Description

Technical Field

[0001] The invention belongs to the field of dust collection vehicles, and in particular relates to a double-pulse back-blowing dust cleaning device. Background Art

[0002] Compared with traditional wet sweepers, vacuum cleaners have many advantages: the operation is completed entirely with airflow, combining blowing and suction, and no secondary dust. No brushes or water are needed, saving energy, and dry suction. Once the car passes, the ground is clean. The cleaning effect is good, from dust of tens of microns to general pebbles, leaves and other debris can be effectively removed, with a cleaning efficiency of more than 98%, which can be said to be "sweeping ten times is not as good as sucking once."

[0003] All vacuum trucks use airflow to complete their operations, using the movement of airflow to collect and store dust and garbage, direct suction with negative pressure, and the principles of aerodynamics.

[0004] The cloth bag is the most important component in the vacuum truck. If too much dust accumulates on the cloth bag, it will clog the cloth bag and fail to achieve a good vacuuming effect. Therefore, the cloth bag needs to be dusted regularly, while conventional dust removal methods such as patting and back-blowing have poor dust removal effects and are difficult to clean in time.

DETAILED DESCRIPTION

[0027] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.

[0028] like Figure 1-6 As shown, the present invention provides a double-pulse back-blowing cleaning device, comprising a vehicle body 1 and a box body 3, a dust pan 2 is arranged at the bottom of the vehicle body 1, a cloth bag 9 is arranged in the box body 3, the cloth bag 9 is connected to the induced draft fan 22, the dust pan 2 is connected to the box body 3 through a dust suction pipe, a plurality of dust suction components 4 are arranged in the box body 3, the dust suction components 4 include an air duct 8, and a plurality of cloth bags 9 are connected to the bottom of the air duct 8; a connecting cylinder 7 is connected to the end of the air duct 8, and a back-blowing cylinder 5 and a negative pressure cylinder 6 are respectively connected to the upper and lower parts of the connecting cylinder 7; a control valve which can control the back-blowing cylinder 5 and the negative pressure cylinder 6 to be alternately connected to the connecting cylinder 7 is arranged in the connecting cylinder 7; the back-blowing cylinder 5 is connected to a pulse wind generator 10, and the negative pressure cylinder 6 is connected to the induced draft fan 22.

[0029] The device is provided with multiple groups of dust collection components 4, and the control valve of one group is controlled to work in sequence, so that the dust collection components 4 in the dust collection state can be changed to the dust cleaning state, so that the dust can be cleaned in time during operation without reducing the dust collection effect.

[0030] The device can increase the dust collection area by arranging multiple groups of cloth bags 9 in each group of dust collection components 4. The increased number of cloth bags 9 can reduce the probability of cloth bag clogging and improve work efficiency.

[0031] The device is connected to the back-blowing air cylinder 5 by a pulse wind generator 10, so that during dust cleaning, the dust adsorbed on the periphery of the bag 9 can be shaken off by the pulse wind, thereby improving the dust cleaning effect.

[0032] The device sets a control valve in the dust collection assembly 4 so that the dust cleaning process will not be disturbed by negative pressure, that is, the energy of the pulse generator 10 will not be partially offset by the induced draft fan, thereby saving resources and improving the dust cleaning efficiency and effect.

[0033] like Figure 3 As shown, there are eight groups of dust collecting components 4, which are evenly distributed in the box body 3. The more groups of dust collecting components 4 there are, the smaller the impact on the dust collecting effect during dust collection. During dust collection, the control valve of one group of dust collecting components 4 is controlled to work in sequence, so that each group of dust collecting components 4 can be cleaned in sequence, so that the device can remove dust in time during work, reduce the probability of bag clogging, and increase the service life of the bag.

[0034] like Figure 4 As shown, the control valve includes a cylinder 11 fixedly connected to the top of the back-blowing cylinder 5, a control rod 12 is arranged inside the cylinder 11, a valve plate 13 is fixedly connected to the bottom of the control rod 12, and a rubber pad is arranged on the bottom end surface of the valve plate 13; through holes are opened at the upper and lower parts of the connecting cylinder 7, and the valve plate 13 is located inside the connecting cylinder 7.

[0035] The working principle of the control valve is: by controlling the cylinder 11 to work, the control rod 12 is moved downward, so that the connecting cylinder 7 and the negative pressure cylinder 6 are disconnected, the connecting cylinder 7 and the back-blowing air cylinder 5 are connected, and the pulse wind generator 10 works, so that the dust on the outside of the bag 9 is shaken off by the pulse wind.

[0036] After the dust cleaning operation continues for 5 seconds, the air cylinder 11 is controlled to work and the control rod 12 is moved upward, so that the connecting tube 7 and the negative pressure tube 6 are connected, and the connecting tube 7 and the back-blowing air tube 5 are disconnected, and the induced draft fan 22 is controlled to work, so that the dust collection operation can continue.

[0037] After a one-minute interval from the cleaning operation of the previous dust collecting component 4, the next dust collecting component 4 starts the cleaning operation, and the cycle is repeated. The dust collecting operation will not be disturbed during the cleaning process.

[0038] like Figure 4 As shown, the bags 9 in each group of the dust collection components 4 are evenly fixed at the bottom of the air duct 8.

[0039] The greater the number of cloth bags 9 is, the less likely the cloth bags 9 are to be clogged, and the better the dust collection effect is.

[0040] like Figure 5 As shown, the pulse wind generator 10 includes a straight valve 14 connected to the back-blowing cylinder 5, the end of the straight valve 14 is connected to an air bag 16, and the end of the air bag 16 is connected to a blower 17. Figure 6As shown, the straight valve 14 includes a valve body, a rotating plate 19 is rotatably connected in the valve body, a rotating shaft 18 is fixedly connected to the rotating plate 19, and a motor 15 is coaxially fixedly connected to the rotating shaft 18; the rotating shaft 18 is rotatably connected to the valve body. The material of the airbag 16 is rubber. The material of the airbag 16 allows it to store more gas, and after being connected to the back-blowing cylinder 5, it can blow out faster and more pulse wind.

[0041] The motor 15 drives the shaft 18 to rotate, thereby realizing the circumferential rotation of the rotating plate 19 in the straight valve 14, so that the connection between the air bag 16 and the back-blowing air cylinder 5 can be intermittently controlled, thereby generating pulse wind, which is beneficial to the dust cleaning operation.

[0042] like Figure 2-3 As shown, the blower 17 in each group of the dust collection components 4 is connected to an air inlet pipe 20, and the end of the air inlet pipe 20 passes through the box body 3 and is fixedly connected to the box body 3; the induced draft fan 22 in each group of the dust collection components 4 is connected to an air outlet pipe 21, and the end of the air outlet pipe 21 passes through the box body 3 and is fixedly connected to the box body 3.

[0043] The air inlet pipe 20 is used to supply external gas to the blower 17 , and the air outlet pipe 21 is used to discharge the gas exhausted by the induced draft fan 22 out of the box body 3 .

[0044] When the device is in use, the default positions of the control rod 12 and valve plate 13 of each control valve group are located on the upper side of the connecting tube 7, and the induced draft fan 22 in each dust collection component 4 is working to generate negative pressure, so that the device can suck dust and garbage from the outside into the box body 3, and the dust will be partially attached to the outer periphery of the bag 9, and the garbage will fall to the bottom of the box body 3. Every one minute, the control valve of a group of dust collection components 4 is controlled to work in turn, so that the control rod 12 moves down with the valve plate 13, and the pulse wind generator 10 works for 5 seconds, so that each group of dust collection components 4 can be cleaned in turn, and it will not have a great impact on dust collection, and it can also clean dust in time to increase the service life of the bag.

[0045] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0046] Although the terms such as vehicle body 1, dust collecting disc 2, box body 3, dust collecting assembly 4, back blowing cylinder 5, negative pressure cylinder 6, connecting cylinder 7, air duct 8, cloth bag 9, pulse wind generator 10, cylinder 11, control rod 12, valve plate 13, straight valve 14, motor 15, air bag 16, blower 17, rotating shaft 18, rotor 19, air inlet pipe 20, air outlet pipe 21, induced draft fan 22 are used more frequently in this article, the possibility of using other terms is not excluded.
