Method for inhibiting odor in garbage transfer workshop from escaping from driving roadway and odor-resistant structure

Abstract

The invention discloses a method for inhibiting odor in a garbage transfer workshop from escaping from a driving roadway and an odor-resistant structure. The odor-resistant structure comprises a flow-blocking inclined plate which is arranged above the edge part of a loading hopper and is used for blocking upwelling airflow at the edge part of the loading hopper, and a semi-closed space is formed below the flow-blocking inclined plate; the flow blocking inclined plate is used for guiding blocked upwelling airflow into the space to do vortex motion, and kinetic energy of the upwelling airflow is consumed through the vortex motion, so that the upwelling airflow is prevented from flowing to a driving roadway. When a garbage collecting vehicle dumps garbage into the loading hopper, upwelling airflow close to one side of the formed roadway is blocked through the flow blocking inclined plate, so that the airflow is guided to form vortex in the space below the flow blocking inclined plate, and the kinetic energy of the airflow is greatly consumed; therefore, the part of airflow can be effectively weakened from flowing into the driving roadway, and a good effect of preventing odor from escaping can be achieved.

Description

Technical Field

[0001] The invention relates to the technical field of odor prevention in a domestic waste transfer workshop, and in particular to a method and a device for suppressing odor escape from a domestic waste transfer workshop. Background Art

[0002] In the patent application number 2024113233130, entitled A method for suppressing odor in a garbage transfer workshop and a garbage transfer workshop, the applicant proposed a method for preventing odors in the garbage dumping isolation room and the driving lane from escaping from the lane entrance of the driving lane by setting a negative pressure suction device to extract the gas in the garbage dumping isolation room and making the airflow in the driving lane flow only in one direction from the lane entrance to the garbage dumping isolation room under the action of negative pressure. However, in the specific implementation, since a strong recoil airflow is generated when the garbage collection truck dumps the garbage into the loading hopper, and since the middle space of the garbage loading hopper is mainly occupied by the falling garbage flow during the garbage dumping process, the recoil airflow mainly surges upward from the space around the garbage loading hopper. The speed of the recoil airflow is high, which makes it easy for the airflow to rush into the driving lane; especially the upwelling airflow near the side of the driving lane, which is blocked by the upper cargo box and easily turns to rush into the driving lane, resulting in the problem of odor escaping; in addition, due to the large distance between the garbage collection truck and the wall of the driving lane, it also increases the difficulty of the negative pressure suction device to prevent the odor from escaping from the driving lane. Therefore, it is necessary to make further improvements based on the aforementioned patented technology to further reduce the possibility of odor escaping from the driving lane. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a method and an anti-odor structure for inhibiting the odor from escaping from the traffic lane of a garbage transfer workshop, so as to solve the technical problem that the backwash odor airflow generated by dumping garbage has a high velocity and the backwash odor airflow is easy to rush into the traffic lane and escape.

[0004] The method for suppressing the odor from the garbage transfer workshop from escaping from the driving lane of the present invention comprises arranging a baffle plate above the edge of the loading hopper for blocking the upwelling airflow at the edge of the loading hopper, forming a semi-enclosed space below the baffle plate, and guiding the blocked upwelling airflow into the space to perform eddy motion by utilizing the baffle plate, consuming the kinetic energy of the upwelling airflow through the eddy motion, thereby preventing the upwelling airflow from flowing toward the driving lane.

[0005] Further, the baffle plate is arranged above the front side of the loading hopper, or the baffle plate is arranged above the front side, the left side and the right side of the loading hopper, or the baffle plate is arranged above all sides of the loading hopper, and the front side of the loading hopper is the side adjacent to the end of the driving lane.

[0006] Furthermore, the method for suppressing the odor from the garbage transfer workshop from escaping from the driving lane also includes providing a negative pressure suction port in the space below the baffle ramp to suck the recoil airflow.

[0007] Furthermore, the method for suppressing the odor from the garbage transfer workshop from escaping from the driving lane also includes setting an upper rolling shutter plate that can be telescoped up and down at the top of the driving lane, setting a left rolling shutter door that can be telescoped left and right on the left side of the driving lane, and setting a right rolling shutter door that can be telescoped left and right on the right side of the driving lane. When the garbage collection truck dumps garbage into the garbage loading hopper in the driving lane, the upper rolling shutter door, the left rolling shutter door and the right rolling shutter door are opened, so that the three rolling shutter doors are close to or in contact with the upper side, left side and right side of the cargo box respectively, so as to prevent the odor from flowing from the passage between the cargo box and the wall of the driving lane toward the exit of the driving lane.

[0008] Furthermore, negative pressure suction pipes are respectively arranged next to the matching position of the upper rolling shutter door and the cargo box, next to the matching position of the left rolling shutter door and the cargo box, and next to the matching position of the right rolling shutter door and the cargo box. Air is sucked through the negative pressure suction pipes to prevent odor from escaping from the gaps at the matching positions of each rolling shutter door and the cargo box.

[0009] The present invention also discloses an anti-odor structure according to the above-mentioned method of suppressing the escape of odor from the garbage transfer workshop from the driving lane, which includes a baffle plate arranged above the edge of the loading funnel, the baffle plate is arranged above the front side of the loading funnel, or the baffle plate is arranged above the front side, the left side and the right side of the loading funnel, or the baffle plate is arranged above the four sides of the loading funnel, and the front side of the loading funnel is the side adjacent to the end of the driving lane; a semi-enclosed space is formed below the baffle plate for the airflow gushing out from the edge of the loading funnel to enter and perform vortex motion.

[0010] Furthermore, the deodorizing structure also includes a negative pressure air inlet arranged in the space below the baffle inclined plate.

[0011] Furthermore, the upper end of the baffle plate is fixedly mounted in a hinged manner.

[0012] Furthermore, the deodorizing structure also includes an upper shutter plate arranged at the top of the driving lane, a left shutter door arranged on the left side of the driving lane, and a right shutter door arranged on the right side of the driving lane.

[0013] Furthermore, the upper rolling shutter plate is arranged to be staggered with the left rolling shutter door and the right rolling shutter door, and the staggered distance is within 15 cm.

[0014] Beneficial effects of the present invention:

[0015] 1. The method and anti-odor structure of the present invention for inhibiting the odor from escaping from the driving lane in the garbage transfer workshop. When the garbage collection truck dumps garbage into the loading hopper, the airflow rising from the edge of the loading hopper is blocked by the baffle plate. The baffle plate guides the rising airflow to form a vortex in the space below the baffle plate, thereby greatly consuming the kinetic energy of the part of the rising airflow, and further effectively reducing the ability of the part of the airflow to flow into the driving lane, especially better preventing the rising airflow close to one side of the driving lane from rushing into the driving lane, which can play a good effect in preventing the odor from escaping.

The negative pressure suction device in the garbage dumping isolation room can better prevent the odor from escaping from the driving lane. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Embodiment 1: In this embodiment, the method for suppressing the odor from the garbage transfer workshop from escaping from the driving lane includes setting a baffle plate 2 above the edge of the loading hopper 1 for blocking the upwelling airflow at the edge of the loading hopper, forming a semi-enclosed space 3 below the baffle plate, and guiding the blocked upwelling airflow to enter the space to perform eddy motion by utilizing the baffle plate, consuming the kinetic energy of the upwelling airflow through the eddy motion, thereby preventing the upwelling air from flowing toward the driving lane 4.

[0021] In a specific implementation, the baffle plate can be arranged only on the front side of the loading hopper, which is the side close to the end of the driving lane. Alternatively, the baffle plate can be arranged on the front side, the left side and the right side of the loading hopper, or on all four sides of the loading hopper.

[0022] If the baffle plate 2 is not provided, since the airflow rising from the loading hopper 1 has a high velocity, the rising airflow near the side of the garbage truck lane 4 is blocked by the upper cargo box, and it is easy to turn and flow into the space between the lower part of the cargo box and the bottom of the driving lane, and then rush to the entrance of the driving lane through the space. Even if there is a negative pressure suction port 7 in the dumping isolation room 6 to suck the odor in the dumping isolation room 6, it is difficult to prevent the escape of this part of the airflow. In this embodiment, the baffle plate 2 is provided to block the airflow rising from the edge of the garbage loading hopper, and guide this part of the airflow to form a vortex in the space below the baffle plate, thereby greatly consuming the kinetic energy of this part of the airflow, and then effectively weakening the ability of this part of the airflow to flow into the driving lane, especially better preventing the rising airflow near the side of the driving lane from rushing into the driving lane, which is conducive to the negative pressure suction device to suck away this part of the airflow, and can play a good role in preventing the odor from escaping.

[0023] As an improvement to the above embodiment, the method for inhibiting the odor from the garbage transfer workshop from escaping from the driving lane also includes providing a negative pressure suction port 7 in the lower space of the baffle ramp to suck the recoil airflow. This improvement can further speed up the extraction of the recoil odor airflow, which is helpful to prevent it from flowing into the driving lane.

[0024] As an improvement to the above embodiment, the method for inhibiting the odor from the garbage transfer workshop from escaping from the driving lane also includes setting an upper shutter plate 8 that can be extended up and down on the top of the driving lane 4, setting a left shutter door 9 that can be extended left and right on the left side of the driving lane, and setting a right shutter door 10 that can be extended left and right on the right side of the driving lane. When the garbage collection truck dumps garbage into the garbage loading hopper in the driving lane, the upper shutter door, the left shutter door and the right shutter door are opened, so that the three shutter doors are close to or in contact with the upper side, the left side and the right side of the cargo box respectively, so as to prevent the odor from flowing from the channel formed between the cargo box and the wall of the driving lane to the exit of the driving lane. By setting the upper shutter door, the left shutter door and the right shutter door to prevent the odor from flowing from the channel formed between the cargo box and the wall of the driving lane to the exit of the driving lane, the path for the odor to enter the driving lane is greatly reduced, and the probability of the odor escaping is greatly reduced.

[0025] As an improvement on the above embodiment, negative pressure suction pipes 11 are respectively arranged beside the matching position of the upper rolling shutter door and the cargo box, beside the matching position of the left rolling shutter door and the cargo box, and beside the matching position of the right rolling shutter door and the cargo box. A plurality of air inlet holes are evenly distributed on the negative pressure suction pipe 11. Negative pressure suction is used to prevent odor from escaping from the gaps at the matching positions of the rolling shutter doors and the cargo box.

[0026] Embodiment 2: According to the method of suppressing the odor of the garbage transfer workshop from escaping from the driving lane described in the above embodiment, the anti-odor structure includes a baffle plate 2 arranged above the edge of the loading hopper 1, and the baffle plate is arranged above the front side of the loading hopper, and the front side of the loading hopper is the side adjacent to the end of the driving lane. Of course, in different embodiments, the baffle plate can also be arranged above the front side, the left side, and the right side of the loading hopper, or the baffle plate can be arranged above the four sides of the loading hopper, and a semi-enclosed space 3 is formed below the baffle plate for the airflow gushing from the edge of the loading hopper to enter and perform vortex motion.

[0027] In this embodiment, the upper end of the baffle plate is fixedly installed in a hinged manner, and the upper end of the baffle plate can be directly hinged on the wall of the dumping isolation room 6; or a transverse connecting plate 12 can be arranged on the wall of the dumping isolation room 6, and the upper end of the baffle plate is hinged on the transverse connecting plate 12. The hinged installation allows the cleaning staff to flip the baffle plate upwards during cleaning, so as to facilitate cleaning of the space below the baffle plate.

[0028] As an improvement to the above-mentioned deodorizing structure, the deodorizing structure further comprises a negative pressure air inlet 7 arranged in the space below the baffle inclined plate.

[0029] As an improvement to the above-mentioned odor-proof structure, the odor-proof structure further includes an upper shutter plate 8 arranged at the top of the driving lane, a left shutter door 9 arranged at the left side of the driving lane, and a right shutter door 10 arranged at the right side of the driving lane. In this embodiment, the upper shutter plate is staggered with the left shutter door and the right shutter door, respectively, so that interference between the movement trajectories of the shutter doors can be avoided, and the staggered distance is within 15 cm, so that the path of gas passage can be reduced, which is conducive to preventing the escape of odor.

[0030] As an improvement on the above embodiment, the anti-odor structure also includes a negative pressure suction pipe 11 which is respectively arranged next to the matching position of the upper rolling shutter door and the cargo box, next to the matching position of the left rolling shutter door and the cargo box, and next to the matching position of the right rolling shutter door and the cargo box. A plurality of air inlet holes are evenly distributed on the negative pressure suction pipe 11. Air is sucked through the negative pressure suction pipe to prevent odor from escaping from the gaps at the matching positions of each rolling shutter door and the cargo box.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
