Description

Technical Field

[0001] The utility model relates to the technical field of biomass particle fuel processing, in particular to a highly efficient biomass particle fuel solidification and molding device. Background Art

[0002] Biomass pellet fuel is actually the direct combustion of biomass energy, which is the processing and utilization of biomass. Direct combustion methods can be divided into four types: stove combustion, boiler combustion, garbage combustion and solid fuel combustion. Among them, solid fuel combustion is a newly promoted technology. It solidifies the biomass into a shape and then uses traditional coal-fired equipment to burn it. Its advantages are that it makes full use of biomass energy to replace coal, reduces CO2 and SO2 emissions, is beneficial to environmental protection and controls greenhouse gas emissions, slows down climate change, and reduces the occurrence of natural disasters;

[0003] Biomass fuel is a new environmentally friendly new energy source in the form of columns produced by processing straw, rice straw, rice husk, peanut shell, corn cob, oil tea shell, cottonseed shell and other "three wastes". Biomass shaped fuel uses agricultural and forestry waste as raw materials, and is made into various shapes such as blocks and granules through processes such as crushing, mixing, extrusion and drying. It is a new type of clean fuel that can be directly burned.

[0004] Biomass fuel molding equipment is used in the production and processing of biomass pellet fuel. The agricultural and forestry discards are pre-treated to a certain moisture content, processed to a length or size suitable for entering the molding machine, and then automatically or manually fed into the fuel molding equipment. There is a moving mold on the rotating main shaft in the molding equipment, which is generally a roller type. The material is gradually squeezed and heated between the fixed / moving molds of the equipment, and is extruded into a cylindrical or square column shape in the mold hole, and then cut into blocks or particles of a certain length. After cooling, the finished product can be packaged.

[0005] Conventional biomass fuel molding equipment is generally a roller type, but this structure is prone to material residue and has a single discharge port, which affects the processing efficiency to a certain extent.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and an efficient biomass pellet fuel curing and molding device is proposed. Utility Model Content

[0007] The purpose of the utility model is to provide an efficient biomass pellet fuel solidification molding device to solve the problems raised in the above background technology.

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an efficient biomass pellet fuel solidification molding device, comprising a molding component and a device seat component, a device seat component is arranged directly below the molding component, and auxiliary frame components are vertically installed on the left and right sides of the device seat component, and a driving component is mounted on the top of the auxiliary frame component, the molding component comprises a molding mold, an injection valve, a discharge hole, a buffer pile and a supporting slider, an injection valve is arranged in the middle of the back facade of the molding mold, and the bottom of the molding mold is equidistantly arrayed with discharge holes, and buffer piles are installed at the four diagonals of the bottom of the molding mold, and the left and right sides of the molding mold are connected to support sliders.

[0009] Furthermore, the device seat assembly includes a material receiving box, a material discharging door and a base. The material discharging door is provided on the front and side elevations of the material receiving box, and the bottom of the material receiving box is connected to the base.

[0010] Furthermore, the device seat assembly also includes a stabilizing platform and shock-absorbing struts. The stabilizing platform is installed on the left and right sides of the base. Shock-absorbing struts are vertically installed at the four diagonals of the material receiving box, and the material receiving box is arranged directly below the forming mold.

[0011] Furthermore, the stabilizing platform is symmetrically arranged on the receiving box and is welded to the base, and the shock-absorbing strut is arranged directly below the buffer pile.

[0012] Furthermore, the auxiliary frame assembly includes a support frame, a stepper motor and a lead screw. The stepper motor is vertically installed on the top of the support frame, and the lead screw is installed on the bottom power output end of the stepper motor through a coupling.

[0013] Furthermore, the support frame is vertically fixed to the top of the stabilizing platform, and the support slider is threadedly connected to the lead screw.

[0014] Furthermore, the driving assembly includes a main beam frame, a fixed frame, a hydraulic push rod and a pressure plate. The middle end of the main beam frame is symmetrically connected to the fixed frame, and the bottom of the fixed frame is vertically installed with a hydraulic push rod, and the bottom of the hydraulic push rod is installed with a pressure plate.

[0015] Furthermore, the surface dimension structure of the pressing plate matches the internal dimension structure of the forming mold, and the main beam frame and the fixing frame are welded to each other in a "cross" structure.

[0016] The utility model provides an efficient biomass pellet fuel curing and molding device, which has the following

[0017] Beneficial effects:

[0018] 1. The utility model has a plurality of discharge holes arrayed at the bottom of the forming mold. When the material is injected into the forming mold, the hydraulic push rod is vertically extended and retracted to drive the pressure plate connected to the power output end at the bottom thereof to push the material inside the forming mold as far as possible toward the bottom thereof. Under the action of the huge pressure, the material is compressed and gradually squeezed out from the plurality of discharge holes. By using the above structure, the efficiency of the operation of the entire device can be guaranteed as much as possible. At the same time, the forming component is used in conjunction with the structure of the driving component. While avoiding the material from remaining inside the forming mold as much as possible, the uniformity of the pressure forming force can be effectively ensured.

[0019] 2. The utility model provides auxiliary frame assemblies on the left and right sides of the forming assembly, and utilizes the support sliders on the left and right sides of the forming mold to be threadedly connected to the lead screw. When the stepper motor is in operation, it will drive the lead screw connected to the bottom power output end thereof to rotate axially in the vertical direction. As the lead screw rotates, the forming mold will move up and down along the surface of the lead screw through the support slider. By utilizing the operation of this structure, when the driving assembly provides a downward pressure in the vertical direction to the forming mold, the structure of the auxiliary frame assembly is used to drive the entire forming assembly to be vertically lifted, thereby cooperating with the top-down force of the driving assembly to provide a bottom-up thrust. By utilizing the two-way pressure, the material inside the forming mold can be acted on to the greatest extent, thereby ensuring the efficiency of extrusion molding, and outputting it from the inside of the discharge hole, thereby ensuring the efficiency and quality of processing.

[0020] 3. The utility model, through the use of the device seat assembly, installs the receiving box with the discharge door just below the molding die, so that during the processing, the extruded molding material will directly fall into the interior of the receiving box, and due to the structural setting between the molding assembly and the device seat assembly, the problem of splashing and spilling of materials during output can be avoided as much as possible. When the processed molding material needs to be recovered, it is only necessary to open the discharge door on the side of the receiving box to quickly take out the material. In addition, the shock-absorbing struts vertically installed at the four corners of the discharge door can provide a certain degree of structural support for the molding assembly on the one hand, and can prevent the overall structure of the molding assembly from falling and causing major structural damage when the auxiliary frame assembly fails on the other hand, thereby playing a role in structural protection.

[0026] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0027] like Figures 1 to 4 As shown, an efficient biomass pellet fuel curing molding device includes a molding component 1 and a device seat component 2. The device seat component 2 is arranged directly below the molding component 1, and auxiliary frame components 3 are vertically installed on the left and right sides of the device seat component 2, and a driving component 4 is arranged on the top of the auxiliary frame component 3. The molding component 1 includes a molding mold 101, an injection valve 102, a discharge hole 103, a buffer pile 104 and a supporting slider 105. The injection valve 102 is arranged in the middle of the back side elevation of the molding mold 101, and the discharge holes are arranged in an equidistant array at the bottom of the molding mold 101. 103, and buffer piles 104 are installed at the four diagonal positions at the bottom of the molding die 101, and support sliders 105 are connected to the left and right sides of the molding die 101. When the material is injected into the molding die 101, the hydraulic push rod 403 is vertically extended and retracted, driving the pressure plate 404 connected to the power output end at its bottom. When pushing the molding die 101 from top to bottom, the material inside the molding die 101 will be pushed toward its bottom as much as possible. Under the action of huge pressure, the material will be compressed and gradually squeezed out from several discharge holes 103.

[0028] like Figures 1 to 4As shown, the device seat assembly 2 includes a material receiving box 201, a material discharge door 202 and a base 203. The material receiving box 201 is provided with a material discharge door 202 on the front and side elevations, and the bottom of the material receiving box 201 is connected to the base 203. The device seat assembly 2 also includes a stabilizing platform 204 and a shock-absorbing pillar 205. The stabilizing platforms 204 are installed on the left and right sides of the base 203. The shock-absorbing pillars 205 are vertically installed at the four diagonal parts of the material receiving box 201. The material receiving box 201 is arranged directly below the molding die 101. The stabilizing platform 204 is symmetrically arranged on the material receiving box 201 and connected to the base 203. They are welded together, and the shock-absorbing pillar 205 is arranged directly below the buffer pile 104. By installing the receiving box 201 with the discharge door 202 directly below the molding die 101, during the processing, the extruded molding material will directly fall into the interior of the receiving box 201, and due to the structural setting between the molding component 1 and the device seat component 2, the problem of splashing during material output can be avoided as much as possible. When the processed molding material needs to be recovered, it is only necessary to open the discharge door 202 on the side of the receiving box 201 to quickly take out the material.

[0029] like Figures 1 to 4 As shown, the auxiliary frame assembly 3 includes a support frame 301, a stepper motor 302 and a lead screw 303. The stepper motor 302 is vertically installed on the top of the support frame 301, and the lead screw 303 is installed on the bottom power output end of the stepper motor 302 through a coupling. The support frame 301 is vertically fixed to the top of the stabilizing platform 204, and the support slider 105 is threadedly connected to the lead screw 303. The driving assembly 4 includes a main beam frame 401, a fixed frame 402, a hydraulic push rod 403 and a pressure plate 404. The middle end of the main beam frame 401 is symmetrically connected to the fixed frame 402, and the hydraulic push rod 403 is vertically installed at the bottom of the fixed frame 402. A pressure plate 404 is installed at the bottom of the hydraulic push rod 403. The surface size structure of the pressure plate 404 matches the internal size structure of the forming mold 101. The main beam frame 401 and the fixed frame 402 are welded to each other in a "cross" structure. The support sliders 105 on the left and right sides of the forming mold 101 are threadedly connected to the lead screw 303. When the stepper motor 302 is in operation, it will drive the lead screw 303 connected to its bottom power output end to rotate axially in the vertical direction. As the lead screw 303 rotates, the forming mold 101 will move up and down along the surface of the lead screw 303 through the support slider 105.

[0030] In summary, if Figures 1 to 4 As shown, when the efficient biomass pellet fuel solidification molding device is used, the material to be processed is first injected into the interior of the molding mold 101 through the injection valve 102 installed on one side of the molding mold 101 until an appropriate amount is reached, and then the auxiliary frame components 3 on the left and right sides of the molding component 1 and the driving component 4 directly above the molding component 1 are started at the same time;

[0031] Driven by the stepper motor 302 at the top of the support frame 301, the lead screw 303 connected to the bottom of the stepper motor 302 will rotate axially in the vertical direction, and the support slider 105 threadedly connected to its surface will be driven to move vertically upward under the rotation of the lead screw 303, thereby driving the molding mold 101 connected to the support slider 105 to be vertically lifted;

[0032] At the same time, the hydraulic push rods 403 vertically fixed to the left and right sides of the middle section of the main beam frame 401 by the fixing frame 402 operate simultaneously, and the pressing plate 404 connected to the bottom thereof is pushed down in the vertical direction by the extension and contraction of the structure. Under the above two forces from top to bottom and from bottom to top, the material inside the molding die 101 is squeezed and compressed, and is extruded and formed through the several discharge holes 103 opened at the bottom, and gradually falls into the inside of the receiving box 201 directly below, until the material inside the entire molding component 1 is completely squeezed out from the inside of the receiving box 201;

[0033] Afterwards, the operator can open the discharge door 202 on one side of the receiving box 201 and collect all the molded biomass pellet fuel inside the receiving box 201 for subsequent processing. As the material processing is completed, the entire molding assembly 1 will fall vertically under the drive of the auxiliary frame assembly 3 until the buffer pile 104 is parked on the top surface of the shock absorbing pillar 205, so as to wait for the next round of processing operations.

[0034] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
