Description

Technical Field

[0001] This utility model relates to the field of waste treatment equipment technology, and in particular to a high-humidity waste gasification feeding device and gasifier. Background Technology

[0002] Urban solid waste processing conditions are complex, and pretreatment processes are generally simple. Waste has high moisture content and poor homogeneity. The guide rails of the waste feeding device are in direct contact with the waste, significantly reducing the device's reliability. Furthermore, entanglement of some waste can block feeding, leading to equipment malfunction. Some conditions require long-stroke feeding, such as those exceeding 2 meters. In such cases, a single hydraulic pusher is unsuitable. Therefore, a structural device capable of long-stroke feeding is needed to achieve this function. This application addresses these issues. Utility Model Content

[0003] The purpose of this invention is to provide a high-humidity waste gasification feeding device and a gasifier, which solves the problems of poor homogeneity during waste feeding, low reliability of the feeding device caused by the direct contact between the travel guide rail of the waste feeding device and the waste, and difficulty in achieving long-stroke feeding and propulsion.

[0004] To address the aforementioned problems, this utility model provides a high-humidity waste gasification feeding device, comprising a feeding drive module, a support and guide module, and a feeding module. The feeding module includes a feeding hopper, an outer frame connected to the feeding hopper, and fixed shearing blades disposed within the outer frame. The outer frame is provided with a docking end for connection to the gasifier. The feeding drive module includes a movable shearing blade assembly, a mounting reinforcement base plate connected to the movable shearing blade assembly, a tie rod connected to the mounting reinforcement base plate, a frame structure connected to the mounting reinforcement base plate, a rack connected to the frame structure, a drive gear pair connected to the rack transmission, and a drive reduction motor for providing power to the drive gear pair. The support and guide module includes a column tube for guiding the frame structure, several directional wheel sets for limiting and guiding the column tube, and a hydraulic push rod assembly connected to the tie rod. When waste is pushed out, the hydraulic push rod assembly and / or the drive reduction motor drive the movable shearing blade assembly to move towards the fixed shearing blades.

[0005] According to one embodiment of the present invention, the frame structure includes a frame structure and a lower frame. Both the frame structure and the lower frame are connected to racks, one set of racks being connected to a drive gear pair and the other set of racks being connected to a follower gear pair.

[0006] Preferably, a hydraulic push rod assembly is used as the power source, in which case the drive gear pair and the follower gear pair serve as the main motion loads.

[0007] Optionally, a drive geared motor is used as the power source, the drive gear pair is used as the main motion load, and the follower gear pair is used as the matching load.

[0008] Alternatively, the drive geared motor and the hydraulic push rod assembly can be used together as the power source.

[0009] According to one embodiment of the present invention, the column tube is provided in several groups, and each group of column tubes is provided with three groups of directional wheels. The three groups of directional wheels are evenly distributed on the 270° circumference of the column tube, which plays a supporting and guiding role.

[0010] According to one embodiment of the present invention, an expansion joint is provided at the docking end of the outer frame for connecting with the gasifier, in order to solve the expansion caused by the temperature of the gasifier, and to enable the maintenance of related components through disassembly and assembly.

[0011] According to one embodiment of the present invention, the outer frame is provided with a blocking member and a drainage hole. The blocking member is used to prevent the squeezed water or garbage from being carried into the rear space during the return motion, causing garbage accumulation. The front end of the blocking member is provided with a drainage hole for drainage, so as to prevent squeezed water from entering the gasifier.

[0012] According to one embodiment of the present invention, the feeding drive module and the support guide module are installed at an angle, preferably at an angle of 1° to 3°, so that the sewage that seeps out due to the squeezing during the garbage feeding process is discharged to the rear and discharged through the drainage hole in front of the outer frame, thereby reducing the moisture content of the garbage entering the furnace.

[0013] According to one embodiment of the present invention, the feeding drive module further includes a backrest wheel, which is used to adjust the meshing clearance between the drive gear pair and the rack.

[0014] According to one embodiment of the present invention, the support and guide module further includes a guide frame, the push rod of the hydraulic push rod assembly is disposed in the guide frame, and a lubrication layer is provided between the push rod and the guide frame, preferably lubricating oil.

[0015] The gasifier includes the aforementioned high-humidity waste gasification feeding device.

[0016] According to one embodiment of the present invention, the high humidity waste gasification feeding device is provided in two sets, and the feeding drive module can work asynchronously or in reverse to balance the pressure fluctuations inside the furnace during the feeding process and solve the problem of the impact on the gas pressure stability inside the gasifier during the waste gasification feeding process.

[0017] The beneficial effect of this utility model is that the reinforced mounting plate that comes into contact with the garbage in this solution is not the main moving load-bearing component. Its linear motion is mainly achieved by the engagement of the hydraulic push rod assembly and / or the drive gear pair with the rack, and the corresponding positioning is achieved through the cooperation of the column tube, thereby achieving precise feeding control. This greatly reduces the cooperation requirements between the reinforced mounting plate and the outer frame and improves the stability of the entire system.

[0018] This solution provides two power output structures. The power design of the hydraulic push rod assembly and the drive geared motor can meet the requirements of long-stroke feeding control and harsh operating conditions, which greatly reduces the technical requirements of the hydraulic push rod assembly.

[0019] By setting up moving shear blade groups and fixed shear blades, functions such as crushing and extrusion are provided, which enhances the homogeneity of the waste entering the furnace and is conducive to further gasification and combustion. Attached Figure Description

The embodiments in the following description are merely examples, and those skilled in the art will conceive of other obvious modifications. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other solutions that do not depart from the spirit and scope of the present invention.

[0034] High-humidity waste gasification feeding device, such as Figure 1 The present invention mainly includes a feeding module 3, a support and guide module 2, and a feeding drive module 1. The main functions of the feeding module 3 are to provide a feeding hopper, a feeding channel for the feeding device, docking and connection with the gasifier, expansion, disassembly and assembly, etc.; the support and guide module 2 is the main running frame support and guide support for the feeding drive module 1, and provides corresponding fixing devices; the feeding drive module 1 is the main moving part, which completes the feeding, shearing and crushing, extrusion and drainage of materials through linear motion.

[0035] The feeding drive module 1 mainly includes a movable shearing blade assembly 100, a mounting reinforcement base plate 101 connected to the movable shearing blade assembly 100, a tie rod 102 connected to the mounting reinforcement base plate 101, a frame structure connected to the mounting reinforcement base plate 101, a rack 406 connected to the frame structure, a drive gear pair 107 connected to the rack 406, and a drive geared motor 104 for providing power to the drive gear pair 107.

[0036] The reinforcing base plate 101 is the main load-bearing component. It is made of thick steel plate and can be installed on the movable shearing blade assembly 100 by fastener connection, which can be disassembled and assembled. The movable shearing blade assembly 100 is made of wear-resistant and temperature-resistant material, preferably hard alloy material such as 42CrMo.

[0037] The connection between the reinforcing base plate 101 and the reinforcing mounting plate 103 is achieved through a fastening connection, allowing for assembly and disassembly. The reinforcing mounting plate 103 is preferably made of carbon steel and has a closed structure on all sides. The front end is closed by the moving shear blade assembly 100, with only the rear side being open, and the other sides forming a closed channel. The upper part mainly contacts the waste from the hopper, and through the squeezing and pushing of linear motion, a self-cleaning process can be formed within the outer frame 301.

[0038] The mounting base plate 101 and the reinforcing mounting plate 113 are connected by welding or fastening. The tie rod 102 is connected to one end of the reinforcing mounting plate 113 by threaded connection. The other end of the reinforcing mounting plate 113 is connected to the connecting lug 110 by welding.

[0039] The reinforced mounting plate 103 is connected to the upper frame 106 and the lower frame 108 by fasteners.

[0040] A buffer pad 111 is provided at the top of the motor mounting base plate 105. The buffer pad 111 is preferably made of elastic material such as rubber. It achieves fastening and vibration absorption by fastening and pressing. A drive geared motor 104 is fastened on the motor mounting base plate 105. The number of drive geared motors 104 can be adjusted according to the actual working conditions, preferably 2. The end of the drive geared motor 104 is fastened with a drive gear pair 107 through splines, anti-reverse nuts, and retaining rings, which is the main transmission component.

[0041] A backrest wheel 404 is also installed on the motor mounting base plate 105. The meshing clearance between the drive gear pair 107 and the rack 406 can be achieved by adjusting the backrest wheel 404.

[0042] like Figure 6 The motor mounting base plate 105 is also equipped with a safety hook 405. The main function of the safety hook 405 is to prevent the gear from falling off due to excessive meshing clearance, and to achieve a safety limit. It is preferred to install two hooks, one on the top and one on the bottom.

[0043] The support and guide module 2 mainly includes a column tube 201 for guiding the frame structure, several directional wheel sets for limiting and guiding the column tube 201, and a hydraulic push rod assembly 205 connected to the tie rod 102.

[0044] like Figure 6The upper frame 106 and the lower frame 108 are each equipped with a complete set of directional wheel group 1 401, directional wheel group 2 402 and directional wheel group 3 403, which are staggered. The three roller groups are arranged around the three sides of the column tube 201, which can realize positioning and guidance on the column tube 201. Each column tube 201 is the running track of the upper frame 106 and the lower frame 108.

[0045] The fixed shafts of the first directional wheel assembly 401, the second directional wheel assembly 402, and the third directional wheel assembly 403 can be optionally set to an eccentric setting to achieve adjustment of the working clearance with the column tube 201.

[0046] The upper frame 106 runs on the upper column tube 201, and the lower frame 108 runs on the lower column tube 201; the drive geared motor 104 can be selected as the power source. When there are multiple drive geared motors 104, a three-phase asynchronous motor can be selected to configure the reduction mechanism.

[0047] The column tube 201, the reinforcing frame 202, the positioning sleeve 210, the reinforcing member 407, and the safety hook 405 can be combined to form a standard section 200, forming a standard component. There can be multiple standard sections 200, and two are used as an example here. They are fixed by setting a fixed foundation at the end and connecting to the relevant embedded parts or structural parts. At the same time, corresponding fasteners can be set in the positions that the reinforcing mounting plate 103 cannot reach to achieve fixation.

[0048] Its main operating channel is the column tube 201, which is mainly composed of thick-walled steel pipes. Corresponding grooves and positioning sleeves 210 are set at the beginning and end, and a fastening connection is formed by fasteners in the fastener connection holes 408. The standard section 200 is provided with a reinforcing frame 202 at the top, middle and bottom, and can be further provided with diagonal tie rods to form a truss structure with strong structural performance. The middle section of the reinforcing frame 202 is provided with a mounting base 203 for mounting the hydraulic push rod assembly 205, and a hinge is realized at this point.

[0049] The second standard section 200 is internally connected to a guide frame 204 via fasteners. The guide frame 204 has a lubrication port 209 for lubrication and a lubrication channel inside. Pressure regulation and power source can be achieved by controlling the flow of hydraulic oil in and out of the inlet / outlet ports 208. The push rod 206 has a connecting lug 207 at its end, which is connected to a connecting lug 110 via a pin. During its reciprocating linear motion, the push rod 206 drives the pull rod 102 through the guide frame 204, thereby driving the movement of the entire upper frame 106 and lower frame 108 on the column tube 201, the meshing motion of the drive gear pair 107 and rack 406, and the movement of the backrest wheel 404 on the back of the rack 406, thus driving the linear reciprocating motion of the entire feeding drive module 1. The movable shearing blade assembly 100 on the feeding drive module 1, in cooperation with the fixed shearing blade 305, achieves shearing, crushing, and extrusion of materials.

[0050] The feeding module 3 mainly includes a feeding hopper 300, an outer frame 301 connected to the feeding hopper 300, and a fixed shearing blade 305 set in the outer frame 301. The outer frame 301 is provided with a docking end for connecting to the gasifier.

[0051] The feeding module 3 is connected and fixed to the structural components or foundation through the support base 304. The support base 304 is connected to the outer frame 301 by welding or fastening. One end of the outer frame 301 is provided with a flange connection pair 302 to control the sealing gap as much as possible and achieve relative sealing.

[0052] like Figure 5 The outer frame 301 is internally equipped with a blocking component 310 to prevent squeezed water or debris from being carried into the rear space during the return motion, causing debris accumulation. The front end of the blocking component 310 ( Figure 5 A drain hole is provided on the left side of the middle blocking member 310 to drain water and prevent squeezed water from entering the gasifier.

[0053] The upper end of the outer frame 301 is provided with a feed hopper 300 for feeding materials. The bottom of the feed hopper 300 is provided with a fixed shearing blade 305, which is connected by fastening to realize the relevant shearing and crushing functions. Several maintenance manholes 303 are also provided on the outer frame 301 for maintenance.

[0054] The other end of the outer frame 301 is provided with a discharge port connecting plate 308 and an expansion joint 306 to solve the expansion from the temperature of the gasifier, and to enable the maintenance of related components through disassembly and assembly. The outer frame 301 extends into the gasifier interface 307 to achieve related connections. The gasifier interface 307 is fastened or welded to the gasifier cavity through a connecting flange 309.

[0055] The feeding module 3, the support and guide module 2, and the feeding drive module 1 are preferably used in pairs. This allows the feeding drive module 1 to operate asynchronously or in reverse, thus balancing pressure fluctuations within the furnace during the feeding process. The feeding drive module 1 is equipped with one or more limit switches 211, which, in conjunction with the travel switch control element 311, control the working stroke of the feeding drive module 1.

[0056] Preferably, the hydraulic push rod assembly 205 is used as the power source, in which case the drive gear pair 107 and the follower gear pair 109 serve as the main motion loads. Alternatively, the drive geared motor 104 can be used as the power source, with the drive gear pair 107 serving as the main motion load and the follower gear pair 109 serving as the supporting load.

[0057] Optionally, the hydraulic push rod assembly 205 and the drive geared motor 104 can be used together as the power source.

[0058] The preferred feeding drive module 1 and the support guide module 2 are installed at an angle of 1° to 3°, so that the sewage that seeps out due to the squeezing during the garbage feeding process is discharged to the rear and discharged through the drainage hole in front of the outer frame 301, thereby reducing the moisture content of the garbage entering the furnace.

[0059] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments.
