhancing and water-blocking covers with the smallest outlet diameter are drawn out by the flow-enhancing covers 5 of gradually decreasing outlet diameter. When the water-blocking cover 5 flows into the spray cylinder 1, the wind speed increases, which can quickly push the water mist out of the spray cylinder 1 and reduce the time that the atomized water mist stays in the spray cylinder 1. This can prevent a large amount of water mist from contacting the inner wall of the spray cylinder 1 and forming water droplets, thus reducing the amount of water droplets formed on the inner wall of the spray cylinder 1. On the other hand, the multiple flow-enhancing water-blocking covers 5 can repeatedly block the water droplets formed on the inner wall of the spray cylinder 1 from flowing into the air supply component and wetting the dust on the filter screen 7, which improves its practicality and reliability and is significantly better than the existing technology.

[0022] In addition, compared with the prior art which assembles the fan 4 between the water baffle ring and the spray pump, this application sets multiple flow-increasing and water-blocking covers 5 between the spray pump 2 and the fan 4. The multiple flow-increasing and water-blocking covers 5 can protect the fan 4, reduce the contact between the water mist in the spray cylinder 1 and the fan 4, thereby waterproofing the motor of the fan 4 and extending the service life of the fan 4.

[0023] In summary, this utility model increases the airflow velocity when air is delivered from the air supply component to the spray cylinder 1 by using multiple flow-enhancing and water-blocking covers 5. This accelerates the rapid ejection of water mist from the spray cylinder 1, reducing the time the water mist remains inside the spray cylinder 1. This prevents a large amount of water mist from accumulating inside the spray cylinder 1 and condensing into a large number of water droplets. At the same time, the multiple flow-enhancing and water-blocking covers 5 can effectively block water droplets from flowing to the filter screen 7, thus preventing dust accumulation on the filter screen and improving its practicality and reliability.

[0024] It should be noted that this utility model only improves the spray cylinder 1 and the air supply device of the anti-clogging spray device for dust suppression vehicles disclosed in patent application number "CN202320955459.1" cited in the background art; other structural features remain unchanged. Figure 1As shown, the dust suppression vehicle anti-clogging spray device of this application further includes: a base mounted on the dust suppression vehicle, a servo motor, a support shaft, and a movable plate disposed inside the base; wherein, a support shaft is provided on the upper surface of the base, a movable plate is provided at the upper end of the support shaft, support plates are symmetrically welded on the upper surface of the movable plate, and a spray cylinder 1 is installed between the support plates via a rotating shaft, a pitch adjustment device is provided on the upper surface of the movable plate, the upper end of the pitch adjustment device is movably connected to the outer wall of the spray cylinder 1, and the lower end of the pitch adjustment device is rotatably installed on the upper surface of the movable plate, and the pitch adjustment device is composed of a telescopic rod and a hydraulic pump. The pitch adjustment device composed of the telescopic rod and the hydraulic pump allows people to flexibly control the pitch angle of the spray cylinder. When the telescopic rod on the pitch adjustment device returns to its original position, it can pull one end of the spray cylinder 1, causing the other end of the spray cylinder 1 to tilt upwards, making it easy for people to tilt the spray nozzle of the spray cylinder 1 upwards, avoiding the spray nozzle of the spray cylinder 1 pointing towards pedestrians or vehicles, without the need for people to manually adjust the pitch angle of the spray cylinder 1.

[0025] Atomizing nozzles are fixedly installed at the water outlet of atomizing pump 2. One end of the spray pump 2 is connected to a connecting pipe, and the other end of the connecting pipe is connected to a water tank mounted on the dust suppression vehicle. The spray pump continuously pumps water through the connecting pipe, allowing the atomizing nozzles to continuously spray water mist.

[0026] In a preferred embodiment of this utility model, each of the flow-boosting and water-blocking covers 5 is detachably fitted with a water-absorbing sleeve 6 made of highly absorbent material.

[0027] In the above scheme, during use, when water droplets formed on the inner wall of the spray cylinder 1 slide towards the blower assembly, multiple flow-increasing and water-blocking covers 5 block the water droplets and absorb and store the blocked water droplets inside the water-absorbing sleeve 6. This effectively prevents the water on the inner wall of the spray cylinder 1 from flowing onto the filter screen 7, causing the dust on its surface to wet and clump together, thus clogging the mesh.

[0028] In a preferred embodiment of this utility model, the absorbent sleeve 6 can be a sponge sleeve or an absorbent sleeve made of polyacrylamide or polyacrylic acid.

[0029] In the above solutions, sponges and polyacrylamide or polyacrylic acid materials exhibit excellent water absorption, capable of absorbing large amounts of water. They possess superior water absorption and retention properties. The sponge absorbent sleeves, in particular, are elastic and reusable.

[0030] In a preferred embodiment of this utility model, each of the flow-increasing and water-blocking covers 5 is detachably fitted with the water-absorbing sleeve 6 via multiple fixing clips 8; wherein, Each of the fixing clips 8 is a ring structure, and each of the fixing clips 8 has an opening. On the surface of each of the flow-increasing and water-blocking covers 5, there are multiple fixing slots 9 that are equally spaced and partially recessed inward, which correspond to and cooperate with the fixing clips 8. The water-absorbing sleeve 6, which is fitted on the flow-increasing and water-blocking cover 5, is respectively secured to the corresponding fixing slots 9 by the multiple fixing clips 8.

[0031] In the above solution, when in use, the water-absorbing sleeve 6 is put on the flow-increasing and water-blocking cover 5, and the multiple fixing clips 8 are opened and locked into the corresponding multiple fixing slots 9 in sequence, thereby fixing the water-absorbing sleeve 6 on the flow-increasing and water-blocking cover 5. Disassembly is simple, thus facilitating the replacement of the water-absorbing sleeve.

[0032] In a preferred embodiment of this utility model, the end portion of the air supply housing 3 extends outward to form a fixing part, and the surface of the fixing part is uniformly provided with external threads, and the inner wall of the end of the spray cylinder 1 is uniformly provided with internal threads that cooperate with the external threads. The spray cylinder 1 and the air supply housing 3 are threaded together by the cooperation of the internal and external threads.

[0033] In the above solution, the threaded connection method makes disassembly simple and facilitates the quick removal of the air supply component for replacement and maintenance of the flow-enhancing water-blocking cover 5.

[0034] In a preferred embodiment of this utility model, the filter screen 7 is threadedly connected to the air supply housing 3, and each of the flow-boosting and water-blocking covers 5 is threadedly connected to the inner wall of the air supply housing 3.

[0035] The above scheme facilitates the replacement and maintenance of the flow-increasing water-blocking cover 5 and the filter screen 7.

[0036] In summary, the dust suppression vehicle anti-clogging spray device provided by this utility model overcomes the problem that the existing technology only uses a water-blocking ring to prevent water droplets on the inner wall of the spray cylinder from sliding down to the filter screen at the bottom of the cylinder to avoid the dust on the filter screen from getting wet and condensing into clogging. However, in actual use, water mist will still condense on the water-blocking ring to form water droplets, which will continue to wet the dust on the filter screen, resulting in poor practicality.

[0037] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0039] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
