Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of biomass pellet production equipment, and in particular to a crushing device for biomass pellet raw materials. Background Technology
[0002] Biomass pellets are granular clean fuels made from agricultural waste (such as straw, sawdust, rice husks, etc.) or forestry residues through processes such as crushing, mixing, drying, and extrusion. They can be burned directly.
[0003] The biomass pellet crushing device can be used to crush agricultural waste; however, the existing biomass pellet crushing device is prone to internal jamming when too much biomass pellets are packed in, which can cause the equipment to malfunction and reduce production efficiency. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a crushing device for biomass pellet raw materials, which can ensure uniform feeding and prevent the machine from jamming.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0006] A device for crushing biomass pellet raw materials includes a main body, and also includes a feed end, a baffle plate, an electric cylinder, a pressure plate, a pressure sensor and a controller;
[0007] The feed end is detachably connected to the upper part of the main body; the baffle plate is removably disposed in the vertical direction of the feed end; electric cylinders are fixedly connected to both ends of the baffle plate; the lower end of the electric cylinder is fixedly connected to the lower part of the feed end; the pressure plate is attached to the inner side of the arc-shaped section of the feed end, and several pressure sensors are provided in the middle; the controller is fixedly connected to the main body; the controller is electrically connected to the pressure sensors and the electric cylinders respectively.
[0008] Furthermore, the pressure plate is an arc-shaped plate, and its periphery is welded to the inner side of the arc-shaped section of the feed end.
[0009] Furthermore, the number of pressure sensors is six.
[0010] Furthermore, the lower discharge end of the main body is a constricted conical cylinder.
[0011] Furthermore, the lower end of the conical cylinder is connected to an auger.
[0012] Furthermore, a support is provided at the lower end of the main body.
[0013] The beneficial effects of this utility model are:
[0014] The pressure is measured in real time by a pressure sensor. When too much raw material is squeezed into the device and exceeds the pressure set by the pressure sensor, the pressure sensor transmits a signal to the controller. The controller then controls the electric cylinder to descend, reducing the amount of raw material entering. When the pressure value measured by the pressure sensor is less than the predetermined value, the controller controls the electric cylinder to rise, increasing the amount of raw material entering. In this way, the crushing chamber in the biomass pellet raw material crushing device is effectively prevented from jamming due to excessive material, thus improving the crushing efficiency.

[0024] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0025] Reference Figure 1-5 As shown, a crushing device for biomass pellet raw materials includes a main body 1, and also includes a feed end 2, a baffle plate 3, an electric cylinder 4, a pressure plate 5, a pressure sensor 6, and a controller 7.
[0026] The feed end 2 is detachably connected to the upper end of the main body 1; the baffle plate 3 is removably installed in the vertical direction of the feed end 2; the two ends of the baffle plate 3 are respectively fixed to the electric cylinder 4; the lower end of the electric cylinder 4 is fixed to the lower part of the feed end 2; the pressure plate 5 is attached to the inner side of the arc section 21 of the feed end 2, and several pressure sensors 6 are provided in the middle; the controller 7 is fixed to the main body 1; the controller 7 is electrically connected to the pressure sensors 6 and the electric cylinder 4 respectively.
[0027] It should be noted that the main body 1 is a conventional scheme for a biomass pellet raw material crushing device in the prior art, and will not be described in detail. It also includes crushing parts and filter screens, which are easily understood by those skilled in the art. The feed end 2 can be connected to a conveyor belt, etc., to facilitate the transportation of biomass pellet raw materials. The baffle plate 3 can block the raw materials. The electric cylinder 4 can drive the baffle plate 3 to rise and fall. The electric cylinder 4 is a commercially available product. Those skilled in the art can select a suitable model for matching according to the size of the feed inlet and the size of the baffle plate 3. The pressure plate 5 can cooperate with the pressure sensor 6. When the material in the crushing chamber of the main body 1 is full and squeezes the pressure plate, the signal is transmitted in real time through the pressure sensor 6. The pressure sensor 6 is a commercially available product. In this application, the RDF-20M is used. Those skilled in the art can match and select according to specific circumstances. The controller 7 can receive the signal from the pressure sensor 6 and control the electric cylinder 4 to drive the baffle plate 3 to rise and fall. This is prior art and will not be described in detail.
[0028] In order to prevent raw materials from getting stuck in the gap of the pressure plate 5, the pressure plate 5 is an arc-shaped plate, and its periphery is welded to the inner side of the arc-shaped section 21 of the feed end 2 to ensure a seal.
[0029] In this application, the number of pressure sensors 6 is set to six, which is sufficient to accurately measure pressure.
[0030] To facilitate uniform material discharge, the lower discharge end of the main body 1 is a constricted conical cylinder 11, and the lower end of the conical cylinder 11 is connected to an auger 8.
[0031] In order to make room for material to be discharged from the lower part, the lower end of the main body 1 is provided with a support 9.
[0032] The working principle of this utility model:
[0033] During operation, raw materials enter the crushing chamber of the main body 1 through the feed end 2 for crushing, and are then fed into the auger 8 from the conical cylinder 11 for uniform discharge. When the crushing chamber of the main body 1 is full of material and squeezes the rear end of the feed end 2, the biomass pellet raw material comes into contact with the pressure plate 5 attached to the inner side of the arc section 21. The pressure sensor 6 measures the pressure in real time. When too much material is squeezed out and exceeds the pressure set by the pressure sensor 6, the pressure sensor 6 transmits a signal to the controller 7. The controller 7 controls the electric cylinder 4 to descend, reducing the amount of raw material entering. When the pressure value measured by the pressure sensor 6 is less than the predetermined value, the controller 7 controls the electric cylinder 4 to rise, increasing the amount of raw material entering. In this way, the crushing chamber in the biomass pellet raw material crushing device is effectively prevented from jamming due to excessive material, thus improving the crushing efficiency.
[0034] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
