Description

Technical Field

[0001] This invention relates to the field of waste incineration, and more particularly to a waste incinerator that is easy to clean. Background Technology

[0002] In the waste treatment process, the incinerator is one of the key pieces of equipment. After long-term operation, traditional incinerators are prone to accumulating combustion residues (such as ash, unburned materials, etc.) at the bottom. This not only affects the combustion efficiency and heat transfer effect in the furnace, but the residues may also contain corrosive or harmful components. Long-term accumulation will accelerate the wear and corrosion of the furnace bottom structure and refractory materials, thereby damaging the furnace body and shortening the service life of the equipment.

[0003] In the early stages, the cleaning of ash from waste incinerators relied mainly on manual, periodic shutdowns for cleaning, which involved harsh working conditions, high labor intensity, and low efficiency. With the development of automation technology, semi-automatic or automatic ash cleaning devices have gradually emerged. For example, Chinese patent CN219624493U discloses a furnace bottom structure for a tungsten-molybdenum rod forging heating furnace, including a furnace body. The bottom surface of the furnace body is connected to a collection component that automatically collects ash and slag, enabling centralized collection of solid ash and slag generated during incineration. Operators only need to remove and empty the collection box after a certain amount of ash has accumulated, reducing the burden of manual cleaning.

[0004] Regarding the aforementioned technologies, in actual operation, operators still need to wait for the residue in the collection bins to accumulate to a certain amount before centralized cleaning, resulting in long cleaning cycles and untimely residue removal, which may affect the continuity of incineration and the operating efficiency of the equipment. Therefore, it is necessary to propose a new waste incinerator structure that can quickly clean residue to further improve the timeliness of residue treatment and overall operating efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a waste incinerator that is easy to clean.

[0006] This invention provides a waste incinerator that is easy to clean, and adopts the following technical solution:

[0007] A waste incinerator that is easy to clean includes a furnace body and a heater installed inside the furnace body. The furnace body has a feed inlet and a discharge outlet at both ends, and a cleaning outlet on both sides of the furnace body. The cleaning outlets of the furnace body are located at the bottom of the furnace body and are arranged opposite to each other. Each cleaning outlet of the furnace body is equipped with a cleaning device for quickly removing residue remaining at the bottom of the furnace body.

[0008] By adopting the above technical solution, when it is necessary to clean the residue, the residue can be cleaned from two opposite cleaning ports, which effectively improves the cleaning efficiency, avoids the accumulation of residue at the bottom of the furnace affecting the heating effect, reduces damage to the heating furnace, extends its service life, and prevents the residue from contaminating the heated metal.

[0009] Optionally, the two cleaning ports, the furnace inlet, and the outlet are all hinged with closed doors to meet the temperature requirements of the forging process and reduce heat loss.

[0010] By adopting the above technical solution, when tungsten and molybdenum forging is required, the setting of the closed door can slow down heat loss, thereby meeting the temperature requirements of forging; in the non-forging state, when the staff opens the closed door, the heat will dissipate from the opening, thereby achieving rapid heat dissipation of the heating furnace.

[0011] Optionally, the cleaning component includes a scraper, which is vertically installed inside the furnace body and movably connected to the furnace body. The scraper is positioned near the center of the furnace body and extends along the length of the furnace body. Two traction rods are provided on the side of the scraper near the cleaning port of the furnace body. The two traction rods are horizontally positioned at both ends of the scraper and are perpendicular to the scraper. Pull rods are provided on the outer side of the cleaning port of the furnace body. The two ends of the pull rods are fixedly connected to the ends of the two traction rods away from the scraper. A glove is fixedly connected to each pull rod and is worn on the outside of the pull rod.

[0012] By adopting the above technical solution, when it is necessary to clean the residue at the bottom of the furnace, the staff pulls the lever, which moves the traction rod, thereby moving the scraper to remove the residue inside the furnace. The gloves increase the friction between the hand and the lever, making it easier for people to pull the lever and pull out the scraper, thus completing the cleaning of the residue.

[0013] Optionally, the inner wall of the furnace body is provided with two U-shaped grooves, which are connected and arranged opposite to each other. Both ends of the scraper are provided with limiting blocks, which are slidably connected in the U-shaped grooves of the furnace body. When it is necessary to clean the residue in the furnace body, the limiting blocks slide at the lower end of the two U-shaped grooves; when it is necessary to reset the scraper, the limiting blocks slide at the upper end of the two U-shaped grooves.

[0014] By adopting the above technical solution, when cleaning the furnace bottom residue with the moving scraper, the operator moves the scraper towards the cleaning port and slides the limiting block at the lower end of the U-shaped groove; when the scraper needs to be reset, the operator moves the scraper away from the cleaning port and slides it at the upper end of the U-shaped groove, thereby realizing the reset operation, which helps to improve work efficiency.

[0015] Optionally, a support base is provided on the outside of the feed inlet of the furnace body, and a feed pipe is vertically provided on the support base. A hopper is provided inside the feed pipe, and several through holes are opened on the hopper to facilitate the falling of residue. A connection port is opened on the side of the feed pipe near the furnace body. The connection port is directly opposite the feed inlet of the furnace body and has the same shape and size. The hopper is located at the connection port of the furnace body and the feed inlet of the furnace body. Two guide rails are fixedly connected inside the furnace body to support the hopper. The hopper is slidably connected to the guide rails. The guide rails extend along the length of the furnace body. The two ends of the guide rails are fixedly connected to the two ends of the furnace body. A telescopic cylinder is also fixedly connected on the support base. The piston rod of the telescopic cylinder passes through the feed pipe and is fixedly connected to the hopper.

[0016] By adopting the above technical solution, when forging tungsten and molybdenum raw materials, the workers first add the tungsten and molybdenum into the feed pipe, allowing it to fall onto the loading hopper. Then, the telescopic cylinder is activated, and the piston rod of the telescopic cylinder extends forward, driving the loading hopper into the slide rail inside the furnace. The materials are then forged and heated by the spiral heating tube. After forging, the residue falls into the bottom of the furnace through the through hole without affecting the material of the forged tungsten and molybdenum, which helps to improve cleaning efficiency.

[0017] Optionally, a clamping block is fixedly connected to the side of the hopper near the telescopic cylinder, and a clamping groove is provided on the inner wall of the feed pipe. When the hopper is located inside the feed pipe, the clamping block is located in the clamping groove.

[0018] By adopting the above technical solution, the clamping block is located within the clamping groove. The cooperation between the clamping block and the clamping groove can limit the movement of the loading hopper, improving the stability of the structure.

[0019] Optionally, the heater is a spiral heating tube, which is sleeved on the outside of two guide rails. Several connecting rods are fixedly connected to the top of the spiral heating tube. One end of the connecting rod is fixedly connected to the top of the furnace body, and the other end is fixedly connected to the spiral heating tube.

[0020] By adopting the above technical solution and using a spiral heating tube, the heating path is extended, making the heating more uniform and improving the heating effect.

[0021] Optionally, a support platform is provided below the furnace body, and the furnace body is set on the support platform. Collection boxes for collecting residue are provided on both sides of the furnace body. The two collection boxes are located on the outside of the two cleaning ports of the furnace body, and the collection boxes extend along the length of the furnace body. The two collection boxes are fixedly connected to both sides of the support platform.

[0022] By adopting the above technical solution, the cleaned residue goes directly into the collection box, avoiding pollution of the working environment and making it easier for people to handle it uniformly.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The two oppositely positioned cleaning ports, combined with the cleaning components, make the removal of residue more efficient and convenient, greatly improving the processing efficiency of metal materials.

[0025] 2. The cleaning components at the bottom of the heating furnace are cleverly designed to cover the entire furnace bottom area, allowing for thorough cleaning of residues without any blind spots, thus ensuring the cleanliness of the furnace interior and its operational efficiency.

[0026] 3. The residue falling through the cleaning port is collected in a collection box, which saves the cost of subsequent manual cleaning and achieves an environmentally friendly and orderly working environment. Attached Figure Description

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] This application discloses a waste incinerator that is easy to clean.

[0034] Reference Figure 1 and Figure 2 The heating furnace includes a furnace body 1 and a heater 2, wherein the furnace body 1 has a feed inlet 11 and a discharge outlet 12 at both ends. In particular, the furnace body 1 has cleaning inlets 13 on both sides, which are located at the bottom of the furnace body 1 and are opposite each other. Each cleaning inlet 13 is equipped with a cleaning component 3, which can effectively remove the residue accumulated at the bottom of the furnace.

[0035] Reference Figure 1 and Figure 2 Each cleaning component 3 includes a scraper 31, which is installed inside the furnace body 1, movably connected to the furnace body, and positioned approximately vertically. These scrapers 31 are placed near the center of the furnace body and extend along the length of the furnace body 1. Two traction rods 32 are provided on the side of the scraper 31 near the cleaning port 13, and the traction rods 32 are horizontally fixed to both ends of the scraper 31. A pull rod 33 is provided on the outside of the cleaning port 13 of the furnace body, with each end of the pull rod 33 connected to the distal end of one of the two traction rods 32. When furnace body residue needs to be cleaned, the scraper moves from the center of the furnace body to both sides, thereby cleaning the residue inside the furnace body. The vertical positioning of the scraper ensures sufficient contact between the scraper and the bottom of the furnace body, improving cleaning efficiency.

[0036] Reference Figure 2 Each lever 33 is fixed with a glove 34, which is put over the outside of the lever 33 to increase the comfort of operation and provide better grip.

[0037] Reference Figure 2 When it is necessary to clean the residue at the bottom of the furnace, the staff pulls the handle 34 and the lever 33 to move the traction rod 32 and the scraper 31, thereby pushing the residue out of the furnace body through the cleaning port 13.

[0038] Reference Figure 1 and Figure 3 The inner wall of the furnace body 1 has two U-shaped grooves 14, which are connected and opposite to each other. The openings of the two U-shaped grooves 14 are horizontally aligned and form a closed annular groove. Each end of the scraper 31 has a limiting block 35, which is slidably connected to the U-shaped groove 14 of the furnace body 1. The limiting block 35 slides along the groove opening of the annular groove, thereby switching the position of the limiting block 35 and further realizing the switching between cleaning and resetting the scraper 31. When cleaning residue from the furnace body 1, the limiting block 35 slides at the lower end of the two U-shaped grooves 14; when resetting the scraper 31, the limiting block 35 slides at the upper end of the two U-shaped grooves 14. Initially, the scraper 31 is located at the lower end of the U-shaped groove 14. When cleaning residue, the operator pushes the scraper 31 towards the cleaning port 13. At this time, the limiting block 35 slides in the lower part of the U-shaped groove 14, enhancing the stability of the scraper 31 during movement. When cleaning is complete and the scraper 31 needs to be reset, the operator will first move the scraper 31 through the arc-shaped part of the U-shaped groove 14 to switch the position of the limiting block 35 so that it is located at the upper end of the U-shaped groove 14. Then, the scraper 31 is pushed in the opposite direction so that the limiting block 35 slides with the upper part of the U-shaped groove 14, thereby completing the reset process. By switching the position of the limiting block 35, the transition between the cleaning and reset operations of the scraper 31 is realized.

[0039] Reference Figure 1 and Figure 2 A support base 4 is provided on the outer side of the feed inlet 11 of the furnace body 1, and a vertical feed pipe 41 is fixed on the support base 4. A hopper 42 is installed inside the feed pipe 41. The bottom of the hopper 42 has multiple through holes 421 to allow residue to fall off during heating. Inside the furnace body 1, two guide rails 5 extending along their length are fixed, and the hopper 42 can slide on these guide rails 5. Both ends of the guide rails 5 are fixed to the inner wall of the furnace body 1. When the hopper 42 is pushed into the furnace body 1, it can be stably supported by the two guide rails 5, which are made of high-temperature resistant material.

[0040] Reference Figure 1 and Figure 2 The support base 4 is also equipped with a telescopic cylinder 43. The telescopic cylinder 43 is a multi-stage telescopic cylinder, and the piston rod of the telescopic cylinder 43 is made of high-temperature resistant material. The piston rod of the telescopic cylinder 43 penetrates the feed pipe 41 and is fixedly connected to the loading hopper 42. By operating the telescopic cylinder 43, when tungsten and molybdenum need to be fed into the furnace, the telescopic cylinder 43 extends, thereby driving the tungsten and molybdenum raw materials on the loading hopper 42 into the furnace body. After heating is completed, the piston rod of the telescopic cylinder 43 is extended outward again, so that the loading hopper 42 extends out of the discharge port 12, thereby facilitating the collection of tungsten and molybdenum. When resetting is required, the operator activates the telescopic cylinder 43 to retract the loading hopper 42 into the feed pipe 41, easily controlling the movement of the loading hopper 42 between the feed pipe 41 and the furnace body 1.

[0041] Reference Figure 2 and Figure 4 To enhance the stability of the hopper 42 during its movement in and out of the furnace, a clamping block 422 is fixed to the side of the hopper 42 near the telescopic cylinder 43. Correspondingly, a clamping groove 411 is provided on the inner wall of the feed pipe 41. When the hopper 42 is pushed into the feed pipe 41, the clamping block 422 will embed into the clamping groove 411, providing stable support for the hopper 42.

[0042] Reference Figure 1 and Figure 2Two cleaning ports 13, the feed port 11 of the furnace body 1 and the discharge port 12 are all hinged with a sealing door 15. The sealing door 15 of the feed port 11 is hinged to the top of the feed port. The sealing door 15 of the feed port 11 has a movable groove with the opening of the movable groove facing vertically downward, which is used to place the piston rod of the telescopic cylinder 43. When tungsten-molybdenum forging is required, all closed doors 15 are in the closed state. The movable groove on the closed door 15 of the feed inlet 11 can just accommodate the telescopic cylinder 43 that extends into the furnace body 1. When the telescopic cylinder 43 needs to be retracted, the closed door 15 of the feed inlet 11 flips upward to open, realizing the reset of the telescopic cylinder 43. The setting of the closed door 15 can reduce heat loss, thereby meeting the temperature requirements of forging. At this time, the telescopic cylinder 43 will drive the hopper 42 to open the closed door 15 and enter the furnace body 1. After the hopper 42 enters the furnace body 1, the closed door 15 closes. The piston rod part of the telescopic cylinder 43 is located at the movable groove of the closed door 15 to ensure the normal opening and closing of the closed door 15. When the hopper 42 needs to be reset, the telescopic cylinder 43 retracts, driving the hopper 42 to open the closed door 15 and leave the furnace body 1. In the non-forging state, when the operator opens the closed door 15, the heat will dissipate from the opening, thereby realizing the rapid cooling of the heating furnace.

[0043] Reference Figure 1 The heater 2 is designed as a spiral heating tube 21, which not only wraps around the outside of the two guide rails 5, but is also stably fixed to the top of the furnace body 1 by multiple connecting rods 22. This spiral design greatly extends the heating path, ensuring that the tungsten-molybdenum material can be heated evenly inside the furnace.

[0044] Reference Figure 1 A support platform 6 is provided below the furnace body 1, and the furnace body 1 is set on the support platform 6. Collection boxes 61 for collecting residue are provided on both sides of the furnace body 1. The two collection boxes 61 are located outside the two cleaning ports 13 of the furnace body 1, respectively, and extend along the length of the furnace body 1. The two collection boxes 61 are fixedly connected to both sides of the support platform 6. The cleaned residue directly enters the collection box 61, avoiding pollution of the working environment and facilitating unified treatment.

[0045] The implementation principle of a waste incinerator that is easy to clean, according to an embodiment of this application, is as follows: When tungsten-molybdenum raw materials need to be forged, the workers first add the raw materials into the feed pipe 41, allowing them to fall into the loading hopper 42. Then, the telescopic cylinder 43 is activated, which drives the loading hopper 42 along the guide rail 5 into the furnace body 1. Inside the furnace body 1, the raw materials are heated and forged by the heater 2. After forging is completed, the residue falls to the bottom of the furnace through the through hole 421 on the loading hopper 42.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
