Description

Technical Field

[0001] This invention belongs to the field of environmental protection technology, and specifically relates to a telescopic and sealed odor gas treatment device and method. Background Technology

[0002] In the current treatment of odorous gases, gas filtration equipment is often used.

[0003] A search revealed that Chinese Patent Publication No. CN221309920U, authorized on July 12, 2024, discloses an easy-to-clean odor gas treatment device, including a body. A filter tube is fixedly installed on the side end of the body, and a connecting pipe is fixedly installed on the side end of the filter tube. An upper filter tube is fixedly installed on the upper end of the filter tube. The upper end of the filter tube has a first slide rail. The user first rotates a first magnetic block above the upper filter tube, then pulls the rope above the first filter screen upwards, moving the entire first filter screen assembly upwards above the upper filter tube. Simultaneously, a rubber base plate below the first filter screen seals the top of a second slide rail. Both the first and second slide rails have concave tops to block the rubber base plate. By designing the rubber base plate and rubber top plate to seal with the first and second slide rails, the airtightness of the first or second filter screen during replacement is ensured, preventing odor gas leakage.

[0004] However, the equipment still has the following drawbacks: although it can ensure the airtightness of the first or second filter screen during replacement to prevent the leakage of odorous gases, it cannot form a closed space during the unloading process of garbage trucks, which can easily lead to the leakage of odorous gases and is not conducive to treatment.

[0015] A method for treating odorous gases using a telescopic, sealed type device includes the following steps.

[0016] The telescopic sealing component drives the tarpaulin component during the telescopic process, allowing garbage trucks of different lengths to be fitted inside the tarpaulin component, thus keeping the garbage truck in a sealed state during unloading.

[0017] After connecting the disinfectant storage tank to the three-way valve, disinfectant is evenly sprayed inside the tarpaulin assembly, reducing the probability of bacteria growth in garbage in the enclosed space.

[0018] After the negative pressure deodorization device is connected to the three-way valve, the gas inside the tarpaulin assembly is adsorbed into the negative pressure deodorization device, which further reduces the malodorous gas during the unloading process.

[0019] The passive packing assembly can adaptively close the garbage placed into the garbage building, allowing the garbage to enter the container for centralized gas treatment.

[0020] The beneficial effects of this invention are:

[0021] 1. The telescopic sealing component moves the tarpaulin component during its extension and retraction, allowing garbage trucks of different lengths to be fitted inside the tarpaulin component. This keeps the garbage trucks in a sealed state during unloading. After the disinfectant storage tank is connected to the three-way valve, disinfectant is evenly sprayed inside the tarpaulin component, reducing the probability of bacteria growth in the sealed space. After the negative pressure deodorization device is connected to the three-way valve, the gas inside the tarpaulin component is adsorbed into the negative pressure deodorization device, further reducing odorous gases during unloading. The passive packing component can adaptively close the garbage entering the garbage building, allowing the garbage to enter the container for centralized gas treatment.

[0022] 2. The output end of the first electric telescopic rod pushes the middle part of the first cross arm, and the output end of the second electric telescopic rod pushes the middle part of the second cross arm, so that the first cross arm and the second cross arm drive the tarpaulin assembly to adjust to different lengths during the horizontal extension and retraction process, so as to meet the closed unloading state of different garbage trucks.

[0023] 3. Several sets of telescopic tubes can move synchronously with the extension of the tarpaulin assembly, so that the several sets of telescopic tubes are at different lengths. When the output end of the first motor drives the second gear to rotate, the several sets of telescopic tubes rotate synchronously. When disinfectant is injected into the telescopic tubes, the disinfectant can be evenly sprayed to different positions in the sealed space using several sets of first through holes. When negative pressure is formed in the telescopic tubes, the range of adsorption of malodorous gases in the sealed space can be expanded using several sets of first through holes.

[0024] 4. When tap water is injected through one end of the bend, the internal water pump pressurizes the tap water, causing it to spray downwards through several sets of second through holes to wash the garbage truck hopper after unloading. Simultaneously, the second motor drives the fourth gear to rotate, causing the second through holes at the bottom of the bend to swing back and forth at different positions on the top of the garbage truck hopper, thus expanding the washing range after unloading. After washing, an air pump continuously injects gas into the bend. When the water pump is not working, it can seal the other end of the bend to maintain the air pressure inside, allowing the high-pressure gas to be discharged through several sets of second through holes. This is used to dry the ground in the enclosed space after the garbage truck has been removed, thus improving the environment for gas treatment.

[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides a telescopic sealing type odor gas treatment device, including an assembly plate 3 and a telescopic sealing component 7; for example, such as... Figure 1 and Figure 2 As shown.

[0037] The telescopic sealing component 7 is connected to one side wall of the assembly plate 3. The outer wall of the assembly plate 3 is also provided with a three-way valve 4, a negative pressure deodorization device 5, and a disinfectant storage tank 6. The negative pressure deodorization device 5 and the disinfectant storage tank 6 are both connected to the three-way valve 4. The bottom end of the three-way valve 4 is connected to the telescopic sealing component 7. A tarpaulin component 8 is sleeved on the telescopic sealing component 7. A garbage building 1 is provided on the other side wall of the assembly plate 3. A garbage building door is opened on one side wall of the garbage building 1, and a passive filling component 2 is provided inside the garbage building door.

[0038] Specifically, during the telescopic sealing component 7, the tarpaulin component 8 is driven to extend and retract, allowing garbage trucks of different lengths to be fitted inside the tarpaulin component 8, thus keeping the garbage trucks in a sealed state during unloading. After the disinfectant storage tank 6 is connected to the three-way valve 4, disinfectant is evenly sprayed inside the tarpaulin component 8, reducing the probability of bacteria growth in the garbage in the sealed space. Then, after the negative pressure deodorization device 5 is connected to the three-way valve 4, the gas inside the tarpaulin component 8 is adsorbed into the negative pressure deodorization device 5, further reducing the odor during unloading. Finally, the passive packing component 2 can adaptively close the garbage put into the garbage building 1, allowing the garbage to enter the container for centralized gas treatment.

[0039] The passive packing assembly 2 includes a packing frame 21; for example, such as Figure 3 As shown.

[0040] The packing frame 21 has a U-shaped structure, and a load-bearing plate 22 is rotatably connected to the top of the inner wall of the packing frame 21. A seepage-proof plate 23 is also rotatably connected to the bottom of the inner wall of the packing frame 21. A shaft pin 24 is provided at the connection between the load-bearing plate 22 and the seepage-proof plate 23. A torsion spring is provided on the shaft pin 24. A pressure sensor is installed on the top of the load-bearing plate 22.

[0041] Specifically, the load-bearing plate 22 and the impermeable plate 23 are rotatably connected to the inner wall of the filling frame 21 by the axle pins 24 on both sides. The torsion springs set on the axle pins 24 cause the load-bearing plate 22 and the impermeable plate 23 to slowly rotate when they are pressed against by the garbage truck's bucket, forming a feeding port at the connection between the load-bearing plate 22 and the impermeable plate 23. When the garbage truck moves forward, the pressure on the load-bearing plate 22 and the impermeable plate 23 is released, and the tension of the torsion springs gradually closes the feeding port formed by the load-bearing plate 22 and the impermeable plate 23, so that the garbage after being put in is in a sealed state.

[0042] The telescopic sealing assembly 7 includes a main pipe 71; for example, such as Figure 4 As shown.

[0043] The main pipe 71 has a fan-shaped annular structure and is fixedly connected to one side wall of the assembly plate 3. Several sets of branch pipes 72 are rotatably connected to one side wall of the main pipe 71, and the several sets of branch pipes 72 are interconnected with the main pipe 71. Each set of branch pipes 72 is provided with a first gear 73, and a second gear 74 is meshed with the bottom of the first gear 73. The output end of a first motor 75 is drivenly connected to one side of the second gear 74, and the side of the first motor 75 away from the output end is fixedly connected to the outer wall of the assembly plate 3. The other end of each set of branch pipes 72 is provided with a telescopic pipe 76, and several sets of first through holes 77 are opened on the outer wall of the telescopic pipe 76. The bottom of each set of telescopic pipes 76 is provided with a telescopic mechanism 78, one end of the telescopic mechanism 78 is connected to the assembly plate 3, and the other end of the telescopic mechanism 78 is connected to an isolation mechanism 79.

[0044] The telescopic mechanism 78 includes a first cross arm 781, a second cross arm 784, and a bend 7811; for example, as shown... Figure 5 As shown.

[0045] Two sets of first hinge seats 782 are rotatably connected to one side of the first cross arm 781. One set of first hinge seats 782 is drivenly connected to the middle of the first cross arm 781 via a first electric telescopic rod 783. A first roller 787 is rotatably connected to the bottom of the connection between the first cross arm 781 and the second cross arm 784. A central shaft 785 is rotatably connected to the top of the connection between the first cross arm 781 and the second cross arm 784. A second electric telescopic rod 786 is drivenly connected to the middle of the second cross arm 784 via the central shaft 785. A second hinge seat 788 is rotatably connected to one side of the top of the second cross arm 784. One end of the central shaft 785 is fixedly connected to... A third gear 789 is connected to a fourth gear 7810 on one side. A second motor is connected to one side of the fourth gear 7810. The side of the second motor away from the output end is fixedly connected to the outer wall of the second cross arm 784. One end of the bent tube 7811 is embedded in the central shaft 785. Several sets of second through holes 7812 are opened at the bottom of the bent tube 7811. An air pump 7813 is provided at one end of the bent tube 7811. The other end of the bent tube 7811 is open. A water hose is connected to the opening of the bent tube 7811. A water pump is provided at the opening of the water hose and the opening of the bent tube 7811.

[0046] The isolation mechanism 79 includes an isolation frame 791; for example, such as Figure 6 As shown.

[0047] The bottom of the isolation frame 791 is provided with an installation groove 792, and a roller shutter door 793 is provided inside the installation groove 792. The bottom two sides of the isolation frame 791 are provided with second rollers 794. An air curtain machine 795 is installed on one side wall of the isolation frame 791. The outer wall of the isolation frame 791 and the side near the air curtain machine 795 are fixedly connected to the second hinge seat 788.

[0048] Specifically, the output end of the first electric telescopic rod 783 pushes the middle part of the first cross arm 781, and the output end of the second electric telescopic rod 786 pushes the middle part of the second cross arm 784, so that the first cross arm 781 and the second cross arm 784 drive the tarpaulin assembly 8 to adjust to different lengths during the horizontal telescopic process, so as to meet the closed unloading state of different garbage trucks.

[0049] The several sets of telescopic tubes 76 can move synchronously with the extension of the tarpaulin assembly 8, so that the several sets of telescopic tubes 76 are at different lengths. During the process of the second gear 74 being driven to rotate by the output end of the first motor 75, the several sets of telescopic tubes 76 rotate synchronously. When disinfectant is injected into the telescopic tubes 76, the several sets of first through holes 77 can be used to spray the disinfectant evenly to different positions in the enclosed space. When a negative pressure is formed in the telescopic tubes 76, the several sets of first through holes 77 can be used to expand the range of adsorption of malodorous gases in the enclosed space.

[0050] When tap water is injected into one end of the bend 7811, the internal water pump pressurizes the tap water, causing it to spray downwards through several sets of second through holes 7812 to wash the garbage truck hopper after unloading. Simultaneously, the second motor drives the fourth gear 7810 to rotate, causing the second through holes 7812 at the bottom of the bend 7811 to swing back and forth at different positions on the top of the garbage truck hopper, thereby expanding the washing range of the hopper after unloading. After washing, the air pump 7813 continuously injects gas into the bend 7811. When the water pump is not working, it can seal the other end of the bend 7811 to maintain the air pressure inside the bend 7811, allowing the high-pressure gas to be discharged through several sets of second through holes 7812. This is used to air dry the hopper after washing and the ground in the enclosed space after the garbage truck is removed, thus washing the ground environment and quickly drying the hopper.

[0051] The opening of the roller shutter door 793 facilitates the entry of garbage trucks, and the opening of the air curtain machine 795 is used to prevent the risk of malodorous gas leakage after the roller shutter door 793 is opened.

[0052] The tarpaulin assembly 8 includes a tarpaulin layer 81; for example, such as Figure 7 As shown.

[0053] The top side of the tarpaulin layer 81 is provided with a pipe pre-reserved hole 82, and the other side of the inner wall of the tarpaulin layer 81 is provided with a sealing layer 83, and the sealing layer 83 is fixedly connected to one end of several sets of telescopic pipes 76.

[0054] The working principle of the telescopic sealed odor gas treatment device proposed in this embodiment of the invention is as follows:

[0055] The opening of the roller shutter door 793 facilitates the entry of garbage trucks, while the opening of the air curtain machine 795 is used to prevent the risk of malodorous gas leakage after the roller shutter door 793 is opened.

[0056] The output end of the first electric telescopic rod 783 pushes the middle part of the first cross arm 781, and the output end of the second electric telescopic rod 786 pushes the middle part of the second cross arm 784, so that the first cross arm 781 and the second cross arm 784 drive the tarpaulin assembly 8 to adjust to different lengths during the horizontal extension and retraction process, so as to meet the closed unloading state of different garbage trucks.

[0057] Several sets of telescopic tubes 76 can move synchronously with the extension of the tarpaulin assembly 8, so that the several sets of telescopic tubes 76 are at different lengths. During the process of the second gear 74 being driven to rotate by the output end of the first motor 75, the several sets of telescopic tubes 76 rotate synchronously. When disinfectant is injected into the telescopic tubes 76, the disinfectant can be evenly sprayed to different positions in the enclosed space using several sets of first through holes 77. When a negative pressure is formed in the telescopic tubes 76, the range of adsorption of malodorous gases in the enclosed space can be expanded using several sets of first through holes 77.

[0058] The load-bearing plate 22 and the impermeable plate 23 are rotatably connected to the inner wall of the filling frame 21 by the axle pins 24 on both sides. The torsion springs set on the axle pins 24 cause the load-bearing plate 22 and the impermeable plate 23 to slowly rotate when they are pressed against by the garbage truck's bucket, forming a feeding port at the connection between the load-bearing plate 22 and the impermeable plate 23. When the garbage truck moves forward, the pressure on the load-bearing plate 22 and the impermeable plate 23 is released. The tension of the torsion springs causes the load-bearing plate 22 and the impermeable plate 23 to gradually return to their original position, closing the feeding port and keeping the garbage in a sealed state after it is put in.

[0059] When tap water is injected through one end of the bend 7811, the internal water pump pressurizes the tap water, causing it to spray downwards through several sets of second through holes 7812 to wash the garbage truck hopper after unloading. Simultaneously, the second motor drives the fourth gear 7810 to rotate, causing the second through holes 7812 at the bottom of the bend 7811 to swing back and forth at different positions on the top of the garbage truck hopper, thereby expanding the washing range of the hopper after unloading. After washing, the air pump 7813 continuously injects gas into the bend 7811. When the water pump is not working, it can seal the other end of the bend 7811 to maintain the air pressure inside the bend 7811, allowing the high-pressure gas to be discharged through several sets of second through holes 7812. This is used to air dry the hopper after washing and the ground in the enclosed space after the garbage truck is removed, thus washing the ground environment and quickly drying the hopper.

[0060] Based on the aforementioned telescopic sealed odor gas treatment device, this embodiment of the invention also provides a treatment method using the telescopic sealed odor gas treatment device, comprising the following steps.

[0061] The telescopic sealing component drives the tarpaulin component during the telescopic process, allowing garbage trucks of different lengths to be fitted inside the tarpaulin component, thus keeping the garbage truck in a sealed state during unloading.

[0062] After connecting the disinfectant storage tank to the three-way valve, disinfectant is evenly sprayed inside the tarpaulin assembly, reducing the probability of bacteria growth in garbage in the enclosed space.

[0063] After the negative pressure deodorization device is connected to the three-way valve, the gas inside the tarpaulin assembly is adsorbed into the negative pressure deodorization device, which further reduces the malodorous gas during the unloading process.

[0064] The passive packing assembly can adaptively close the garbage placed into the garbage building, allowing the garbage to enter the container for centralized gas treatment.

[0065] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.

4. A method for treating odorous gases using the telescopic sealed odor treatment device according to any one of claims 1-3, characterized in that: The governance method includes: The telescopic sealing component drives the tarpaulin component during the telescopic process, allowing garbage trucks of different lengths to be fitted inside the tarpaulin component, thus keeping the garbage truck in a sealed state during unloading. After connecting the disinfectant storage tank to the three-way valve, disinfectant is evenly sprayed inside the tarpaulin assembly, reducing the probability of bacteria growth in garbage in the enclosed space. After the negative pressure deodorization device is connected to the three-way valve, the gas inside the tarpaulin assembly is adsorbed into the negative pressure deodorization device, which further reduces the malodorous gas during the unloading process. The passive packing assembly can adaptively close the garbage placed into the garbage building, allowing the garbage to enter the container for centralized gas treatment.
