Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of powder conveying equipment, specifically to a conical stirring anti-bridging device. Background Technology
[0002] In powder conveying systems of industries such as plastics, rubber, food, pharmaceuticals, and daily chemicals, bridging can easily occur in the silo due to friction between powder particles or between powder and silo, as well as factors such as air temperature and humidity. This affects the continuity of silo unloading, and in severe cases, can lead to unloading difficulties or even interruptions. Bridging is sometimes also referred to as arching, bridging, or silo bridging. Therefore, those skilled in the art have provided a conical stirring anti-bridging device to solve the problems mentioned in the background art. Summary of the Invention
[0003] The purpose of this invention is to provide a conical stirring anti-bridging device to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: it includes a silo bottom plate, a geared motor, an output shaft, a support sleeve, a skeleton sealing ring, a conical activator, a flange, stirring blades, and a discharge port; the geared motor is installed at the bottom of the silo bottom plate, a hole is opened in the center of the silo bottom plate, a support sleeve is fixed in the hole, a skeleton sealing ring is installed between the support sleeve and the silo bottom plate, the output shaft of the geared motor passes through the support sleeve and is rotatably connected to the support sleeve through a bearing, a flange is fixed on the output shaft, a conical activator is fixed on the flange, several stirring blades are fixed on the outer periphery of the flange, and several discharge ports are provided on the silo bottom plate.
[0005] Furthermore, the bottom plate of the hopper is circular in shape.
[0006] Furthermore, the number of stirring blades is 2 to 3.
[0007] Furthermore, the number of discharge ports is 1 to 4.
[0008] The beneficial effects of this utility model after adopting the above structure are as follows: The conical stirring anti-bridging device of this utility model, with the conical shape of the conical activator combined with the stirring rotation of the paddle, can effectively prevent material bridging and has a very good arch-breaking effect, making the material conveying of automated conveying equipment such as pneumatic conveying or screw conveying smoother.

[0012] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0013] See as Figure 1 As shown, this specific embodiment adopts the following technical solution: It includes a silo bottom plate 1, a reduction motor 2, an output shaft 3, a support sleeve 4, a skeleton sealing ring 5, a conical activator 6, a flange 7, stirring blades 8, and a discharge port 9; the reduction motor 2 is installed at the bottom of the silo bottom plate 1, a hole is opened in the center of the silo bottom plate 1, a support sleeve 4 is fixed in the hole, a skeleton sealing ring 5 is installed between the support sleeve 4 and the silo bottom plate 1, the output shaft 3 of the silo bottom plate 1 and the reduction motor 2 pass through the support sleeve 4, and are rotatably connected to the support sleeve 4 through a bearing, the skeleton sealing ring 5 prevents dust and impurities from entering the bearing, a flange 7 is fixed on the output shaft 3, a conical activator 6 is fixed on the flange 7, and two stirring blades 8 are fixed on the outer periphery of the flange 7.
[0014] The working principle of this utility model is as follows: The deceleration motor 2 drives the conical activator 6 and the stirring blade 8 on the flange 7 to rotate simultaneously. The rotation of the stirring blade 8 stirs the material at the bottom of the silo towards the discharge port 9. At the same time, due to the conical shape of the conical activator 6, which has a guiding effect, and because it is a powder material, the rotation of the conical activator 6 can guide the upper material towards the discharge port 9 to accelerate the discharge speed, break the arch, and effectively prevent the material from bridging in the silo. The bottom plate 1 of the silo is circular so that multiple discharge ports 9 can be set on the bottom plate 1. The four discharge ports 9 can achieve the purpose of feeding material from one point to four points, improving practicality and reducing equipment investment costs.
[0015] The entire device is made of 304 stainless steel and the outer surface is polished, making it smooth, clean, and free from contamination of raw materials. The whole device is compact and aesthetically pleasing.
[0016] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
