Description

Technical Field

[0001] The utility model relates to the technical field of high-temperature sintering furnaces, in particular to a protective component of a high-temperature sintering furnace for ceramic production. Background Art

[0002] Ceramics are products made primarily from natural silicates such as clay. Ceramics offer numerous advantages, including excellent insulation, corrosion resistance, high temperature resistance, high hardness, low density, and radiation resistance. They are widely used in various industries and in household items. Clay is typically used to form a base body, which is then fired and shaped in a high-temperature sintering furnace. After firing, the doors of traditional high-temperature sintering furnaces require the operator to be physically close to open them, which can easily cause burns to the user's skin. To address this issue, existing high-temperature sintering furnaces for ceramic production feature door locks located on the side adjacent to the furnace opening, which are automatically opened by a spring. However, since these doors are typically hinged or sliding, fully opening them with a spring alone is difficult, requiring manual assistance from a close distance. This poses a risk of burns to the operator's skin, resulting in relatively poor safety measures.

[0003] Existing patent application number: 202222021747.8 discloses a high-temperature sintering furnace for ceramic production. This device arranges a locking hook on the side adjacent to the high-temperature sintering furnace opening, so that the user can easily open the locking hook from the side. The furnace door automatically opens under the tension of a spring, preventing the high-temperature air waves in the furnace from impacting the user's skin and improving the protection effect for the user. In the above-mentioned prior art, the above-mentioned technical problems still exist when the furnace door is opened after the ceramic firing is completed. Utility Model Content

[0004] The purpose of the present utility model is to provide a protective component for a high-temperature sintering furnace for ceramic production, so as to solve the problem raised in the above-mentioned background technology that the spring force is difficult to fully open the furnace door, and manual assistance is still required to open the furnace door at close range. There is still a possibility that workers will be burned by high-temperature air waves, and the safety protection effect is relatively poor.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The utility model provides a protective assembly for a high-temperature sintering furnace for ceramic production, comprising a door lock sleeve fixed to the furnace body and a door lock member provided on the furnace door for locking the furnace door. The protective assembly for the high-temperature sintering furnace for ceramic production also includes:

[0007] An auxiliary part installed on the furnace door to safely assist the furnace door in opening.

[0008] A linkage member is provided between the auxiliary member and the door locking member for linking the two.

[0009] The auxiliary parts include:

[0010] Relative to the limiting sleeve frame arranged on the furnace door, the two limiting sleeve frames are surrounded to form an active cavity.

[0011] A round-head rod is slidably sleeved in the movable cavity.

[0012] Relative to the limiting sleeve arranged on the furnace door, the two limiting sleeves are surrounded to form a limiting plug-in area.

[0013] A cross bar is slidably sleeved on the position-limiting plug-in area.

[0014] A U-shaped connecting rod is fixed between the round head rod and the cross rod.

[0015] Furthermore, the depth of the movable cavity is greater than the diameter of the round-headed rod, and the depth of the movable cavity is less than the length of the round-headed rod.

[0016] Furthermore, the limiting sleeve is located above the limiting sleeve frame, and the limiting sleeve and the limiting sleeve frame are parallel.

[0017] Furthermore, the door locking member includes:

[0018] A sleeve fixed to the edge of the furnace door.

[0019] A latch is slidably sleeved with a guide groove arranged in the sleeve.

[0020] Furthermore, the linkage comprises:

[0021] Support block fixed to the furnace door.

[0022] A guide rod is threadedly mounted on the thread groove on the support block, one end of the guide rod is plugged into the receiving hole on the latch, and a rope hole is provided on the end surface of the guide rod.

[0023] A compression spring is slidably sleeved on the outside of the guide rod, and the compression spring is located between the support block and the latch.

[0024] The guide rope rings are fixed relatively to each other on the furnace door.

[0025] A steel wire rope is fixed on the cross bar, one end of the steel wire rope passes through the two guide rope rings and the interior of the rope hole in sequence, and one end of the steel wire rope extends to the receiving hole and is fixed on the inner wall of the receiving hole.

[0026] Furthermore, the support block is located between the compression spring and one of the guide rope rings, and the other guide rope ring is located obliquely above the limiting sleeve.

[0027] Compared with the existing technology, one or more of the above technical solutions have the following beneficial effects:

[0028] 1. The utility model uses auxiliary parts and linkage parts in conjunction with other structures. The operator can stand in the middle of the back of the furnace door and use the auxiliary parts to open the door lock. Then, the operator can deflect downward along the vertical direction of the furnace door surface and then push the U-shaped connecting rod horizontally to open the furnace door. This ensures that the operator is always in a position relative to the middle of the back of the furnace door. The furnace door shields and protects the operator, preventing the high-temperature air waves in the furnace from burning the operator's skin, thereby improving the safety of the furnace door opening operation.

[0029] 2. The utility model uses auxiliary parts and linkage parts in conjunction with other structures. After the ceramic firing is completed, the user can stand in the middle of the furnace door and push up the U-shaped connecting rod to disengage the cross bar from the limit sleeve, and then deflect it downward in a direction parallel to the furnace door surface. The linkage effect of the linkage part opens the door lock part, preventing the operator from being outside the shielding range of the furnace door when the furnace door is opened and being affected by the high temperature in the furnace, thereby improving the safety of the operator when opening the furnace door.

[0035] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application.

[0036] like Figures 1 to 4As shown, a protective assembly for a high-temperature sintering furnace for ceramic production includes a door lock sleeve 3 fixed to the furnace body and a door lock member 2 provided on the furnace door for locking the furnace door. The protective assembly for a high-temperature sintering furnace for ceramic production also includes:

[0037] An auxiliary component 1 is provided on the furnace door for safely assisting the furnace door in opening.

[0038] A linkage member 4 is provided between the auxiliary member 1 and the door locking member 2 for linking the two.

[0039] Auxiliary parts 1 include:

[0040] Relative to the limiting sleeve 11 provided on the furnace door, the two limiting sleeves 11 enclose and form an active cavity 12 .

[0041] A round rod 13 is slidably sleeved in the movable cavity 12 .

[0042] Relative to the limiting sleeve 14 provided on the furnace door, the two limiting sleeves 14 enclose and form a limiting plug-in area.

[0043] The cross bar 15 is slidably sleeved in the position-limiting plug-in area.

[0044] A U-shaped connecting rod 16 is fixed between the round head rod 13 and the cross rod 15.

[0045] After the ceramic firing is completed, the operator stands in the middle of the furnace door outside and first holds the U-shaped connecting rod 16 and pushes it vertically upwards to disengage the cross bar 15 from the limited plug-in area, and then deflects the U-shaped connecting rod 16 toward the connection between the furnace door and the furnace body by a certain angle, so that it pulls the linkage 4, which is convenient for the operator to open the door locking part 2 through the linkage 4 and release the furnace door locking state, and then deflects the U-shaped connecting rod 16 downward until the vertical section at one end of the U-shaped connecting rod 16 hits the furnace door. At this time, the middle section of the U-shaped connecting rod 16 is perpendicular to the furnace door surface, and the operator pushes the U-shaped connecting rod 16 horizontally in the furnace door opening direction to open the furnace door. During the process of fully opening the furnace door, the operator is always in the middle of the outside of the furnace door, and the high-temperature air waves emerging from the furnace will be blocked by the furnace door to avoid the high-temperature air waves from burning the operator's skin, thereby improving the safety of opening the furnace door.

[0046] In this embodiment, the depth of the movable cavity 12 is greater than the diameter of the round-headed rod 13, and the depth of the movable cavity 12 is less than the length of the round-headed rod 13. This design facilitates the up and down translation of the round-headed rod 13, and pushes the cross bar 15 up and down through the U-shaped connecting rod 16, which facilitates the cross bar 15 to be disengaged from or inserted into the limit plug-in area. When opening the locking door component 2, it is necessary to disengage the cross bar 15 from the limit plug-in area, and make the U-shaped connecting rod 16 deflect downward in the vertical direction with its connection with the round-headed rod 13 as the deflection center, and drive the round-headed rod 13 to deflect synchronously in the movable cavity 12, and make the deflection angle of the round-headed rod 13 less than 45°. In this way, it can drive the linkage component 4, and open the locking door component 2 through its linkage to release the locked state of the furnace door, and prevent the round-headed rod 13 from being disengaged from the movable cavity 12, thereby affecting the opening of the furnace door.

[0047] In this embodiment, the limiting sleeve 14 is located above the limiting sleeve frame 11, and the limiting sleeve 14 is parallel to the limiting sleeve frame 11. Such a design allows the U-shaped connecting rod 16 to be vertically fixed on the furnace door when it is not in use, thereby reducing the horizontal space occupancy of the U-shaped connecting rod 16 and facilitating the operation of opening the door lock 2 and opening the furnace door.

[0048] In this embodiment, the door lock component 2 includes:

[0049] The sleeve 21 is fixed to the edge of the furnace door.

[0050] The latch 23 is slidably connected to the guide groove 22 provided in the sleeve 21. By sliding the latch 23 horizontally in the guide groove 22, the latch 23 can be controlled to be inserted into or disengaged from the lock door sleeve 3, thereby controlling the locking or opening of the furnace door. In combination with the use of the linkage part 4 and the auxiliary part 1, the lock door part 2 can be controlled from a long distance, thereby improving the safety of the furnace door opening operation.

[0051] In this embodiment, the linkage member 4 includes:

[0052] A support block 41 is fixed to the furnace door.

[0053] A guide rod 43 is threadedly mounted on the thread groove 42 provided on the support block 41 , and one end of the guide rod 43 is plugged into the receiving hole 44 provided on the latch 23 . A rope hole 46 is formed on the end surface of the guide rod 43 .

[0054] The compression spring 45 is slidably mounted on the outside of the guide rod 43 and is located between the support block 41 and the latch 23 .

[0055] The guide rope ring 47 is fixed relatively to the furnace door up and down.

[0056] A steel wire rope 48 is fixed to the crossbar 15 , one end of which passes through the two guide rope rings 47 and the interior of the rope hole 46 in sequence, and one end of which extends to the receiving hole 44 and is fixed to the inner wall of the receiving hole 44 .

[0057] When the U-shaped connecting rod 16 is vertically deflected, the free end of the U-shaped connecting rod 16 drives the cross bar 15 to deflect downward and simultaneously pulls the wire rope 48. The wire rope 48 drives the latch 23 to move closer to the support block 41, so that the end of the latch 23 away from the compression spring 45 is disengaged from the lock door sleeve 3. During this process, the latch 23 moves axially along the guide rod 43 and compresses the compression spring 45. The guide rod 43 guides the latch 23 to avoid excessive bending of the compression spring 45, which affects the subsequent resetting action of the latch 23.

[0058] In this embodiment, the support block 41 is located between the compression spring 45 and one of the guide rope rings 47, and the other guide rope ring 47 is located diagonally above the limit sleeve 14. This design allows the wire rope 48 to be arranged in an S shape on the vertical plane, so that when the wire rope 48 is pulled, a smooth pulling effect can be maintained.

[0059] The above description is merely a preferred embodiment of the present invention. Any portion not described in the present invention can be implemented by adopting or drawing upon existing technologies. Of course, the above description is not intended to limit the present invention, nor is the present invention limited to the above examples. Any changes, modifications, additions, or substitutions made by those skilled in the art within the spirit and scope of the present invention shall also fall within the scope of protection of the present invention.
