Description

Technical Field

[0001] The utility model relates to the field of conveying, and particularly relates to a decompression cone. Background Art

[0002] In the production of photovoltaic glass alkali, silica sand is an important raw material and also the raw material with the largest consumption. In daily production, silica sand is stored in a silica sand bin by means of belt and bucket elevator transportation. Since the impact force on the bin body is relatively large when the silica sand enters the bin, an umbrella-shaped decompression cone is often used to buffer and decompress the silica sand about to enter the bin and reduce the impact of the silica sand on the bin body. However, when some silica sand in the bin is agglomerated or formed into lumps due to the fluctuation of moisture content, the accumulation of some raw materials together will cause slow feeding at the decompression cone, and may also cause the problem that the materials at the decompression cone cannot be normally fed due to the adhesion of the agglomerated and formed materials to the bin wall. This not only brings great inconvenience to users, but also affects normal production operations. Summary of the Utility Model

[0026] Refer to Figure 1, A decompression cone, comprising: a frustum 100, a diversion structure 500 and a shock absorption structure 600. The side of the frustum 100 is provided with an inclined surface; the diversion structure 500 is arranged on the inclined surface, and the diversion structure 500 forms multiple convex or concave parts at the inclined surface. The diversion structure 500 is used to guide the raw material to move from one end of the frustum 100 to the other end; the shock absorption structure 600 is arranged on the frustum 100, and the shock absorption structure 600 is used to reduce the impact force when the raw material contacts the frustum 100. When the raw material is poured into the bin, it will first contact the frustum 100 and move on the inclined surface of the frustum 100. During this process, the diversion structure 500 will divert the raw material. Since the diversion structure 500 forms multiple convex or concave parts at the inclined surface, when the raw material moves, it will be dispersed and fall respectively between two adjacent convex parts, or fall respectively into different concave parts. Thus, the effect of directly and effectively dispersing the material can be achieved, and further, problems such as caking or agglomeration of the raw material can be effectively alleviated or avoided. The shock absorption structure 600 can effectively reduce the impact force between the raw material and the frustum 100, thereby effectively protecting the frustum 100 and avoiding the problem of excessive loss of the decompression cone due to the impact of the raw material, and further effectively improving the service life of the decompression cone.

[0027] In some embodiments, referring to Figure 2 , the diversion structure 500 includes a plurality of through holes 150 opened in the frustum 100, and one end of the through hole 150 communicates with the inclined surface. When the raw material is poured onto the frustum 100, it will flow on the inclined surface. During this process, the raw material will be dispersed and fall into different through holes 150. Since the radial dimension of the through hole 150 is limited, the volume of the agglomerates formed by the raw material entering the through hole 150 can be effectively reduced, and further, it can be smoothly ensured that the falling raw material will not have serious problems such as caking or agglomeration, and further, the raw material can be smoothly transported and used subsequently.

[0028] It can be expected that the diversion structure 500 can also be composed of other components, such as grooves or ribs opened on the inclined surface, so as to limit the maximum size of the raw material through the gaps between two adjacent grooves or ribs.

[0029] In some embodiments, referring to Figure 2 , each of the through holes 150 is evenly distributed around the frustum 100. The circumferential distribution of each of the through holes 150 enables the raw material to obtain the diversion effect of the through holes 150 when poured onto each position of the frustum 100, so as to ensure that the raw material can be dispersed under the action of the through holes 150 and avoid the problems of agglomeration and caking of the raw material.

[0030] Specifically, the frustum 100 has a plurality of inclined surfaces, and the number of through holes 150 distributed on each inclined surface is the same.

[0031] In some embodiments, referring to Figure 1 , the frustum 100 is a multi-pyramid, and there are multiple inclined surfaces distributed around the frustum 100; through holes 150 are provided on each inclined surface. The multi-pyramid guides the raw material through flat inclined surfaces, so that the force exerted by the inclined surface on the raw material when it slides can approach the same direction, and then the sliding movement of the raw material can be carried out more stably, so that the raw material can fall into each through hole 150 and be dispersed from each other.

[0032] Specifically, the frustum 100 is a hexagonal pyramid. Of course, the shape of the frustum 100 is not fixed. For example, the frustum 100 can be a conical frustum. The specific implementation manner is not unique, but can be adjusted according to the actual situation and is not limited here.

[0033] In some embodiments, referring to Figure 2 , at least part of the shock-absorbing structure 600 is located inside the frustum 100, and the through hole 150 penetrates the shock-absorbing structure 600. When the raw material is poured into the frustum 100, it will impact the frustum 100. At this time, since part of the shock-absorbing structure 600 is located inside the frustum 100, the shock-absorbing structure 600 can slow down the impact on the surface of the frustum 100 from the inside of the frustum 100, and thus effectively reduce the loss of the frustum 100 caused by the impact.

[0034] Specifically, the shock-absorbing structure 600 is divided into two parts. One part is located at the end of the frustum 100 and is used to directly contact the raw material, and the other part is located inside the frustum 100 and is used to reduce the impact force received by the frustum 100.

[0035] In some embodiments, referring to Figure 2 , the shock-absorbing structure 600 includes a shock-absorbing plate 300 provided at the top end of the frustum 100. The shock-absorbing plate 300 is used to contact the raw material and reduce the impact force of the raw material on the frustum 100. Before the raw material is poured from above the frustum 100 to the frustum 100, the shock-absorbing plate 300 will first bear the impact of the raw material, and then the raw material will slide from the shock-absorbing plate 300 to the frustum 100. Thus, the direct contact and impact during the pouring of the raw material are borne by the shock-absorbing plate 300, so that the impact force received by the frustum 100 and the corresponding loss problem can be effectively reduced.

[0036] In some embodiments, referring to Figure 3, a shock-absorbing spring 650 is provided inside the shock-absorbing plate 300. The shock-absorbing spring 650 is located at the end of the frustum 100 and is used to provide an elastic force between the shock-absorbing plate 300 and / or the frustum 100. When the shock-absorbing plate 300 is subjected to the impact force of the raw material on it, the impact force of the raw material on it will be transmitted to the shock-absorbing spring 650, and the shock-absorbing spring 650 will be in a tension or compression state. At this time, the shock-absorbing spring 650 will exert a reverse elastic force on the shock-absorbing plate 300 under the action of its own elasticity, and the elastic force and the impact force of the raw material will cancel each other out, so as to successfully achieve the effect of alleviating the impact force and facilitate the protection of the frustum 100.

[0037] It can be expected that the shock-absorbing plate 300 can be directly provided at the top of the frustum 100, or can be provided inside the frustum 100 as a sandwich layer of the frustum 100. Similarly, the shock-absorbing spring 650 can also be provided at the end of the frustum 100 or inside the frustum 100. The specific implementation manner is not unique, but can be adjusted according to the actual situation and is not limited here.

[0038] In some embodiments, referring to Figure 3 , a wear-resistant plate 630 is provided at the end of the shock-absorbing spring 650, and the shock-absorbing spring 650 contacts the frustum 100 and / or the shock-absorbing plate 300 through the wear-resistant plate 630. When the shock-absorbing plate 300 or the frustum 100 is subjected to the impact of the raw material on it, phenomena such as shaking or moving may easily occur, and the shock-absorbing plate 300 and the frustum 100 will be worn due to friction. The wear-resistant plate 630 can effectively reduce the wear phenomenon caused by friction, and thus effectively improve the service life of the decompression cone.

[0039] Specifically, wear-resistant plates 630 are provided at both ends of the shock-absorbing spring 650, and both ends of the shock-absorbing spring 650 contact the frustum 100 and the shock-absorbing plate 300 through the wear-resistant plates 630 respectively.

[0040] In some embodiments, referring to Figure 2 , the diversion structure 500 includes a plurality of through holes 150 penetrating the frustum 100. The through holes 150 penetrate the shock-absorbing plate 300 and are misaligned with the wear-resistant plate 630 and the shock-absorbing spring 650. The misalignment effect between the through holes 150 and the wear-resistant plate 630 and the shock-absorbing spring 650 can effectively avoid the problem that when the raw material moves through the through holes 150, it moves to the wear-resistant plate 630 and the shock-absorbing spring 650 by mistake, and thus the operation of the shock-absorbing spring 650 can be avoided from being disturbed. Therefore, the working stability of the wear-resistant plate 630 and the shock-absorbing spring 650 can be effectively improved.

[0041] In some embodiments, referring to Figure 2, a support rod 700 is provided at the bottom of the frustum 100. The support rod 700 can lift the frustum 100 from the support surface of the silo, thereby expanding the gap between the bottom of the frustum 100 and the bottom of the silo and avoiding the problem of raw materials being blocked in the gap between the bottom of the frustum 100 and the bottom of the silo.

[0042] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification.

[0043] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments, and various changes can be made without departing from the gist of the present invention within the knowledge scope of those of ordinary skill in the art.
