The utility model relates to the technical field of photovoltaic glass production equipment, in particular to a dust collecting and discharging device for photovoltaic raw glass dust.
Background
In the photovoltaic glass production process, a large amount of dust is attached to the surface of the photovoltaic original piece of glass, and the dust is mainly used for avoiding the adhesion of two adjacent pieces of glass too tightly so as to facilitate the separation of the two pieces of glass. The dust is easy to lift up due to shaking of the photovoltaic original piece glass in the transportation process of the photovoltaic original piece glass, and the working environment is seriously influenced. In the prior art, a dust collecting hopper and an air extractor are arranged below a conveying belt for conveying the photovoltaic raw sheet glass, so that the raised dust is collected. However, the discharge opening of the existing dust hopper is usually controlled to be opened and closed by an electric dust discharging valve, such as a glass production flue gas dust removal system disclosed in patent CN 202823023U. Due to the limitation of the ash discharge valve structure and the consideration of the production takt, the ash discharge valve can only discharge once after reaching a preset collection value of a dust hopper or a long time interval. At this time, dust is raised again in large quantity due to the large discharge amount, and the cleaning difficulty is increased.

Description of the reference numerals: 1. a conveyor belt; 2. a screw feeder; 3. a dust hopper; 4. and a discharge port.
Detailed Description
In order to describe the technical contents, the achieved objects and effects of the present utility model in detail, the following description will be made with reference to the embodiments in conjunction with the accompanying drawings.
Referring to fig. 1 and 2, the device for collecting and discharging the dust of the photovoltaic raw sheet glass dust comprises a dust hopper 3, a screw feeder 2 and a controller, wherein the dust hopper 3 is arranged below a conveyor belt 1; the spiral feeder 2 is provided with a closed inner cavity, and a discharge port 4 and a feed port which are communicated with the inner cavity; the discharging end of the dust hopper 3 is arranged on the feeding hole; the screw feeder 2 is electrically connected with the controller.
The transporting belt 1 is used for transporting the photovoltaic raw sheet glass, and because the transporting belt 1 adopts a hollowed-out arrangement (see fig. 2), part of dust in the transporting process can fall into the dust hopper 3 arranged below the transporting belt 1 through the transporting belt 1. Of course, this passive collection is difficult to meet production requirements. Therefore, it is preferable to provide an air suction structure in the dust hopper 3, and to suck the dust, which is scattered around the conveyor belt 1 and lifted, into the dust hopper 3 by the air suction structure, so as to collect the dust. The collected dust is finally discharged through the screw feeder 2. Specifically, the screw feeder 2 is a conventional machine, namely, the auger is installed in a sealed cavity (namely, the inner cavity), and is driven to rotate by a motor, so that dust in the cavity is driven to move in the cavity, and finally, the dust moves to the position of the discharge hole 4 and is discharged outside through the discharge hole 4, namely, ash discharging is realized.
Although continuous ash discharge can be achieved by continuously turning on the screw feeder 2, this process is power-consuming and has low yields. Therefore, the screw feeder 2 is preferably connected with a controller, and the controller controls the start and stop of the screw feeder 2 to reduce the continuous start time and start frequency of the screw feeder 2, thereby reducing the energy consumption of the screw feeder 2. The timing of the opening of the screw feeder 2 may be based on time, for example, the timing of opening by using a controller, or may be based on the collection amount of dust, that is, when the dust in the dust hopper 3 reaches a certain height/weight, the controller opens the screw feeder 2 to perform the dust discharging process. The detection of the dust height or weight in the dust hopper 3 can be realized based on a corresponding detector, and is of an existing general structure, and a detailed description is omitted herein.
The controller can control the on-off of the screw feeder 2 in the conventional control mode, such as by using a power supply program-controlled switch.
Preferably, the controller is electrically connected with the air draft structure, namely, the controller is used for controlling the opening and closing of the air draft structure or controlling the power adjustment of the air draft structure so as to adapt to the requirements of different working conditions. Of course, such automation is not necessary, and the suction structure may be independently controlled. The exhaust structure is the existing general structure, such as the combination of the air extractor, the exhaust tube and the dust cover.
In one embodiment, the outlet 4 is arranged downward, i.e. toward the bottom surface, and the installation height of the outlet 4 is 0.5-1 m. Through the setting of this kind of mounting height, when being convenient for the collecting box to put into discharge gate 4 below, also can effectively reduce the degree of being raised again when the dust ejection of compact.
In one embodiment, the plurality of feed inlets are arranged at intervals along the forming direction of the inner cavity.
In one embodiment, the conveyor belt 1 is provided with a dust sweeping structure, which contacts at least one surface of the photovoltaic raw sheet glass carried on the conveyor belt 1 and lifts dust attached to the surface. In an alternative embodiment, the dust sweeping structure is a hair roller mounted above the conveyor belt 1.

the discharging end of the dust hopper 3 is arranged on the feeding hole;
the spiral feeder 2 is electrically connected with the controller;
the number of the feeding holes is multiple, and the feeding holes are arranged at intervals along the forming direction of the inner cavity;

the discharge hole 4 is arranged downwards, and the installation height of the discharge hole 4 is 0.5-1 m;
the dust sweeping structure is arranged on the conveyor belt 1, and is in contact with at least one surface of the photovoltaic raw sheet glass borne on the conveyor belt 1, so that dust attached to the surface is lifted.
Specifically, the air draft structure works to suck dust raised from the surface of the photovoltaic raw sheet glass in the air into the dust hopper 3. The controller controls the spiral feeder 2 to work at certain time intervals, and sends dust to the discharge hole 4 of the spiral feeder and discharges the dust through the discharge hole 4, so that the timing dust discharging is realized.
