Technical Field

[0001] This utility model is an integrated equipment for crushing and drying biomass fuel, belonging to the field of biomass fuel processing technology. Background Technology

[0002] The production of biomass fuels (such as straw, sawdust, and agricultural and forestry waste) requires two key steps: crushing and drying. In existing technologies, crushing and drying are usually separate processes: crushing equipment (such as hammer crushers) pulverizes the raw materials, which are then dehydrated by separate drying equipment (such as hot air drying chambers).

[0003] However, separating crushing and drying operations leads to high energy consumption, low efficiency, and residual moisture after crushing, which affects the drying effect. There is an urgent need for an integrated crushing and drying equipment for biomass fuel to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide an integrated biomass fuel crushing and drying device to solve the problems mentioned in the background. This invention combines crushing and drying structures, enabling the crushing and drying of biomass fuel. During this process, residual hot air can be collected and circulated through a circulating air duct, which can then be used to preheat the added biomass fuel and improve the drying quality of the biomass fuel.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A biomass fuel crushing and drying integrated equipment includes an integrated processing box and a circulating air duct. The integrated processing box has a feed inlet on the front side of its upper end, a support base at the lower end of the integrated processing box, a fan frame bolted to the upper end of the integrated processing box, and a fan and a disc heating tube installed inside the fan frame. The disc heating tube is located at the air outlet of the fan. A servo motor is installed on the right side of the upper end of the support base. Two rotating shafts are installed inside the integrated processing box through multiple bearing seats, and a first crushing blade group and a second crushing blade group are respectively installed outside the two rotating shafts. A first gear and a second gear are respectively installed at the rear ends of the first crushing blade group and the second crushing blade group. Inclined plates are integrally provided on the lower sides of both the left and right ends of the integrated processing box. The upper ends of the two inclined plates are connected to the circulating air duct. Auxiliary air outlets are symmetrically opened on the upper ends of both the left and right sides of the integrated processing box.

[0006] Furthermore, a discharge hopper is installed at the lower end of the support base, the upper end of the discharge hopper is connected to the interior of the integrated processing box, and a movable baffle is installed at the left end of the discharge hopper via a hinge.

[0007] Furthermore, the first gear and the second gear mesh and drive each other, a driven wheel is installed at the front end of the left rotating shaft, and a driving wheel is provided at the end of the servo motor shaft.

[0008] Furthermore, a transmission belt is fitted between the driven wheel and the driving wheel.

[0009] Furthermore, inclined grooves are provided on the outer sides of both circulating air ducts, and slide rails are provided at the front and rear ends of the two inclined grooves. A filter screen is slidably inserted between each pair of opposite slide rails.

[0010] Furthermore, the upper ends of the two circulating air ducts are respectively welded to two auxiliary air outlets.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an integrated biomass fuel crushing and drying device. Because it incorporates an integrated processing box, a fan, a disc-shaped heating tube, a servo motor, a first crushing blade assembly, a first gear, a second gear, a second crushing blade assembly, an inclined plate, and a circulating air duct, our design improvements and practical use have shown that this device has a reasonable structure and good practicality. The combined crushing and drying structure enables the crushing and drying of biomass fuel. During this process, the remaining hot air can be collected and circulated using the circulating air duct, which can then be used for auxiliary preheating of the added biomass fuel, improving the drying quality of the biomass fuel.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: an integrated biomass fuel crushing and drying equipment, including an integrated processing box 1 and a circulating air duct 13. The integrated processing box 1 has a feed inlet 4 on its upper front side, and a support base 5 at its lower end. A fan frame is bolted to the upper end of the integrated processing box 1, and a fan 2 and a disc-shaped heating tube 3 are installed inside the fan frame. The disc-shaped heating tube 3 is located at the air outlet of the fan 2. A servo motor 6 is installed on the upper right side of the support base 5. Two rotating shafts are installed inside the integrated processing box 1 through multiple bearing seats, and the two rotating shafts are externally... The integrated processing box 1 is equipped with a first crushing blade group 8 and a second crushing blade group 11. The rear ends of the first crushing blade group 8 and the second crushing blade group 11 are respectively equipped with a first gear 9 and a second gear 10. The lower sides of the left and right ends of the integrated processing box 1 are both integrally provided with inclined plates 12. The upper ends of the two inclined plates 12 are connected to circulating air ducts 13. The upper ends of the left and right sides of the integrated processing box 1 are symmetrically provided with auxiliary air vents 15. This design solves the problem that in the existing technology, the crushing and drying of biomass fuel are separated, resulting in high energy consumption, low efficiency, and easy residue of moisture after crushing, which affects the drying effect.

[0019] As the first embodiment of this utility model: a discharge hopper 16 is installed at the lower end of the support base 5, the upper end of the discharge hopper 16 is connected to the interior of the integrated processing box 1, and a movable baffle 17 is installed at the left end of the discharge hopper 16 through a hinge. The added discharge hopper 16 can cooperate with the closed movable baffle 17 to collect the crushed biomass fuel.

[0020] The first gear 9 and the second gear 10 mesh and drive each other. A driven wheel 7 is installed at the front end of the left rotating shaft, and a driving wheel is provided at the shaft end of the servo motor 6. A transmission belt is sleeved between the driven wheel 7 and the driving wheel. Through the meshing and transmission between the added first gear 9 and the second gear 10, the first crushing blade group 8 and the second crushing blade group 11 can be adjusted to rotate in opposite directions respectively. A transmission belt is sleeved between the driven wheel 7 and the driving wheel, so that when the servo motor 6 is working, it can drive the left rotating shaft to rotate through the driven wheel 7.

[0021] Both circulating air ducts 13 have inclined grooves on their outer sides, and slide rails are installed at both the front and rear ends of the two inclined grooves. A filter screen 14 is slidably inserted between each pair of opposing slide rails. The added filter screen 14 can intercept and filter impurities in the flowing gas passing through the two circulating air ducts 13. The upper ends of the two circulating air ducts 13 are respectively welded to two auxiliary air outlets 15. By adding two circulating air ducts 13 and welding their upper ends to two auxiliary air outlets 15, when flowing gas is introduced into the two circulating air ducts 13 from bottom to top, it can be blown out through the two auxiliary air outlets 15.

[0022] As a second embodiment of this utility model: The servo motor 6 is started, driving the drive wheel to rotate clockwise. The drive wheel, via a transmission belt, drives the driven wheel 7 to rotate clockwise. The driven wheel 7 then drives the left rotating shaft to rotate clockwise, thereby causing the first crushing blade assembly 8 and the first gear 9 to rotate clockwise. The second gear 10 meshes with the first gear 9 and rotates counterclockwise, which in turn drives the second crushing blade assembly 11 to rotate counterclockwise. Then, biomass fuel is added into the integrated processing box 1 through the feed inlet 4. The first crushing blade assembly 8 and the first gear 9 rotate counterclockwise. The second pulverizing blade assembly 11 will pulverize the biomass fuel. The blower 2 and the disc heating tube 3 will be started. The blower 2 will drive the external air flow, and the added biomass fuel will be heated and dried through heat exchange with the disc heating tube 3. The hot air will enter the lower part of the integrated processing box 1 to dry the pulverized biomass fuel. During this process, the hot air below will flow back to the two auxiliary air outlets 15 through the two circulating air pipes 13, so that the two auxiliary air outlets 15 will blow out hot air to assist in the preheating treatment of the biomass fuel at the feed inlet 4.
