[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In order to solve the problem that in the prior art, after the waste recycling device collects the waste into the collection box, in order to reuse the recycled waste, workers need to put the waste into the melting furnace to melt it into blanks again before secondary processing, which wastes a lot of manpower, Figure 1-3 , this embodiment provides the following technical solutions:

[0022] A waste recycling device for motor housing casting, comprising a collecting bin 1, a fan 2 is arranged on the outer surface of the collecting bin 1, an air delivery pipe 3 is arranged on the fan 2, a bendable hollow pipe 4 is arranged at one end of the air delivery pipe 3 away from the fan 2, one end of the air delivery pipe 3 extends into the collecting bin 1, and further comprising an air expansion pipe 5, the air expansion pipe 5 is arranged on one end of the bendable hollow pipe 4 away from the air delivery pipe 3, a feed pipe 10 is arranged at the lower end of the collecting bin 1, a support column 11 is arranged at the lower end of the outer surface of the collecting bin 1, a fixed base 12 is arranged on the end of the support column 11 away from the collecting bin 1, a collecting trough 13 is arranged on the fixed base 12, a fixed clip 6 is arranged on the air delivery pipe 3, and a reserved bolt hole 7 is opened on the fixed clip 6;

[0023] In this embodiment, the collecting bin 1 is first placed on one side of the motor housing processing table, and then the air expansion pipe 5 is placed on the processing table or a position where waste and powder are easily accumulated. The air delivery pipe 3 is fixed to the processing table by using the fixing clip 6 on the air delivery pipe 3. The fan 2 starts to work, and the air expansion pipe 5 generates suction at the pipe opening to suck the waste into the air delivery pipe 3, and then the waste is put into the collecting bin 1 through the air delivery pipe 3. The waste falls into the collecting tank 13 arranged below along the feeding pipe 10 at the lower end of the collecting bin 1. When the collecting tank 13 is full of motor housing processing waste, the worker takes out the waste in the collecting tank 13 and puts it into the melting furnace for melting.

[0024] In this embodiment, a borax discharge pipe 9 is provided on the outer surface of the collecting bin 1, and the borax discharge pipe 9 extends into the collecting bin 1. A cavity 14 is provided in the borax discharge pipe 9, and the cavity 14 is connected with one end of the borax discharge pipe 9. A stopper 15 is provided in the borax discharge pipe 9 near one end of the collecting bin 1. The stopper 15 and the borax discharge pipe 9 are integrally arranged. A discharge hole 16 is provided on the stopper 15, and the discharge hole 16 and the stopper 15 are integrally arranged. The staff first injects borax into the borax discharge pipe 9. Because the borax particles are irregular and have a certain hardness, the borax will slide to the stopper 15 on the inner wall of the lower end of the borax discharge pipe 9 due to gravity, and be blocked by the stopper 15 to prevent the borax from being once The waste is discharged too much, and a small number of borax particles will enter the discharge hole 16. Because the discharge hole 16 is wide at the front and narrow at the back, the borax will eventually be stuck in the discharge hole 16 due to mutual extrusion and limitation. When the air duct 3 puts the waste into the collection bin 1, the waste hits the inner wall of the collection bin 1. Because the borax discharge pipe 9 is connected to the collection bin 1, the vibration is transmitted to the borax discharge pipe 9, so that the borax blocked in the discharge hole 16 will loosen and slide down a part, and fall into the collection tank 13 together with the waste. The workers take out the waste mixed with borax and put it into the furnace for melting. The addition of borax can make the surface of the re-melted and cooled blank smoother and remove impurities.

[0025] In this embodiment, a wind-blocking piece 8 is provided on the inner wall of the collecting bin 1 at a position corresponding to the air delivery pipe 3, and the wind-blocking piece 8 is welded to the inner wall of the collecting bin 1. The setting of the wind-blocking piece 8 can prevent the waste from flying out of the collecting bin 1 due to excessive wind force when the air delivery pipe 3 puts waste into the collecting bin 1. The waste will hit the wind-blocking piece 8, lose power and then fall naturally;

[0026] Working principle: first place the collection bin 1 on one side of the motor housing processing table, then place the air expansion pipe 5 on the processing table or a position where waste and powder are easily accumulated, use the fixing clip 6 on the air delivery pipe 3 to fix the air delivery pipe 3 on the processing table, the fan 2 starts to work, and the air expansion pipe 5 generates suction at the pipe opening to suck the waste into the air delivery pipe 3, and then the waste is put into the collection bin 1 through the air delivery pipe 3, and then falls along the discharge pipe 10 at the lower end of the collection bin 1 to the collection tank 13 arranged below. When the collecting tank 13 is full of waste generated by the motor housing processing, the workers take out the waste in the collecting tank 13 and put it into the melting furnace for melting. A borax discharge pipe 9 is arranged on the outer surface of the collecting bin 1. The borax discharge pipe 9 extends into the collecting bin 1. A cavity 14 is arranged in the borax discharge pipe 9. The cavity 14 is connected with one end of the borax discharge pipe 9. A stopper 15 is arranged in the borax discharge pipe 9 near one end of the collecting bin 1. The stopper 15 is integrally arranged with the borax discharge pipe 9. A discharge opening is provided on the stopper 15. The material hole 16 and the stopper 15 are integrally arranged. The staff first injects borax into the borax discharge pipe 9. Because the borax particles are irregular and have a certain hardness, the borax will slide to the stopper 15 on the inner wall of the lower end of the borax discharge pipe 9 due to gravity, and will be blocked by the stopper 15 to prevent excessive discharge of borax at one time. A small number of borax particles will enter the discharge hole 16. Because the discharge hole 16 is wide at the front and narrow at the back, the borax will eventually be stuck in the discharge hole 16 due to mutual extrusion. 6, and when the air duct 3 puts the waste into the collecting bin 1, the waste hits the inner wall of the collecting bin 1. Since the borax discharge pipe 9 is connected to the collecting bin 1, the vibration is transmitted to the borax discharge pipe 9, so that the borax blocked in the discharge hole 16 will loosen and slide down, and fall into the collecting tank 13 together with the waste. The workers take out the waste mixed with borax and put it into the furnace for melting. The addition of borax can make the surface of the re-melted and cooled blank smoother and remove impurities.
