The invention relates to a concrete mixing plant which can carry out staged dedusting in the working process and a method; the concrete mixing plant consists of a stirring mill, an aggregate temporary storage bin, a main tower composed of a powder metering device, a dust removing device and a control unit. The stirring mill is communicated with the dust removing device by a first dust transfer passage, the powder metering device is communicated with the aggregate temporary storage bin by a second dust transfer passage, the dust removing device is connected with the aggregate temporary storagebin and is communicated with the aggregate temporary storage bin by a third dust transfer passage, the third dust transfer passage is internally equipped with a ventilation door which can be opened or closed, the ventilation door can be manipulated by a door operation mechanism to shift between an open position and a closed position, and the door operation mechanism is arranged to be controlled by the control unit. The staged dedusting method is characterized in that: the dust removing device can carry out dedusting operation during the process of putting aggregate into the aggregate temporary storage bin by optionally closing or opening the ventilation door, while dedusting operation is stopped during the process of transferring the aggregate from the aggregate temporary storage bin intothe stirring mill.

The invention discloses a high-efficient thread sucking machine for preventing a thread residue from blocking a filter plate. The high-efficient thread sucking machine is used for solving the problems of bad absorbing effect and low absorbing efficiency of the existing thread sucking machine. The high-efficient thread sucking machine comprises a case, wherein a centrifugal fan driven to rotate by a driving motor is arranged in the case; the upper end of the centrifugal fan is provided with a first filter plate, and the case at the upside of the first filter plate is provided with an air inlet flue; the lower side of the case is provided with an air outlet, and the periphery of the centrifugal fan is sleeved with a first air inlet flue, and the upper end of the first air inlet flue is contacted with the first filter plate; the upper part of the first filter plate is provided with a second air inlet flue with a small upper end and a big lower end; the lower end of the second air inlet flue is corresponding to the first air inlet flue, and the upper end of the second air inlet flue is provided with an air inlet channel; a spiral flow diversion plate is arranged in the air inlet channel, and a gap is arranged between the air inlet channel and the second air inlet flue; the periphery of the second air inlet flue is provided with a collecting silo; the upper end of the collecting silo is sleeved at the periphery of the air inlet channel; a closed space is formed by the first air inlet flue, the collecting silo and the air inlet channel.

The invention discloses an air-drying device for plastic braces, which comprises a conveying unit, an air-drying unit, and a gas-liquid separation unit. The air-drying unit includes a water receiving tray and a fan connected to the bottom of the water receiving tray through an air pipe. The conveying unit includes a set The two sets of conveying rollers on the upper end of the water receiving tray, the cover plate located above the water receiving tray, the plastic stays are moved and tensioned between the two sets of conveying rollers and the cover plate, and the gas-liquid separation unit includes a A separation box with a separation chamber inside. The lower part of the separation box has a drain port and the upper part has an exhaust port. A gas-liquid separation channel is formed between the air outlet of the fan and the exhaust port. The cover plate is hingedly installed on the upper part of the water tray to ensure the wind pressure of the air inlet when the fan is working. The fan sucks away the moisture on the plastic braces in real time, and the air flow with water enters the gas-liquid separation unit from the air outlet. After separation, the gas flows from the exhaust port. Drain, the water is discharged from the drain port, the structure is simple, compact, simple and beautiful, the work is reliable, and the work efficiency is effectively improved.

The invention discloses a differential kiln capable of automatically cooling a bearing to realize dust removal. The differential kiln comprises a kiln body, a loop tower, a loop tower bearing and a high-pressure blower communicated with the kiln body, wherein the loop tower bearing comprises balls, a lower ball seat fixedly arranged and an annular upper ball seat arranged on the lower ball seat; a ball groove is arranged between the upper ball seat and the lower ball seat; the upper ball seat or lower ball seat is provided with an air inlet communicated with the ball groove; the air inlet is communicated with the high-pressure blower; and the upper ball seat is provided with an air outlet communicating the ball groove and the upper surface of the upper ball seat. In use, high-pressure air generated by the high-pressure blower is blown into the ball groove through the air inlet and then discharged into the kiln for calcining through air outlet, and the process can effectively cool the balls and the ball groove and remove dust out of the ball groove; and meanwhile, a certain air pressure is kept in the ball groove, thereby effectively preventing external dust from moving in the ball groove. Thus, in a working environment of a low rotation speed, the bearing can not seriously damaged without use of any lubricating oil, thereby ensuring that the bearing is maintenance-free.

The invention relates to the field of agricultural machinery, in particular to a self-regulating bionic fan with a variable angle, which consists of a center mounting carrier, a steering gear, bionic fan blades, a gas flow sensor and an embedded development board; the bionic Between the two points A and B on the upper half of the fan blade is the outer edge curve of the fan blade. The outer edge curve is formed by connecting a plurality of convex outer edge convex hulls (simulating the outer edge curve of the humpback whale fin) ; The inner edge curve of the fan blade is between the two points of the lower half of the bionic fan blade A', B', and the inner edge curve is formed by a plurality of (simulated humpback whale fin outer edge curves) concave inner curves. The bionic fan of the invention can imitate the swing of the fins of the whale when it is swimming, increase the air flow of the fan, and stabilize the air flow at the same time. It is suitable for the operation of the pneumatic seed meter in any environment .
