Description

Technical Field

[0001] The invention relates to a pickling mixing device, in particular to a pickling mixing device for preparing special refractory materials which is applied in the field of preparing special refractory materials. Background Art

[0002] Special refractory materials refer to a group of new materials developed on the basis of traditional ceramics and ordinary refractory materials, sometimes also called high-temperature ceramics or high-temperature materials.

[0003] On the basis of the manufacturing process of traditional refractory materials and traditional ceramics, with reference to the types of high melting point substances and manufacturing processes selected in these materials, improvements and innovations are made in terms of materials, processes, performance and varieties, so as to develop a refractory material with high purity, high melting point, good thermal shock resistance, high temperature strength and density. Including: high melting point oxides (alumina, zirconium oxide, magnesium oxide, fused quartz, spinel, etc.), refractory compounds (carbides, nitrides, borides, silicides, etc.) and metal ceramics (alumina-chromium, alumina-iron, etc.), ceramic coatings (high temperature sintering, flame and plasma spraying, low temperature baking reinforcement, vapor deposition), ceramic fibers and fiber reinforcement materials (boron, carbon, oxides, carbides, nitrides, etc.).

[0004] Refractory raw materials can be simply divided into three parts: one is natural mineral raw materials; the second is artificial synthetic raw materials; the third is auxiliary raw materials. Special refractory materials often use chemical raw materials, and rarely directly use mineral raw materials.

[0005] Natural mineral raw materials can be divided into the following categories according to their mineral phase composition and chemical composition: aluminosilicate, alkali, siliceous, halogenated, carbonaceous, etc. Aluminosilicates include clay, calcite, pyrophyllite, sillimanite, etc.; alkalis include magnesite, dolomite, limestone, etc.; siliceous materials include silica; halogenated materials include zircon; carbonaceous materials include graphite, etc.

[0006] Quartz sand is quartz particles made by crushing quartz stone. Quartz stone is a non-metallic mineral, a hard, wear-resistant, chemically stable silicate mineral, and its main mineral component is SiO2. Quartz sand is widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical industry, plastics, rubber, abrasives, filter materials and other industries.

[0007] At present, the domestic production process of high-purity quartz sand is mainly: crushing - screening - magnetic separation - water washing - acid washing purification - water washing deacidification water washing - dehydration - drying. Each process is set up independently and cannot form an assembly line. The existing quartz sand pickling drum cannot realize automatic feeding and automatic discharging. It is necessary to manually operate the crane to lift the drum. When discharging, the drum needs to be lifted to drain the acid, which is time-consuming and laborious. At the same time, due to the large size of the drum, when the traditional drum rotates, the quartz sand sinks to the bottom of the drum, the stirring is uneven, and the quartz sand is easy to become dense, which makes it difficult for the acid to penetrate into the quartz sand and the impurity removal effect is poor.

[0008] In order to solve the above problems, the Chinese patent CN207192814U specification discloses an automatic pickling device for quartz sand, which belongs to the field of refractory material production. It mainly includes a screening drum, a water washing tank and a pickling tank, which are connected in sequence through a conveying device; the pickling tank is provided with a bracket on both sides, a roller is provided on the bracket, and the roller is densely covered with small holes, a feed port is provided at one end of the roller, and a sealing door is provided on the feed port, and the other end of the roller is closed, and the two sides of the roller are connected to the bracket through supporting rollers, and a rotating rib is fixedly connected inside the roller, and a material-discharging blade is provided at the feed port. The automatic pickling device for quartz sand realizes automatic feeding, pickling and discharging of quartz sand, greatly improving the working effect, and at the same time, preventing the quartz sand from becoming dense, and the impurity removal effect is good. The utility model is mainly used for automatic pickling of quartz sand.

[0009] In the above-mentioned prior art, although the quartz sand in the drum is divided into several parts by adding ribs, the effect of preventing the quartz sand from becoming dense is achieved, but the several parts of quartz sand are still stacked when they come into contact with the pickling solution at the lowest point of the drum, which can easily lead to uneven or insufficient contact between the quartz sand and the pickling solution, affecting the quality of the semi-finished products after pickling. At the same time, although the ribs and the material-discharging blades can also achieve the effect of discharging, the discharging effect is not good. The ribs cannot guide the quartz sand to the feed port (also the discharging port) well, and incomplete discharging is prone to occur, resulting in a certain amount of residual material remaining in the drum. Summary of the invention

[0010] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to design a pickling mixing equipment for preparing special refractory materials that can fully disperse quartz sand so that it can fully contact with the pickling liquid and can also be fully discharged.

[0011] In order to solve the above problems, the present invention provides a pickling mixing device for preparing special refractory materials, comprising a pickling mixing tank rotatably mounted on a support base and a driving motor fixedly mounted on the support base to drive the pickling mixing tank to rotate;

[0012] A feeding port and a discharging port are fixed at the upper and lower ends of the pickling mixing tank, and an angle of less than 180° is formed between the feeding port and the discharging port. A sealing cover is provided on the feeding port and the discharging port, and an extended cover body is extended from the sealing cover and plugged in the feeding port or the discharging port. The inner wall of the extended cover body has the same curvature as the inner wall of the pickling mixing tank;

[0013] A plurality of material-dispensing blades are fixed in the pickling mixing tank, and the plurality of material-dispensing blades are distributed in the pickling mixing tank along the circumference of the central axis of the pickling mixing tank. The material-dispensing blades are bent and extended along the axial direction of the pickling mixing tank, and hydrophobic teeth are arranged on the material-dispensing blades, and an opening is formed at one end of the hydrophobic teeth away from the inner wall of the pickling mixing tank;

[0014] An arc plate is movably mounted between the two ends of the pickling mixing tank. The arc plate is coaxially arranged with the pickling mixing tank. Both ends of the arc plate extend out of the pickling mixing tank and are slidably connected to the support seat through a connecting piece. The sliding direction is the same as the axial direction of the pickling mixing tank.

[0015] The arc plate is installed at the bottom of the pickling mixing tank to form a cutting blade with a fan-shaped cross section. The cutting blade is provided with multiple cutting blades and is staggered with multiple hydrophobic teeth respectively. The gaps between the multiple cutting blades are used for the material-dispensing blade to move through;

[0016] A guide structure is provided in the pickling mixing tank to drive the installation arc plate to reciprocate along the axial direction. When the material-dispensing blade intersects with the installation arc plate, the guide structure drives the installation arc plate to reset and keep it in the same position.

[0017] In the pickling mixing equipment for preparing the above-mentioned special refractory materials, firstly, a feeding port and a discharging port are arranged at the upper and lower ends of the pickling mixing tank, which is conducive to feeding or discharging when the pickling mixing tank stops. Since the discharging port is located at the lower end of the pickling mixing tank and forms an angle of less than 180° with the feeding port, the discharging port is inclined outward, which is more convenient for discharging, and ensures that the pickled special refractory semi-finished product can be completely taken out;

[0018] Secondly, by arranging the hydrophobic teeth on the material-diverting blade, the pickling liquid in the raw material can be controlled out while the raw material is diverted, and it can also cooperate with the cutting blade. When the previous material-diverting blade and the cutting blade are staggered, the raw material on the previous material-diverting blade is intercepted by the cutting blade, and thus stays at one end of the cutting blade. After the previous material-diverting blade leaves, as the pickling mixing tank rotates, the guide structure drives the installation arc plate and the cutting blade to move back and forth linearly along the axis of the pickling mixing tank, so that the intercepted raw material enters the space between the cutting blades during the left and right swinging of the cutting blade. In the gap, the raw material is confined between the two cutting blades, and is restricted to form a fan-shaped pile that conforms to the shape of the cutting blades during repeated swinging, so that the raw material will not form an accumulation at the bottom, and the raw material can be more fully in contact with the pickling liquid, further improving the pickling effect. Afterwards, the raw material is also intercepted when the next material-dividing blade intersects with the cutting blade, but the next material-dividing blade drives the raw material intercepted by the previous material-dividing blade in the gap between multiple cutting blades when it intersects with the cutting blade, thereby taking away the pickled raw material and completing the pickling operation of the raw material.

[0019] As a further supplement to the present application, both sides of the pickling mixing tank are integrally formed with end heads, and a sealing member for closing the end heads is installed in the end heads;

[0020] The guiding structure includes:

[0021] A guide groove, which is provided on the inner side wall of the end portion;

[0022] A driven shaft, the driven shaft is mounted on the lower end of the mounting arc plate extending to the end portion, and the driven shaft is movably embedded in the guide groove;

[0023] When the pickling mixing tank rotates, the guide groove drives the driven shaft to reciprocate along the axial direction of the pickling mixing tank or remain in place alternately. When the driven shaft remains in place, the material-dispensing blade intersects with the mounting arc plate.

[0024] As a further supplement to the present application, the guide groove includes a straight groove section and a corrugated groove section, the straight groove section and the corrugated groove section are both provided with a plurality of sections, the number of the straight groove section and the corrugated groove section are the same as the number of the material-dispensing blades, and the cross-sectional curvature of the straight groove section is consistent with the cross-sectional curvature of the mounting arc plate;

[0025] The directions of the crests and troughs of the corrugated groove section are consistent with the axial direction of the pickling mixing tank.

[0026] As a further supplement to the present application, the corrugated groove segment is a corrugated groove with a gradually changing wavelength, the middle portion of the corrugated groove segment has a longer wavelength, and the end portion where the corrugated groove segment is connected to the straight groove segment has a shorter wavelength.

[0027] As a further supplement to the present application, the driven shaft is rotatably connected to the lower end of the mounting arc plate, and the axis of the driven shaft is the same as the radial direction of the pickling mixing tank.

[0028] As a further supplement to the present application, pads are movably connected inside the end portions of the pickling mixing tank, and the pads and the mounting arc plates together form a cylindrical body, and the pads and the mounting arc plates are movably connected, and an extension boss is extended outward from the outer side of the part of the pad located inside the pickling mixing tank, and the outer side wall of the extension boss is slidably fitted with the end of the material-discharging blade away from the inner wall of the pickling mixing tank.

[0029] As a further supplement to the present application, the installation arc plate and the pad are both arc-shaped mesh plate structures provided with mesh holes, and the outer side walls of the installation arc plate and the pad located at the end head are both sealed and rotatably connected with the inner side wall of the end head;

[0030] The sealing member comprises a sealing plate, the peripheral side of which is fixed to the inner side of the mounting arc plate or the inner side of the backing plate to form a seal;

[0031] A packing regulating tube is fixed and connected to the sealing plate at one end. The packing regulating tube is used to add pickling liquid into the pickling mixing tank when the pickling mixing tank rotates, or to add the required atmosphere into the pickling mixing tank, or to install a temperature regulating device for regulating the temperature in the pickling mixing tank.

[0032] As a further supplement to the present application, the connecting member includes a fixed support ring, which is fixedly sleeved on the end of the pad, and the fixed support ring is slidably sleeved with the end of the mounting arc plate, and the lower end of the fixed support ring is fixed to the upper end of the support seat;

[0033] A plurality of driven wheels are installed on the upper end of the support seat, and a driven sleeve wheel is provided on the fixed sleeve outside the end head. The plurality of driven wheels are in rolling contact with and support the driven sleeve wheel, and the output shaft of the driving motor drives one of the driven wheels to rotate through the driving wheel.

[0034] In summary, firstly, the feeding port and the discharging port are arranged at the upper and lower ends of the pickling mixing tank, which is conducive to feeding or discharging when the pickling mixing tank stops. Since the discharging port is located at the lower end of the pickling mixing tank and forms an angle less than 180° with the feeding port, the discharging port is inclined outward, which is more convenient for discharging and ensures that the semi-finished special refractory material after pickling can be completely taken out;

[0035] Secondly, by arranging the hydrophobic teeth on the material-diverting blade, the pickling liquid in the raw material can be controlled out while the raw material is diverted, and it can also cooperate with the cutting blade. When the previous material-diverting blade and the cutting blade are staggered, the raw material on the previous material-diverting blade is intercepted by the cutting blade, and thus stays at one end of the cutting blade. After the previous material-diverting blade leaves, as the pickling mixing tank rotates, the guide structure drives the installation arc plate and the cutting blade to move back and forth linearly along the axis of the pickling mixing tank, so that the intercepted raw material enters the space between the cutting blades during the left and right swinging of the cutting blade. In the gap, the raw material is confined between the two cutting blades, and is restricted to form a fan-shaped pile that conforms to the shape of the cutting blades during repeated swinging, so that the raw material will not form an accumulation at the bottom, and the raw material can be more fully in contact with the pickling liquid, further improving the pickling effect. Afterwards, the raw material is also intercepted when the next material-dividing blade intersects with the cutting blade, but the next material-dividing blade drives the raw material intercepted by the previous material-dividing blade in the gap between multiple cutting blades when it intersects with the cutting blade, thereby taking away the pickled raw material and completing the pickling operation of the raw material.

[0046] An implementation method of the present application is described in detail below with reference to the accompanying drawings.

[0047] The first implementation method:

[0048] The present invention provides a pickling mixing equipment for preparing special refractory materials. Figure 1-Figure 3 as well as Figure 8 , including a pickling mixing tank 1 rotatably mounted on a support base 2 and a driving motor 3 fixedly mounted on the support base 2 to drive the pickling mixing tank 1 to rotate;

[0049] A feeding port 101 and a discharging port 102 are fixed at the upper and lower ends of the pickling mixing tank 1. An angle less than 180° is formed between the feeding port 101 and the discharging port 102. A sealing cover 103 is provided on the feeding port 101 and the discharging port 102. An extended cover body 1031 is extended from the sealing cover 103 and plugged into the feeding port 101 or the discharging port 102. The inner side wall of the extended cover body 1031 has the same curvature as the inner side wall of the pickling mixing tank 1.

[0050] A plurality of material-dispensing blades 4 are fixed in the pickling mixing tank 1. The plurality of material-dispensing blades 4 are distributed in the pickling mixing tank 1 along the circumference of the central axis of the pickling mixing tank 1. The material-dispensing blades 4 are bent and extended along the axial direction of the pickling mixing tank 1. The material-dispensing blades 4 are provided with hydrophobic teeth 401. The hydrophobic teeth 401 are opened at one end away from the inner wall of the pickling mixing tank 1.

[0051] An arc plate 5 is movably mounted between the two ends of the pickling mixing tank 1. The arc plate 5 is coaxially arranged with the pickling mixing tank 1. Both ends of the arc plate 5 extend out of the pickling mixing tank 1 and are slidably connected to the support seat 2 through a connecting piece. The sliding direction is the same as the axial direction of the pickling mixing tank 1.

[0052] The arc plate 5 is installed at the bottom of the pickling mixing tank 1 to form a cutting blade 501 with a fan-shaped cross section. The cutting blade 501 is provided with a plurality of cutting blades and is staggered with a plurality of hydrophobic teeth 401. The gaps between the plurality of cutting blades 501 allow the material-dispensing blade 4 to move through.

[0053] A guide structure is provided in the pickling mixing tank 1 to drive the installation arc plate 5 to reciprocate along the axial direction. When the material-dispensing blade 4 intersects with the installation arc plate 5, the guide structure drives the installation arc plate 5 to reset and keep it at the same position.

[0054] Based on the above structure, firstly, a feeding port 101 and a discharging port 102 are arranged at the upper end and the lower end of the pickling mixing tank 1, which is conducive to feeding or discharging when the pickling mixing tank 1 stops. Since the discharging port 102 is located at the lower end of the pickling mixing tank 1 and forms an angle less than 180° with the feeding port 101, it is more convenient to discharging materials when the discharging port 102 is inclined outward, so as to ensure that the semi-finished special refractory material after pickling can be completely taken out;

[0055] Secondly, by arranging the hydrophobic teeth 401 on the material-pickling blade 4, the pickling liquid in the raw material can be controlled out while the raw material is being pried out, and the material-cutting blade 501 can also be cooperated with. When the previous material-pickling blade 4 and the material-cutting blade 501 are interlaced, the raw material on the previous material-pickling blade 4 is intercepted by the material-cutting blade 501, and thus stays at one end of the material-cutting blade 501. After the previous material-pickling blade 4 leaves, as the pickling mixing tank 1 rotates, the guide structure drives the installation arc plate 5 and the material-cutting blade 501 to move back and forth linearly along the axis of the pickling mixing tank 1, so that the intercepted raw material enters the material-cutting blade 501 during the left and right swinging process. In the gap between 501, the raw material is confined between the two cutting leaves 501, and is confined to form a fan-shaped pile that conforms to the shape of the cutting leaves 501 during the repeated swinging process, so that the raw material will not form an accumulation at the bottom, and the raw material can be more fully in contact with the pickling liquid, further improving the pickling effect. Afterwards, the raw material is also intercepted when the rear material-dividing leaf 4 intersects with the cutting leaf 501, but the rear material-dividing leaf 4 drives the raw material intercepted by the previous material-dividing leaf 4 in the gap between the multiple cutting leaves 501 when it intersects with the cutting leaf 501, thereby taking away the pickled raw material and completing the pickling operation of the raw material.

[0056] Figure 5-Figure 7 As shown, both sides of the pickling mixing tank 1 are integrally formed with end heads 104, and a sealing member for closing the end heads 104 is installed in the end heads 104;

[0057] The guiding structure includes:

[0058] A guide groove 105, which is formed on the inner wall of the end portion 104;

[0059] A driven shaft 502, the driven shaft 502 is mounted on the lower end of the portion of the mounting arc plate 5 extending to the end portion 104, and the driven shaft 502 is movably embedded in the guide groove 105;

[0060] When the pickling mixing tank 1 rotates, the guide groove 105 drives the driven shaft 502 to move back and forth along the axial direction of the pickling mixing tank 1 or to remain in place alternately. When the driven shaft 502 remains in place, the material-dispensing blade 4 intersects with the mounting arc plate 5.

[0061] The guide groove 105 includes a straight groove section 1051 and a corrugated groove section 1052. The straight groove section 1051 and the corrugated groove section 1052 are both provided with a plurality of sections. The number of the straight groove sections 1051 and the corrugated groove sections 1052 is the same as the number of the material-dispensing blades 4. The cross-sectional curvature of the straight groove section 1051 is consistent with the cross-sectional curvature of the mounting arc plate 5.

[0062] The crests and troughs of the corrugated groove section 1052 are oriented in the same direction as the axial direction of the pickling mixing tank 1 .

[0063] When the pickling mixing tank 1 rotates, the mounting arc plate 5 does not rotate, so that the corrugated groove section 1052 drives the driven shaft 502 to reciprocate along the axial direction of the pickling mixing tank 1, and when the straight groove section 1051 coincides with the driven shaft 502, the driven shaft 502 remains in place. This is also when the material-discharging blade 4 intersects with the mounting arc plate 5, thereby ensuring that the material-discharging blade 4 can smoothly produce an interlaced relative movement with the material-cutting blade 501, so as to achieve the effect that the material-cutting blade 501 can intercept the raw materials transported by the material-discharging blade 4, and the material-discharging blade 4 can take away the semi-finished products after pickling.

[0064] Among them, the corrugated groove section 1052 is a corrugated groove with a gradually changing wavelength. The middle wavelength of the corrugated groove section 1052 is longer, and the wavelength of the end portion where the corrugated groove section 1052 is connected to the straight groove section 1051 is shorter. Through the gradually changing wavelength setting, the corrugated groove section 1052 can drive the cutting blade 501 to produce a changing swinging effect, thereby ensuring that the raw material produces a swing with a changing frequency, and has a better contact with the pickling liquid, thereby enhancing the pickling effect and improving the pickling efficiency.

[0065] Among them, the driven shaft 502 is rotatably connected to the lower end of the mounting arc plate 5, and the axis of the driven shaft 502 is the same as the radial direction of the pickling mixing tank 1. When the driven shaft 502 is rotated, the friction between the driven shaft 502 and the inner wall of the guide groove 105 can be reduced, thereby extending the service life of the guide structure and reducing equipment loss.

[0066] Figure 2-Figure 3 As shown, pads 6 are movably connected in the end portions 104 of the pickling mixing tank 1, and the pads 6 and the mounting arc plates 5 together form a cylindrical body, and the pads 6 and the mounting arc plates 5 are movably connected, and an extension boss 601 is extended outwardly from the outer side of the pads 6 located in the pickling mixing tank 1, and the outer side wall of the extension boss 601 is slidably fitted with the end of the material-dispensing blade 4 away from the inner wall of the pickling mixing tank 1;

[0067] By setting the pad 6, a complete cylindrical structure can be formed with the installation arc plate 5, and the movable direction of the installation arc plate 5 can be limited to avoid bending and deviation of the installation arc plate 5 due to force. At the same time, the outwardly protruding extension boss 601 can cooperate with the material-shifting blade 4 to ensure that the raw material driven by the material-shifting blade 4 is always between the two material-shifting blades 4, thereby avoiding the raw material between the two material-shifting blades 4 from falling when moving to the upper end of the pickling mixing tank 1, resulting in excessive pickling of the raw material.

[0068] Figure 2-Figure 4 As shown, the installation arc plate 5 and the pad plate 6 are both arc-shaped mesh plate structures provided with mesh holes, and the outer side walls of the installation arc plate 5 and the pad plate 6 located at the end portion 104 are both sealed and rotatably connected with the inner side wall of the end portion 104;

[0069] The sealing member comprises a sealing plate 7, the peripheral side of the sealing plate 7 is fixed to the inner side of the mounting arc plate 5 or the inner side of the backing plate 6 to form a seal;

[0070] A filler regulating pipe 701 is also fixed and connected to the sealing plate 7 at one end thereof, and the filler regulating pipe 701 is used to add pickling liquid into the pickling mixing tank 1 when the pickling mixing tank 1 rotates, or to add the required atmosphere into the pickling mixing tank 1, or to install a temperature regulating device for regulating the temperature in the pickling mixing tank 1;

[0071] By setting the sealing plate 7, the two ends of the pickling mixing tank 1 can be blocked to prevent the entry of debris during pickling. At the same time, by setting the filler regulating tube 701, pickling liquid can be added at any time during the pickling process, or the required atmosphere can be added to the pickling mixing tank 1, or the temperature regulating device can be used to adjust the pickling environment temperature in the pickling mixing tank 1, thereby creating a better pickling environment and further improving the pickling effect. At the same time, the controllability and flexibility of the pickling mixing equipment used for the preparation of special refractory materials are improved, and the use effect is better.

[0072] Figure 1 , Figure 2 and Figure 4 As shown, the connecting member includes a fixed support ring 201, which is fixedly sleeved on the end of the pad 6, and the fixed support ring 201 is slidably sleeved with the end of the mounting arc plate 5, and the lower end of the fixed support ring 201 is fixed to the upper end of the support seat 2;

[0073] A plurality of driven wheels 301 are installed on the upper end of the support seat 2, and a driven sleeve wheel 302 is fixedly sleeved on the outer side of the end head 104. The plurality of driven wheels 301 are in rolling contact with and support the driven sleeve wheel 302. The output shaft of the drive motor 3 drives one of the driven wheels 301 to rotate through the drive wheel. The rotation of one of the driven wheels 301 drives the pickling mixing tank 1 to rotate, and the other driven wheels 301 rotate accordingly, thereby disturbing the raw materials for pickling.

[0074] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
