Description

Technical Field

[0001] The present application relates to the technical field of belt separation equipment, and in particular to a mesh belt joint, an annular mesh belt, a hot pressing link device and a belt separation equipment. Background Art

[0002] In the filtration and separation industries such as solid-liquid separation, solid-gas separation, gas-liquid separation, etc., the commonly used equipment includes belt filter press, belt vacuum filter or dryer and other separation equipment. These equipments need to use annular media, that is, annular mesh belts. The annular mesh belt includes a belt mesh belt and a mesh belt joint; the mesh belt joint is used to connect the belt mesh belt into a ring.

[0003] In traditional belt-type equipment such as filtering and drying, Figure 1 As shown, the mesh belt joint 100 generally includes a first metal steel buckle 110, a second metal steel buckle 120 and a metal through-core 130. The first metal steel buckle 110 is connected to the first end mesh belt segment 210 of the belt mesh belt, and the second metal steel buckle 120 is connected to the second end mesh belt segment 220 of the belt mesh belt. The first metal steel buckle 110 and the second metal steel buckle 120 are overlapped, and the metal through-core 130 is inserted into the inner side of the first metal steel buckle 110 and the second metal steel buckle 120 to limit the first metal steel buckle 110 and the second metal steel buckle 120.

[0004] In this regard, since the first metal steel buckle 110 and the second metal steel buckle 120 are both metal rigid structures, while the mesh belt itself is a soft structure. Therefore, the belt mesh belt is relatively easy to deform during use, while the first metal steel buckle 110 and the second metal steel buckle 120 are not deformed, which causes the critical position where the belt mesh belt and the metal steel buckle are combined to become a stress concentration point, and the annular mesh belt is easy to bulge, deform, and even be damaged at this position, thereby seriously affecting the service life of the annular mesh belt. In addition, the existing mesh belt joint 100 is a metal joint, which is not resistant to strong acid and alkali corrosion under many harsh working conditions and has an extremely short service life.

[0005] Therefore, how to improve the mesh belt joint to increase the service life of the endless mesh belt is still a technical problem that technical personnel in this field need to solve urgently. Utility Model Content

[0006] In view of this, in order to solve the above-mentioned technical problems, the present application provides a mesh belt joint, an annular mesh belt, a hot pressing welding device and a belt separation equipment.

[0007] In order to solve the above technical problems, one of the technical solutions adopted by the present application is to provide a mesh belt joint, which is used in a belt mesh belt, and the belt mesh belt has a first direction and a second direction perpendicular to each other; the mesh belt joint is used to connect the belt mesh belt so that the belt mesh belt is annular along the first direction;

[0008] The mesh belt joint includes a first end mesh belt segment and a second end mesh belt segment which are stacked; a plurality of hot pressing welding areas are formed between the first end mesh belt segment and the second end mesh belt segment; the first end mesh belt segment and the second end mesh belt segment in the area corresponding to the hot pressing welding area are hot pressing welded, and the plurality of hot pressing welding areas are arranged at intervals along the first direction of the mesh belt.

[0009] In order to solve the above-mentioned technical problems, another technical solution adopted in the present application is to provide an annular mesh belt, which includes a belt mesh belt, and the belt mesh belt has a first direction and a second direction perpendicular to each other; the belt mesh belt includes a first end mesh belt segment, a functional mesh belt and a second end mesh belt segment connected in sequence along the first direction; the first end mesh belt segment and the second end mesh belt segment form a mesh belt joint, and the mesh belt joint is the above-mentioned mesh belt joint.

[0010] In order to solve the above technical problems, another technical solution adopted by the present application is to provide a hot pressing welding device, which is used to prepare the above-mentioned endless mesh belt, and the hot pressing welding device includes:

[0011] A wedge-shaped heating element is provided with a plurality of pairs of heat-conducting protrusions, and the plurality of pairs of heat-conducting protrusions are arranged at intervals along the left-right direction of the hot pressing welding device; each pair of heat-conducting protrusions comprises an upper heat-conducting protrusion arranged on the upper surface of the wedge-shaped heating element and a lower heat-conducting protrusion arranged on the lower surface of the wedge-shaped heating element; the upper heat-conducting protrusion is used to heat the mesh belt section at the first end; and the lower heat-conducting protrusion is used to heat the mesh belt section at the second end;

[0012] And a rolling assembly is arranged on the front side of the wedge-shaped heating element, which is used to roll the first end mesh belt segment and the second end mesh belt segment after being heated by the wedge-shaped heating element, so that the first end mesh belt segment and the second end mesh belt segment form the above-mentioned mesh belt joint.

[0013] In order to solve the above technical problems, another technical solution adopted by the present application is to provide a belt-type separation device, which is used to separate the first substance and the second substance in the mixture; the belt-type separation device comprises:

[0014] A first roller and a second roller, wherein the first roller and the second roller are spaced apart from each other to form a preset spacing space between the first roller and the second roller;

[0015] An annular mesh belt is arranged in a preset interval and connected to the first roller and the second roller respectively, and the annular mesh belt is the annular mesh belt mentioned above; the annular mesh belt can intercept the first substance and allow the second substance to separate, so that the second substance can be separated from the upper side or the lower side of the belt mesh belt;

[0016] And a driving device is used for driving the first roller and / or the second roller to rotate, so as to drive the belt mesh belt to move along the circumferential direction of the annular mesh belt between the first roller and the second roller.

[0017] Beneficial effects: Different from the prior art, the technical solution of the present application can at least improve the service life of the annular mesh belt from the following three aspects.

[0018] First, in the annular mesh belt of the present application, since the material forming the mesh belt joint is the material of the belt mesh belt itself, the stress at the critical position where the mesh belt joint is combined with the functional mesh belt can be reduced, thereby reducing the probability of damage to the mesh belt at this position. That is, compared with the existing annular mesh belt, the annular mesh belt of the present application has a longer service life.

[0019] On the second aspect, in the annular mesh belt of the present application, multiple hot pressing welding areas are arranged at intervals along the first direction of the belt mesh belt, which can form layered seams between adjacent hot pressing welding areas. In this way, compared with the hot pressing welding areas, the mesh belt joints in the areas corresponding to the layered seams are formed into relatively soft and easily flexibly deformed areas. Therefore, compared with the existing annular mesh belts, in the annular mesh belt of the present application, the flexibility of the mesh belt joints can be improved by alternating the hot pressing welding areas and the layered seams, and the stress at the critical position where the mesh belt joints are combined with the functional mesh belt can be reduced. Furthermore, compared with the existing annular mesh belts, the annular mesh belt of the present application has a longer service life.

[0020] Thirdly, compared with the metal joints used in the original technical solution, in many harsh working conditions with strong acid, strong alkali and high chloride ion content, ordinary metal materials are completely unable to withstand corrosion and have a very short service life. Even if the existing mesh belt joints are made of 316L stainless steel or even Hastelloy alloy, they still cannot withstand corrosion for a long time and are damaged. In the technical solution of this application, the material of the mesh belt joint is the material of the belt mesh belt itself, which has a high degree of corrosion resistance, thereby extending the service life of the ring mesh belt.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the technical solution of the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described implementation methods are only part of the implementation methods of the present application, rather than all the implementation methods. Based on the implementation methods in the present application, all other implementation methods obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0035] See also Figure 2 The belt-type separation device of the present application is used to separate a mixture, wherein the mixture includes a first substance and a second substance. The belt-type separation device 300 includes a first roller 310 , a second roller 320 , an endless mesh belt 330 and a driving device 340 .

[0036] The first roller 310 and the second roller 320 are arranged at intervals to form a preset interval space 301 between the first roller 310 and the second roller 320. The endless mesh belt 330 is arranged in the preset interval space 301 and is connected to the first roller 310 and the second roller 320 respectively. The driving device 340 is used to drive the first roller 310 and / or the second roller 320 to rotate, so as to drive the endless mesh belt 330 to move between the first roller 310 and the second roller 320 along the circumferential direction of the endless mesh belt 330. The endless mesh belt 330 can intercept the first substance and allow the second substance to be separated.

[0037] By way of example and not limitation, the first substance and the second substance are described below using three examples.

[0038] In a first example, the first substance may be a solid state and the second substance may be a liquid state. In a second example, the first solid state may be a solid state and the second substance may be a gaseous state. In a third example, the first substance may be a liquid state and the second substance may be a gaseous state.

[0039] Furthermore, if Figure 2 As shown, the first substance is solid and the second substance is gaseous or liquid. The belt separation device 300 includes a scraper 350. The scraper 350 is arranged corresponding to the first roller 310 and / or the second roller 320 and contacts the endless mesh belt 330. The scraper 350 is used to scrape off the first substance trapped by the endless mesh belt 330.

[0040] Furthermore, combined with Figure 2 See also Figure 3 and Figure 4 The endless mesh belt 330 includes a belt mesh belt 10, which has a first direction L and a second direction W that are perpendicular to each other. The belt mesh belt 10 includes a first end mesh belt segment 11, a functional mesh belt 12, and a second end mesh belt segment 13 that are sequentially connected along the first direction L.

[0041] The first end mesh belt segment 11 and the second end mesh belt segment 13 form a mesh belt joint 14, so that the functional mesh belt 12 and the mesh belt joint 14 are enclosed in a ring. The mesh belt joint 14 includes the first end mesh belt segment 11 and the second end mesh belt segment 13 being stacked, and a plurality of hot pressing welding areas 14-1 are formed between the first end mesh belt segment 11 and the second end mesh belt segment 13. The first end mesh belt segment 11 and the second end mesh belt segment 13 are hot pressed and welded in the corresponding area of ​​the hot pressing welding area 14-1, and the plurality of hot pressing welding areas 14-1 are arranged at intervals along the first direction L of the belt mesh belt 10. The second material is separated from the upper side or the lower side of the belt mesh belt 10.

[0042] By comparing the above methods, Figure 1 Combination Figure 2 See also Figure 3 and Figure 4 The technical solution of the present application can at least improve the service life of the annular mesh belt 330 from the following three aspects.

[0043] First, in the annular mesh belt of the present application, since the material forming the mesh belt joint 14 is the material of the belt mesh belt 10 itself, the stress at the critical position where the mesh belt joint 14 is combined with the functional mesh belt 12 can be reduced, thereby reducing the probability of damage to the annular mesh belt 330 at this position. That is, compared with the existing annular mesh belt, the annular mesh belt 330 of the present application has a longer service life.

[0044] On the second aspect, in the annular mesh belt of the present application, a plurality of hot pressing welding areas 14-1 are arranged at intervals along the first direction L of the belt mesh belt 10, so that a strip-shaped layered seam 14-2 can be formed between adjacent hot pressing welding areas 14-1. Therefore, compared with the hot pressing welding area, the mesh belt joint 14 in the area corresponding to the strip-shaped layered seam 14-2 is formed into a relatively soft area that is easy to deform flexibly. Therefore, compared with the existing annular belt, in the annular mesh belt 330 of the present application, the alternating arrangement of the hot pressing welding area 14-1 and the strip-shaped layered seam 14-2 can improve the flexibility of the mesh belt joint 14 and reduce the stress at the critical position of the mesh belt joint 14 and the functional mesh belt 12. Furthermore, compared with the existing annular mesh belt, the annular mesh belt 330 of the present application has a higher service life.

[0045] Thirdly, compared with the mesh belt joint 100 in the prior art solution, which uses a metal joint, in many harsh working conditions with strong acid, strong alkali, and high chloride ion content, ordinary metal materials are completely unable to withstand corrosion and have a very short service life. Even if the mesh belt joint 100 is made of 316L stainless steel or even Hastelloy alloy, it still cannot withstand corrosion for a long time and is damaged. In the technical solution of this application, the material of the mesh belt joint 14 is the material of the belt mesh belt 10 itself, which has a high degree of corrosion resistance, thereby extending the service life of the annular mesh belt 330.

[0046] Preferably, the hot pressing welding area 14-1 extends into a strip shape along the second direction W of the belt mesh belt 10. This is beneficial to increase the connection strength of the mesh belt joint 14, so that the mesh belt joint 14 can resist a greater pulling force without breaking.

[0047] Optionally, the material of the belt mesh belt 10 includes but is not limited to thermoplastic material, for example, including but not limited to at least one of PP (polypropylene), PET (polyethylene terephthalate) and PPS (polyphenylene sulfide).

[0048] Optionally, the belt mesh belt 10 has a third direction H, which is the stacking direction of the first end mesh belt segment 11 and the second end mesh belt segment 13. The thickness of the mesh belt joint 14 in the third direction H is a first dimension a, which is greater than 0 mm and not greater than 10 mm.

[0049] Specifically, combined Figure 2 See also Figure 3 If the mesh belt joint 14 is too thick, it will affect the flexibility of the mesh belt joint 14, while if the mesh belt joint 14 is too thin, it will affect the filtering performance and the connection strength of the hot pressing welding. Therefore, the first dimension a can be greater than 0 mm and not greater than 10 mm (for example, 2 mm, 5 mm, 10 mm) to take into account the flexibility of the mesh belt joint 14, the filtering performance and the connection strength of the hot pressing welding area.

[0050] Preferably, combined Figure 2 See also Figure 3 The size of the mesh belt joint 14 in the first direction L is a second size b, which is not less than 10 mm and not more than 300 mm (for example, 10 mm, 30 mm, 50 mm, 100 mm, 200 mm, 300 mm), but is not limited thereto. Further, the second size b is not less than 10 mm and not more than 200 mm, but is not limited thereto.

[0051] It should be noted that, in other examples, the first dimension a may be greater than 10 mm, or the second dimension b may be less than 10 mm, or the second dimension b may be greater than 200 mm. That is, the dimensions may be designed according to specific needs.

[0052] Furthermore, combined with Figure 1 See also Figure 2 The first end mesh belt segment 11 is located on the outer ring side, and the second end mesh belt segment 13 is located on the inner ring side. The end of the first end mesh belt segment 11 that is not integrally connected with the functional mesh belt 12 is correspondingly stacked on the end of the second end mesh belt segment 13 that is integrally connected with the functional mesh belt 12.

[0053] The direction of the end of the first end mesh belt segment 11 that is not integrally connected with the functional mesh belt 12 is the fourth direction S1; the direction of the end of the scraper 350 close to the belt mesh belt 10 is the fifth direction S2. When the end of the first end mesh belt segment 11 that is not integrally connected with the functional mesh belt 12 moves to the minimum distance from the end of the scraper 350 close to the belt mesh belt 10, the angle between the fourth direction S1 and the fifth direction S2 is less than 90 degrees.

[0054] Through the above method, the scraper 350 is not easily stuck with the end surface of the first end mesh belt segment 11 that is not integrally connected with the functional mesh belt 12, so that the end surface of the first end mesh belt segment 11 that is not integrally connected with the functional mesh belt 12 can pass through the scraper 350 more easily.

[0055] The present application also provides a mesh belt joint, which is the same as the above-mentioned mesh belt joint 14 and will not be described in detail here.

[0056] See also Figure 5 and Figure 6 The present application also provides a hot pressing welding device 400 , which is used to prepare the above-mentioned annular mesh belt 330 . The hot pressing welding device 400 includes a wedge-shaped heating element 410 and a rolling assembly 420 .

[0057] The wedge-shaped heating element 410 is provided with a plurality of pairs of heat-conducting protrusions 430, and the plurality of pairs of heat-conducting protrusions 430 are arranged at intervals along the left-right direction of the hot pressing welding device 400. Each pair of heat-conducting protrusions 430 includes an upper heat-conducting protrusion 431 provided on the upper surface of the wedge-shaped heating element 410 and a lower heat-conducting protrusion 432 provided on the lower surface of the wedge-shaped heating element 410. The upper heat-conducting protrusion 431 is used to heat the first end mesh belt segment 11. The lower heat-conducting protrusion 432 is used to heat the second end mesh belt segment 13. The rolling assembly 420 is provided at the front side of the wedge-shaped heating element 410, and is used to roll the first end mesh belt segment 11 and the second end mesh belt segment 13 after being heated by the wedge-shaped heating element 410, so that the first end mesh belt segment 11 and the second end mesh belt segment 13 form a mesh belt joint 14.

[0058] Specifically, when the wedge-shaped heating element 410 heats the first end mesh belt segment 11 and the second end mesh belt segment 13, the bottom surface of the first end mesh belt segment 11 is in surface contact with the upper heat-conducting protrusion 431, so that the material in contact with the bottom surface of the first end mesh belt segment 11 and the upper heat-conducting protrusion 431 is heated and becomes molten; and the top surface of the second end mesh belt segment 13 is in surface contact with the lower heat-conducting protrusion 432, so that the material in contact with the top surface of the second end mesh belt segment 13 and the lower heat-conducting protrusion 432 is heated and becomes molten. When the rolling assembly 420 rolls the first end mesh belt segment 11 and the second end mesh belt segment 13 heated by the wedge-shaped heating element 410, the area of ​​the first end mesh belt segment 11 that was previously in contact with the upper heat-conducting protrusion 431 is further pressed and cooled with the area of ​​the second end mesh belt segment 13 that was previously in contact with the lower heat-conducting protrusion 432, so that the melted portion of the area of ​​the first end mesh belt segment 11 that was previously in contact with the upper heat-conducting protrusion 431 and the melted portion of the area of ​​the second end mesh belt segment 13 that was previously in contact with the lower heat-conducting protrusion 432 are connected into one and cooled and solidified, thereby achieving a hot pressing welding effect.

[0059] Optionally, combined Figure 5 See also Figure 6 , the heat-conducting protrusion 430 extends into a strip shape along the front-to-back direction of the hot pressing welding device 400. Further, the front end of the upper heat-conducting protrusion 431 extends along the front end contour of the upper surface of the wedge-shaped heating element 410, and the front end of the lower heat-conducting protrusion 432 extends along the front end contour of the lower surface of the wedge-shaped heating element 410, and the front end of the upper heat-conducting protrusion 431 and the front end of the lower heat-conducting protrusion 432 are connected to form an integral structure. In this way, by extending the front end of the upper heat-conducting protrusion 431 and the front end of the lower heat-conducting protrusion 432 along the front end contour of the wedge-shaped heating element 410 and connecting them to form an integral structure, the first end mesh belt segment 11 and the second end mesh belt segment 13 can be guided to the rolling assembly 420 more accurately and smoothly.

[0060] By way of example and not limitation, Figure 5 and Figure 6 As shown in FIG. 3C , a heating rod 411 is disposed inside the wedge-shaped heating element 410 so that the wedge-shaped heating element 410 can achieve a heating function.

[0061] Furthermore, combined with Figure 5 and Figure 6 See also Figure 7 The hot press welding device 400 includes an upper shell 440 and a lower shell 450. The upper shell 440, the wedge-shaped heating element 410 and the lower shell 450 are arranged in sequence from top to bottom. The first side is one of the left side and the right side, and the second side is the other of the left side and the right side.

[0062] The first side of the upper shell 440 is connected to the first side of the wedge-shaped heating element 410, and the second side of the upper shell 440 is spaced apart from the second side of the wedge-shaped heating element 410 to form a first groove 401 between the upper shell 440 and the wedge-shaped heating element 410. The first groove 401 is used to receive the first end mesh belt segment 11 inserted from the second side of the hot pressure welding device 400.

[0063] The second side of the lower shell 450 is connected to the second side of the wedge-shaped heating element 410, and the first side of the lower shell 450 is separated from the first side of the wedge-shaped heating element 410 to form a second groove 402 between the lower shell 450 and the wedge-shaped heating element 410, and the second groove 402 is used to receive the second end mesh belt segment 13 inserted from the first side of the hot pressure welding device 400.

[0064] Through the above method, the first groove 401 can be used to facilitate the first end mesh belt segment 11 to be placed above the wedge-shaped heating element 410, and the second groove 402 can be used to facilitate the second end mesh belt segment 13 to be placed below the wedge-shaped heating element 410, and the heated first end mesh belt segment 11 and the second end mesh belt segment 13 can be conveniently moved forward to the rolling assembly 420.

[0065] Combined with the picture Figure 5 See also Figure 8 As shown, the rolling assembly 420 includes an upper driving pressing wheel 421 and a lower driving pressing wheel 422. The upper driving pressing wheel 421 and the lower driving pressing wheel 422 are arranged at intervals up and down to roll the first end mesh belt segment 11 and the second end mesh belt segment 13 passing between the upper driving pressing wheel 421 and the lower driving pressing wheel 422.

[0066] The first end is one of the left and right ends, and the second end is the other of the left and right ends. The first end of the upper driving pressure wheel 421 is provided with a first deviation correction thread 423, and the second end of the lower driving pressure wheel 422 is provided with a second deviation correction thread 424.

[0067] Among them, when the upper driving pressure wheel 421 and the lower driving pressure wheel 422 roll the first end mesh belt segment 11 and the second end mesh belt segment 13, the first correcting thread 423 has a correcting force on the first end mesh belt segment 11 toward the second end, and the second correcting thread 424 has a correcting force on the second end mesh belt segment 13 toward the first end.

[0068] Through the above-mentioned method, the first correcting thread 423 and the second correcting thread 424 can more accurately limit the stacked first end mesh belt segment 11 and the second end mesh belt segment 13, so that the stacked first end mesh belt segment 11 and the second end mesh belt segment 13 are not easy to deviate, and thus the manufactured annular mesh belt 330 is not easy to deviate under the drive of the first roller 310 and / or the second roller 320.

[0069] By way of example and not limitation, Figure 8 As shown, when observing the rolling assembly 420 from the rear side, the first correcting thread 423 extends from the side of the upper driving wheel 421 close to the lower driving wheel 422 to the side of the upper driving wheel 421 away from the lower driving wheel 422, and extends in the direction from the second end to the first end. Figure 8 As shown, observing the rolling assembly 420 from the rear side of the rolling assembly 420, the extension direction of the second correcting thread 424 is formed as: from the side of the lower driving pressure wheel 422 close to the upper driving pressure wheel 421 to the side of the lower driving pressure wheel 422 away from the upper driving pressure wheel 421, extending in the direction from the first end to the second end.

[0070] Optionally, combined Figure 5 See also Figure 8 The surface of the upper driving pressing wheel 421 and the surface of the lower driving pressing wheel 422 are provided with knurled anti-skid patterns 425. Thus, the knurled anti-skid patterns 425 can prevent the upper driving pressing wheel 421 from slipping with the first end mesh belt segment 11 and the lower driving pressing wheel 422 from slipping with the second end mesh belt segment 13 during the rolling process.

[0071] Furthermore, combined with Figure 5 See also Figure 8 The hot pressing welding device 400 includes an upper limit plate 460 and a lower limit plate 470 .

[0072] The upper limit plate 460 is disposed on the side of the rolling assembly 420 facing the wedge-shaped heating element 410, and includes a first support plate 461 and a first side limit plate 462. The first support plate 461 is used to support the first end mesh belt segment 11. The first side limit plate 462 is disposed on the first side of the first support plate 461 and extends upward, and is used to stop the first side of the first end mesh belt segment 11.

[0073] The lower limit plate 470 is arranged on the side of the rolling assembly 420 facing the wedge-shaped heating element 410, and includes a second support plate 471 and a second side limit plate 472. The second support plate 471 is used to support the second end mesh belt segment 13. The second side limit plate 472 is arranged on the second side of the second support plate 471 and extends upward to stop the second side of the first end mesh belt segment 11.
