Description

Technical Field

[0001] This utility model belongs to the field of mixing technology, specifically relating to a horizontal mixing machine for producing refractory castables. Background Technology

[0002] Refractory castable is a granular or powdered material made by adding a certain amount of binder to refractory materials. It has high fluidity and is an unshaped refractory material formed by casting. Compared with other unshaped refractory materials, refractory castable has a higher binder and moisture content and better fluidity, so it has a wider range of applications. The materials and binders used can be selected according to the application conditions. It can be directly cast into linings or made into precast blocks by casting or vibration compaction.

[0003] Currently, the production process of conventional refractory castables mainly includes raw material processing, batching and mixing, molding and sintering, and quality control. During batching and mixing, the corresponding raw materials need to be accurately weighed according to the formula and fed into mixing equipment such as horizontal mixers. Existing horizontal mixers typically consist of a horizontally rotatable cylinder and an agitator inside the cylinder that rotates in the opposite direction. During mixing, the opposite rotation creates counter-current flow, resulting in low extrusion pressure on the material, low heat generation, high mixing efficiency, and relatively uniform mixing. However, this type of mixer still has the following problems in practical use: 1. The cylinder is a one-piece structure, which is inconvenient for quick loading and unloading of materials and for cleaning and maintenance of the cylinder's interior; 2. The agitator is also a one-piece structure, making it difficult to individually disassemble and replace worn or failed mixing components, resulting in inconvenience and affecting the mixing effect, which needs to be addressed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a horizontal mixer for producing refractory castables, which utilizes a split cylindrical structure to facilitate quick loading and unloading of materials and convenient replacement of the mixing blades, thereby solving the above-mentioned problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a horizontal mixer for producing refractory castables, comprising a base, a cylinder horizontally and rotatably mounted on the base, and a stirrer rotatably mounted inside the cylinder in the opposite direction to the cylinder. The upper part of the cylinder is open and abuts against a cylinder cover. Several fixed seats are fixedly mounted on the front and rear sides of the upper part of the cylinder. A positioning block is fixedly mounted on the fixed seat. A limit block is rotatably connected to the positioning block. A blind hole is opened at one end of the limit block. Several mounting seats are fixedly mounted on the front and rear sides of the lower part of the cylinder cover. A positioning groove is opened through the mounting seat. Several sets of elastic elements are fixedly mounted on the outer wall of the cylinder cover above the mounting seat. The elastic elements on the same side... A locking plate is fixedly connected to the cylinder body. Several insert shafts are fixed on the side of the locking plate away from the elastic element. The mounting base corresponds to and abuts against the fixed base. The positioning block is inserted into the corresponding positioning groove. The limiting block passes through the corresponding positioning groove and presses against the top surface of the mounting base after rotating 90 degrees. The blind hole faces the cylinder cover. The locking plate presses against the limiting block and the insert shaft on it corresponds to and is inserted into the corresponding blind hole. The stirrer includes a stirring shaft coaxial with the cylinder body. Several stirring columns are fixed in the radial direction of the stirring shaft. A stirring sleeve is fitted and screwed onto the outer side of the stirring column. Several square stirring frames are fixed on the outer periphery of the stirring sleeve. A mesh stirring element is fixed on the inner side of the stirring frame.

[0006] Preferably, both the positioning block and the limiting block are adapted to the positioning groove, and a support shaft is fixedly embedded on the top of the positioning block. The top end of the support shaft extends into the limiting block and is rotatably connected to the limiting block through a bearing.

[0007] Preferably, the elastic element consists of a guide telescopic rod and a compression spring fitted on the outside of the guide telescopic rod. One end of the guide telescopic rod and the compression spring are fixedly connected to the outer wall of the cylinder cover, and the other end is fixedly connected to the locking plate.

[0008] Preferably, the insert shaft is adapted to the corresponding blind hole.

[0009] Preferably, a sealing gasket is fixed on the upper port of the cylinder.

[0010] Preferably, the tail end of the stirring column is provided with an internally threaded blind hole, one end of the stirring sleeve is open and the other end is closed, and an externally threaded column is fixed on the inner side of the closed end. The stirring sleeve is inserted into the outside of the stirring column and the externally threaded column is screwed into the corresponding internally threaded blind hole.

[0011] Preferably, a first support seat is vertically fixed on the base on both the left and right sides of the cylinder. A rotating shaft is rotatably provided on the upper part of the two first support seats. The two rotating shafts are coaxially fixedly connected to the left and right sides of the cylinder, and one of the rotating shafts passes through the corresponding first support seat and is connected to a first motor. A through cavity is coaxially opened on the other rotating shaft.

[0012] Preferably, a second support seat is vertically fixed on the side of the base away from the first motor. The stirring shaft extends toward the side away from the first motor and passes through the end wall of the cylinder, the through cavity of the rotating shaft on the same side and the second support seat in sequence, and is then connected to the second motor. The output end of the second motor rotates in the opposite direction to the output end of the first motor. The part of the stirring shaft that passes through the corresponding end wall of the cylinder, the through cavity and the second support seat is rotatably connected to the corresponding end wall of the cylinder, the through cavity and the second support seat.

[0013] Preferably, a handle is fixed on the outer top of the cylinder cover.

[0014] Preferably, a material frame is placed on the base below the cylinder, and a foamed aluminum pad is fixed on the bottom of the base.

[0015] The beneficial effects of this utility model are as follows: During mixing, first turn the open end of the cylinder upwards, and then quickly fill the cylinder with the proportioned materials through the open end. After filling, place the cylinder cover on the open end. When placing it, align the positioning groove with the corresponding positioning block and limiting block, and further compress the elastic element to ensure the positioning groove is unobstructed until the mounting base abuts against the fixing base. At this time, the positioning block is inserted into the corresponding positioning groove, completing the initial positioning and installation of the cylinder cover. At this time, the bottom surface of the limiting block is flush with the top surface of the mounting base. Then, rotate the end of the limiting block with the blind hole 90 degrees toward the cylinder cover so that the limiting block and the positioning block are perpendicular. This allows the limiting block to press against the top surface of the mounting base, thereby pressing and fixing the cylinder cover onto the cylinder, completing the further fixing and installation of the cylinder cover. Next, the locking plate is released. Under the restoring force of the elastic element, the locking plate is automatically springed forward and pressed against the limiting block, causing its insert shaft to engage in the corresponding blind hole, thus locking the limiting block and preventing its rotation, ensuring the cylinder cover is securely fixed. Then, the counter-current mixing of the material is achieved through the opposite rotation of the cylinder and the agitator. The agitator's mixing frame and mesh agitator ensure both mixing force and material flowability, resulting in higher mixing efficiency and quality. After mixing, turn the cylinder cover upwards again. Then, compress the elastic element to move the locking plate away from the limiting block, pull the insert shaft out of the corresponding blind hole, and release the locking of the limiting block. Next, rotate the limiting block 90 degrees to make it parallel to the positioning block, releasing the pressure limiting on the mounting base. Then, remove the cylinder cover to remove it. Turn the open end of the cylinder downwards to quickly pour out the mixed material, completing the unloading. When cleaning and maintenance of the cylinder interior is required later, simply turn the open end upwards again after unloading for easy operation. Thus, the detachable split structure design of the cylinder cover and cylinder body allows for quick loading and unloading before and after mixing, and also facilitates cleaning and maintenance of the cylinder interior. In addition, when the mixing sleeve and its components are worn or broken, the corresponding mixing sleeve can be rotated upwards so that it extends out of the open end when the cylinder is unloaded and the open end is facing upwards. Then, the corresponding mixing sleeve can be quickly unscrewed and replaced by screwing it off through the connection between the mixing sleeve and the mixing column. The operation is simple and can better ensure the mixing effect, making it more convenient and practical overall. Attached Figure Description

Detailed Implementation

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: like Figures 1 to 12As shown, a horizontal mixer for producing refractory castables includes a base 1, a cylinder 2 that is horizontally and rotatably mounted on the base 1, and an agitator that is rotatably mounted inside the cylinder 2 and rotates in the opposite direction to the cylinder 2. The upper part of the cylinder 2 is open and abuts against the cylinder cover 3. Several fixed seats 4 are fixed on the front and rear sides of the upper part of the cylinder 2. A positioning block 5 is fixed on the fixed seat 4. A limit block 6 is rotatably connected to the positioning block 5. A blind hole 7 is opened at one end of the limit block 6. Several mounting seats 8 are fixed on the front and rear sides of the lower part of the cylinder cover 3. A positioning groove 9 is opened through the mounting seat 8. Several sets of elastic elements are fixed on the outer wall of the cylinder cover 3 above the mounting seat 8. The same locking plate 10 is fixedly connected to the elastic elements on the same side. Several insert shafts 11 are fixed on the side of the locking plate 10 away from the elastic elements. The mounting seat 8 corresponds to and abuts against the fixed seat 4. The positioning block 5 is inserted into the corresponding positioning groove 9. The limit block 6 passes through the corresponding positioning groove 9 and presses against the top surface of the mounting seat 8 after rotating 90 degrees. The blind hole faces the cylinder cover 3. The locking plate 10 presses against the limit block 6 and the insert shaft 11 on it corresponds to and is inserted into the corresponding blind hole 7. The agitator includes an agitator shaft 12 coaxial with the cylinder 2. Several agitator columns 13 are fixedly mounted radially on the agitator shaft 12. An agitator sleeve 14 is fitted and screwed onto the outer side of the agitator column 13. Several square agitator frames 15 are fixedly mounted on the outer periphery of the agitator sleeve 14. A mesh agitator 16 is fixedly mounted on the inner side of the agitator frame 15. During mixing, first turn the open end of cylinder 2 upwards, then quickly fill the cylinder 2 with the proportioned material through the open end. After filling, place the cylinder cover 3 on the open end, aligning the positioning groove 9 with the corresponding positioning block 5 and limiting block 6, and further compress the elastic element to ensure the positioning groove 9 is unobstructed until the mounting base 8 abuts against the fixing base 4. At this point, the positioning block 5 is inserted into the corresponding positioning groove 9, completing the initial positioning and installation of the cylinder cover 3. At this point, the bottom surface of the limiting block 6 is flush with the top surface of the mounting base 8. Then, rotate the end of the limiting block 6 with the blind hole 7 towards the cylinder cover 3 by 90 degrees, so that the limiting block 6 is perpendicular to the positioning block 5. This allows the limiting block 6 to press against the top surface of the mounting base 8, thereby pressing and fixing the cylinder cover 3 onto the cylinder 2, completing the further fixing and installation of the cylinder cover 3. Next, the locking plate 10 is released. Under the restoring force of the elastic element, the locking plate 10 is automatically springed forward and pressed against the limiting block 6, causing its insert shaft 11 to be inserted into the corresponding blind hole 7, thus locking the limiting block 6 and preventing its rotation, ensuring the cylinder cover 3 is securely fixed. Afterwards, the material is counter-currently stirred by the opposite rotation of the cylinder 3 and the agitator. The stirring frame 15 and the mesh stirring element 16 on the agitator ensure both stirring force and material flowability, resulting in higher stirring efficiency and quality. After mixing is complete, turn the cylinder cover 3 upwards again. Then, compress the elastic element to move the locking plate 10 away from the limiting block 6, and pull the insert shaft 11 out of the corresponding blind hole 7 to release the lock on the limiting block 6. Then, rotate the limiting block 6 90 degrees to make it parallel to the positioning block 5, releasing the pressure limit on the mounting base 8. Next, move the cylinder cover 3 away to remove it. Then, turn the open end of the cylinder 2 downwards so that the mixed material can be quickly poured out through the open end to complete the unloading. When cleaning and maintenance of the inside of the cylinder 2 is required later, simply turn the open end upwards again after unloading for easy operation. Thus, through the detachable split structure design of the cylinder cover 3 and the cylinder 2, quick loading and unloading can be achieved before and after mixing, and it is also convenient to clean and maintain the inside of the cylinder 2. In addition, when the stirring sleeve 14 and its components are worn or broken, the corresponding stirring sleeve 14 can be rotated to face upwards so that it extends out of the open end when the cylinder 2 is unloaded and the open end is facing upwards. Then, the corresponding stirring sleeve 14 can be quickly unscrewed and replaced by screwing it off through the connection between the stirring sleeve 14 and the stirring column 13. The operation is simple and can better ensure the stirring effect. The whole operation is more convenient and practical.

This allows the locking plate 10 to be guided and limited by the guide telescopic rod 19 during use, and the movement of the locking plate 10 is achieved by the elastic force of the compression spring 20, thereby enabling the insertion, locking, and unlocking of the limiting block 6.
