Description

Technical Field

[0001] The invention belongs to the technical field of ceramic body processing equipment, and in particular relates to a ceramic flat membrane body rapid kiln loading device. Background Art

[0002] The operation of loading ceramic greenware into the kiln before firing is called kiln loading. Obviously, the kiln loading process is directly related to the kiln form and the shape and size of the product. Traditional intermittent kilns such as downdraft kilns and large-section tunnel kilns have large temperature differences in the kiln. Therefore, the product loading operation must be carefully arranged to reduce the impact of temperature differences on products in different parts. For example, products of different sizes and shapes can be mixed and sometimes different products can be fired in different parts of the kiln using the temperature difference in the kiln to achieve the desired results.

[0003] With the elimination of traditional kilns, the application of new kilns and the mass production of single-variety products, kiln loading operations have become increasingly standardized and automated. For example, the roller kiln for firing wide-section rapid wall and floor tiles has completed all automatic blank feeding and arrangement. In addition to considering the horizontal space utilization in the kiln and the longitudinal spacing of the brick rows, there is no need to specifically consider the "kiln loading" problem, and there is no special kiln loading process. However, for large, special-shaped, and small-batch products, loading and firing in modern intermittent kilns (such as loading and firing large electric porcelain in shuttle kilns and hood kilns), this issue still needs to be carefully considered.

[0004] However, when the ceramic flat membrane blank is loaded into the kiln for firing, the boron plates and columns on the kiln car need to be repeatedly dismantled and rebuilt each time after loading and unloading the kiln, which is extremely time-consuming and increases a lot of labor costs. Summary of the invention

[0005] The present invention provides a ceramic flat membrane blank rapid kiln loading device, aiming to solve the problem in the background technology that when the ceramic flat membrane blank is loaded into the kiln for firing, the boron plates and columns on the kiln car need to be repeatedly dismantled and rebuilt each time after loading and unloading the kiln, which is extremely time-consuming and increases a lot of labor costs.

[0006] The present invention is implemented as follows: a ceramic flat membrane blank rapid kiln loading device comprises two oppositely arranged support plates and a plurality of boron plate material stacks evenly arranged between the inner side walls of the two support plates at equal intervals, a connecting plate is arranged between the bottoms of the two support plates, and a storage space for accommodating the ceramic flat membrane blank is formed between each two adjacent boron plate material stacks, and a drawer for stacking a plurality of ceramic flat membrane blanks is slidably arranged in each storage space;

[0007] The boron plate stack is formed by splicing two boron plates and then covering them with at least one mullite hollow plate.

[0008] Preferably, the gap between the two boron plates and the mullite hollow plate forms a filling layer, and the filling layer is filled with alumina powder or corundum sand.

[0009] Preferably, the upper surface and the lower surface of the two boron plates spliced ​​together are both covered with the mullite hollow plate.

[0010] Preferably, the connecting plate is in a concave shape, and the two supporting plates are clamped in the notch of the connecting plate and respectively fit with the two side walls of the notch of the connecting plate.

[0011] Preferably, a first shock-absorbing mechanism is provided at the bottom of the connecting plate, and the first shock-absorbing mechanism includes a bottom plate in contact with the bottom surface of the connecting plate, and side plates are fixedly connected to the opposite sides of the upper surface of the bottom plate, and a plurality of first elastic members are evenly fixed on the inner side wall of each side plate at equal intervals, and the ends of the plurality of first elastic members on each side plate are fixedly connected to a pressure plate, and the two pressure plates are respectively crimped with the two side walls of the connecting plate.

[0012] Preferably, a second shock absorbing mechanism is provided on the lower surface of the base plate, and the second shock absorbing mechanism includes a base located below the base plate and arranged at a distance therefrom, and four universal wheels arranged in a matrix are installed on the lower surface of the base, and a plurality of telescopic devices are evenly and evenly fixedly connected between the base and the base plate at equal intervals, and a second elastic member is sleeved on the outer side of each of the telescopic devices, one end of each of the second elastic members is fixedly connected to the lower surface of the base plate, and the other end of each of the second elastic members is fixedly connected to the upper surface of the base.

[0015] Preferably, the drawer is made of stainless steel.

[0016] Preferably, the front end surface of the drawer is provided with a handle.

[0017] Compared with the prior art, the beneficial effect of the present invention is that the boron plate stack can achieve the ceramic flat membrane blank during the firing process without slight deformation or displacement of the boron plate during the high temperature process, thus avoiding the occurrence of firing quality problems such as deformation and cracking of the blank.

Whether the boron plate stack needs to be dismantled and rebuilt can be determined based on the actual situation on site.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0024] See also Figure 1-4The present invention provides a technical solution: a ceramic flat membrane blank rapid kiln loading device, comprising two oppositely arranged support plates 1 and a plurality of boron plate material stacks 2 evenly arranged between the inner side walls of the two support plates 1 at equal intervals, a connecting plate 3 is arranged between the bottoms of the two support plates 1, and a receiving space 4 for accommodating the ceramic flat membrane blank is formed between each two adjacent boron plate material stacks 2, and a drawer 5 for stacking a plurality of ceramic flat membrane blanks is slidably arranged in each receiving space 4;

[0025] The boron plate stack 2 is formed by splicing two boron plates 21 and then covering them with at least one mullite hollow plate 22 .

[0026] In this embodiment, in order to avoid the boron plates and columns on the kiln car needing to be repeatedly dismantled and rebuilt each time the ceramic flat membrane blank is loaded into and unloaded from the kiln when the ceramic flat membrane blank is loaded into the kiln for firing, firstly, a plurality of boron plate material stacks 2 are overlapped with two oppositely arranged support plates 1, and the distribution mode of the plurality of boron plate material stacks 2 can be Figure 1 The distribution patterns are evenly spaced from top to bottom, and other distribution patterns are also possible. Figure 1 The distribution method in the boron sheet material can be completed in advance as long as it can be overlapped with the support plate 1. Each boron sheet material stack 2 is composed of two boron sheets 21 spliced ​​together and then covered with at least one mullite hollow sheet 22. That is to say, at least one of the upper and lower surfaces of the two boron sheets 21 spliced ​​together is covered with a mullite hollow sheet 22, which can be single-sided or double-sided. The purpose of the combination of two boron sheets 21 and at least one mullite hollow sheet 22 is to achieve that the ceramic flat membrane blank will not be slightly deformed or displaced during the firing process due to the slight deformation or displacement of the boron sheet during the high temperature process. , which affects the deformation, cracking and other firing quality problems of the ceramic flat membrane blanks. In addition, during the process of loading and unloading the kiln, there is no need to repeatedly dismantle and build boron plates and columns. The bearing surface of the boron plate stack 2 is straight and regular, and is not easily affected by the number of firing times. It avoids the displacement of the boron plate caused by factors such as bumps and vibrations during the movement of the kiln car, thereby affecting the molding of the product. The dismantling and reconstruction of the boron plate stack 2 can be determined according to the actual situation on site. After completing the firing work of each kiln, observe whether the construction structure of the stack is deformed and needs to be rebuilt. After the multi-layer boron plate stack 2 on the kiln car is built, the kiln loading method of the ceramic flat membrane blank can be to stack multiple ceramic flat membrane blanks on the drawer 5. The drawer 2 is made of 1mm thick stainless steel and processed into a drawer shape with an open front end. Through the kiln car accommodating space 4, each stack of ceramic flat membrane blanks is inserted at one time, and then the drawer 5 is pulled out to quickly complete the loading of each layer of blanks. After the firing work is completed, the semi-finished plate can also be directly pulled out through the side of the boron plate pile 2, so that the purpose of not having to remove the boron plate pile 2 when leaving the kiln is achieved.

[0027] Furthermore, the gap between the two boron plates 21 and the mullite hollow plate 22 forms a filling layer 23 , and the filling layer 23 is filled with alumina powder or corundum sand.

[0028] In this embodiment, the surfaces of the covering mullite hollow plate 22 and the two boron plates 21 are rough and uneven, so there will be gaps between the two boron plates 21 and the mullite hollow plate 22. Alumina powder or corundum sand can be used to fill the gaps, that is, the alumina powder or corundum sand can be used to fill the filling layer 23, and the alumina powder or corundum sand are selected with larger particle sizes. Alumina powder has the characteristics of high temperature resistance, corrosion resistance, and stable properties, and corundum sand has the characteristic of high hardness. Therefore, the two boron plates 21 and the mullite hollow plate 22 have strong stability after being combined.

[0029] Furthermore, the upper and lower surfaces of the two boron plates 21 after being spliced ​​are both covered with a mullite hollow plate 22 .

[0030] In this embodiment, two mullite hollow plates 22 are sandwiched between two boron plates 21 after being spliced ​​together, so as to further improve the performance of the boron plate stack 2 .

[0031] Furthermore, the connecting plate 3 is in a concave shape, and the two supporting plates 1 are clamped in the concave of the connecting plate 3 and fit with the two side walls of the concave of the connecting plate 3 respectively.

[0032] In this embodiment, the two support plates 1 are clamped with the concave connecting plate 3, which can increase the stability of the boron sheet stack 2 and the two support plates 1 after overlapping, and avoid the boron sheet stack 2 and the two support plates 1 from spreading out after overlapping.

[0033] Furthermore, a first shock absorbing mechanism 6 is provided at the bottom of the connecting plate 3, and the first shock absorbing mechanism 6 includes a bottom plate 61 in contact with the bottom surface of the connecting plate 3, and side plates 62 are fixedly connected to the opposite sides of the upper surface of the bottom plate 61, and a plurality of first elastic members 63 are evenly fixed on the inner side wall of each side plate 62 at equal intervals, and the ends of the plurality of first elastic members 63 on each side plate 62 are fixedly connected with a pressure plate 64, and the two pressure plates 64 are respectively crimped with the two side walls of the connecting plate 3.

[0034] In this embodiment, during the use of the kiln car, the side panel 62 may shake due to the uneven ground. At this time, the stacked ceramic flat membrane blanks may shake to a certain extent. The first elastic member 63 arranged on both sides absorbs the shaking force of the side panel 62, thereby avoiding the shaking of the stacked ceramic flat membrane blanks. The first elastic member 63 is preferably a shock-absorbing spring, and the elastic force of the shock-absorbing spring is used to weaken the shaking force of the side panel 62.

[0035] Furthermore, a second shock absorbing mechanism 61 is provided on the lower surface of the bottom plate 61, and the second shock absorbing mechanism 61 includes a base 71 located below the bottom plate 61 and arranged at a distance therefrom, and four universal wheels 8 arranged in a matrix are installed on the lower surface of the base 71, and a plurality of telescopic devices 72 are evenly and evenly fixedly connected between the base 71 and the bottom plate 61 at equal intervals, and a second elastic member 73 is sleeved on the outer side of each telescopic device 72, and one end of each second elastic member 73 is fixedly connected to the lower surface of the bottom plate 61, and the other end of each second elastic member 73 is fixedly connected to the upper surface of the base 71.

[0036] In this embodiment, when the amplitude of the kiln car is too large during use, resulting in the first shock absorbing mechanism 6 being insufficient to absorb all the shaking force generated by the side plate 62, the bottom plate 61 will move further downward, and the length of the telescopic device 72 itself will become shorter. The downward movement of the bottom plate 61 will compress the second elastic member 73, and the second elastic member 73 is preferably a spring. The elastic force of the second elastic member 73 absorbs and weakens the shaking force generated by the side plate 62, and the device can move on the bottom surface through the universal wheel 8.

[0037] Furthermore, the telescopic device 72 is a hydraulic cylinder or a telescopic rod.

[0038] In this embodiment, when the telescopic device 72 is a hydraulic cylinder, the output shaft of the hydraulic cylinder will retract under the action of an external controller, so that the downward movement of the base plate 61 will compress the second elastic member 73. When the telescopic device 72 is a telescopic rod, the telescopic rod is a telescopic rod available on the market. The telescopic rod is a prior art. The parts of the telescopic rod itself can slide relatively to change the length of the telescopic rod itself, so that the downward movement of the base plate 61 will compress the second elastic member 73.

[0039] Furthermore, both side walls of the boron sheet material stack 2 are provided with blocks 24 , respectively, and the inner side wall of each support plate 1 is provided with a slot 11 which is interference-fitted with the block 24 .

[0040] In this embodiment, when the boron sheet stack 2 and the support plate 1 are overlapped, the block 24 is inserted into the slot 11, and the block 24 and the slot 11 are interference fit, which can enhance the stability of the boron sheet stack 2 and the support plate 1 after connection.

[0041] Furthermore, the drawer 5 is made of stainless steel.

[0042] In this embodiment, the stainless steel material is high-temperature stainless steel having corrosion resistance or high temperature resistance, general acid medium resistance, heat resistance, and high-temperature oxidation resistance (heat-resistant and non-scaling).

[0043] Furthermore, a handle 51 is provided on the front end surface of the drawer 5 .

[0044] In this embodiment, the handle 51 is convenient for the staff to pull out the drawer 5, so as to quickly complete the filling work of each layer of ceramic flat membrane blanks.

[0045] The working principle and use process of the present invention: After the present invention is installed, firstly, a plurality of boron plate material stacks 2 are overlapped with two relatively arranged support plates 1, and each boron plate material stack 2 is composed of two boron plates 21 spliced ​​together and then covered with at least one mullite hollow plate 22, that is, at least one of the upper surface and the lower surface after the two boron plates 21 are spliced ​​is covered with a mullite hollow plate 22, which can be single-sided or double-sided. The purpose of the combination of two boron plates 21 and at least one mullite hollow plate 22 is to achieve the goal that during the firing process of the ceramic flat membrane blank, the slight deformation or displacement of the boron plate during the high temperature process will not affect the occurrence of firing quality problems such as deformation and cracking of the ceramic flat membrane blank, and during the kiln loading and unloading process, there is no need to repeatedly dismantle and build boron plates and columns. The bearing surface of the boron plate material stack 2 is straight and regular, and is not easily affected by the number of firing times, thereby avoiding the displacement of the boron plate caused by factors such as bumps and vibrations during the movement of the kiln car, thereby affecting the molding of the product.
