[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Example: See Figure 1-5 This utility model provides a technical solution: a biomass pellet fuel cooling device, which is mainly aimed at improving the problems that the cooling devices on the market are often similar in structure, have low cooling efficiency, poor cooling effect, and are time-consuming and labor-intensive. The specific solution is as follows:

[0027] It includes a main cavity 1, an auxiliary cavity 2 and a feeding cavity 3. The upper end surface of the feeding cavity 3 is provided with an inlet 32, and the inlet 32 can facilitate the pouring of biomass pellet fuel. Discharge hole 102 and discharge hole 2 101 are respectively provided on the left and right sides below the main cavity 1. Discharge hole 102 and discharge hole 2 101 can facilitate the discharge of biomass fuel. Among them, the main cavity 1, the auxiliary cavity 2 and the feeding cavity 3 are fixedly installed in sequence, and the main cavity 1, the auxiliary cavity 2 and the feeding cavity 3 are internally connected. A support plate 4 is fixedly installed on the upper end of the feeding cavity 3, and a drive assembly 5 is fixedly installed on the support plate 4. A blowing assembly 6 is provided on the left side of the drive assembly 5, and a diversion assembly 7 is rotatably connected to the middle part of the main cavity 1;

[0028] See also Figure 3The diverter assembly 7 includes a second motor 71, which is connected to the control switch via a wire. The second motor 71 is a reciprocating motor. A swing plate 72 is fixedly mounted on the output shaft of the second motor 71. The swing plate 72 is located within the main chamber 1 and is positioned below the filter 21. The diameter of the swing plate 72 is smaller than that of the main chamber 1. Driven by the second motor 71, the swing plate 72 can swing alternately left and right, thereby facilitating the alternating feeding of biomass pellet fuel, preventing feed blockage, and further improving the cooling efficiency of the biomass pellet fuel.

[0029] See also Figure 1 and Figure 2 The driving component 5 includes a motor 52, which is connected to the control switch through a wire. A spiral piece 51 is fixedly installed on the output shaft of the motor 52, and an adapter component 8 is fixedly installed on the output shafts of the motor 52 and the motor 2 71. After the motor 52 is turned on, the spiral piece 51 can rotate in a circular shape inside the feeding chamber 3, thereby increasing the residual time of the biomass particle fuel inside the feeding chamber 3, making it easier to cool the fuel. The spiral setting allows the biomass particle fuel to fall in batches, making it easier to operate the injection component 6.

[0030] See also Figure 2 The spray assembly 6 includes a piston chamber 61, within which a piston rod 65 is movably connected. A support rod 63 is fixedly mounted at the lower end of the piston rod 65. This support rod 63 is connected to the corresponding sliding sleeve 81 via a connecting rod 66. The support rod 63 has a through hole, and a nozzle holder 64 is fixedly mounted at its lower end, connecting the piston chamber 61 and the support rod 63. An air supply pipe, which communicates with the outside, is located at the upper end of the piston chamber 61. Both the air supply pipe and the connecting pipe 62 are equipped with one-way valves. After the motor 52 is turned on, the spiral blade 51 can rotate in a circular shape inside the feeding chamber 3. Through the setting of the adapter assembly 8 and the connection of the support rod 63, the piston rod 65 reciprocates up and down inside the piston chamber 61, so that air enters the support rod 63 through the connecting pipe 62 and is ejected to the outside from the nozzle seat 64. The biomass pellet fuel that has passed through the spiral feeding can be sprayed and distributed, so that the cooling effect of the biomass pellet fuel is better.

[0031] See also Figure 4 and Figure 5Adapter assembly 8 includes a sliding sleeve 81, the inner side of which is defined by a closed spiral groove 82, which is connected end to end. A sliding block 83 is slidably connected within the closed spiral groove 82, and is fixedly mounted on the output shafts of motor 1 52 and motor 2 71. When motor 1 52 and motor 2 71 are in operation, they provide driving force for the rotation of sliding block 83. Since sliding block 83 continuously slides within closed spiral groove 82, the circular rotation of sliding block 83 causes sliding sleeve 81 to move along the direction set for the output shafts of motor 1 52 and motor 2 71, thereby achieving force transmission.

[0032] In this example, a filter 21 is fixedly mounted at the lower end of the auxiliary cavity 2. This filter 21 is capable of filtering and dispersing the biomass pellet fuel that has fallen after being blown down, allowing for uniform vertical feeding of the biomass fuel and accelerating heat dissipation after the airflow. Simultaneously, a scraper 73 is slidably connected above the filter 21. The scraper 73 is connected to a corresponding sliding sleeve 81 via a second connecting rod 74. When the second motor 71 is turned on, the sliding sleeve 81, through the configuration of the adapter assembly 8, drives the scraper 73 to scrape the filter 21, allowing the biomass fuel to disperse and fall more easily.

[0033] Working principle: When the biomass pellet fuel cooling device is working: start the motor 1 52 and the motor 2 71. After the motor 1 52 and the motor 2 71 are turned on, the transmission of the force can be achieved through the setting of the adapter assembly 8, the connecting rod 1 66 and the connecting rod 2 74. After the motor 1 52 is turned on, the spiral piece 51 rotates to transport the biomass pellet fuel falling from the feed port 32, so that it stays in the feeding chamber 3 for a long time. At the same time, through the connection of the connecting rod 1 66, the piston rod 65 can be driven to reciprocate up and down in the piston chamber 61, so that the air passes through the connecting rod 1 The tube 62 enters the interior of the support rod 63 and is sprayed outward from the nozzle seat 64, which can spray and process the biomass pellet fuel that has passed through the spiral feeding, distribute the spraying, and make the cooling effect of the biomass pellet fuel better; and the start of the motor 2 71 not only allows the swing plate 71 to swing back and forth left and right inside the main cavity 1, but also allows the sliding sleeve 81 to drive the scraper 73 to scrape the filter 21 through the connecting action of the connecting rod 2 74, so that the biomass fuel is easier to disperse and fall, and the biomass pellet fuel falling inside the main cavity 1 alternates from the discharge hole 1 102 and the discharge hole 2 101.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
