Description
Technical Field
[0001] The utility model belongs to the field of ceramic production equipment, and in particular relates to a kiln car with stacked racks. Background Art
[0002] In the production process of ceramics, in order to allow batches of blanks or tiles to be fired at the same time, production operations are often carried out in the form of tunnel kilns. Tunnel kilns are generally long straight tunnels with fixed walls and arches on both sides and the top. A kiln car runs on the track laid at the bottom. The blanks or tiles are placed on the kiln car, and the kiln car is pushed into the tunnel kiln by a cart pusher. The objects on the kiln car are fired by the high temperature in the tunnel kiln. However, the current kiln cars have the following problems. First, the refractory bricks on the kiln car table will expand to the surroundings during use, making the refractory layer of the kiln car larger and larger, causing the two sides of the table to collide with the kiln wall and the refractory brick tables of the front and rear cars to collide, causing damage to the kiln car and affecting the production process due to maintenance. Second, because the hot air in the kiln cannot maintain a good temperature balance when circulating downward, the temperature in the middle and edges of the kiln car is deviated, resulting in different quality of the fired tiles, especially for small objects. Utility Model Content

[0017] The specific implementation of the utility model will be described below in conjunction with the accompanying drawings:
[0018] like Figure 1-4 As shown, a kiln car with a stacked rack 4 includes a car body 1, a refractory layer 2, a frame plate 3 and the rack 4, the car body 1 is provided with a wheel 11 at the bottom, the refractory layer 2 is arranged on the top surface of the car body 1, a limiting plate 21 is provided on the refractory layer 2, the frame plate 3 is matched in the limiting plate 21 and is abutted with the refractory layer 2, a limiting column 31 is provided on the frame plate 3, and a supporting foot 41 is provided at the lower end of the rack 4, and a limiting hole 42 is provided on the supporting foot 41, and the limiting hole 42 cooperates with the limiting column 31.
[0019] The storage rack 4 includes several groups, several of which are provided with snap-fitting grooves 43 on the top surfaces of the storage racks 4, and the storage racks 4 are stacked together by the cooperation of the supporting legs 41 and the snap-fitting grooves 43; the supporting legs 41 include three groups, and the three groups of the supporting legs 41 are distributed in a tripod shape at the lower end of the storage rack 4, and the snap-fitting grooves 43 include six groups, among which three groups of the snap-fitting grooves 43 correspond to the three groups of the supporting legs 41, and the other three groups of the snap-fitting grooves 43 are symmetrical with the first three groups of the snap-fitting grooves 43 with the central axis of the top surface of the storage rack 4 as the symmetry center; the storage rack 4 is also provided with several through holes 44 and several ventilation holes 45, the through holes 44 are arranged in the snap-fitting grooves 43, and several of the through holes 44 are connected to the storage racks 4 respectively, the through holes 44 on the snap-fitting grooves 43 corresponding to the supporting legs 41 are connected to the limiting holes 42, and several of the ventilation holes 45 are arranged on the supporting legs 41, and several of the ventilation holes 45 are connected to the limiting holes 42.
[0020] Furthermore, the refractory layer 2 includes a plurality of refractory bricks 22 and fillers 23 . The plurality of refractory bricks 22 are laid flat on the vehicle body 1 in an array. The gap between the plurality of refractory bricks 22 is 10-15 mm. The fillers 23 are filled in the brick gaps. The limiting plates 21 are arranged on the refractory bricks 22 .
[0021] Description of the working method of this utility model:
[0022] The kiln car with stacked racks 4 of this structure has a car body 1 that can be moved in the tunnel kiln by the wheels 11 at the bottom under the action of a pusher, and the refractory layer 2 on the car body 1 plays a role of separation. The refractory bricks 22 are laid out in an array, and the gap between each refractory brick 22 is 10-15mm. If it is less than 10mm, the refractory bricks 22 will abut against each other during use due to expansion, causing the size of the refractory layer 2 to be enlarged. If it exceeds 15mm, it cannot play a good heat-resistant separation role. Therefore, the gap between the refractory bricks 22 is between 10-15mm, which will have the best effect. At the same time, fillers 23 are filled in the brick joints to ensure that there is no gap between the refractory bricks 22. By setting a gap on the refractory bricks 22 The limiting plate 21 can fix the frame plate 3 on the upper end of the refractory layer 2. In order to prevent the rack 4 from being displaced due to the movement of the kiln car after being placed on the frame plate 3, a limiting column 31 is arranged on the frame plate 3, and a limiting hole 42 cooperating with the limiting column 31 is arranged on the supporting foot 41 of the rack 4. When the rack 4 is placed on the frame plate 3, the limiting hole 42 is inserted into the limiting column 31. The displacement of the rack 4 can be avoided by limiting the rack 4. In order to make the best use of the space in the tunnel kiln and roast more materials in a limited space, several groups of racks 4 are arranged, which are plugged in and fixed by cooperating with the clamping groove 43 on the lower end rack 4 and the supporting foot 41 of the upper end rack 4. The supporting foot 41 The upper racks 4 can be stacked on the frame plate 3 in the same direction or in the opposite direction. In order to achieve uniform heating of the high-temperature air in the tunnel kiln between the racks 4, ventilation holes 45 are provided on the support legs 41. The air in the upper layer of the racks 4 can enter the lower layer through the through holes 44 and the ventilation holes 45, so that air circulation and uniform heating in the racks 4 can be achieved. When all the racks 4 are stacked in the same direction, the support legs 41 are stacked from top to bottom, and the through holes 44 penetrate the support legs 41 on each rack 4 from top to bottom. This stacking method can keep the supporting force of each layer of the racks 4 supported by the support legs 41, which is suitable for placing heavy objects for use. However, this method The air flow direction between each layer of the type is single, and most of the air will flow through the through holes 44, and a small part will flow through the ventilation holes 45 on the supporting legs 41. It is impossible to achieve uniform air flow in each layer. Stacking is convenient, but the roasting effect will be poor. When each layer of the rack 4 is stacked in a staggered direction, the supporting legs 41 of each layer are staggered and separated. In this stacking method, the supporting legs 41 of each layer of the rack 4 are staggered, which is suitable for placing lighter materials. Since the air circulation in this method will flow from top to bottom on the supporting legs 41 of each layer, and the supporting legs 41 are distributed in a tripod shape, the air of each layer will completely flow through the top surface of the rack 4, achieving uniform air flow, so that the roasting effect will be better.But the disadvantage is that only light objects can be roasted.
[0023] The beneficial effect of the utility model is that the limiting columns 31 on the frame plate 3 cooperate with the limiting holes 42 of the supporting feet 41 on the rack 4 to fix the rack 4, so as to avoid the rack 4 being displaced or tipped over due to the shaking caused by the kiln car moving forward. At the same time, the stacked racks 4 are limited and fixed at each layer by the cooperation of the supporting feet 41 and the clamping grooves 43, so as to ensure that the racks 4 at each layer can remain stable. In order to achieve uniform heating of the air in the tunnel kiln between the racks 4, the air on the upper layer of the rack 4 is circulated into the rack 4 on the next layer through the arrangement of the through holes 44 and the ventilation holes 45, so as to achieve air circulation and uniform heating in the racks 4.
