The calcining chamber 1 is suitable for storing and calcining coal, and the detecting chamber 2 is suitable for collecting and cooling ash left after calcining so as to facilitate subsequent detection. The above components are described in detail below.
The calcining cavity 1 is arranged in the device body, and the whole calcining cavity 1 is in a bucket shape, so that the bottom wall of the calcining cavity 1 is lower than the two side walls. The calcining cavity 1 is opened at one side, and after the opening of the calcining cavity 1 is opened, an operator can put a sample of coal into the calcining cavity 1 and place the sample on the bottom wall of the calcining cavity 1. After the coal is placed, the calcining cavity 1 heats the coal, so that the calcining cavity 1 is promoted to burn, and finally, after the coal is burnt, the remaining substances are ash of the coal.
The detection chamber 2 is provided inside the device body, and the detection chamber 2 is provided below the calcination chamber 1. The detection cavity 2 is internally provided with a detection part 3, the detection part 3 is positioned under the bottom wall of the calcining cavity 1, the detection cavity 2 is communicated with the calcining cavity 1, and specifically, one side of the detection cavity 2 is provided with a channel communicated with the section of calcining money.

The air in the detecting section 3 can be blown into the calcination chamber 1, and after the air enters the detection chamber 2, the air can be introduced into the calcination chamber 1 through the passage. With the above arrangement, when the coal is burned in the burning chamber 1, the detecting portion 3 is configured to completely burn the coal by introducing air into the burning chamber 1 through the detecting chamber 2. After the coal in the calcining cavity 1 is calcined, the bottom wall of the calcining cavity 1 is opened so that ash content of the coal falls into the detecting part 3, and the detecting part 3 performs blowing cooling on the ash content. After the ash is cooled, the detecting part 3 continues to blow, and the air beats the ash attached to the detecting part 3, so that the ash is gathered at a low-lying part at the bottom of the detecting part 3.
In order to achieve the above effect, the detecting portion 3 includes a ventilation unit 31 and a collection unit 32. The collection assembly 32 is arranged below the ventilation assembly 31, the collection assembly 32 and the ventilation assembly 31 are arranged in parallel, the collection assembly 32 and the ventilation assembly 31 are both rotationally connected with two sides of the device body, and the ventilation assembly 31 is linked with the collection assembly 32.

With the above arrangement, when the inside of the calcination chamber 1 is subjected to coal calcination, the ventilation unit 31 blows air into the detection chamber 2 and ventilates the calcination chamber 1 through the passage. When the air pump blows air to the ventilation assembly 31, the ventilation assembly 31 can blow air to the calcining cavity 1 or blow air to the collecting assembly 32, so that coal is completely combusted. The ash is suitable for collecting in the collection assembly 32, after the bottom wall of the calcining cavity 1 is opened, the air pump stops ventilation, and the ash in the calcining cavity 1 can pass through the ventilation assembly 31 to enter the collection assembly 32. The ventilation assembly 31 can rotate circumferentially, thereby driving the collection assembly 32 to rotate synchronously. When the ventilation assembly 31 rotates to one side to be communicated with the collecting assembly 32, the ventilation assembly 31 blows air into the collecting assembly 32 to cool ash in the collecting assembly 32. When the ventilation assembly 31 rotates to the other side to be communicated with the collection assembly 32, the ventilation assembly 31 continuously blows air into the collection assembly 32, and the air pushes the collection assembly 32 to shake, so that ash adhered to the inner wall of the collection assembly 32 falls to the bottom of the collection assembly 32.

The first ventilation pipe 311 and the second ventilation pipe 312 are arranged in parallel, and the first ventilation pipe 311 and the second ventilation pipe 312 are both rotatably connected with the device body. One end of the first ventilation pipe 311 and one end of the second ventilation pipe 312 are connected through a belt, and when the belt rotates circularly, the first ventilation pipe 311 and the second ventilation pipe 312 can be driven to rotate synchronously. The first ventilation pipe 311 and the second ventilation pipe 312 are provided with gaps, and the first ventilation pipe 311 and the second ventilation pipe 312 are arranged on two sides above the collecting assembly 32 in a mirror image mode, so that ash on the bottom wall of the calcining cavity 1 can fall into the collecting assembly 32 through the gaps between the first ventilation pipe 311 and the second ventilation pipe 312.
In order to make the first ventilation pipe 311 and the second ventilation pipe 312 blow out and communicate with the collection assembly 32, a first ventilation port 3111 is provided on the side wall of the first ventilation pipe 311, and a second ventilation port 3121 is provided on the side wall of the second ventilation pipe 312. The first vent 3111 is slidable radially along a side wall of the first vent pipe 311, and the second vent 3121 is slidable along a side wall of the second vent pipe 312. In addition, two valve plates 313 are mirror images disposed in the first air port 3111 and the second air port 3121, the valve plates 313 are hinged to the inner walls of the first air port 3111 and the second air port 3121, and one ends of the two valve plates 313 away from the side walls of the first air port 3111 and the second air port 3121 are abutted. When the air pump ventilates in the first ventilation pipe 311, the air in the first ventilation pipe 311 pushes the valve diaphragm plate 313 to open outwards. Meanwhile, when the collecting assembly 32 rotates to be connected with the first ventilation pipe 311 and the second ventilation pipe 312, the collecting assembly 32 pushes the valve plates 313 in the first ventilation pipe 311 and the second ventilation pipe 312 to open outwards and inwards, so that the collecting assembly 32 is communicated with the first ventilation pipe 311 and the second ventilation pipe 312.
The structure of the collecting assembly 32 is specifically described below, and the collecting assembly 32 includes a linkage tube 321. One end of the first vent pipe 311 is provided with a driving gear, and the corresponding end of the linkage pipe 321 is provided with a driven gear, wherein the driving gear is meshed with the driven gear, so that the linkage pipe 321 is driven to synchronously rotate when the first vent pipe 311 rotates. A heat dissipation baffle 322 is disposed in the linkage pipe 321, and the heat dissipation baffle 322 divides the collecting pipe 329 into a cooling cavity 323 and a collecting cavity 324, wherein the cooling cavity 323 and the collecting cavity 324 are communicated with the outside of the device body. A collection tube 329 is disposed within the collection chamber 324, the collection tube 329 being adapted to contain ash therein. The linkage pipe 321 is open towards one side of the calcining chamber 1, and the collecting pipe 329 is positioned at the opening of the linkage pipe 321 and is correspondingly provided with a collecting opening 325. The collection port 325 is provided between the gaps of the first ventilation pipe 311 and the second ventilation pipe 312. With the above arrangement, ash from the bottom wall of the calcination chamber 1 passes through the gap between the first ventilation pipe 311 and the second ventilation pipe 312 and enters the collection pipe 329 through the collection port 325. When the linkage pipe 321 is rotated to one side to insert the first vent pipe 311, the vent assembly 31 vents air into the cooling chamber 323 to cool the cooling chamber 323 to the collecting pipe 329. When the linkage tube 321 is rotated into communication with the second vent tube 312, the vent assembly 31 vents air into the collection chamber 324 to cause the air to push the collection tube 329 into shaking.
In order to achieve the above effect, the side wall of the cooling cavity 323 is provided with a first plugging tube 3231, and the side wall of the collecting cavity 324 is provided with a second plugging tube 3241. When the first plug pipe 3231 is inserted into the first air port 3111, the first air pipe 311 is communicated with the cooling chamber 323; when the second insertion tube 3241 is inserted into the second air vent 3121, the second air vent tube 312 is in communication with the collection chamber 324.
In order to control the opening and closing of the collection port 325, an electromagnetic valve 3251 is disposed in the collection port 325, and the electromagnetic valve 3251 is attached to both side walls of the opening of the linkage pipe 321. Through the setting of solenoid valve 3251 for the ash content is in the in-process of getting into collecting pipe 329, solenoid valve 3251 sets up, and solenoid valve 3251 control collection mouth 325 is opened, so that the ash content can get into in the collecting pipe 329, and in linkage pipe 321 pivoted in-process, solenoid valve 3251 control collection mouth 325 is closed, in order to avoid the ash content to pour through collection mouth 325 in linkage pipe 321 rotation in-process.
To avoid ash entering the gap between the linkage tube 321 and the collection tube 329 during entry into the collection port 325. The two sides of the collecting port 325 are provided with organ pipes 326, one end of each organ pipe 326 is fixed to the outer wall of the collecting pipe 329, and the other end is fixed to the inner wall of the linkage pipe 321. By providing the organ pipe 326, the gap between the box-linked pipes 321 of the collecting pipe 329 can be closed and ash can be guided into the collecting port 325. Meanwhile, the organ pipe 326 has certain elasticity, when the electromagnetic valve 3251 is arranged upwards, the organ pipe 326 pushes the collecting pipe 329 to be wholly far away from the inner wall of the linkage pipe 321, so that the collecting pipe 329 is attached to the heat dissipation partition 322 towards the side wall of the heat dissipation partition 322, and when the air in the cooling cavity 323 is in the inner cylinder, the heat of the collecting pipe 329 is guided through the heat dissipation partition 322.
In order to collect the cooled ash conveniently, a recovery plate 3252 is fixed on one side of the electromagnetic valve 3251 away from the calcining chamber 1, the recovery plate 3252 is arc-shaped, two ends of the recovery plate 3252 are elastically connected with the inner wall of the collecting pipe 329, and specifically, two ends of the recovery plate 3252 are connected with the collecting pipe 329 through springs.
In order to further collect ash adhered to the inner wall of the collecting pipe 329, an adjusting spring 327 and a sliding plate 328 are sequentially provided on one side of the collecting pipe 329 toward the second socket pipe 3241. When the shape of the collecting pipe 329 is designed that the electromagnetic valve 3251 faces upwards, one side of the sliding plate 328 is a depression of the collecting pipe 329, and meanwhile, two sides of the sliding plate 328 incline towards the sliding plate 328, so that ash enters the collecting pipe 329 and naturally gathers towards the sliding plate 328 under the action of gravity. The two ends of the adjusting spring plate 327 are fixed to the inner wall of the collecting pipe 329, and the two ends of the sliding plate 328 are slidably connected to the inner wall of the collecting pipe 329. Through the above arrangement, when the second plug tube 3241 is inserted into the second air vent 3121, the electromagnetic valve 3251 faces downwards, air in the second air vent tube 312 is ejected to the adjusting spring 327 through the second air vent 3121, and the air blows the adjusting spring 327 to swing along the thickness direction, so that the adjusting spring 327 flaps the sliding plate 328, and the sliding plate 328 slides along the inner wall of the collecting pipe 329 to shake off ash attached to the sliding plate 328. In addition, the air blows the collecting pipe 329 as a whole against the elastic force of the organ pipe 326 to shake off ash adhering to the inner wall of the collecting pipe 329, and the ash is collected on the recovery plate 3252.
