A drying device for refractory production

Abstract

The invention discloses a drying device for refractory material production, and relates to the technical field of refractory material drying. The drying device for refractory material production comprises a drying component. Since a material-push wheel and a push tooth are both hollow, when steam enters the material-push wheel, all the push teeth are filled, so that all the push teeth can dry the refractory material. Since through holes are provided on the push teeth for facilitating the flow of the refractory material, when the material-push wheel rotates, a certain push tooth pushes the refractory material, but due to the existence of the through hole, the refractory material flows to the next push tooth, and so on, the refractory material flows out of the through hole, and then falls on the next push tooth uninterruptedly, so as to form a state that can flow back and be pushed, thereby increasing the fluidity of the refractory material, and fully increasing the contact area between the refractory material and the push tooth and the material-push wheel, so as to achieve a rapid drying effect, and greatly improve the drying efficiency of the refractory material.

Description

Technical Field

[0001] The present invention specifically relates to the technical field of refractory drying, and more specifically, to a drying device for refractory production. Background Art

[0002] Refractory materials are applied to various fields of the national economy such as iron and steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, and military industry. They are essential basic materials to ensure the production operation and technological development of the above industries and play an irreplaceable important role in the development of high-temperature industrial production.

[0003] Chinese Patent Publication No. CN 217929598 U discloses a drying device for refractory production, including a cylinder body and a support. The cylinder body is fixedly installed on the upper part of the support. The centers of both ends of the cylinder body are rotationally connected with rotating shafts. A fixed rod is fixedly connected to the outer ring surface of the middle part of the rotating shaft. Bases are fixedly connected to both inner conical surfaces of the cylinder body. Rotating discs are rotationally connected to both bases. A scraper is fixedly connected between the two rotating discs. The two ends of the scraper are fixedly connected to the inner side surfaces of the two rotating discs respectively.

[0004] Although the drying device in the above patent can dry refractory materials, due to incomplete pulverization during the original processing of refractory materials, the mixing of powder materials and granular materials occurs, resulting in the mixing of incompletely pulverized granular materials and powder materials. And the traditional screening device needs to screen after the refractory materials are dried, and the combined use of multiple devices leads to a reduction in the drying and screening efficiency of refractory materials. Moreover, the existing drying device uses a stirring paddle to stir the materials to increase the drying efficiency. However, when drying refractory materials, it is a large-area stirring, and the refractory materials at the bottom of the tank cannot be fully stirred, resulting in uneven drying of the materials, a long drying efficiency time, and the inability to achieve non-stop material drying.

[0014] As a further technical solution of the present invention, a plurality of fixed connection seats are annularly and evenly distributed on one side of the material distributing wheel where the transmission shaft cylinder is welded; the fixed connection seats are movably connected to a tensioner through a rotating shaft, and the other end of the tensioner is fixed on the transmission shaft cylinder through a fixed connection seat.

[0015] As a further technical solution of the present invention, the transmission assembly includes a transmission shaft cylinder, and both ends of the transmission shaft cylinder are fixed on the U-shaped seat through bearings; a transmission wheel is fitted and installed at one end of the transmission shaft cylinder away from the material pushing wheel; there are two transmission wheels, and the other transmission wheel is fitted and installed on the output shaft of the speed reducer, and the two transmission wheels are connected by a transmission belt; the input end of the speed reducer is connected to the motor in a matching manner, and the speed reducer is fixedly connected to the U-shaped seat;

[0016] One end of the transmission shaft cylinder where the transmission wheel is provided is connected to the steam inlet pipe through a rotary joint; the steam inlet pipe is connected to the steam engine.

[0017] As a further technical solution of the present invention, a powder extraction pipe is connected to the outside of the material suction shell, and the powder extraction pipe is fixedly connected to the outer fixing plate through a fixing frame, and the end of the powder extraction pipe is connected to a negative pressure tank; the end of the material extraction pipe is connected to a negative pressure aggregate tank.

[0018] As a further technical solution of the present invention, the drying assembly is fixed inside the outer frame, and a base is fixed on one side of the outer frame, and a bracket for facilitating the fixation of the transmission assembly is connected to the base through bolts.

[0019] As a further technical solution of the present invention, a storage hopper is arranged on one side of the outer frame, and a screw conveyor is fixed in the storage hopper, and the output end of the screw conveyor is located above the feed hopper.

[0020] As a further technical solution of the present invention, a discharge port is opened on one side of the annular shell, and the discharge port is within the material receiving range of the aggregating member.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. In the present invention, when in use, first pour the refractory material to be dried into the storage hopper, the screw conveyor conveys the refractory material to the feed hopper, and then the refractory material enters the drying assembly. At this time, the transmission assembly drives the drying assembly to rotate. At the same time, the steam from the steam inlet pipe enters the drying assembly to dry the refractory material;

[0023] 2. In the present invention, since the paddle wheel and the paddle teeth are both hollow, when steam enters the paddle wheel, all the paddle teeth will be filled, so that all the paddle teeth can dry the refractory material; and all the paddle teeth are provided with through holes for facilitating the flow of the refractory material, so when the paddle wheel rotates, a certain paddle tooth paddles the refractory material, but due to the existence of the through hole, the refractory material will flow to the next paddle tooth, and so on, the refractory material flows out of the through hole and then falls on the next paddle tooth uninterruptedly, thereby forming a state that can flow back and be moved, thereby increasing the fluidity of the refractory material, and fully increasing the contact area between the refractory material and the paddle teeth and the paddle wheel, thereby achieving a rapid drying effect, and greatly improving the drying efficiency of the refractory material;

[0024] 3. In the present invention, since the refractory material is in powder form, due to the influence of other factors during the preparation of the refractory material, a part of the granular refractory material may be mixed in the powder refractory material, and during drying, the powder refractory material may be dried earlier than the granular refractory material. Therefore, a discharge hole is provided on one side of the paddle wheel close to the outer fixed plate. After the powder refractory material is dried, it will be discharged through the discharge hole. At this time, negative pressure will be introduced into the powder extraction pipe, and the powder refractory material will be sucked into the negative pressure tank for storage under the suction force of the negative pressure.

[0025] 4. In the present invention, after the powder refractory material has been extracted (judged by the flow meter arranged on the extraction pipe), the cylinder rod of the electric push cylinder is extended to slide the driving plate along the inner side of the fixed axis by using the pushing claw, so that the material blocking plate passes through the material-pickup wheel and fits with the picking teeth. At this time, the picking teeth have better plucking performance when plucking the granular refractory material, and can drive a large amount of refractory material to rotate. When it rotates to the discharge port, the material blocking plate and the picking teeth are both in an inclined state, and the centrifugal force when the material-pickup wheel rotates can make the granular refractory material be discharged from the discharge port and fall into the collection piece. At this time, the negative pressure of the powder extraction pipe is closed, and the negative pressure on the extraction pipe is opened, so that the granular refractory material is pumped into the negative pressure collection tank; thereby, the separation and separate storage of the powder refractory material and the granular refractory material are realized;

[0026] 5. In the present invention, after the granular refractory material is extracted, the cylinder rod of the electric push cylinder is retracted, the driving plate returns to its original position along the fixed axis under the push of the spring, the material blocking plate is separated from the material-dispensing wheel, and then the refractory material to be dried continues to be added into the drying assembly, thereby realizing non-stop operation of the equipment, greatly saving waiting time and improving work efficiency;

[0027] 6. In the present invention, when the transmission component drives the drying component, the motor drives the reducer to rotate. The reducer drives the transmission shaft cylinder to rotate under the cooperation of the transmission wheel and the transmission belt. Since the transmission shaft cylinder is connected to the steam inlet pipe through a rotary joint, the steam can enter while ensuring that the transmission shaft cylinder drives the material distributing wheel to rotate normally, so as to realize the drying of refractory materials by steam in the equipment. Moreover, two pressure relief valves are arranged on the side of the material distributing wheel where the transmission shaft cylinder is provided to ensure the normal circulation and pressure relief of the steam in the material distributing wheel. The openings of the pressure relief valves face outward, and the discharged steam has no impact on the refractory materials.

[0028] 7. In the present invention, when the material distributing wheel rotates, due to the accumulation of refractory materials, the force on the material distributing wheel is uneven during rotation, resulting in eccentricity. Therefore, a plurality of fixed connection seats are evenly distributed in a ring shape on the side of the material distributing wheel where the transmission shaft cylinder is welded. The fixed connection seats are movably connected to the tensioner through a rotating shaft, and the other end of the tensioner is fixed to the transmission shaft cylinder through a fixed connection seat. The use of a plurality of tensioners ensures that the transmission shaft cylinder and the material distributing wheel are in a relatively stable rotating state, avoiding the occurrence of eccentricity.

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Please refer to Figure 1-13 , in the embodiment of the present invention, a drying device for refractory material production includes a drying component 9. The drying component 9 is fixed inside the outer frame 1, and a base 7 is fixed on one side of the outer frame 1. A bracket 8 for facilitating the fixing of the transmission component 2 is connected to the base 7 by bolts.

[0048] Specifically, a storage hopper 6 is provided on one side of the outer frame 1, and an auger conveyor 5 is fixed in the storage hopper 6. The output end of the auger conveyor 5 is located above the feed hopper 4, and a drying component 9 is fixed on the top of the drying component 9. The transmission component 2 is installed behind the drying component 9.

[0049] As a further explanation of this embodiment, the drying assembly 9 includes two side upright plates 91 arranged parallel to each other and fixed on both sides of the inner fixing plate 92 and the outer fixing plate 94; a dryer 96 is arranged between the inner fixing plate 92 and the outer fixing plate 94;

[0050] The dryer 96 includes an annular outer shell 961, which is rotatably connected to a material-discharging wheel 962 inside, and a fixed shaft 966 is welded on one side of the material-discharging wheel 962, and a driving plate 965 is mounted on the fixed shaft 966, and a spring 967 sleeved on the fixed shaft 966 is arranged on the inner side of the driving plate 965; a plurality of material-blocking plates 964 are welded to the outer periphery of the driving plate 965, and a pushing claw 95 is fittedly connected to the outer side of the driving plate 965, and the pushing claw 95 is fixed on the cylinder rod of the electric push cylinder 99; the electric push cylinder 99 is fixed on a cross fixing frame 98, and the cross fixing frame 98 is fixed to the inner side of the suction shell 910 by bolts; the suction shell 910 is fixedly connected to the outer fixing plate 94 by bolts.

[0051] By adopting the above technical solution, when in use, the refractory material to be dried is first poured into the storage hopper 6, and the auger conveyor 5 conveys the refractory material to the feed hopper 4, and then the refractory material enters the drying component 9, at which time the transmission component 2 drives the drying component 9 to rotate, and at the same time, the steam from the steam inlet pipe 10 enters the drying component 9 to dry the refractory material;

[0052] Since the paddle wheel 962 and the paddle teeth are hollow, when steam enters the paddle wheel 962, all the paddle teeth will be filled, so that all the paddle teeth can dry the refractory material; and all the paddle teeth are provided with through holes for facilitating the flow of the refractory material. Therefore, when the paddle wheel 962 rotates, a certain paddle tooth will paddle the refractory material, but due to the existence of the through hole, the refractory material will flow to the next paddle tooth, and so on. The refractory material flows out of the through hole and then falls on the next paddle tooth continuously, thus forming a state that can flow back and be moved, thereby increasing the fluidity of the refractory material and fully increasing the contact area between the refractory material and the paddle teeth and the paddle wheel 962, thereby achieving the effect of rapid drying and greatly improving the drying efficiency of the refractory material.

[0053] In this embodiment, a top plate 93 is fixed on the top of the inner fixing plate 92 and the outer fixing plate 94 to facilitate the installation of the feed hopper 4; a material collecting piece 97 is arranged under the dryer 96; a material extraction pipe 12 is embedded on the outer fixing plate 94, and the material extraction pipe 12 is connected to the inner cavity of the material collecting piece 97.

[0054] Furthermore, a plurality of material-moving teeth are welded to the outside of the material-moving wheel 962, and a plurality of material-flowing holes are opened on each material-moving tooth. The material-moving wheel 962 and the material-moving teeth are both hollow, and a transmission shaft cylinder 22 is welded to one side of the material-moving wheel 962 close to the inner fixed plate 92;

[0055] The plurality of material-selecting teeth are arranged in groups of two, and a material-blocking plate 964 is provided on one side of each group of material-selecting teeth; a discharge hole 963 is provided on the side of the material-selecting wheel 962 close to the outer fixed plate 94, and a rectangular groove is provided on the side for the material-blocking plate 964 to slide and connect. A powder extraction pipe 3 is connected to the outer side of the suction shell 910, and the powder extraction pipe 3 is fixedly connected to the outer fixed plate 94 through a fixing frame 11, and the end of the powder extraction pipe 3 is connected to a negative pressure tank; the end of the extraction pipe 12 is connected to a negative pressure material collection tank; a discharge port 968 is provided on one side of the annular shell 961, and the discharge port 968 is located within the material receiving range of the material collection member 97.

[0056] By adopting the above technical solution, since the refractory material is in powder form, due to the influence of other factors during the preparation of the refractory material, a part of the granular refractory material will be mixed in the powder refractory material, and during drying, the powder refractory material will be dried earlier than the granular refractory material. Therefore, a discharge hole 963 is opened on the side of the paddle wheel 962 close to the outer fixed plate 94. After the powder refractory material is dried, it will be discharged through the discharge hole 963. At this time, negative pressure will be introduced into the powder extraction pipe 3, and it will be sucked into the negative pressure tank for storage under the suction force of the negative pressure.

[0057] After the powder refractory material has been extracted (determined by the flow meter set on the extraction pipe 12), the cylinder rod of the electric push cylinder 99 is extended to use the pushing claw 95 to slide the driving plate 965 inward along the fixed axis 966, so that the material blocking plate 964 passes through the material-push wheel 962 and fits with the paddle teeth. At this time, the paddle teeth have better paddle properties when paddle the granular refractory material, and can drive a large amount of refractory material to rotate. When it rotates to the discharge port 968, the material blocking plate 964 and the paddle teeth are in an inclined state, and the centrifugal force when the paddle wheel 962 rotates can make the granular refractory material be discharged from the discharge port 968 and fall into the collecting piece 97. At this time, the negative pressure of the powder extraction pipe 3 is closed, and the negative pressure on the extraction pipe 12 is opened, so that the granular refractory material is extracted into the negative pressure collecting tank; thereby realizing the separation and separate storage of the powder refractory material and the granular refractory material.

[0058] As a further illustration, after the granular refractory material is extracted, the cylinder rod of the electric push cylinder 99 retracts. The driving plate 965 returns to its original position along the fixed shaft 966 under the pushing of the spring 967. The material blocking plate 964 separates from the material feeding wheel 962. Subsequently, the refractory material to be dried is continuously added into the drying assembly 9, thus realizing the non-stop operation of the equipment, greatly saving the waiting time and improving the working efficiency.

[0059] In this embodiment, the rotating diameter of the material feeding teeth is larger than the outer diameter of the material feeding wheel 962, and the material feeding teeth are in contact with the annular housing 961. The annular housing 961 is arranged in a convex shape. The two sides and the inner side of the annular housing 961 are fitted with the inner fixing plate 92 and the outer fixing plate 94 and fixed by bolts.

[0060] By adopting the above technical solution, the rotating diameter of the material feeding teeth is larger than the outer diameter of the material feeding wheel 962, and the material feeding teeth are in contact with the annular housing 961, which can stir the refractory material in a large range, prevent the occurrence of dead materials at the bottom, and improve the fluidity of the refractory material.

[0061] In this embodiment, a plurality of fixed connection seats 969 are evenly distributed in a ring on one side of the material feeding wheel 962 where the transmission shaft cylinder 22 is welded. The fixed connection seats 969 are movably connected to the tensioner 970 through a rotating shaft, and the other end of the tensioner 970 is fixed on the transmission shaft cylinder 22 through the fixed connection seat 969.

[0062] By adopting the above technical solution, when the material feeding wheel 962 rotates, due to the aggregation of the refractory material, the force on the material feeding wheel 962 is uneven during rotation, resulting in eccentricity. Therefore, a plurality of fixed connection seats 969 are evenly distributed in a ring on one side of the material feeding wheel 962 where the transmission shaft cylinder 22 is welded. The fixed connection seats 969 are movably connected to the tensioner 970 through a rotating shaft, and the other end of the tensioner 970 is fixed on the transmission shaft cylinder 22 through the fixed connection seat 969. The use of multiple tensioners 970 ensures that the transmission shaft cylinder 22 and the material feeding wheel 962 are in a relatively stable rotating state and avoids the occurrence of eccentricity.

[0063] In this embodiment, the transmission assembly 2 includes a transmission shaft cylinder 22, and both ends of the transmission shaft cylinder 22 are fixed on the U-shaped seat 21 through bearings. A transmission wheel 24 is fitted at one end of the transmission shaft cylinder 22 away from the material feeding wheel 962. There are two transmission wheels 24, and the other transmission wheel 24 is fitted on the output shaft of the speed reducer 26. The two transmission wheels 24 are connected by a transmission belt 25. The input end of the speed reducer 26 is connected to the motor 27, and the speed reducer 26 is fixed to the U-shaped seat 21.

[0064] One end of the transmission shaft cylinder 22, where a transmission wheel 24 is provided, is connected to the steam inlet pipe 10 through a rotary joint 23; the steam inlet pipe 10 is connected to a steam engine.

[0065] By adopting the above technical solution, when the transmission assembly 2 drives the drying assembly 9, the motor 27 drives the speed reducer 26 to rotate. The speed reducer 26 drives the transmission shaft cylinder 22 to rotate under the cooperation of the transmission wheel 24 and the transmission belt 25. Since the transmission shaft cylinder 22 is connected to the steam inlet pipe 10 through the rotary joint 23, the entry of steam is realized while ensuring the normal rotation of the material distributing wheel 962 driven by the transmission shaft cylinder 22, so as to realize the drying of refractory materials by the equipment with steam; moreover, two pressure relief valves are arranged on one side of the material distributing wheel 962 where the transmission shaft cylinder 22 is provided, ensuring the normal circulation and pressure relief of the steam in the material distributing wheel 962, and the openings of the pressure relief valves face outward, and the discharged steam has no influence on the refractory materials.

[0066] The working principle of the present invention is as follows: during use, first pour the refractory materials to be dried into the storage hopper 6, and the screw conveyor 5 conveys the refractory materials to the feed hopper 4. Subsequently, the refractory materials enter the drying assembly 9. At this time, the transmission assembly 2 drives the drying assembly 9 to rotate. At the same time, the steam from the steam inlet pipe 10 enters the drying assembly 9 to dry the refractory materials; when the transmission assembly 2 drives the drying assembly 9, the motor 27 drives the speed reducer 26 to rotate. The speed reducer 26 drives the transmission shaft cylinder 22 to rotate under the cooperation of the transmission wheel 24 and the transmission belt 25. Since the transmission shaft cylinder 22 is connected to the steam inlet pipe 10 through the rotary joint 23, the entry of steam is realized while ensuring the normal rotation of the material distributing wheel 962 driven by the transmission shaft cylinder 22, so as to realize the drying of refractory materials by the equipment with steam; moreover, two pressure relief valves are arranged on one side of the material distributing wheel 962 where the transmission shaft cylinder 22 is provided, ensuring the normal circulation and pressure relief of the steam in the material distributing wheel 962, and the openings of the pressure relief valves face outward, and the discharged steam has no influence on the refractory materials;

[0067] When the material distributing wheel 962 rotates, due to the accumulation of refractory materials, the force on the material distributing wheel 962 is uneven during rotation, resulting in eccentricity. Therefore, a plurality of fixed connection seats 969 are evenly distributed in a ring shape on the side of the material distributing wheel 962 where the transmission shaft cylinder 22 is welded; the fixed connection seats 969 are movably connected to the tensioners 970 through rotating shafts, and the other ends of the tensioners 970 are fixed on the transmission shaft cylinder 22 through the fixed connection seats 969. The plurality of tensioners 970 are used to ensure that the transmission shaft cylinder 22 and the material distributing wheel 962 are in a relatively stable rotating state, avoiding the occurrence of eccentricity.

[0068] Since the material feeding wheel 962 and the teeth are hollow, when steam enters the material feeding wheel 962, it will fill all the teeth, so that all the teeth can dry the refractory material; and through holes facilitating the flow of the refractory material are provided on all the teeth. Therefore, when the material feeding wheel 962 rotates, a certain tooth picks up the refractory material, but due to the existence of the through holes, the refractory material will flow to the next tooth, and so on. The refractory material flows out from the through holes and then continuously falls on the next tooth, thus forming a state where it can flow back and be agitated, thereby increasing the fluidity of the refractory material and fully increasing the contact area between the refractory material and the teeth and the material feeding wheel 962, so as to achieve the effect of rapid drying and greatly improve the drying efficiency of the refractory material;

[0069] Since the refractory material is in powder form, due to the influence of other factors during the preparation of the refractory material, some granular refractory material will be mixed in the powdered refractory material. During drying, the powdered refractory material will be dried earlier than the granular refractory material. Therefore, a discharge hole 963 is provided on the side of the material feeding wheel 962 close to the outer fixing plate 94. After the powdered refractory material is dried, it will be discharged through the discharge hole 963. At this time, the powder extraction pipe 3 will introduce negative pressure, and under the suction of the negative pressure, it will be sucked into the negative pressure tank for storage;

[0070] After the powdered refractory material is extracted (judged by the flow meter provided on the material extraction pipe 12), the rod of the electric push cylinder 99 extends, and the driving claw 95 is used to slide the driving plate 965 along the fixed shaft 966 inward, so that the material blocking plate 964 passes through the material feeding wheel 962 and fits with the teeth. At this time, the teeth have good agitation when agitating the granular refractory material and can drive a large amount of refractory material to rotate. When it rotates to the discharge port 968, due to the inclined states of both the material blocking plate 964 and the teeth, and in combination with the centrifugal force when the material feeding wheel 962 rotates, the granular refractory material can be discharged from the discharge port 968 and fall into the aggregate member 97. At this time, the negative pressure of the powder extraction pipe 3 is closed, and the negative pressure on the material extraction pipe 12 is turned on, so that the granular refractory material is sucked into the negative pressure aggregate tank; thus, the separation and separate storage of the powdered refractory material and the granular refractory material are realized;

[0071] After the granular refractory material is extracted, the rod of the electric push cylinder 99 retracts, the driving plate 965 returns to its original position along the fixed shaft 966 under the pushing of the spring 967, and the material blocking plate 964 separates from the material feeding wheel 962. Subsequently, the refractory material to be dried is continuously added to the drying assembly 9, so as to realize the non-stop operation of the equipment, greatly saving the waiting time and improving the working efficiency.

[0072] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present invention. Any reference signs in the claims should not be construed as limiting the claims involved.
