Description

Technical Field

[0001] The sampling device involved in the present utility model, in particular, relates to a double-reduction sampling device applied to the sampling field and cooperating with an ash meter. Background Art

[0002] Electric reduction is a new type of reduction machine developed according to national standard requirements. When working, the reducer makes a horizontal reciprocating motion to cut the material. The grid trough discharges materials in two directions, one side is the test sample, and the other side is the waste material. As the machine continues to operate and cuts the material continuously, several points are regularly taken at different parts of the material, so that the prepared test sample can represent the quality of all the materials fed into the machine.

[0003] Conventional sampling machines are only equipped with a primary reducer or a secondary reducer. When in use, only one coal sample can be collected for testing, and a single sample has no comparability, resulting in the representativeness of the test results not being comprehensive enough. Moreover, once a single set of reduction system fails, the entire machine needs to be shut down for maintenance, resulting in an increase in sampling costs and being unfavorable for ensuring the economic benefits of enterprises. Content of the Utility Model

[0004] Aiming at the above-mentioned prior art, the technical problem to be solved by the present utility model is that conventional sampling machines are only equipped with a single reduction system, and only one coal sample can be collected for testing, making the representativeness of the test results not comprehensive enough. Moreover, once a single set of reduction system fails, the entire machine needs to be shut down for maintenance, which is not convenient for the staff to use.

[0005] To solve the above problems, the present utility model provides a double-reduction sampling device cooperating with an ash meter, including a belt feeder. A belt conveyor is fixedly installed inside the belt feeder. An inlet hopper, an ash meter body, and a primary reducer are fixedly installed on the upper end of the belt feeder in sequence from left to right. A scraper is fixedly sleeved at the output end of the primary reducer. The lower end of the scraper penetrates into the belt feeder, and the upper end of the scraper is located above the belt conveyor. A receiving slot opening matching with the scraper is formed at the upper end of the belt feeder. The lower end of the belt feeder is fixedly connected with an aggregate hopper. The lower end of the aggregate hopper is fixedly connected with a sample collection chute. The right end of the belt feeder is fixedly connected with a discharge hopper. A secondary reducer is fixedly connected to the upper end of the discharge hopper. The output end of the secondary reducer penetrates into the discharge hopper and is fixedly connected with a collection pipe. The lower end of the collection pipe is rotatably connected with a discharge pipe. The end of the discharge pipe away from the collection pipe fixedly penetrates through the discharge hopper and extends to the right end of the discharge hopper. A discharge slot opening matching with the discharge hopper is formed at the corner of the lower end and the right end of the belt feeder.

[0006] In the above double-division sampling device equipped with an ash meter, two division systems are provided. The sample collection chute is made in the form of a riffle, which can obtain three samples simultaneously, making the test results more representative and more conducive to the accuracy of the ash meter data debugging. At the same time, it can serve as a backup and is convenient for the staff to use.

[0007] As a further improvement of the present application, the feed hopper, the aggregate hopper, and the discharge hopper are all connected to the belt feeder.

[0008] As a supplement to the further improvement of the present application, the aggregate hopper is located directly below the scraper, and the longitudinal section of the sample collection chute is in an inverted Y shape.

[0009] As a further improvement of the present application, the discharge hopper includes two communicating U-shaped plates and a fixed box. The U-shaped plates are located below the discharge chute opening, the longitudinal section of the fixed box is in a right-angled trapezoid shape, and the secondary divider is located at the upper end of the fixed box.

[0010] As a further improvement of the present application, the longitudinal section of the discharge pipe is in an L shape, and the included angle at the corner of the discharge pipe is an obtuse angle. The collection pipe includes a straight pipe and two arc pipes with longitudinal sections in right-angled triangle shapes. One of the arc pipes penetrates into the belt feeder at the end far from the straight pipe, and this arc pipe is located below the belt conveyor.

[0011] As another improvement of the present application, a shielding frame is fixedly connected to the upper end of the aggregate hopper. The upper end of the shielding frame is in contact with the lower end of the belt conveyor. Four corners of the upper end of the shielding frame are fixedly connected with baffle plates. The upper ends of the baffle plates are in contact with the inner top wall of the belt feeder. A partition plate is fixedly connected between the two baffle plates, and the corresponding ends of the two partition plates are respectively in contact with the front and rear ends of the belt conveyor.

[0012] In summary, in the actual application process, coal enters the interior of the belt feeder through the feed hopper and falls onto the surface of the belt conveyor. The belt conveyor drives the coal to move to the right. When it reaches below the ash meter body, ash detection is carried out. When it moves to the left side of the scraper, the primary divider is started to drive the scraper to rotate left and right by an appropriate angle with the primary divider as the center, so as to scrape the coal into the aggregate hopper. Then, the coal is divided into two parts through the sample collection chute. The belt conveyor continues to operate and conveys the coal to the left side of the discharge hopper. The secondary divider is started to drive the collection pipe to rotate, and the coal on the belt conveyor falls into the discharge hopper and is discharged. When the collection pipe rotates, part of the coal sample is collected and then discharged through the discharge pipe, so as to obtain three coal samples, making the test results more representative and more conducive to the accuracy of the ash meter data debugging. At the same time, it can serve as a backup and is convenient for the staff to use. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation mode

[0022] The following is a detailed description of the two implementation modes of the present application in conjunction with the accompanying drawings.

[0023] The first implementation mode:

[0024] Figure 1 , Figure 2 and Figure 3Shown: A double-sampling device with an ash analyzer, including a belt feeder 1. A belt conveyor 2 is fixedly installed inside the belt feeder 1. At the upper end of the belt feeder 1, a feed hopper 3, an ash analyzer body 4, and a primary sampler 5 are fixedly installed in sequence from left to right. The ash analyzer body 4 can detect the ash content of coal. A scraper 6 is fixedly sleeved at the output end of the primary sampler 5. The primary sampler 5 drives the scraper 6 to rotate, and can scrape the coal sample into the aggregate hopper 7. The lower end of the scraper 6 penetrates into the belt feeder 1, and the upper end of the scraper 6 is located above the belt conveyor 2. A receiving notch for cooperating with the scraper 6 is provided at the upper end of the belt feeder 1. The lower end of the belt feeder 1 is fixedly connected to an aggregate hopper 7. The lower end of the aggregate hopper 7 is fixedly connected to a sample collection chute 8. The right end of the belt feeder 1 is fixedly connected to a discharge hopper 9. A secondary sampler 10 is fixedly connected to the upper end of the discharge hopper 9. The feed hopper 3, the aggregate hopper 7, and the discharge hopper 9 are all communicated with the belt feeder 1. A receiving notch for cooperating with the scraper 6 is provided at the upper end of the belt feeder 1. The aggregate hopper 7 is located directly below the scraper 6. The longitudinal section of the sample collection chute 8 is in an inverted Y shape. The inverted Y-shaped sample collection chute 8 can divide the coal sample into two parts and collect two samples.

[0025] Figure 4 and Figure 5 Shown: The output end of the secondary sampler 10 penetrates into the discharge hopper 9 and is fixedly connected to a collection pipe 11. The lower end of the collection pipe 11 is rotatably connected to a discharge pipe 12. The end of the discharge pipe 12 away from the collection pipe 11 fixedly penetrates through the discharge hopper 9 and extends to the right end of the discharge hopper 9. A discharge notch for cooperating with the discharge hopper 9 is provided at the corner of the lower end and the right end of the belt feeder 1. The discharge hopper 9 includes two communicating U-shaped plates 91 and a fixed box 92. The U-shaped plate 91 is located below the discharge notch. The longitudinal section of the fixed box 92 is in a right trapezoid shape. The secondary sampler 10 is located at the upper end of the fixed box 92. The longitudinal section of the discharge pipe 12 is in an L shape, and the included angle at the corner of the discharge pipe 12 is an obtuse angle. The collection pipe 11 includes a straight pipe and two arc pipes with longitudinal sections in right triangle shapes. One of the arc pipes penetrates into the belt feeder 1 at the end away from the straight pipe, and this arc pipe is located below the belt conveyor 2.

[0026] During use, coal enters the inside of the belt feeder 1 through the feed hopper 3 and falls onto the surface of the belt conveyor 2. The belt conveyor 2 drives the coal to move to the right. When it reaches below the ash analyzer body 4, ash detection is carried out. When it moves to the left side of the scraper 6, the primary splitter 5 is started to drive the scraper 6 to rotate left and right by an appropriate angle with the primary splitter 5 as the center, so as to scrape the coal into the aggregate hopper 7. Then, the coal is divided into two parts through the sample collection chute 8. The belt conveyor 2 continues to operate and conveys the coal to the left side of the discharge hopper 9. The secondary splitter 10 is started to drive the collection pipe 11 to rotate. The coal on the belt conveyor 2 falls into the discharge hopper 9 and is discharged. When the collection pipe 11 rotates, part of the coal sample is collected and discharged through the discharge pipe 12, so as to obtain three coal samples, making the test results more representative and more conducive to the accuracy of the ash analyzer data debugging. At the same time, it can play a backup role and is convenient for the use of the staff.

[0027] The second implementation mode:

[0028] On the basis of the first implementation mode, this implementation mode adds a shielding frame 13, a baffle 14 and a partition plate 15, and the rest is the same as the first implementation mode.

[0029] Figure 6 and Figure 7 It is shown that a shielding frame 13 is fixedly connected to the upper end of the aggregate hopper 7. The upper end of the shielding frame 13 is in contact with the lower end of the belt conveyor 2. Four corners of the upper end of the shielding frame 13 are fixedly connected with baffles 14. The upper ends of the baffles 14 are in contact with the inner top wall of the belt feeder 1. A partition plate 15 is fixedly connected between the two baffles 14. The corresponding ends of the two partition plates 15 are respectively in contact with the front and rear ends of the belt conveyor 2.

[0030] During use, when the scraper 6 scrapes the coal on the belt conveyor 2 into the aggregate hopper 7, the coal sample is blocked by the shielding frame 13 and the baffle 14, effectively preventing the coal sample from being scraped onto the inner bottom wall of the belt feeder 1. Through the partition plate 15, it effectively prevents the coal sample from being ejected into the inside of the belt conveyor 2 after colliding with the longitudinal inner wall of the belt feeder 1, which is convenient for the use of the staff.

[0031] Combined with the current actual requirements, the above implementation modes adopted by this application, the protection scope is not limited to this. Within the knowledge scope of those skilled in the art, various changes made without departing from the concept of this application still fall within the protection scope of this utility model.
