Description

Technical Field

[0001] The utility model relates to the technical field of dry mortar mixing, in particular to a single-shaft dry mortar mixer with double seals to prevent dust leakage. Background Technique

[0002] A dry powder mixer is a mechanical device that uses mechanical force or gravity to evenly mix multiple powder materials, increasing the contact surface area of the materials to promote chemical reactions and accelerating physical changes. It is widely used in the mixing of putty paste, real stone paint, dry powder, putty, medicine, food, chemicals, feed, ceramics, refractory materials, etc., that is, the mixing of powders, powders and glue slurries, and the solid-solid (i.e., powder and powder), solid-slurry (i.e., powder and glue slurry) material mixing in industries such as chemical industry, compound fertilizer, dye, pigment, rubber, building materials, refractory materials, rare earth, plastic glass, new materials, nuclear energy materials, etc. The existing dry powder mixers have poor structural sealing, which is prone to dust leakage, and the mixing effect is not good. It takes a long time to run during production to fully mix the materials, which not only affects the construction environment but also the production efficiency.

[0003] For example, a dry mortar mixer disclosed in the authorized publication number CN220409194U includes a support plate, a lifting rod and a top plate. The lifting rod is movably connected to the top of the support plate, and the top plate is movably connected to the top of the lifting rod. A connecting component is installed on the outer wall of the support plate, and an adjusting component is installed on the outer wall of the top plate. The adjusting component consists of a lifting unit and a limiting unit. The lifting unit is located on the top of the top plate, and the limiting unit is located on the top of the top plate. The connecting component includes a limiting ring, a mixing barrel, a clamping block and a clamping plate. In this dry mortar mixer, by setting the limiting ring, mixing barrel and clamping block, by moving the mixing barrel, the mixing barrel is moved into the interior of the limiting ring. At this time, the clamping block will be clamped with the clamping groove on the outer wall of the mixing barrel, and the limiting and fixing of the mixing barrel is completed at this time. The operation is simple and convenient, avoiding the situation that the mixing barrel shakes during the mixing process, resulting in uneven mixing. However, this utility model lacks sealing measures during the mixing operation, which is prone to dust leakage, not only causing waste but also affecting the quality of the construction environment. Therefore, we have proposed a single-shaft dry mortar mixer with double seals to prevent dust leakage, which solves the sealing problem of this utility model and improves the practical effect of this utility model and the working environment quality of the operators. Content of the Utility Model

[0004] The purpose of the utility model is to provide a single-shaft dry mortar mixer with double seals to prevent dust leakage, so as to solve the problems raised in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A double-sealed dust-leakage-proof dry mortar single-shaft mixer, comprising a stirring mechanism, a cleaning mechanism and a mixing operation cylinder. The cleaning mechanism is located outside the stirring mechanism. A controller and a liquid level window are installed outside the mixing operation cylinder. The stirring mechanism includes a feed inlet, a sealing cover, a convenient pull ring, a water inlet, a solenoid valve, a discharge outlet, a discharge valve, a driving motor, a main stirring shaft, a fixed rod, a cross-shaped stirring blade, a limiting frame, an auxiliary stirring shaft and a spiral stirring blade. The feed inlet is arranged at the top of the mixing operation cylinder. A sealing cover is installed on the top of the feed inlet. A convenient pull ring is arranged at the top of the sealing cover. The water inlet is arranged at the top of the mixing operation cylinder. A solenoid valve is installed at the water inlet. The discharge outlet is arranged at the bottom of the mixing operation cylinder. A discharge valve is installed at the discharge outlet. The driving motor is fixedly installed at the top of the mixing operation cylinder.

[0007] Preferably, the top end of the main stirring shaft is connected to the output end of the driving motor and is rotatably connected to the inner top end of the mixing operation cylinder, and its bottom end is rotatably connected to the limiting frame.

[0008] Preferably, the fixed rod is fixedly installed on the outside of the main stirring shaft. The cross-shaped stirring blades are fixedly installed at both ends of the fixed rod. The limiting frame is fixedly installed on the inner wall of the mixing operation cylinder.

[0009] Preferably, the top end of the auxiliary stirring shaft is fixedly connected to the bottom end of the main stirring shaft, and a spiral stirring blade is fixedly arranged on the outside of the auxiliary stirring shaft.

[0010] Preferably, the cleaning mechanism includes a fixed sleeve, a U-shaped rotating rod and a scraping plate. The fixed sleeve is fixedly installed on the outside of the main stirring shaft. The U-shaped rotating rod is fixedly installed on both sides of the fixed sleeve.

[0011] Preferably, a scraping plate is arranged on one side of the U-shaped rotating rod, and one side of the scraping plate contacts the inner wall of the mixing operation cylinder.

[0012] Preferably, the controller is electrically connected to the driving motor and the solenoid valve.

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] The double-sealed dust-leakage-proof dry-mixed mortar single-shaft mixer opens the sealing cover through a convenient pull ring, injects the powder material into the interior of the mixing operation cylinder from the feeding port. The installation of the sealing cover can effectively avoid the leakage and flying of dust during the raw material mixing process, with simple and effective operation, improving the quality of the construction environment. The driving motor drives the main stirring shaft to rotate, thereby driving the cross-shaped stirring blades to rotate synchronously, and then driving the auxiliary stirring shaft and the spiral stirring blades to rotate synchronously, achieving the mixing and stirring effect of the raw materials. Among them, the spiral stirring blades are located at the conical part at the bottom of the mixing operation cylinder, and their spiral design can generate an upward acting force, thereby avoiding the deposition of the bottom raw materials and affecting the overall mixing uniformity, improving the processing quality of the mixer. The double-sealed dust-leakage-proof dry-mixed mortar single-shaft mixer, through the fixed sleeve, U-shaped rotating rod and scraper set in the cleaning mechanism, when the main stirring shaft is operating, can drive the U-shaped rotating rod synchronously, thereby realizing the effect that the scraper moves along the inner wall of the mixing operation cylinder to scrape off the remaining materials adhered to the inner wall of the mixing operation cylinder. This not only reduces the waste of the mixed material and the inconvenience of manual cleaning, but also avoids the influence on the proportion of subsequent mixing operations, improving the economic benefits of the mixer.

The cleaning mechanism is located outside the stirring mechanism. A controller 301 and a liquid level window 302 are installed outside the mixing operation cylinder 300. The stirring mechanism includes a feed inlet 100, a sealing cover 101, a convenient pull ring 102, a water inlet 103, a solenoid valve 104, a discharge outlet 105, a discharge valve 106, a driving motor 107, a main stirring shaft 108, a fixed rod 109, a cross-type stirring blade 110, a limiting frame 111, an auxiliary stirring shaft 112, and a spiral stirring blade 113. The feed inlet 100 is arranged at the top of the mixing operation cylinder 300. A sealing cover 101 is installed at the top of the feed inlet 100. A convenient pull ring 102 is arranged at the top of the sealing cover 101. The water inlet 103 is arranged at the top of the mixing operation cylinder 300. A solenoid valve 104 is installed at the water inlet 103. The discharge outlet 105 is arranged at the bottom of the mixing operation cylinder 300. A discharge valve 106 is installed at the discharge outlet 105. The driving motor 107 is fixedly installed at the top of the mixing operation cylinder 300.
