Description

Technical Field

[0001] The utility model relates to the technical field of mixers, in particular to a high-speed mixer for grouting agents. Background Art

[0002] The high-speed grouting agent mixer is mainly used in railways, water conservancy, construction industries, colleges and universities, scientific research institutions, and quality inspection departments as a mixing machine for grouting, mortar, and pure slurry strength tests. It has two relative rotations: the stirring blade moves clockwise and the mixing barrel moves counterclockwise, so it has the characteristics of uniform mixing, short mixing time, high efficiency, and easy operation.

[0003] However, due to the high viscosity of the grouting agent, the grouting agent will adhere to the inner wall of the mixing barrel after use, which not only causes a waste of the grouting agent, but also the grouting agent attached to the inner wall will coagulate into lumps if not cleaned in time. When the mixer is used next time, the grouting agent adhered to the inner wall may fall off the inner wall due to the stirring action of the stirring device, mix with the new grouting agent and flow out of the mixer, resulting in the presence of lumps of grouting agent in the grouting agent after stirring, affecting the effect of the grouting agent.

[0004] In the prior art, a cleaning device is provided in the mixer to clean the mixing barrel. For example, the existing patent CN217016288U discloses a high-speed mixer for grouting agent, which includes a base, a mixing barrel, a transverse screw, a first motor, a movable seat, a rotating plate, a mixing assembly and a cleaning assembly. A vertical screw is rotatably installed on one side of the rotating plate close to the mixing assembly. A third motor for driving the vertical screw to rotate is installed on the upper end of the vertical screw. A lifting seat is threadedly connected to the surface of the vertical screw, and the mixing assembly is installed on one side of the lifting seat. The implementation principle of the present application is: when in use, the first motor can be started to drive the transverse screw to rotate, so that the moving seat can move horizontally along the length direction of the transverse screw, so that the position of the mixing barrel can be adjusted. When stirring, the mixing barrel is moved to the bottom of the stirring assembly, and the third motor is started to drive the vertical screw to rotate, so that the lifting seat can move vertically along the length direction of the vertical screw, so that the stirring assembly is lowered into the mixing barrel for stirring. When cleaning is needed, the mixing barrel can be moved to the bottom of the cleaning assembly, and the cleaning assembly can be used to clean the mixing barrel in time to remove the grouting agent attached to the inner wall of the mixing barrel for easy reuse.

[0005] In the above-mentioned public patent, when the grouting agent is stirred, the mixing barrel is located at the position of the mixing component, and the cleaning component is arranged on the side of the mixing component. When the mixing barrel needs to be cleaned, the mixing component needs to be moved upward and then moved to the side where the cleaning component is located. The operation is cumbersome and the separate setting of the cleaning component makes the overall footprint of the mixer larger. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a high-speed grouting agent mixer, aiming to solve the problem that the existing grouting agent mixer needs to be separately provided with a cleaning component to clean the mixing barrel, resulting in complex overall operation of the mixer and a large footprint.

[0007] In order to solve the above problems, the technical solution adopted by the utility model is: a high-speed mixer for grouting agent, comprising a fixed seat, a mixing barrel, and a first motor electrically connected to a power supply, the mixing barrel is fixedly installed inside the fixed seat, the first motor is fixedly installed on the top of the fixed seat, the output shaft of the first motor is fixedly installed with a mixing shaft, the mixing shaft extends into the inside of the mixing barrel, the middle part of the mixing shaft is hollow, a mixing rod is fixedly installed on the mixing shaft, the inside of the mixing rod is hollow, the mixing rod is connected to the middle part of the mixing shaft, and a through hole is opened at the end of the mixing rod away from the mixing shaft, a one-way valve is fixedly installed in the through hole, a water source channel is opened on the top of the fixed seat, a through groove is opened on the mixing shaft in contact with the water source channel, and a rotating sealing ring is arranged between the mixing shaft and the fixed seat, and a discharge port is arranged on one side of the mixing barrel.

[0008] The principles of this solution are:

[0009] During the stirring process of the extruder, the stirring shaft is driven to rotate by the first motor, and the stirring rod stirs the extrudate in the stirring barrel. After the stirring of the extrudate is completed, it is discharged from the discharge port. When the stirring barrel needs to be cleaned, the stirring shaft and the middle part of the stirring rod are set to a hollow state, and a water source channel is opened on the top of the fixed seat. Water is poured into the stirring shaft through the water source channel, then flows into the stirring rod, and then sprayed out from the one-way valve at the end of the stirring rod to rinse the inner wall of the stirring barrel.

[0010] The beneficial effects of this program are:

[0011] 1. By setting the stirring shaft and stirring rod to a hollow state, when the stirring barrel needs to be cleaned, water is directly poured into the stirring shaft and the stirring barrel and sprayed out through the end of the stirring rod to flush the stirring barrel. The stirring shaft and stirring rod can not only complete the stirring of the extrusion agent, but also realize the cleaning of the inner wall of the stirring barrel;

[0012] 2. A one-way valve is provided at the end of the stirring rod to prevent the extruder from entering the stirring rod from the end of the stirring rod. During the operation of the mixer, the stirring rod rotates in the stirring barrel as the stirring shaft rotates. Therefore, the extrudate in the stirring barrel will not cause blockage to the one-way valve. After the extrudate is stirred, water is immediately poured into the stirring barrel to clean the stirring barrel. This will not cause the extruder to adhere to the end of the stirring rod. Therefore, the normal use of the one-way valve will not be affected.

[0013] Furthermore, a rotating plate is fixedly installed under the mixing barrel, a second motor is fixedly installed on a fixed seat at the bottom of the rotating plate, the top end of the output shaft of the second motor is fixedly connected to the bottom of the rotating plate, and the rotating plate is slidably installed on the fixed seat. The second motor drives the rotating plate to rotate, thereby driving the mixing barrel to rotate, and the mixing barrel also rotates while the mixing shaft and the mixing rod rotate, and the rotation direction is opposite, thereby accelerating the mixing of the extruded agent and the cleaning speed of the mixing barrel.

[0014] Furthermore, a fixing groove matching the mixing barrel is provided on the upper surface of the rotating plate, the fixing groove matches the mixing barrel, and an electromagnet is fixedly installed in the fixing groove, the mixing barrel is made of magnetic material, and the electromagnet is electrically connected to a power source. The mixing barrel is fixed in the fixing groove by energizing the electromagnet, so that the rotating plate can rotate to drive the mixing barrel to rotate, and the mixing barrel can also be removed for maintenance or replacement.

[0015] Furthermore, a plurality of support rods are fixedly installed at the same interval on the inner wall of the fixing seat, and a protective ring is arranged on the outer periphery of the mixing barrel, and the support rods and the protective ring are fixedly connected. The protective ring is fixed to the outer periphery of the mixing barrel through the support rods to protect the mixing barrel, so as to prevent the mixing barrel from being skewed or shifted during the rotation process.

[0016] Furthermore, a stirring blade is fixedly mounted on the outer wall of the stirring rod at one end of the stirring rod away from the stirring shaft. The stirring blade scrapes the inner wall of the stirring barrel during the rotation of the stirring shaft, thereby accelerating the cleaning of the stirring barrel and fully stirring the extrudate during the stirring process.

DETAILED DESCRIPTION

[0019] The following is further described in detail through specific implementation methods:

[0020] like Figure 1As shown, the structure of a high-speed mixer for grouting agent is as follows: it includes a fixed seat 101, a mixing barrel 102 is fixedly arranged inside the fixed seat 101, and a rotating plate 302 is also arranged at the bottom of the mixing barrel 102, a second motor 301 is fixedly installed on the fixed seat 101 at the bottom of the rotating plate 302, the output shaft of the second motor 301 is fixedly connected to the bottom of the rotating plate 302, a fixed groove 303 is opened on the top of the rotating plate 302, the fixed groove 303 matches the mixing barrel 102, and an electromagnet 304 is fixedly installed in the fixed groove 303, the electromagnet 304 is connected to a power supply, the mixing barrel 102 is fixedly installed in the fixed groove 303, and the mixing barrel 102 is made of magnetic material, and a first motor 201 is fixedly installed on the fixed seat 101 above the mixing barrel 102, The output shaft of the first motor 201 is fixedly installed with a stirring shaft 202, and a stirring rod 203 is fixedly installed on the stirring shaft 202. The middle parts of the stirring shaft 202 and the stirring rod 203 are both in a hollow state. A water source channel 103 is also provided on the fixed seat 101 above the stirring barrel 102, and a through groove is provided on the stirring shaft 202 in contact with the water source channel 103, and a rotating sealing ring 104 is fixedly installed at the fixed position between the fixed seat 101 and the stirring shaft 202 to prevent water from being poured into the stirring shaft 202 when water is poured into the stirring shaft 202; a through hole is provided at the end of the stirring rod 203 away from the stirring shaft 202, a one-way valve 204 is fixedly installed in the through hole, and a stirring blade 205 is fixedly installed on the outer wall of the stirring rod 203 at the end of the stirring rod 203 away from the stirring shaft 202.

[0021] A discharge port is provided at one side of the bottom of the mixing barrel 102 to discharge the extrusion agent in the mixing barrel 102 and the mixture of water and the extrusion agent generated by cleaning the mixing barrel 102 out of the mixing barrel 102 .

[0022] A plurality of support rods are installed at the same interval on the inner wall of the fixed seat 101, and the support rods are perpendicular to the mixing barrel 102. A protective ring is arranged on the outer periphery of the mixing barrel 102, and one end of the support rod away from the inner wall of the fixed seat 101 is fixedly connected to the protective ring to fix the protective ring on the outer periphery of the mixing barrel 102.

[0023] Here’s how it works:

[0024] When the mixer is used to mix the extruder, the first motor 201 and the second motor 301 are started to rotate at the same time, and the rotation directions of the first motor 201 and the second motor 301 are opposite, that is, the first motor 201 rotates clockwise and the second motor 301 rotates counterclockwise, or the first motor 201 rotates counterclockwise and the second motor 301 rotates clockwise. When the first motor 201 and the second motor 301 are started, the electromagnet 304 is energized to fix the mixing barrel 102 on the rotating plate 302. When the second motor 301 rotates, the rotating plate 302 and the mixing barrel 102 on the rotating plate 302 are driven to rotate. The rotation of the first motor 201 drives the mixing shaft 202 and the mixing rod 203 to rotate in the mixing barrel 102. When the mixing rod 203 stirs the extruded agent in the mixing barrel 102, the mixing barrel 102 is also rotated driven by the second motor 301, thereby accelerating the stirring of the extruded agent.

[0025] After the extrudate is stirred, it is discharged from the mixing barrel 102 through the discharge port. Then, the mixing barrel 102 needs to be cleaned. Water is poured into the mixing shaft 202 through the water source channel 103. The water in the mixing shaft 202 enters the mixing rod 203 and is then sprayed out through the one-way valve 204. The water sprayed from the end of the mixing rod 203 directly impacts the inner wall of the mixing barrel 102, so that the extrudate attached to the inner wall of the mixing barrel 102 can be washed off. At the same time, the first motor 201 is started to rotate, and the second motor 202 is started to rotate. One rotation drives the stirring shaft 202 and the stirring rod 203 to rotate, and the rotation of the stirring rod 203 drives the stirring blade 205 to rotate. While spraying water on the inner wall of the stirring barrel 102, the stirring blade 205 scrapes the inner wall of the stirring barrel 102 to speed up the cleaning of the inner wall of the stirring barrel 102. It is only necessary to control the working status of the first motor 201, the second motor 301 and the solenoid valve to achieve the stirring of the extruded agent and the cleaning of the stirring barrel 102. The operation is simple and there is no need to set up a separate cleaning structure, and the area occupied is small.

[0026] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
