[0020] In order to make the purpose, technical solutions and advantages of the implementation methods of this application clearer, the technical solutions in the implementation methods of this application will be clearly and completely described below in conjunction with the drawings in the implementation methods of this application. Obviously, the described implementation methods are part of the implementation methods of this application, not all of the implementation methods. Based on the implementation methods in this application, all other implementation methods obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Embodiment 1, as Figure 1-Figure 14 As shown, according to an embodiment of the present application, a high-efficiency drying device for producing forsterite castables comprises a kiln 1, wherein both ends of the kiln 1 are respectively connected to a first high-pressure blower 2 for conveying gas outwardly and a second high-pressure blower 21 for conveying gas inwardly, wherein Figure 1 As shown, a track 11 is laid inside the kiln 1 along the depth direction of the kiln 1, and the formed forsterite castable slowly moves in the kiln 1 along the direction of the track 11. The upper side wind heating component 13 and the lower side wind heating component 12 are symmetrically arranged on both sides of the top and bottom of the track 11 inside the kiln 1, which are used to generate heat and use wind energy to blow the heat energy to the formed forsterite castable to dry the formed forsterite castable. The two ends of the kiln 1 are respectively a feed end 14 and a discharge end 15. Specifically, in the present application, the upper side wind heating component 13 and the lower side wind heating component 12 are prior arts, which can be achieved by electric heating in combination with a fan, and are not elaborated here.

[0022] like Figure 1 and Figure 2 As shown, the air outlet end of the first high-pressure blower 2 is connected to the air inlet cabin 3, and the air inlet cabin 3 is mounted on the kiln 1; the air inlet end of the second high-pressure blower 21 is connected to the air outlet cabin 4, and the air outlet cabin 4 is mounted on the kiln 1; a plurality of dehumidification mechanisms 5 are detachably connected between the air inlet cabin 3 and the air outlet cabin 4, wherein a dehumidification mechanism 5 is connected at the axis of the air inlet cabin 3 and the air outlet cabin 4, and a plurality of dehumidification mechanisms 5 are evenly arranged circumferentially around the circumference of the dehumidification mechanism 5 at the axis, and a filter material 521 for removing water is arranged in the dehumidification mechanism 5; it can be seen that a channel for air flow is formed between the air inlet cabin 3, the plurality of dehumidification mechanisms 5 and the air outlet cabin 4.

[0023] The air inlet compartment 3 is rotatably sleeved with an air inlet end rotating cap 32 on one side facing the dehumidification mechanism 5, and the air outlet compartment 4 is rotatably sleeved with an air outlet end rotating cap 42 on one side facing the dehumidification mechanism 5. One end of the dehumidification mechanism 5 is elastically plugged into the air inlet end rotating cap 32, and the other end of the dehumidification mechanism 5 is plugged into the air outlet end rotating cap 42. It can be seen that the dehumidification mechanism 5 and the air inlet end rotating caps 32 and the air outlet end rotating caps 42 on both sides form a rotating whole, that is, the three can rotate synchronously, wherein the elastic plug-in can position the dehumidification mechanism 5 between the air inlet end rotating cap 32 and the air outlet end rotating cap 42, and also facilitates the disassembly of the dehumidification mechanism 5 between the air inlet end rotating cap 32 and the air outlet end rotating cap 42.

[0024] like Figure 3 As shown, a plurality of sealing components 33 are provided in the air inlet compartment 3, and the plurality of sealing components 33 correspond one to one with the plurality of dehumidification mechanisms 5. The dehumidification mechanisms 5 at corresponding positions are turned on and off by turning on and off the sealing components 33. It should be noted here that the sealing components 33 can block or unblock the airflow channel formed by themselves through changes in the internal structure.

[0025] like Figure 2 As shown, a driving assembly 6 is provided on one side of the air inlet compartment 3 and the air outlet compartment 4, and the driving assembly 6 includes a double-headed motor 61 and two driving wheels 62. The two driving wheels 62 are connected to the output end of the double-headed motor 61 through a shaft key, and the two driving wheels 62 are respectively abutted against the air inlet end rotating cap 32 and the air outlet end rotating cap 42. It should be noted that as long as a transmission relationship can be formed between the driving wheel 62, the air inlet end rotating cap 32 and the air outlet end rotating cap 42, for example, the driving wheel 62 is a gear, then the outer sides of the air inlet end rotating cap 32 and the air outlet end rotating cap 42 are designed to be gear rings meshing with the driving wheel 62, and no specific limitation is made here.

[0026] In addition, the high-efficiency drying device for producing forsterite castables according to the embodiment of the present application also has the following additional technical features: like Figure 3 and Figure 5 As shown, the air intake chamber 3 includes an air intake hood 31 mounted on the kiln 1, and the air intake hood 31 is provided with an air inlet 311 connected with the first high-pressure blower 2, and the air intake end rotating cap 32 is rotatably mounted on the air intake hood 31, and the air intake hood 31 has a plurality of air intake holes 312 evenly arranged on one end of the air intake hood 31 facing the air intake end rotating cap 32. It should be noted here that, among the plurality of dehumidification mechanisms 5, only the end of the dehumidification mechanism 5 that is performing dehumidification work is inserted into the corresponding air intake hole 312, and the ends of the other dehumidification mechanisms 5 located on this side are not in contact with the air intake hole 312.

[0027] Furthermore, a plurality of limit through holes 321 are evenly arranged on the air inlet end rotating cap 32, and the plurality of limit through holes 321 correspond one-to-one to the plurality of air inlet through holes 312, and the plurality of limit through holes 321 correspond one-to-one to the plurality of dehumidification mechanisms 5. It should be noted here that all the dehumidification mechanisms 5 are inserted into their respective corresponding limit through holes 321 to form an axially rotating whole with the air inlet end rotating cap 32.

[0028] like Figure 3-Figure 6 As shown, the blocking assembly 33 includes a blocking cover 331, a plug 332, a limiting rod 333, a first spring 334 and a second spring 335. The blocking cover 331 is fixedly connected to the air inlet cover 31 and covers the air inlet 311; the plug 332 is elastically slidably inserted into the blocking cover 331; the limiting rod 333 is fixedly connected to the plug 332 and slidably extends out of the blocking cover 331; the first spring 334 is sleeved on the limiting rod 333, and the two ends of the first spring 334 are respectively abutted against the blocking cover 331 and the plug 332; the second spring 335 is sleeved on the dehumidification mechanism 5, one end of the second spring 335 is abutted against the air inlet end rotating cap 32, and the other end of the second spring 335 is abutted against the dehumidification mechanism 5. It should be noted that the end of the dehumidification mechanism 5 on this side can abut against the plug 332 by compressing the second spring 335, and push the plug 332 to compress the first spring 334.

[0029] It should be noted that the first spring 334 helps the plug 332 to reset inside the sealing cover 331, that is, the plug 332 seals the inside of the sealing cover 331, and the second spring 335 helps to reset and position the dehumidification mechanism 5 to avoid the dehumidification mechanism 5 from falling off during actual use.

[0030] Furthermore, a plurality of first notches 336 are evenly arranged in the circumferential direction at one end of the side wall of the blocking cover 331 facing the air inlet 311 .

[0031] Among them, the side wall of the plug 332 faces one end of the limiting rod 333, and a plurality of second notches 337 are evenly arranged in the circumferential direction; the side wall of the plug 332 and the inner wall of the sealing cover 331 are sealed and slidably matched; the second notches 337 and the first notches 336 correspond one to one.

[0032] It can be understood that when the dehumidification mechanism 5 compresses the second spring 335 and inserts it into the air inlet hole 312, and pushes the plug 332 to compress the first spring 334, the plug 332 undergoes axial displacement inside the sealing cover 331, and the second notch 337 and the first notch 336 on the plug 332 are connected. At this time, the hot air flow in the air inlet cover 31 can enter the corresponding dehumidification mechanism 5 from here to perform dehumidification operation.

[0033] like Figure 3 and Figure 4As shown, an end of the air intake hood 31 away from the air intake end rotating cap 32 is also fixedly connected to an axial telescopic member 34, the fixed end of the axial telescopic member 34 is fixedly connected to the air intake hood 31, and a piston rod 341 of the axial telescopic member 34 is inserted into the air intake hood 31 and fixedly connected to a limiting rod 333 located at the axis of the air intake hood 31.

[0034] It can be understood here that the air flow channel in the sealing assembly 33 located at the axis of the air inlet cover 31 is controlled by the axial telescopic member 34. It can be understood that when the piston rod 341 of the axial telescopic member 34 is retracted, the limiting rod 333 in the sealing assembly 33 will drive the plug 332 to move inside the sealing cover 331 toward the axial telescopic member 34, so that the air flow channel is opened. Conversely, when the piston rod 341 of the axial telescopic member 34 is extended, the limiting rod 333 in the sealing assembly 33 will drive the plug 332 to move axially in the opposite direction inside the sealing cover 331, which will close the air flow channel in the sealing assembly 33.

[0035] like Figure 7 As shown, the air outlet chamber 4 includes an air outlet hood 41 mounted on the kiln 1, and the air outlet hood 41 is provided with an air outlet port 411 connected to the second high-pressure blower 21, and an air outlet end rotating cap 42 is rotatably mounted on the air outlet hood 41, and the air outlet hood 41 is evenly provided with air outlet holes 412 corresponding to multiple dehumidification mechanisms 5 at one end of the air outlet hood 41 facing the air outlet end rotating cap 42.

[0036] It should be noted here that the multiple dehumidification mechanisms 5 are located at one end of this side, and are all plugged into the air outlet rotating cap 42, and are not plugged into the air outlet through hole 412, so as to avoid rotation interference between the multiple dehumidification mechanisms 5.

[0037] An eccentric telescopic member 43 is fixedly connected to one end of the air outlet hood 41 away from the air outlet rotating cap 42, and an abutment member 431 is fixedly connected to the piston end of the eccentric telescopic member 43. The abutment member 431 penetrates the air outlet hood 41 and abuts against the dehumidification mechanism 5 at a non-axial position.

[0038] It should be noted here that, through the displacement of the piston end of the eccentric telescopic member 43, the abutment member 431 will be driven to cause the dehumidification mechanism 5 at the corresponding non-axial position to undergo axial displacement, so that the end of the dehumidification mechanism 5 close to the air inlet hood 31 mentioned above will abut against the corresponding plug 332.

[0039] The following describes the use process of a high-efficiency drying device for producing forsterite castables according to an embodiment of the present application with reference to the accompanying drawings: When in use, the formed forsterite castable is slowly displaced in the kiln 1 along the direction of the track 11, and the forsterite castable in the kiln 1 is dried by the lower air heating component 12 and the upper air heating component 13. At the same time, due to the evaporation of water during the drying process, hot air containing water will be formed inside the kiln 1. The first high-pressure blower 2 on the side of the feed end 14 is used to adsorb the hot air flow containing water and transport it to the air inlet hood 31. The expansion and contraction change of the eccentric expansion member 43 in the direction of the air outlet hood 41 is used to push the corresponding dehumidification mechanism 5 to undergo axial displacement, that is, compress the second spring 335 thereon, and The first spring 334 is pressed against the corresponding plug 332, so that the plug 332 is axially displaced in the corresponding blocking cover 331, and the first spring 334 is squeezed. The displacement of the plug 332 will make the first notch 336 and the second notch 337 that originally formed the blockage connected. At this time, the hot air flow will flow through the dehumidification mechanism 5 that forms a passage there, and absorb moisture with the help of the filter material 521 in the dehumidification mechanism 5. Then, the air flow enters the air outlet cover 41 from the other end of the dehumidification mechanism 5, and is extracted by the second high-pressure blower 21 and transported to the inside of the kiln 1 from the side of the discharge end 15, so as to realize the recovery and reuse of heat energy and play a role in energy conservation. There will be a certain degree of saving effect. In the above dehumidification process, in this application, the double-headed motor 61 is used to drive the driving wheels 62 on both sides to drive the air inlet end rotating cap 32, the dehumidification mechanism 5 and the air outlet end rotating cap 42 to rotate. Specifically, the rotation angles of the air inlet end rotating cap 32, the dehumidification mechanism 5 and the air outlet end rotating cap 42 are determined according to the number of dehumidification mechanisms 5 actually designed on the outside and the number of dehumidification mechanisms 5 actually used. In this application, there are six peripheral dehumidification mechanisms 5, and the actual use of one dehumidification mechanism 5 is used as an example for explanation. When the filter material 521 inside the dehumidification mechanism 5 in use After saturation, the axial telescopic member 34 controls the blocking component 33 at the axial center to open the airflow channel, and at the same time the eccentric telescopic member 43 releases the push on the saturated dehumidification mechanism 5, that is, the abutment member 431 is recovered to be separated from the saturated dehumidification mechanism 5, and then the double-headed motor 61 drives the multiple dehumidification mechanisms 5 to rotate 60 degrees. At this time, the axial telescopic member 34 and the eccentric telescopic member 43 operate in reverse, which will cause the dehumidification mechanism 5 at the axial center to suspend the airflow, and the airflow passes through the newly turned dehumidification mechanism 5. This design can realize the replacement of the saturated dehumidification mechanism 5 without stopping the machine, improve the treatment efficiency of moisture in the hot air, and further improve the recovery and reuse efficiency of heat energy; It should be noted that, since only one of the multiple dehumidification mechanisms 5 is kept unobstructed, the suction force provided by the second high-pressure blower 21 can only draw out the dried airflow from the dehumidification mechanism 5 .

[0040] Embodiment 2. In the related art, the dehumidification mechanism 5 is usually directly filled with a filter material 521 with water absorption capacity, and then air flow is introduced from one end and air flow is discharged from the other end. However, since the filter material 521 will be saturated after absorbing water, once the direct filling method is adopted, the saturated filter material 521 will cause blockage inside the dehumidification mechanism 5, affecting the air flow. At the same time, the saturation speed of the end that is in contact with more air flow is significantly greater than that of the other end, which will affect the utilization rate of the filter material 521 and increase the frequent replacement of the dehumidification mechanism 5.

[0041] According to some embodiments of the present application, Figure 8-Figure 11 As shown, the dehumidification mechanism 5 includes a shell 51, a dehumidification component 52 and an outer flow guide member 53. The two ends of the shell 51 are respectively plugged into the air inlet end rotating cap 32 and the air outlet end rotating cap 42; the dehumidification component 52 is coaxially plugged into the shell 51 for adsorbing moisture; the outer flow guide member 53 is arranged along the axial spiral of the dehumidification component 52, and the outer flow guide member 53 is slidably plugged into the shell 51, and the outer flow guide member 53 is slidably sleeved on the dehumidification component 52.

[0042] Furthermore, the housing 51 includes a straight-cylindrical outer shell 512 , and an air inlet cover 511 and an air outlet cover 513 respectively sleeved on both ends of the outer shell 512 . It should be noted that the second spring 335 is sleeved on the air inlet cover 511 .

[0043] Among them, the dehumidification component 52 includes a filter material 521, an inner net tube 522, an outer net tube 523, a guide cover 524, a sealing plate 525 and a support ring 526. The filter material 521 is sleeved on the inner net tube 522; the outer net tube 523 is sleeved on the filter material 521; the guide cover 524 is fixedly connected to the inner net tube 522 and the outer net tube 523 at one end facing the air inlet end cover 511. It should be noted that there is a spacing between the surrounding side of the guide cover 524 and the outer shell 512; the sealing plate 525 is fixedly connected to the inner net tube 522 and the outer net tube 523 at one end facing the air outlet end cover 513, and the sealing plate 525 is sealed and plugged into the shell 51; the support ring 526 is fixedly sleeved on the end of the inner net tube 522 extending from the filter material 521, and the support ring 526 is sealed and plugged into the air outlet end cover 513.

[0044] It should be noted that in the specific embodiment of the present application, the filter material 521 is a water-absorbing material, such as activated alumina, silica gel, a limiting material, activated carbon, etc., which is selected according to actual conditions and will not be elaborated here.

[0045] It should be further explained that the design of the support ring 526 can facilitate the eccentric telescopic member 43 to drive the abutment member 431 to be inserted into the air outlet end cover 513 and abut against the support ring 526, thereby improving the strength of the dehumidification component 52.

[0046] Furthermore, one end of the guide cover 524 facing the air outlet cover 513 is conical, which has the effect of radiating the incoming airflow.

[0047] Furthermore, the pitch of the outer guide member 53 gradually decreases from the direction of the gas outlet end cover 513 to the direction of the gas outlet end cover 513 .

[0048] Therefore, when the airflow enters the shell body 51 from the air inlet end cover 511, the airflow will first be guided by the end face of the guide cover 524 to form a radiation state that diffuses toward the circumferential side, and then rush to the gap formed between the outer shell 512 and the outer mesh tube 523. During this process, the airflow is again guided by the spirally designed outer guide member 53, so that the airflow flows along a spiral path between the outer shell 512 and the outer mesh tube 523, and one end of the air outlet end cover 513 is blocked by the sealing plate 525, which blocks the airflow from continuing to flow axially. Therefore, the airflow will flow from the side wall of the outer mesh tube 523 to the internal filter material 521, and finally pass through the inner mesh tube 522, converge at the axis, flow axially toward the air outlet end cover 513, and then flow into the air outlet from the air outlet end cover 513. In the cover 41, during this process, the airflow is guided by the guide cover 524 to avoid directly entering from the end face of the columnar filter material 521, thereby avoiding the filter material 521 from accelerating to saturate toward the end of the air inlet cover 511. The spirally designed outer guide member 53 continues to guide the airflow from the side wall direction, so that part of the airflow can radially enter the filter material 521 at the end close to the air inlet cover 511, and part of the airflow continues to flow toward the air outlet cover 513. In the process of flowing, the airflow is gradually forced to radially enter the corresponding filter material 521 due to the reduction of the channel. In this way, the filter material 521 in the entire shell 51 can be fully utilized, and the adsorption capacity of moisture in the hot air flow is also enhanced, thereby improving the dehumidification effect of the dehumidification mechanism 5 on moisture in the hot air flow.

[0049] Embodiment 3, in the related technology, the guidance of the air flow path inside the dehumidification component 52 enhances the utilization rate of the filter material 521. However, because the overall flow direction of the airflow in the outer shell 512 is axial, although the outer guide member 53 provides a certain radial guidance to the airflow, the airflow entering the filter material 521 will produce turbulence in the axial direction or even in the radial direction due to different flow rates. That is, the airflow entering the filter material 521 may continue to return to the space between the outer shell 512 and the outer mesh tube 523. In this way, the actual dehumidification effect of the filter material 521 inside the entire outer mesh tube 523 on the airflow is reduced. At the same time, the axial positioning support for the dehumidification component 52 in the shell 51 is formed by only the sealing plate 525 and the support ring 526, which may easily cause the dehumidification component 52 to be axially offset in the shell 51, thereby further affecting its actual dehumidification capacity.

[0050] According to some embodiments of the present application, Figure 12-14As shown, an inner flow guide 54 is coaxially arranged between the inner mesh tube 522 and the outer mesh tube 523 . The inner flow guide 54 is arranged in a spiral shape, and the pitch of the inner flow guide 54 gradually decreases from the direction of the air outlet end cover 513 to the direction of the air outlet end cover 513 .

[0051] It can be seen from this that the original columnar filter material 521 is divided into a spiral shape by the inner flow guide 54 .

[0052] Furthermore, an end support member 55 is coaxially sleeved on the outer side of the deflector cover 524, and the end support member 55 includes an outer ring 551 and a plurality of spokes 552 uniformly fixed in the outer ring 551. The outer ring 551 is slidably inserted in the shell 51, and the plurality of spokes 552 are fixed to the deflector cover 524, and the spokes 552 are deflected in the axial direction of the outer ring 551.

[0053] It should be noted that the multiple spokes 552 not only play a supporting role, but also have a homogenizing effect on the airflow entering the outer shell 512 and the outer mesh tube 523 to a certain extent due to their own deflection settings.

[0054] It should be noted that the pitch, pitch variation, and spiral direction of the inner flow guide 54 and the outer flow guide 53 are designed to be the same.

[0055] Therefore, after the airflow is evenly divided by the multiple spokes 552 and enters the outer shell 512 and the outer net tube 523, the airflow is firstly guided from the side wall direction by the spirally designed outer guide 53, so that part of the airflow can radially enter the filter material 521 at the end close to the air inlet end cover 511, and part of the airflow continues to flow toward the air outlet end cover 513. In the process of flowing, the airflow is gradually forced to radially enter the corresponding filter material 521 due to the narrowing of the channel. The airflow entering the filter material 521 is further reduced due to the gradually narrowing pitch of the inner guide 553. 4, the airflow that may have generated turbulence in the filter material 521 will be further guided to change, so that the flow direction of the airflow tends to be stable, and a part of the airflow in the filter material 521 is forced to form a certain degree of axial displacement, that is, the contact between the airflow and the filter material 521 is increased, and the adsorption of moisture in the airflow by the filter material 521 is further improved. In this way, the utilization rate of the filter material 521 is further improved, and the dehumidification efficiency of the dehumidification mechanism 5 is enhanced at the same time, so as to avoid the hot air flow transported back to the kiln 1 containing more moisture, which affects the actual drying effect and efficiency of the forsterite castable.

[0056] On the other hand, the embodiment of the present application further provides an energy-saving method for a high-efficiency drying device for producing forsterite castables, comprising the following steps: S1: Drying the forsterite castable, transporting the formed forsterite castable into the kiln 1, and drying the formed forsterite castable by utilizing the heat inside the kiln 1; S2: air circulation. During the drying process, the first high-pressure blower 2 is used to absorb the hot air flow with moisture generated in the kiln 1 and discharge it to the air inlet chamber 3. The moisture in the hot air flow is adsorbed by one or more dehumidification mechanisms 5. Then, the second high-pressure blower 21 is used to extract the dehumidified hot air flow from the air outlet chamber 4 and discharge it to the kiln 1, thereby improving the utilization rate of thermal energy. S3: Replace the saturated dehumidification mechanism 5. During the dehumidification process, the double-headed motor 61 drives the multiple dehumidification mechanisms 5 that form a whole to rotate, and the sealing component 33 is used to control the dehumidification mechanism 5 at the axis to form a passage, and the dehumidification mechanism 5 on the outside forms a closed path. Then the saturated dehumidification mechanism 5 is removed and replaced with a new one, and the sealing component 33 is used again to open the dehumidification mechanism 5 at the axis, and one or several on the outside form a passage, and the dehumidification mechanism 5 on the outside continues to be used to adsorb moisture in the hot air flow.

[0057] It should be noted that the specific models and specifications of the kiln 1, track 11, lower air heating assembly 12, upper air heating assembly 13, first high-pressure blower 2, second high-pressure blower 21, first spring 334, second spring 335, axial telescopic member 34, eccentric telescopic member 43 and double-headed motor 61 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it will not be described in detail.

For those skilled in the art, the present application may have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
