Description

Technical Field

[0001] This utility model relates to the technical field of sodium silicate production equipment, specifically to a solid removal device for the inner wall of a kiln. Background Technology

[0002] Sodium silicate, commonly known as sodium silicate, is an important chemical product used in the manufacture of laundry detergent, washing liquid, paper, and various daily necessities. Industrially, it is usually produced by a dry process. Quartz sand and soda ash are mixed in a certain proportion and heated to about 1400°C in a reverberatory furnace to produce molten sodium silicate. The molten sodium silicate is then quenched in water. Some of the molten liquid is blocked and remains in the corners inside the furnace. It does not flow out of the furnace in time and, after being left to cool, becomes solid and sticks to the bottom edges and corners. It is difficult to remove manually and affects the next reaction. Utility Model Content

[0003] The purpose of this invention is to provide a solid removal device for the inner wall of a kiln, which solves the problem that some molten liquid is blocked and remains in the kiln, and becomes solid and sticks to the bottom after being left to cool.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A solid removal device for the inner wall of a kiln includes a bucket and a placement block arranged sequentially from front to back; the front side of the bucket has an inclined surface that gradually rises from front to back; the front side of the placement block has a recessed movable groove, in which an elliptical disc-shaped rotating abutment driven by a drive motor is horizontally installed, and the edge of the rotating abutment is in contact with the rear side of the bucket; the rear side of the bucket is horizontally connected to the movable groove via a spring rod.

[0006] A further technical solution is that a push-pull column is horizontally arranged behind the placement block to move it, and the rear side of the placement block is fixedly connected to the front end of the push-pull column through a fixing hole; a sleeve for fixing is sleeved around the push-pull column; a retractable top contact rod is arranged above the sleeve; a receiving plate is arranged below the sleeve, and a first spring is arranged at each of the four corners of the receiving plate.

[0007] A further technical solution is that the upper side of the push-pull column is provided with several locking teeth at intervals. The front end of the locking teeth is an inclined surface that slopes upward from front to back, and the rear end is a vertical surface. The locking teeth are arranged along the length of the push-pull column. The inner wall of the sleeve is provided with a placement groove corresponding to the locking teeth. A check pawl with a pointed front end is provided in the placement groove and rotates up and down. The pointed front end of the check pawl faces the back of the locking teeth. The rear end of the check pawl is rotatably connected to the inner walls of the left and right ends of the placement groove through a rotating column.

[0008] A further technical solution is that the sleeve has a movable hole horizontally penetrating the inner wall of the rear end of the placement groove; a retaining post is movably installed in the movable hole, and the front end of the retaining post is inserted into the placement groove through the movable hole.

[0009] A further technical solution is that the top contact rod includes a movable rod and a fixed rod; a sleeve is horizontally fixed at the bottom of the movable rod; a pin is movably installed at one open end of the sleeve; a first pin hole is provided through the outer wall of the movable rod corresponding to the pin; several second pin holes are arranged along the length of the fixed rod, penetrating inside and outside; a second spring is movably installed at one end of the pin inside the sleeve; the other end of the pin passes through the first pin hole and the second pin hole in sequence.

[0011] A further technical solution is to provide a second rotating column at the bottom of the support rod, with fixed plates rotatably mounted on both the left and right sides of the second rotating column, and the bottom of the fixed plates being fixedly connected to the sleeve.

[0012] A further technical solution is to have a friction wheel rotatably mounted on the top of the connecting block.

[0013] A further technical solution is to fix a baffle at the rear end of the push-pull column, and to have a handle on the side of the baffle away from the push-pull column.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (i) The bucket moves forward inside the kiln. The rotating abutment, which is shaped like an elliptical disc, is controlled by the drive motor to rotate. During the process, the circumferential side of the rotating abutment always abuts against the rear end of the bucket. Combined with the spring pull rod, the forward-moving bucket is pulled to the rear end, thereby completing the back-and-forth vibration of the bucket. This allows the bucket to repeatedly impact the deposits on the inner wall of the kiln, thereby scooping up the deposits and achieving the effect of cleaning the inner wall.

Detailed Implementation

[0020] 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.

[0021] Example 1:

[0022] A solid removal device for the inner wall of a kiln includes a bucket 1 and a placement block 2 arranged sequentially from front to back. The front side of the bucket 1 has an inclined surface that gradually rises from front to back. The front side of the placement block 2 has a recessed movable groove 3. A rotating abutment 12 in the shape of an elliptical disc, driven by a drive motor 4, is horizontally installed in the movable groove 3. The edge of the rotating abutment 12 is in contact with the rear side of the bucket 1. The rear side of the bucket 1 is horizontally connected to the movable groove 3 via a spring rod 6. When the bucket 1 moves forward inside the kiln, the rotating abutment 12 in the shape of an elliptical disc is rotated by the drive motor 4. During the process, the circumferential side of the rotating abutment 12 is always in contact with the rear side of the bucket 1. Combined with the spring rod 6, the forward-moving bucket 1 is pulled to the rear, thereby completing the back-and-forth vibration of the bucket 1. This allows the bucket 1 to repeatedly impact the deposits on the inner wall of the kiln, thereby scooping up the deposits and achieving the effect of removing the inner wall.

[0023] Example 2:

[0024] A push-pull column 7 is horizontally positioned behind the placement block 2, allowing it to move. The rear side of the placement block 2 is fixedly connected to the front end of the push-pull column 7 via a fixing hole 5. A sleeve 9 for fixing is fitted around the push-pull column 7. A retractable top contact rod 8 is positioned above the sleeve 9. A receiving plate 10 is positioned below the sleeve 9, with a first spring 11 at each of the four corners of the receiving plate 10. The sleeve 9 is pushed upward against the top of the inner wall of the kiln via the top contact rod 8, and the bottom surface is increased by the receiving plate 10 to increase the force-bearing area. The push-pull column 7 is fixed vertically to prevent the application of a reaction force when the bucket 1 is subjected to backward resistance, thereby improving the cleaning efficiency. The first spring 11 is used to extend upward or compress downward to fill gap errors when the top contact rod 8 extends or retracts.

[0025] Example 3:

[0026] The upper side of the push-pull column 7 is provided with several locking teeth 30 at intervals. The front end of each locking tooth 30 is an upward sloping surface from front to back, and the rear end is a vertical surface. The locking teeth 30 are arranged along the length of the push-pull column 7. The inner wall of the sleeve 9 is provided with a placement groove 32 corresponding to the locking teeth 30. A check pawl 31 with a pointed front end is rotatably disposed in the placement groove 32. The pointed front end of the check pawl 31 faces the gap between two adjacent locking teeth 30. The check pawl 31 and the locking teeth 30 combine to form the check valve of the push-pull column 7. The structure prevents the push-pull column 7 from moving backward due to resistance when removing the attached material; the rear end of the check claw 31 is rotatably connected to the inner walls of the left and right ends of the placement groove 32 via the rotating column 35; the check claw 31 and the locking tooth 30 cooperate, with the locking tooth 30 tilted towards the rear end of the push-pull column 7, and the check claw 31 inserted into the gap between two adjacent locking teeth 30, so that when the push-pull column 7 is subjected to backward resistance, the check claw 31 abuts against the back of the tooth of the previous locking tooth 30, preventing the push-pull column 7 from continuing to move backward.

[0027] Example 4:

[0028] A movable hole 34 is horizontally provided through the inner wall of the rear end of the sleeve 9 in the placement groove 32; a locking post 33 is movably disposed in the movable hole 34, and the front end of the locking post 33 is inserted into the placement groove 32 through the movable hole 34; when the front end of the locking post 33 is inserted into the placement groove 32, the originally inclined anti-return claw 31 is supported by the locking post 33 and pulled out from between the two locking teeth 30, and then rotates upward with the rear rotating post 35 as the fulcrum and enters the placement groove 32 to become horizontal, thereby canceling the obstruction of the anti-return claw 31 to the push-pull post 7 to move backward, so that the push-pull post 7 can be pulled backward towards the rear end of the sleeve 9 and return to the initial state; when performing the next shoveling operation, pull back the locking post 33, release the anti-return claw 31 to lock the locking teeth 30, and continue to perform the anti-return function of the push-pull post 7.

[0029] Example 5:

[0030] The top contact rod 8 includes a movable rod 13 and a fixed rod 14. A sleeve 15 is horizontally fixed at the bottom of the movable rod 13. A pin 16 is movably provided at one open end of the sleeve 15. A first pin hole 17 is provided through the outer wall of the movable rod 13 corresponding to the pin 16. Several second pin holes 18 are arranged along the length of the fixed rod 14, penetrating inside and outside. A second spring 26 is movably provided at one end of the pin 16 inside the sleeve 15. The other end of the pin 16 passes through the first pin hole 17 and the second pin hole 18 in sequence. The movable rod 13 and the fixed rod 14 are used to adjust the length of the top contact rod 8 by extension and retraction, and the length is fixed by the pin 16 to fix the movement direction of the bucket 1 within a certain range. The multiple second pin holes 18 on the fixed rod 14 are connected vertically to form a serrated strip hole on the side edge, so that the top contact rod 8 can be finely adjusted in length.

[0031] Example 6:

[0032] A support rod 19 that gradually slopes downwards from front to back is provided on the rear side of the top contact rod 8; a placement block 22 is provided at the top of the top contact rod 8, and a rotation notch 27 is provided in the placement block 22 corresponding to the support rod 19; a first rotating column 20 is horizontally fixed on the left and right inner walls of the rotation notch 27; the top of the support rod 19 is rotatably connected to the first rotating column 20 through a rotation hole 29; the support rod 1, sleeve 9 and top contact rod 8 form a relatively stable triangular structure.

[0033] Example 7:

[0034] A second rotating column 21 is provided at the bottom of the support rod 19. Fixing plates 28 are rotatably provided on both the left and right sides of the second rotating column 21. The bottom end of the fixing plate 28 is fixedly connected to the sleeve 9. The second rotating column 21 serves as the rotation fulcrum of the support rod 19. The angle between the support rod 19 and the sleeve 9 is adjusted according to the height of the top contact rod 8 to ensure that the support rod 19 always provides forward support to the top contact rod 8.

[0035] Example 8:

[0036] The top of the placement block 22 is equipped with a friction wheel 23; the friction wheel 23 uses a rubber wheel with a large inner ring friction, which can deform to adapt to pits of various angles when the top contact rod 8 abuts against the top of the inner wall, and the large friction of the inner ring provides resistance in the front and rear horizontal direction, ensuring that the bucket 1 impacts the attached object each time.

[0037] Example 9:

[0038] A baffle 24 is fixedly installed at the rear end of the push-pull column 7. A handle 25 is provided on the side of the baffle 24 away from the push-pull column 7. The baffle 24 and the handle 25 are used to prevent the operator from touching the inner wall of the kiln and getting burned when pushing the device. At the same time, when the push-pull column 7 is pushed forward to the baffle 24 and abuts the rear end of the sleeve 9, the front side of the baffle 24 pushes the locking column 33 to lock the check claw 31, automatically stopping the check structure from blocking the push-pull column 7, so that the push-pull column 7 can be pulled back to the rear end of the sleeve 9 and return to the initial state.

[0039] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
