Description

Technical Field

[0001] This utility model relates to the field of cement clinker production technology, specifically to a raw material homogenization device for cement clinker production. Background Technology

[0002] Cement clinker is a semi-finished product obtained by mixing limestone, clay, and iron-based raw materials in appropriate proportions to form raw meal, burning it until partially or completely melted, and then cooling it. Existing cement clinker production raw material homogenization devices mainly consist of a movable base, a support mounted on the movable base, a lifting mechanism mounted on the support, and a homogenizing mechanism mounted on the lifting mechanism. When homogenizing cement clinker, the device is first moved to the homogenizing cylinder, and the homogenizing component of the homogenizing mechanism is positioned inside the cylinder. Then, cement clinker, slag powder, fly ash, and desulfurized gypsum are added to the homogenizing cylinder, and the mixture is thoroughly mixed under the action of the homogenizing mechanism, thereby achieving the homogenization process of cement clinker.

[0003] While existing cement clinker production raw material homogenization devices can achieve cement clinker homogenization, the large gap between the homogenization mechanism and the external homogenization cylinder during the homogenization process leads to dust emission, resulting in a dirty and messy environment around the device.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0030] like Figures 1-2As shown, a raw material homogenization device for cement clinker production in this embodiment includes a movable base 4. A lifting mechanism 1 is installed on one side of the top of the movable base 4. The lifting mechanism 1 includes a motor 101, a screw 102, a lifting frame 103, and a connecting frame 104. One end of the connecting frame 104 is connected to a cover plate 6. A material homogenizing mechanism 5 is installed in the middle of the cover plate 6. The material homogenizing mechanism 5 includes a motor 501 and a material homogenizing frame 502. A feeding hopper 7 is installed on one side of the top of the cover plate 6. The feeding hopper 7 penetrates the cover plate 6. After the cover plate 6 is placed on the material homogenizing cylinder, the material can be smoothly added to the material homogenizing cylinder through the feeding hopper 7. A dust collection mechanism 8 is installed on the plate 6 on one side of the feeding hopper 7. A shielding mechanism 9 is installed around the bottom edge of the cover plate 6. The dust collection mechanism 8 includes a dust filter plate 801, a dust collection box 802, a negative pressure pump 803, and a dust collection ring 804. The dust collection ring 804 is installed on the upper side of the feeding hopper 7, and the dust collection box 802 is installed on the top of the cover plate 6. The dust filter plate 801 is installed inside the dust collection box 802. The dust filter plate 801 is mainly used to filter the dust in the dust-laden gas sucked into the dust collection box 802 to ensure that the purified gas is easily discharged by the negative pressure pump 803. When the dust filter plate 801 is full of dust, it can... The dust filter screen 801 can be directly pulled out of the dust collection box 802 for cleaning and replacement, thus ensuring the normal filtration function of the dust filter screen 801. The negative pressure pump 803 is located on one side of the dust collection box 802. When the cover plate 6 is placed on the material distribution cylinder, the negative pressure pump 803 will generate a negative pressure in the dust collection box 802. Under the suction of the negative pressure, the dust escaping from the material distribution cylinder is guided to the dust collection box 802 through the dust suction ring 804. After the dust enters the dust collection box 802, it can be filtered by the dust filter screen 801, while the sucked-in air is discharged by the negative pressure pump 803. (Shielding mechanism) 9 includes a telescopic baffle 901 and an elastic retaining ring 902. The telescopic baffle 901 is installed on the outer periphery of the bottom end of the cover plate 6, and the elastic retaining ring 902 is bonded to the bottom end of the telescopic baffle 901. When the cover plate 6 is placed on the material equalization cylinder, the elastic retaining ring 902 is first secured to the outer periphery of the upper end of the material equalization cylinder, and then the cover plate 6 is moved down. The purpose of this design is to ensure the closure of the upper space of the material equalization cylinder when the material equalization rack 502 is long. At the same time, it can also prevent the upper side of the material equalization cylinder from being closed when the cover plate 6 moves up and down relative to the material equalization cylinder during normal material equalization, so as to ensure that the upper side of the material equalization cylinder can always be in a relatively closed state during material equalization.

[0031] like Figures 1-2As shown, in this embodiment, motor 501 is installed at the top center of cover plate 6, and material distribution frame 502 is connected to the power output end of motor 501. Motor 501 is mainly used to provide power for the rotation of material distribution frame 502. Material distribution frame 502 is rotatably connected to cover plate 6 and connected to motor 501 by coupling. After rotation, material distribution frame 502 can mix cement clinker in material distribution cylinder. Dust suction ring 804 is welded to feeding hopper 7 and connected to dust collection box 802 through pipe. Dust escaping from material distribution cylinder can be guided to dust collection box 802 through dust suction ring 804. Negative pressure pump 803 is connected to air intake pipe on dust collection box 802. Air intake on dust collection box 802 is lower than dust filter plate 801. Dust filter plate 801 and dust collection box 802 are slidably fitted.

[0032] like Figures 1-2 As shown, in this embodiment, the lifting frame 103 is welded to the movable base 4. The motor 101 is installed at the top center of the lifting frame 103. The screw 102 is connected to the power output end of the motor 101. The connecting frame 104 is installed on the screw 102. After the motor 101 drives the screw 102 to rotate, the connecting frame 104 can be raised and lowered under the action of threaded transmission. This allows the height of the cover plate 6 to be adjusted while the connecting frame 104 is raised and lowered, ensuring that the cover plate 6 can be smoothly placed on the upper side of the material distribution cylinder. The screw 102 passes through the connecting frame 104 and is threadedly connected to the connecting frame 104. The connecting frame 104 is bolted to the cover plate 6. This bolted connection ensures that the cover plate 6 is raised and lowered synchronously with the connecting frame 104.

[0033] like Figures 1-2 As shown in this embodiment, two push handles 2 are symmetrically installed on one side of the lifting frame 103, and an operation panel 3 is installed on the other side wall of the lifting frame 103. The operation panel 3 mainly controls the orderly operation of motor 101, motor 201 and negative pressure pump 803 by controlling the on and off of the control circuit.

[0034] The specific implementation process of this embodiment is as follows: During material homogenization, the device is first moved to the material homogenizing cylinder. While the screw 102 is rotated by the motor 101 in the lifting mechanism 1, the material homogenizing frame 502 on the material homogenizing mechanism 5 moves down synchronously with the connecting frame 104, ensuring that the material homogenizing frame 502 is located inside the material homogenizing cylinder. Then, cement clinker, slag powder, fly ash, and desulfurized gypsum are added to the material homogenizing cylinder via the feeding hopper 7. Under the action of the motor 501, the material homogenizing frame 502 is rotated to ensure thorough mixing of the cement clinker during rotation, achieving homogenization of the cement clinker. During the processing... Under the action of the negative pressure pump 803, a negative pressure is generated in the dust collection box 802. Under the suction of the negative pressure, the dust escaping from the material distribution cylinder is guided to the dust collection box 802 through the dust suction ring 804. After the dust enters the dust collection box 802, the dust in the dust-laden gas is filtered by the dust filter plate 801. The filtered and purified gas is discharged by the negative pressure pump 803, thereby effectively ensuring the cleanliness of the environment around the device. When the dust filter plate 801 is full of dust, it can be directly pulled out of the dust collection box 802 for cleaning and replacement, thereby ensuring the normal filtration of the dust filter plate 801 in the future.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
