Description
Technical Field
The application relates to the technical field of equipment for fertilizer production, in particular to a cyclone dust collector discharging device with no extra energy consumption and good tightness.
Background
In the production process of the compound fertilizer, a link for ventilating and drying fertilizer particles is arranged, in the link, tiny particles of the fertilizer can be brought into the atmosphere along with drying air through a pipeline to cause air pollution and product waste, so that the fertilizer particles in the drying air generally have to be throttled as much as possible for recycling, and meanwhile, the drying air finally discharged into the atmosphere is purified, so that the environment-friendly requirement is met. Here we are familiar with dust removal of fertilizer particles trapped in the drying wind. Cyclone dust removal is mainly used for removing dust above 5 microns, and collected dust is recycled.
When the cyclone dust collector is used, the dry air with fertilizer dust tangentially enters the cylindrical pipe to generate external vortex, the external vortex air sinks while rotating, and then continues to form ascending internal vortex after sinking to the bottom of the cone pipe, and finally the external vortex air goes out from the exhaust pipeline. The larger particle dust in the drying gas is thrown to the column wall due to the action of centrifugal force in the vortex motion process, and slides to the bottom of the dust remover, so that the larger particle dust is accumulated at the bottom of the dust remover.
The bottom of the cyclone dust collector is required to be provided with a discharge door device, when a certain amount of dust is collected at the bottom, the discharge door is automatically opened to discharge the dust, then the cyclone dust collector is closed to continuously collect the dust, and thus the dust is collected and discharged and continuously circularly works.
In the working process of the cyclone dust collector, the discharging door at the bottom is required to be sealed all the time, if the sealing is poor, external air flows in due to negative pressure in the cyclone dust collector, the flowing air swells dust which is settled at the bottom and is discharged out of the air outlet along with internal vortex airflow, so that the dust collection efficiency is greatly reduced, and when the air leakage rate is 5%, the purification efficiency is reduced from 90% to about 50%; when the air leakage rate reaches 15%, the purification efficiency is reduced to zero, namely the cyclone dust removal equipment fails.
The cyclone dust removal discharger usually adopts a star discharger, however, the discharger adopts a motor-driven continuous operation mode, is suitable for the condition of large discharge amount of dust per unit time, and is easy to damage in an acidic environment such as a fertilizer production workshop due to the existence of rolling bearings, motors and other metal parts in the discharger. Therefore, the cyclone dust collector used in the common fertilizer production does not adopt a star discharger, but adopts a relatively simple elastic flap valve. The valve is made of a corrosion-resistant rubber material, when dust is collected to a certain amount, the turning plate is pushed away under the action of the gravity of the dust, after the dust is discharged, the turning plate returns under the action of elastic force, and under the action of negative pressure at the bottom of the cyclone dust collector, the turning plate presses the discharge opening, so that the discharge opening is sealed.
The elastic flap valve has a simple structure, realizes opening and closing actions by utilizing gravitational potential energy of dust, elasticity of the flap and negative pressure at the bottom of the cyclone dust collector, does not need to consume extra energy, and is a good discharging device. However, this simple discharge valve also suffers from drawbacks. In the process of normally opening the turning plate for discharging, the bottom of the cyclone dust collector is in a straight-through state with the outside, and when the accumulated dust falls down, a large amount of outside air is sucked into the cyclone dust collector, namely, air leakage is caused, and part of the dust is brought back to the dust collector by the air leakage to be discharged from an exhaust port during discharging, so that the dust collection efficiency is greatly reduced; moreover, when the weather is wet, fertilizer dust at the discharge opening is in a mud lump due to moisture absorption, and has certain viscosity, and the fertilizer dust is bonded at the edge of the discharge opening and the edge of the elastic turning plate in a pile, so that the elastic turning plate valve cannot be well attached to the discharge opening, the discharge opening cannot be sealed, the dust removal efficiency is greatly reduced, the cyclone dust collector can be always in a failure state when the dust removal efficiency is serious, and therefore, in wet weather, the sticky dust on the discharge opening and the turning plate is frequently required to be manually cleaned, and the workshop cannot be attended by people. Such a discharge device has certain drawbacks.

Further, in order to prevent the outside air from being directly connected with the cyclone dust collector when the discharge opening 7 is opened, the cyclone dust collector further comprises a sealing door 16 arranged in a cone pipe at the bottom of the cyclone dust collector, wherein a through hole penetrating through the edge of one side and the edge of the other side is formed in the sealing door 16; a horizontal rotating shaft is arranged in the vertebral canal; the rotating shaft penetrates through the through hole to connect the sealing door with the vertebral canal; the lower surface of the sealing door 16 is connected with one end of a door closing spring 17, and the other end of the door closing spring 17 is connected with the inner wall of the hopper 4; the upper surface of the sealing door 16 is connected with one end of a door opening spring 18, and the other end of the door opening spring 18 is connected with the inner wall of the vertebral canal 2.

The connection between the door closing spring 17 and the lower surface of the sealing door 16 and the connection between the door opening spring 18 and the upper surface of the sealing door 16 are deviated from the position where the center of the sealing door is located, and the deviation directions are the same.
Further, the fixed cantilever assembly includes a first C-shaped cantilever 301 and a second C-shaped cantilever 302; the first C-shaped cantilever 301 and the second C-shaped cantilever 302 have one end fixedly connected to the vertebral canal 2, and the other end fixedly connected to the hopper conduit 1.

The bottom of the hopper 4 is provided with a closed inclined plane structure for facilitating the discharge of deposited materials.
The application provides a cyclone dust collector discharging device, wherein the lower end of a cone pipe part at the bottom of a cyclone dust collector is connected with a hopper through an organ type telescopic sealing sleeve, the hopper can move up and down along a hopper guide pipe, the hopper guide pipe can be in a square barrel shape which is matched with the shape of the hopper, the hopper guide pipe is rigidly connected with the cone pipe of the dust collector through a fixed suspension arm, meanwhile, the bottom of the cone pipe is also connected with the hopper through a tension spring, granular fertilizer settled by the cyclone dust collector falls to the bottom of the hopper, the hopper is sleeved by the square hopper sleeve, and leather materials with certain thickness are adhered around a discharging opening, so that the discharging opening of the hopper and the inner wall surface of the hopper guide pipe form extrusion force, and the hopper guide pipe wall closes a hopper outlet to form a discharging door structure, so that fertilizer particles are temporarily accumulated at the bottom of the hopper.
In the working process, the weight of the bottom of the hopper gradually increases along with the accumulation of fertilizer particles, and when a certain amount of fertilizer particles is reached, the hopper starts to slide downwards along the sleeve of the hopper, the discharge opening is opened, and discharging is started. After the discharging is completed, the hopper moves upwards along the sleeve of the hopper under the action of the return spring, and the discharging opening is closed.
The door structure has the advantages that the inner wall of the hopper guide pipe has a scraping action on the discharge opening, and when the hopper guide pipe works in wet weather, the chemical fertilizer mud clusters adhered to the discharge opening cannot block the closing of the discharge opening, so that the defect that the discharge opening is not tightly closed in wet weather is overcome.
When the discharging door is in operation, if the hopper slowly descends along with the increase of the accumulated ash weight and overcomes the pulling force of the return spring, when the discharging opening has a certain opening degree, the weight of the hopper and the dust is reduced, if the weight is reduced to be smaller than the pulling force of the return spring, the hopper ascends, and then the discharging opening is closed, so that the opening time of the discharging opening is too short, and the discharging cannot be thoroughly performed. As shown in figure 5, aiming at the problem, a locking device is arranged in the device, wherein a second steel ball on the wall of the hopper is clamped in an arc-shaped groove on the inner wall of a guide pipe of the hopper under the action of a second pressure spring, when the weight of fertilizer dust is accumulated to be fixed, the component force of the reaction force of the arc-shaped groove to the second steel ball in the horizontal direction is larger than the pressing force of the locking spring, the second steel ball is contracted inwards, at the moment, the pulling force of a return spring of the hopper is designed to be smaller than the weight of the hopper and the dust (when the discharge opening is fully opened, the pulling force of the return spring still is smaller than the sum of the weight of the hopper and the collected dust), so that the hopper suddenly starts to descend, the pulling force of the return spring is larger than the gravity of the hopper after discharging, and thus the hopper is lifted back under the action of the return spring, when the second steel ball moves into the arc-shaped groove on the inner wall of the guide pipe of the hopper, the hopper is clamped, and the return is realized.
The first steel ball below is used for generating a leaning force between the discharge opening and the hopper conduit so that the discharge opening is tightly closed.
In order to prevent the outside air from being in a straight-through state with the cyclone dust collector when the discharge opening is opened, a sealing door is arranged in the cyclone dust collector, when the discharge opening is closed, as shown in fig. 6, the sealing door is in an open state, and when the discharge opening is about to be opened, as shown in fig. 7, the sealing door is in a closed state, so that the outside air can not enter the cyclone dust collector due to the negative pressure effect at the bottom of the cyclone dust collector when the discharge opening is opened, and the dust collection efficiency is not reduced.
As shown in fig. 6, 7 and 8, the sealing door is controlled by the cooperation of a door opening spring, a door closing spring, a stop block and a hopper. When the hopper starts to descend until the discharge opening is about to be opened, the tensile force obtained by the elongation of the door closing spring is larger than the tensile force generated by the elongation of the door opening spring (the rigidity relation of the two springs must meet the requirement), so that the sealing door is in a closed state when the hopper is in the position. The hopper then continues to descend, at which time the sealing door cannot continue to rotate, so a stop is designed, as the hopper moves downward, the door closing spring continues to extend, the tension increases, but the sealing door is limited by the stop, so the sealing door continues to be in a closed state.
After the discharging is finished, the hopper is lifted until the discharging door is completely closed, the sealing door is always in a closed state, the closing door spring is shortened along with the continuous lifting of the hopper, the pulling force of the opening door spring is larger than that of the closing door spring, and the sealing door starts to be opened.
In a word, in order to overcome the defect of air leakage during unloading of the traditional unloading door device, the cyclone dust collector unloading device is provided with a sealing door linked with the unloading door so as to separate the unloading opening from the external atmosphere during unloading; the device with scraping action is adopted when the discharge opening and the hopper conduit relatively move, so that the closing of the discharge opening is not influenced by sticky particles generated by the wetting of chemical fertilizers. The unloading work can be carried out under the condition of no energy consumption, the unattended operation of the production workshop is realized, and the dust remover always works under the working condition of good dust removal efficiency.
