[0045] See also Figures 1 to 5 The present embodiment provides a cargo box residual material collection device, including an outer shell, a suction mechanism 2, a filtering mechanism 3 and a dust removal mechanism 4, the outer shell includes a box body 1, the box body 1 is provided with a storage bin 11 and a filtering bin 12 which are interconnected, the storage bin 11 is provided with a suction port 111, the filtering bin 12 is provided with an air outlet 125, the suction mechanism 2 is provided on the box body 1, located outside the filtering bin 12, and connected to the air outlet 125, the filtering mechanism 3 is provided in the filtering bin 12, and is used to filter dust particles entering the air outlet 125, and the dust removal mechanism 4 is provided on the box body 1, and is used to remove dust particles attached to the filtering mechanism 3.

[0046] The interior of the box 1 is divided into two interconnected areas, namely, a storage bin 11 and a filter bin 12. The storage bin 11 is used to collect materials, and a suction port 111 is provided on the side wall of the storage bin 11 so as to suck in the residual material and dust mixture from the outside through the suction mechanism 2. The filter bin 12 is adjacent to the storage bin 11, and a passage is connected between the two to ensure smooth airflow. The filter bin 12 is provided with an air outlet 125 so as to indirectly connect the suction mechanism 2 with the storage bin 11.

[0047] The suction mechanism 2 is mounted on the housing 1 of the outer shell, located outside the filter bin 12, and connected to the air outlet 125 of the filter bin 12 through a pipeline. The suction mechanism 2 is usually driven electrically or pneumatically, and can generate sufficient negative pressure to suck the residual material and dust mixture in the storage bin 11 through the suction port 111, and filter it through the filter mechanism 3 in the filter bin 12.

[0048] The dust removal mechanism 4 is provided on the housing and can be located inside or outside the filter chamber 12, and is used to remove dust particles attached to the filter mechanism 3. The dust removal mechanism 4 can be provided in a variety of ways, such as vibration dust removal, back-blowing dust removal, pulse dust removal, etc. In actual operation, when the dust on the filter mechanism 3 accumulates to a certain extent, the dust removal mechanism 4 will start to remove the dust from the filter mechanism 3 by vibration, back-blowing or pulse, so as to restore the filtering efficiency of the filter mechanism 3, which is beneficial to the subsequent suction operation.

[0049] When it is necessary to collect the residual material, the suction mechanism 2 is started to generate negative pressure, and the residual material and dust mixture in the storage bin 11 is sucked in through the suction port 111. The mixture first enters the storage bin 11, and then enters the filter bin 12. After being filtered by the filter mechanism 3, the dust particles are intercepted on the filter mechanism 3, and the clean air is discharged through the air outlet 125, solving the problem of gas pollution discharged into the air. With the continuous use of the filter mechanism 3, the dust accumulation on it will gradually increase, resulting in a decrease in the filtering efficiency. At this time, the dust removal mechanism 4 is started to remove the dust from the filter mechanism 3 and restore its filtering efficiency.

[0050] See also Figure 1In this embodiment, the dust removal mechanism 4 includes an air bag 41, and the air bag 41 is provided with an extended air blowing pipe 411, and the air blowing pipe 411 is located in the filter bin 12 and above the filter mechanism 3. The air blowing port 412 of the air blowing pipe 411 faces the inner side (i.e., the upper side) of the filter mechanism 3, and the inner side of the filter mechanism 3 faces the air outlet 125. The air bag 41 can be arranged in the filter bin 12 and above the filter mechanism 3. A support plate for supporting the air bag 41 and the air blowing pipe 411 can be provided on the upper part of the filter bin 12. A certain amount of compressed air or other clean gas is stored inside the air bag 41. The air blowing pipe 411 extending from the air bag 41 passes through the outer wall of the box body 1 and extends into the filter bin 12. The inner side of the filter mechanism 3 faces the air outlet 125, and the air outlet faces the inner side of the filter mechanism 3. This design ensures that the clean gas blown out from the air blowing pipe 411 can directly impact the dust particles, thereby effectively blowing the dust particles to the outside, reducing the contamination of the air blowing port 412, and on the other hand, it is also beneficial to the subsequent suction operation. The dust removal mechanism 4 adopts the design of the air bag 41 and the air blowing pipe 411, which has a simple structure and is easy to maintain, reducing the maintenance cost and difficulty.

[0051] See also Figure 1 , Figure 3 and Figure 5 In this embodiment, the dust removal mechanism 4 also includes a solenoid valve 42, which is connected to the air bag 41. The solenoid valve 42 releases the high-pressure air stored in the air bag 41 into the air blowing pipe 411 to impact the inner side of the filter cartridge 32 in the reverse direction, blowing away the dust adhering to the outer side of the filter cartridge 32, and under the impact of the high-pressure airflow, the filter cartridge 32 is also vibrated to remove dust.

[0052] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, the filtering mechanism 3 includes a mounting frame 31 and a filter cartridge 32, and the filtering bin 12 includes an upper clean chamber 121 and a lower ash chamber 122. A mounting frame 31 is provided at the boundary between the upper clean chamber 121 and the lower ash chamber 122. The upper clean chamber 121 is provided with an air outlet 125 and is connected to the dust removal mechanism 4 (air bag 41, air blowing pipe 411). The lower ash chamber 122 is connected to the storage bin 11. The mounting frame 31 is provided with a hole for accommodating the filter cartridge 32. The filter cartridge 32 is arranged on the mounting frame 31 and extends downward through the hole. An air outlet 412 is provided above the filter cartridge 32.

[0053] The mounting frame 31 usually has a solid structure and appropriate size to ensure that the filter cartridge 32 can be stably mounted thereon. The mounting frame 31 can be detachably mounted in the filter bin 12 by bolts and buckles, which is convenient for disassembly and maintenance. The mounting frame 31 and the filter cartridge 32 separate the filter bin 12 into an upper clean chamber 121 and a lower ash chamber 122. The upper clean chamber 121 is located above the lower ash chamber 122. The lower ash chamber 122 is an ash chamber with dust, and the upper clean chamber 121 is a clean chamber after filtration. Dust particles will be intercepted by the filter cartridge 32, and the lower ash chamber 122 collects dust particles falling from the filter cartridge 32. Clean air enters the upper clean chamber 121 through the filter cartridge 32 and is discharged from the air outlet 125. Among them, the upper side of the filter cartridge 32 is the inner side of the filter mechanism 3 mentioned above, and the air blowing pipe 411 is above the filter cartridge 32, and its air blowing port 412 faces downward to the upper side of the filter cartridge 32.

[0054] See also Figure 1 , Figure 2 and Figure 3 In this embodiment, there are multiple filter cartridges 32, which are arranged in rows and columns, one filter cartridge 32 corresponds to one hole, and each filter cartridge 32 is supported on the mounting frame 31 through an independent hole. There are multiple air blowing pipes 411, one air blowing pipe 411 is provided above a row of filter cartridges 32, one air blowing pipe 411 has multiple air blowing ports 412, and in a row of filter cartridges 32, one air blowing port 412 is provided above each filter cartridge 32.

[0055] Figure 3 As shown, 20 filter cartridges 32 are arranged in 5 rows and 4 columns on the mounting frame 31, and 5 air blowing pipes 411 are correspondingly arranged above the 5 rows of filter cartridges 32, each air blowing pipe 411 has 4 air blowing ports 412, and one solenoid valve 42 controls the air blowing of one air blowing pipe 411, and 4 filter cartridges 32 can be back-blown at the same time to ensure that each filter cartridge 32 can be evenly purged. Multiple air blowing pipes 411 and air blowing ports 412 work simultaneously, which can remove dust particles on the filter cartridge 32 more quickly, thereby improving the dust removal effect.

[0056] See also Figure 3 In this embodiment, the housing further comprises a rear cover door 6, and the rear part of the housing 1 is provided with the rear cover door 6, which is used to open or close the filter chamber 12. The rear cover door 6 is hingedly mounted at the rear part of the housing 1, and has a handle 61, which can be opened and closed manually. When the rear cover door 6 is opened, the filter chamber 12 is inside, and the function is to disassemble and maintain the high-precision filter mechanism 3. When the filter cartridge 32 is seriously clogged, the rear cover door 6 can be opened to manually clean the filter cartridge 32.

[0057] When the filter cartridge 32 is seriously clogged, the operator can open the rear cover door 6 to open the filter chamber 12. At this time, the filter cartridge 32 can be easily accessed for cleaning, replacement or maintenance, which greatly improves the efficiency and convenience of cleaning the filter cartridge 32. Preferably, a sealing strip 62 is provided at the connection between the rear cover door 6 and the box body 1, such as a rubber sealing strip, a silicone sealing strip, an inflatable sealing strip, etc. The sealing strip 62 seals the gap between the rear cover door 6 and the box body 1 to prevent material leakage or dust spillage.

[0058] See also Figure 1 and Figure 5 In this embodiment, the housing further includes a discharge door 5, and the bottom of the box body 1 is provided with the discharge door 5, which is used to open or close the bottom of the storage bin 11 and the filter bin 12, that is, the two bins can be discharged at the same time through one discharge door 5. Specifically, the structure of the discharge door 5 is a door panel that is hingedly mounted on the bottom of the box body 1 and can be opened and closed by driving, and the function is to open downward to discharge the storage bin 11 and the filter bin 12 synchronously.

[0059] When it is necessary to clean, maintain or replace the remaining material at the bottom of the storage bin 11 and / or the filter bin 12, the operator can start the opening and closing mechanism to open the discharge door 5. At this time, the material at the bottom of the storage bin 11 and / or the filter bin 12 can be discharged smoothly, which is convenient for cleaning and replacement. During normal operation of the shell, the discharge door 5 should remain closed. The closed discharge door 5 can ensure the sealing of the storage bin 11 and the filter bin 12 to prevent material leakage or dust spillover. It should be noted that a sealing strip 51, such as a rubber sealing strip, a silicone sealing strip, an inflatable sealing strip, etc., can be provided at the connection between the discharge door 5 and the box body 1. The sealing strip 51 seals the gap between the discharge door 5 and the box body 1 to prevent material leakage or dust spillover.

[0060] This integrated collecting device can be moved and operated synchronously in the train box. Compared with the structure in which the filtering bin 12 is separated from the storage bin 11, it not only does not occupy the space outside the train box, but the two bins can unload materials synchronously, which improves the working efficiency and reduces the labor cost.

[0061] See also Figure 1 and Figure 3 In this embodiment, the storage bin 11 and the filter bin 12 are arranged on the left and right, and the filter bin 12 includes an upper clean chamber 121, a lower ash chamber 122 and an air duct which are connected in sequence. The upper clean chamber 121 is located above the lower ash chamber 122, and the upper clean chamber 121 is provided with an air outlet 125 and a dust removal mechanism. The air duct includes an upper air duct 123 and a lower air duct 124. The upper air duct 123 is located above the lower air duct 124, and the upper air duct 123 is bent, such as a U-shape. The inlet of the upper air duct 123 is connected to the top of the storage bin 11, and the outlet of the upper air duct 123 is connected to the inlet of the lower air duct 124, and the outlet of the lower air duct 124 is connected to the inlet of the lower ash chamber 122.

[0062] The storage bin 11 is used to store external residual materials, and the filter bin 12 is responsible for filtering and collecting dust particles in the residual materials. The moving direction of the residual material collection and filtration is: filter bin 12 → upper air duct 123 → lower air duct 124 → lower ash chamber 122 → upper clean chamber 121.

[0063] When the remaining material in the cargo box enters the storage bin 11, the dust particles therein will enter the filter bin 12 along with the air flow. First, the dust particles enter the lower duct 124 through the upper air duct 123, and are guided to the lower ash chamber 122 in the lower air duct 124. In the lower ash chamber 122, the dust particles are collected, and the clean air enters the upper clean chamber 121 through the filter cartridge 32. When the dust removal mechanism 4 is working, the air blowing pipe 411 extends into the upper clean chamber 121 through the slot, and the clean gas released by the air blowing port 412 directly impacts the inner side of the filter cartridge 32, helping to remove the dust particles accumulated on the filter cartridge 32. The clean air is then discharged to the outside of the housing through the air outlet 125.

[0064] See also Figure 1 and Figure 3 In this embodiment, the filter mechanism 3 includes a filter screen 126, and the filter screen 126 is provided at the connection between the outlet of the air duct and the entrance of the ash lowering chamber 122, and the entrance of the ash lowering chamber 122 is located on the lower side wall of the ash lowering chamber 122. The filter screen 126 is made of a fine and durable material, such as a stainless steel mesh or a polymer material mesh, to ensure that it can effectively capture fine dust particles. This filter screen 126 is located at the connection between the outlet of the air duct and the entrance of the ash lowering chamber 122, and is intended to further filter and separate the dust particles entering the ash lowering chamber 122, ensuring that only fine dust is collected in the ash lowering chamber 122.

[0065] The upper air duct 123 can extend upward to the top of the upper clean room 121, then bend downward to connect to the lower air duct 124, so that the wind direction is first upward and then downward. The structure of the lower air duct 124 is to add parallel baffles on the wall of the filter bin 12 to form a channel, so that the wind direction is downward. The filter screen 126 is located at the lower part of the upper air duct 123, so that the wind can enter the lower ash chamber 122 through the holes, while the particle dust falls into the ash collecting groove at the bottom of the lower ash chamber 122 under the action of inertia.

[0066] See also Figure 1 and Figure 3 In this embodiment, a folding plate 7 is provided in the storage bin 11. The folding plate 7 is located on the upper side of the suction port 111 and is used to block the airflow entering from the suction port 111 and the upward movement of dust particles. The design of the folding plate 7 is to optimize the airflow and the movement path of dust particles in the storage bin 11, thereby improving the filtering effect and cleaning efficiency.

[0067] The folding plate 7 is usually made of a strong and corrosion-resistant material, such as a stainless steel plate or a polymer plastic plate, to ensure that it can withstand certain impacts and wear. The shape and size of the folding plate 7 are carefully designed to ensure that it can effectively block the airflow entering from the suction port 111 and the upward movement of dust particles.

[0068] See also Figure 1 and Figure 3 In the present embodiment, the suction mechanism 2 includes a fan 21 and a suction pipe 22. The fan 21 is connected to the air outlet 125 of the filter bin 12. The suction pipe 22 is located outside the storage bin 11 and is connected to the suction port 111 of the storage bin 11. The structure of the suction pipe 22 is generally a steel hose, which is used to contact the remaining material in the cargo box for suction. Specifically, the fan 21 can be installed on the outer wall of the box body 1, usually on the side or above the filter bin 12, which is convenient for installation and maintenance. The fan 21 serves as the power source of the suction mechanism 2, providing the necessary negative pressure environment so that the material in the cargo box can be sucked into the storage bin 11 by the suction pipe 22. In some embodiments, the suction mechanism 2 can use an air pump as the power source of the suction mechanism 2.

[0069] In this embodiment, the cargo box is a cargo box of a train, and the size of the shell is smaller than the size of the cargo box so that the shell can be placed in the cargo box. In some embodiments, the cargo box is a cargo box of a truck.

[0070] When there is residual material in the train cargo box that needs to be collected, the residual material collection device is hoisted into the cargo box of the train through the hoisting mechanism. The hoisting mechanism can use hoisting ropes, hoisting hooks, etc. to ensure that the device can be stably suspended inside the cargo box. After the device enters the cargo box, the suction mechanism 2 is started to suck the residual material and dust particles in the cargo box through the suction port 111. After these particles are sucked in, they are filtered and separated by the filtering mechanism 3, and the clean air is discharged through the air outlet 125, while the dust particles are collected in the box body 1. When the residual material in the cargo box is collected, the residual material collection device is hoisted out of the cargo box through the hoisting mechanism. Place the device in a suitable position, open the unloading door 5, and pour out the residual material in the storage bin 11. The design of the unloading door 5 should be easy to operate to ensure that the residual material can be discharged smoothly. After emptying the material, close the unloading door 5, and hoist the residual material collection device into the train cargo box again through the hoisting mechanism to prepare for the next round of residual material collection operations.

[0071] Working principle of cargo box residual material collection device:

[0072] Under the action of the fan 21, negative pressure is formed in the storage bin 11 and the filter bin 12, and suction is formed at the suction port 111. The suction force enables the suction pipe 22 connected to the suction port 111 to have adsorption force to adsorb the remaining materials in the train cargo box into the storage bin 11. After the material enters the storage bin 11, it falls downward under the action of the folding plate 7, and then the gas rises and enters the upper air duct 123. During the rising process of the gas (carrying dust particles), some heavier dust particles cannot rise into the upper air duct 123 due to their own weight, thus completing the first level of filtration.

[0073] The gas moves downward through the lower air duct 124 (also called the reversal duct). During the downward movement, some dust particles fall into the ash collecting trough at the bottom of the air duct and the lower ash chamber 122 due to inertia, while the gas passes through the filter screen 126 to the bottom of the filter cartridge 32, that is, the lower ash chamber 122, completing the second stage of filtration.

[0074] The gas continues to move upward, and is discharged from the air outlet 125 of the fan 21 after being filtered by the filter cartridge 32, completing the third level of filtration, filtering the dust from the gas discharged into the air, and making the gas discharged into the air environmentally friendly and pollution-free.

[0075] After the residual material adsorption is completed, the residual material collection device is lifted out of the cargo box of the train box. When the fan 21 is lifted out of the train box, the solenoid valve 42 in the dust removal mechanism 4 is opened through automatic electrical control, and only one solenoid valve 42 is opened at a time in sequence. Each time, the solenoid valve 42 is opened to back-blow and remove dust when the air pressure in the air bag 41 reaches a sufficient value. When the filter cartridge 32 is seriously blocked, the rear cover door 6 can be opened to manually clean the filter cartridge 32.

[0076] The collected materials and the dust collected by the filter system are discharged by opening the discharge door 5 at the bottom of the box body 1. After the materials are emptied, the discharge door 5 is closed and the device is hoisted back into the cargo box of the train to continue to repeat the collection operation of the remaining materials.

[0077] Beneficial effects of the cargo box residual material collection device:

[0078] Compact structure, scientific layout, and complete functions: the box body 1 is divided into two parts to form a storage bin 11 and a filter bin 12. The air duct structure designed in the filter bin 12 utilizes the effects of self-weight sedimentation and inertial force to perform the first and second level filtration of dust particles, so that the dust particle content in the gas before reaching the filter cartridge 32 is greatly reduced, which can effectively improve the filtration efficiency. The structural design of the filter cartridge 32 mounting frame 31 and the rear cover door 6 not only makes the filter cartridge 32 easy to load and unload and maintain, but the mounting frame 31 can also partition the filter bin 12 into a lower ash chamber 122 and an upper clean chamber 121. By opening the unloading door 5, the storage bin 11 and the filter bin 12 can be unloaded at the same time.

[0079] Automation and high efficiency: The dust removal mechanism 4 (also called back-blowing system) is used to control the high-pressure air to enter the air blowing pipe 411 for back-blowing through the solenoid valve 42. Therefore, the filter cartridge 32 can be back-blown synchronously through electrical automation control during the process of the residual material collection device being hoisted out of the train box, and there are 4 air outlets at the end of one air blowing pipe 411, and 4 filter cartridges can be back-blown at a time.
