Technical Field
[0001] This utility model relates to the field of heat preservation furnace technology, and in particular to an ash removal device for the interior of a horizontal heat preservation furnace. Background Technology
[0002] A horizontal holding furnace is an industrial device used to heat and maintain materials at a certain temperature. It is named for its horizontal placement. After long-term use, dust will accumulate on the inner wall of the holding furnace. When dust accumulates on the inner wall of the holding furnace, it will change the heat transfer path and increase heat loss. This will not only increase the energy consumption of the holding furnace, but may also lead to uneven temperature inside the furnace, affecting the stability of the production process and product quality.
[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: dust accumulates on the inner wall of the heat preservation furnace body for a long time, which leads to changes in the heat transfer path, increases heat loss, and thus increases the energy consumption of the heat preservation furnace body; therefore, in order to solve the above problems, an ash removal device for the interior of a horizontal heat preservation furnace is proposed. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where dust accumulates on the inner wall of the insulation furnace for extended periods, altering the heat transfer path, increasing heat loss, and consequently increasing the energy consumption of the insulation furnace. This invention proposes an ash removal device for the interior of a horizontal insulation furnace.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an ash removal device for the interior of a horizontal heat preservation furnace, comprising a heat preservation furnace body, a base mounted on the surface of the heat preservation furnace body, an ash removal device provided on the inner wall of the heat preservation furnace body, the ash removal device comprising an ash removal plate, the ash removal plate being slidably connected to the inner wall of the heat preservation furnace body, a cross fixedly connected to the surface of the ash removal plate, a threaded rod inserted into the internal thread of the cross, four connecting rods fixedly connected to the surface of the base, a servo motor fixedly connected to one end of the four connecting rods away from the base, and the output end of the servo motor being fixedly connected to the threaded rod.
[0006] The effect achieved by the above-mentioned components is as follows: by setting up a dust removal device, the dust inside the heat preservation furnace body can be cleaned, avoiding the accumulation of dust on the inner wall of the heat preservation furnace body for a long time, which would change the heat transfer path, increase heat loss, and thus increase the energy consumption of the heat preservation furnace body, thereby improving the practicality of the equipment.
[0007] Preferably, the surface of the dust removal plate is fixedly connected to two fixing plates, the size of which is adapted to the size of the dust removal plate.
[0008] The aforementioned components achieve the following effect: the fixing plate can move the dust along with it, bringing the dust together so that staff can clean the dust in a unified manner.
[0009] Preferably, one end of the threaded rod has a groove, and a blocking block is fixedly connected to the surface of the groove.
[0010] The effect achieved by the above components is to fix the cross in place, thus preventing the cross from slipping off the arc surface of the threaded rod when the threaded rod moves without proper obstruction.
[0011] Preferably, a sliding block is slidably connected to the arc surface of the threaded rod, and a spring is sleeved on the arc surface of the threaded rod, with the two ends of the spring being fixedly connected to a blocking block and a sliding block, respectively.
[0012] The effect achieved by the above components is that the spring can buffer the impact, preventing the cross from directly contacting the surface of the blocking block. If the cross continues to move, it will damage the threads on the arc surface of the threaded rod, causing the threaded rod to malfunction.
[0013] Preferably, the inner wall of the heat preservation furnace body is provided with a collection device, the collection device includes a storage compartment, the storage compartment is fixedly connected to the inner wall of the heat preservation furnace body, the surface of the storage compartment is provided with a plurality of drop holes, a collection box is slidably connected to the surface of the storage compartment, and a handle is fixedly connected to the surface of the collection box.
[0014] The effect achieved by the above-mentioned components is as follows: by setting up a collection device, the dust on the inner wall of the heat preservation furnace body can be collected, avoiding the situation where the dust that the staff cleans has no suitable place to be placed, which would force the staff to open the heat preservation furnace body to deal with the dust. This reduces the number of times the staff need to open the heat preservation furnace body to clean the dust and improves the practicality of the equipment.
[0015] Preferably, two round rods are fixedly connected to the surface of the storage compartment, a limiting plate is fixedly connected to the end of the round rods away from the storage compartment, and two limiting blocks are fixedly connected to the surface of the collection box.
[0016] The effect achieved by the above components is to fix the collection box in place, preventing the collection box from sliding on the surface of the storage compartment and causing dust to not fall completely into the collection box.
[0017] Preferably, a torsion spring is fitted onto the arc surface of the round rod, and the two ends of the torsion spring are fixedly connected to the limiting plate and the storage compartment, respectively.
[0018] The effect achieved by the above components is that the torsion spring's torque can automatically rotate the limiting plate back to its original position, while also restricting the rotation of the limiting plate and improving the stability of the limiting plate when it is in position.
[0019] In summary, the beneficial effects of this utility model are as follows:
[0020] 1. In this utility model, by setting up a dust removal device, the dust inside the heat preservation furnace body can be cleaned, avoiding the situation where dust accumulates on the inner wall of the heat preservation furnace body for a long time, which would change the heat transfer path, increase heat loss, and thus increase the energy consumption of the heat preservation furnace body, thereby improving the practicality of the equipment.
[0021] 2. In this utility model, by setting up a collection device, the dust on the inner wall of the heat preservation furnace body can be collected, avoiding the situation where the dust cleaned by the staff has no suitable place to be placed, which would force the staff to open the heat preservation furnace body to deal with the dust, causing the staff to frequently open the heat preservation furnace body to clean the dust, thus reducing the number of times the staff need to open the heat preservation furnace body to clean the dust and improving the practicality of the equipment.

[0029] Reference Figure 1As shown, this utility model provides a technical solution: an ash removal device for the interior of a horizontal heat preservation furnace, including a heat preservation furnace body 1, a base 2 installed on the surface of the heat preservation furnace body 1, and an ash removal device 3 provided on the inner wall of the heat preservation furnace body 1. By setting the ash removal device 3, the dust inside the heat preservation furnace body 1 can be cleaned, avoiding the accumulation of dust on the inner wall of the heat preservation furnace body 1 for a long time, which would change the heat transfer path, increase heat loss, and thus increase the energy consumption of the heat preservation furnace body 1, thereby improving the practicality of the equipment. The inner wall of the heat preservation furnace body 1 is provided with a collection device 4, which can collect the dust on the inner wall of the heat preservation furnace body 1, avoiding the situation where the dust cleaned by the staff has no suitable place to be placed, forcing the staff to open the heat preservation furnace body 1 to deal with the dust, and causing the staff to frequently open the heat preservation furnace body 1 to clean the dust, thus reducing the number of times the staff open the heat preservation furnace body 1 to clean the dust, and improving the practicality of the equipment.
[0030] The specific setup and function of the dust removal device 3 and the collection device 4 will be described in detail below.
[0031] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the dust removal device 3 includes a dust removal plate 35, which is slidably connected to the inner wall of the heat preservation furnace body 1. A cross 34 is fixedly connected to the surface of the dust removal plate 35, and a threaded rod 33 is threaded into the cross 34. Four connecting rods 31 are fixedly connected to the surface of the base 2. A servo motor 32 is fixedly connected to the end of the four connecting rods 31 away from the base 2. The output end of the servo motor 32 is fixedly connected to the threaded rod 33. Two fixing plates 36 are fixedly connected to the surface of the dust removal plate 35. The size of the fixing plates 36 is adapted to the size of the dust removal plate 35. When the operator needs to clean the dust on the inner wall of the heat preservation furnace body 1, the servo motor 32 is started. The output end of the machine 32 drives the threaded rod 33 to rotate, the threaded rod 33 drives the cross 34 to move back and forth, the cross 34 drives the cleaning plate 35 to move, until the dust on the inner wall of the heat preservation furnace body 1 is cleaned off. When the cleaning plate 35 moves, it drives the fixing plate 36 to move, and the fixing plate 36 drives the dust to move, thereby collecting the dust together, which facilitates unified cleaning by the staff. The fixing plate 36 achieves the effect of moving the dust together, making it convenient for the staff to clean the dust together. One end of the threaded rod 33 has a groove, and a blocking block 37 is fixedly connected to the surface of the groove of the threaded rod 33. When the staff needs to clean the inner wall of the heat preservation furnace body 1, a blocking block 37 is provided. When dust accumulates, the servo motor 32 is activated. The output of the servo motor 32 drives the threaded rod 33 to rotate. The threaded rod 33 moves the crossbar 34 back and forth, and the crossbar 34 moves the cleaning plate 35. When the surface of the crossbar 34 contacts the blocking block 37, the crossbar 34 stops moving and is fixed. This achieves the effect of fixing the crossbar 34, preventing the crossbar 34 from slipping off the arc surface of the threaded rod 33 due to the lack of suitable obstruction when the threaded rod 33 moves. The arc surface of the threaded rod 33 is slidably connected to a sliding block 38, and a spring 39 is sleeved on the arc surface of the threaded rod 33. The two ends of the spring 39 are respectively connected to the blocking block 37. 7 and sliding block 38 are fixedly connected. When the output end of servo motor 32 drives threaded rod 33 to rotate, threaded rod 33 drives cross 34 to move, cross 34 drives cleaning plate 35 to move, and cleaning plate 35 drives fixed plate 36 to move. When the surface of cross 34 contacts sliding block 38, spring 39 is compressed. At this time, the operator can stop servo motor 32, so that cross 34 stops moving. Spring 39 achieves the buffering effect, avoiding cross 34 from directly contacting the surface of blocking block 37. If cross 34 continues to move, the threads on the arc surface of threaded rod 33 will be damaged, causing threaded rod 33 to be unable to be used normally.
[0032] Reference Figure 5 and Figure 6As shown, specifically, the collection device 4 includes a storage compartment 41, which is fixedly connected to the inner wall of the furnace body 1. Several drop holes are provided on the surface of the storage compartment 41. A collection box 42 is slidably connected to the surface of the storage compartment 41. A handle 43 is fixedly connected to the surface of the collection box 42. Two round rods 44 are fixedly connected to the surface of the storage compartment 41. A limit plate 45 is fixedly connected to one end of each round rod 44 away from the storage compartment 41. Two limit blocks 46 are fixedly connected to the surface of the collection box 42. When the worker uses the dust removal plate 35 to clean the dust from the inner wall of the furnace body 1, the dust falls into the collection box 42. On the surface of the storage compartment 41, the dust removal plate 35 moves the fixing plate 36, which in turn moves the dust. The dust falls through the drop hole in the storage compartment 41 into the collection box 42. When there is a lot of dust in the collection box 42, the staff can clean it. Rotate the limiting plate 45. When the limiting plate 45 is completely disengaged from the surface of the limiting block 46, the limiting plate 45 releases its restriction on the collection box 42. Pull the handle 43. The handle 43 moves the collection box 42. When the collection box 42 is completely disengaged from the surface of the storage compartment 41, the staff can clean the dust inside the collection box 42. After cleaning, the collection box 42 is moved back to its original position. The limiting plate 45 is rotated, causing the round rod 44 to rotate. When the limiting plate 45 rotates to the surface of the limiting block 46, it fixes the collection box 42, thus securing it and preventing it from sliding on the surface of the storage compartment 41, which would prevent dust from falling completely into the collection box 42. A torsion spring 47 is fitted onto the arc surface of the round rod 44. Both ends of the torsion spring 47 are fixedly connected to the limiting plate 45 and the storage compartment 41, respectively. When the staff needs to remove the collection box 42, the rod is rotated... When the limiting plate 45 is completely detached from the surface of the limiting block 46, the limiting plate 45 releases its restriction on the collection box 42, allowing the worker to remove the collection box 42. After the worker moves the collection box 42 back to its original position, the limiting plate 45 is released, and the torque of the torsion spring 47 drives the limiting plate 45 to rotate until the limiting plate 45 rotates to the surface of the limiting block 46. At this point, the limiting plate 45 fixes the limiting block 46, and the torque of the torsion spring 47 achieves the effect of automatically rotating the limiting plate 45 back to its original position. At the same time, it can limit the rotation of the limiting plate 45, improving the stability of the limiting plate 45 when it is in a limiting position.
[0033] Working principle: When the staff needs to clean the dust on the inner wall of the heat preservation furnace body 1, the servo motor 32 is started. The output end of the servo motor 32 drives the threaded rod 33 to rotate, the threaded rod 33 drives the cross 34 to move, and the cross 34 drives the cleaning plate 35 to move until the cleaning plate 35 cleans the dust off the inner wall of the heat preservation furnace body 1. When the cleaning plate 35 moves, it drives the fixing plate 36 to move, and the fixing plate 36 drives the dust to move. At this time, the fixing plate 36 collects the dust together, making it convenient for the staff to clean it uniformly. When the surface of the cross 34 contacts the sliding block 38, the spring 39 is compressed. At this time, the staff can stop the servo motor 32, so that the cross 34 stops moving. This achieves the effect of cleaning the dust inside the heat preservation furnace body 1, avoiding the situation where dust accumulates on the inner wall of the heat preservation furnace body 1 for a long time, which would change the heat transfer path, increase heat loss, and thus increase the energy consumption of the heat preservation furnace body 1.
[0034] When the worker uses the cleaning plate 35 to clean the dust on the inner wall of the insulation furnace body 1, the dust falls onto the surface of the collection bin 41. The cleaning plate 35 moves the fixing plate 36, which in turn moves the dust. The dust falls through the drop hole in the collection bin 41 into the collection box 42. When there is a lot of dust in the collection box 42, the worker can clean it. The worker can then rotate the limiting plate 45. When the limiting plate 45 is completely disengaged from the surface of the limiting block 46, the limiting plate 45 releases its restriction on the collection box 42. Pulling the handle 43 moves the collection box 42. When the collection box 42 is completely disengaged from the surface of the collection bin 41, the worker can then... The staff can clean the dust in the collection box 42. After cleaning, the collection box 42 is moved back to its original position, the limiting plate 45 is released, and the torque of the torsion spring 47 drives the limiting plate 45 to rotate until the limiting plate 45 rotates to the surface of the limiting block 46. At this time, the limiting plate 45 fixes the limiting block 46, thus achieving the effect of collecting the dust on the inner wall of the heat preservation furnace body 1. This avoids the situation where the dust cleaned by the staff has no suitable place to be placed, which would force the staff to open the heat preservation furnace body 1 to deal with the dust, causing the staff to frequently open the heat preservation furnace body 1. This reduces the number of times the staff need to open the heat preservation furnace body 1 to clean the dust.
