Description

Technical Field

[0001] The present application relates to the technical field of ceramsite production, and in particular to a ceramsite production line. Background Art

[0002] Claydite is a lightweight aggregate produced by foaming in a rotary kiln. It has a spherical shape, a smooth and hard surface, a honeycomb interior, and is characterized by low density, low thermal conductivity, and high strength. In the refractory industry, ceramsite is mainly used as aggregate for thermal insulation refractory materials.

[0003] A rotary kiln is a rotating calcining kiln that consists of processes such as gas flow, fuel combustion, heat transfer and material movement. In the production of ceramsite, the rotary kiln is an indispensable processing equipment.

[0004] However, the rotary kiln used for producing ceramsite in the related art is usually directly fixed on the ground, and since the rotary kiln is large in size and difficult to move, the space utilization rate of the ceramsite production workshop is low. Summary of the invention

[0005] In order to improve the problem of low space utilization in a ceramsite production workshop, the present application provides a ceramsite production line, which adopts the following technical solution: a ceramsite production line, comprising a rotary kiln and a number of concrete columns arranged in a workshop, wherein the several concrete columns are arranged at the same height, the rotary kiln is arranged on the several concrete columns, and the outer edges of the several concrete columns are also connected to maintenance passages, the maintenance passages are located below the rotary kiln, and the maintenance passages are also provided with guardrails.

[0006] Through the above technical scheme, after the rotary kiln is erected above several pillars, the staff can pass through the pillars below the rotary kiln, and other processing equipment can also be placed on the ground below the rotary kiln, thereby improving the space utilization rate of the expanded clay production workshop; the setting of the maintenance passage allows the staff to regularly go up to the maintenance passage, and then inspect or maintain the rotary kiln above the maintenance passage. The setting of the guardrail has the function of protecting the maintenance personnel, reducing the possibility of the maintenance personnel accidentally falling from the maintenance passage, and reducing the safety hazards during the maintenance process.

[0007] Preferably, a plurality of support columns are vertically penetrated in the column, a plurality of the support columns partially extend out of concrete columns toward one end of the rotary kiln, a plurality of the support columns are provided with support plates, an isolation cavity is formed between the support plates and the concrete columns, and the rotary kiln is mounted on the support plates.

[0008] Through the above technical solution, the concrete column will stably support the support plate through a number of support columns, so that the rotary kiln can be stably supported by the support plate above the concrete column. The setting of the support plate has the effect of separating the rotary kiln from the concrete column, so that the heat energy at the rotary kiln needs to pass through the isolation cavity before it can be transferred to the upper end surface of the concrete column. The setting of the isolation cavity increases the loss of heat energy when it is conducted toward the concrete column, reduces the possibility of heat energy during the operation of the rotary kiln being directly transferred to the concrete column and causing cracks in the concrete column, thereby enhancing the structural stability of the concrete column.

[0009] Preferably, a plurality of heat insulation boards are provided in the isolation cavity, a plurality of metal rods are passed through the heat insulation boards in a horizontal direction, and both ends of the metal rods partially extend out of the heat insulation boards.

[0010] Through the above technical solution, when the rotary kiln transfers heat energy through the isolation cavity toward the concrete column, the insulation board has a heat insulation effect, which increases the loss of heat energy when passing through the isolation cavity and reduces the possibility of cracking of the concrete column due to high temperature; the arrangement of the metal rod enables the heat energy conducted into the insulation board to be quickly dissipated out of the isolation cavity along the metal rod, further increasing the loss of heat energy when passing through the isolation cavity, thereby further reducing the possibility of cracking of the concrete column.

[0011] Preferably, a first metal plate is provided on the end surface of the support plate facing away from the rotary kiln, the peripheral edge of the first metal plate extends out of the support plate, and a second metal plate is provided along the peripheral edge of the support plate, and the second metal plate is connected to the first metal plate.

[0012] Through the above technical solution, the heat on the support plate can be quickly dissipated along the first metal plate and the second metal plate. The arrangement of the first metal plate and the second metal plate increases the heat dissipation effect of the support plate, further reduces the heat energy value conducted from the rotary kiln to the isolation cavity, and further reduces the heat energy value conducted from the rotary kiln to the concrete column, thereby further reducing the possibility of cracking of the concrete column.

[0013] Preferably, the expanded clay production line according to claim 4 is characterized in that a plurality of flow grooves are respectively provided on the first metal plate and the second metal plate, and the plurality of flow grooves are arranged in a staggered manner horizontally and vertically.

[0014] Through the above technical solution, the setting of the flow channel groove has the function of guiding the external airflow, so that the external airflow can flow along the horizontal and vertical crisscrossing flow channel grooves, so that the heat on the first metal plate and the second metal plate can be dissipated faster under the drive of the airflow, thereby further enhancing the heat dissipation effect at the support plate.

[0015] Preferably, the outer edge of the concrete column is coated with a waterproof mortar layer, and the end surface of the waterproof mortar layer facing away from the concrete column is an arc-shaped surface.

[0016] Through the above technical scheme, the setting of the waterproof mortar layer has a waterproof effect, which makes it difficult for the concrete column to crack due to the rapid evaporation of internal moisture, thereby achieving the effect of protecting the concrete column; at the same time, the moisture falling on the concrete can be quickly discharged along the curved surface of the waterproof mortar layer, reducing the possibility of the concrete column being corroded by accumulated water, thereby further enhancing the protective effect on the concrete column.

[0017] Preferably, a plurality of reinforcing ribs are provided along the periphery of the concrete column, the plurality of reinforcing ribs are arranged in a staggered manner horizontally and vertically, and the distribution density of the plurality of reinforcing ribs gradually decreases downward along the vertical direction.

[0018] Through the above technical scheme, the arrangement of a plurality of reinforcing ribs strengthens the structural strength of the concrete column itself and reduces the possibility of cracking of the concrete column under the action of external force, so that the concrete column can stably support the rotary kiln; at the same time, the arrangement of a plurality of reinforcing ribs also has the function of heat dissipation, so that the heat energy conducted to the concrete can be quickly dissipated along the plurality of reinforcing ribs, thereby strengthening the heat dissipation effect of the concrete column itself.

[0019] Preferably, a water spray pipe is provided along the periphery of the concrete column, the water spray pipe is located above the inspection channel, a plurality of atomizing nozzles are connected to the water spray pipe, and the plurality of atomizing nozzles are arranged toward the outer edge of the concrete column. A water tank and a water pump are also provided on the inspection channel, the water inlet end of the water pump is connected to the water tank, and the water outlet end of the water pump is connected to the water spray pipe. A temperature sensor is also provided on the reinforcement rib, and the temperature sensor is connected to the water pump.

[0020] Through the above technical solution, when the temperature of the reinforcement is higher than the trigger value of the temperature sensor, the temperature sensor will be triggered and linked with the water pump to start the water pump. When the water pump starts, the water in the water tank will be pumped into the water pipe, and then sprayed onto the reinforcement and concrete columns from a number of atomizing nozzles to cool the concrete columns, thereby further reducing the possibility of cracking of the concrete columns due to high temperature.

[0021] Preferably, an annular drain seat is provided along the periphery of the concrete column, the drain seat is pressed against the ground and the end surface facing away from the ground is arranged as an inclined surface, and the inclined surface is arranged in a direction away from the concrete column.

[0022] Through the above technical solution, when the water on the reinforcing bars and concrete columns slides down to the drain seat at the bottom of the concrete column, it will quickly slide down along the inclined surface under the guidance of the inclined surface of the drain seat, thereby reducing the possibility of water accumulation at the bottom of the concrete column causing the concrete column to be corroded by the accumulated water, thereby affecting the structural strength of the concrete column itself.

[0023] Preferably, the outer edge of the water spray pipe is coated with a sound insulation layer, and the outer edge of the sound insulation layer is coated with a heat insulation layer.

[0024] Through the above technical scheme, the setting of the sound insulation layer has the effect of sound insulation and noise reduction, which reduces the noise when the water flows along the water spray pipe and improves the factory environment; the setting of the thermal insulation film has the function of protecting the sound insulation layer and the water spray pipe, making the sound insulation layer and the water spray pipe not easily twisted and deformed due to high temperature, so that the water can flow stably along the water spray pipe.

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-7 This application is described in further detail.

[0037] The embodiment of the present application discloses a ceramsite production line.

[0038] Example 1

[0039] like Figure 1 As shown, it comprises a rotary kiln 1 and several concrete columns 2 fixedly arranged in a workshop. The length of the rotary kiln is 82.9 meters, so that the waste heat generated during the heating process in the rotary kiln can flow along the rotary kiln, thereby achieving the effect of waste heat recycling; at the same time, the 82.9-meter length of the rotary kiln increases the amount of raw materials entering the kiln, so that the rotary kiln can process more raw materials at one time, saving energy and reducing emissions; the upper end surfaces of the several concrete columns 2 are at the same height, and the rotary kiln 1 is fixedly mounted on the upper end surfaces of the several concrete columns 2; An inspection passage 3 is also connected to the outer edge, and the inspection passage 3 is located below the rotary kiln 1, so that the staff can easily inspect or maintain the rotary kiln 1 with the help of the inspection passage 3; a guardrail 4 is fixedly arranged on the outer edge of the inspection passage 3, and the setting of the guardrail 4 has the function of protecting the inspection personnel and reducing the potential safety hazards during the inspection process; at the same time, the rotary kiln 1 is stably supported above the workshop by a number of concrete columns 2, so that the staff can reasonably use the space between the concrete columns 2 below the rotary kiln 1, thereby improving the space utilization rate of the ceramsite production workshop.

[0040] The implementation principle of Example 1 is as follows: a plurality of concrete columns 2 are used to support the rotary kiln 1, so that the rotary kiln 1 is fixedly placed in the upper space of the workshop, so that the space in the lower part of the workshop in contact with the ground can be used for other purposes, which reduces the possibility that when the rotary kiln 1 is fixed on the workshop floor, it is difficult for the staff to use the space above the rotary kiln 1, resulting in insufficient available space inside the workshop, thereby improving the space utilization rate of the expanded clay production workshop.

[0041] Example 2

[0042] like Figure 2 and Figure 3As shown, the difference between this embodiment and embodiment 1 is that it also includes a control system, a plurality of support columns 5 are evenly penetrated in the concrete column 2 in the vertical direction, the support columns 5 partially extend out of the concrete column 2 toward one end of the rotary kiln 1, and the upper end surfaces of the plurality of support columns 5 are flush, support plates 6 are fixedly mounted on the plurality of support columns 5 in the horizontal direction, the rotary kiln 1 is fixedly mounted on the plurality of support plates 6, an isolation cavity 7 is formed between the support plates 6 and the concrete column 2, the isolation cavity 7 is filled with a plurality of insulation boards 8, the insulation boards 8 are made of glass wool boards, and the glass panels have good thermal insulation and heat insulation properties.

[0043] like Figure 2 and Figure 3 As shown, the two end faces of the heat insulation board 8 in the vertical direction are in contact with the concrete column 2 and the support plate 6 respectively. Therefore, when the heat generated during the operation of the rotary kiln 1 is transferred to the direction of the concrete column 2, it will first pass through the support plate 6 and the isolation cavity 7. The support plate 6 will initially intercept the heat conducted in the direction of the concrete, and the several heat insulation boards 8 in the isolation cavity 7 will further intercept the heat, thereby reducing the temperature of the upper end face of the concrete column 2 when the rotary kiln 1 is working, reducing the possibility of cracking of the concrete column 2 due to being in a high temperature state for a long time, and increasing the service life of the concrete column 2, so that the concrete column 2 can stably support the rotary kiln 1 for a long time.

[0044] like Figure 2 and Figure 3 As shown, a first metal plate 10 is bonded to the end surface of the support plate 6 facing the concrete column 2, and the outer edge of the first metal plate 10 extends out of the support plate 6, and a second annular metal plate 11 is bonded to the support plate 6 along the periphery, and the second metal plate 11 is fixedly connected to the upper end surface of the first metal plate 10. A metal rod 9 is also penetrated in the horizontal direction in the plurality of heat insulation plates 8, and the two ends of the metal rod 9 extend out of the heat insulation plate 8 and are fixedly connected to the first metal plate 10, and the first metal plate 10, the second metal plate 11 and the metal rod 9 can be made of aluminum or steel. Therefore, the first metal plate 10, the second metal plate 11 and the metal rod 9 constitute a heat dissipation network that is interconnected, and the heat dissipation performance of the support plate 6 and the heat insulation plate 8 is enhanced, so that the heat in the support plate 6 and the heat insulation plate 8 can be quickly discharged along the first metal plate 10, the second metal plate 11 and the metal rod 9, thereby enhancing the heat interception effect of the support plate 6 and the heat insulation plate 8, and further reducing the possibility of the concrete column 2 cracking due to the high temperature generated when the rotary kiln 1 is working.

[0045] like Figure 4As shown, a plurality of flow grooves 12 are evenly provided on the end surface of the second metal plate 11 facing away from the support plate 6, and the plurality of flow grooves 12 are arranged in a staggered manner in a horizontal and vertical direction. The first metal plate 10 is also provided with a plurality of corresponding flow grooves 12 in a staggered manner in a horizontal and vertical direction, and the longitudinal flow grooves 12 on the first metal plate 10 and the second metal plate 11 are interconnected; the arrangement of the flow grooves 12 has the function of guiding external airflow, so that airflow in all directions of the outside world can flow along the plurality of flow grooves 12, so that the heat energy on the first metal plate 10 and the second metal plate 11 can be dissipated faster driven by the airflow, thereby further enhancing the heat dissipation effect of the support plate 6.

[0046] like Figure 5 As shown, a number of reinforcing ribs 14 staggered in horizontal and vertical directions are fixed on the outer edge of the concrete column 2. The reinforcing ribs 14 can be made of steel. The number of longitudinally arranged reinforcing ribs 14 are arranged at equal distances, and the distribution density of the number of transversely arranged reinforcing ribs 14 gradually decreases from top to bottom. Therefore, the number of reinforcing ribs 14 wrapped around the outer edge of the concrete column 2 has the effect of reinforcing the structure of the concrete column 2, further reducing the possibility of the concrete column 2 cracking under the influence of high temperature; at the same time, the reinforcing ribs 14 themselves also have good thermal conductivity, so that the heat of the concrete column 2 itself can be quickly dissipated to the outside air along the number of reinforcing ribs 14, thereby enhancing the heat dissipation effect of the concrete column 2 and reducing the possibility of the concrete column 2 cracking due to the accumulation of heat in the concrete column 2 and the difficulty in timely discharge.

[0047] like Figure 5 As shown, a water tank 17 and a water pump 18 are fixedly connected to the inspection channel 3, respectively. The water pump 18 is controlled by a control system. An annular water spray pipe 15 is fixedly provided on the reinforcing rib 14. The water inlet end of the water pump 18 is connected to the water tank 17, and the water outlet end is connected to the water spray pipe 15. The water spray pipe 15 is evenly connected to a plurality of atomizing nozzles 16, and the water outlet ends of the plurality of atomizing nozzles 16 are all arranged toward the outer edge of the concrete column 2.

[0048] like Figure 5As shown, a temperature sensor 19 is also installed on the reinforcing rib 14, and the temperature sensor 19 is connected to the control system. When the temperature on the surface of the reinforcing rib 14 is higher than the trigger value of the temperature sensor 19, the temperature sensor 19 will be triggered and send a feedback signal to the control system. After receiving the feedback signal from the temperature sensor 19, the control system will synchronously control the water pump 18 to start. Therefore, when the temperature of the outer edge of the concrete is higher than the preset value of the temperature sensor 19, the temperature sensor 19 will be triggered and the water pump 18 will be controlled by the control system to start. When the water pump 18 starts, the water in the water tank 17 will be pumped into the water spray pipe 15, and then the water in the water spray pipe 15 will be sprayed onto the outer edge of the concrete column 2 and the reinforcing rib 14 through a plurality of atomizing nozzles 16, so as to cool down the concrete column 2 and the reinforcing rib 14, thereby further reducing the possibility of cracking of the concrete column 2 due to high temperature.

[0049] like Figure 6 As shown, a waterproof mortar layer 13 is coated on the outer edge of the concrete column 2. The setting of the waterproof mortar layer 13 has a waterproof effect, so that the moisture inside the concrete column 2 is not easy to quickly dissipate from the concrete column 2 under high temperature, so that the concrete column 2 is not easy to crack due to rapid loss of moisture; the end face of the waterproof mortar layer 13 facing the support plate 6 is set as an arc surface, and the arc surface is set high in the middle and low around. The bottom of the concrete column 2 is also fixed with an annular drainage seat 20 along the periphery, and the lower end face of the drainage seat 20 is fixedly connected to the ground, and the upper end face of the drainage seat 20 is an inclined surface 21 arranged downwardly, and the inclined surface 21 is arranged in a direction away from the concrete column 2. Therefore, the water on the top of the concrete column 2 will quickly flow along the curved surface to the outer edge of the concrete column 2, and then merge with the water on the outer edge of the concrete column 2 and fall to the drain seat 20. The inclined surface 21 on the drain seat 20 has the function of guiding the accumulated water, so that the water gathered on the outer edge of the concrete column 2 can quickly flow out of the concrete column 2 along the inclined surface 21, thereby preventing the bottom of the concrete column 2 from being easily damaged by corrosion due to accumulated water.

[0050] like Figure 5 and Figure 7 As shown, the outer edge of the water spray pipe 15 is bonded and coated with a sound insulation layer 22, which can be made of a sound-absorbing film. The sound-absorbing film is a colorless and transparent sound-absorbing material that has the function of absorbing and degrading low-frequency noise; when the water pump 18 is started to pump the water in the water tank 17 into the water spray pipe 15, the sound insulation layer 22 has the function of absorbing and reducing noise, thereby reducing the possibility of water flowing along the water spray pipe 15 and making noise that affects the workshop environment; the outer edge of the sound insulation layer 22 is also bonded and coated with a heat insulation layer 23, which can be made of glass fiber. The setting of the heat insulation layer 23 has the function of heat insulation, thereby reducing the possibility of the water spray pipe 15 and the sound insulation layer 22 being twisted and deformed due to high temperature, thereby achieving the effect of protecting the water spray pipe 15 and the sound insulation layer 22.

[0051] The implementation principle of Example 2 is as follows: the heat energy generated during the operation of the rotary kiln 1 will pass through the support plate 6 and the isolation chamber 7 in sequence during the process of being conducted to the concrete column 2. The support plate 6 will initially block the heat, and the heat on the support plate 6 can also be quickly dissipated into the air along the first metal plate 10 and the second metal plate 11. The heat insulation plate 8 in the isolation chamber 7 will block the heat passing through the support plate 6, and the heat in the isolation chamber 7 can also be quickly dissipated into the air along the metal rod 9 passing through the isolation chamber 7, thereby reducing the heat energy value conducted to the concrete column 2, reducing the possibility of cracking of the concrete column 2 due to high temperature, and improving the service life of the concrete column 2.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
