Description

Technical Field

[0001] The invention relates to the technical field of lime processing, in particular to a dust-free loading and ash discharge valve for block lime. Background Art

[0002] Lime powder is a white powdery substance with calcium carbonate as the main component. It has a wide range of applications. The most common application is in the construction industry, that is, industrial calcium carbonate. Currently, lump limestone is calcined into lump lime through a lime kiln. Part of the lump lime is directly used for molten steel refining and ironmaking. This part is called refined lime, which is uniformly referred to as lump ash in this article. The lump ash is stored in an elevated silo and loaded onto the truck through an ash discharge valve.

[0003] At present, most of the lump lime loading adopts jaw discharge valve, and the outlet is 2.8 meters away from the bottom plate of the car box. Although a dust hood is used, it has no dust absorption effect. A large amount of dust is generated when discharging the ash. This kind of dust will spread in the workshop, which is extremely harmful to the human body. Moreover, the dust particles are small. Even if the operators wear masks, they still cannot completely prevent contact with dust. With the increasing requirements of environmental protection and stricter systems, dust must be greatly reduced. Therefore, we urgently need a dust-free lump lime loading and discharging valve to solve the above problems. Summary of the invention

[0004] The purpose of the present invention is to provide a dust-free loading and ash-discharging valve for block lime, which solves the problems raised in the background technology.

[0009] A diversion box is arranged below the processing box, the diversion box is fixedly connected to the two bottom ends of the discharge pipe, the outer side of the diversion box is also fixedly connected to the processing box through a bracket, and a diversion component is arranged inside the diversion box.

[0010] Through the above technical scheme, the second driving motor is a servo motor, which drives the second driving motor on the driving block to move up and down through the first linear guide rail, and the second driving motor drives the second transmission rod to be moved, and the moving blade on the vibrator shovels the lime, and cooperates with the vibrator to increase the movement amplitude of the lime, so that the dust on the lime is lifted up, thereby reducing the dust during subsequent discharge, and the spring net rope acts to make the lime contact with the spring net rope when the lime is discharged as a whole. The spring net rope can change the movement trajectory of the lime block through elastic force, thereby lifting the dust through collision with the inner wall of the processing box or with the remaining lime blocks, thereby achieving a better dust removal effect, wherein the side of the vibrator connected to the second transmission rod will not vibrate, thereby ensuring the stability of the operation of the second driving motor connected to the second transmission rod, and the vibrator is divided into two parts, the vibration unit is connected to the moving blade, and the stabilization unit is connected to the second transmission rod.

[0011] Preferably, the diversion assembly includes a diversion plate, which is fixedly connected to the center position of the top wall of the diversion box, and the left and right sides of the diversion plate are respectively fixedly connected with diversion pipes, and the diversion pipe is fixedly connected with a valve one, and the center position of the bottom wall of the diversion box is fixedly connected with a drive motor three, the output end of the drive motor three is fixedly connected with a transmission rod three, the transmission rod three is fixedly connected with a connecting plate, the connecting plate is fixedly connected with a drive motor four, and the output end of the drive motor four is fixedly connected with a diversion barrel.

[0012] Through the above technical scheme, the transmission rod three on the driving motor three of the present application is used to drive the connecting plate to rotate along the central axis. The diverter plate is of inclined design, a partition is arranged on the diverter plate, and the number of diverter tubes on one side of the diverter plate is three. When the lime enters the diverter box through the discharge pipe two on the processing box, it flows downward through the diverter plate into the corresponding diverter tube, thereby realizing the separate processing of the lime. The connecting plate is a telescopic device with a telescopic function.

[0013] Preferably, hydraulic cylinder 1 is fixedly connected to the upper and lower sides of the diverter barrel, telescopic sleeves are fixedly connected to the upper and lower sides of the diverter barrel, and the output end of hydraulic cylinder 1 is fixedly connected to the movable end of the telescopic sleeve, valve 2 is fixedly connected to the upper and lower sides of the diverter barrel, an annular frame is fixedly connected to the inner wall of the diverter barrel at the center position, and a connecting pipe is fixedly connected to the annular frame, the upper and lower sides of the connecting pipe are fixedly connected to the inner wall of the diverter barrel, and a dust exhaust hole is opened on the connecting pipe.

[0014] Through the above technical scheme, the connecting pipe of the present application is an intermediate circular pipe with inclined upper and lower sides, and the conical surface is fixedly connected to the inner wall of the diversion barrel. Hydraulic cylinder 1 acts to drive the movable end of the telescopic sleeve to connect with valve 1 on the diversion pipe, so that the lime can be discharged through the opening of valve 2 and enter the diversion barrel. The diversion pipe acts to divert the lime and disperse the volume of the lime, so that the dust can be better handled.

[0015] Preferably, a vacuum cleaner 1 is fixedly connected to the left and right sides of the diversion box, the upper input end of the vacuum cleaner 1 extends inwardly into the diversion box, a dust exhaust pipe is also fixedly connected inside the vacuum cleaner 1, the dust exhaust pipe is interconnected with the dust suction box, a sewage valve is provided on the dust exhaust pipe, and a connecting valve is fixedly connected to the lower surface of the diversion box.

[0016] Through the above technical scheme, the connecting valve of the present application corresponds to the position of the diversion barrel. When the lime blocks in the diversion barrel are discharged after dust collection, the hydraulic cylinder drives the corresponding telescopic sleeve to move downward and dock with the connecting valve to discharge the material.

[0017] Preferably, the bottom end of the diverter box is fixedly connected to a lifting pipe, the diverter box is fixedly connected to each stage of the lifting pipe through a driving component, a buffer plate is fixedly connected inside the lifting pipe, and a contact discharge component is provided at the bottom end of the lifting pipe.

[0018] Through the above technical solution, the driving assembly of the present application is used to unfold the lifting tube. The driving assembly is usually connected to the warehouse beam. The driving assembly is usually composed of a driving motor and cables. The lifting tube in the present application has a three-stage extension, so that the lifting tube can be lowered to a reasonable discharge height.

[0020] Through the above technical solution, the air pipe of the present application is arranged in a circle on the discharge tray, and the negative pressure machine is started to form a negative pressure air field at the bottom of the discharge tray. When the third stage on the lifting pipe contacts the discharge tray and the inner wall of the bucket, the adsorption plate fits tightly with the inner wall of the bucket, thereby reducing dust overflowed during the discharge process.

[0021] Because the lifting tube needs to move upward during discharging to avoid the accumulation of lime blocks, after being attached to the inner wall of the truck bucket, the lime blocks fall downward and continue to accumulate in the lifting tube. When most of the lime blocks are accumulated in the lifting tube, the dust generated by the unloading gradually decreases. At this time, the negative pressure machine is closed, and the lifting tube is slowly raised through the driving component, so that the lime blocks are slowly moved outward. The moving speed of the lifting tube is reduced by controlling the moving speed of the lifting tube, thereby reducing the dust raised by the lime blocks due to excessive speed.

[0023] Through the above technical solution, when there is no need to move the material, the lever is flush with the bottom surface of the discharge tray and is used to move the lime blocks, and the two levers are moved alternately.

[0024] Preferably, a second vacuum cleaner is also fixedly connected to the discharge tray.

[0025] Through the above technical solution, the vacuum cleaner 2 of the present application includes a dust collection device and a dust storage bag, and the vacuum cleaner 2 is a surround design.

[0026] By adopting the above technical solution, the beneficial effects of the present invention are:

[0027] 1. The dust-free loading and ash discharge valve of the block lime performs a dust cleaning process during the falling process of the lime block through the setting of the dust treatment mechanism. By continuously moving and increasing the movement trajectory of the lime block, the dust attached to the lime block and the dust generated during the falling process are absorbed, and the falling speed of the lime block is reduced, so that the dust attached to the lime block can be effectively treated, thereby realizing the absorption of dust in the initial stage of falling, and improving the situation of large dust during the previous discharge.

[0028] 2. The dust-free loading and ash discharge valve of the block lime can divert the lime blocks through the setting of the diversion component, so that the aggregated lime blocks can be divided into lime blocks in several areas, so that the dust can be treated separately, so that the dust can be treated twice in the medium term, and the dust can be further treated, thereby realizing the treatment of the dust on the aggregated lime.

[0029] 3. The dust-free loading and discharging valve of the block lime can effectively slow down the discharging speed of the lime block by setting the contact discharging component and the shifting component, and can shift the complete discharging of the lime block, thereby reducing the movement speed of the lime block and reducing the dust raised.

The driving assembly of the present application is used to unfold the lifting pipe 7. The driving assembly is usually connected to the warehouse beam. The driving assembly is usually composed of a driving motor and cables. The lifting pipe 7 in the present application has a three-stage extension, so that the lifting pipe 7 can be lowered to a reasonable discharge height.
