Description

TECHNICAL FIELD

[0001] The utility model relates to conveying mechanism technical field, especially a novel solid waste conveying equipment. BACKGROUND

[0002] Solid waste is the abbreviation of solid waste, which refers to the garbage generated in production, life and other activities, including urban domestic waste, industrial waste residue, agricultural waste, construction waste and so on. In the prior art, the treatment of solid waste is generally based on the type of garbage and the actual production needs, including physical treatment (changing the physical form of waste by concentration, crushing, sorting and compaction, without destroying its chemical composition), chemical treatment (destroying harmful components or recycling resources by oxidation, reduction and neutralization), biological treatment (decomposing organic matter by microorganisms to achieve harmlessness or resource utilization), thermal treatment (reducing and harmless by high temperature treatment), landfill (urban garbage landfill), recycling (classifying and recycling metal, plastic and other recyclable resources) and so on. No matter which kind of treatment, it often involves the use of electric belt conveyor to transfer solid waste from one area to another (such as conveying the garbage in solid waste yard to the crusher by electric belt conveyor).

As can be seen from the above, although the compared patent realizes the technical effect of the invention, it is limited by structure and function, and like other garbage conveying equipment in the field, it still has the following technical defects. (1): Generally, the existing garbage conveying equipment can only absorb the metal steel waste in the garbage by magnet, and cannot actively prompt the staff after absorbing a certain amount of magnet at the lower end of the magnet. In this way, when the absorbed metal is too much, it will have a certain impact on the normal conveying of garbage (such as a certain position absorbing too much metal, the magnet will weaken the magnetism due to the blockage of the absorbed metal, which cannot normally absorb the subsequent entering metal on the conveying belt, causing the metal to enter the internal of the crusher, resulting in damage to the crusher, etc.). (2): It does not have the function of detecting metal and prompting the staff to turn off the power of the conveyor. In this way, even if a metal detector is used to detect the presence of metal in the garbage, when the staff is not on site due to various reasons or other sound interference, the metal (especially non-magnetic copper, aluminum and other metal waste) will still enter the next process, causing unpredictable consequences.

[0020] Figure 1 、 2, 3, 4, 5, the rack plate 6 of the electric belt conveyor body is made of non-metallic material (such as engineering plastic, wood material, etc.), which prevents the abnormal operation of the metal detection module A.

The detection head of the photoelectric switch A2 is located on the front side, the detection heads of the five metal detection modules A are located on the lower side, and the lower side of the photoelectric switch A2 and the lower side of the detection head in front of the five metal detection modules A are in a plane. The lower end of the polygonal rotating scraper 2 is spaced from the upper part of the ring-shaped conveying belt 62 of the electric belt conveyor, and the height of the lower end of the polygonal rotating scraper 62 is lower than the heights of the lower ends of the photoelectric switch A2, the magnet 511 and the metal detection module A. The prompt circuit includes a resistor R1, a transistor T1 and an audible and visual alarm B1 connected by a circuit board, the negative power input end of the audible and visual alarm B1 is connected with the collector of the transistor T1, and one end of the resistor R1 is connected with the base of the transistor T1. The control circuit includes a resistor R, a transistor T, relays K1 and K2 and an audible and visual alarm B connected by a circuit board, the normally open contact end of the first relay K1 is connected with the positive power input end of the audible and visual alarm B and the positive power input end of the second relay K2, one end of the resistor R is connected with the base of the transistor T, the collector of the transistor T is connected with the negative power input end of the first relay K1, the positive power input end of the first relay K1 and the control power input end are connected, and the emitter of the transistor T is connected with the negative power input end of the second relay K2 and the negative power input end of the audible and visual alarm B.

[0021] Figure 1 、 2 , 3, 4, 5, the power input ends 1 and 2 of the power module A1, the input end of the motor speed reduction device M2 and the relay K2 control power input end of the control circuit are connected in series with the two poles of the AC 220V power supply through a power switch S1; the power output ends 3 and 4 of the power module A1, the power input ends 1 and 2 of the photoelectric switch A2, the power input ends 1 and 2 of the five sets of metal detection modules A, the positive power input end of the audible and visual alarm B1 of the prompt circuit and the emitter of the transistor T1, and the positive power input end of the relay K1 of the control circuit are respectively connected through wires.

[0022] Figure 1 、 2, 3, 4, 5, the new type is based on the electric belt conveyor body M, using the electric belt conveyor body M to transfer solid waste from one area to another area (such as conveying the garbage in the solid waste yard to the crusher by the electric belt conveyor), the above is the existing mature, therefore the structure and working principle of the electric belt conveyor body M are not described. After turning on the total power switch S1, the power module A1 is powered on, the 220V (380V power supply is also used, and the motor working voltage of the corresponding electric belt conveyor body M is also 380V) power supply will control the power input end and the normally closed contact end to enter the power input end of the motor of the electric belt conveyor body M through the relay K2, and the electric belt conveyor body M works normally to convey the solid waste on the conveying belt from left to right from the previous process to the next production process. After the motor speed reduction device M1 is powered on, its rotating shaft drives the scraper 2 to rotate counterclockwise, which flattens the upper part of the solid waste on the conveying belt, which is beneficial to subsequent metal adsorption processing operations. After the solid waste is output to the lower end of the magnet 511, the magnet 511 will adsorb the magnetic materials such as steel materials in the solid waste. When the middle position of the longitudinal distribution of the magnet does not adsorb the steel material solid waste, the probe head of the photoelectric switch A2 has no obstacle in front of it, so that the 3-pin of the photoelectric switch A2 has no output, and the sound and light alarm B1 cannot be powered on to sound, when the middle position of the longitudinal distribution of the magnet adsorbs the steel material solid waste, the probe head of the photoelectric switch A2 is blocked by the obstacle in front of it, the 3-pin outputs high level, and the power input end of the sound and light alarm B1 is connected through the resistor R1, the triode T1, and the sound and light alarm B1, the sound and light alarm B1 is powered on to sound, prompting the staff to timely process the steel metal solid waste adsorbed at the lower end of the magnet (the staff raises the hand, the handle 513, and the movable plate 512 moves backward along the hinge point, so that the steel material waste adsorbed under the magnet 511 can be taken out), which reduces the probability that the magnet cannot normally adsorb the subsequent metal waste on the conveying belt due to the adsorption of metal waste without timely cleaning (when the middle of the magnet does not adsorb the solid waste, the two sides still have the space to adsorb the solid waste, so the alarm B1 does not sound temporarily, and multiple sets of photoelectric switches and resistors R1 can be installed at the left or right of the lower end of the magnet, which can alarm when the magnet adsorbs the steel material solid waste; if there is a lot of steel material waste in the solid waste, the staff can also take out the waste after hearing the alarm sound for a certain period of time).

[0023] Figure 1 、 2When there is no metal waste (such as copper, aluminum, etc.) except steel material in the solid waste, the probe head of the five metal detection modules A cannot detect metal, and the 3-pin does not output a high level, so the relay K1, K2 and the audible and light alarm B will not be powered on and work. When there is metal waste except steel material in the solid waste, the probe head of any one or more of the five metal detection modules A detects metal, and the 3-pin outputs a high level. The high resistance R reduces the voltage and limits the current into the base of the transistor T, the transistor T is turned on, the collector outputs a high level into the relay K1 negative power input terminal, the relay K1 is powered on and attracts the control power input terminal and the normally open contact terminal to close, then the relay K2 and the audible and light alarm B are powered on, the audible and light alarm B is powered on and emits sound to prompt the staff that there is non-steel material metal waste in the solid waste and to handle it in time. The relay K2 is powered on and attracts the control power input terminal and the normally closed contact terminal to open circuit, so the electric belt conveyor body M will lose power and stop working. This can facilitate the staff to clean the non-steel material metal waste in the solid waste, prevent the equipment from not stopping, and prevent the metal waste from entering the next production equipment, causing the next production equipment to work abnormally or be damaged. The first set of metal processing mechanism adopted by the new type can avoid unnecessary stop of the electric belt conveyor body M when there is mainly steel material waste in the garbage, and can ensure the production efficiency as much as possible.
