[0002] Asphalt mixing plants, or asphalt mixture mixing equipment, are essential core equipment in asphalt pavement construction. To produce precisely proportioned asphalt mixtures, asphalt mixing plants place extremely high demands on metering accuracy. To ensure the accuracy of the weighing scales, flexible joint seals are required at the inlet and outlet of the weighing hopper. Furthermore, to compensate for manufacturing errors, flexible joint seals are often used at component joints. The production process of asphalt mixing plants generates significant amounts of dust, and since the building interior maintains a constant negative pressure environment, the flexible joint seals must be dust-proof and prevent loosening due to the negative pressure.

[0003] The current soft connection sealing structure of asphalt mixing plant buildings mainly adopts the form of silicone rubber sealing cloth and rubber sealing strips. The silicone rubber sealing cloth is not airtight and will bulge outward under the negative pressure environment of the building. The rubber sealing strips will not be stuck and will become loose under repeated stress. Once the soft connection is detached, a large amount of dust will be emitted outward, affecting the product image. Summary of the Invention

[0004] In view of the problems existing in the above-mentioned prior art, the utility model provides a soft connection sealing structure for an asphalt mixing station, which has a simple structure, can meet the requirements of no loosening and no dust emission, and improve the overall image of the product.

[0007] A plurality of fixing clips are installed at the connection between the sealing cloth and the first component and the sealing cloth and the second component, and fixing bolts are installed on the fixing clips for fastening the upper side of the sealing cloth to the first component and the lower side of the sealing cloth to the second component;

[0008] The fixed clamping plate is located on one side of the fixing clamp close to the fixing bolt, and the fixing bolt passes through the side wall of the fixing clamp to squeeze the fixed clamping plate and compress the sealing cloth.

[0009] In some embodiments, the sealing cloth is made of composite aramid material.

[0010] In some embodiments, a plurality of straight pressure plates are further included, wherein the straight pressure plates are installed on a side of the fixing clamp away from the fixing bolts.

[0011] In some embodiments, arc-shaped pressing plates are installed at the connecting corners of the sealing cloth and the first component and the second component, and the arc-shaped pressing plates are pressed by fixing clamps.

[0012] In some embodiments, the straight pressing plate and the curved pressing plate have the same thickness.

[0013] In some embodiments, the fixing clip is an integrally formed U-shaped clip.

[0014] In some embodiments, a threaded hole is formed on one side wall of the fixing clamp, and the fixing bolt is threadedly connected to the threaded hole.

[0015] In some embodiments, the length of the fixing clamp pressure plate is the same as the length of the fixing clamp.

[0016] In some embodiments, the first component is a hot aggregate storage system, and the second component is an aggregate weighing hopper.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0027] like Figure 1-Figure 4 As shown, a soft connection sealing structure for an asphalt mixing plant includes a sealing cloth 1, a fixing clamp 4 and a fixing clamp pressure plate 6;

[0028] The sealing cloth 1 is formed into a ring shape, the upper circumference of the ring-shaped sealing cloth 1 wraps around the bottom plate of the first component, and the lower circumference wraps around the top plate of the second component. The sealing cloth 1 is used to softly connect the first component and the second component;

[0029] A plurality of fixing clips 4 are installed at the connection between the sealing cloth 1 and the first component, and the sealing cloth 1 and the second component. Fixing bolts 5 are installed on the fixing clips 4. The fixing clips 4 cooperate with the fixing bolts 5 to fasten the upper side of the sealing cloth 1 to the first component and the lower side of the sealing cloth 1 to the second component.

[0030] The fixed clamping plate 6 is located on one side of the fixing clamp 4 close to the fixing bolt 5. The fixing bolt 5 passes through the side wall of the fixing clamp 4 to squeeze the fixed clamping plate 6 and press the sealing cloth 1. The fixed clamping plate 6 can prevent the fixing bolt 5 from directly contacting the sealing cloth 1 and causing damage.

[0031] In some embodiments, the sealing cloth 1 is made of composite aramid material, which is breathable, dust-proof, water-repellent and oil-proof. The use of composite aramid sealing cloth 1 reduces the impact of the negative pressure of the asphalt mixing plant building on the sealing cloth 1.

[0032] In some embodiments, as Figure 1 、 Figure 2 As shown, it also includes a plurality of straight pressing plates 2 for improving the pressing effect on the sealing cloth 1. The straight pressing plates 2 are arranged at a certain interval. The straight pressing plates 2 are installed in the fixing clamp 4 on the side away from the fixing bolt 5. The fixing bolt 5 and the fixing clamp pressure plate 6 are squeezed to press the straight pressing plates 2 on the other side of the sealing cloth 1 (away from the fixing bolt 5). Figure 4 The straight pressing plate 2 can be designed to have different lengths according to actual needs.

[0033] In some embodiments, as Figure 1 、 Figure 2 As shown, arc-shaped pressing plates 3 are installed at the connecting corners of the sealing cloth 1 and the first and second components. The arc-shaped pressing plates 3 press the sealing cloth 1 through the fixing clamps 4. The arc-shaped pressing plates 3 can avoid blind corners where ash leaks.

[0034] In some embodiments, as Figure 1 、 Figure 2 As shown, the straight pressing plate 2 and the arc pressing plate 3 have the same thickness and are easy to process. The straight pressing plate 2 and the arc pressing plate 3 are pressed tightly on the same side of the sealing cloth 1, thereby improving the sealing performance of the soft connection between the first component and the second component.

[0035] In some embodiments, as Figure 1 、 Figure 2 As shown, the fixing clip 4 is an integrally formed U-shaped clip with strong rigidity. By being used in conjunction with the fixing bolt 5, the sealing cloth 1 can be firmly fixed at the connection between the two components to achieve a soft connection.

[0036] In some embodiments, a threaded hole is opened on one side wall of the fixing clamp 4, and the fixing bolt 5 is threadedly connected to the threaded hole. By tightening the fixing bolt 5, the fixing clamp pressure plate 6 can be controlled to cooperate with the straight pressure plate 2 and the arc pressure plate 3 to press the sealing cloth 1 in the fixing clamp 4, which makes the operation more convenient and labor-saving.

[0037] In some embodiments, the length of the fixing clamping plate 6 is the same as that of the fixing clamp 4 , which facilitates processing and prevents the fixing bolt 5 from directly contacting the sealing cloth 1 and causing damage to the sealing cloth 1 .

[0038] In some embodiments, as Figure 3 、 Figure 4 As shown, the first component and the second component may be any two connected components in the asphalt mixing plant, for example, the first component may be the hot aggregate storage system 7 and the second component may be the aggregate weighing hopper 8.

[0039] Take the connection between the hot aggregate storage system 7 and the aggregate weighing hopper 8 as an example:

[0040] like Figure 3 、 Figure 4 As shown, a sealing cloth made of composite aramid material is formed into a ring shape around the connection between the hot aggregate storage system 7 and the aggregate weighing hopper 8, and the upper side of the sealing cloth 1 is wrapped around the circumference of the lower connecting plate of the hot aggregate storage system 7, and then installed at the connection between the sealing cloth 1 and the hot aggregate storage system 7 through multiple fixing clips 4, and a fixing clamp pressure plate 6, a straight pressure plate 2 and an arc pressure plate 3 are placed in the fixing clamp 4 respectively, wherein the arc pressure plate 3 is arranged at the corner, and then tightened on the fixing clamp 4 through the fixing bolts 5 on the upper side of the fixing clamp 4, and the fixing clamp pressure plate 6 is squeezed by the fixing bolts 5, and at the same time, the straight pressure plate 2 and the arc pressure plate 3 press the sealing cloth 1 until the upper side of the sealing cloth 1 is connected and fastened to the hot aggregate storage system 7;

[0041] Continue to wrap the lower side of the sealing cloth 1 around the upper connecting plate of the aggregate weighing bucket 8, and then install it at the connection between the sealing cloth 1 and the aggregate weighing bucket 8 through multiple fixing clips 4, and place the fixing clamp pressure plate 6, straight pressure plate 2 and arc pressure plate 3 in the fixing clamp 4 respectively. The arc pressure plate 3 is also arranged at the corner, and then tighten it on the fixing clamp 4 through the fixing bolts 5 under the fixing clamp 4, squeeze the fixing clamp pressure plate 6 through the fixing bolts 5, and at the same time make the straight pressure plate 2 and the arc pressure plate 3 press the sealing cloth 1 until the lower side of the sealing cloth 1 is connected and fastened to the aggregate weighing bucket 8.

[0042] The utility model discloses a soft connection sealing structure for an asphalt mixing station, which uses a sealing cloth to perform soft connection of stairs, thereby solving the problem of dust leakage caused by loosening of the soft connection and improving the product image.

[0043] Furthermore, those skilled in the art will appreciate that, although some embodiments described herein include certain features included in other embodiments but not other features, combinations of features from different embodiments are also intended to fall within the scope of protection of the present invention and form different embodiments. For example, in the above embodiments, those skilled in the art will be able to use them in combination based on the known technical solutions and the technical problems to be solved by this application.
