Description

Technical Field

[0001] The utility model relates to the technical field of powder metallurgy, in particular to a powder segregation prevention discharge device. Background Art

[0002] Powder metallurgy is a process technology that produces metal powder or uses metal powder (or a mixture of metal powder and non-metal powder) as raw material, and then forms and sinters it to manufacture metal materials, composite materials and various types of products. After the powder is mixed by a horizontal mixer, it needs to be packaged in ton bags. During the processing, it is particularly important to ensure that the finished product does not produce segregation.

[0003] When an existing mixer is loading materials into a ton bag, in order to prevent powder segregation, the ton bag is usually placed on a lifting vehicle. As the loading progresses, the material level in the ton bag rises, and the lifting vehicle needs to be slowly lowered so that the powder in the ton bag and the mixer discharge port are always kept within a certain distance range, thereby achieving the effect of preventing segregation during loading.

[0004] However, when loading, a person is required to constantly observe the state of the bag and control the lifting of the lift truck at any time, which consumes manpower and cannot accurately grasp the lifting time. In addition, when the mixer is unloading, the powder in the ton bag always falls in one position, and the powder gradually accumulates to a state where the middle is high and the surroundings are low, which will affect the distance between the personnel observing the powder and the unloading port. The personnel need to constantly stir the bag to make it even, which is inconvenient to operate. After the ton bag is loaded, it needs to be moved to another place for weighing, which further reduces efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a powder anti-segregation discharging device with a higher degree of automation, which is convenient for personnel to operate, reduces personnel workload and improves bagging efficiency.

[0006] The utility model is realized through the following technical scheme: a powder anti-segregation discharge device, comprising a mixer and a lifting platform, wherein the lifting platform is located below a discharge port of the mixer, a ton bag is arranged on the lifting platform, the discharge port of the mixer is provided with a discharge pipe, a valve is installed on the discharge pipe, a material level sensor is arranged on the outer wall of the discharge pipe, and the material level sensor is electrically connected to a controller of the lifting platform.

[0007] The lifting platform of this solution is used to place ton bags. The mixer discharge port loads materials into the ton bags through the discharge pipe. The valve controls the discharge of the discharge pipe. During loading, the material level in the ton bag is sensed in real time by the material level sensor set on the discharge pipe, and the distance between the discharge pipe port and the powder is judged, so as to control the descent of the lifting platform to prevent powder segregation. The sensing is more accurate and the degree of automation is higher, which reduces the work of personnel and improves the bagging efficiency.

[0008] As an optimization, the discharge port of the feed pipe is provided with a rotary distributor. This optimization solution distributes the material evenly into the ton bag through the rotary distributor to avoid the accumulation of powder, further reduce the work of personnel, and improve the bagging efficiency.

[0009] As an optimization, an electronic scale is provided on the lifting platform. This optimization scheme uses an electronic scale to weigh the powder weight of the ton bag in real time, which is more convenient to use and further improves work efficiency.

[0010] As an optimization, the weight sensor of the electronic scale is electrically connected to the controller of the valve. In this optimization solution, when the weight of the powder material weighed by the electronic scale reaches a threshold, the valve is controlled to close and stop feeding, which is more automated and more convenient to use.

[0011] As an optimization, the valve is a star-shaped discharge valve. This optimization solution seals the discharge pipe through the star-shaped discharge valve to prevent air backflow and can discharge materials evenly.

[0012] The beneficial effects of the utility model are as follows: the lifting platform is used to place ton bags. When the mixer loads the ton bags through the feeding pipe, the material is evenly discharged through the star-shaped discharge valve, and the material is evenly distributed through the rotating distributor. During the distribution process, the material level in the ton bag is sensed in real time by the material level sensor, and the distance between the feeding pipe port and the powder is judged, so as to control the descent of the lifting platform to prevent the segregation of the powder. The sensing is more accurate, the work of personnel is reduced, and the bagging efficiency is improved. An electronic scale is installed on the lifting platform to weigh the ton bags in real time. When the set threshold is reached, the weight sensor of the electronic scale controls the star-shaped discharge valve to stop discharging, so as to realize automatic loading, reduce the work of personnel, and improve the bagging efficiency.

[0017] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0018] like Figure 1~2As shown, a powder anti-segregation discharge device includes a mixer 1 and a lifting platform 3, wherein the lifting platform 3 is located below the discharge port of the mixer 1, and a ton bag 5 is arranged on the lifting platform. In this embodiment, the lifting platform 3 adopts an electric lifting mechanism, and the lifting platform 3 and the mixer 1 are both existing conventional technologies.

[0019] An electronic scale 4 is provided on the top of the lifting platform 3. Specifically, the electronic scale 4 includes a placement plate 42 and weight sensors 41 fixed to the four corners of the bottom of the placement plate, one end of the weight sensor 41 is fixed to the placement plate 42, and the other end is fixed to the top plate of the lifting platform 3. The ton bag 5 is placed on the placement plate 42 of the electronic scale.

[0020] The mixer 1 is fixedly connected to a vertical feeding pipe 2, and the feeding pipe 2 is provided with a valve, and the valve in this embodiment is a star-shaped discharge valve 6, to achieve uniform feeding. The feeding pipe 2 is provided with a rotary distributor 8 at its outlet to achieve uniform feeding.

[0021] The weight sensor 41 of the electronic scale 4 in this embodiment is electrically connected to the valve controller. Specifically, the weight sensor 41 is electrically connected to the start-stop controller of the star-shaped discharge valve 6. Before use, the threshold of the weight sensor 41 is set according to the weight of the ton bag 5 when it is full. When the weight of the powder reaches the threshold, the weight sensor 41 sends a signal to the start-stop controller of the star-shaped discharge valve 6, and the star-shaped discharge valve 6 stops discharging.

[0022] A material level sensor 7 is provided on the outer wall of the feeding pipe 2, and the material level sensor 7 is electrically connected to the controller of the lifting platform 3. Specifically, the material level sensor 7 is an infrared distance sensor, and the material level sensor 7 is arranged at the lower end of the outer wall of the feeding pipe 2 to measure the distance from the lower end of the feeding pipe to the powder in the ton bag in real time. The material level sensor 7 is electrically connected to the lifting controller of the lifting platform 3, and the lifting and lowering of the lifting platform 3 is adjusted in real time according to the measured spacing to prevent powder segregation.

[0023] Working principle: The ton bag 5 is placed on the placement plate 42 of the electronic scale 4. The lifting platform 3 rises to allow the discharge pipe 2 to extend into the ton bag 5 to discharge the material. The star-shaped discharge valve 6 is started to discharge the material evenly, and the powder is evenly distributed in the ton bag through the rotating distributor 8. The distance to the powder is detected by the material level sensor 7. When the distance is less than the set value, the material level sensor 7 feeds back a signal to the lifting controller to control the lifting platform 3 to descend to prevent the segregation of the powder. The weight of the powder in the ton bag is monitored in real time by the weight sensor 41 of the electronic scale 4. When the weight reaches the set value, the weight sensor 41 feeds back a signal to the start-stop controller of the star-shaped discharge valve 6 to stop discharging the material, and the personnel remove the ton bag and pack it to complete the bagging.
