Description

Technical Field

[0001] The utility model belongs to the technical field of biomass fuel processing, in particular to automatic drying equipment for biomass fuel. Background Art

[0002] Biomass fuel refers to the burning of biomass materials as fuel, which is generally mainly agricultural and forestry waste. It is mainly different from fossil fuels. Under the current national policies and environmental protection standards, direct combustion of biomass is a high-pollution fuel and is only used in large stoves in rural areas. It is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass molded fuel, which uses agricultural and forestry waste as raw materials, and is made into various molded forms through processes such as crushing, mixing, extrusion, and drying. It is a new type of clean fuel that can be directly burned.

[0003] Firstly, the existing biomass fuel needs to be dried before processing. The existing drying devices are often too dependent on manual labor, and basically cannot be automatically controlled. They cannot adapt well to various processing production lines, resulting in inconvenience in use. Secondly, the existing drying equipment can only perform one continuous drying operation. If the drying is not thorough or continues after reaching the threshold, such equipment will not only result in the drying not reaching the ideal threshold, but also cause energy waste.

[0004] To this end, we propose an automatic drying equipment for biomass fuel. Utility Model Content

[0005] The utility model aims to provide an automatic drying device for biomass fuel, so as to solve the problem that the existing drying equipment can only return for secondary drying if the drying is not thorough after drying, or continues to dry after the drying reaches a threshold, resulting in low energy utilization.

[0006] To achieve the above purpose, the utility model provides the following solutions:

[0007] An automatic drying device for biomass fuel comprises a drying box, a material conveying and lifting device, a first feeding mechanism and a feeding belt, wherein the first drying mechanism is provided at the bottom of the discharge port of the material conveying and lifting device, the first drying mechanism is fixed to the side wall of the drying box, and the discharge port of the first drying mechanism is directly opposite to the upper part of the feeding belt; the discharge port of the first feeding mechanism is connected to the feed port of the second drying mechanism through a connecting plate; the left and right sides of the first feeding mechanism are connected with guide sliders through support plates, the guide sliders are slidably connected with the slide grooves provided on the inner wall of the drying box, the guide sliders are provided with grooves, the grooves are provided with bar teeth, the bar teeth are meshed with active teeth provided on the outer side of the drying box, and the active teeth are driven by an active motor.

[0008] Furthermore, a feed port is provided at the bottom of the material conveying and lifting device, the feed port is in a "C"-shaped structure, and the material conveying and lifting device extends to the bottom of the feed port.

[0009] Furthermore, a discharge port is provided at the discharge end of the conveyor belt, and the discharge end of the conveyor belt extends to the end of the discharge port.

[0010] Furthermore, the material conveying and lifting device and the first feeding mechanism are both conveyor belts connected at both ends. A storage trough is fixedly provided on the outside of the conveyor belt. The cross-section of the storage trough is an "L"-shaped structure. An active roller and two auxiliary rollers are provided inside the conveyor belt. The three rollers support the conveyor belt into a right-angled triangle structure, in which the active roller is connected to an external motor through a rotating shaft.

[0011] Furthermore, the outlets of the first drying mechanism and the second drying mechanism are both provided with humidity sensors, and the humidity sensors are electrically connected to the peripheral control system.

[0012] Furthermore, the material conveying and lifting device and the first material conveying mechanism are both provided with guide support plates on the left and right sides, and the guide support plates are made of elastic and wear-resistant material.

[0013] Furthermore, in order to save the internal space of the drying box, a first tensioning wheel is provided at the feed port of the first drying mechanism. The first tensioning wheel is rotatably connected to the inner wall of the drying box through a rotating shaft. Two first tensioning wheels are provided, and the two first tensioning wheels are symmetrically arranged on the left and right sides of the material conveying and lifting device. The outer side of the first tensioning wheel is in contact with the guide support plate, and the material conveying and lifting device is supported into an inverted "L" shape by the first tensioning wheel, the active roller and the two auxiliary rollers.

[0014] Furthermore, in order to save the internal space of the drying box, a second tensioning wheel is provided on the side of the connecting plate close to the first feeding mechanism. The second tensioning wheel is rotatably connected to the inner wall of the connecting plate through a rotating shaft. The outer side of the second tensioning wheel is in contact with the guide support plate. The first feeding mechanism is supported into an inverted "L" shape by the second tensioning wheel, the active roller and two auxiliary rollers.

[0015] Furthermore, a plurality of second feeding mechanisms are provided on the right side of the first feeding mechanism, and the structure of the second drying mechanism is the same as that of the second feeding mechanism.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] An automatic drying equipment for biomass fuel, after passing through the conveying and lifting device, the material first enters the first drying mechanism for pre-drying, and the pre-dried material falls on the conveyor belt, and then under the conveying action of the conveyor belt, the material is transported to the lower part of the first conveyor mechanism, and then transported to the feeding port of the second drying mechanism by the first conveyor mechanism, and the material after secondary drying by the second drying mechanism falls on the conveyor belt here. At the same time, the humidity sensors provided at the discharge ports of the first drying mechanism and the second drying mechanism transmit the detected data to the control system at any time, and the control system determines whether further drying is required based on the returned data; when the data detected by the control system reaches the threshold, the active motor is started, and the active motor drives the active gear to rotate, and the rotation of the active gear causes the entire first conveyor mechanism to be lifted up, and after the first conveyor mechanism is lifted up, the material on the conveyor belt cannot be transported to the second drying mechanism, and the material on the conveyor belt is directly sent out of the drying box.

[0018] It can be seen that an automatic drying equipment for biomass fuel can dry the material according to the actual situation, solving the problem of over-drying or incomplete drying during the drying process of the existing drying equipment. BRIEF DESCRIPTION OF THE DRAWINGS

The discharge port of the first feeding mechanism 3 is connected to the feed port of the second drying mechanism 9 through a connecting plate 11. After passing through the conveying and lifting device 2, the material first enters the first drying mechanism 8 for pre-drying. The pre-dried material falls onto the feeding belt 5 and then is dried on the feeding belt 5. Under the conveying action, the material is conveyed to the lower part of the first feeding mechanism 3, and then conveyed to the feeding port of the second drying mechanism 9 through the conveying of the first feeding mechanism 3.
