Technical Field

[0001] The utility model relates to the technical field of preparing concrete from coal gasification slag, and in particular, to a sorting device and a concrete preparation system. Background Art

[0002] With the rapid development of the coal chemical industry in China, in order to make full use of energy, the coal gasification slag has abandoned the methods of stacking and landfill for treatment. The traditional treatment methods not only cause environmental problems such as land occupation, dust pollution, water and soil pollution, but also generate a large amount of disposal costs.

[0003] At present, in order to make full use of the coal gasification slag, the coal gasification slag is usually added to the concrete for use. Since the particles of the coal gasification slag generated during the gasification process are of different sizes, especially the smaller particles of the coal gasification slag, direct application will affect the quality of the concrete. In the prior art, a sorting device is usually used to screen the coal gasification slag with larger particle diameters, and then the sorted coal gasification slag is put into the production line for concrete preparation. However, during the transfer process of the coal gasification slag to the preparation production line, it is also necessary to weigh a certain amount of the coal gasification slag, and the process is relatively cumbersome, and a large number of application devices are required, which affects the production efficiency of the concrete.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0029] As Figure 1 shown, the embodiment of the present invention provides a sorting device, which includes a material box 10, a sieve mesh 20, a vibration motor 30 and a control component. Among them, the material box 10 has a discharge port and a storage cavity 11, and a blocking member is arranged at the discharge port; the sieve mesh 20 is inclined and arranged in the storage cavity 11, and the sieve mesh 20 is used for screening coal gasification slag; the vibration motor 30 is drivingly connected to the sieve mesh 20 to drive the sieve mesh 20 to vibrate; the control component includes a driving member, a weight sensor 40 and a controller. The driving member is drivingly connected to the blocking member, and the driving member is used to drive the blocking member to open or block the discharge port. The controller is electrically connected to the driving member and the weight sensor 40 respectively. The weight sensor 40 is arranged on the sieve mesh 20 to detect the weight of the coal gasification slag that has not passed through the screening of the sieve mesh 20. When the weight of the coal gasification slag that has not passed through the screening of the sieve mesh 20 meets the preset weight range, the controller can control the blocking member to open the discharge port.

[0030] Applying the technical solution of the present utility model, the sorting device includes a material box 10, a screen 20, a vibration motor 30 and a control component. The storage cavity 11 of the material box 10 can store the coal gasification slag generated during the coal gasification process. The vibration motor 30 can drive the screen 20 to vibrate, so as to sort out the coal gasification slag with a smaller particle diameter through the screen 20, so as to ensure that the particle diameter of the coal gasification slag entering the concrete preparation system can be maintained within a certain range, so as to ensure the quality of the concrete. By obliquely arranging the screen 20 in the storage cavity 11, after the screening is completed, the vibration motor 30 continues to vibrate, so that the coal gasification slag that has not passed through the screen 20 can be discharged from the storage cavity 11 through the discharge port, realizing feeding; and, the weight sensor 40 arranged on the screen 20 can detect the weight of the coal gasification slag on the screen 20. By setting the parameters of the controller in combination with the feeding amount, when the weight of the remaining coal gasification slag on the screen 20 reaches the weight parameter required to enter the concrete preparation system, the controller can control the driving part to open the discharge port through the control, so that the coal gasification slag on the screen 20 enters the concrete preparation system, so as to realize automatic quantitative feeding, without setting a weighing process between the sorting process and the transfer process, simplifying the overall production steps, realizing the feeding of the coal gasification slag, and improving the production efficiency of concrete preparation.

[0031] In a specific embodiment of the present application, the blocking member includes a turning plate 50. A rotating shaft 12 extending in the horizontal direction is provided on the inner wall of the material box 10. The turning plate 50 is fixedly connected to the rotating shaft 12, and the driving part is drivingly connected to the rotating shaft 12. The driving part can drive the top end of the turning plate 50 to rotate around the rotating shaft 12 away from the discharge port to open the discharge port. Through the above setting, the turning plate 50 can avoid the discharge port after rotation, and the coal gasification slag can be discharged from the storage cavity 11 through the discharge port, realizing feeding.

[0032] Specifically in the present application, the discharge port is arranged on the side wall of the material box 10, or can be integrally formed by a certain side wall in the circumferential direction of the material box 10.

[0033] When the blocking member is the turning plate 50, the driving part can be a rotating motor, and the power output end of the rotating motor is fixedly connected to the rotating shaft to drive the turning plate 50 to rotate through the rotating shaft.

[0034] Specifically, the turning plate 50 has a first position and a second position arranged relative to the discharge port. The turning plate 50 can be switched from the first position to the second position under the drive of the driving part. When the turning plate 50 is in the first position, the turning plate 50 is vertically arranged to block the discharge port. When the turning plate 50 is in the second position, the turning plate 50 avoids the discharge port and is located below the screen 20. Through the above setting, when the turning plate 50 rotates and switches to the second position, the turning plate 50 is completely located below the screen 20, which can prevent the turning plate 50 from blocking the discharge of the coal gasification slag on the screen 20.

[0035] Further, when the flipping plate 50 switches to the second position, the end of the flipping plate 50 away from the screen 20 is lower than the end of the flipping plate 50 close to the screen 20. With the above arrangement, when the flipping plate 50 switches to the second position, the flipping plate 50 is in an inclined state. Through the attitude cooperation between the flipping plate 50 and the screen 20, the flipping plate 50 can play a role in guiding the coal gasification slag, facilitating the coal gasification slag to fall onto a transfer device connected to the concrete preparation system, such as a belt conveyor or a pipeline conveyor.

[0036] Specifically, when the flipping plate 50 blocks the discharge port, the screen 20 abuts against the flipping plate 50. With the above arrangement, it can prevent the coal gasification slag from falling through the gap between the screen 20 and the flipping plate 50, ensuring the screening effect of the screen 20 and preventing material waste.

[0037] Optionally, in other embodiments of the present application, the blocking member can also be arranged to cover the discharge port and is driven by a linear module or other forms of driving mechanisms to move relative to the discharge port in a linear direction to block or open the discharge port.

[0038] Specifically in the present application, a buffer assembly is further arranged between the screen 20 and the inner wall of the material box 10 to buffer the vibration of the screen 20 on the material box 10. By arranging the buffer assembly, the vibration of the screen 20 can be buffered, reducing the influence of the screen 20 on the stability of the material box 10. At the same time, it can also reduce the noise during the operation of the overall sorting device and reduce the impact on the production environment caused by the vibration of the screen 20.

[0039] In a specific embodiment of the present application, the buffer assembly includes a support block 61, a telescopic rod 62, and a buffer spring 63. Among them, the support block 61 is arranged on the side wall of the material box 10; the telescopic rod 62 is arranged between the support block 61 and the screen 20, and the telescopic direction of the telescopic rod 62 is the same as the vibration direction of the screen 20; the buffer spring 63 is sleeved on the telescopic rod 62, one end of the buffer spring 63 abuts against the screen 20, and the other end of the buffer spring 63 abuts against the support block 61 to buffer the vibration of the screen 20. With the above arrangement, the telescopic rod 62 can guide the vibration of the screen 20, and the buffer spring 63 cooperates with the telescopic rod 62 to buffer the vibration of the screen 20.

[0040] Specifically, multiple buffer assemblies can be arranged, and the screen 20 is fixed to the inner wall of the material box 10 through multiple buffer assemblies to improve the stability of the support of the screen 20 and enhance the buffering effect of the buffer assembly.

[0041] In the present application, a dust collecting component is also provided on the material box 10. During the vibration of the screen 20, the dust part in the gasification slag will be suspended in the storage chamber 11 under the action of the screen 20. As the sealing member opens the discharge port, the dust suspended in the storage chamber 11 will float in the air and even be mixed into the concrete preparation system along with the transportation mechanism, seriously affecting the production quality and production environment. By providing a dust collecting component, the dust in the storage chamber 11 can be collected to reduce dust pollution.

[0042] Specifically, the dust collection assembly includes a dust bag 71 and a fan 72. The fan 72 is disposed in the storage chamber 11. The outlet of the fan 72 is connected to the dust bag 71 to transport the dust in the storage chamber 11 to the dust bag 71. Through the above arrangement, the fan 72 can guide the dust in the storage chamber 11 into the dust bag 71 to collect the dust, facilitate centralized treatment, and reduce the impact of the dust.

[0043] Specifically, the sorting device further includes a collecting box 73, which is connected to the storage chamber 11 and is located below the screen 20. By providing the collecting box 73, the coal gasification slag screened by the screen 20 can be collected by the collecting box 73, which is convenient for subsequent landfill or centralized treatment.

[0044] According to an embodiment of the present application, a concrete preparation system is also provided, such as Figure 2 As shown, the concrete preparation system includes the above-mentioned sorting device. By applying the above-mentioned sorting device, automatic quantitative feeding can be achieved, and there is no need to set a weighing process between the sorting process and the transfer process, which simplifies the overall production steps, realizes the feeding of coal gasification slag, and improves the production efficiency of concrete preparation.

[0045] Specifically, the concrete preparation system includes a mixer 01 and a belt conveyor 02. The belt conveyor 02 is arranged between the mixer 01 and the sorting device and is arranged corresponding to the discharge port to receive the gasified slag discharged from the discharge port through the flip plate 50 and introduce the sorted gasified slag into the mixer 01.

[0046] The concrete preparation system also includes a powder silo 03, a raw material scale 04, a water pump 05, a sand and gravel silo 06, a powder silo 07 and a conveying device. The conveying device is used to convey the raw materials in the powder silo to the mixer 01, the powder silo 03, the sand and gravel silo 06 and the powder silo 07 are used to hold various raw materials, and the mixer 01 is used to mix and stir aggregates such as cement, powder, water, sand and gravel, and coal gasification slag to prepare concrete.
