Description

Technical Field

[0001] This utility model relates to the field of biomass briquetting technology, and in particular to a conveying device for biomass pellet briquetting. Background Technology

[0002] Both biomass briquettes and biomass pellets are solid fuels processed from biomass resources. Biomass briquettes are solid fuels made by processing and treating certain biomass raw materials and then compressing them into briquettes. Biomass pellets are small, granular solid fuels with a diameter of 4-12 mm, made from biomass raw materials through processes such as crushing, drying, and compression.

[0003] In existing biomass pellet briquettes, after being pressed into shape in a press, they are fed out through a bottom-rotating feeding mechanism. Usually, the feeding mechanism has only one outlet, and a baffle is used to guide the briquettes out of the outlet. The disadvantages of this method are that the briquettes are of different lengths after being discharged from the press, and the feeding is mainly based on the thrust between materials generated by the rotation of the turntable, which easily leads to congestion at the outlet. In addition, the press has many output holes, which reduces the discharge efficiency.

[0004] To address the aforementioned issues, a conveying device for biomass pellet briquettes is proposed. Utility Model Content

[0005] The main purpose of this invention is to provide a conveying device for biomass pellet briquettes, which solves the problems mentioned in the background art.

[0006] The objective of this utility model can be achieved by adopting the following technical solution:

[0007] A conveying device for biomass pellet briquettes includes a conveyor belt body, a receiving hopper is provided directly above the conveyor belt body, discharge opening slots are provided on both sides of the outer wall of the receiving hopper, and a feeding mechanism is provided in the discharge opening slots.

[0008] The feeding mechanism includes a feeding shaft that is rotatably mounted to the outer wall of the receiving hopper via a bushing. A feeding blade that rotates along the discharge opening groove is integrally welded to the outer wall of the feeding shaft. A first pulley is sleeved on the bottom of the feeding shaft. A transmission belt is nested on the first pulley. A second pulley is fitted on the end of the transmission belt away from the first pulley.

[0009] Furthermore, a support platform is integrally welded to the inner wall of the receiving hopper, and a material distribution rotary disk is rotatably mounted on the support platform.

[0010] Furthermore, a drive motor is fixedly installed at the bottom center of the material distribution rotary disc, the second pulley is fixedly sleeved on the output shaft of the drive motor, and the bottom of the drive motor is fixed to the top of the cross plate at the top of the conveyor belt body by screws.

[0011] Furthermore, the feeding blade has an arc-shaped structure, and one end of the feeding blade slides against the inner sidewall of the material distribution rotary disk.

[0012] Furthermore, a conical protective cover is provided around the first pulley, and a feeding hopper is integrally formed around the conical protective cover. The feeding hopper is also fixed to the outer wall of the receiving hopper by screws. The diameter ratio of the first pulley to the second pulley is 2:1.

[0013] Furthermore, the top of the material distribution rotary disc is fitted with a press body via a bearing.

[0014] The beneficial technical effects of this utility model are as follows:

[0015] This invention features an active scraper-type feeding structure with two discharge slots. When the drive motor drives the distribution disc, it simultaneously drives the feeding shafts on both sides to rotate via a transmission belt, a first pulley, and a second pulley. This, in turn, drives the feeding blades to rotate, efficiently scraping the biomass briquettes falling from the distribution disc into the hopper. The briquettes are then conveyed outwards via the bottom conveyor belt. This method greatly improves the feeding efficiency of the briquettes and avoids blockages. Attached Figure Description

[0022] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0023] like Figures 1-4 As shown, this embodiment provides a conveying device for biomass pellet briquettes, including a conveyor belt 1 body, a receiving hopper 2 arranged directly above the conveyor belt 1 body, and discharge opening slots 202 opened on both sides of the outer wall of the receiving hopper 2. A feeding mechanism 4 is arranged in the discharge opening slots 202. The feeding mechanism 4 includes a feeding shaft 406 that is rotatably mounted to the outer wall of the receiving hopper 2 through a bushing. Feeding blades 407 that rotate along the discharge opening slots 202 are integrally welded to the outer wall of the feeding shaft 406. A first pulley 405 is sleeved on the bottom of the feeding shaft 406. A transmission belt 404 is nested on the first pulley 405. A second pulley 408 is installed at the end of the transmission belt 404 away from the first pulley 405.

[0024] In the above structure, the vertical width of the feeding blade 407 is adapted to the vertical width of the discharge opening groove 202.

[0025] A support platform 201 is integrally welded to the inner wall of the receiving hopper 2, and a material distribution rotary disk 403 is rotatably mounted on the support platform 201. A drive motor 402402 is fixedly mounted at the bottom center of the material distribution rotary disk 403, and a second pulley 408 is fixedly sleeved on the output shaft of the drive motor 402402. The bottom of the drive motor 402402 is fixed to the top of the horizontal plate at the top of the conveyor belt 1 body by screws.

[0026] In the above structure, when the drive motor 402 drives the material distribution rotary disk 403 to rotate, it also drives the feeding mechanism 4 on both sides to rotate through the second pulley 408. The rotation direction of the second pulley 408 is the same as the rotation direction of the material distribution rotary disk 403. The bottom of the feeding blade 407 is 0.3cm away from the top of the material distribution rotary disk 403. This setting is to avoid scratching the pressure block.

[0027] The feeding blade 407 has an arc-shaped structure. One end of the feeding blade 407 slides against the inner side wall of the material distribution rotary disk 403. This is designed to prevent the crushed briquette fragments from being squeezed into the gaps and affecting the rotation of the feeding blade 407.

[0028] The first pulley 405 is surrounded by a conical shield 405a. After the top pressing block enters, the conical shield 405a can slide freely to avoid accumulation. The outer periphery of the conical shield 405a is integrally formed with a feeding hopper 401. The feeding hopper 401 fits against the outer wall of the discharge opening groove 202, so that the pressing block and its debris can be swept into the feeding hopper 401. The feeding hopper 401 is also fixed to the outer wall of the receiving hopper 2 by screws. The diameter ratio of the first pulley 405 to the second pulley 408 is 2:1. This setting is to reduce the rotation speed of the feeding blade 407 and avoid damage and deformation of the pressing block when it is swept out due to excessive speed.

[0029] The top of the distributing rotary disc 403 is fitted with a press body 3 via a bearing. It is a device for producing biomass briquettes. Its bottom can support the rotation of the distributing rotary disc 403, and an external support structure is provided to avoid affecting the rotation of the distributing rotary disc 403.

[0030] The working principle of this device is as follows:

[0031] When in use, this device is connected to an external power supply and an external control device.

[0032] After biomass raw materials are fed into the press body 3, they are pressed into long strip-shaped biomass briquettes and squeezed out from the output hole, falling onto the rotating material distribution disc 403 at the bottom. The drive motor 402 drives the first pulleys 405 on both sides to rotate through the second pulley 408 and the transmission belt 404. The rotation speed is 1:2 with the rotation speed of the powder rotating disc. The arc-shaped material-pushing blades 407 sweep the briquettes out of the discharge opening slot 202, fall into the feeding hopper 401, and then fall onto the conveyor belt 1 body for external delivery.

[0033] The above structure can greatly reduce the problem of congestion at the outlet of presses of different lengths, reduce maintenance work, and also increase the discharge speed of the single outlet of the material distribution rotary disc 403, which is conducive to the high-efficiency production and discharge of the press.

[0034] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.

[0035] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
