On the other hand, it can realize the self-desilting of the hopper when it is working and reduce the mud adhesion and mud load on the inner wall of the hopper through the self-scraping mud structure in the hopper. At the same time, when the lifting equipment is working, it can also realize the air-clearing mud removal of the hopper, thereby maintaining the service life of the equipment and realizing the self-maintenance of the equipment.

[0019] 2. In the present invention, during cement lifting operation, the power motor outputs the speed at a set power. After the power motor outputs the speed, two cams, two passive wheels and two elastic tensile members are set, so that the lifting shell can reciprocate and vibrate within the set stroke. The vibration state of the lifting shell occurs, on the one hand, the cement can be evenly vibrated and distributed in the hopper in the lifting state, thereby improving the load uniformity of the hopper for the lifted cement. By improving the load uniformity, the service life of the lifting equipment is effectively improved. On the other hand, when the cement is in the unloading state, the vibration state setting of the lifting shell can effectively improve the unloading efficiency of the cement from the unloading slope. At the same time, after the cement is discharged, the vibration state setting of the hopper and the lifting shell can effectively provide the removal strength and removal efficiency of the residual cement on the hopper, thereby reducing the residual rate of cement on the hopper and maintaining the single lifting capacity of the hopper, thereby improving the lifting efficiency of the cement by the lifting equipment and reducing the interference load when the lifting equipment is working;

[0020] 3. In the present invention, the coaxial counter-rotation state of the core shaft and the horizontal stirring tube occurs, so that the horizontal stirring tube and the vertical stirring rod can finally rotate at a set speed during the revolution. The revolution and rotation of the vertical stirring rod can effectively improve the dispersion and clarity of the cement in the hopper, thereby reducing the agglomeration and coagulation rate of the cement during the lifting process. The reduction of the cement agglomeration and coagulation rate can reduce the residual and adhesion rate of the cement in the hopper. On the other hand, the heat in the semi-processed cement clinker can be fully and quickly dissipated, thereby facilitating the subsequent processing of the cement clinker.

[0021] 4. In the present invention, when the flat stirring tube rotates, it drives the half-gear to rotate. After the half-gear rotates, the meshing connection setting between the half-gear and the pinion and the torsion spring setting on the reciprocating screw rod enable the reciprocating screw rod to reciprocate forward and reverse within a set period. By realizing the reciprocating forward and reverse effect of the reciprocating screw rod within the set period, the two scrapers can reciprocate synchronously close to or reciprocate synchronously away from each other. By reciprocating the approach and distance of the two scrapers, the cement adhered to the inner wall of the hopper can be scraped off. By realizing the reciprocating scraping effect of cement, the self-cleaning operation during the cement lifting process of the hopper can be realized.

[0022] 5. In the present invention, when the power motor is working, the air cleaning pump works periodically.

[0035] like Figure 1-Figure 10A lifting device for cement processing shown in the figure comprises a carrier 1, on which a transmission component is mounted, and on which a lifting shell 2 which can reciprocate up and down is connected in a transmission manner;

[0036] It also includes a single chip computer 13 installed on the carrier 1, a feed box 14 is connected to the lower part of the lifting shell 2, a discharge nozzle 15 is connected to the upper part of the lifting shell 2, and a mortar discharge pipe 16 is connected to the bottom of the lifting shell 2;

[0037] The feed box 14 and the discharge nozzle 15 are respectively arranged on two sides of the lifting shell 2;

[0038] During operation, the cement to be lifted is put into the lifting shell 2 through the feed box 14. When the lifting component lifts the cement to a set height, the lifted cement is discharged through the discharge nozzle 15 under the action of gravity, and then the cement is lifted upward. After the cement is discharged through the discharge nozzle 15, the residual cement and the missed cement on the hopper 5 are discharged through the mud discharge pipe 16.

[0039] A lifting component driven by a transmission component is installed in the lifting shell 2, and an annular lifting belt 3 and an annular toothed belt 4 are connected to the lifting component for transmission, and the annular lifting belt 3 and the annular toothed belt 4 rotate in opposite directions;

[0040] The transmission component includes a wheel shaft 17 rotatably connected to the carrier 1 and a power motor 18 fixedly installed on the carrier 1. The output shaft end of the power motor 18 is connected to the wheel shaft 17 through a first belt. Two cams 19 are installed on the wheel shaft 17. A passive wheel 20 is installed on both sides of the lifting shell 2. The two cams 19 are respectively adapted to be connected with the two passive wheels 20. Two groups of symmetrically arranged elastic tensile members 21 are installed between the lifting shell 2 and the carrier 1.

[0041] Each elastic tensile member 21 comprises a T-shaped guide rod mounted on the lifting shell 2, the T-shaped guide rod is slidably connected to the carrier 1, and a limit spring is sleeved on the T-shaped guide rod and is limited by the carrier 1;

[0042] During cement lifting operation, the power motor 18 outputs the speed at the set power. After the power motor 18 outputs the speed, the two cams 19, the two passive wheels 20 and the two elastic tensile members 21 are set, so that the lifting shell 2 can reciprocate and vibrate within the set stroke. The vibration state of the lifting shell 2 occurs, on the one hand, the cement can be evenly vibrated and distributed in the hopper 5 in the lifting state, thereby improving the load uniformity of the hopper 5 for the lifted cement. By improving the load uniformity, the service life of the lifting equipment is effectively improved. On the other hand, when the cement is in the unloading state, the vibration state setting of the lifting shell 2 can effectively improve the unloading efficiency of the cement from the unloading slope 6. At the same time, after the cement is discharged, the vibration state setting of the hopper 5 and the lifting shell 2 can effectively provide the removal strength and removal efficiency of the residual cement on the hopper 5, thereby reducing the residual rate of cement on the hopper 5, and maintaining the single lifting capacity of the hopper 5, thereby improving the lifting efficiency of the cement by the lifting equipment and reducing the interference load when the lifting equipment is working;

[0043] The transmission component includes a tensioning frame 22 slidably connected to the carrier 1, a tensioning spring 41 limited by the carrier 1 is installed on the side of the tensioning frame 22, a tensioning shaft 23 is rotatably connected to the tensioning frame 22, and two second belts are connected to the tensioning shaft 23 in a transmission manner. Two driving rollers 24 are rotatably installed on the inner wall of the lifting shell 2, and the two driving rollers 24 are both connected in a transmission manner to the annular lifting belt 3, and the wheel shaft 17 and a driving roller 24 are both connected in a transmission manner to the two second belts;

[0044] When the power motor 18 outputs the rotation speed, the driving roller 24 rotates at the set speed. After the driving roller 24 rotates, it drives the annular lifting belt 3 to move. After the annular lifting belt 3 moves, it drives the lifting component to change its position, thereby performing the cement lifting operation.

[0045] The transmission component also includes a pulley 25 rotatably mounted on the two driving rollers 24, the two pulleys 25 are both rotatably connected to the lifting shell 2, an outer shaft 26 is rotatably mounted on the lifting shell 2, an outer bevel gear is mounted on the outer shaft 26, a first bevel gear is mounted on each of the pulleys 25 and the driving roller 24, the two first bevel gears are both transmission-connected to the outer bevel gear, and the outer bevel gear is arranged between the two first bevel gears;

[0046] When the driving roller 24 rotates, the outer rotating shaft 26 is set so that each pulley 25 rotates coaxially and in the opposite direction with the driving roller 24 at the corresponding position. The coaxial opposite movement of the pulley 25 and the driving roller 24 at the corresponding position causes the annular lifting belt 3 and the annular toothed belt 4 to rotate coaxially and in the opposite direction. The annular lifting belt 3 and the annular toothed belt 4 rotate coaxially and in the opposite direction, so that the annular toothed belt 4 can effectively drive the lifting component during the process of changing its position.

[0047] A group of regularly distributed lifting components are installed on the annular lifting belt 3;

[0048] The lifting component includes a hopper 5 which is clamped with the annular lifting belt 3;

[0049] A clamping strip is fixedly provided on the hopper 5, and a clamping slot for fitting the clamping strip is fixedly provided on the annular lifting belt 3. The cooperation between the clamping strip and the clamping slot facilitates the rapid installation and removal of the lifting components on the annular lifting belt 3.

[0050] A material discharge slope 6 is fixedly provided at the bottom of the hopper 5, and a reciprocating drive member is installed on the hopper 5. The reciprocating drive member is transmission-connected to two symmetrically arranged scrapers 7 with adjustable reciprocating spacing;

[0051] A horizontal stirring pipe 8 is rotatably mounted on the inner wall of the hopper 5, and a plurality of groups of vertical stirring rods 9 are rotatably mounted on the horizontal stirring pipe 8, and a group of stirring blades 10 are mounted on the vertical stirring rods 9;

[0052] A core shaft 11 is rotatably mounted on the inner wall of the horizontal stirring tube 8, and the core shaft 11 and the horizontal stirring tube 8 are driven by the ring toothed belt 4;

[0053] A driven gear 27 is installed on the core shaft 11, and the driven gear 27 is connected to the ring toothed belt 4. An inner rotating shaft 28 is rotatably installed on the hopper 5, and an inner bevel gear 12 is installed on the inner rotating shaft 28. A second bevel gear is installed on the horizontal stirring tube 8 and the core shaft 11, and the two second bevel gears are connected to the inner bevel gear 12. The two second bevel gears are respectively arranged on both sides of the inner bevel gear 12;

[0054] By setting the inner rotating shaft 28, the core shaft 11 and the horizontal stirring tube 8 are in a coaxial and counter-rotating state;

[0055] The coaxial reverse rotation of the core shaft 11 and the horizontal stirring tube 8 occurs, so that the horizontal stirring tube 8 and the vertical stirring rod 9 can finally rotate at a set speed during the revolution. The revolution and rotation of the vertical stirring rod 9 can effectively improve the dispersion and clarity of the cement in the hopper 5, thereby reducing the agglomeration and coagulation rate of the cement during the lifting process. The reduction of the cement agglomeration and coagulation rate can reduce the cement residue and adhesion rate in the hopper 5. On the other hand, the heat in the semi-processed cement clinker can be fully and quickly dissipated, thereby facilitating the subsequent processing of the cement clinker.

[0056] An inner bevel gear 12 is installed on the core shaft 11 and corresponds to the position of each group of vertical stirring rods 9. A linkage bevel gear is installed at the tail end of each vertical stirring rod 9. Each linkage bevel gear is transmission-connected to an inner bevel gear 12 at the corresponding position.

[0057] An air cleaning component is arranged on the inner side of the horizontal stirring pipe 8, and a directional air supply component connected with the air cleaning component is arranged on the lifting shell 2.

[0058] The reciprocating drive member includes a reciprocating screw rod 29 rotatably connected to the hopper 5, and the reciprocating screw rod 29 is respectively provided with a positive thread segment and a negative thread segment, and the positive thread segment and the negative thread segment are respectively connected to the two scrapers 7 in a transmission manner, and two torsion springs 30 are fixedly provided at the rotation connection between the reciprocating screw rod 29 and the hopper 5, and a small gear 31 is installed on the reciprocating screw rod 29, and a half face gear 32 is installed on the horizontal stirring tube 8, and the half face gear 32 is connected to the small gear 31 in a transmission manner, and the radius of the half face gear 32 is 10 times the radius of the small gear 31;

[0059] When the horizontal stirring tube 8 rotates, it drives the half-face gear 32 to rotate. After the half-face gear 32 rotates, the meshing connection setting between the half-face gear 32 and the pinion 31 and the torsion spring 30 setting on the reciprocating screw 29 enable the reciprocating screw 29 to reciprocate forward and reverse within a set period. By achieving the reciprocating forward and reverse effect of the reciprocating screw 29 within the set period, the two scrapers 7 can reciprocate synchronously to approach or reciprocate synchronously to move away. By the reciprocating approach and separation of the two scrapers 7, the cement adhered to the inner wall of the hopper 5 can be scraped off. By achieving the reciprocating scraping effect of cement, the self-cleaning operation of the cement in the hopper 5 during the cement lifting process can be achieved.

[0060] The directional air supply component includes an air cleaning pump 33 installed on the carrier 1, an annular soft plate 34 rotatably installed on the inner wall of the lifting shell 2, and an air cleaning pipe 35 is installed on the lifting shell 2 and adjacent to the discharge nozzle 15. The air outlet port of the air cleaning pump 33 is connected to the air cleaning pipe 35 through a corrugated hose, and the air inlet port of the air cleaning pump 33 is provided with a filter.

[0061] When the power motor 18 is working, the air cleaning pump 33 works periodically. When the material lifting component moves to the corresponding area of ​​the air cleaning pipe 35, the high-pressure airflow in the air cleaning pipe 35 enters the material lifting component and performs air cleaning on the material lifting component after the cement unloading is completed. Through air cleaning, the internal cleanliness of the material lifting component is maintained;

[0062] The air cleaning component includes an external air duct 36 opened in the horizontal stirring pipe 8 and an internal air duct 37 opened in the core shaft 11. The internal air duct 37 is rotationally connected to the external air duct 36. The internal air duct 37 is connected to the annular soft plate 34. A plurality of groups of high-pressure nozzles 38 are installed on the horizontal stirring pipe 8, and each high-pressure nozzle 38 is connected to the external air duct 36.

[0063] When the material lifting component moves to the area corresponding to the air cleaning pipe 35, the high-pressure nozzle 38 discharges high-pressure gas, thereby achieving high-pressure blowing off of the cement adhered to the inside of the hopper 5;

[0064] It also includes a negative pressure suction hood 39 arranged on one side of the discharge nozzle 15 and connected to the lifting shell 2. A negative pressure vacuum cleaner 40 is installed on the carrier 1, and the suction end of the negative pressure vacuum cleaner 40 is connected to the negative pressure suction hood 39 through a hose.

[0065] By providing the negative pressure vacuum cleaner 40, the self-dust suction of the material lifting component and the negative pressure suction removal of the residual cement after the unloading are achieved.

[0066] The working principle of the present invention is: during cement lifting operation, the power motor 18 outputs the speed at a set power. After the power motor 18 outputs the speed, the two cams 19, the two passive wheels 20 and the two elastic tensile members 21 are set, so that the lifting shell 2 can reciprocate within the set stroke. Through the vibration state of the lifting shell 2, on the one hand, the cement can be evenly vibrated in the hopper 5 under the lifting state, and then the load uniformity of the hopper 5 to be lifted cement is improved. By improving the load uniformity, the service life of the lifting device is effectively improved. On the other hand, when cement is in the unloading state, the vibration state setting of the lifting shell 2 can effectively improve the unloading efficiency of cement from the unloading slope 6. At the same time, after the cement is discharged, the vibration state setting of the hopper 5 and the lifting shell 2 can effectively provide the removal strength and removal efficiency of the residual cement on the hopper 5, thereby reducing the residual rate of cement on the hopper 5 and maintaining the single lifting capacity of the hopper 5, thereby improving the lifting efficiency of the cement by the lifting equipment and reducing the interference load when the lifting equipment is working. After the power motor 18 outputs the speed, the driving roller 24 is driven at the set speed. The driving roller 24 rotates, and then drives the annular lifting belt 3 to move. After the annular lifting belt 3 moves, it drives the lifting component to change its position, so as to lift the cement. When the horizontal stirring tube 8 rotates, it drives the half-face gear 32 to rotate. After the half-face gear 32 rotates, the meshing connection between the half-face gear 32 and the pinion 31 and the torsion spring 30 on the reciprocating screw rod 29 enable the reciprocating screw rod 29 to reciprocate forward and reverse within a set period. By realizing the reciprocating forward and reverse effect of the reciprocating screw rod 29 within a set period, it can make The two scrapers 7 can reciprocate and synchronously approach or reciprocate and synchronously move away. The cement adhered to the inner wall of the hopper 5 can be scraped off by the reciprocating approach and separation of the two scrapers 7. The self-cleaning operation of the cement in the hopper 5 during the lifting process of cement can be achieved by realizing the reciprocating scraping effect of cement. When the power motor 18 is working, the air cleaning pump 33 works periodically. When the lifting component moves to the corresponding area of ​​the air cleaning pipe 35, the high-pressure airflow in the air cleaning pipe 35 enters the lifting component and performs air cleaning on the lifting component after the cement unloading is completed. The internal cleanliness of the lifting component is maintained by air cleaning.
