Description

Technical Field

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

[0002] Powder silo is a device used to store and transport various powdered materials. Powder silo is widely used in chemical, energy, metallurgy, packaging, food and pharmaceutical industries. It is used for unloading, storage, dust removal, metering, feeding and other links in the production process of solid granular materials, flaky materials, powders and powder-particle mixtures.

[0003] When the material in the powder silo is discharged from its bottom outlet, the outlet is often blocked. In the prior art, the outlet is generally vibrated to avoid blockage. However, due to the large volume of the powder silo, the material at the bottom port is subjected to a large accumulation pressure. The measure of using vibration to avoid blockage of the outlet cannot achieve a good unblocking effect in actual application. For this reason, we propose a discharge device for the powder silo to solve the problem that the outlet of the powder silo is easily blocked. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art and proposes a discharge device for a powder bin.

[0008] Preferably, a feeding pipe is connected to the upper end of the powder bin.

[0009] Preferably, a support column is provided at the bottom of the powder silo, and three support columns are evenly distributed along the bottom of the powder silo.

[0010] By adopting the above technical solution, the support column provides support for the entire powder silo main structure.

[0011] Preferably, the discharge port is a cylindrical outlet and a solenoid valve is installed on the discharge port.

[0012] Preferably, the bracket is a circular frame structure, a clamping strip is provided on the inner side of the bracket, a clamping groove is provided on the side of the sliding plate seat, and the clamping strip is slidably connected to the clamping groove.

[0013] By adopting the above technical solution, the sliding connection between the snap-in strip and the snap-in groove limits the front-to-back deviation of the sliding plate seat inside the bracket, so that the sliding plate seat can only slide in the vertical direction along the snap-in strip, providing a stable guiding effect for the skateboard seat.

[0014] Preferably, a support rod is fixedly connected between the fixed disc and the sliding plate seat, and a brace rod is arranged at the bottom of the support rod.

[0015] Preferably, an oblique section is provided on the upper side of the support rod.

[0016] Preferably, a top cap is fixedly mounted on the upper side of the fixed disc, the upper end of the rotating shaft rotates through the top cap, and the top cap is a conical structure.

[0017] By adopting the above technical solution and setting the inclined section on the support rod, when the material in the powder bin falls to the upper end of the support rod, due to the setting of the inclined section, the material will not accumulate on the upper end of the support rod, and will fall into the corresponding receiving container under the guidance of the inclined section on the upper end of the support rod. The conical structure design of the top cap is similar to the inclined section design, which also prevents the material from accumulating on the top cap.

[0018] Preferably, the upper and lower ends of the lateral support rods are fixedly connected to connecting rods, and the connecting rods are fixedly mounted on the side walls of the rotating shaft.

[0020] By adopting the above technical solution, when the spiral blade rotates inside the discharge port, when the roller arranged on the side of the spiral blade contacts the inner wall of the discharge port, rotational contact occurs between the roller and the inner wall of the discharge port, thereby preventing the spiral blade from scratching the inner wall of the discharge port.

[0021] Compared with the related art, the discharge device of the powder bin proposed by the utility model has the following beneficial effects:

[0022] In the utility model, the discharge device of the powder bin is provided with a discharge mechanism. When the outlet of the powder bin is blocked, the first motor in the discharge mechanism is used to drive the threaded rod to rotate. Under the drive of the threaded rod, the sliding plate seat is raised, and then the fixed disc on the side of the sliding plate seat is driven to rise, so that the rotating shaft on the fixed disc and the spiral piece on the rotating shaft are inserted into the discharge port, and then the second motor is started to rotate. Under the rotation of the second motor, its output end drives the rotating shaft and the spiral piece on the rotating shaft to rotate inside the discharge port, and under the rotation of the spiral piece, the powder bin outlet is discharged. The material in the material port is conveyed downward, providing active conveying power, thereby preventing the material in the discharge port from being blocked. In addition, a roller is rotatably arranged on the outside of the spiral blade. When the spiral blade rotates, the roller on the outside of the spiral blade is driven to rotate and contact with the inner wall of the discharge port, preventing the spiral blade from scratching the inner wall of the discharge port, thereby improving practicality. At the same time, the entire discharge mechanism adopts a design that is separated from the main body of the powder silo, so that the discharge mechanism can be used as a temporary tool to deal with blockages, and it does not affect the working performance of the main body of the powder silo when it is working.

[0030] In this embodiment, the discharging mechanism 7 includes a bracket 71, a first motor 73 is fixedly installed on the upper end of the bracket 71, a sliding plate seat 72 is slidably installed on the inner side of the bracket 71, a threaded rod 74 is fixedly connected to the output end of the first motor 73, the threaded rod 74 is rotatably installed on the inner side of the bracket 71 and the threaded rod 74 is screwed through the sliding plate seat 72, a fixed disk 78 is arranged on the side of the sliding plate seat 72, a second motor 79 is installed at the bottom of the fixed disk 78, a rotating shaft 711 is fixedly installed on the output end of the second motor 79, the rotating shaft 711 rotates through the upper side of the fixed disk 78 and a spiral sheet 712 is fixedly installed on the rotating shaft 711, a lateral support rod 713 is installed on the outer side of the rotating shaft 711, a roller 714 is rotatably sleeved on the lateral support rod 713, the upper and lower ends of the lateral support rod 713 are fixedly connected to connecting rods, and the connecting rods are fixedly installed on the side walls of the rotating shaft 711.

[0031] Through the above structure, starting the first motor 73 can drive the threaded rod 74 to rotate. When the threaded rod 74 rotates, it drives the sliding plate seat 72 to slide up and down along the inner side of the bracket 71. The first motor 73 can drive the rotating shaft 711 set on the side of the sliding plate seat 72 and the spiral piece 712 thereon to extend into the inner side of the discharge port 4. Subsequently, starting the second motor 79 can drive the spiral piece 712 to rotate, thereby transporting the material in the discharge port 4 to prevent the material in the discharge port 4 from being blocked.

[0032] In this embodiment, the bracket 71 is a circular frame structure, a clamping strip is provided inside the bracket 71, a clamping groove is provided on the side of the sliding plate seat 72, and the clamping strip is slidably connected to the clamping groove.

[0033] Through the above structure, the sliding connection between the snap-in strip and the snap-in groove limits the displacement of the sliding plate seat 72 in the front-to-back direction inside the bracket 71, so that the sliding plate seat 72 can only slide in the vertical direction along the snap-in strip, thereby making the sliding plate seat 72 more stable when sliding up and down under the drive of the threaded rod 74.

[0034] In this embodiment, a support rod 75 is fixedly connected between the fixed disc 78 and the sliding plate seat 72 , a support rod 76 is provided at the bottom of the support rod 75 , and an oblique section 77 is provided on the upper side of the support rod 75 .

[0038] In this embodiment, the roller 714 is made of elastic rubber, and the roller 714 is in rotational contact with the spiral sheet 712 .

[0039] With the above structure, when the spiral blade 712 rotates on the inner side of the discharge port 4, since the roller 714 is arranged on the outer side of the spiral blade 712, when it contacts the inner wall of the discharge port 4, the roller 714 first rotates and contacts the inner wall of the discharge port 4, thereby preventing the spiral blade 712 from scratching the inner wall of the discharge port 4.

[0040] In the present invention, when in use, when the discharge port 4 at the bottom of the powder bin 1 is blocked, the first motor 73 in the discharge mechanism 7 is started to rotate, and the first motor 73 drives the threaded rod 74 to rotate, and the sliding plate seat 72 is driven by the threaded rod 74 to rise, thereby driving the fixed disc 78 on the side of the sliding plate seat 72 to rise, so that the rotating shaft 711 on the fixed disc 78 and the spiral piece 712 outside the rotating shaft 711 are inserted into the feed port 4, and then the second motor 79 is started to rotate. Under the rotation of the second motor 79, its output end drives The rotating shaft 711 and the spiral blade 712 on the rotating shaft 711 rotate on the inner side of the discharge port 4. The rotation of the spiral blade 712 conveys the material in the discharge port 4 downward, providing active conveying power, thereby preventing the material in the discharge port 4 from being blocked. Since the roller 714 is rotatably arranged on the outer side of the spiral blade 712, when the spiral blade 712 rotates, the roller 714 on the outer side of the spiral blade 712 is driven to rotate and contact with the inner wall of the discharge port 4, thereby preventing the spiral blade from scratching the inner wall of the discharge port 4, thereby improving practicality.
