Description

Technical Field

[0001] The present application relates to the technical field of biomass fuels, and in particular to a biomass fuel crushing feed metal identification alarm protection device. Background Art

[0002] Biomass fuel pulverizer is a device used to process biomass raw materials into granular fuel suitable for combustion or other purposes. Biomass fuel includes wood, crop waste, animal manure, etc. After being processed by the pulverizer, these raw materials can improve combustion efficiency, reduce pollutant emissions, and are convenient for storage and transportation.

[0003] The working principle of biomass fuel pulverizer is mainly to use high-speed rotating blades or hammers to hit, shear and tear the raw materials to break them into the required particle size. According to different biomass raw materials and processing requirements, the pulverizer can use different blade structures, speeds, screens and other parameters to achieve the best pulverization effect.

[0004] Biomass raw materials such as bark, branches, and straw are often mixed with metal impurities such as iron blocks and maintenance tools. During the biomass fuel crushing process, the crusher blades, bottom knives, blade pressure plates, and screens will be abnormally damaged.

[0005] Therefore, a biomass fuel crushing feed metal identification alarm protection device is needed. Utility Model Content

[0006] In view of the deficiencies in the prior art, the purpose of this application is to provide a biomass fuel crushing feed metal identification alarm protection device, which is used to solve the problem that other metal substances may be encountered during the crushing process and the staff cannot be aware of it in the first time.

[0007] The above-mentioned purpose of the present application is achieved through the following technical scheme: a biomass fuel crushing feed metal identification alarm protection device, including a conveyor belt group, the conveyor belt group includes a conveyor belt, a driving shaft and a driven shaft, a motor is arranged on the driving shaft, the output end of the motor is fixedly connected to the driving shaft, a metal detection plate is arranged in the middle of the conveyor belt, an alarm that can receive the detection plate signal is arranged on the metal detection plate, and a drive switch is arranged on the motor.

[0008] By adopting the above technical solution, the drive switch is started to drive the motor. When biomass materials such as bark, branches, and straw move along the conveyor belt, when the metal materials therein move along the conveyor belt to the position of the metal detection plate, the alarm will sound an alarm to remind the staff to turn off the drive switch, thereby solving the above technical problem.

[0009] Furthermore, second detection plates extend upward from both ends of the metal detection plate, and the second detection plates are fixed on the metal detection plate and are electrically connected internally.

[0010] By adopting the above technical solution, since the biomass raw materials on the conveyor belt may have metals located away from the conveyor belt when entering the conveyor belt, the second detection plates on both sides will increase the detection range.

[0011] Furthermore, a pusher is provided on one side of the driving switch, and the pusher includes a retractable rod and a receiver, the receiver is electrically connected to the alarm, and the retractable rod is mounted on the receiver.

[0012] By adopting the above technical solution, when the alarm sounds, the electrically connected receiver pushes the retracting rod forward, thereby turning off the front drive switch, so that the staff only needs to remove the metal materials on the conveyor belt, thereby improving work efficiency.

[0013] Furthermore, a contraction spring is provided between the receiver and the contraction rod.

[0014] By adopting the above technical solution, after the retracting rod pushes the driving switch to close, the retracting spring will pull the retracting rod back to its original position.

[0015] Furthermore, an extrusion device is provided at one end of the conveyor belt group, and the extrusion device includes an extrusion plate, an extrusion rod, a rotating wheel and a rolling platform. The extrusion plate is fixedly connected to the extrusion rod, and a rotating rod is provided at one end of the extrusion rod away from the extrusion plate. The rotating rod is rotatably connected to the extrusion rod, and the rotating rod is rotatably connected to the rotating wheel. A rotating shaft is fixedly provided in the middle of the rotating wheel, and a synchronous belt is sleeved on the rotating shaft. The other end of the synchronous belt is sleeved on the driven shaft, and the rolling platform is provided directly below the extrusion plate.

[0016] By adopting the above technical solution, in order to prevent the height of the biomass raw materials on the conveyor belt from being higher than the second detection plate, resulting in the problem of not being detected, the height is reduced by crushing it through the extrusion device, and the synchronous belt drives the rotating shaft, which drives the rotating wheel, drives the rotating rod, and drives the rotating extrusion rod connected to the extrusion rod. The extrusion rod is fixedly connected to the extrusion plate and will move up and down, decompressing the raw materials on the extrusion plate and the crushing platform, and then transferred to the conveyor belt for detection and transportation.

[0017] Furthermore, a rolling conveyor belt group is arranged under the extrusion plate, and the rolling conveyor belt group includes a second driving shaft, a second driven shaft and a second conveyor belt. The rolling conveyor belt group wraps the rolling platform. A gear shaft is fixedly arranged on the driven shaft, and there are only half gears on the gear shaft. A driving gear shaft is fixedly arranged on the second driving shaft, and the driving gear shaft and the gear shaft are meshingly connected.

[0018] By adopting the above technical solution, as the gear shaft on the driven shaft rotates, it intermittently drives the driving gear shaft, thereby intermittently pushing the biomass raw materials on the second conveyor belt, and the above-mentioned extrusion devices cooperate with each other to complete one pressing and one moving.

[0019] Furthermore, a connecting rod is provided on the rolling platform, and the connecting rod is fixedly connected to the rolling platform. The connecting rod extends upward to the height of the extrusion rod and extends toward the extrusion rod, and the extrusion rod is plugged into the connecting rod.

[0020] By adopting the above technical solution, the setting of the connecting rod can allow the extrusion rod to move vertically up and down.

[0021] Furthermore, the second conveyor belt is made of polymer material.

[0022] By adopting the above technical solution, since the second conveyor belt needs to be squeezed, the polymer material can play a certain compression resistance role.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Setting of alarm When the biomass raw materials move along the conveyor belt, when the metal materials therein move along the conveyor belt to the position of the metal detection plate, the alarm will sound an alarm to remind the staff to turn off the drive switch, thereby solving the above technical problems.

[0025] 2. When the alarm sounds, the electrically connected receiver pushes the retracting rod forward, thereby turning off the front drive switch, so that the staff only needs to remove the metal materials on the conveyor belt, thereby improving work efficiency.

[0026] 3. Use the extrusion device to crush it and reduce its height. The synchronous belt drives the rotating shaft, the rotating shaft drives the rotating wheel, drives the rotating rod, drives the rotating extrusion rod, and the extrusion plate fixedly connected to the extrusion rod will move up and down, decompress the raw materials on the extrusion plate and the crushing platform, and then transfer them to the conveyor belt for inspection and transportation.
