Description

Technical Field

[0001] This utility model relates to the field of blast furnace raw material sampling technology, specifically to a screening and sampling device for blast furnace raw materials. Background Technology

[0002] In the production of sintered ore, it is necessary to periodically extract sintered ore samples for chemical composition and physical property testing. Based on the test results, the sintering process parameters, such as the raw material ratio, are adjusted to ensure product quality. For a long time, sintered ore sampling has been done manually. During sampling, workers use simple long-handled shovels and clamping tools to extract sintered ore samples. Although the existing blast furnace raw material sampling devices can perform sampling operations, they do not have screening functions. Sampling is accompanied by dust, which can easily contaminate the testing site and is detrimental to the health of the staff. Moreover, in order to sample the raw materials at the required location, they are usually equipped with long operating handles, which take up a lot of space and are not convenient to place. Utility Model Content

[0003] In view of the problems of the prior art, the purpose of this utility model is to provide a screening and sampling device for blast furnace raw materials, so as to solve the technical problems such as the sampling operation not having a screening function, dust being generated during sampling, and the sampling device occupying a large space and being difficult to store.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A sieving and sampling device for blast furnace raw materials includes a sampling barrel and a top plate. A support plate is provided at the bottom of the sampling barrel. An insertion hole is provided on each side of the support plate. A screen is provided inside the sampling barrel. An elastic insert is fixedly installed on each side of the lower surface of the screen. A locking block is provided on the elastic insert. The insertion hole matches the elastic insert and the locking block.

[0006] Preferably, one side of the sampling bucket is movably connected to one end of the second operating rod, and the other end of the second operating rod is provided with a connecting groove. A limit hole is provided on one side of the connecting groove. A first operating rod is hinged to the edge of the other end of the second operating rod. A connecting block is provided on the first operating rod, and two limit grooves are provided on the connecting block. An installation groove is provided on the first operating rod. A spring is fixedly installed at the bottom of the inner cavity of the installation groove. A connecting post is fixedly connected to the upper end of the spring. A fixing block is fixedly connected to the upper end of the connecting post. A limit post matching the limit groove is provided on the lower surface of the fixing block. The lower end of the limit post is inserted into the limit groove through the limit hole.

[0007] Preferably, a T-shaped guide rail is provided at the center of the lower surface of the top plate, a hanging rod is provided at the edge of the sampling bucket, a bracket is provided at one end of the hanging rod, a movable seat is fixedly installed on the bracket, and the movable seat is movably connected to the T-shaped guide rail through rollers.

[0008] Preferably, a threaded sleeve is provided on one side of the sampling bucket, and a threaded head is provided at one end of the second operating rod. The sampling bucket is connected to the second operating rod through the threaded sleeve and the threaded head.

[0009] The beneficial effects of this utility model are as follows:

[0010] 1. This utility model discloses a screening and sampling device for blast furnace raw materials. A screen is installed inside the sampling barrel. By shaking the sampling barrel on the T-shaped guide rail, dust can be screened off. At the same time, the screen is set on the upper surface of the support plate. By moving the locking block, the elastic insert bends. Pushing the locking block upwards, the elastic insert connected to the locking block disengages from the inner cavity of the insertion hole of the support plate, thereby facilitating the disassembly of the screen and making it easy to replace or clean the screen as needed.

[0011] 2. This utility model discloses a screening and sampling device for blast furnace raw materials. The second operating rod is connected to the sampling barrel by a threaded head and a threaded sleeve, which facilitates the removal of the second operating rod from the sampling barrel. At the same time, by pulling up the fixing block on the second operating rod, the connecting column connected to the fixing block is stretched by the spring, causing the limiting column to disengage from the inner cavity of the limiting groove. This allows the connecting block to be rotated out of the inner cavity of the connecting groove, so that the first operating rod and the second operating rod can be folded together, thereby reducing the length, reducing the space occupied, and facilitating placement.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 , Figure 7 The utility model illustrates a sieving and sampling device for blast furnace raw materials, comprising a top plate 7 and a sampling barrel 3. A T-shaped guide rail 4 is positioned at the center of the lower surface of the top plate 7. A hanging rod 5 is positioned on the symmetrical edge of the sampling barrel 3, and a bracket 6 is positioned at one end of the hanging rod 5. A movable seat 9 is fixedly installed on the bracket 6, and the movable seat 9 is movably connected to the T-shaped guide rail 4 via rollers 8. A screen 13 is installed inside the sampling barrel 3. A first operating lever 1 and a second operating lever 2 are positioned on one side of the sampling barrel 3. The sampling personnel hold the first operating lever 1 and the second operating lever 2 and shake the sampling barrel 3 back and forth, causing the hanging rod 5, the bracket 6, and the movable seat 9 to move back and forth on the T-shaped guide rail 4 via the rollers 8. The sample shakes back and forth on the screen 13, which can effectively shake off the floating soil, dust, and some impurities on the sample, thereby achieving the purpose of preliminary sample cleaning.

[0022] like Figure 6 The utility model illustrates a screening and sampling device for blast furnace raw materials. A support plate 17 is provided at the bottom of the sampling barrel 3. Each side of the support plate 17 has an insertion hole 24. Four elastic inserts 22 penetrate the insertion holes 24 on the lower surface of the screen 13. One end of each elastic insert 22 is fixedly fitted with a locking block 23 that engages with the insertion hole 24. The locking block 23 has a right-angled triangular structure and is integrally formed with the elastic insert 22. By bending the locking block 23, the elastic insert 22 is elastically bent. Simultaneously, the locking block 23 is pushed upwards, causing the elastic insert 22 and locking block 23 to slide out of the insertion hole 24. The screen 13 then disengages from the insertion hole 24 on the support plate 17, facilitating the disassembly of the screen 13 and allowing for replacement or cleaning as needed.

[0023] like Figure 2 , Figure 4 , Figure 5 The utility model shown discloses a screening and sampling device for blast furnace raw materials. A connecting groove 11 is provided at the other end of a second operating rod 2. A limiting hole 25 is provided on the connecting groove 11. A first operating rod 1 is rotatably connected to one end of the second operating rod 2. A connecting block 12 is provided at one end of the first operating rod 1, engaging with the connecting groove 11. Limiting grooves 18 are symmetrically provided on the upper surface of the connecting block 12. An installation groove 19 is provided on the first operating rod 1. A spring 20 is fixedly installed at the bottom of the inner cavity of the installation groove 19. A connecting column 21 is fixedly connected to the upper end of the spring 20. A fixing block 10 is fixedly connected to the upper end of the connecting column 21. Two limiting posts 16, which communicate with the connecting groove 11, are fixedly installed on the lower surface of the device. The lower ends of the limiting posts 16 are inserted into the limiting groove 18 through the limiting holes 25. When the sampling personnel pull the fixing block 10 upward, the connecting post 21 connected to the fixing block 10 is pulled upward. The spring 20 connected to the connecting post 21 is stretched inside the mounting groove 19, causing the limiting post 16 to disengage from the inner cavity of the limiting groove 18 and be pulled out from the limiting hole 25. This allows the connecting block 12 to be rotated out from the inside of the connecting groove 11, so that the first operating rod 1 and the second operating rod 2 can be folded, thereby reducing the length, reducing the space occupied, and facilitating placement.

[0024] like Figure 3 The utility model shown is a screening and sampling device for blast furnace raw materials. A threaded sleeve 14 is provided on one side of the sampling barrel 3, and a threaded head 15 is provided at one end of the second operating rod 2. The sampling barrel 3 is connected to the second operating rod 2 through the connection of the threaded sleeve 14 and the threaded head 15. The sampling personnel hold the second operating rod 2 and can remove the sampling barrel 3 from the second operating rod 2 and the first operating rod 1 by rotating the threaded head and the threaded sleeve 14 on the sampling barrel 3 in the opposite direction, so as to facilitate the storage of the operating rod.

[0025] When in use, the sampling personnel can screw the first operating rod 1 and the second operating rod 2 together onto the sampling bucket 3. During sampling, the length of the operating rod can also be adjusted according to the distance of the sample. The obtained sample is sieved through the sieve 13 in the sampling bucket 3. After sampling is completed, the operating rod is screwed off again, and the first operating rod 1 and the second operating rod 2 are folded and placed to reduce the space occupied.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
