Description

Technical Field

[0001] This utility model relates to the field of cement processing equipment technology, specifically to a homogenization device for multi-point feeding of finished cement silos. Background Technology

[0002] Chinese utility model patent CN217670193U discloses a cement batching device for a cement production line. The device includes a support frame with batching boxes evenly embedded in its base. Each batching box has a batching pipe at its bottom, and a solenoid valve is installed on the outer wall of each pipe. Support plates are symmetrically arranged on the lower left and right sides of the support frame's interior. A conveying assembly is positioned between the support plates, and a mixing assembly is located on the lower right side of the conveying assembly. The mixing assembly stirs the batching materials, ensuring uniform mixing. Furthermore, the device includes spray pipes and spray holes. After use, the interior of the mixing box can be rinsed through these pipes and holes, preventing thick layers of cement from adhering to the inner wall and facilitating future use.

[0003] However, in the actual operation of finished cement silos, the aforementioned batching device, as a key pretreatment equipment before cement enters the silo, directly affects the homogenization effect of the cement after it enters the silo due to the stable operation of its mixing components. Specifically, the spray holes of this device are directly exposed inside the mixing tank. During the mixing process of the cement raw materials, cement raw materials can easily enter the spray holes, which can not only cause blockage of the spray holes and affect the subsequent rinsing effect, but may also damage the device due to the solidification of the raw materials in the spray holes, increasing maintenance costs.

[0004] Therefore, in view of the problem that the spray holes in the existing cement batching equipment are easily blocked by cement raw materials, there is an urgent need to develop a homogenization device that can effectively prevent raw materials from entering the spray holes and ensure stable and reliable flushing function for multi-point feeding of finished cement silos. Utility Model Content

[0005] The purpose of this utility model is to provide a homogenization device for multi-point feeding of finished cement silos, which solves the problem in existing cement batching devices where the spray holes in the mixing tank are directly exposed to the mixing environment, making them prone to blockage by cement raw materials and affecting the rinsing effect.

[0006] This utility model provides the following technical solution: a homogenization device for multi-point feeding of finished cement silos, including a support frame, a batching box installed on the support frame, a conveying assembly below the batching box, and a mixing assembly connected to the conveying assembly through a discharge pipe;

[0007] The mixing assembly includes a mixing tank, a mixing rod rotatably mounted on the upper side inside the mixing tank, a connecting pipe at the bottom of the mixing rod, a spray pipe at the end of the connecting pipe, spray holes evenly distributed on the outer wall of the spray pipe, a first water inlet pipe rotatably mounted at the bottom of the connecting pipe, a rotating motor mounted on the top of the mixing tank corresponding to the mixing rod, a second water inlet pipe mounted on the left side of the top surface of the mixing tank, and a discharge pipe mounted at the bottom of the mixing tank.

[0008] The spray pipe is fitted with a slidable shielding sleeve at its upper end. The shielding sleeve has a through hole corresponding to the position of the spray hole. The upper end of the shielding sleeve is provided with a connecting ring. The inner wall of the mixing tank is provided with a driving component. The driving component is used to drive the connecting ring to move in the up and down direction so as to separate or overlap the through hole and the spray hole.

[0009] Compared with the prior art, the beneficial effects of this utility model are: by setting a sliding shielding sleeve to cooperate with the driving component, the through hole of the shielding sleeve is separated from the spray hole of the spray pipe during the stirring process, thereby achieving a sealed shielding of the spray hole. This fundamentally prevents cement raw materials from entering the spray hole and causing blockage or solidification, ensuring that the spray hole can spray water normally during subsequent rinsing, maintaining the reliability of the rinsing function, and reducing the risk of device damage and maintenance costs caused by blockage.

[0015] 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.

[0016] Please see Figure 1-5 This utility model discloses a homogenization device for multi-point feeding of finished cement silos, including a support frame 2, on which multiple batching boxes 1 are installed. The batching boxes 1 are used to hold different cement raw materials. A conveying component 4 is provided below the batching boxes 1. The conveying component 4 is connected to a mixing component through a discharge pipe 8. The conveying component 4 is used to convey the cement raw materials in the batching boxes 1, so that the cement raw materials are conveyed through the discharge pipe 8 to the mixing component for mixing and mixing, thereby realizing the homogenization pretreatment of multi-point feeding.

[0017] Specifically, the mixing assembly includes a mixing tank 10, with the lower end of the feeding pipe 8 connected to the upper end of the mixing tank 10. A mixing rod 72 is rotatably mounted on the upper side inside the mixing tank 10, and a connecting pipe 13 is fixedly mounted on the bottom of the mixing rod 72. A spray pipe 5 is mounted on the end of the connecting pipe 13, and spray holes are evenly opened on the outer wall of the spray pipe 5. A first water inlet pipe 6 is rotatably mounted on the bottom of the connecting pipe 13. A rotating motor 71 is mounted on the top of the mixing tank 10 and corresponding to the mixing rod 72. A second water inlet pipe 3 is mounted on the left side of the top surface of the mixing tank 10 for replenishing water into the mixing tank 10 and adjusting the moisture content of the cement raw materials. A discharge pipe is mounted on the bottom of the mixing tank 10. After the cement raw materials are added to the mixing tank 10, the external power supply of the rotating motor 71 is turned on. The output shaft of the rotating motor 71 drives the mixing rod 72 to rotate. When the mixing rod 72 rotates, it drives the connecting pipe 13 and the spray pipe 5 to rotate together to mix the cement raw materials. After the mixing is completed, the cement is discharged through the discharge pipe, and then water is delivered into the spray pipe 5 through the first water inlet pipe 6 to clean the inner wall of the mixing tank 10 through the spray hole.

[0018] The above is the prior art. For specific structure and principle, please refer to the cement batching device for a cement production line disclosed in Chinese Utility Model Patent No. CN217670193U. It will not be described in detail here. In order to prevent the spray holes from being blocked, the main improvement of this utility model on the basis of the prior art is as follows:

[0019] The spray pipe 5 is fitted with a shielding sleeve 9 that can slide relative to it. The shielding sleeve 9 and the spray pipe 5 are in clearance fit with a clearance of ≤0.5mm. The shielding sleeve 9 has a through hole corresponding to the position of the spray hole. The upper end of the shielding sleeve 9 is provided with a connecting ring 12. The diameter of the connecting ring 12 is consistent with the inner diameter of the mixing box 10. When the stirring rod 72 rotates, the side of the connecting ring 12 slides in contact with the inner wall of the mixing box 10. The inner wall of the mixing box 10 is provided with a driving component 11. The driving component 11 is used to drive the connecting ring 12 to move in the up and down direction to realize the separation or overlap of the through hole and the spray hole.

[0020] By setting up the above structure:

[0021] 1. When mixing cement raw materials, the drive component 11 drives the connecting ring 12 to move, causing the shielding sleeve 9 to move on the spray pipe 5, separating the through hole from the spray hole. In this way, when the rotating motor 71 drives the mixing rod 72 to rotate, the spray pipe 5 drives the shielding sleeve 9 to rotate together. However, since the through hole is separated from the spray hole, the spray hole is blocked, preventing cement raw materials from entering the spray pipe 5 and avoiding clogging of the spray hole.

[0022] 2. When cleaning the mixing tank 10, the driving component 11 drives the connecting ring 12 to move, so that the shielding sleeve 9 moves on the spray pipe 5, so that the through hole coincides with the spray hole. In this way, when cleaning the inner wall of the mixing tank 10, the spray hole can be exposed normally, which solves the problem of easy clogging caused by the spray hole being directly exposed in the cement raw material in the prior art.

[0023] The following is a specific embodiment of the drive component 11.

[0024] like Figure 2 and Figure 3 As shown, the drive component 11 includes two sets of telescopic cylinders 11 fixed on the mixing tank 10. Specifically, they can be small cylinders from the SMC CDJ2B series. The two sets of telescopic cylinders 11 are respectively located at the upper and lower positions of the connecting ring 12, and the telescopic ends of the two sets of telescopic cylinders 11 are respectively in contact with the upper and lower surfaces of the connecting ring 12.

[0025] With the above structure, the two sets of telescopic cylinders 11 can work together to drive the connecting ring 12 to move in the vertical direction. For example, when the connecting ring 12 needs to move upward, the telescopic cylinder 11 in the upper position can be shortened and the telescopic cylinder 11 in the lower position can be extended. It should be noted that the telescopic cylinder 11 only plays the role of support and limit, and is movably connected to the surface of the connecting ring 12.

[0026] The telescopic end of the telescopic cylinder 11 is connected to a wear-resistant structure 15, which slides in contact with the surface of the connecting ring 12.

[0027] In some embodiments, such as Figure 4 As shown, the wear-resistant structure 15 is a rubber block; in some embodiments, such as... Figure 5 As shown, the wear-resistant structure 15 is a pulley. The purpose of the wear-resistant structure 15 is to prevent the telescopic cylinder 11 from directly contacting the connecting ring 12 and to avoid unnecessary wear.

[0028] like Figure 2 As shown, the first water inlet pipe 6 is fixed with an existing rotary joint 14, and the connecting pipe 13 is connected to the first water inlet pipe 6 through the rotary joint 14. The rotary joint 14 is common in the field of pipe connection and will not be described in detail here.

[0029] In some embodiments, such as Figure 2 and Figure 3 As shown, a rubber baffle 16 is fixed to the upper surface of the connecting ring 12. The rubber baffle 16 prevents cement raw materials from entering the surface of the connecting ring 12. Specifically, one end of the rubber baffle 16 is fixedly connected to the surface of the connecting ring 12, and the other end of the rubber baffle 16 slides in contact with the inner wall of the mixing tank 10. In other embodiments, the rubber baffle 16 can also be fixed to the bottom surface of the connecting ring 12 to prevent cement raw materials from contacting the bottom surface of the connecting ring 12. The connection method is similar to that of the rubber baffle 16 on the upper surface of the connecting ring 12, and will not be described in detail here.

[0030] This utility model discloses a homogenization device for multi-point feeding of finished cement silos. By setting a sliding shielding sleeve 9 in cooperation with a driving component 11, the through hole of the shielding sleeve 9 is separated from the spray hole of the spray pipe 5 when the cement raw materials are being mixed, thereby effectively shielding the spray hole and preventing the cement raw materials from entering the spray hole and causing blockage. When it is necessary to clean the mixing tank 10, the driving component 11 drives the shielding sleeve 9 to move so that the through hole coincides with the spray hole, ensuring that the spray hole can spray water normally to achieve the rinsing function.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0032] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
