technical field

The utility model relates to the field of mobile cleaning equipment, in particular to a cleaning vehicle.

Background technique

Existing mobile dedusting equipment often causes the filter equipment in the dedusting equipment to be clogged after being used for a period of time, and regular cleaning or replacement of the filter material is required to ensure long-term effective operation of the dedusting equipment. The cleaning vehicle in the mobile dust removal equipment will block the filter cartridge in the cleaning vehicle due to absorbing dust on the road surface after cleaning the road for a period of time, and the filter cartridge needs to be cleaned regularly, or even replaced. The existing cleaning vehicle adopts the principle of direct suction dust removal, and the dust removal device adopts a filter cartridge. As shown in Figure 1, the external structure of the filter cartridge 400 is a polygonal pleat structure 410, and the gas passes through the polygonal pleat structure 410 before filtering and enters the Inside the filter cartridge 400 (see the direction of the arrow for the gas flow direction), the gas is filtered through the polygonal pleat structure 410 to achieve dust removal. However, after long-term use, a large amount of dust often accumulates on the outside of the polygonal folded structure 410, which requires regular cleaning. The existing cleaning method adopts the method of regular back blowing, as shown in Figure 2, and additionally connected sequentially is often installed on the cleaning vehicle. Air valve 500, air tank 600 and air pump 700, the air outlet end of the air valve 500 is connected to the air outlet end of the filter cartridge 400, when cleaning is required, the air valve 500 is opened, and the high-pressure pulsed gas is charged as to the inside of the filter cartridge 400 to blow off the dust accumulated outside the polygonal pleated structure 410 . However, in actual use, there are many problems in the above-mentioned soot blowing method for the filter cartridge, for example, incomplete soot blowing, short service life of the filter cartridge, etc., which will be explained below.

Since the adjacent pleat vanes 411 in the outer polygonal pleat structure 410 of the filter cartridge 400 form an acute-angle structure 412 with a smaller angle, dust often accumulates at the acute-angle structure 412, and in the cleaning process, it is often inevitable to inhale water. Minute moisture will make the dust at the acute angle structure 412 fix on the polygonal pleated structure 410, and it will be difficult to blow it off with high-pressure pulse gas, resulting in long-term blockage, thereby reducing the filtration efficiency of the filter cartridge 400. On the one hand, the power of pumping is increased, on the other hand, the efficiency of dust removal is reduced. In addition, the arrangement of the filter cartridge 400 will also cause the failure of the soot blowing part. As shown in Figure 3 and Figure 4, the arrangement of the filter cartridge 400 in the sweeper can be arranged horizontally, as shown in Figure 3, or vertically. , as shown in Figure 4, when the filter cartridge 400 is arranged horizontally, the backflush pulse gas enters the inside of the filter cartridge 400 from one end of the filter cartridge 400 due to the longer length of the filter cartridge 400, away from the backflush pulse The gas power received by the filter cartridge 400 at the gas inlet end is weak, and the soot blowing efficiency is reduced; The dust is separated from the polygonal pleat structure 410 under the action of the pulse gas, but the dust located in the upper half of the filter cartridge 430 is separated from the polygonal pleat structure 410 under the action of the pulse gas, under the action of gravity, It is re-attached to the polygonal pleat structure 410, so that the soot blowing fails, and the filtration efficiency of the filter cartridge is generally reduced. In the long run, the ash accumulation effect attached to the filter cartridge 400 is improved, and finally it is difficult to separate from the filter cartridge, resulting in filter Cartridge 400 fails and needs to be replaced.

Moreover, when the cleaning vehicle is running on the road, it often inevitably passes through the water-logged road. At this time, the water on the ground will also contact the surface of the filter cartridge 400, and the filter cartridge 400 will be wetted, and the water will contact the surface of the filter cartridge 400. After the dust is mixed, the mesh of the filter cartridge 400 will be blocked, and it is difficult to remove it by using pulse gas, causing the filter cartridge to fail and be scrapped, resulting in high cost of use; in order to solve this problem, the gas sucked by the suction cup is used in the prior art The switching design, when entering the ground with water, the inhaled gas is directly discharged from the fan, and the gas inhaled from the dry ground is filtered through the filter cartridge. The switching is operated by human observation, which has high requirements for operators. When the operator does not switch on the wet ground, the filter cartridge 400 will be flooded and discarded. On the contrary, if it is switched on the dry ground by mistake, the air containing a large amount of dust sucked from the ground will be discharged to the surrounding environment under high pressure after passing through the fan. , causing dust.

In the utility model, a plurality of bag-type dust collectors 140 can be arranged in the box body 120. In order to ensure the uniformity of space utilization, a plurality of the bag-type dust collectors 140 can be evenly arranged side by side, as shown in Fig. 5 and Fig. As shown in 6, there are 8 bag-type dust collectors, four in a single row and two rows. Of course, 6 bag-type dust collectors can also be set according to the vehicle model, and three in a single row; each bag-type dust collector The dust removal air outlet 141 of 140 is provided with the air channel switching device 150, which is convenient for the individual control of each bag filter 140. In order to ensure that the blower fan 130 draws air smoothly, at least one of the multiple air channel switching devices 150 is in the position The first state is to ensure that at least one bag filter 140 is in the dust removal and filtering state, so that the unfiltered gas can enter the at least one bag filter 140 for filtering, and then enter the fan 130 .

The advantage of this is that while ensuring the working efficiency of the sweeper, soot blowing can also be taken into account, and no additional downtime is required for soot blowing, thereby ensuring that the sweeper can run for a long time. In the above description, the air inlet 131 of the fan can be connected to each airway switching device 150 by using separate pipes. In practice, the airway switching device 150 can also be connected to a common space, and then this space can be connected to the airway switching device 150. The fan air inlet 131 is connected. Of course, for each switching, an airway switching device corresponding to two bag filters can be used for each switching, and the operating cycle is set to four cycles. The number and cycle of switching the airway switching device each time can be set as required.

As shown in Figures 5 and 6, the bag filter 140 divides the upper part of the box body 120 to form a dust removal outlet bin 123, and the air outlet of the dust removal outlet bin 123 is connected to the fan inlet 131, When the air channel switching device 150 is in the first state, the dust removal air outlet 141 is connected with the fan air inlet 131 through the dust removal air outlet bin 123, thus ensuring that the air filtered by each bag filter 140 is Mix before entering the fan 130 to ensure stable air pressure.

As shown in FIG. 11 , the bag filter 140 in the present utility model includes a plurality of ribs 142 fixed to the box body 121 and arranged parallel to each other at intervals, and folded over the plurality of ribs 142 The filter bag 143 is located under the filter bag 143 and is covered by the filter bag 143. The first isolation net 144 connected to the ribs 142 is set on the plurality of ribs 142 and is located on the filter bag 143. Press down the second isolation net 145 of the filter bag 143; the first isolation net 144 is used to isolate the air intake surface of the adjacent filter bag 143, which ensures that when the soot blowing, the filter bag 143 expands, the adjacent The filter bag 143 of the filter bag 143 will not fit, thereby making the soot blowing ineffective; and the second isolation net 145 is set on the air outlet surface of the filter bag 143, which can ensure that when the bag filter 140 is in normal filtering process, the fan The draft at 130 will not suck the adjacent filter bags 143 together, thereby reducing the filtration efficiency.

In order to further prevent the adjacent filter bags 143 of the bag filter 140 from sucking together, an isolation structure can be provided at the bent part, specifically, the part of the filter bag 143 between adjacent ribs 142 forms a bent part 1431 , the second isolation net 145 extends from the position of the rib 142 to the bottom of the bent portion 1431 , ensuring that the bent portion 1431 of the filter bag 143 will not be sucked together.

The filter bag 143 in each bag filter 140 in the utility model is an integral needle-punched felt cloth, with both ends fixed, and the middle part is bent and placed on each rib; specifically, as shown in Figure 11, the bag Type dust collector 140 also includes a sealing briquetting block 146, the airway switching device 150 seals and fixes the edge of the filter bag 143 and the box body 121 through the sealing briquetting block 146, and the sealing briquetting block 146 seals the filter bag The edge of 143 is pressed on the fixed plate 147 fixedly connected with the box body 121; the above-mentioned sealing pressing block 146 can be a sealing rubber block, which is pressed on the sealing pressing block 146 by the gravity of the airway switching device 150, so that all The sealing of the sealing pressing block 146 to the edge of the filter bag 143, specifically, acts on the sealing pressing block 146 through the fixing plate 154 of the switching device.

As shown in Figure 12 and Figure 5, the bag filter 140 is arranged on the upper part of the box body 120 in the utility model, and the lower part is set as the ash storage box 124, and the remaining dust after being filtered by the bag filter 140 falls In the ash storage box 124, the lower part of the box body (that is, the ash storage box 124) is provided with an air inlet 1241 connected to the suction cup 160, which can be connected by flexible pipes and/or rigid pipes. A water filter 170 is provided at the position of the air inlet 1241, and the water filter 170 is used to block the gas coming in from the air inlet 1241 (the gas sucked up from the ground by the suction cup 160). The stagnant water is also pumped into the box body. If the stagnant water is not blocked at this time, the stagnant water will be sprayed with higher energy and flow rate as in the casing 120, so that the relatively stable environment in the ash storage box 124 becomes If the dust in the ash storage box 124 is raised again, the working pressure of the bag filter 140 is increased; in addition, the suction cup 160 also removes larger garbage on the road surface, such as garbage bags, Leaves, etc., are sucked into the casing, and the larger garbage entering can be blocked by the water filter, reducing the speed when entering the casing 120, so that the environment in the casing 120 is stable, and it is beneficial to filter dust ; In practice, the water filter is a chain suspended side by side (the ring structure is successively looped to form a chain structure), and the gas can flow out from the gap in the chain, which also reduces the gas flow rate and stabilizes the air pressure inside the box; while the accumulated water , Larger garbage will be shot on the chain, decelerated and landed at the bottom of the box.

Rubber plates 180 are arranged on both sides of the water filter 170 inside the box, and the plastic plates 180 are used to disturb the airflow, so that the airflow (the black arrow in the figure) needs to pass over the rubber plates 180 to enter the box. Filtration can also play a role in intercepting water mist at the same time. The flexible plate is suitable for absorbing the energy of the injected gas. The material of the rubber plate 180 can be rubber, flexible plastic, etc.

In order to isolate larger garbage from being sucked into the bag filter, causing the bag filter to fail, (for example, when the plastic bag is sucked, it will be attached to the filter bag 143, causing a large area of failure), as shown in the figure As shown in 5, a primary filter 190 is arranged inside the box on the dust removal air inlet of the bag filter 140, and a monolithic primary filter 190 is set at the lower part of the bag filter 140 to isolate the lower part as the above-mentioned Ash storage box 124 of. In practice, the primary filter 190 may adopt a partition 192 with evenly distributed meshes 191; the primary filter 190 may be a multi-layer partition, and the meshes 191 in the partitions of adjacent layers are staggered from each other.

When working, the suction cup 160 enters the sundries, garbage, and accumulated water on the ground into the box body 120 through the pipeline and the air inlet 1241, and the mixture contacts the water filter 170 to decelerate, so that larger garbage falls, After the accumulated water falls, the gas passes through the rubber plate 180 and the water filter 170 and then enters the bag filter 140 for dust removal, and the filtered gas enters the blower fan 130 and is discharged into the atmosphere; when a certain bag filter When the filter 140 needs soot blowing, the high-pressure air from the air outlet of the fan 130 is introduced into the air outlet of the bag filter 140, and the filter bag 143 in the bag filter 140 is blown back. Make it expand, so that the dust on the filter bag 143 falls, soot blowing treatment is realized; when there are multiple bag type dust collectors 140, the soot blowing time of each bag type dust collector 140 is set at intervals to ensure continuous and stable cleaning efficiency .

Through the above technical means, the utility model ensures the effectiveness of soot blowing and the continuous operation of the sweeper. At the same time, the filter bag 143 in the sweeper has a good waterproof effect and is not afraid of being wetted by water, so that the sweeper can clean the dust in the accumulation area. The road running on water expands the application scenarios.
