Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, specifically to cement processing mixing equipment with cleaning function. Background Technology

[0002] In the production of cement, in order to improve the performance of cement and adjust the grade of cement, it is necessary to add appropriate cement admixtures to the cement for mixing. Cement admixtures are classified into two categories according to their performance: active (hydraulic) admixtures and inactive (filler) admixtures.

[0003] Patent (CN220593588U) discloses a foamed cement insulation board processing and mixing equipment, including a mixing tank, a support frame, a feeding funnel, and a discharging valve, as well as a stirring assembly. The stirring assembly includes a rotating sleeve, a sleeve shaft, a guide frame, a driving plate, a driving component, a stirring component, and a transmission component. The rotating sleeve is rotatably connected to the mixing tank, the sleeve shaft is slidably connected to the rotating sleeve, the guide frame is fixedly connected to the mixing tank, the driving plate is rotatably connected to the sleeve shaft, the driving component is connected to the mixing tank, the stirring component is connected to the sleeve shaft, and the transmission component is connected to the mixing tank. This allows the raw materials in the tank to be stirred and mixed in different directions through the provided components, resulting in a better overall mixing effect and a better processing effect in actual use.

[0004] The mixing equipment in the aforementioned patent documents cleans the inner wall of the mixing tank using a circular scraper. However, the circular scraper needs to be adjusted up and down, and the sleeve shaft and stirring rod also need to be adjusted up and down synchronously inside the mixing tank. However, the pressure of the cement mixture inside the mixing tank acts on the stirring rod and sleeve shaft, making the resistance of adjusting the circular scraper too high. This resistance is transmitted to the bevel gear and gear, causing the bevel gear and gear to be easily damaged, and affecting the mixing efficiency of the mixing tank. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4This utility model provides a technical solution: a cement processing and mixing equipment with a cleaning function, including a mixing tank 1. A vertically rotatably connected stirring shaft 2 is installed inside the mixing tank 1. A servo motor 6 is located at the center of the top of the mixing tank 1, and the output end of the servo motor 6 is fixedly connected to the top of the stirring shaft 2. A support frame 3 is provided on one side of the outer wall of the stirring shaft 2. A scraper 4 is provided at the end of the support frame 3 away from the stirring shaft 2, and the scraper 4 is in contact with the inner wall of the mixing tank 1. Several first stirring rods 5 are provided on one side of the outer wall of the stirring shaft 2. A first support ball 7 is provided at the end of the outer wall of the first stirring rod 5 away from the stirring shaft 2, and several spiral blades 8 are provided on the outer wall of the first support ball 7. A second stirring rod 201 is provided on the side of the outer wall of the stirring shaft 2 away from the first stirring rods 5, and several second support balls 202 are provided on the outer wall of the second stirring rod 201. A support plate 203 is provided at the bottom of the outer wall of the stirring shaft 2 above the discharge pipe 102, and several fan blades 204 are provided on the outer wall of the support plate 203.

[0024] In one embodiment, a feed inlet 101 is provided on one side of the top of the outer wall of the mixing tank 1, and a discharge pipe 102 is provided at the center of the bottom of the outer wall of the mixing tank 1. A support frame 103 is provided at the bottom of the outer wall of the mixing tank 1 outside the discharge pipe 102. The feed inlet 101 is used to feed cement and cement mixture into the mixing tank 1. The discharge pipe 102 is used to discharge material after the mixing process is completed. A valve is provided on the discharge pipe 102 to ensure that the mixture is discharged directly from the discharge pipe 102 during normal mixing. The support frame 103 is provided to suspend the bottom of the mixing tank 1 to ensure normal discharge from the discharge pipe 102.

[0025] In one embodiment, the spiral blades 8 are radially arranged on the outer wall of the first support ball 7, which limits the distribution position and angle of the spiral blades 8 on the outer wall of the first support ball 7. This allows the spiral blades 8 to stir and mix the mixture inside the mixing tank 1 at different positions and angles on the outside of the first support ball 7, which can effectively improve the stirring and mixing effect of the raw materials inside the mixing tank 1. The first stirring rod 5 is horizontally arranged on the outer wall of the stirring shaft 2, and the distance between two adjacent first support balls 7 is greater than twice the length of the spiral blades 8, which can effectively prevent the spiral blades 8 on the outer walls of different first support balls 7 from colliding.

[0026] In one embodiment, the first support ball 7 is rotatably connected to the first stirring rod 5. When the first stirring rod 5 rotates with the stirring shaft 2 to stir and mix the mixture, the spiral blade 8 is located inside the mixture. As the first stirring rod 5 rotates, the mixture and the spiral blade 8 come into contact and are subjected to mutual compression and force. The force on the spiral blade 8 is transmitted to the first support ball 7, causing the first support ball 7 to rotate along the axial direction of the first stirring rod 5. This allows the spiral blade 8 to rotate along the axial direction of the first stirring rod 5, which can effectively improve the diversity of the contact angle between the spiral blade 8 and the mixture, and further improve the stirring and mixing effect of the mixture inside the mixing tank 1.

[0027] In one embodiment, the outer diameter of the second support ball 202 is greater than twice the outer diameter of the second stirring rod 201, and the outer diameter of the second support ball 202 is less than four times the outer diameter of the second stirring rod 201. The dimensions of the second support ball 202 and the second stirring rod 201 are limited to ensure that when the second support ball 202 rotates with the second stirring rod 201, the second support ball 202 and the second stirring rod 201 can perform different forms of stirring and mixing treatment on the mixture.

[0028] The working principle of this utility model:

[0029] Refer to the instruction manual appendix Figures 1-4 This utility model, by setting up a stirring shaft 2, a support frame 3, a scraper 4, a first stirring rod 5, a first support ball 7, and a spiral blade 8, uses a servo motor 6 to drive the stirring shaft 2 to rotate. The stirring shaft 2 drives the support frame 3 and the first stirring rod 5 to rotate. The support frame 3 drives the scraper 4 to scrape the material along the inner wall of the mixing tank 1, which can effectively clean the mixed material on the inner wall of the mixing tank 1. The scraper 4 can move in a circle along the inner wall of the mixing tank 1 with the rotation of the stirring shaft 2. The cleaning operation of the inner wall of the mixing tank 1 is convenient and quick. The scraper 4 does not need to move up and down, and there is no need to equip it with the up and down adjustment components in the prior art. This can effectively ensure the service life of the equipment, and at the same time, it will not adversely affect the rotation of the stirring shaft 2, thus ensuring the stirring efficiency of the mixing tank 1.

[0030] The first stirring rod 5 rotates along with the stirring shaft 2, stirring and mixing the mixture inside the mixing tank 1. The first support ball 7 moves in a circular motion around the stirring shaft 2 along with the first stirring rod 5, continuously contacting and separating from the mixture, causing the mixture to undergo spherical dispersion and convergence, effectively improving the stirring and mixing effect. The spiral blade 8 is located on the outer wall of the first support ball 7, allowing it to move in a circular motion around the stirring shaft 2 along with the first support ball 7, effectively improving the stirring and mixing effect. The spiral blade 8 moves in a spiral shape around the stirring shaft 2, and the mixture undergoes spiral dispersion through the surface of the spiral blade 8, further improving the stirring and mixing effect inside the mixing tank 1.

[0031] The second stirring rod 201 can rotate with the stirring shaft 2, and the second support ball 202 rotates with the second stirring rod 201, so that the second support ball 202 moves in a circle around the stirring shaft 2. The second stirring rod 201 and the second support ball 202 cooperate with the first stirring rod 5 to further improve the mixing effect of the mixture inside the mixing tank 1.

[0032] The support plate 203 rotates at the bottom of the stirring shaft 2 along with the stirring shaft 2. The support plate 203 rotates above the discharge pipe 102 at the bottom center of the mixing tank 1. The fan blade 204 rotates with the support plate 203. The fan blade 204 rotates and pushes the mixture at the bottom center of the mixing tank 1, making the mixture flow more smoothly during the feeding process and effectively avoiding material blockage.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
