Description

Technical Field

[0001] The utility model belongs to the technical field of cement clinker processing, and particularly relates to an automatic sampling machine for cement production clinker. Background Art

[0002] Cement clinker is a semi-finished product of cement. The quality of cement directly affects the quality of the finished cement. Therefore, during the production process of clinker, it is necessary to take samples at multiple time periods within 24 hours and conduct physical and chemical analyses on the samples in order to timely adjust the batching and thermal process.

[0003] Currently, the sampling in cement plants still stays in the simple stage of manual sampling. Not only is the influence of human factors relatively large, but also the representativeness of sampling is difficult to guarantee. At the same time, although the clinker on the inclined zipper has been rapidly cooled by the grate cooler, the temperature is still relatively high. Manual sampling requires wearing heat-insulating gloves, which not only causes harm from high-temperature radiation and dust, but also poses a risk of being caught by the trough bucket conveyor. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is:

[0005] When sampling cement clinker in the prior art, manual sampling is adopted. On the one hand, it is not representative. On the other hand, manual workers are harmed by high temperature and dust, and there are also potential safety hazards.

[0006] To solve the above technical problem, the technical solution proposed by the utility model is: an automatic sampling machine for cement production clinker, including a baffle, a driving component and a material taking device. An outer pipe is bolted to the baffle. The driving component is fixedly connected to the outer pipe through flange connection of a connecting plate. An inner pipe is welded on the other side of the baffle at the corresponding position of the outer pipe. The material taking device is arranged in the inner pipe and is rotationally connected to the driving component.

[0007] Further, a triangular material guiding groove is arranged between the inner pipe and the baffle. An inclined discharge pipe is arranged at the position corresponding to the bottom of the baffle and the bottom of the material guiding groove. A material scooping door connected by bolts is arranged between the discharge pipe and the outer pipe. An outlet groove is arranged on the part of the inner pipe located in the material guiding groove.

[0008] Further, the driving component includes a motor, a worm, a worm gear and a screw rod. The worm and the worm gear are both rotatably installed in a machine shell. The worm and the worm gear are meshed and connected. The screw rod penetrates through the worm gear and is threadedly connected to the worm gear. The output shaft of the motor is fixedly connected to the worm. A limiting groove is opened on the screw rod. A limiting frame penetrating through the limiting groove is arranged on the inner wall of the outer pipe.

[0009] Further, a material taking groove is provided on the material taker, and a guiding groove is provided on the outer wall of the material taker. The guiding groove is provided in two sections. One section is parallel to the axis of the material taker, and the other section is helically arranged around the axis of the material taker by 180 degrees. A guiding block embedded in the guiding groove is provided at the end of the inner tube.

[0010] Further, the material taker is rotatably connected to the end of the screw rod away from the worm gear.

[0011] The beneficial effects achieved by the present utility model with the above structure are as follows:

[0012] By arranging the inner tube and the material taker inside the grate cooler, and the driving assembly and the outer tube outside the grate cooler, the baffle acts as a maintenance door. Driven by the driving assembly, the material taker can realize material taking and discharging, achieving the automatic material taking function and reducing the physical and mental harm and safety hazards caused by manual labor.

Together with the embodiments of the present utility model, they are used to explain the present utility model, and do not constitute a limitation to the present utility model. Detailed Embodiments

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments; based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 shown, an automatic sampling machine for cement production clinker proposed by the present utility model includes a baffle 1, a driving assembly 3 and a material collector 5. The baffle 1 is installed on the grate cooler, replacing the inspection door of the grate cooler. An outer pipe 2 is bolted to the baffle 1. The driving assembly 3 is fixed to the outer pipe 2 through a connecting plate flange connection. An inner pipe 4 is welded on the other side of the baffle 1 at the corresponding position of the outer pipe 2. The material collector 5 is arranged in the inner pipe 4 and is rotationally connected to the driving assembly 3.

[0023] As Figure 1-3 shown, a triangular material guiding groove 6 is provided between the inner pipe 4 and the baffle 1. An inclined discharge pipe 7 is provided at the position corresponding to the bottom of the baffle 1 and the bottom of the material guiding groove 6. A material scooping door 8 bolted to the outer pipe 2 is provided between the discharge pipe 7 and the outer pipe 2. A discharge groove 9 is provided at the part of the inner pipe 4 located in the material guiding groove 6.

[0024] Thus, under the drive of the driving assembly 3, the material collector 5 can take materials and move into the inner pipe 4 to pass the clinker through the discharge groove 9, and finally fall into the collection container through the discharge pipe 7.

[0025] After the material scooping door 8 is disassembled, manual auxiliary unloading can be carried out. An auxiliary pipe fitting can also be connected to the discharge pipe 7 to assist in discharging materials.

[0026] In order to drive and realize the traction of the material collector 5, the driving assembly 3 includes a motor 10, a worm 11, a worm gear 12 and a screw 14. The worm 11 and the worm gear 12 are both rotatably installed in the machine housing 13. The worm 11 and the worm gear 12 are meshed with each other. The screw 14 penetrates through the worm gear 12 and is threadedly connected to the worm gear 12. The output shaft of the motor 10 is fixed to the worm 11. A limiting groove 15 is provided on the screw 14. A limiting frame 16 that penetrates the limiting groove 15 is provided on the inner wall of the outer pipe 2. In this way, it can be ensured that the screw 14 does not rotate relative to the outer pipe 2, so as to realize that when the worm gear 12 rotates, the screw 14 is driven to generate displacement to traction the material collector 5. The material collector 5 is rotationally connected to the end of the screw 14 away from the worm gear 12.

[0027] Among them, a material taking groove 17 is provided on the material taking device 5, and a guiding groove 18 is provided on the outer wall of the material taking device 5. The guiding groove 18 is provided in two sections. One section is parallel to the axis of the material taking device 5, and the other section is helically arranged around the axis of the material taking device 5 by 180 degrees. A guiding block 19 is provided at the end of the inner tube 4 and is embedded in the guiding groove 18. Since the material taking device 5 is rotatably connected to the driving assembly 3, when the screw 14 is pulled, after the guiding block 19 horizontally moves into the inner tube 4 along the first section of the guiding groove 18, the guiding block 19 continues to move helically along the second section. At this time, the material taking device 5 rotates. After the material taking groove 17 coincides with the guiding block 19, the clinker drops and discharges from the discharge pipe 7 along the material guiding groove 6.
