Description

Technical Field

[0001] The utility model relates to the field of crushing, in particular to a collecting device of a foam crusher. Background Art

[0002] The collection device of the foam crusher is one of its key components. It is mainly used to collect the foam fragments after the crushing process. This device is usually designed to be both efficient and easy to clean, so that it can effectively collect and store the foam fragments while reducing the flying of dust and debris.

[0003] In the prior art, an exhaust fan is arranged inside a straight pipe to absorb the foam material in the crushing chamber of the grinder into the pipe and discharge it. However, when the exhaust fan in the straight pipe sucks the foam material, part of the foam material will be absorbed and adhered to the surface of the exhaust fan due to static electricity, resulting in a decrease in the adsorption efficiency of the exhaust fan. At the same time, the exhaust fan inside the pipe is difficult to clean and is difficult to maintain manually. Utility Model Content

[0004] The purpose of the utility model is to solve any one of the problems in the above-mentioned technologies, thereby providing a collecting device for a foam crusher.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a collecting device of a foam crusher, including a frame welded with L-shaped angle irons and a crushing bin with two crushing rollers installed above the frame, a motor fixed on the frame for providing power is arranged on one side of the crushing bin, a feeding hopper is arranged above the crushing bin, a material collecting device is arranged below the frame, the material collecting hopper of the material collecting device is connected to the bottom of the crushing bin, and an air inlet branch pipe is arranged on the opposite side of the discharge port below the material collecting device.

[0006] Furthermore, the top of the collecting device is a funnel-shaped collecting hopper, the bottom of the collecting hopper is a material guide pipe with a 110° angle, the end of the material guide pipe is a discharge port, and a horizontally fixed air inlet branch pipe is arranged on the side wall of the material guide pipe opposite to the discharge port, and the air inlet branch pipe is connected to the material guide pipe.

[0007] Furthermore, an exhaust fan is fixedly arranged in the air inlet branch pipe of the material collecting device to suck the external air into the material guiding pipe of the material collecting device at a high speed and blow it out to the material discharging port.

[0008] Furthermore, a driving gear set is sleeved on one side of the crushing roller, and the driven gear and the power gear of the driving gear set are respectively fixedly connected to the two crushing rollers, and the power gear of the driving gear set is fixedly connected to the output shaft of the motor for transmission.

[0009] The beneficial effects of the utility model are as follows: an air inlet branch pipe fixed in a horizontal position is arranged on the side wall of the guide pipe opposite to the material discharge port of the collecting device, and the exhaust fan sucks external air at high speed into the material guide pipe of the collecting device and blows it out to the material discharge port. The air flow rate in the material discharge port area is large and the static pressure is low. The gas sprayed toward the material discharge port at high speed generates negative pressure suction on the material receiving hopper area of ​​the collecting device, effectively sucking the crushed foam material in the crushing bin into the collecting device for collection. At the same time, the exhaust fan is not located in the material guide pipe of the foam material, which avoids the electrostatic adsorption of the foam material on the surface of the exhaust fan. At the same time, the collecting device provides negative pressure suction to the upper area, which avoids the escape of the foam from the opening of the feed hopper when it is crushed.

DETAILED DESCRIPTION

[0014] Please refer to Figures 1 to 3 ;

[0015] The present embodiment provides a collecting device for a foam crusher, including a frame 5 welded with L-shaped angle irons and a crushing bin with two crushing rollers 3 installed above the frame, a motor 2 fixed on the frame 5 for providing power is arranged on one side of the crushing bin, a feed hopper 1 is arranged above the crushing bin, a material collecting device 6 is arranged below the frame 5, a material receiving hopper 61 of the material collecting device 6 is connected to the bottom of the crushing bin, and an air inlet branch pipe 62 is arranged on the opposite side of the discharge port 63 below the material collecting device 6.

[0016] Preferably, the top of the collecting device 6 is a funnel-shaped receiving hopper 61, the bottom of the receiving hopper 61 is a material guide pipe with a 110° angle, the end of the material guide pipe is a discharge port 63, and a horizontally fixed air inlet branch pipe 62 is arranged opposite to the side wall of the material guide pipe at the discharge port 63, and the air inlet branch pipe 62 is connected to the material guide pipe.

[0017] In a specific embodiment, when the exhaust fan 7 is started, external air is sucked into the material guide pipe of the material collecting device 6 at high speed and blown out to the discharge port 63. The air flow rate in the area of ​​the discharge port 63 is high and the static pressure is low. The gas sprayed toward the discharge port 63 at high speed generates negative pressure suction on the area of ​​the receiving hopper 61 of the material collecting device 6.

[0018] Preferably, an exhaust fan 7 is fixedly installed in the air inlet branch pipe 62 of the material collecting device 6 to suck the external air into the material guide pipe of the material collecting device 6 at a high speed and blow it out to the discharge port 63.

[0019] In a specific embodiment, when the exhaust fan 7 is started, the air inlet branch pipe 62 provides high-speed air to the material guide pipe of the material collecting device 6. The foam material adsorbed by negative pressure in the receiving hopper 61 above the material collecting device 6 will not enter the air inlet branch pipe 62 due to the strong wind pressure of the air inlet branch pipe 62, but will be directly blown out from the discharge port 63 of the material guide pipe, thereby avoiding the occurrence of electrostatic adsorption of the foam material on the surface of the exhaust fan 7.

[0020] Preferably, a driving gear set 4 is sleeved on one side of the crushing roller 3, and the driven gear and the power gear of the driving gear set 4 are respectively fixedly connected to two crushing rollers 3, and the power gear of the driving gear set 4 is fixedly connected to the output shaft of the motor 2 for transmission.

[0021] When the utility model is used, the motor 2 and the exhaust fan 7 are started, and the motor 2 drives the crushing roller 3 to rotate and crush by driving the gear set 4. The exhaust fan 7 sucks the external air at high speed into the guide pipe of the collecting device 6 and blows it out to the discharge port 63. The receiving hopper 61 area of ​​the collecting device 6 generates negative pressure suction, and the foam material to be crushed is put into the feed hopper 1 for crushing. The negative pressure suction of the collecting device 6 prevents the foam from escaping from the opening of the feed hopper 1 when it is crushed, and the crushed foam material is blown out from the discharge port 63 for collection.

[0022] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
