Description

Technical Field

[0001] The utility model relates to the technical field of sponge iron cleaning, in particular to a sponge iron inner hole cleaning device. Background Art

[0002] During the sponge iron production process, iron oxide scale is mixed with carbon powder and desulfurizer limestone and then calcined and reduced at high temperature. This leaves the surface of the sponge iron out of the tank with a large amount of reduced carbon powder and limestone powder, whose main components are SiO2, Caco3, and CaS. These substances are insoluble in hydrochloric acid and are called acid-insoluble matter. If mixed with iron powder, they will reduce the quality of the reduced iron powder. Therefore, cleaning the sponge iron is a key process in the production of reduced iron powder. At present, the outer diameter of the sponge iron produced by our company is cleaned with a wire brush during the sponge iron's descent process, but the inner hole is still cleaned manually after the sponge iron is flattened. This method has the following disadvantages:

[0003] 1. The inner hole is not cleaned thoroughly enough and the cleaning effect is poor.

[0004] 2. The workers are very labor-intensive, and the cleaning process generates a lot of dust, resulting in a poor working environment and low safety.

[0005] 3. Workers can only clean one sponge iron at a time, and it takes a long time to clean one, which is time-consuming and labor-intensive, and has low work efficiency.

[0006] In the prior art, for example, Chinese patent publication number CN213670928U discloses a sponge iron inner hole cleaning device, which includes multiple brush cleaning assemblies, each of which includes an inner hole brush, which is vertically and coaxially fixed to the lower end of a brush rod, and the upper end of the brush rod is connected to a rotary drive device through a universal joint; the inner hole brush simultaneously performs up and down motion and rotational motion in the inner hole of the sponge iron.

[0007] Although the above device can use a machine to clean the inner hole of sponge iron, in actual use, the sponge iron is stacked on the platform without further stabilization. Since the sponge iron stack is unstable, it is easy to shake during the cleaning process, which makes it impossible for the inner hole brush and the inner hole of the sponge iron to always maintain good coaxiality, thereby reducing the accuracy of cleaning, resulting in incomplete cleaning and affecting the cleaning effect. The unstable stack may be at risk of collapse during the cleaning process. The shaking of the stack will cause the inner hole brush, brush rod, universal drive shaft and other components to bear uneven force, increase the wear of these components, reduce the service life of the equipment, and increase maintenance costs. To this end, we propose a sponge iron inner hole cleaning device to solve the above problems. Utility Model Content

Fixed grooves 205 are provided on both sides of the inner wall of the mounting groove 204, and the fixed grooves 205 on both sides are symmetrically distributed along the axis of the mounting groove 204. The fixed grooves 205 have built-in The rotating roller 206 has two ends that are in contact with the bottom of the inner cavity of the fixed grooves 205 on both sides, and the rotating roller 206 is rotatably connected to the bottom of the inner cavity of the fixed grooves 205. The two ends of the rotating roller 206 are sleeved with torsion springs 207, and the torsion springs 207 at both ends are symmetrically distributed along the axis of the rotating roller 206. The torsion springs 207 at both ends are respectively placed in the fixed grooves 205 on both sides. One end of the torsion spring 207 is fixedly connected to the groove wall of the fixed groove 205, and the other end of the torsion spring 207 is fixedly connected to the surface of the rotating roller 206. The middle of the rotating roller 206 is sleeved with a connecting seat 208 The connecting seat 208 is fixedly connected to the rotating roller 206, and both sides of the connecting seat 208 are slidably connected to the groove wall of the installation groove 204. The end of the connecting seat 208 away from the rotating roller 206 is fixedly connected to a positioning seat 209 for contacting the sponge iron body 3. The end of the positioning seat 209 away from the connecting seat 208 passes through the installation groove 204 and extends to the inner cavity of the positioning cylinder 201. The groove wall on the side of the installation groove 204 away from the rotating roller 206 is provided with an embedded groove 212 for easy entry of the positioning seat 209. The positioning seat 209 slides with the groove wall of the embedded groove 212. Dynamic connection, the positioning seat 209 is provided with an inclined surface 210 on the side away from the sponge iron body 3 to facilitate the sponge iron body 3 to squeeze itself, the sponge iron body 3 is slidably connected to the surface of the inclined surface 210, and a plurality of evenly distributed friction pads 211 are fixedly connected to the surface of the inclined surface 210.

The positioning seat 209 is fixed to the sponge iron body 3 under the elastic force of the coil spring, which is convenient for subsequent inner hole cleaning.

[0030] Working Principle: When using this device, multiple threaded cylinders 101 are evenly distributed on the platform of the cart 1. The bottom outer surfaces of the multiple positioning cylinders 201 of the positioning assembly 2 are provided with external threads 202 that match the threaded cylinders 101. These positioning cylinders 201 are fixed to the platform of the cart 1 through a threaded connection. The tops of the positioning cylinders 201 have an annular opening 203 that allows the sponge iron bodies 3 to enter. During stacking, the sponge iron bodies 3 are pressed against the positioning seat 209. The positioning seat 209 is connected to the rotating roller 206 via the connecting seat 208. The rotating roller 206 has torsion springs 207 sleeved on both ends and is rotatably connected to the bottom of the fixed groove 205. When the sponge iron bodies 3 press against the positioning seat 209, the positioning seat 209 moves into the mounting groove 204, driving the connecting seat 208 to slide along the groove wall. Simultaneously, the rotating roller 206 rotates, causing the torsion spring 207 to deform.

[0031] When the sponge iron body 3 is fully inserted into the positioning cylinder 201, the positioning seat 209, driven by the elastic force of the torsion spring 207, extends out of the mounting slot 204 and contacts and secures the sponge iron body 3. The positioning seat 209 has an inclined surface 210 on the side facing away from the sponge iron body 3. A plurality of evenly distributed friction pads 211 are fixedly attached to the surface of the inclined surface 210.

The inner bore brush is vertically and coaxially fixed to the lower end of the brush rod, the upper end of which is connected to the rotary drive device via a universal drive shaft. When the cart 1 is pushed to the inner bore brush position, the inner bore brush simultaneously moves up and down and rotates within the inner bore of the sponge iron body 3, cleaning the inner bore of the sponge iron body 3.

[0032] Multiple positioning cylinders 201 are fixed to the platform of the cart 1 via threads and are evenly distributed, ensuring the stability of the stacking of the sponge iron bodies 3. The positioning seats 209 within the positioning cylinders 201, driven by the torsion springs 207 and coil springs, accurately contact and secure the sponge iron bodies 3, preventing displacement of the sponge iron bodies 3 during stacking and transportation, ensuring accurate cleaning of the inner bore. The annular opening 203 at the top of the positioning cylinders 201 facilitates the entry of the sponge iron bodies 3, making the stacking process simple and quick. The inclined surface 210 design of the positioning seat 209 enables the sponge iron body 3 to automatically squeeze the positioning seat 209 into the positioning cylinder 201 during stacking, without the need for additional operation, thereby improving work efficiency. The multiple mounting grooves 204 on the inner wall of the positioning cylinder 201 are evenly distributed, and the positioning seat 209 in the mounting groove 204 can be adjusted according to the size and shape of the sponge iron body 3 to adapt to the stacking and inner hole cleaning requirements of sponge iron bodies 3 of different specifications. The inner hole brush moves up and down and rotates simultaneously in the inner hole of the sponge iron body 3, which can comprehensively and thoroughly clean the inner hole of the sponge iron body 3, thereby improving the cleaning effect.
