Description

Technical Field

[0001] This utility model relates to the technical field of waste treatment equipment, specifically to the exhaust purification system of an integrated waste compression box. Background Technology

[0002] Currently, when integrated waste compactors are used in waste transfer stations, the compression chamber and body of the compactor are relatively enclosed. This enclosed space experiences backflow and disturbance during dumping, which can easily lead to waste fragments and high concentrations of odorous gases escaping from the disposal opening. This deteriorates the air quality and working environment of the waste transfer station, threatening the health of workers. Therefore, we propose an exhaust purification system for integrated waste compactors. Utility Model Content

[0003] The purpose of this invention is to provide an exhaust purification system for an integrated waste compression box to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The exhaust purification system of the integrated waste compression box includes a docking cover for connecting to the exhaust port of the integrated waste compression box, a negative pressure pipe connecting the docking cover, a negative pressure device connecting the negative pressure pipe, and a deodorization and purification device connected to the output end of the negative pressure device through a pipe. The negative pressure pipe includes a rigid pipe, a telescopic pipe connecting the rigid pipe and the docking cover, and a telescopic device 1 connecting the rigid pipe and the docking cover. The telescopic device 1 is used to drive the docking cover downward to dock with the exhaust port.

[0006] A further improvement is that the docking cover is equipped with a sensor group for detecting the position of the exhaust vent. When the sensor group detects that the docking cover corresponds to the exhaust vent, the telescopic device is controlled to move the docking cover downwards to dock with the exhaust vent.

[0007] A further improvement is that the docking cover is provided with an intercepting wire mesh component, the intercepting wire mesh component has a shaft in the middle, one end of the shaft extends to the top of the intercepting wire mesh component and is connected to an impeller driven to rotate by the incoming gas, and the other end is provided with a cleaning scraper for fitting against the end of the intercepting wire mesh component facing the exhaust port.

[0008] A further improvement is that the negative pressure pipeline is equipped with a detection sensor connected to an external controller, and one end of the shaft is also connected to the output end of a drive device located on the inner wall of the docking cover. When the detection sensor detects that the gas flow rate inside the negative pressure pipeline is lower than a preset threshold, the drive device drives the shaft to rotate.

[0009] A further improvement is that the shaft includes a sleeve fixedly inserted into the center of the intercepting wire mesh component, a docking shaft and a connector respectively inserted into both ends of the sleeve, the docking shaft and the connector are connected by a snap-fit ​​structure, and a limiting ring for fitting with the end of the sleeve is rotatably sleeved on both the docking shaft and the connector. The outer wall of the connector is provided with an external thread, and the inner wall of the cleaning scraper is provided with an internal thread adapted to the external thread.

[0010] A further improvement is that the sensor group is connected to an external controller, and the sensor group includes an infrared transmitter and receiver located on the outer wall of the docking cover, and a reflector located on the outer wall of the exhaust vent and cooperating with the infrared transmitter.

[0011] A further improvement is that a cover plate for closing the docking cover is connected to the bottom rotating shaft of the docking cover. The cover plate is driven to rotate by a driving component. When the sensor group detects that the docking cover corresponds to the exhaust port, the driving component drives the cover plate to open the docking cover.

[0012] A further improvement is that the sensor group also includes a laser rangefinder sensor disposed on the outer wall of the docking cover, and a reflector second disposed on the outer wall of the exhaust vent in cooperation with the laser rangefinder sensor.

[0013] A further improvement is that the docking cover and the exhaust vent are connected by a fastener. When the laser rangefinder detects that the distance between the docking cover and the exhaust vent reaches a threshold, the fastener causes the controller to control the fastener to fix the docking cover and the exhaust vent, and the telescopic device stops working.

[0014] A further improvement is that a baffle is attached to the end of the exhaust vent away from the docking cover, and the baffle is driven by a telescopic device on the integrated waste compression box to close or open the exhaust vent.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This exhaust and purification system uses a telescopic device to automatically connect the docking hood to the exhaust outlet. When the integrated garbage compression box is dumping garbage, the negative pressure device, negative pressure pipe and docking hood create a directional airflow during garbage dumping. In conjunction with the deodorization and purification equipment, it effectively suppresses garbage escape during the operation process and effectively purifies odorous gases, greatly reduces odor emissions, and significantly improves the working environment and air quality of the garbage transfer station.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see the appendix Figure 1-3 The exhaust purification system of the integrated waste compression box 1 includes a horn-shaped docking cover 3 (the exhaust port 2 is located at the top of the front end of the integrated waste compression box) for connecting to the exhaust port 2 on the integrated waste compression box 1, a negative pressure pipe 4 connected to the docking cover 3, a negative pressure device 5 (such as a centrifugal fan or a high-pressure vortex fan) connected to the negative pressure pipe 4, and a deodorization and purification device 6 connected to the output end of the negative pressure device 5 through a pipeline. The deodorization and purification device 6 includes, for example, a cyclone dust collector, a UV light deodorization device, etc. Furthermore, the inner wall of the docking cover 3 is embedded with a corrosion-resistant sealing ring (such as silicone or EPDM material) to ensure the airtightness between it and the exhaust port 2.

[0025] The negative pressure pipe 4 includes a rigid pipe 41 (such as stainless steel or UV-resistant PVC material), a telescopic pipe 42 (such as a corrugated hose) connecting the rigid pipe 41 and the docking cover 3, and a telescopic device 43 (such as an electric telescopic rod and a hydraulic cylinder) connecting the rigid pipe 41 and the docking cover 3. The docking cover 3 is equipped with a sensor group 18 for detecting the position of the exhaust port 2. When the sensor group 18 detects that the docking cover 3 corresponds to the exhaust port 2, it controls the telescopic device 43 to drive the docking cover 3 to move downward and dock with the exhaust port 2.

[0026] It should be noted that this exhaust purification system can be specifically installed above the integrated waste compression box 1 within the waste transfer station (as shown in the attached document). Figure 1 As shown), for example, it can be fixed by guide rails or hanging brackets to ensure coverage of the working area. When in use, the integrated garbage compression box 1 moves to the required position (detected by sensor group 18). After moving to the required position, the telescopic device 43 drives the docking cover 3 to move downward and dock with the exhaust port 2. Thus, when the integrated garbage compression box 1 dumps garbage, the exhaust purification system removes odor and improves the working environment of the garbage transfer station.

[0027] Preferably, the sensor group 18 in this embodiment is connected to an external controller (such as a PLC controller). The sensor group 18 includes an infrared transmitter and receiver disposed on the outer wall of the docking cover 3, and a reflector (made of high reflectivity PET material) disposed on the outer wall of the exhaust port 2 in conjunction with the infrared transmitter. Several sets of infrared transmitter and receiver and reflector can be set. When the exhaust port 2 approaches the docking cover 3, the light beam emitted by the infrared transmitter and receiver is detected by the reflector and then sent to the external controller. The external controller can calculate the horizontal offset between the docking cover 3 and the exhaust port 2 in real time and generate a correction command. The position is adjusted according to the correction command, such as the position of the integrated garbage compression box 1, until the exhaust port 2 and the docking cover 3 are directly aligned. Then the telescopic device 43 drives the docking cover 3 to move downward and dock with the exhaust port 2.

[0028] Preferably, in this embodiment, the bottom rotating shaft of the docking cover 3 is connected to a cover plate 15 for closing the docking cover 3. The cover plate 15 is driven to rotate by a driving component (e.g., a micro motor, the output end of which is connected to the shaft connecting the cover plate 15 and the docking cover 3). When the sensor group 18 detects that the docking cover 3 corresponds to the exhaust port 2, the driving component causes the cover plate 15 to open the docking cover 3. With this setting, when the docking cover 3 does not correspond to the exhaust port 2, the cover plate 15 can close the docking cover 3, making it difficult for external dust or insects to enter. When the docking cover 3 corresponds to the exhaust port 2, the cover plate 15 is opened under the action of the driving component, which does not affect the subsequent telescopic device 43 driving the docking cover 3 to move downward and dock with the exhaust port 2.

[0029] Preferably, in this embodiment, a baffle 19 is attached to the end of the exhaust vent 2 away from the docking cover 3. The baffle 19 is driven by a telescopic device 20 (e.g., an electric telescopic rod) on the integrated waste compression box 1 to close or open the exhaust vent 2. When the docking cover 3 is not docked with the exhaust vent 2, the exhaust vent 2 is closed by the baffle 19 to prevent rainwater or dust from entering and to prevent waste from leaking out of the integrated waste compression box 1. When the docking cover 3 is docked with the exhaust vent 2, the baffle 19 can be moved to open the exhaust vent 2 by controlling the telescopic device 20.

[0030] Preferably, this system can be used in conjunction with the power system of the integrated compression box. In actual situations, the tipping action of the integrated garbage compression box 1 can be monitored by the power system of the integrated garbage compression box 1. When the tipping box is lifted, this system will start automatically. Secondly, the operating power of the deodorization and purification equipment 6 in this system can be set to be positively correlated with the amount of garbage put in, and dynamically adjusted by a weight sensor. Furthermore, in the event of a system failure, an audible and visual alarm can be triggered and the exhaust port 2 baffle 19 can be automatically closed.

[0031] Example 2

[0032] Please see the appendix Figure 3-4 Based on Embodiment 1, the docking cover 3 of this embodiment is provided with an arc-shaped intercepting wire mesh 12 (for example, made of 304 stainless steel woven into a 60-mesh double-layer mesh structure). The intercepting wire mesh 12 can intercept garbage and particulate matter, and also effectively intercept moisture in the gas to achieve gas-liquid separation. The intercepting wire mesh 12 has a shaft in the middle. One end of the shaft extends above the intercepting wire mesh 12 and is connected to an impeller 13 driven to rotate by the incoming gas. The other end is provided with a cleaning scraper 10 for fitting against the end of the intercepting wire mesh 12 facing the exhaust port 2. With this arrangement, when the negative pressure device 5 is working and drawing in gas, the incoming gas drives the impeller 13 to rotate. The impeller 13 drives the cleaning scraper 10 to rotate and clean the intercepting wire mesh 12 to prevent blockage at the intercepting wire mesh 12 from affecting the exhaust stability.

[0033] Preferably, the negative pressure pipe 4 in this embodiment is equipped with a detection sensor 16 (such as a gas flow sensor) connected to an external controller. One end of the shaft is also connected to the output end of a drive device 14 (such as a micro motor; it should be noted that the selected micro motor is in an active state when it is not working) located on the inner wall of the docking cover 3. When the detection sensor 16 detects that the gas flow rate inside the negative pressure pipe 4 is lower than a preset threshold, the drive device 14 drives the shaft to rotate. When the blockage at the intercepting wire mesh 12 is severe, the gas flow rate entering the negative pressure pipe 4 is less than the preset threshold, and the drive device 14 actively drives the shaft to rotate to clean through the cleaning scraper 10, which can prevent the impeller 13 from failing and being unable to rotate for cleaning.

[0034] Preferably, the shaft portion of this embodiment includes a sleeve fixedly inserted into the center of the intercepting wire mesh component 12, and a docking shaft 7 and a connector 8 respectively inserted into both ends of the sleeve. The docking shaft 7 and the connector 8 are connected by a snap-fit ​​structure 9. The snap-fit ​​structure 9 is selected according to the actual situation and will not be described in detail here. Both the docking shaft 7 and the connector 8 are rotatably fitted with a limiting ring 11 for fitting with the end of the sleeve. The outer wall of the connector 8 is provided with an external thread, and the inner wall of the cleaning scraper 10 is provided with an internal thread that matches the external thread. With the above-mentioned arrangement, it is convenient to disassemble the connector 8 and replace the cleaning scraper 10 on the connector 8, and it is also convenient to replace the intercepting wire mesh component 12 or adjust the position of the cleaning scraper 10.

[0035] Example 3

[0036] Please see the appendix Figure 1-3 Based on Embodiment 1, the sensor group 18 in this embodiment also includes a laser range sensor disposed on the outer wall of the docking cover 3, and a reflector II disposed on the outer wall of the exhaust vent 2 in cooperation with the laser range sensor. The laser range sensor and the reflector II are used to detect the distance between the docking cover 3 and the exhaust vent 2.

[0037] Preferably, in this embodiment, the docking cover 3 and the exhaust port 2 are connected by a fastener 17. When the laser rangefinder detects that the distance between the docking cover 3 and the exhaust port 2 has reached a threshold, the fastener 17 causes the controller to control the fastener 17 to fix the docking cover 3 and the exhaust port 2, and the telescopic device 43 stops working. The fastener 17 is, for example, an electric latch or an electromagnetic adsorption structure (a permanent magnet ring on the outer wall of the exhaust port 2 and an electromagnetic ring embedded in the bottom of the docking cover 3), etc. In this way, the docking cover 3 is stably docked and locked downwards with the exhaust port 2.
