Description

Technical Field

[0001] The utility model belongs to the technical field of production equipment for unburned bricks, and in particular relates to a kiln system for curing unburned bricks. Background Art

[0002] Unburned bricks refer to a new type of building material made from fly ash, coal slag, coal gangue, tailings, chemical slag or natural sand, sea mud, etc. (one or more of the above raw materials) as the main raw materials without high-temperature calcination. They are often used in building walls, floor paving and other scenes. Unburned bricks are pressed and formed by brick machine equipment. Specifically, the mixed blank is injected into the lower mold, and then the upper mold is lowered to close the mold and a certain vibration is applied. The brick blank is pressed and formed. After demolding, the brick blank needs to be transferred to the curing site for a certain process time. During the curing process, the brick blank gradually builds up structural strength and forms the final unburned brick product.

[0003] With the development of technology, the efficiency of brick processing of brick machines and equipment has been increasing, and the production efficiency of brick production lines has also been increasing. Therefore, the traditional method of using vehicles to transfer pressed bricks to maintenance sites can no longer meet the needs of large-scale unburned brick production. On the other hand, as the scale of unburned brick production becomes larger and larger, the maintenance site's capacity to accommodate bricks has also put forward higher and higher requirements. People are eager to make fuller use of the three-dimensional space and reduce the floor space of the maintenance site. In summary, it is necessary to develop and design a new type of maintenance kiln system. Utility Model Content

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given to explain in detail.

[0024] See also Figure 1 and Figure 2 The utility model of the unfired brick curing kiln system comprises a curing kiln 1, in which curing brackets 3 are arranged at equal intervals, and between adjacent curing brackets 3 there are multi-layer curing spaces for placing brick trays 13, and kiln inner rails 6 are installed on the ground of the curing kiln 1 and between the roots of adjacent curing brackets 3.

[0025] like Figure 1 As shown in the figure, the curing kiln 1 is a semi-enclosed structure, which is open only at the front. The brick tray 13 is placed in the kiln from the front and taken out from the kiln from the front. A top guardrail 2 is installed at the top edge of the curing kiln 1, and a staircase 12 leading to the top is installed on the side of the curing kiln 1, so that the top of the curing kiln 1 can be climbed through the staircase 12, and maintenance work such as laying waterproofing and other construction can be carried out in the space inside the top guardrail 2.

[0026] In this embodiment, the curing bracket 3 includes a bracket longitudinal beam 3-1 installed between the top wall of the curing kiln 1 and the ground, and a supporting angle steel 3-2 is installed on the bracket longitudinal beam 3-1 to support the brick blank tray 13, that is, the curing bracket 3 is a steel structure. The brick blank tray 13 includes a brick blank and a tray to support the brick blank. When the brick blank tray 13 is placed in a certain layer of curing space between the curing brackets 3, the tray edge of the brick blank tray 13 is supported by the supporting angle steel 3-2.

[0027] A kiln-front ditch 4 is provided on the ground in front of the curing kiln 1, in which a ditch inner rail 5 arranged along the length direction is provided, and the ditch inner rail 5 is perpendicular to the kiln inner rail 6; a ditch-front rail 8 is provided in front of the kiln-front ditch 4, and the ditch-front rail 8 is perpendicular to the ditch inner rail 5, that is, the ditch-front rail 8 is parallel to the kiln inner rail 6.

[0028] A hoist 9 is installed at the front end of the trench front rail 8, a shuttle vehicle 10 that can move back and forth is provided on the trench inner rail 6, and a placement and transfer device 7 that can move to the kiln inner rail 6 and the trench front rail 8 is provided on the shuttle vehicle 10. The placement and transfer device 7 transports or transfers out the brick pallet 13 to the curing bracket 3, and the placement and transfer device 7 transports or transfers out the brick pallet 13 to the hoist 9.

[0029] The operating principle is: the elevator 9 is set at the end of the unfired brick output line, and the brick blank pallet 13 discharged by the brick machine equipment moves along the brick output line to the end. When it moves to the elevator 9, the elevator 9 receives one brick blank pallet 13 at a time and then moves upward one station. The next brick blank pallet 13 continues to be received by the elevator 9. This is repeated to complete the reception and lifting of multiple brick blank pallets 13. After that, the transfer-out device 7 is placed in the elevator 9 to receive multiple brick blank pallets 13 and place these brick blank pallets 13 in the space between adjacent curing brackets 3 in the curing kiln 1 at the same time. When the transfer-out device 7 exits, each brick blank pallet 13 falls on the supporting angle steel 3-2 of the curing bracket 3.

[0030] See also Figure 3 and Figure 4 , we can see that:

[0031] The ferry vehicle 10 includes a ferry chassis 10-1 with rollers, the rollers are located on the inner rails 5 of the trench, and a travel drive (not shown in the figure) and a slewing drive device 10-2 with a slewing track 10-3 are also installed on the ferry chassis 10-1, and the insertion and rotation device 7 is located on the slewing drive device 10-2. Driven by the travel drive, the ferry vehicle 10 moves back and forth along the inner rails 5 of the trench, and the slewing drive device 10-2 can drive the insertion and rotation device 7 to rotate, so that the insertion and rotation device 7 can rotate 180° after receiving the brick tray 13 from the hoist 9, and after rotating and adjusting the direction, the insertion and rotation device 7 drives onto the inner rails 6 of the kiln again, and delivers the brick tray 13 into the curing space between the curing brackets 3.

[0032] In this embodiment, the slewing drive device 10-2 includes a slewing chassis, a slewing track 10-3 is fixedly mounted on the slewing chassis, a slewing drive machine (not shown in the figure) is mounted on the slewing chassis and a slewing drive gear (not shown in the figure) is mounted on its output shaft, a fixed gear is mounted on the ferry chassis 10-1, and the slewing drive gear meshes with the fixed gear for transmission. When it is necessary to rotate the insertion and extraction device 7 by 180°, the slewing drive machine drives the slewing drive gear to rotate, and through the cooperation between the slewing drive gear and the fixed gear, the slewing chassis and its auxiliary mechanisms rotate, and since the insertion and extraction device 7 is parked on the slewing track 10-3 of the slewing drive device 10-2, the insertion and extraction device 7 realizes the rotation action.

[0033] See also Figure 3 , we can see that:

[0034] The insertion and removal device 7 includes a transport vehicle 7-1 located on the revolving track 10-3 of the shuttle vehicle 10, a main frame 7-3 is installed on the transport vehicle 7-1, and a multi-layer support beam 7-2 is installed from top to bottom in front of the main frame 7-3. The transport vehicle 7-1 is an autonomous vehicle, including a transport chassis, rail wheels installed on the transport chassis, and a driving machine for driving the rail wheels to rotate. When the revolving drive device 10-2 of the shuttle vehicle 10 rotates to the position where the revolving track 10-3 is connected to the kiln inner rail 6, the driving machine of the transport vehicle 7-1 is activated, and the transport vehicle 7-1 carries the main frame 7-3 and the attached parts onto the kiln inner rail 6, and returns to the original position after completing the placement operation of the brick blank tray 13.

[0035] In this embodiment, a positioning guide roller 7-4 is also installed on the top of the main support 7-3, and a positioning guide track 11 with its front end exposed is provided on the top wall of the curing kiln 1. The positioning guide roller 7-4 is first connected with the positioning guide track 11 before the insertion and transfer device 7 is driven onto the kiln inner rail 6. The positioning guide roller 7-4 and the positioning guide track 11 are provided to calibrate the position of the insertion and transfer device 7. When the upper positioning guide roller 7-4 is connected with the positioning guide track 11, the bottom conveyor 7-1 can be smoothly transferred to the kiln inner rail 6.

[0036] See also Figure 5 , we can see that:

[0037] The elevator 9 includes a frame 9-1, the bottom of which is fixed on the ground. Two groups of chains are installed on the frame 9-1, and each group of chains is installed with a plurality of equally spaced supporting angle steels for supporting the brick pallet. A lifting component for driving the two groups of chains to move synchronously in the opposite direction is also installed on the frame 9-1. As shown in the figure, when the brick pallet 13 moves into the elevator 9, the bottom of the brick pallet 13 is supported by two supporting angle steels of equal height on the left and right. In the process of the lifting component driving the two groups of chains to move synchronously in the opposite direction, the brick pallet 13 is lifted layer by layer. When it reaches the height, the lifting component drives the two groups of chains to move synchronously in the opposite direction. Figure 5 In the state shown in , the elevator 9 is fully loaded, at which time the brick discharging line and the elevator 9 are both suspended, and the transfer device 7 is placed close to the elevator 9 to extract and transfer the multiple brick trays 13 on the elevator 9.

[0038] like Figure 5As shown in , a left driving shaft is installed at the top and bottom of the left side of the frame 9-1 and two first chains 9-4 are installed between the left driving shafts, a right driving shaft is installed at the top and bottom of the right side of the frame 9-1 and two second chains 9-6 are installed between the right driving shafts, a first supporting angle steel 9-5 is installed between the two first chains 9-4, and a second supporting angle steel 9-7 is installed between the two second chains 9-6. A first lifting motor 9-2 driving the left top driving shaft and a second lifting motor 9-3 driving the right top driving shaft are installed at the top of the frame 9-1. The first lifting motor 9-2 and the second lifting motor 9-3 act synchronously, and the left driving shaft and the right driving shaft rotate in opposite directions, so the first chain 9-4 and the second chain 9-6 rotate synchronously in opposite directions, and correspondingly, each group of first supporting angle steel 9-5 and second supporting angle steel 9-7 shift synchronously.

[0039] Running process:

[0040] The elevator 9 is installed at the end of the brick production line. The brick blanks pressed and formed by the brick machine equipment are located on the pallet to form a brick blank pallet 13. When the brick blank pallet 13 moves to the end of the brick production line, the two ends of the pallet are located on a set of first supporting angle steels 9-5 and second supporting angle steels 9-7 of equal height. The first lifting motor 9-2 and the second lifting motor 9-3 are running, and the first chain 9-4 and the second chain 9-6 move synchronously. Then, the first supporting angle steel 9-5 and the second supporting angle steel 9-7 carry the brick blank pallet 13 and move it up one station. When the next brick blank pallet 13 moves into place, the aforementioned lifting operation is repeated until it reaches Figure 5 The full load state shown in , at this time the brick delivery line and the elevator 9 are suspended;

[0041] The shuttle bus 10 carries the placement and transfer device 7 and moves along the inner rail 5 of the trench until the rotary track 10-3 is aligned with the trench front rail 8. The rotary drive device 10-2 is activated to adjust the posture of the placement and transfer device 7 so that the multi-layer support beams 7-2 face the elevator 9. When the placement and transfer device 7 is sufficiently close to the elevator 9, the support beams 7-2 of each layer are transferred to the bottom of each brick tray 13. At this time, the chain of the elevator 9 is displaced in the reverse direction, and each brick tray 13 falls on the support beams 7-2 of each layer. Then, the placement and transfer device 7 is retracted to the shuttle bus 10, and then the rotary drive of the shuttle bus 10 is activated. The device 10-2 is actuated to rotate the placement and transfer device 7 by 180°, so that each layer of support beams 7-2 face the direction of the curing kiln 1; then the shuttle bus 10 carries the placement and transfer device 7 and moves it to a suitable position along the inner rail 6 of the trench. At this time, the rotary track 10-3 is aligned with the inner rail 6 of a kiln, and the placement and transfer device 7 moves to the inner rail 6 of the kiln, and drives to a suitable position inside the curing kiln 1 along the inner rail 6 of the kiln. Each brick tray 13 is placed in the multi-layer curing space between adjacent curing brackets 3, that is, each brick tray 13 is supported by the supporting angle steel 3-2 of the curing bracket 3;

[0042] After that, the transfer device 7 is placed back on the ferry vehicle 10, and the aforementioned action process is repeated to continuously transfer the brick trays 13 on the brick discharge line into the curing kiln 1;

[0043] The brick pallets 13 after curing are also taken out of the curing kiln 1 by the shuttle bus 10 and the placement and transfer device 7. Another elevator 9 can be set up at the production site, and the placement and transfer device 7 can transfer multiple brick pallets 13 to the elevator 9 at the same time. Thereafter, each brick pallet 13 on the elevator 9 is lowered layer by layer onto a brick packaging line and moved to the brick stacking and packaging process.
