Description

Technical Field

[0001] This utility model relates to the field of water heater technology, specifically an environmentally friendly biomass water heater with an automatic feeding structure. Background Technology

[0002] With changes in economic levels and living environments, people's heating methods have also changed, with more and more families without centralized heating choosing biomass pellet water heaters. As a new type of heating equipment, biomass pellet water heaters are easy to install and have a wide range of applications. New environmental regulations have restricted the use of traditional coal-fired stoves, while biomass pellet water heaters use biomass pellets as raw materials. These are combustible pellets produced from common rural materials such as straw and sawdust through extrusion processes. They have advantages such as low price, high calorific value, easy combustion, and good storage, fundamentally eliminating the drawbacks of traditional coal-fired stoves—dirt, mess, and poor sanitation—and completely eliminating the dangers of coal poisoning.

[0003] According to announcement number CN215523257U, an environmentally friendly biomass water heater with an automatic feeding structure is disclosed, including a furnace body. The furnace body has a furnace chamber inside, and a feeding channel is provided on the upper part of the left side wall of the furnace chamber. The furnace chamber is connected to the inner cavity of a screw feeder through the feeding channel. The discharge end of the feeding channel is provided with a cover plate. The cover plate includes a sealing plate and a connecting plate. The sealing plate matches the discharge end of the feeding channel. The upper end of the connecting plate is hinged to the upper inner wall of the furnace chamber. A return spring is hinged inside the groove. The other end of the return spring is hinged to the connecting plate.

[0004] This device features a cover plate at the discharge end of the feeding channel. When feeding stops, the cover plate returns to its original position under its own weight and the tension of a return spring. The sealing plate on the cover plate covers the discharge end of the feeding channel, sealing it and preventing backfire, thus improving efficiency. Furthermore, the particle size and uniformity of biomass fuel before combustion significantly impact combustion efficiency. Excessively large or unevenly sized fuel particles lead to incomplete combustion, producing more smoke and unburned residue, reducing energy efficiency, and increasing environmental pollution.

Simultaneously, the heat-insulating plate on the rotating shaft effectively prevents reverse heat conduction within the furnace cavity, reducing heat loss. While ensuring smooth feeding, this improves the equipment's thermal efficiency, achieving energy conservation and consumption reduction. Attached Figure Description

[0027] Please see Figure 1-3 This utility model provides a technical solution: an environmentally friendly biomass water heater with an automatic feeding structure, including a furnace body 1, a crushing mechanism 2 on the left side of the furnace body 1, and a discharge mechanism 3 on the front of the crushing mechanism 2.

[0028] The crushing mechanism 2 includes a fixed frame 21, which is fixedly connected to the left side of the furnace body 1 near the top. A hopper 22 is fixedly connected to the inner wall of the fixed frame 21. A discharge cylinder 23 is fixedly connected to the bottom of the hopper 22.

A heat dissipation hole 26 is opened on the front of the protective box 25. A first crushing roller 27 is rotatably connected to the left side of the back of the inner wall of the hopper 22. A first gear 28 is fixedly connected to the surface of the first crushing roller 27 near the front end. A second crushing roller 29 is rotatably connected to the back of the inner wall of the hopper 22 near the right side. A second gear 211 is fixedly connected to the surface of the second crushing roller 29 near the front end. A first L-plate 212 is fixedly connected to the front of the hopper 22 near the left side. A first servo motor 213 is fixedly connected to the front of the first L-plate 212.

[0029] A groove matching the discharge cylinder 23 is provided on the right side of the furnace body 1 near the bottom, and the surface of the discharge cylinder 23 is penetrated and fixedly connected to the groove, with the discharge cylinder 23 extending into the furnace cavity inside the furnace body 1.

[0030] The top of the inclined plate 24 has a groove to facilitate feeding. The left and right sides of the front of the hopper 22 have holes that match the first crushing roller 27 and the second crushing roller 29. The surfaces of the first crushing roller 27 and the second crushing roller 29 are respectively penetrated and rotatably connected in the holes.

[0031] The first gear 28 meshes with the second gear 211, and the output end of the first servo motor 213 is fixedly connected to the front end of the first crushing roller 27.

[0032] The first L-plate 212, the first servo motor 213, the first gear 28, and the second gear 211 are all located inside the protective box 25 for protection.

[0033] Example 2

[0034] Please see Figure 4 Furthermore, based on Example 1, the discharge mechanism 3 was obtained.

[0035] The discharge mechanism 3 includes a second L-plate 31, which is fixedly connected to the front of the discharge cylinder 23. A second servo motor 32 is fixedly connected to the front of the second L-plate 31. A fan-shaped roller 33 is fixedly connected to the inner wall surface of the discharge cylinder 23 near the bottom. A rotating shaft 34 is rotatably connected to the front and rear sides of the inner wall of the discharge cylinder 23 near the top. A heat-insulating plate 35 is fixedly connected to the surface of the rotating shaft 34.

[0036] The discharge cylinder 23 has a hole on its front that matches the fan-shaped roller 33, and the surface of the fan-shaped roller 33 is penetrated and rotatably connected to the hole. The output end of the second servo motor 32 is fixedly connected to the front end of the fan-shaped roller 33.

[0037] In actual operation, when this device is in use, biomass raw materials are fed from the top of the hopper 22. The groove at the top of the inclined plate 24 guides the raw materials to the first crushing roller 27 and the second crushing roller 29. The first servo motor 213 is started, and its output end drives the first crushing roller 27 to rotate. Through the meshing transmission of the first gear 28 and the second gear 211, the second crushing roller 29 rotates in the opposite direction. The first crushing roller 27 and the second crushing roller 29 work together to crush the biomass raw materials into small pieces.

The crushed biomass raw materials fall into the discharge cylinder 23, and the second servo motor 213 is started. The servo motor 32 drives the fan-shaped roller 33 to rotate. The rotation of the fan-shaped roller 33 pushes the raw material quantitatively into the furnace cavity inside the furnace body 1. By controlling the speed of the second servo motor 32, the rotation speed of the fan-shaped roller 33 can be precisely adjusted, thereby controlling the feeding amount and feeding speed. The heat-insulating plate 35 can rotate inside the discharge cylinder 23 via the rotating shaft 34. When feeding is not required, the heat-insulating plate 35 can be rotated to block the heat in the furnace cavity from being conducted to the discharge cylinder 23, further improving thermal efficiency. The protection box 25 protects the first L plate 212, the first servo motor 213, the first gear 28, and the second gear 211 to prevent dust and debris from entering and to ensure the stable operation of the transmission system.
