Description

Technical Field

[0001] This utility model belongs to the technical field of mixing equipment components, and in particular relates to a vibration device for mixing equipment. Background Technology

[0002] like Figure 4 As shown, this is a vibration device for mixing equipment in the prior art. For example, the corresponding structure of the vibration device is disclosed in the utility model patent with publication number CN215877497U.

[0003] In actual use, the aforementioned vibration device suffers from several drawbacks. The sealing component 3 is installed by bolting through the sealing ring, which compromises its performance. Furthermore, since the top of the surrounding mixing pipe 6 passes through the mixing chamber 5 before connecting to the vibration component 4, a certain distance must be maintained between the point where the surrounding mixing pipe 6 passes through the mixing chamber 5 and the mixing chamber 5 to avoid affecting its vibration. Figure 4 The gap indicated at point A means that during use, dust dispersed from the mixing chamber 5 due to the vibration of the surrounding mixing pipes 6 will inevitably drift into the sealing support 2 in large quantities through the gap. Consequently, during long-term operation, the dust drifting into the sealing support 2 will accelerate the wear of the sealing component 3, affecting the sealing performance and ultimately impacting the service life of the sealing component 3. Therefore, there are still shortcomings and deficiencies in the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide a vibration device for mixing equipment to solve the problems mentioned in the background art.

[0005] The technical solution adopted by this utility model to solve the above problems is as follows: A vibration device for a blending equipment includes a blending chamber and surrounding blending pipes. Vertically distributed sealing supports are installed on the top of the blending chamber. Vibration components are installed on the top of the surrounding blending pipes after they slide through the blending chamber and the sealing supports. A spring is installed between the vibration components and the sealing supports and is sleeved on the sealing supports. The sealing supports are tubular structures with open ends. A sealing component sleeved on the surrounding blending pipes is installed inside the top of the sealing supports. The bottom of the sealing supports extends into the blending chamber, and a restraining bag that can prevent powder leakage is fitted between the bottom of the sealing supports and the surrounding blending pipes.

[0006] Furthermore, both ends of the restraint bag are detachably fitted onto the sealing support and the surrounding mixing tube via fastening strap assemblies.

[0007] Furthermore, an annular groove is provided on the outer wall of the sealing support, and the fastening band assembly installed on the sealing support is positioned opposite to the annular groove.

[0008] Furthermore, a first annular disc is coaxially mounted on the bottom of the sealing support and sleeved on the surrounding mixing pipes. Several elastic support plates capable of supporting and stretching the restraining bag are mounted on the bottom surface of the first annular disc.

[0009] Furthermore, the sealing assembly includes a second annular disc installed inside the sealing support and fitted onto the surrounding mixing tubes. The second annular disc is equipped with a plurality of sealing rings that are sequentially fitted onto the surrounding mixing tubes from top to bottom and are adapted to the outer diameter of the surrounding mixing tubes. A sealing cap fitted onto the surrounding mixing tubes is coaxially installed at the top of the sealing support.

[0010] Furthermore, a flange is coaxially fitted on the top of the sealing support, the edge of the sealing gland is located outside the sealing support, and the flange and the sealing gland are connected by a number of vertically distributed first bolt pairs that are equidistantly distributed along the circumference of the flange.

[0011] Furthermore, an annular gasket is installed between the flange and the sealing gland.

[0012] Furthermore, the sealing support is fitted with a spring support installed on the top of the mixing chamber, and a cover plate is coaxially installed on the top of the surrounding mixing pipes.

[0016] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0017] like Figures 1 to 3 As shown, this utility model provides a vibration device for a blending equipment, including a blending chamber 5 and surrounding blending pipes 6. A vertically distributed sealing support 2 is installed on the top of the blending chamber 5. A vibration component 4 is installed on the top of the surrounding blending pipes 6 after sliding through the blending chamber 5 and the sealing support 2. A spring 7 is installed between the vibration component 4 and the sealing support 2 and sleeved on the sealing support 2. The sealing support 2 is a tubular structure with open ends. A sealing component 3 is installed inside the top of the sealing support 2 and sleeved on the surrounding blending pipes 6. Specifically, the sealing support 2, sealing component 3, vibration component 4, spring 7, blending chamber 5 and surrounding blending pipes 6 are all prior art.

[0018] Based on this, the bottom of the sealing support 2 extends into the mixing chamber 5. Specifically, the sealing support 2 is welded to the mixing chamber 5 at the point where it penetrates the mixing chamber 5. A restraining bag 1 is fitted between the bottom of the sealing support 2 and the outer wall of the surrounding mixing pipe 6 to prevent powder leakage. The restraining bag 1 can be set as a dust filter bag. Specifically, during use, the restraining bag 1 can act as an isolation and protection against diffused dust leakage into the sealing support 2, and the vibration of the surrounding mixing pipe 6 will not be transmitted to the sealing support 2 through the restraining bag 1. This can effectively prevent a large amount of dust from entering the sealing support 2, thereby reducing the impact of dust on the sealing performance of the sealing component 3 in the sealing support 2 during long-term operation and improving the service life of the sealing component 3.

[0019] Furthermore, such as Figure 1 and Figure 3 As shown, the two ends of the restraint bag 1 are detachably fitted onto the sealing support 2 and the surrounding mixing tube 6 via fastening strap assemblies 8. Specifically, the fastening strap assembly 8 can be set as a metal clamp strap, elastic band, or fastening strap with Velcro at both ends, which facilitates the assembly and disassembly of the restraint bag 1.

[0020] Furthermore, an annular groove is provided on the outer wall of the sealing support 2, and the fastening strap assembly 8 installed on the sealing support 2 is positioned opposite to the annular groove. In this way, during use, the fastening strap assembly 8 can clamp the bag body of the restraining bag 1 into the annular groove to ensure the firmness of the restraining bag 1 on the sealing support 2.

[0021] Furthermore, such as Figure 1 and Figure 3 As shown, a first annular disk 21 is coaxially installed at the bottom of the sealing support 2 and sleeved on the surrounding mixing pipes 6. Several elastic support plates 9 are installed on the bottom surface of the first annular disk 21, which can expand the binding bag 1. The support plates 9 can be made of polyurethane. Specifically, each support plate 9 is vertically arranged, and several support plates 9 are equidistantly distributed along the circumference of the first annular disk 21. The outer surface of each support plate 9 is also set as an inclined surface, which can fully expand the binding bag 1 to form a conical structure with a wide top and narrow bottom, so as to ensure that the binding bag 1 has sufficient isolation and protection area. Secondly, under the elastic action of the support plate 9, when the dispersed dust breaks through the binding bag 1 due to vibration and impact, the support plate 9 can play a buffering role. Moreover, multiple support plates 9 can also isolate the vibration of the surrounding mixing pipes 6, so as to improve the stability of the device and reduce maintenance requirements.

[0022] The specific configuration of sealing component 3 is as follows: Figure 1 and Figure 2 As shown, the sealing assembly 3 includes a second annular disk 31 installed inside the sealing support 2 and fitted onto the surrounding mixing pipes 6. Several sealing rings 32, each matching the outer diameter of the surrounding mixing pipes 6, are installed on the second annular disk 31, sequentially fitted from top to bottom onto the surrounding mixing pipes 6. A sealing cap 33, fitted onto the surrounding mixing pipes 6, is coaxially installed at the top of the sealing support 2. Specifically, the sealing cap 33 cooperates with the second annular disk 31 to press the sealing rings 32 into the sealing support 2. The number of sealing rings 32 can be set to three, and the three sealing rings 32 can be arranged from bottom to top as follows: Figure 2 The flat ring silicone seal and two ball ring rubber seals are shown. In use, by stacking multiple layers of seals 32 made of different materials, the sealing performance of the sealing component 3 can be improved to prevent dust from seeping out and to provide a buffer threshold for the spring 7.

[0023] Furthermore, such as Figure 1 and Figure 2As shown, a flange 34 is coaxially fitted onto the top outer side of the sealing support 2. The edge of the sealing gland 33 is located outside the sealing support 2. The flange 34 and the sealing gland 33 are connected by several vertically distributed first bolt connection pairs 35 equidistantly distributed along the circumference of the flange 34. The first bolt connection pairs 35 are existing technology and include a first connecting bolt, a first nut, and a first gasket. Specifically, by connecting the sealing gland 33 and the flange 34 using the first bolt connection pairs 35 on the outside of the sealing support 2, the first bolt connection pairs 35 can prevent them from penetrating and damaging the sealing ring 32, thus ensuring the original performance of the sealing ring 32 and further improving the service life of the sealing assembly 3. In addition, as Figure 1 and Figure 2 As shown, an annular gasket 36 is installed between the flange 34 and the sealing gland 33.

[0024] The specific settings for vibration component 4 are as follows: Figures 1 to 3 As shown, the sealing support 2 is fitted with a spring support 10 fixedly installed on the top of the mixing chamber 5. The top of the mixing pipes 6 around the perimeter is coaxially mounted with a cover plate 61. The vibration assembly 4 includes a vibration bracket 41. The vibration bracket 41 and the cover plate 61 are connected by a second bolt connection pair 42. The second bolt connection pair 42 is existing technology and includes a second connecting bolt, a second nut and a second washer. A vibrator 43 is installed on the vibration bracket 41. The two ends of the spring 7 abut against the vibration bracket 41 and the spring support 10 respectively. Specifically, the arrangement of the vibration assembly 4 is the same as that of the existing technology.
