Description

Technical Field

[0001] The utility model relates to the field of auxiliary components for refractory clay production, in particular to a refractory clay dividing device. Background Art

[0002] Refractory mortar is an amorphous refractory material used as the joints of refractory masonry, also known as jointing material. Refractory mortar can be divided into hydraulic, thermosetting and air-hardening refractory mortars according to the coagulation and hardening characteristics of its binder. Hydraulic refractory mortar uses cement as a binder and can be used at room temperature or in places where it may be in frequent contact with water or water vapor; thermosetting refractory mortar is often made of thermosetting binders such as phosphoric acid or phosphates. After hardening, this type of mortar has high strength at various temperatures, small shrinkage, tight joints and strong corrosion resistance; air-hardening refractory mortar is often prepared with air-hardening binders such as sodium silicate. This type of mortar can make the joints of masonry tight.

[0003] Specifically in the production process of refractory clay, the refractory clay usually needs to be segmented after being extruded by an extruder. At present, when the extruded refractory clay is segmented, it is usually performed by manually cutting with a saw blade or a blade held manually. This segmentation operation method is firstly inefficient, and workers are prone to accidental injuries during the operation, resulting in certain inconveniences in the segmentation operation of the refractory clay.

The outer periphery of the connecting sleeve is fixed with the cutting wing plate extending radially outward along the motor shaft, and the rear end face of the cutting wing plate is flush with the front end face of the mud extrusion tube.

[0009] Preferably, the driving motor is a reduction motor, the cutting wing plate is a rectangular thin plate, and the rotating surface covers the entire front end surface of the mud extrusion tube.

[0010] Preferably, a protective shield is fixedly mounted on the front of the mounting support, and the motor shaft passes through the protective shield in a sliding fit. The protective shield is an arc-shaped shield, and the front and the side close to the mud extrusion tube are open.

[0014] Preferably, a plurality of legs for raising and supporting are vertically fixed around the bottom surface of the extruder body.

[0015] The above-mentioned refractory clay dividing device is used, specifically in the process of dividing the refractory clay extruded through the extruder body, since the front part of the extruder body is provided with the rotating dividing assembly at a position beside the clay extrusion tube, the motor shaft of the rotating dividing assembly drives the cutting wing plate to rotate so that the cutting wing plate can reciprocate through the front end of the clay extrusion tube, thereby the cutting wing plate reciprocates through the front end of the clay extrusion tube to perform a cyclic dividing operation on the extruded refractory clay, replacing the manual dividing operation mode, which is beneficial to improving the dividing efficiency of the refractory clay. Specifically, during operation, the driving motor is driven to rotate. The machine is powered on by being electrically connected to an external power supply cable, and the driving motor drives the connecting sleeve to rotate through the motor shaft. During the rotation, the connecting sleeve drives the cutting wing plate to reciprocate and circulate through the front end of the mud extrusion tube, so as to perform a cyclical segmentation operation on the refractory mud extruded through the mud extrusion tube. Since the protective shield is installed at the front of the mounting support and the protective shield is coaxially arranged on the periphery of the motor shaft, the protective shield can be set to shield the edge position of the cutting wing plate when the cutting wing plate rotates away from the mud extrusion tube, so as to avoid the cutting wing plate being exposed during the rotation process.

Specifically, when the mounting bracket and the rotating splitting component are assembled and disassembled at the front of the extruder body, when assembled, the mounting bracket and the rotating splitting component can be detachably fixed to the front of the extruder body and located beside the mud extrusion tube by means of longitudinal sliding cooperation between the matching plate and the matching groove and vertical sliding cooperation between the limiting rod and the limiting hole. The fixed assembly method of the mounting bracket and the rotating splitting component at the front of the extruder body is simple and easy to implement, which makes it easy to assemble the mounting bracket and The rotating splitting assembly is combined at the front of the extruder body to perform a splitting operation on the refractory clay. When performing the splitting operation, ensure that the rotating splitting assembly is in a stopped state. It is only necessary to hold the handles in the upper and lower positions and pull them outward and allow the limit rods to be pulled out of the limit holes by stretching the springs. Then, the mating plate can be slid longitudinally out of the mating groove to remove the mounting support and the rotating splitting assembly from the front of the extruder body. The method of disassembling the mounting support and the rotating splitting assembly at the front of the extruder body is simple and easy to implement, which facilitates the later inspection, maintenance and thorough cleaning of the mounting support and the rotating splitting assembly after they are disassembled.

Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

Specifically, the rotary dividing assembly 2 includes a driving motor 205 and a cutting wing plate 204. The driving motor 205 is fixed to the back of the mounting bracket 4 along the longitudinal direction, and the motor shaft 202 in front of the driving motor 205 is arranged longitudinally. The mounting support 4 is passed through in a sliding manner and a connecting sleeve 203 is coaxially fixed to the front end. The outer periphery of the connecting sleeve 203 is fixed with a cutting wing plate 204 extending radially outward along the motor shaft 202, and the rear end face of the cutting wing plate 204 is flush with the front end face of the mud extrusion tube 102. The purpose of this arrangement is that the cutting wing plate 204 can be driven to rotate by the motor shaft 202 of the rotating splitting component 2 so that the cutting wing plate 204 can reciprocate through the front end of the mud extrusion tube 102, thereby enabling the extruded refractory mud to be cyclically split.

[0034] See also Figures 1-6As shown, the upper and lower positions on the back of the mounting support 4 are both installed with a disassembly assembly 3, the disassembly assembly 3 is partially fixed to the front of the extruder body 1, and the mounting support 4 and the rotating splitting assembly 2 are detachably fixed to the front of the extruder body 1 through the disassembly assembly 3. Specifically, the disassembly assembly 3 includes a matching plate 305 and a fixing seat 303. The upper and lower positions on the back of the mounting support 4 are both longitudinally fixed with matching plates 305. The outer end faces of the matching plates 305 at the upper and lower positions that are away from each other are vertically provided with limiting holes 308. The extruder body A fixing seat 303 is fixed longitudinally at the upper position behind the mounting support 4 in the front of the body 1, and a matching groove 304 is longitudinally opened in the front of the fixing seat 303. The matching groove 304 corresponds to the matching plate 305 one by one and slides in the longitudinal direction. The outer end surfaces of the fixing seats 303 at the upper and lower positions, which are away from each other, are vertically opened with mounting holes 307. The mounting holes 307 are vertically connected to the corresponding matching grooves 304, and the mounting holes 307 are vertically coaxial with the corresponding limiting holes 308. The mounting holes 307 slide in the vertical coaxial direction to fit the limiting rod 306. The inner ends of the upper and lower limit rods 306 that are close to each other are vertically slidably matched with the corresponding limit holes 308, and the outer ends of the upper and lower limit rods 306 that are away from each other extend out of the outer end surface of the corresponding fixing seat 303 and are coaxially fixed with the handle 301. The part of the limit rod 306 located between the corresponding handle 301 and the outer end surface of the fixing seat 303 is coaxially fitted with a spring 302, and the two ends of the spring 302 are fixedly connected to the corresponding handle 301 and the outer end surface of the fixing seat 303 respectively. The purpose of this arrangement is to 04 The longitudinal sliding fit and the vertical sliding fit of the limit rod 306 and the limit hole 308 can detachably fix the mounting support 4 and the rotating splitting component 2 at the front of the extruder body 1 and locate them beside the slurry extrusion tube 102. At the same time, only the limit rod 306 needs to be pulled out of the limit hole 308 to make the matching plate 305 longitudinally disengage from the matching groove 304 and remove the mounting support 4 and the rotating splitting component 2 from the front of the extruder body 1. The combination and disassembly of the mounting support 4 and the rotating splitting component 2 at the front of the extruder body 1 are simple and easy to implement.

[0035] See also Figures 1-6As shown, the rotating splitting component 2, the disassembly and assembly component 3 and the extruder body 1 are optimized as follows. Specifically, for the rotating splitting component 2, the driving motor 205 is a reduction motor, the cutting wing plate 204 is a rectangular thin plate and the rotating surface covers the entire front end surface of the mud extrusion tube 102. This arrangement ensures that the cutting wing plate 204 can smoothly complete the splitting operation of the refractory mud extruded through the mud extrusion tube 102 during the turnover process. At the same time, optionally, a protective shield 201 is fixedly installed in front of the mounting support 4, and the motor shaft 202 passes through the protective shield 201 in a sliding fit. The protective shield 201 is an arc-shaped shield, and the front and the side close to the mud extrusion tube 102 are open. At the same time, the inner diameter of the protective shield 201 is not less than the rotation diameter of the cutting wing 204. Preferably, the arc length of the protective shield 201 should be greater than half a circle. If it is set in this way, the edge position of the cutting wing 204 can be shielded and protected when it rotates away from the mud extrusion tube 102 through the setting of the protective shield 201, thereby avoiding the cutting wing 204 from exposing the outside of the extruder body 1 during the rotation process, thereby preventing accidental injury to workers.

[0036] Specifically, regarding the assembly and disassembly component 3, the cross-sectional shapes of the mating plate 305 and the mating slot 304 along the transverse vertical plane are both rectangular, so that the mating plate 305 has a good positioning and guiding design when sliding longitudinally along the mating slot 304. At the same time, the mating slot 304 is optionally a blind slot in the longitudinal direction, and the rear end of the mating plate 305 is in contact with the rear end of the corresponding mating slot 304. With this arrangement, when the mating plate 305 slides longitudinally along the mating slot 304, when the limiting hole 308 slides longitudinally with the mating plate 305 to be vertically coaxial with the limiting rod 306, a clear prompt can be provided by the rear end of the mating plate 305 being in contact with the rear end of the corresponding mating slot 304. Specifically, regarding the extruder body 1, a plurality of support legs 101 for supporting the extruder body 1 can be vertically fixed around the bottom surface of the extruder body 1. Such an arrangement facilitates the use of the support legs 101 to elevate the fuselage of the extruder body 1, thereby ensuring that the rotating splitting component 2 can be smoothly installed without interfering with the ground.

[0037] With the above structure, specifically in the process of dividing the refractory clay extruded by the extruder body 1, since the front part of the extruder body 1 is provided with a rotary dividing assembly 2 at the position beside the clay extrusion tube 102, the motor shaft 202 of the rotary dividing assembly 2 drives the cutting wing plate 204 to rotate so that the cutting wing plate 204 can reciprocate through the front end of the clay extrusion tube 102, thereby the cutting wing plate 204 reciprocates through the front end of the clay extrusion tube 102 to perform a cyclic dividing operation on the extruded refractory clay, replacing the manual dividing operation mode, which is beneficial to improving the dividing efficiency of the refractory clay. Specifically, during the operation, the driving motor 205 is driven by The drive motor 205 drives the connecting sleeve 203 to rotate through the motor shaft 202. The connecting sleeve 203 drives the cutting wing plate 204 to rotate back and forth during the rotation and circulates through the front end of the mud extrusion tube 102, so as to perform a cyclical segmentation operation on the refractory mud extruded through the mud extrusion tube 102. Since a protective shield 201 is installed at the front of the mounting bracket 4, and the protective shield 201 is coaxially arranged on the periphery of the motor shaft 202, the protective shield 201 can be set to shield the edge position of the cutting wing plate 204 when the cutting wing plate 204 rotates away from the mud extrusion tube 102, thereby avoiding the cutting wing plate 204 from rotating. During the turnover process, the outer side of the extruder body 1 is exposed to prevent accidental injuries to workers, which is conducive to improving the safety performance of the rotary splitting component 2. Specifically, when the mounting bracket 4 and the rotary splitting component 2 are assembled and disassembled at the front of the extruder body 1, when assembling, the mounting bracket 4 and the rotary splitting component 2 can be detachably fixed to the front of the extruder body 1 and located beside the mud extrusion tube 102 by means of the longitudinal sliding fit between the matching plate 305 and the matching groove 304 and the vertical sliding fit between the limiting rod 306 and the limiting hole 308. The fixed assembly method of the mounting bracket 4 and the rotary splitting component 2 at the front of the extruder body 1 is simple and easy to implement, which makes it easy to install The mounting support 4 and the rotating splitting component 2 are combined at the front of the extruder body 1 to perform the splitting operation on the refractory clay. When performing the splitting operation, ensure that the rotating splitting component 2 is in the shutdown state. It is only necessary to hold the upper and lower handles 301 and pull them outward and allow the spring 302 to be stretched to make the limit rods 306 disengage from the limit holes 308. Then, the matching plate 305 can be slid longitudinally out of the matching groove 304 to remove the mounting support 4 and the rotating splitting component 2 from the front of the extruder body 1. The method of disassembling the mounting support 4 and the rotating splitting component 2 at the front of the extruder body 1 is simple and easy to implement, which makes it convenient to disassemble the mounting support 4 and the rotating splitting component 2 for inspection, maintenance and thorough cleaning later.
