[0002] In existing technology, the saggers containing materials are fed into the kiln and fired for a certain period of time before being removed. During the firing process, dust may be emitted to varying degrees and fall to the bottom. Because the dust hardens when mixed with grease and impurities, it is necessary to promptly remove the accumulated ash inside the kiln, especially the ash that falls to the bottom of the kiln. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a ash removal component, which aims to solve the problem that the existing experimental kilns are all integrated structures, which have low flexibility and cannot quickly adjust parameter requirements and switch test processes.

[0004] This utility model provides a dust removal component for cleaning the accumulated ash at the bottom of a kiln. It includes a horizontal rod and a vertical rod. One end of the vertical rod extends movably into the kiln and connects to the horizontal rod, while the other end extends out of the kiln. The horizontal rod abuts against the bottom of the kiln. The end of the vertical rod extending out of the kiln serves as a power input end and is used to drive the vertical rod to perform linear reciprocating motion so that the horizontal rod scrapes away the accumulated ash at the bottom of the kiln.

[0005] In some embodiments of this invention, the transverse bar and the longitudinal bar are detachably connected.

[0006] In some embodiments of this utility model, a connecting cylinder is sleeved at one end of the longitudinal rod extending into the kiln, and the transverse rod has an installation hole through which the connecting cylinder can pass. Both the connecting cylinder and the longitudinal rod have a plurality of first insertion holes, and a first insertion member is detachably inserted into the first insertion hole. Two adjacent first insertion members are used to fix the transverse rod to the longitudinal rod.

[0007] In some embodiments of this utility model, a handle is detachably connected to one end of the longitudinal rod extending outside the kiln. The handle is used to grip and drive the longitudinal rod to perform linear reciprocating motion.

[0008] In some embodiments of this utility model, both the handle and the longitudinal rod are provided with a second insertion hole, and a second insertion member is detachably inserted into the second insertion hole. The second insertion member is used to fix the handle to the longitudinal rod.

[0009] In some embodiments of this utility model, the side of the transverse rod that abuts against the bottom of the kiln is a first side, and the side of the transverse rod that is away from the bottom of the kiln is a second side. The area of ​​the first side is smaller than the area of ​​the second side, and the hardness of the first side is lower than the hardness of the bottom of the kiln.

[0010] This utility model also provides a kiln, including the ash removal component as described above, wherein a guide tube is provided on the side of the kiln, and the guide tube allows the longitudinal rod to be inserted into the kiln.

[0011] In some embodiments of this utility model, a graphite sleeve is provided inside the guide tube, and the inner circumferential surface of the graphite sleeve abuts against the outer circumferential surface of the longitudinal rod.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a dust removal component for cleaning the accumulated ash at the bottom of a kiln. It includes a horizontal rod 1 and a vertical rod 2. One end of the vertical rod 2 extends movably into the kiln and connects to the horizontal rod 1, while the other end extends out of the kiln. The horizontal rod 1 abuts against the bottom of the kiln. The end of the vertical rod 2 extending out of the kiln serves as a power input end and is used to drive the vertical rod 2 to perform linear reciprocating motion so that the horizontal rod 1 scrapes away the accumulated ash at the bottom of the kiln.

[0023] Since the power output end of the longitudinal rod 2 of this utility model extends to the outside of the kiln as the power output end, there is no need to shut down the kiln during the cleaning of accumulated ash, thus ensuring the normal production of the kiln.

[0024] In this application, the power input end of the longitudinal rod 2 can be driven manually or automatically. If driven manually, simply holding the longitudinal rod 2 is sufficient to pull it back and forth. If driven automatically, a drive motor can be connected to the power input end of the longitudinal rod 2, with the rod body threadedly connected to the kiln. The drive motor drives the longitudinal rod 2 to rotate, converting the rotational motion into linear reciprocating motion that drives the transverse rod 1.

[0025] In some embodiments of this invention, the transverse rod 1 and the longitudinal rod 2 are detachably connected. This facilitates the assembly of the transverse rod 1 and the longitudinal rod 2, or their replacement when one component is damaged. Furthermore, if the connection between the transverse rod 1 and the longitudinal rod 2 adopts an integral rigid structure, thermal deformation is likely to occur under the high-temperature environment of the kiln.

[0026] In some embodiments of this utility model, a connecting cylinder 3 is sleeved at one end of the longitudinal rod 2 extending into the kiln. The transverse rod 1 has an installation hole through which the connecting cylinder 3 passes. Both the connecting cylinder 3 and the longitudinal rod 2 have several first insertion holes. A first insertion member 32 is detachably inserted into each of the first insertion holes. Two adjacent first insertion members 32 are used to fix the transverse rod 1 to the longitudinal rod 2. It is understood that during installation, the end of the longitudinal rod 2 is inserted into the connecting cylinder 3, so that the first insertion holes on the connecting cylinder 3 and the longitudinal rod 2 are aligned and connected. Preferably, both the connecting cylinder 3 and the longitudinal rod 2 have two first insertion holes. After insertion, the first insertion member 32 is a screw with a nut, which is inserted into the first insertion holes on the connecting cylinder 3 and the longitudinal rod 2. Next, insert the connecting sleeve 3 into the mounting hole until one side of the transverse rod 1 abuts against the already installed nut. Then, insert the threaded rod into the other insertion hole, connecting the nut to the other side of the transverse rod 1 and the subsequently installed nut, thereby confining the transverse rod 1 to the longitudinal rod 2. It is worth noting that the spacing between the two threaded rods precisely matches the dimensions of the transverse rod 1, ensuring the stability of the transverse rod 1 after installation.

[0027] In some embodiments of this invention, a handle 4 is detachably connected to one end of the longitudinal rod 2 extending outside the kiln. The handle 4 is used to grip and drive the longitudinal rod 2 in a linear reciprocating motion. In this embodiment, the handle 4 provides a point of force for driving the longitudinal rod 2, facilitating its movement. The detachable connection of the handle 4 allows it to be removed when cleaning accumulated ash, preventing the handle 4 from being continuously connected to the longitudinal rod 2, which could cause the high temperature inside the kiln to be transferred to the handle 4, affecting the operator's grip.

[0028] In some embodiments of this utility model, both the handle 4 and the longitudinal rod 2 are provided with second insertion holes. A second insertion member 42 is detachably inserted into the second insertion hole, and the second insertion member 42 is used to fix the handle 4 onto the longitudinal rod 2. It can be understood that when the second insertion member 42 is inserted into the second insertion hole, the relative position of the handle 4 and the longitudinal rod 2 can be determined. The second insertion member 42 is also a screw with a nut, which can prevent the screw from sliding out of the second insertion hole. Preferably, the handle 4 allows the longitudinal rod 2 to be inserted, thereby aligning the second insertion holes of both, facilitating screw insertion.

[0029] In some embodiments of this invention, the side of the transverse rod 1 that abuts against the bottom of the kiln is called the first side, and the side of the transverse rod 1 that is away from the bottom of the kiln is called the second side. The area of ​​the first side is smaller than the area of ​​the second side. If the first side of the transverse rod has a large area, it is prone to bending deformation due to uneven resistance, resulting in an unbalanced scraping pressure distribution (e.g., high pressure at the edges and low pressure in the center), leading to missed scraping or excessive wear. In addition, an excessively large area of ​​the first side also increases the resistance during the scraping of kiln ash. Therefore, the resistance experienced by the transverse rod is reduced by reducing the area of ​​the first side. Specifically, an inclination angle of 15°-30° is set on the first side, reducing the actual contact area by 30%-50%.

[0030] In some embodiments of this invention, the hardness of the first surface is lower than the hardness of the bottom of the kiln. Preferably, the first surface can be made of graphite. When the graphite comes into contact with the bottom of the kiln, it preferentially undergoes elastic deformation (deformation amount δ≥0.2mm) under contact pressure, avoiding plastic damage to the bottom of the kiln, and protecting the bottom of the kiln through the flexible contact of the graphite.

[0031] Furthermore, the two ends of the transverse rod 1 abut against the sides of the kiln, effectively preventing ash from leaking from the side gap between the transverse rod 1 and the kiln, thus improving the ash removal effect.

[0032] This utility model also provides a kiln, including the ash-cleaning component as described above. A guide cylinder 5 is provided on the side of the kiln, allowing the longitudinal rod 2 to be inserted into the kiln. In this embodiment, the guide cylinder 5 ensures that the longitudinal rod 2 does not deviate during linear reciprocating motion.

[0033] In some embodiments of this utility model, a graphite sleeve 6 is provided inside the guide cylinder 5, and the inner circumferential surface of the graphite sleeve 6 abuts against the outer circumferential surface of the longitudinal rod 2. In this embodiment, because the graphite sleeve 6 has good high-temperature resistance, it can protect the guide cylinder 5 and its internal structure from direct damage from the high-temperature environment of the kiln, extending the service life of the components. In addition, graphite material has a low coefficient of friction and is wear-resistant, which can reduce the wear of the push rod when it moves inside the guide cylinder 5, maintaining the integrity and smoothness of the inner surface of the guide cylinder 5. Furthermore, the graphite sleeve 6 can provide a certain sealing effect, reducing gas or material leakage, while buffering the contact between the longitudinal rod 2 and the guide cylinder 5, reducing mechanical impact.

[0034] In some embodiments of this utility model, a first flange 51 is provided at one end of the guide cylinder 5 extending outside the kiln. A second flange 52 is detachably connected to the first flange 51. A limiting plate 53 is provided between the first flange 51 and the second flange 52, and the limiting plate 53 is used to restrict the graphite sleeve 6 from dislodging from the guide cylinder 5. In this embodiment, the first flange 51 and the second flange 52 are fixed by the limiting plate 53, thereby fixing the graphite sleeve 6 inside the guide cylinder 5. Even if the longitudinal rod 2 rubs against the graphite sleeve 6, it will not cause the graphite sleeve 6 to shift.

[0035] In some embodiments of this utility model, a plurality of ash collection troughs 7 are formed at the bottom of the kiln. The long side of the ash collection trough 7 extends in the same direction as the longitudinal rod 2, and the wide side extends in the same direction as the transverse rod 1. The bottom of the ash collection trough 7 is connected to an ash collection port 71, which is located at the end of the long side of the ash collection trough 7. The ash collection port 71 is used to suck up the ash scraped off by the transverse rod 1. In this example, the dust and waste collected by the ash collection trough 7 can be cleaned regularly by the ash cleaning component, thereby reducing the dust and residue inside the kiln and maintaining the normal operation and good working efficiency of the kiln. Preferably, a plurality of ash collection ports 71 are provided, and the plurality of ash collection ports 71 are evenly spaced along the wide side of the ash collection trough 7. An inverted triangular oblique flow zone is provided inside the ash collection port 71, and the bottom is connected to a main pipe 73 through a branch pipe 72, and then the ash is sucked away by the negative pressure of the fan.

[0036] In some embodiments of this utility model, a guide plate 8 is provided between two adjacent ash collection troughs 7. The guide plate 8 has symmetrically arranged guide slopes 81, which are used to guide the falling dust into the ash collection trough 7. If there is no guide plate 8 between two adjacent ash collection troughs 7, dust and waste may accumulate excessively in a certain area, causing dust and waste to be unable to be discharged in time, thereby affecting the normal operation of the kiln. The design of the guide plate 8 can effectively prevent the concentrated accumulation of dust and waste, ensuring timely discharge of waste. The guide slopes 81 can ensure that dust and waste can fall into the ash collection trough 7 along the guide slopes 81, avoiding accumulation on the guide plate 8.
