Description

Technical Field

[0001] This utility model relates to the field of mixing mechanism technology, specifically a lime mixing mechanism with a flow limiting mechanism. Background Technology

[0002] Lime is an air-hardening inorganic cementing material with calcium oxide as its main component. It is produced by calcining limestone, dolomite, chalk, seashells, and other products with high calcium carbonate content at 900–1100℃. A stirring mechanism is required during the mixing of lime slurry with liquids.

[0003] For example, utility model CN216538200U discloses a high-efficiency lime mixing tank with a U-shaped stirring mechanism. This solves the problem that in existing technologies, lime mixing usually requires personnel to supervise it and remove the mixed lime within a specified time. Furthermore, if the lime is not removed promptly after mixing, it can easily solidify within a short period, causing inconvenience. The high-efficiency lime mixing tank with a U-shaped stirring mechanism includes an outer shell. A drive motor is mounted on the top of the outer shell, and supports are fixedly connected to both sides of the drive motor. The end of the support away from the drive motor is fixedly connected to one side of the top of the outer shell.

[0004] The aforementioned patented technology proposes a high-efficiency lime mixing tank with a U-shaped stirring mechanism, which optimizes the traditional method of manually driving a stirring rod to prevent lime from solidifying. It reduces energy consumption and lowers production costs by using a low-power motor. However, in the actual mixing process of lime slurry and liquid, the lime slurry and liquid need to be added to the mixing tank all at once for concentrated mixing. This method easily leads to lumps of lime slurry and liquid during actual mixing, severely affecting the efficiency and thoroughness of the mixing. In other words, the aforementioned patented technology has the drawback of not being able to automatically add lime slurry gradually into the mixing tank for mixing.

[0005] Therefore, a lime mixing mechanism with a flow-limiting mechanism is proposed to solve the above-mentioned problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] To address the shortcomings of existing technologies, this utility model provides a lime stirring mechanism with a flow-limiting mechanism, which has the advantage of being able to gradually mix lime slurry and liquid, thus solving the defect in existing technologies that cannot automatically add lime slurry gradually into the stirring tank for mixing.

[0008] (II) Technical Solution

[0009] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A lime mixing mechanism with a flow limiting mechanism includes a mixing tank. A lime slurry storage tank is fixed on the upper surface of the mixing tank by a mounting rod, and a liquid storage tank is also fixed on the upper surface of the mixing tank. A liquid pump for conveying the liquid in the liquid storage tank into the mixing tank is provided on the lower surface of the liquid storage tank. A feeding pipe and a discharging pipe are respectively provided at the bottom end of the lime slurry storage tank and the bottom end of the mixing tank. A material conveying and mixing component extending into the mixing tank is provided inside the lime slurry storage tank.

[0010] The material conveying and mixing assembly includes a rotating rod rotatably mounted on the top wall inside the lime slurry storage tank. The bottom end of the rotating rod penetrates the interior of the feeding pipe and extends through the mixing tank to the interior of the discharge pipe. The surface of the rotating rod is respectively provided with a first spiral conveying blade and a second spiral conveying blade, and the spiral directions of the first spiral conveying blade and the second spiral conveying blade are opposite. The first spiral conveying blade and the second spiral conveying blade are rotatably connected to the inner walls of the feeding pipe and the discharge pipe, respectively. The outer surface of the rotating rod is also provided with a mixing assembly, and the upper surface of the lime slurry storage tank is provided with a drive motor for driving the rotating rod to rotate.

[0011] The beneficial effects of this utility model are as follows: By setting up a clinker stirring component, this utility model can achieve the purpose of automatic and uniform feeding. At the same time, under the action of the infusion pump, the liquid in the storage tank can be sprayed onto the surface of the fallen lime slurry through several atomizing nozzles, which improves the thoroughness of mixing and can gradually mix the lime slurry and the liquid. This avoids the method of directly mixing the whole lime slurry and liquid in the prior art, effectively improving the mixing efficiency. Thus, it effectively solves the defect of the prior art that cannot automatically add lime slurry to the stirring tank for mixing.

[0012] This lime mixing mechanism with a flow-limiting device has the advantage of being able to gradually mix lime slurry and liquid.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the stirring assembly includes several stirring blades fixed on the surface of the rotating rod, and the several stirring blades are divided into two groups, with the two groups of stirring blades symmetrically arranged on the surface of the rotating rod.

[0015] The advantage of adopting the above-mentioned further scheme is that the setting of two sets of stirring blades facilitates the thorough stirring of lime slurry and liquid in the mixing tank.

[0016] Furthermore, two symmetrical mounting posts are fixedly provided on the surface of the rotating rod, and the ends of the two mounting posts are each fixedly provided with scrapers that are slidably connected to the inner wall of the mixing tank.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the scraper makes it easier to scrape off the lime slurry and liquid adhering to the inner wall of the mixing tank, thereby improving the thoroughness of mixing.

[0018] Furthermore, the upper surfaces of the lime slurry storage tank and the liquid storage tank are both equipped with filling pipes, and the surface of the discharge pipe is equipped with a discharge valve.

[0019] The advantage of adopting the above-mentioned further scheme is that it facilitates the addition of lime slurry and liquid.

[0020] Furthermore, the inner top wall of the mixing tank is fixed with an annular pipe by a mounting bracket, the inlet end of the infusion pump extends into the interior of the storage tank, and the outlet end of the infusion pump is provided with an infusion pipe that communicates with the annular pipe.

[0021] The advantage of adopting the above-mentioned further solution is that it facilitates the transfer of liquid from the storage tank into the interior of the mixing tank.

[0022] Furthermore, the outer surface of the annular pipe is circumferentially arrayed with several atomizing nozzles that communicate with the annular pipe.

[0023] The advantage of adopting the above-mentioned further solution is that the setting of the atomizing nozzle makes it easier to spray the liquid evenly on the surface of the lime slurry in the mixing tank. Attached Figure Description

[0029] 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.

[0030] In the embodiments, by Figure 1-4 The present invention provides a lime mixing mechanism with a flow limiting mechanism. The present invention includes a mixing tank 1, a lime slurry storage tank 2 fixedly mounted on the upper surface of the mixing tank 1 by means of a mounting rod, and a liquid storage tank 3 fixedly mounted on the upper surface of the mixing tank 1. Both the lime slurry storage tank 2 and the liquid storage tank 3 are fitted with filling pipes on their upper surfaces, and a discharge valve is provided on the surface of the discharge pipe 6.

[0031] The lower surface of the storage tank 3 is provided with a liquid pump 4 for conveying the liquid in the storage tank 3 into the mixing tank 1. The inner top wall of the mixing tank 1 is fixed with an annular pipe 8 by a mounting bracket. The inlet end of the liquid pump 4 extends into the interior of the storage tank 3, and the outlet end of the liquid pump 4 is provided with a liquid delivery pipe 9 that communicates with the annular pipe 8.

[0032] The outer surface of the annular pipe 8 is circumferentially arrayed with several atomizing nozzles 10 that communicate with the annular pipe 8.

[0033] The bottom of the lime slurry storage tank 2 and the bottom of the mixing tank 1 are respectively provided with a feeding pipe 5 and a discharge pipe 6, and the interior of the lime slurry storage tank 2 is provided with a material conveying and mixing component 7 extending into the interior of the mixing tank 1.

[0034] The material conveying and mixing assembly 7 includes a rotating rod 701 rotatably mounted on the top wall inside the lime slurry storage tank 2. The bottom end of the rotating rod 701 passes through the interior of the feeding pipe 5 and extends through the mixing tank 1 to the interior of the discharge pipe 6. The surface of the rotating rod 701 is respectively provided with a first spiral conveying blade 702 and a second spiral conveying blade 703, and the spiral directions of the first spiral conveying blade 702 and the second spiral conveying blade 703 are opposite. The first spiral conveying blade 702 and the second spiral conveying blade 703 are rotatably connected to the inner walls of the feeding pipe 5 and the discharge pipe 6, respectively. The outer surface of the rotating rod 701 is also provided with a mixing assembly, and the upper surface of the lime slurry storage tank 2 is provided with a drive motor 704 for driving the rotating rod 701 to rotate.

[0035] The stirring assembly includes several stirring blades 705 fixed on the surface of the rotating rod 701, and the stirring blades 705 are divided into two groups, with the two groups of stirring blades 705 symmetrically arranged on the surface of the rotating rod 701.

[0036] Two symmetrical mounting posts 706 are also fixed on the surface of the rotating rod 701, and scraper rods 707 that are slidably connected to the inner wall of the mixing tank 1 are fixed at the ends of the two mounting posts 706.

[0037] Working principle:

[0038] During the mixing process of lime slurry, the drive motor 704 can be started to drive the rotating rod 701 to rotate. The rotation of the rotating rod 701 automatically conveys the lime slurry pre-stored in the lime slurry storage tank 2 into the mixing tank 1 through the feed pipe 5 via the first spiral conveyor 702, thereby achieving the purpose of automatic and uniform feeding. At the same time, the feeding speed can be adjusted by adjusting the speed of the drive motor 704, which is highly practical. During the feeding process inside the mixing tank 1, the liquid in the storage tank 3 can be transported into the interior of the annular pipe 8 by the action of the liquid pump 4, and then conveyed through several mists. The spray nozzle 10 sprays onto the surface of the fallen lime slurry, and the rotating rod 701, during its rotation, drives the stirring blade 705 to fully stir the lime slurry and liquid. At the same time, the scraper 707 scrapes off the lime slurry adhering to the inner wall of the mixing tank 1, improving the thoroughness of mixing and gradually mixing the lime slurry and liquid. This avoids the method of directly mixing the entire lime slurry and liquid in the prior art, effectively improving the mixing efficiency and thus effectively solving the defect in the prior art that it cannot automatically add lime slurry to the mixing tank 1 for mixing.

[0039] Simultaneously, after mixing is complete, the discharge valve can be opened, and the motor 704 can be driven to reverse, causing the rotating rod 701 to rotate, thereby driving the second spiral conveyor 703 to reverse, thus facilitating the discharge of the mixed material in the mixing tank 1 and achieving the purpose of automatic material discharge.
