Description

Technical Field

[0001] This utility model relates to the field of glass fiber waste recycling technology, and in particular to a negative pressure dehydration belt for glass fiber waste. Background Technology

[0002] Fiberglass waste is an unavoidable industrial tailings in fiberglass production. Directly burying it will cause serious pollution to the land and waste land resources. The recycling of fiberglass waste requires major steps such as crushing, draining, impurity removal, incineration, grinding, screening, packaging, and dust collection.

[0003] After the shredded fiberglass waste is rinsed in a rinsing machine, it contains a large amount of water, which is not conducive to the next step of incineration. It is usually dehydrated by a vacuum belt dewatering machine, and scrapers are used to scrape and collect the fragments adhering to the filter cloth on the surface of the negative pressure dewatering belt.

[0004] However, during the negative pressure dewatering process, the waste fiberglass filaments will get stuck in the pores of the filter cloth and will not be easily scraped off by the scraper, resulting in waste of raw materials. At the same time, the blocked pores of the filter cloth will also hinder the dewatering of the waste fiberglass filaments in the next cycle.

[0005] Therefore, a negative pressure dehydration belt for waste glass fiber is proposed. Utility Model Content

[0006] The purpose of this invention is to solve the problem in existing vacuum belt dewatering machines that fiberglass waste shreds become deeply embedded in the filter cloth pores during negative pressure dewatering, making them difficult to scrape off by the scraper, resulting in material waste. At the same time, the blocked filter cloth pores also hinder the dewatering of the next batch of fiberglass waste shreds. Therefore, a negative pressure dewatering belt for fiberglass waste shreds is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A negative pressure dewatering belt for waste glass fiber includes a negative pressure dewatering belt body and a dewatering filter cloth. The negative pressure dewatering belt body has negative pressure holes, and the dewatering filter cloth has dewatering holes adapted to the negative pressure holes. Inclined filter strips are fixed on the outer surface of the dewatering filter cloth. Multiple water guiding strips are fixed on the inner side of the negative pressure dewatering belt body, and a sealing strip is fixed on the outer edge of the inner side of the negative pressure dewatering belt body.

[0009] Preferably, the negative pressure hole is disposed between adjacent water guide strips, and the cross-section of the water guide strip is trapezoidal.

[0010] Preferably, the dehydration hole is inclined, and the side of the dehydration hole closest to the negative pressure dehydration belt body is connected to the negative pressure hole.

[0011] Preferably, the inclined filter strip is inclined, and the inclination direction is adapted to the inclination direction of the dewatering hole.

[0012] Preferably, the inclined filter bar has a filter arc surface on the side near the dewatering filter cloth, and the filter arc surface has a diagonal groove on the side near the dewatering filter cloth.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting up inclined filter strips and dewatering filter cloth in combination, the negative pressure at the dewatering holes is used to absorb the moisture from the waste glass fiber filaments. The inclined filter strips cover the dewatering holes to form a layered filtration structure, which prevents the waste filaments from entering the pores and prevents the waste filaments from sinking into the filter cloth. This makes it easier for the scraper to remove the waste filaments and reduces the waste of raw materials.

[0015] 2. By setting up water guide strips and sealing strips in combination, the negative pressure dewatering belt body forms a curved surface when passing through the scraper area. This will squeeze the rectangular space between the water guide strips and the sealing strips to generate positive air pressure, which will blow the glass fiber waste filaments between the dewatering holes and the inclined filter strips to the centralized collection point, further improving the recovery of glass fiber waste filaments.

[0016] 3. By setting up water guide strips and sealing strips in combination, a rectangular negative pressure area is formed, which can maximize the transmission of vacuum pump suction to the dewatering hole and prevent sewage from adhering to the inside of the vacuum belt and causing blockage.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 A negative pressure dewatering belt for waste glass fiber includes a negative pressure dewatering belt body 1 and a dewatering filter cloth 2. The negative pressure dewatering belt body 1 has a negative pressure hole 101, and the dewatering filter cloth 2 has a dewatering hole 201 that matches the negative pressure hole 101.

[0024] It should be noted that the negative pressure dewatering belt body 1 proposed in this utility model is installed on a vacuum belt dewatering machine. A scraper is provided on the vacuum belt dewatering machine to scrape off the glass fiber waste shreds on the filter cloth. This is the conventional mechanical setting of the vacuum belt dewatering machine. The vacuum dewatering process of the vacuum belt dewatering machine is feeding, preliminary dewatering, vacuum dewatering, filter belt cleaning, unloading and conveyor belt circulation. This is the operation process of the existing vacuum belt dewatering machine, and will not be repeated in the following description of the vacuum belt dewatering machine.

[0025] Based on the above, when the vacuum belt dewatering machine performs vacuum dewatering, a negative pressure is generated by a vacuum pump, and the water in the glass fiber waste filaments at the dewatering hole 201 is absorbed and filtered through the negative pressure hole 101.

[0026] like Figure 3 As shown, an inclined filter strip 3 is fixed on the outer surface of the dewatering filter cloth 2. The inclined filter strip 3 is inclined and the inclined direction is adapted to the inclined direction of the dewatering hole 201. The dewatering hole 201 is inclined and the side of the dewatering hole 201 near the negative pressure dewatering belt body 1 is connected to the negative pressure hole 101.

[0027] Furthermore, the inclined filter bar 3 has a filter arc surface on the side near the dewatering filter cloth 2, and the filter arc surface has a diagonal groove on the side near the dewatering filter cloth 2.

[0028] It should be noted that the dewatering filter cloth 2 only exerts suction on the glass fiber waste at the dewatering holes 201. When the glass fiber waste falls to the outside of the negative pressure dewatering belt body 1, the negative pressure at the dewatering holes 201 absorbs the water in the glass fiber waste. The inclined filter strips 3 pressed down on the dewatering holes 201 cover the dewatering holes 201, which can block the glass fiber waste entering the inclined dewatering holes 201. In the scraper area, the dewatering filter cloth 2 is scraped by the scraper to scrape the glass fiber waste sandwiched between the inclined filter strips 3, thereby avoiding the glass fiber waste from being trapped in the filter cloth pores during the negative pressure dewatering process and being unable to be scraped by the scraper, resulting in material waste.

[0029] The further advantage of using the above is that when the inclined filter bar 3 filters the glass fiber waste, the multiple inclined grooves can form a layered filtration structure to filter the moisture in the glass fiber waste, preventing the glass fiber waste from entering the dewatering hole 201 and getting stuck in the negative pressure hole 101, blocking the negative pressure hole 101, and hindering the dewatering of the glass fiber waste fragments in the next cycle.

[0030] Based on the above, when the dewatering filter cloth 2 follows the negative pressure dewatering belt body 1 through the filter belt cleaning area, the resistance of the water flow to the inclined filter strip 3 causes the inclined filter strip 3 to open outward, which facilitates the water flow to clean the impurities trapped between the inclined filter strip 3 and the dewatering filter cloth 2, thus achieving the effect of convenient cleaning of the dewatering filter cloth 2.

[0031] like Figure 1 and Figure 2 As shown, multiple water guide strips 4 are fixed inside the negative pressure dehydration belt body 1, and a sealing strip 5 is fixed on the outer edge of the inner side of the negative pressure dehydration belt body 1.

[0032] Furthermore, the negative pressure hole 101 is disposed between adjacent water guide strips 4, and the cross-section of the water guide strip 4 is set as trapezoidal.

[0033] It should be noted that when the negative pressure hole 101 generates negative pressure suction on the waste glass fiber, the water will drip down with the water guide strip 4 to the middle area of ​​the suction, so as to avoid the impurities mixed in the water droplets dripping down the negative pressure dehydration belt body 1 onto the surface of the vacuum mechanism of the vacuum belt dehydrator and causing blockage.

[0034] The further advantage of the above is that when a vacuum area is formed in the rectangular negative pressure area formed by the sealing strip 5 and the water guide strip 4, the suction force of the vacuum pump can be transmitted to the dewatering hole 201 to the maximum extent, avoiding sewage from adhering to the inner side of the vacuum belt and causing blockage. At the same time, when the sealing strip 5 and the water guide strip 4 form a curved surface through the scraper area, they squeeze the rectangular space formed by the two, generating positive air pressure flowing towards the dewatering hole 201. This blows air onto the glass fiber waste filaments between the dewatering hole 201 and the inclined filter strip 3, blowing them outwards to the centralized collection point, thereby achieving the effect of increasing the dewatering and recovery of glass fiber waste filaments.

[0035] Working principle:

[0036] When this utility model is in use, the negative pressure at the dewatering hole 201 absorbs the moisture from the glass fiber waste shreds. The inclined filter strip 3 pressed down on the dewatering hole 201 covers the dewatering hole 201, which can block the glass fiber waste shreds entering the inclined dewatering hole 201. In the scraper area, the scraper scrapes the dewatering filter cloth 2 and scrapes the glass fiber waste shreds sandwiched between the inclined filter strip 3, thereby avoiding the glass fiber waste shreds from being deeply trapped in the pores of the filter cloth during the negative pressure dewatering process and being unable to be scraped by the scraper, thus avoiding the waste of raw materials.

[0037] Based on the above, when a vacuum area is formed in the rectangular negative pressure area formed by the sealing strip 5 and the water guide strip 4, the suction force of the vacuum pump can be transmitted to the dewatering hole 201 to the maximum extent, avoiding sewage from adhering to the inner side of the vacuum belt and causing blockage. At the same time, when the sealing strip 5 and the water guide strip 4 pass through the scraper area and form a curved surface, they squeeze the rectangular space formed by the two, generating positive air pressure flowing towards the dewatering hole 201. This blows air onto the glass fiber waste between the dewatering hole 201 and the inclined filter strip 3, blowing it outwards to the centralized collection point, thereby achieving the effect of increasing the dewatering and recovery of glass fiber waste.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
