Each link has strict operating requirements and standards to ensure the quality and safety of milk powder; and the screening machine is a very common mechanical equipment in the milk powder processing process. Its main function is to screen out large particles, impurities, lumps and other parts that do not meet the requirements in the milk powder to ensure the quality and taste of the milk powder.

[0003] During the processing of milk powder, when a screening machine is needed to assist, the raw materials are first introduced into the screening machine body through the feed pipe, and then the raw materials are screened through the filter screen to block the impurities in the raw materials, and then the screened raw materials are exported from the screening machine body through the discharge pipe to the next production process; but during the use of the screening machine, as the use time increases, large particles of impurities in the raw materials are easy to adhere to the filter screen, which will cause the filter screen to become blocked, and then affect the filtering and separation effect of the filter screen on impurities, thereby affecting the use of the screening machine. Utility Model Content

[0004] The purpose of the utility model is to provide a screening machine with a separation function to solve the problems raised by the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a screening machine with a separation function, comprising a screening machine body, a feed pipe and a discharge pipe, wherein the feed pipes are docked on both sides of the top of the screening machine body, and the discharge pipe is docked on one side of the bottom end of the screening machine body, and a filter screen plate is rotatably connected to the middle of the inner wall of the screening machine body, and the bottom end of the inner wall of the screening machine body is rotatably connected to the filter screen plate through a limit seat, one side of the bottom end of the filter screen plate is docked with a spring A, one side of the bottom end of the filter screen plate is docked with a spring B, a fixed seat is welded to the middle of the bottom end of the screening machine body, and an electric push column is embedded and installed inside the fixed seat.

[0009] Preferably, the top end of the guide seat B is rotatably connected to a transmission rod B, the top end of the transmission rod B is rotatably connected to a lifting rod B, and the outer wall of the lifting rod B is slidably connected to a sliding seat.

[0010] Preferably, an auxiliary mechanism is provided on the outer wall of the feed pipe, and the auxiliary mechanism includes a support platform, a drive motor, a rotating column, a stirring rod, an electric push rod and a blocking seat, and a support platform is docked at the middle of the top end of the screening machine body.

[0011] Preferably, a driving motor is installed on the top of the support platform, and a rotating column is connected to the output end of the driving motor, and a stirring rod is sleeved on the outer wall of the rotating column.

[0012] Preferably, an electric push rod is docked at the middle of the support platform, and a blocking seat is docked at the output end of the electric push rod.

[0013] Compared with the prior art, the beneficial effect of the utility model is that when the screening machine with separation function is used, the electric push column is started to extend or contract, thereby causing the filter screen plate or the filter mesh plate to collide repeatedly with the screening machine body, and then the impurities that cause the filter screen plate and the filter mesh plate to be blocked are shaken off, and the filter screen plate and the filter mesh plate are prevented from being blocked and affecting the effect of separating impurities, thereby facilitating the separation of impurities and preventing clogging. The incoming raw materials are broken up by the auxiliary mechanism to prevent large-volume lumps in the raw materials, and then the working pressure of the filter screen plate and the filter mesh plate is reduced, thereby facilitating the breaking up of the raw materials when the screening machine is in use.

[0014] 1. During the processing of milk powder, when the screening machine is needed for assistance, the milk powder is first filtered through the filter screen plate and the filter mesh plate, and then the blocked impurities are guided out of the screening machine body through the guide cavity, thereby completing the separation of the milk powder, and then the electric push column is started to extend or contract. At this time, the angle between the transmission rod A and the guide seat A changes, and the angle between the transmission rod B and the lifting rod B changes, which causes the filter screen plate or the filter mesh plate to rotate along the screening machine body. After that, the elastic force generated by the reset of the spring A or the spring B causes the filter screen plate or the filter mesh plate to collide with the screening machine body repeatedly, thereby shaking off the impurities that cause the filter screen plate and the filter mesh plate to be blocked, preventing the filter screen plate and the filter mesh plate from being blocked and affecting the effect of separating impurities, thereby facilitating the separation of impurities and preventing blockage when the screening machine is used;

[0015] 2. During the processing of milk powder, when a screening machine is needed to assist, first start the drive motor to drive the rotating column to rotate, and then the rotating column drives the stirring rod to rotate together. Then, as the stirring rod rotates at high speed, the incoming raw materials are broken up to prevent large-volume lumps in the raw materials, and then reduce the working pressure of the filter screen plate and the filter mesh plate, so that when the screening machine is used, it is easier to break up the raw materials.

DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-Figure 7 The utility model provides a technical solution: a screening machine with a separation function, including a screening machine body 1, a feed pipe 2 and a discharge pipe 3, the feed pipes 2 are connected to both sides of the top of the screening machine body 1, and the discharge pipe 3 is connected to one side of the bottom of the screening machine body 1, and a filter screen plate 4 is rotatably connected to the middle of the inner wall of the screening machine body 1, and a filter screen plate 5 is rotatably connected to the bottom of the inner wall of the screening machine body 1 through a limit seat, a spring A6 is connected to one side of the bottom of the filter screen plate 4, and a spring B7 is connected to one side of the bottom of the filter screen plate 5, a fixed seat 8 is welded to the middle of the bottom end of the screening machine body 1, and an electric push column 9 is embedded and installed inside the fixed seat 8; the output end of the electric push column 9 is connected to a guide seat A10, and the top of the guide seat A10 is rotatably connected to a transmission Rod A11; the top of the transmission rod A11 is rotatably connected to the lifting rod A12, and the outer wall of the lifting rod A12 is slidably connected to the slide rail 13, and the outer wall of the slide rail 13 is welded to the screening machine body 1; a transmission plate 14 is welded to the bottom end of the outer wall of the guide seat A10, and the side of the transmission plate 14 away from the guide seat A10 is docked with the guide seat B15; the top of the guide seat B15 is rotatably connected to the transmission rod B16, and the top of the transmission rod B16 is rotatably connected to the lifting rod B17, and the outer wall of the lifting rod B17 is slidably connected to the slide seat; the bottom ends of the springs A6 and B7 are fixed to the inner wall of the screening machine body 1, the transmission plate 14 is slidably connected to the fixed seat 8, and the outer wall of the screening machine body 1 is provided with a lead-out cavity corresponding to the filter screen plate 4 and the filter mesh plate 5.

[0027] In specific implementation, during the processing of milk powder, when the screening machine is needed to assist, the milk powder is first filtered through the sieve holes on the filter screen plate 4 to block the large-volume impurities in the milk powder, and then the milk powder is filtered again through the filter screen plate 5 to filter and separate the large-particle impurities in the milk powder, and then the blocked large-volume impurities and large-particle impurities are guided out of the screening machine body 1 through the guide cavity, thereby completing the separation of the milk powder;

[0028] As the use time increases, when the filter screen plate 4 and the filter mesh plate 5 are blocked by debris, the electric push column 9 on the fixed seat 8 is first started, and then the electric push column 9 is contracted to drive the guide seat A10 to move toward the fixed seat 8. Because the bottom end of the guide seat A10 is welded to the transmission plate 14, the guide seat A10 moves with the transmission plate 14, and then the transmission plate 14 drives the guide seat B15 to move away from the fixed seat 8.

[0029] Since the guide seat A10 and the transmission rod A11 are rotatably connected, the guide seat A10 moves to rotate the transmission rod A11. At this time, the angle between the transmission rod A11 and the guide seat A10 changes, thereby generating an upward thrust on the lifting rod A12, so that the lifting rod A12 moves upward along the slide rail 13 until the lifting rod A12 moves upward to push the filter screen plate 4, so that the filter screen plate 4 rotates along the screening machine body 1. Since the bottom end is connected to the spring A6, the filter screen plate 4 rotates, causing the spring A6 to deform.

[0030] Then the electric push column 9 is started to extend. The extension of the electric push column 9 causes the guide seat A10 to move away from the fixed seat 8, and the guide seat B15 to move toward the fixed seat 8. At this time, the angle between the transmission rod B16 and the lifting rod B17 changes, and then the lifting rod B17 moves upward to push the filter screen 5, causing the filter screen 5 to rotate along the screening machine body 1, thereby causing the spring B7 to deform. Afterwards, when the electric push column 9 extends or contracts, the spring A6 or the spring B7 will reset to generate elastic force;

[0031] This will cause the filter screen plate 4 or the filter mesh plate 5 to collide repeatedly with the screening machine body 1, and then the impurities that cause the filter screen plate 4 and the filter mesh plate 5 to be blocked will be shaken off, thereby automatically cleaning the filter screen plate 4 or the filter mesh plate 5, preventing the filter screen plate 4 and the filter mesh plate 5 from being blocked and affecting the effect of separating impurities, thereby facilitating the separation of impurities and preventing blockage when the screening machine is in use.

[0032] See also Figure 1 , Figure 2 , Figure 4 and Figure 8 It can be seen that an auxiliary mechanism 18 is provided on the outer wall of the feed pipe 2, and the auxiliary mechanism 18 includes a support platform 1801, a drive motor 1802, a rotating column 1803, a stirring rod 1804, an electric push rod 1805 and a blocking seat 1806, and the support platform 1801 is docked in the middle of the top of the screening machine body 1; a drive motor 1802 is installed on the top of the support platform 1801, and the output end of the drive motor 1802 is docked with the rotating column 1803, and the outer wall of the rotating column 1803 is sleeved with the stirring rod 1804; the electric push rod 1805 is docked in the middle of the support platform 1801, and the output end of the electric push rod 1805 is docked with the blocking seat 1806; the support platform 1801 and the electric push rod 1805 are fixedly connected, and the stirring rods 1804 are evenly spaced on the rotating column 1803.

[0033] During specific implementation, during the processing of milk powder, when the screening machine is needed to assist, in order to reduce the working pressure of the filter screen plate 4 and the filter mesh plate 5, when it is necessary to break up the raw materials entering the inside of the screening machine body 1, first start the driving motor 1802 on the support platform 1801. Since the output end of the driving motor 1802 is connected to the rotating column 1803, the driving motor 1802 starts to drive the rotating column 1803 to rotate, and since the outer wall of the rotating column 1803 is connected to the stirring rod 1804, the rotation of the rotating column 1803 drives the stirring rod 1804 to rotate together, and then with the high-speed rotation of the stirring rod 1804, the incoming raw materials are broken up to prevent large-volume lumps in the raw materials, thereby reducing the working pressure of the filter screen plate 4 and the filter mesh plate 5, thereby facilitating the breaking up of the raw materials when the screening machine is used;

[0034] And with the increase of usage time, when the screening machine body 1 fails and the rotation of the stirring rod 1804 needs to be stopped quickly, the electric push rod 1805 is started first. Because the output end of the electric push rod 1805 is connected to the blocking seat 1806, the electric push rod 1805 extends and drives the blocking seat 1806 to move until the blocking seat 1806 is in contact with the rotating column 1803. At this time, the rotating column 1803 and the blocking seat 1806 are violently rubbed, and the rotation speed of the rotating column 1803 is quickly reduced. Not only the stirring rod 1804 is stopped by turning off the drive motor 1802, but also the rotation of the rotating column 1803 is quickly stopped when the screening machine body 1 fails to prevent further losses.

[0035] To sum up, when this screening machine with a separation function is used, the raw materials are first introduced into the screening machine body 1 through the feed pipe 2, and then the raw materials are screened through the filter screen plate 5 to block the impurities in the raw materials, and then the screened raw materials are exported from the screening machine body 1 through the discharge pipe 3, and then reach the next production process. This is the prior art and will not be elaborated on here. By starting the electric push column 9 to extend or contract, the filter screen plate 4 or the filter screen plate 5 will repeatedly collide with the screening machine body 1, and then the impurities that cause the filter screen plate 4 and the filter screen plate 5 to be blocked will be shaken off to prevent the filter screen plate 4 and the filter screen plate 5 from being blocked and affecting the effect of separating impurities. The incoming raw materials are broken up by the auxiliary mechanism 18 to prevent large-volume lumps in the raw materials, and then the working pressure of the filter screen plate 4 and the filter screen plate 5 will be reduced. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
