Description
Technical Field
The invention relates to material conveying, in particular to mechanical equipment for automatically conveying waste cotton detection samples.
Background
In a large cotton notarization inspection laboratory, after a cotton sample is inspected, except for temporary storage or outgoing of sample reservation and sampling inspection, other samples are processed through links such as abandonment, collection, packaging, storage and the like, and finally auction processing is carried out. The cotton sample discarded after HVI (high volume cotton tester) testing is hereinafter referred to as waste cotton.
The public inspection yield of large cotton public inspection laboratories varies from 10 to 100 ten thousand tons, so that the quantity of waste cotton in each laboratory is large. At present, most of the waste cotton after the HVI machine is detected is conveyed to a packaging room in a centralized way by adopting a conveying belt for packaging.
In order to plan and design a more reasonable and more advanced cotton public inspection laboratory, a packing room is usually arranged in a relatively independent waste cotton warehouse, so that the cotton public inspection laboratory is tidy, attractive, safe and environment-friendly, the waste cotton after being packed is directly stored nearby, the middle transfer link is reduced, the labor intensity is reduced, and the safety is also improved.
The belt conveyor is called a conveying belt for short, is composed of a bracket, a transmission roller, a motor, a PLC control system and the like, and needs to occupy a certain space; the conveyer belt is an electromechanical device, needs to be maintained and repaired regularly, and the installation place of the conveyer belt must meet the space for personnel to come in and go out and approach, so the vertical shaft and the underground passage are two common technical measures. The investment of the vertical shaft and the underground passage is large, and the building cost is high. The conveyor belt directly transports the waste cotton from the HVI machine to the baler over a relatively long distance, and the conveyor belt is also relatively expensive. In addition, the conveyor belt cannot achieve absolute vertical lift (light cotton waste clumps can fall out), which increases the difficulty of fully adopting this solution.
If the pneumatic conveying system is directly used for replacing a belt conveying system, although the cost can be saved and the conveying efficiency can be improved, the constant-temperature, constant-humidity and micro-positive-pressure working environment of the HVI detection chamber can be influenced due to the negative pressure suction effect of the pneumatic conveying system, and the development of the normal HVI detection work is influenced.
Disclosure of Invention
In order to overcome the technical defects, the invention provides the waste cotton conveying transfer box which is suitable for switching from a belt conveying state to a pneumatic conveying state, so that the conveying efficiency is improved, and the cost of conveying equipment is reduced.
In order to achieve the above purpose, the invention adopts the technical scheme that: the utility model provides a transit case is carried to cotton waste, is equipped with the case lid including the box that is used for storing cotton waste, the case lid is seted up a feed inlet and is worn to be equipped with a guiding tube, and inside the guiding tube stretched into the box, the port of guiding tube was unsettled state for the bottom half.
Further, the port of the guide pipe is communicated with a material suction bell mouth.
Further, the feed inlet is connected with a trapezoidal feed hopper.
Further, a self-hanging type sealing cover is arranged at the feeding port.
Further, the inside wall of box sets up the feeding deflector, and the feeding deflector is located the below of feed inlet.
Furthermore, air supply openings are formed in the side face and the back face of the box body.
Furthermore, the air supply opening device is provided with an electric adjusting air valve.
Meanwhile, the technical scheme adopted by the invention is as follows: a waste cotton conveying transfer system comprises a conveying belt, a pneumatic conveying blast pipe and a transfer box positioned between the conveying belt and the pneumatic conveying blast pipe, wherein the transfer box is provided with a feed inlet and a guide pipe in a penetrating manner, the guide pipe extends into a box body, and a port of the guide pipe is in a suspended state relative to the bottom of the box body; the feed inlet is in butt joint with the conveying belt, and the guide pipe is communicated with the pneumatic conveying air pipe.
By implementing the technical scheme, the transfer box comprising the guide pipe can be arranged between the conveying belt and the pneumatic conveying air pipe and used as a conversion device between the conveying belt (utilizing the friction conveying principle) and the pneumatic conveying system, so that waste cotton from the conveying belt has a short conveying section with low speed and without influencing the HVI working environment, and once the waste cotton enters the pneumatic conveying air pipe under negative pressure, the waste cotton is conveyed to the packing chamber at high speed and in a long distance, the whole conveying efficiency is greatly improved, thus not only ensuring that the air environment of the HVI detection chamber with constant temperature, humidity and micro positive pressure is not pumped into negative pressure by the pneumatic conveying system, ensuring that the accurate control of temperature and humidity parameters is not influenced and avoiding that the detection work is forcibly interrupted, but also realizing the vertical lifting movement of the waste cotton so as to reduce the cost for constructing a vertical shaft and an underground passage under the state of the traditional conveying belt, the design difficulty of the overall delivery system is also reduced.
