Description

Technical Field

[0001] This utility model relates to the field of waste treatment technology, and in particular to a waste compaction spraying system and a waste compactor. Background Technology

[0002] A waste compactor is a mechanical device used to compress waste. It is divided into stationary waste compactors and mobile waste compactors. Mobile waste compactors are mainly used in places such as landfills. They can move like vehicles and travel on the waste through their own power system. They use compaction rollers to repeatedly crush the waste. For example, in large landfills, mobile waste compactors can compact waste while moving, improving the space utilization rate of the landfill.

[0003] When garbage compactors crush and compact garbage, they produce a very foul odor and attract many mosquitoes, often requiring the spraying of deodorizers and insecticides. Existing garbage compactor spraying systems consist of an iron medicine tank, steel pipes, and copper nozzles. An electric pump pumps the liquid medicine from the iron medicine tank to the copper nozzles, which then spray the liquid medicine onto the compaction rollers, thus disinfecting mosquitoes and deodorizing.

[0004] Existing pesticide spraying systems for waste compactors operate using on-off control, which cannot adjust the flow rate of the sprayed pesticide according to different working conditions. This can easily lead to pesticide waste or insufficient spraying. In addition, because the pesticide is corrosive, it can easily cause corrosion of iron tanks and steel pipes, resulting in rust and other substances that clog filter elements and electric pumps, causing the entire system to malfunction. Utility Model Content

[0005] To address the technical problems of existing waste compactor spraying systems mentioned above, such as the inability to adjust the spray flow rate, poor adaptability, and susceptibility to corrosion from the spraying liquid leading to system failure, this utility model provides a waste compactor spraying system and a waste compactor.

[0006] The technical solution of this utility model is as follows:

[0007] This utility model provides a waste compaction spraying system, including a chemical pump. The pump's inlet is sequentially connected to a filter and a plastic chemical tank. The pump's outlet is sequentially connected to a flow proportioning valve and a spraying pipe. The spraying pipe is rust-proof and has several nozzles spaced along its axial direction for spraying onto compaction rollers. Both the pump and the flow proportioning valve are connected to a control mechanism located in the driver's cab. The filter effectively filters impurities in the chemical solution, preventing impurities from clogging the nozzles or damaging the pump, ensuring stable operation of the spraying system. The plastic chemical tank is lightweight, easy to install and transport, and the chemical... With good stability and minimal reaction with pesticide solutions, the rust-preventive spray pipe can be used for extended periods in humid and corrosive waste treatment environments, extending its service life. The nozzles spray pesticide solution onto the compaction rollers, cleaning and disinfecting them during waste compaction, reducing waste residue and odor adhesion, improving the hygiene of the compaction operation, and also helping to extend the maintenance cycle of the compaction rollers. The control mechanism in the cab allows operators to easily monitor the spraying system at any time, adjusting the amount of pesticide solution sprayed according to different working conditions, saving pesticide solution, avoiding waste, or insufficient spraying.

[0008] Preferably, the control mechanism includes a spray switch and a multi-position switch. The spray switch has a standard spray position and multiple spray positions, which are respectively connected to the pesticide pump. The multiple spray positions are also connected to the flow proportional valve through the multi-position switch. The spray switch enables one-button start and stop of the spraying system, making it easy to operate. The switching function allows for flexible adjustment of the spraying state according to actual operational needs. The multi-position switch can adjust the flow rate, allowing for precise control of the spraying amount for different types of waste, compaction degrees, and hygiene requirements. This ensures cleaning and disinfection effects while avoiding pesticide waste and reducing operating costs. Furthermore, the multi-position switch, used in conjunction with the multiple spray positions of the spray switch, can prevent misoperation.

[0009] Preferably, the spray switch is a contact switch with a non-spraying position, a standard spraying position, and multiple spraying positions. The contact switch is easy to operate. The standard spraying position is suitable for routine garbage compaction operations, providing a stable and appropriate amount of spray to meet daily cleaning and disinfection needs. The multiple spraying positions are prepared for special situations, such as when encountering particularly dirty or odorous garbage, which can increase the amount of spray to enhance the cleaning effect and make the spraying system more adaptable.

[0010] Preferably, the multi-position switch is a point-contact switch, which is sensitive to operation. The operator can switch positions with a light touch. When operating in the cab, there is no need for large movements, which makes it easier to observe the work site without being distracted, reducing the risk of operational errors and improving work safety. In addition, it has a simple structure, high reliability, and low maintenance cost.

[0011] Preferably, the multi-position switch is a resistive rotary switch, which can realize continuous flow adjustment. Compared with the touch switch, the adjustment is more precise. It can accurately match the most suitable amount of spraying according to the subtle changes in the garbage, such as the humidity and composition ratio of the garbage, and further optimize the efficiency of the liquid use. Moreover, the rotary structure is more comfortable to hold, and it is easier for the operator to control the force and angle when adjusting.

[0012] Preferably, there are two spray pipes, which are arranged horizontally and coaxially. The two coaxial spray pipes can expand the spray coverage area, ensuring that all parts of the compaction roller are sprayed with liquid medicine evenly, avoiding spray dead corners, and making the cleaning and disinfection effect of the compaction roller more comprehensive and thorough, thereby improving the hygiene performance and working reliability of the entire waste compactor.

[0013] This utility model provides a garbage compactor, including: a cab, compaction rollers, a front frame, and a garbage compactor spraying system. The control mechanism is located in the cab, a plastic medicine tank is fixedly installed on the front frame, and a spray pipe is fixedly installed above the compaction rollers. Placing the control mechanism in the cab facilitates operator control and allows for easy adjustment of the spraying system during operation without the need to search for operating parts, thus improving operational smoothness. The plastic medicine tank, installed on the front frame, does not affect the overall structural stability of the compactor and facilitates the replenishment and maintenance of the pesticide solution. The spray pipe, fixed above the compaction rollers, ensures that the sprayed pesticide solution falls accurately onto the compaction rollers.

[0014] Preferably, the axis of the spray pipe is parallel to the axis of the compaction roller, which allows the sprayed liquid to be evenly distributed on the compaction roller, improving the cleaning and disinfection effect, while reducing splashing and waste of liquid, making the spraying process more efficient and energy-saving.

[0015] As can be seen from the above technical solutions, the advantages of this utility model are:

[0016] 1. The filter effectively filters impurities in the pesticide solution, preventing impurities from clogging the nozzles or damaging the pesticide pump, ensuring stable operation of the spraying system. The use of plastic pesticide tanks and rust-proof spray pipes effectively avoids pesticide corrosion and prevents rust contamination of the pesticide solution, thus extending the service life of the entire spraying system. The control mechanism in the cab allows operators to monitor the spraying operation of the system at any time, adjusting the amount of pesticide sprayed according to different working conditions, saving pesticide and avoiding waste or insufficient spraying.

[0017] 2. The spray switch has three positions, enabling one-button start / stop and switching of the spraying system. It is easy to operate and the switching function allows for flexible adjustment of the spraying status according to actual operation needs. The multi-position switch can adjust the flow rate, allowing for precise control of the spraying amount for different types of waste, compaction levels, and hygiene requirements. This ensures cleaning and disinfection effects while avoiding waste of pesticides and reducing operating costs. Furthermore, the multi-position switch, when used in conjunction with the multi-position spraying settings of the spray switch, can prevent misoperation. Attached Figure Description

[0023] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0024] Example 1

[0025] In a typical embodiment of this utility model, such as Figures 1-2As shown, a waste compaction spraying system is proposed, including: a plastic medicine tank 1, a filter 2, a medicine pump 3, a flow proportional valve 4, a spraying pipe 6, a nozzle 7, and a control mechanism. The plastic medicine tank 1 is made of rotational molding material, which can effectively avoid corrosion of the medicine and prevent contamination and system blockage. The filter 2 uses a polymer material filter element, which can filter large particles in the medicine to prevent foreign objects from entering the medicine pump 3. The inlet of the filter 2 is connected to the outlet of the plastic medicine tank 1 through a pipe, and the outlet of the filter 2 is connected to the inlet of the medicine pump 3 through a pipe. The filtered medicine enters the medicine pump 3, and the outlet of the medicine pump 3 is connected to the spraying pipe 6 through a pipe. The pipe connecting the medicine pump 3 and the spraying pipe 6... The road is also equipped with a flow proportional valve 4, which is an electrically controlled proportional valve that can adjust the flow rate of the sprayed liquid by changing the current to adapt to different working conditions. There are several nozzles 7, which are installed at intervals on the spray pipe 6 to spray the liquid in the spray pipe 6 evenly onto the compaction rollers of the garbage compactor. The nozzles 7 are all copper nozzles, and the spray pipe 6 is made of stainless steel to effectively avoid corrosion of the liquid and prevent rust from contaminating the liquid. The control mechanism is located in the cab of the garbage compactor. The control mechanism is connected to the pump 3 and the flow proportional valve 4 through wires to control the operation of the pump 3 and the flow proportional valve 4. All pipelines are flexible hoses 8.

[0026] It is understandable that other rust-proof pipes can also be used for the spray pipe 6, such as carbon steel lined with stainless steel composite pipe, nano polymer lined with stainless steel composite pipe, plastic pipe, etc. No further restrictions will be made here.

[0027] In this embodiment, there are two spray pipes 6, and several nozzles 7 are fixedly installed on each spray pipe 6 at intervals along its axial direction. Both spray pipes 6 are arranged laterally and coaxially. The axis of the spray pipe 6 is parallel to the axis of the compaction roller to ensure that the liquid is sprayed evenly onto the compaction roller. The two spray pipes 6 are connected to each other and to the pump 3 through hoses 8 and T-joints 5. The hoses 8 can effectively adjust the position of the two spray pipes 6 to adapt to the front frame of the garbage compactor.

[0028] The control mechanism includes a spray switch 9 and a multi-position switch 10. The spray switch 9 is a contact switch used for switching the entire system on and off. The multi-position switch 10 is a point-contact switch used to adjust the flow rate. Both the spray switch 9 and the multi-position switch 10 are located in the driver's cab of the garbage compactor. Figure 2As shown, the spray switch 9 includes a standard spray position 11 and a multi-position spray position 12. The standard spray position 11 and the multi-position spray position 12 are respectively connected to the pesticide pump 3. The multi-position spray position 12 is also connected to the flow proportional valve 4 through the multi-position switch 10. Thus, the spray switch 9 can be used to control the start, stop and switch of the spraying system, such as switching to the no-spray position (i.e., neither the standard spray position 11 nor the multi-position spray position 12 is closed), the standard spray position 11 or the multi-position spray position 12. The flow proportional valve 4 is a normally open type when the power is off. When the flow rate needs to be adjusted, it needs to be controlled by the multi-position switch 10.

[0029] It is understood that in other embodiments, the multi-position switch 10 can also be replaced by a resistive rotary switch, which can directly adjust the current value of the flow proportional valve 4, thereby controlling the spray flow rate.

[0030] The specific working principle is as follows:

[0031] The spray switch 9 has three positions: no spraying, standard spraying 11, and multi-spraying 12.

[0032] When the spray switch 9 is switched to the non-spraying position (i.e., neither the standard spraying position 11 nor the multi-spraying position 12 is closed), the pesticide pump 3 and the flow proportional valve 4 are not powered, and the entire spraying system does not work.

[0033] When the spray switch 9 is switched to the standard spraying position 11, the control pump 3 is powered on and works normally, the flow ratio valve 4 is de-powered and normally open, and the spraying system sprays the pesticide solution according to the standard spraying flow rate. It can achieve one-button spraying for standard spraying conditions, making it convenient and efficient to use.

[0034] When the spray switch 9 is switched to the multi-level spraying position 12, both the control pump 3 and the flow proportional valve 4 are energized. The pump 3 works normally. At this time, pressing the multi-level switch 10 adjusts the current of the flow proportional valve 4, and the flow rate of the flow proportional valve 4 changes to adjust the flow rate of the sprayed liquid proportionally, such as increasing or decreasing the liquid flow rate by 10%. This allows for adjustments based on different working conditions, such as the number of mosquitoes, making the operation more intelligent, saving liquid, and making it more economical.

[0035] Example 2

[0036] In a typical embodiment of this utility model, a garbage compactor is provided, including a cab, compaction rollers, and a front frame. The cab is located above the front of the garbage compactor, the compaction rollers are located at the bottom of the garbage compactor, and the front frame is located below the cab and in front of the compaction rollers. The cab and the compaction rollers are connected by the front frame. A plastic medicine tank 1 is fixedly installed on the front frame by bolts and a pressure plate. A spray pipe 6 is fixedly installed on a mounting seat above the compaction rollers to evenly spray the medicine onto the compaction rollers through a nozzle 7. The filter 2, the medicine pump 3, the flow proportional valve 4, the tee connector 5, and the spray pipe 6 are all connected by hoses 8. The hoses 8 are fixedly connected to the interfaces of each component by hose clamps.

[0037] In this embodiment, the filter 2, the medicine pump 3, and the flow proportional valve 4 are all fixedly installed on the front frame. It is understood that in other embodiments, the filter 2, the medicine pump 3, and the flow proportional valve 4 may also be fixedly installed in other places. No further restrictions are imposed here.

[0038] When the garbage compactor is working, the spray switch 9 is in the non-spraying position by default; when the spray switch 9 is set to the standard spraying position 11, the liquid can be sprayed at the standard flow rate.

[0039] When it is necessary to change the spray flow rate of the pesticide, the spray switch 9 is set to the multi-level spray position 11. At this time, the flow rate can be increased or decreased by adjusting the multi-level switch 10.

[0040] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
