[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-3 This utility model provides a technical solution: a coffee bean pneumatic conveying device with impurity separation, including a first pipe 1, one end of the first pipe 1 is fixed and connected to a second pipe 11, the top end of the second pipe 11 is fixed and connected to a cylinder 2, the bottom of the cylinder 2 is fixed and connected to a waste pipe 21, the top of the inner wall of the waste pipe 21 is fixedly connected to a filter screen 22, the top of the waste pipe 21 is fixed and connected to a discharge pipe 23, and the filter screen 22 is located below the top opening of the discharge pipe 23; coffee beans enter the second pipe 11 through the first pipe 1, and then enter the cylinder 2 through the second pipe 11. After entering the cylinder 2, the coffee beans rotate along the side wall of the cylinder 2, thereby completing the separation of light impurities from the coffee beans. The coffee beans fall onto the filter screen 22 due to gravity, and the filter screen 22 separates the coffee beans from the remaining impurities. The screened coffee beans are moved to a designated location through the discharge pipe 23, and the impurities are discharged through the waste pipe 21.

[0027] The top and bottom of the inner wall of the first pipe 1 are fixedly connected to a fixing plate 3. The two fixing plates 3 are symmetrically arranged and the fixing plates 3 are inclined towards the second pipe 11. The setting of the fixing plate 3 increases the wind speed of the main airflow in its vicinity. The heavier impurities after passing through the fixing plate 3 are captured by the low-pressure zone, thereby completing the separation of the heavier impurities from the coffee beans.

[0028] Example 2:

[0029] Please see Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The filter screen 22 is set at an angle, and the side of the filter screen 22 closer to the discharge pipe 23 is lower. The filter screen 22 sieves the coffee beans. Due to the angled setting of the filter screen 22, it is convenient to transport the sieved coffee beans to the discharge pipe 23.

[0030] The bottom of the first pipe 1 is fixed and connected to the discharge pipe 31. The discharge pipe 31 is located between the fixed plate 3 and the second pipe 11. The top of the discharge pipe 31 is arc-shaped, and a manual valve 32 is installed on the discharge pipe 31. The top of the discharge pipe 31 is arc-shaped, and heavier impurities fall into the discharge pipe 31 along the arc. The manual valve 32 helps to open and close the discharge pipe 31.

[0031] The top of the first pipe 1 is fixed and connected to a feeding pipe 4. A rotating shaft 41 is rotatably installed inside the feeding pipe 4. A rotating roller 42 is fixedly connected to the outer periphery of the rotating shaft 41. Multiple blades 43 are evenly fixedly connected to the outer periphery of the rotating roller 42 in a ring shape. The blades 43 are in contact with the inner wall of the feeding pipe 4. A motor 44 is fixedly connected to the outer wall of the feeding pipe 4. The end of the rotating shaft 41 passes through the feeding pipe 4 and is fixedly connected to the rotating shaft of the motor 44. When the motor 44 is turned on, the motor 44 rotates and drives the rotating shaft 41 to rotate. The rotating shaft 41 rotates and drives the rotating roller 42 to rotate. The rotating roller 42 rotates and drives the blades 43 to rotate. Coffee beans and impurities enter the inside of the feeding pipe 4 through the through hole 46. During the rotation of the blades 43, the coffee beans are evenly transported into the first pipe 1.

[0032] A feeding shell 45 is fixedly connected to the top of the feeding tube 4. The feeding shell 45 is higher than the middle point on all sides. A through hole 46 is opened in the middle of the feeding shell 45, which is connected to the feeding tube 4. The feeding shell 45 helps to store coffee beans. The coffee beans move along the slope to the feeding shell 45 and enter the feeding tube 4 through the feeding shell 45.

[0033] A fan 5 is installed at the end of the first pipe 1 away from the second pipe 11. The air outlet of the fan 5 is fixed and connected to the first pipe 1. The fan 5 delivers air into the first pipe 1, and the air delivers coffee beans through the second pipe 11.

[0034] In use, coffee beans are placed in the feeding shell 45, and the blower 5 is turned on. The blower 5 delivers air into the first pipe 1. At the same time, the motor 44 is turned on, and the rotation of the motor 44 drives the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 drives the rotating roller 42 to rotate, and the rotation of the rotating roller 42 drives the blades 43 to rotate. The coffee beans enter the feeding pipe 4 through the through hole 46. During the rotation of the blades 43, the coffee beans are evenly delivered into the first pipe 1. The air blows the coffee beans into the first pipe 1, and the coffee beans move along the first pipe 1 to the second pipe 11. When they reach the position of the fixed plate 3, the local main airflow speed increases, and the local speed increase forms a "speed difference grading" effect. When the coffee beans and the heavier impurities inside move to the fixed plate 3 and the feeding pipe 31, the heavier impurities are captured by the low-pressure area and fall into the area around the top of the feeding pipe 31. Since the area around the top of the feeding pipe 31 is arc-shaped, the heavier impurities fall into the feeding pipe 31 along the arc. After a period of time, the user... When the manual valve 32 is opened, heavier impurities are discharged from the feed pipe 31. The coffee beans continue to move along the first pipe 1 to the second pipe 11 and enter the cylinder 2. Since the second pipe 11 is located on one side of the cylinder 2, the coffee beans rotate along the side wall of the cylinder 2, thus completing the separation of light impurities from the coffee beans. The coffee beans fall onto the filter screen 22 due to gravity, and the filter screen 22 separates the coffee beans from the remaining impurities. The filtered coffee beans are transported to the designated location along the discharge pipe 23, and the filtered impurities are discharged from the waste pipe 21. Some lighter impurities are discharged with the gas from the exhaust pipe at the top of the cylinder 2. In this utility model, the fixed plate 3 achieves the separation of heavier impurities from coffee beans through "speed difference grading". The filter screen 22 further separates coffee beans from impurities. Lighter impurities in the coffee beans are discharged from the exhaust port of the cylinder 2. Through the cooperation of the components, multi-stage separation of impurities is achieved, and the impurity separation effect is good, which provides convenience for subsequent production and use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
