Abstract
Description
Technical Field
[0001] This application relates to the field of boiler accessories, and more specifically to boiler-based anti-clogging feed structures. Background Technology
[0002] A boiler is an energy conversion device. The energy input to a boiler includes the chemical energy of fuel and electrical energy, while the output is steam, high-temperature water, or organic heat carriers with a certain amount of thermal energy. Currently, the common boiler operation method involves adding combustion media such as coal. However, coal is a non-renewable resource and contains various toxic and harmful substances. Its combustion produces large amounts of difficult-to-treat flue gas, which is not only harmful to human health but also pollutes the atmosphere, failing to meet current societal needs. To better protect the environment and reduce the use of non-renewable resources, biomass boilers have emerged. They effectively recycle waste materials such as grass, wood, and crop stalks as combustion media, reducing material costs and providing a new model for waste disposal, thus effectively meeting societal needs. However, biomass materials vary greatly in size, and traditional methods of feeding them into the boiler can easily lead to material accumulation and blockage of the feed inlet, necessitating improvements to the feeding structure.

[0036] Example 1
[0037] like Figure 1-2 As shown, the anti-clogging feeding structure based on the boiler is connected to the boiler feed inlet and includes a pipe section 100 and a crushing section 200 connected to the pipe section 100.
[0038] The pipeline section 100 consists of a feed hopper 101, a feed screening pipe 102 connected to the feed hopper 101, an interface pipe 103 connected to the feed screening pipe 102, a small material pipe 104 connected to the interface pipe 103, a large material pipe 105 connected to the interface pipe 103 and located above the small material pipe 104, and vibrators 106 respectively disposed on the lower side of the feed screening pipe 102, the small material pipe 104 and the large material pipe 105; each of the vibrators 106 is connected to a power source.
[0039] The lower sidewalls of the feeding screening pipe 102, the small material pipe 104, and the large material pipe 105 are all corrugated plates with an incline, and the grooves of the corrugated plates are parallel to the incline direction.
[0040] The corrugated plates in the feed screening pipe 102 and the large feed pipe 105 have an inclination angle of 30°; the small feed pipe 104 has an inclination angle of 60°.
[0041] The material enters the feeding screening pipe from the feed hopper. Since the feeding screening pipe will vibrate continuously with the vibrator, the material can be effectively stratified. At the interface pipe, small materials fall into the small material pipe and large materials enter the large material pipe. The vibration of the small material pipe and the large material pipe can ensure that the material can continue to move along them.
[0042] Small materials travel in the grooves between the corrugations, while large materials travel on the top surface of the corrugations. The rod-shaped materials in the large materials will also adjust their own direction when vibrating, and the axis of the rod-shaped materials will be parallel to the groove, so that the rod-shaped materials can enter the large material pipe at the interface pipe.
[0043] The crushing section 200 consists of a crushing hopper 210 connected to the large feed pipe 105, a crushing box 220 disposed below the crushing hopper 210, a collection port 230 disposed below the crushing box 220, and a boiler feed pipe 240 vertically disposed below the collection port 230.
[0044] The small feed pipe 104 passes through the side of the boiler feed pipe 240.
[0045] like Figure 4 , 5 As shown, the crushing box 220 is composed of a rectangular box body 221 with an opening in the middle of the upper side wall and an empty lower side wall, two pairs of bearing ports 228 symmetrically arranged on the left and right side walls of the box body 221, two crushing rollers 222 arranged laterally inside the box body 221 and respectively fixed on the corresponding bearing ports 228 with the central shaft, a collection port 227 formed by the downward tilting of the upper side walls on both sides of the opening of the upper side wall, and a drive device for driving the two crushing rollers 222 to run in opposite directions.
[0046] The outer wall of the crushing roller 222 is provided with several sets of crushing cones 223 in the transverse direction. A U-shaped groove 224 is provided between any two adjacent sets of crushing cones 223. A push block 225 is provided in each U-shaped groove 224. A guide post 226 is symmetrically provided on the left and right sides of the push block 225. The several sets of crushing cones 223 are evenly arranged around the outer wall of the crushing roller 222.
[0047] The inner sides of the left and right side walls of the housing 221 are respectively provided with two guide grooves 229 that cooperate with the guide posts 226 on the two crushing rollers 222; the guide posts 226 are inserted into the matching guide grooves 229.
[0048] The guide groove 229 is arranged around the bearing opening 228, and the guide groove 229 is a circle with a downward convex part at the bottom.
[0049] During use, large materials enter the crushing hopper through the large feed pipe, then enter the box body through the crushing hopper, and fall between the two crushing rollers under the guidance of the collection port. The two crushing rollers run towards each other, crushing the large materials by squeezing and crushing them with the crushing cone. Finally, the crushed large materials and small materials are combined at the boiler feed pipe and enter the boiler for combustion.
[0050] Large materials may get stuck between the two sets of crushing cones when being squeezed by the crushing cones, which can easily affect the normal use of the product. Therefore, a pusher block that can move with the guide groove is designed. When the pusher block moves to the left, top, and right, it remains at the bottom of the U-shaped groove, and its surface is flush with the surface of the crushing roller. When it moves to the bottom, the guide groove protrudes downward, so the guide column will move downward along the guide groove, thereby driving the pusher block to extend out of the U-shaped groove. When the pusher block extends, it will push out the material that is supporting it, thus effectively preventing the material from getting stuck between the two sets of crushing cones.
[0051] It should be noted that all features disclosed in this specification, or all steps in all methods or processes disclosed, may be combined in any way, except for mutually exclusive features and / or steps.
[0052] Furthermore, the specific embodiments described above are exemplary. Those skilled in the art can devise various solutions inspired by the disclosure of this utility model, and these solutions all fall within the scope of this utility model and its protection. Those skilled in the art should understand that this utility model specification and its drawings are illustrative and not intended to limit the scope of the claims. The scope of protection of this utility model is defined by the claims and their equivalents.
