The paving device 10 includes a plurality of first bearing plates 200 and a plurality of second bearing plates 300, when the furnace body 100 is cylindrical, the first bearing plates 200 and the second bearing plates 300 may be circular, the first bearing plates 200 and the second bearing plates 300 are sequentially and alternately disposed in the reaction chamber 110 from top to bottom, that is, along the height direction of the furnace body 100, the plurality of first bearing plates 200 and the plurality of second bearing plates 300 are sequentially and alternately disposed in the reaction chamber 110. Specifically, the present invention may be the arrangement of a first carrier board 200, a second carrier board 300, a first carrier board 200, and a second carrier board 300, and further, may be the arrangement of a second carrier board 300, a first carrier board 200, a second carrier board 300, and a first carrier board 200, and a projection of the first carrier board 200 along a vertical direction falls on the second carrier board 300, and an edge of the projection of the first carrier board 200 and an edge of the second carrier board 300 are arranged at an interval, that is, an area of the first carrier board 200 is smaller than an area of the second carrier board 300, the second carrier board 300 can completely receive a material dropped on the first carrier board 200, the second carrier board 300 is further provided with a through hole 310, and an edge of the through hole 310 is located in the projection of the first carrier board 200, wherein the through hole 310 may be arranged at a middle position of the second carrier board 300, so that an unnecessary material can be transferred from the second carrier board 300 on an upper layer to the first carrier board 200 on a lower layer by the second scraper 530 from the through hole 310;

the driving mechanism 500 includes a driving member, a shaft 510, a plurality of first scrapers 520 and a plurality of second scrapers 530, and in the height direction of the furnace body 100, each of the first scrapers 520 is disposed above one of the first bearing plates 200 at an interval, that is, a set interval is provided between the first scrapers 520 and the first bearing plates 200, it is conceivable that the interval may determine the thickness of the laid materials, such that the thickness of the materials satisfies a reaction area of a gas phase reaction, for example, 30mm to 50mm, when the interval is exceeded, the first scrapers 520 may scrape the excessive materials onto the second bearing plates 300, and each of the second scrapers 530 is disposed above one of the second bearing plates 300 at an interval, that is, a set interval is provided between the second scrapers 530 and the second bearing plates 300, it is conceivable that the interval may determine the thickness of the laid materials, and when the interval is exceeded, the second scrapers 530 may scrape the excessive materials onto the first bearing plates 200; the first scrapers 520 and the second scrapers 530 are connected to the shaft 510, and the driving member can drive the shaft 510 to rotate, so that the shaft 510 drives the first scrapers 520 and the second scrapers 530 to rotate.

Specifically, after the plurality of first bearing plates 200 and the plurality of second bearing plates 300 are alternately arranged, the material enters from the material inlet 120, and then the material is stacked on the first bearing plate 200 on the upper layer, at this time, the first scraper 520 rotates to scrape the material on the first bearing plate 200 on the upper layer onto the second bearing plate 300 on the lower layer, and the material drops onto the second bearing plate 300 from the edge of the first bearing plate 200, it is conceivable that, in order to make the material drop from the edge of the first bearing plate 200, the first scraper 520 is arranged below the high temperature alloy steel rod, wherein the high temperature alloy steel rod may also be a connecting rod shaft, and then the first scraper 520 is inclined with respect to the steel rod, that is, when the first scraper 520 rotates, the inclined arrangement can better scrape the material off from the edge of the first bearing plate 200, that is, the material is pushed outwards when the first scraper 520 rotates. Then, the second scraper 530 scrapes off the materials on the second carrier 300, when too much materials are stacked on the second carrier 300, the second scraper 530 rotates to transfer the materials on the upper second carrier 300 to the lower first carrier 200 through the through holes 310, and then the first scraper 520 scrapes off the materials on the first carrier 200. It is contemplated that the second scraper 530 is disposed under the steel rod in order to make the material fall from the through hole 310 of the second loading plate 300, and then the second scraper 530 is inclined with respect to the steel rod, that is, the inclined arrangement can better scrape the material off the through hole 310 of the second loading plate 300 when the second scraper 530 rotates, that is, the material is pushed inward toward the center of the second loading plate 300 when the second scraper 530 rotates. Thus, the materials can be deposited on the plurality of first carrier plates 200 and the plurality of second carrier plates 300 and then react; because a plurality of first bearing plates 200 and a plurality of second bearing plates 300 are arranged, the silicon monoxide can be produced on a large scale, and because the first scraper 520 and the second scraper 530 can transfer the piled materials, the materials cannot be piled too much, and the reaction effect is influenced. Thus, the material can have a larger reaction area. In this way, the installation device 10 not only allows a large reaction area for the material, but also allows large-scale production of silica.

In some embodiments, paving machine 10 further comprises a pump connected to outlet 130 to generate gaseous silica when the materials react, so that the gaseous silica can be sucked to the deposition plate for crystallization by sucking air from the pump.

In some embodiments, the bottom of the first scraper 520 is provided with a protective film, and when the first scraper 520 and the first loading plate 200 are accidentally contacted, the protective film can prevent the first scraper 520 from scratching the first loading plate 200, thereby increasing impurities in the material.

In some embodiments, the bottom of the second scraper 530 is provided with a protective film, and when the second scraper 530 and the second loading plate 300 are accidentally contacted, the protective film can prevent the second scraper 530 from scratching the second loading plate 300, thereby increasing impurities in the material.

Referring to FIG. 1, in some embodiments, the axis of the throat 120 is collinear with the axis of the shaft 510, the shaft 510 includes a body portion 511 and a protrusion portion 512, the body portion 511 is connected to the first scraper 520 and the second scraper 530, the protrusion portion 512 is connected to the top end of the body portion 511, and the protrusion portion 512 is conical in shape. Specifically, after the material enters from the material inlet 120, the material drops onto the shaft 510, i.e., the protrusion 512. Since the protrusion 512 is conical, the material first contacts the top of the cone and then falls from the edge of the cone onto the first carrier plate 200. I.e., the material enters the shaft 510 and then reaches the center of the first carrier plate 200, and the material is transferred from the center to the edge by the first scraper 520. Due to the design of the conical protrusion 512, the materials can be uniformly distributed around the first loading board 200, and the first scraper 520 can further transfer the materials to each corner of the first loading board 200. More specifically, after the material enters the reaction chamber 110, the material can be distributed at two ends of the first loading plate 200, so that the dispersion efficiency is higher and the time is saved compared with the case that the material is distributed at one end of the first loading plate 200.

Referring to fig. 1, in some embodiments, the feed port 120 is disposed at the center of the top of the furnace body 100. Therefore, after the material enters from the material inlet 120, the material can fall to the middle position of the first loading plate 200.

Specifically, since the excessive material is first dropped from the edge of the first loading plate 200 and thus falls on the second loading plate 300, the excessive material is transferred from both sides of the dropping point by the second scraper 530. If the excessive material falls from the edge of the second loading plate 300, rather than the excessive material falling from the through hole 310 onto the first loading plate 200, there is no means under the second loading plate 300 to receive the material when the excessive material falls from the edge of the second loading plate 300 because the area of the second loading plate 300 is larger than that of the first loading plate 200, and the excessive material directly falls into the bottom of the reaction chamber 110. In the past, redundant materials are accumulated at the bottom of the reaction chamber 110, the reaction effect is poor, and the purity of the silicon monoxide is poor indirectly. Therefore, referring to fig. 1, in some embodiments, the paving device 10 further includes a baffle 400, a bottom end of the baffle 400 is connected to an outer edge of the second carrier 300, the baffle 400 surrounds the second carrier 300, and the baffle 400 protrudes from an upper surface of the second carrier 300. Thus, the baffle 400 can prevent the material from falling off the edge of the second loading plate 300.

Referring to fig. 1, in some embodiments, the height of the baffle 400 is not less than the distance between the second carrier 300 and the second scraper 530. Specifically, the distance between the second loading plate 300 and the second scraper 530 may be a thickness where the material is just completely reacted, and the height of the baffle 400 is greater than or equal to the distance between the second loading plate 300 and the second scraper 530 in order to prevent the material from falling off the edge of the second loading plate 300.

Referring to fig. 1, in some embodiments, the furnace body 100 has a collection port 140, the collection port 140 is connected to the reaction chamber 110, and the collection port 140 is disposed on the bottom wall of the reaction chamber 110. Specifically, it is contemplated that after the reaction of the materials, there will be a portion of the remaining material, commonly referred to as waste residue, that remains in the reaction chamber 110 to affect the reaction of the next batch of materials. A collection port 140 may be provided in the bottom wall of the reaction chamber 110 to collect the slag.

Further, to facilitate collection of the debris by the worker, referring to fig. 4, in some embodiments, the driving mechanism 500 includes a third scraper 540. The third scraper 540 is connected to the shaft 510 along the height direction of the furnace body 100, and the third scraper 540 is disposed above the bottom of the reaction chamber 110. Specifically, the materials are left on the bottom of the reaction chamber 110 after the reaction, and then the slag may be scraped into the collection port 140 by the third scraper 540, so that the slag is discharged from the collection port 140.

Referring to fig. 1, in some embodiments, the reaction chamber 110 is provided with a mounting hole 150, the shaft 510 is disposed through the mounting hole 150, such that a portion of the shaft 510 is located in the reaction chamber 110, and another portion of the shaft 510 is exposed out of the reaction chamber 110, and the driving member includes a first motor rotatably connected to the shaft 510. Specifically, the first motor is disposed outside the furnace body 100 and rotatably connected to the shaft 510, so that the shaft 510 drives the first scrapers 520 and the second scrapers 530 to rotate, and the materials are sequentially transferred from the top to the bottom of the reaction chamber 110, so that the reaction chamber 110 can accommodate more materials and have a larger reaction area.

In some embodiments, the first supporting plate 200 and the second supporting plate 300 are fixedly connected to the wall of the reaction chamber 110, and the paving device 10 further includes a lifting mechanism for driving the furnace body 100 to ascend or descend along its height direction. That is, the worker can control the elevating mechanism to raise or lower the reaction chamber 110 of the furnace body 100, thereby controlling the thickness of the paving material and the cleaning of the waste. Specifically, the first bearing plate 200 and the second bearing plate 300 are fixedly connected to the cavity wall of the reaction chamber 110, for example, a plurality of steel rods are connected to the lower portion of the first bearing plate 200, and the other end of the steel rods is connected to the cavity wall of the reaction chamber 110, so that when the furnace body 100 is driven by the lifting mechanism to ascend, the first bearing plate 200 and the second bearing plate 300 can ascend along with the furnace body 100. By the ascent of the furnace body 100, the interval between the first loading plate 200 and the first scraper 520, and the interval between the second loading plate 300 and the second scraper 530 can be changed. Thus, the thickness of the material placed on the first loading plate 200 and the second loading plate 300 can be indirectly changed. Furthermore, the thickness of the material can be conveniently adjusted by workers, so that the material achieves the best effect. It is conceivable that the interval between the first carrying plate 200 and the first scraper 520 and the interval between the second carrying plate 300 and the second scraper 530 become smaller as the furnace body 100 ascends, and at the same time, the interval between the third scraper 540 and the bottom of the reaction chamber 110 also becomes smaller. The first scraper 520, the second scraper 530 and the third scraper 540 can scrape the waste residue after reaction and transfer the waste residue to the collection port 140, so as to discharge the waste residue out of the reaction chamber 110.

In some embodiments, the lift mechanism comprises: the furnace body 100 comprises a base, a screw rod nut and a second motor, wherein the screw rod nut is connected to the bottom of the furnace body 100, the screw rod is connected to the screw rod nut, the second motor and the screw rod are arranged on the base, the second motor is rotatably connected to the screw rod, and the second motor can drive the screw rod to rotate so that the screw rod drives the screw rod nut to ascend or descend along the height direction of the furnace body 100. Specifically, after the second motor drives the furnace body 100 to ascend, the first bearing plate 200 moves towards the first scraper 520 to reduce the distance between the first bearing plate 200 and the first scraper 520, so that the thickness of material deposition is reduced, wherein the second bearing plate 300 and the second scraper 530 are also the same.

In some embodiments, the lifting mechanism further comprises a gear box and a lifter, the second motor is connected to the gear box, the gear box and the lifter are connected to the lead screw, the lead screw is connected to the lead screw nut, the second motor drives the gear box to rotate, and the lifter can have a turbine mechanism, namely the second motor is connected with the gear, the gear is connected with the turbine, and the turbine is rotatably connected with the lead screw. Therefore, the second motor can be rotatably connected with the screw rod, so that the screw rod rotates and drives the screw rod nut to ascend or descend.

In some embodiments, the lifting mechanism further comprises a bottom plate, the bottom plate is disposed between the screw nut and the furnace body 100, and the bottom plate plays a role of receiving the furnace body 100, so that a plurality of screw rods and a plurality of screw nuts can be disposed, and the plurality of screw nuts are connected to the bottom plate, thereby ensuring that the lifting mechanism can stably enable the furnace body 100 to ascend or descend.

In some embodiments, the lifting mechanism is disposed at a side portion of the furnace body 100, and the lifting mechanism includes a lead screw, a lead screw nut, and a second motor, the lead screw nut is connected to a side wall of the furnace body 100, the lead screw is connected to the lead screw nut, the second motor is rotatably connected to the lead screw, and the second motor can drive the lead screw to rotate, so that the lead screw drives the lead screw nut to move up or down along a height direction of the furnace body 100.

Further, the shaft 510 can drive the first scraper 520 to rotate when rotating by itself through the keyway connection, and then when waste slag is treated, because the temperature in the furnace body 100 is high, the first scraper 520 or the first bearing plate 200 can be heated to expand, and the distance between the first scraper 520 and the first bearing plate 200 is not easy to calculate, therefore, when the furnace body 100 is lifted by the lifting mechanism, the distance between the first scraper 520 and the first bearing plate 200 is reduced, and in order to avoid the damage caused by mutual scraping between the first scraper 520 and the first bearing plate 200 when the first scraper 520 rotates, the first scraper 520 can be lifted along with the first bearing plate 200 after contacting the first bearing plate 200 by the keyway connection. Specifically, the keyway connection can avoid damage from scraping between the first scraper 520 and the first carrier plate 200, as compared to the fixed connection of the first scraper 520 to the shaft 510.

Referring to fig. 7, in particular, the upper end of the second key 560 is disposed in the third key groove 531, and the lower end of the second key 560 is disposed in the fourth key groove 512, so that the second scraper 530 is movably connected to the shaft 510 through the key-and-groove connection. Further, the shaft 510 can drive the second scraper 530 to rotate when rotating through the keyway connection, and then when waste slag is treated, because the temperature in the oven body 100 is high, the second scraper 530 or the second bearing plate 300 can be heated and expanded, and the distance between the second scraper 530 and the second bearing plate 300 is not well calculated, therefore, when the oven body 100 is lifted by the lifting mechanism, the distance between the second scraper 530 and the second bearing plate 300 is reduced, and in order to avoid mutual scratch and damage between the second scraper 530 and the second bearing plate 300 when the second scraper 530 rotates, the keyway connection can make the second scraper 530, after contacting the second bearing plate 300, lift along with the second bearing plate 300. Specifically, compared to the fixed connection of the second scraper 530 to the shaft 510, the keyway connection can prevent the second scraper 530 and the second loading plate 300 from being damaged by rubbing. The first key 550 and the second key 560 may be a flat key, a semicircular key, a spline, or the like.
