Description

Technical Field

[0001] The utility model belongs to the technical field of cement production, and in particular relates to an automatic clinker sampling device for a cement enterprise. Background Art

[0002] In the new dry process cement production line, cement clinker is mainly made of limestone, clay and iron raw materials, which are mixed into raw materials in appropriate proportions, burned until partially or completely melted, and then cooled to obtain a semi-finished product. In cement enterprises, cement clinker has an important influence on the quality of cement. In order to ensure the refined control of cement clinker quality, relevant quality inspectors are required to regularly use a shovel to take instantaneous samples on the inclined zipper running on the production line.

[0003] During sampling, the clinker on the surface of the conveying hopper is shoveled, and the clinker samples in the middle and bottom cannot be taken. The clinker sampling is poorly representative. At the same time, quality inspectors are prone to safety accidents such as burns by clinker particles, mechanical strangulation or falling during the sampling process. The work intensity of quality inspectors is high. According to the requirements of safety production regulations, employees on the job are not allowed to directly contact the running equipment. With the development of the cement industry, safety production and product quality have become the priority. Product testing is particularly important. The accuracy of the test results is an important basis for timely system adjustments. However, the existing automatic sampling device has a relatively complex structure, high cost and is difficult to maintain in the later stage. Utility Model Content

[0023] 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.

[0024] Example 1:

[0025] See also Figures 1-6 As shown, a cement enterprise clinker automatic sampling device comprises:

[0026] Material guide 1;

[0027] The oblique zipper hopper 2 is arranged outside the material guide 1;

[0028] The valve mechanism 3 is arranged on the outer wall of one side of the bottom plate of the oblique zipper hopper 2. The valve mechanism 3 includes a fixed shaft 301, a first bearing 302 and a baffle 303. The outer wall of the fixed shaft 301 is installed with a first bearing 302, and the outer wall of the first bearing 302 is rotatably installed with a baffle 303. The upper outer wall of the baffle 303 is fitted with a sealing gasket 304. The lower end of the guide 1 is provided with a discharge port 101, and the lower end of the valve mechanism 3 is installed with a collector 4. Support frames 5 are installed on both sides of the inner wall of the collector 4. The bottom end of the collector 4 is installed with an external shell 6. The upper outer walls of the two support frames 5 are respectively installed with a first limit rod 501 and a second limit rod 502. The sealing gasket 304 is connected to the lower outer wall of the oblique zipper hopper 2. A limiter 305 is installed on the right side of the valve mechanism 3. The baffle 303 adopts a fan-shaped design, and the position of the baffle 303 corresponds to the position of the discharge port 101.

[0029] Specifically, the sealing gasket 304 can ensure the sealing between the baffle 303 and the oblique zipper hopper 2, preventing the material inside the material guide 1 from flowing out through the gap. A limit card is provided on the left side of the limiter 305, which can ensure the relative stability of the baffle 303 at the lower end of the oblique zipper hopper 2. The right side of the limiter 305 is designed as an opening, which can ensure that the baffle 303 can be opened smoothly. The size of the baffle 303 is larger than the inner wall of the discharge port 101.

[0030] As can be seen from the above, the material guide 1 is installed at the bottom of a certain oblique zipper hopper 2 of the oblique zipper machine, and an appropriate number of material guides 1 can be selected according to the inspection needs, and they can be evenly installed at the bottom of the oblique zipper hopper 2 of each conveyor frame. A valve mechanism 3 is installed on one side of the outer wall of the bottom plate of the oblique zipper hopper 2. The baffle 303 of the valve mechanism 3 is larger than the inner wall of the discharge port 101. The oblique zipper hopper 2 will drive the material guide 1 to move synchronously during the movement from back to front. When the baffle 303 contacts the first limit rod 501 on its right side, since the first limit rod 501 is fixed by the support frame 5, the baffle 303 will rotate in a circle through the first bearing 302 under the obstruction of the first limit rod 501 and expose the discharge port 101. At this time, the inside of the material guide 1 The clinker falls into the collector 4 through the discharge port 101, thereby completing the purpose of sampling the clinker. When the clinker sample in the guide 1 falls completely into the collector 4, as the oblique chain hopper 2 continues to move forward, the second limit rod 502 contacts the left outer wall of the baffle 303, and since the second limit rod 502 is fixed to it through the support frame 5, it pushes the baffle 303 to rotate circumferentially and reset through the first bearing 302, and contacts and seals with the discharge port 101, ensuring the blocking effect of the baffle 303 on the discharge port 101. The clinker inside the collector 4 can enter the receiving box 11 inside the external shell 6 through the discharge pipe, which makes it convenient for the staff to collect the material, and the clinker in the oblique chain hopper 2 is transported as usual.

[0031] Example 2:

[0032] refer to Figure 3 and Figure 6 As shown, the first limiting rod 501 is installed at the front of the upper end of the support frame 5, and the second limiting rod 502 is installed at the rear of the upper end of the support frame 5. The outer walls of the first limiting rod 501 and the second limiting rod 502 are both installed with a second bearing 503 and a third bearing 504. An opening is provided in the middle and lower part of the front of the external shell 6, and an internal plate 7 is provided inside the external shell 6. Several fan groups 8 are equidistantly provided inside the internal plate 7. The left end of the internal plate 7 is fixedly connected to the filter window 9, and the right end of the internal plate 7 is fixedly connected to the heat dissipation window 10. A material receiving box 11 is provided below the external shell 6, and the material receiving box 11 is located below the above-mentioned opening. A handle 12 is provided in the middle of the front of the material receiving box 11.

[0033] As can be seen from the above, the filter window 9 intercepts particles in the falling process to prevent them from damaging the fan group 8, and the heat dissipation window 10 facilitates the dissipation of heat. The clinker temperature in the receiving box 11 is relatively high, and it is cooled by the fan group 8 to prevent the staff from being scalded by clinker particles during the sampling process, thereby improving the safety of the sampling work.
