Description

Technical Field

[0001] This invention belongs to the field of cementitious powder production technology, specifically a high-efficiency cementitious powder mixing and conveying device. Background Technology

[0002] Cementitious powder is a powdered material with functions such as bonding and curing. It is widely used in construction, industry and other fields. Currently, the production of cementitious powder requires mixing raw materials such as cementing materials, fillers and additives.

[0003] In existing technologies, the mixing of cementitious powder raw materials mostly relies on stirring equipment. When existing stirring equipment is working, various raw materials need to be poured into the mixing drum, and then the stirring mechanism is used to stir and mix the cementitious powder raw materials in the mixing drum. After the cementitious powder raw materials are mixed, the cementitious powder raw materials in the mixing drum need to be discharged, and then the raw materials need to be poured back into the mixing drum for the next batch of mixing. It can be seen that the time consumed in the mixing process between adjacent batches of cementitious powder raw materials is relatively long, which is not conducive to improving the production efficiency of cementitious powder.

An annular stop is fixedly disposed on the outside of the slide rod. One end of the second elastic element is connected to the first support, and the other end is connected to the annular stop.

[0015] As a further improvement of the present invention: a central cavity is formed at the center of the mixing roller.

[0016] The stirring assembly includes a stirring shaft, a stirring rod, and a power unit.

[0017] One end of the stirring shaft extends into the interior of the mixing chamber, and the other end extends into the interior of the central chamber. Several sets of stirring rods are provided, and several stirring rods are fixedly mounted on the shaft of the stirring shaft located inside the mixing chamber. The power assembly is located inside the central chamber. When the mixing roller rotates, the power assembly is used to drive the stirring shaft to rotate.

[0018] As a further improvement of the present invention: a plurality of second arc-shaped blocks are also fixedly arranged on the side wall of the upright plate, and the plurality of second arc-shaped blocks are distributed at intervals in an arc-shaped structure.

[0019] The power assembly includes a gear, a rack, and a first elastic element.

When a certain set of mixing chambers is rotated to an upward-facing position, the mixing chamber is located directly below the storage cylinder. The sealing component corresponding to the mixing chamber is moved by the corresponding first drive component, thereby opening the first inlet / outlet corresponding to the mixing chamber.

After the mixing chamber has been fed for a certain period of time, the second drive component drives the mixing roller to rotate again. At this time, the mixing chamber originally located below the storage cylinder rotates away, and then... The mixing chamber rotates to a position below the storage cylinder. After the mixing chamber moves away from the position below the storage cylinder, the first drive component drives the sealing component to move in the opposite direction to close the first inlet and outlet. Then, the stirring component starts to work to stir the cementitious powder raw material. The next mixing chamber rotates to a position below the storage cylinder and continues to be fed. After a certain period of stirring, the cementitious powder raw material in a certain mixing chamber rotates to face downwards. At this time, the first drive component drives the sealing component to move again to reopen the first inlet and outlet. The mixed cementitious powder raw material in the mixing chamber is output from the first inlet and outlet, realizing the automatic unloading of the cementitious powder raw material. Compared with the existing technology, it can realize the automatic feeding, automatic stirring and mixing, and automatic unloading of cementitious powder raw material, thereby shortening the mixing time between two adjacent batches of cementitious powder raw material and improving the mixing efficiency of cementitious powder raw material.

Detailed Implementation

[0032] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0033] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Please see Figure 1-5This embodiment provides a high-efficiency cementitious powder mixing and conveying device, including a base 10, a mixing roller 20, a sealing assembly 30, a storage cylinder 40, a stirring assembly 50, a first drive assembly 60, and a second drive assembly 70. A vertical plate 101 is fixedly mounted on the upper part of the base 10. The mixing roller 20 is disposed on one side of the vertical plate 101. A plurality of annularly spaced mixing chambers 201 are formed at the inner edge of the mixing roller 20. A plurality of first inlet and outlet ports 203 communicating with the mixing chambers 201 are formed on the circumferential sidewall of the mixing roller 20. The storage cylinder 40 is fixedly mounted on one side of the vertical plate 101 and located above the mixing roller 20. A solenoid valve (not shown in the figure) is installed in the outlet pipe at the bottom of the storage cylinder 40. The second drive assembly 70 is installed... Mounted on the side wall of the vertical plate 101, it is used to drive the mixing roller 201 to rotate intermittently. Several sets of sealing components 30 and stirring components 50 are provided one-to-one with the mixing chamber 201. Several sets of sealing components 30 are movably arranged on the circumferential side wall of the mixing roller 20, and several sets of stirring components 50 are correspondingly arranged inside several sets of mixing chambers 201. When the second driving component 70 drives the mixing roller 201 to rotate intermittently, the stirring component 50 is used to stir the cementitious powder raw material inside the mixing chamber 201. Each set of sealing components 30 is provided with a set of first driving components 60 at one end. The first driving component 60 is used to drive the sealing component 30 to move, so as to control the opening and closing of the first inlet and outlet 203.

[0035] When mixing of cementitious powder raw materials is required, several different cementitious powder raw materials can be placed inside the storage cylinder 40. Then, the second drive component 70 drives the mixing roller 20 to rotate intermittently, causing several mixing chambers 201 to rotate sequentially to an upward position. When a set of mixing chambers 201 is rotated to an upward position, the mixing chamber 201 is located directly below the storage cylinder 40. The sealing component 30 corresponding to the mixing chamber 201 is moved by the corresponding first drive component 60, thereby opening the first inlet / outlet 203 corresponding to the mixing chamber 201. Then, the solenoid valve in the discharge pipe at the bottom of the storage cylinder 40 opens, allowing the cementitious powder raw materials to be output through the discharge pipe and then enter the mixing chamber 201 through the opened first inlet / outlet 203, realizing automatic feeding of cementitious powder raw materials. After the mixing chamber 201 has been fed for a certain period of time, the second drive component 70 drives the roller 20 to rotate intermittently. When the mixing roller 20 rotates, the mixing chamber 201 originally located below the storage cylinder 40 rotates away, and the next set of mixing chambers 201 rotates to a position below the storage cylinder 40. After the mixing chambers 201 rotate away from the position below the storage cylinder 40, the first drive component 60 drives the sealing component 30 to move in the opposite direction to close the first inlet / outlet 203. Then, the stirring component 50 starts to work to stir the cementitious powder raw material. The next set of mixing chambers 201 that rotates to the position below the storage cylinder 40 continues to be fed. When the cementitious powder raw material in a certain set of mixing chambers 201 has been stirred for a certain period of time, the set of mixing chambers 201 rotates to face downwards. At this time, the first drive component 60 drives the sealing component 30 to move again to reopen the first inlet / outlet 203. The mixed cementitious powder raw material in the set of mixing chambers 201 is output from the first inlet / outlet 203, realizing the automatic unloading of the cementitious powder raw material.

[0036] Please see Figure 1 as well as Figure 4In one embodiment, two sets of first arc-shaped blocks 102 are fixedly disposed on the side wall of the upright plate 101, and the two sets of first arc-shaped blocks 102 are distributed vertically opposite each other. The sealing assembly 30 includes a sealing plate 301, which is in contact with the circumferential side wall of the mixing roller 20. The sealing plate 301 has a second inlet / outlet 302 that can communicate with the first inlet / outlet 203. The first driving assembly 60 includes a slide rod 601, a second elastic element 603, a first support 604, and a second support 605. The first support 604 is fixedly mounted on the circumferential side wall of the mixing roller 201, the second support 605 is fixedly mounted on one end of the sealing plate 301, the first support 604 and the second support 605 are distributed opposite to each other, one end of the slide rod 601 is fixedly connected to the second support 605, and the other end passes through the first support 604 and extends to the side of the vertical plate 101. An annular stop 602 is fixedly mounted on the outside of the slide rod 601, and one end of the second elastic member 603 is connected to the first support 604 and the other end is connected to the annular stop 602.

[0037] When the mixing roller 20 rotates, causing a set of mixing chambers 201 to rotate upwards, the slide rod 601 corresponding to that mixing chamber 201 acts on the first arc-shaped block 102 located at the upper position. The first arc-shaped block 102 pushes the slide rod 601, causing the slide rod 601 to slide relative to the first support 604, thereby driving the sealing plate 301 to move along the circumferential side wall of the mixing roller 20, so that the second inlet / outlet 302 communicates with the first inlet / outlet 203. Subsequently, the bottom of the storage cylinder 40... The solenoid valve in the discharge pipe opens, and the cementitious powder material in the storage cylinder 40 enters the mixing chamber 201 through the discharge pipe, the second inlet / outlet 302, and the first inlet / outlet 203, realizing automatic feeding of the cementitious powder material. After the cementitious powder material in the mixing chamber 201 has been fed, the solenoid valve in the discharge pipe at the bottom of the storage cylinder 40 closes, thereby stopping the continued conveying of the cementitious powder material. Subsequently, as the mixing roller 20 continues to rotate, the slide bar 601 and the first arc located above... When block 102 separates, the second elastic element 603 pushes the annular stop 602, which in turn causes the slide rod 601 to slide in the opposite direction to the first support 604. The slide rod 601 causes the sealing plate 301 to move along the circumferential side wall of the mixing roller 20, so that the second inlet / outlet 302 is misaligned with the first inlet / outlet 203. At this time, the sealing plate 301 seals the first inlet / outlet 203, thereby preventing the leakage of the cementitious powder raw material in the mixing chamber 201. When a certain set of mixing chambers 201 is in After the cementitious powder raw material is mixed and rotated to a downward position, a set of first arc-shaped blocks 102 located at the bottom pushes the slide rod 601, which in turn drives the sealing plate 301 to move along the circumferential side wall of the mixing roller 20, so that the second inlet / outlet 302 and the first inlet / outlet 203 are connected again. At this time, the mixed cementitious powder raw material in the mixing chamber 201 is discharged through the connected second inlet / outlet 302 and the first inlet / outlet 203, realizing the automatic unloading of the cementitious powder raw material.

[0038] Please see Figure 4 as well as Figure 5 In one embodiment, a central chamber 202 is provided at the center of the mixing roller 20. The stirring assembly 50 includes a stirring shaft 501, stirring rods 502, and a power assembly. One end of the stirring shaft 501 extends into the mixing chamber 201, and the other end extends into the central chamber 202. Several sets of stirring rods 502 are provided, and several stirring rods 502 are fixedly mounted on the shaft of the stirring shaft 501 located inside the mixing chamber 201. The power assembly is located inside the central chamber 202. When the mixing roller 20 rotates, the power assembly is used to drive the stirring shaft 501 to rotate, thereby driving several stirring rods 502 to rotate, so as to stir and mix the cementitious powder raw material in the mixing chamber 201.

[0039] Please see Figure 3 as well as Figure 5 In one embodiment, a plurality of second arc-shaped blocks 103 are fixedly disposed on the side wall of the upright plate 101. The plurality of second arc-shaped blocks 103 are distributed at intervals in an arc-shaped structure. The power assembly includes a gear 503, a rack 504 and a first elastic element 505. The gear 503 is fixedly disposed on the shaft of the stirring shaft 501 located in the central chamber 202. The rack 504 is disposed on one side of the gear 503 and meshes with the gear 503. One end of the rack 504 is connected to the inner wall of the central chamber 202 through the first elastic element 505, and the other end passes through the end of the mixing roller 20 and extends to the side of the upright plate 101. The rack 504 is distributed along the axis of the mixing roller 20. The first elastic element 505 is used to provide elastic support for the rack 504.

[0040] After a certain set of mixing chambers 201 moves away from the position below the storage cylinder 40, the end of the rack rod 504 corresponding to the mixing chamber 201 acts on several second arc-shaped blocks 103. With the pushing action of the several second arc-shaped blocks 103 on the rack rod 50 and the elastic support action of the first elastic element 505 on the rack rod 504, the rack rod 504 can reciprocate along the axis of the mixing roller 20. When the rack rod 504 reciprocates, it drives the stirring shaft 501 to rotate forward and backward through the meshing action with the gear 503, which in turn drives several stirring rods 502 to rotate forward and backward, so as to stir the cementitious powder material in the mixing chamber 201 in both directions. It should be noted that when the stirring rods 502 rotate to stir the cementitious powder material, as the mixing roller 20 rotates itself, the cementitious powder material itself can also be turned over inside the mixing chamber 201 under the action of gravity. Combined with the stirring action of the stirring rods 502, the cementitious powder material can obtain a sufficient stirring effect.

[0041] Please see Figure 3 In one embodiment, the second drive assembly 70 includes a motor 701 and a rotating shaft 702. The motor 701 is fixedly mounted on the side wall of the upright plate 101. One end of the rotating shaft 702 is connected to the output end of the motor 701, and the other end is connected to the end of the mixing roller 20.

[0042] The motor 701 drives the rotating shaft 702 to rotate intermittently, which in turn drives the mixing roller 20 to rotate intermittently, so that several mixing chambers 201 rotate sequentially to the position below the storage cylinder 40, thereby realizing the sequential feeding of the adhesive powder raw material.

[0043] In one embodiment, the first elastic element 505 and the second elastic element 603 can be springs or metal sheets, and there is no limitation here.

[0044] In one embodiment, the inner wall of the mixing chamber 201 away from the central chamber 202 has an arc-shaped structure. Thus, when the mixing chamber 201 rotates to face downwards, the mixed cementitious powder material in the mixing chamber 201 can act on the arc-shaped inner wall, and then gather from the arc-shaped inner wall to the first inlet / outlet 203, and then be smoothly discharged through the first inlet / outlet 203 and the second inlet / outlet 302, thereby avoiding the residue of cementitious powder material inside the mixing chamber 201 and improving the discharge effect.

[0045] In this embodiment of the invention, when mixing of cementitious powder raw materials is required, several different cementitious powder raw materials can be placed inside the storage cylinder 40. Then, the second drive component 70 drives the mixing roller 20 to rotate intermittently, causing several mixing chambers 201 to be rotated sequentially to an upward position. When a certain set of mixing chambers 201 is rotated to an upward position, the mixing chamber 201 is located directly below the storage cylinder 40. The sealing component 30 corresponding to the mixing chamber 201 is controlled to move by the corresponding first drive component 60, thereby opening the first inlet / outlet 203 corresponding to the mixing chamber 201. Subsequently, the solenoid valve in the discharge pipe at the bottom of the storage cylinder 40 opens, thereby outputting the cementitious powder raw materials through the discharge pipe and then entering the mixing chamber 201 through the opened first inlet / outlet 203, realizing automatic feeding of cementitious powder raw materials. After the mixing chamber 201 has been fed for a certain period of time, the second drive component 70 drives the mixing roller 20 to rotate again. At this time, the mixing chamber 201 originally located below the storage cylinder 40 rotates away. The next set of mixing chambers 201 rotates to a position below the storage cylinder 40. After the mixing chambers 201 rotate away from the position below the storage cylinder 40, the first drive assembly 60 drives the sealing assembly 30 to move in the opposite direction to close the first inlet / outlet 203. Subsequently, the stirring assembly 50 starts working to stir the cementitious powder raw material. The next set of mixing chambers 201 that rotates to the position below the storage cylinder 40 continues to be fed. After a certain period of stirring, the cementitious powder raw material in a certain set of mixing chambers 201 is stirred, that set of mixing chambers... When 201 rotates downwards, the first drive assembly 60 drives the sealing assembly 30 to move again, thereby reopening the first inlet / outlet 203. The mixed cementitious powder material located in the mixing chamber 201 is output from the first inlet / outlet 203, realizing the automatic unloading of the cementitious powder material. Compared with the prior art, it can realize the automatic feeding, automatic mixing and unloading of cementitious powder material, thereby shortening the mixing time between two adjacent batches of cementitious powder material and improving the mixing efficiency of cementitious powder material.

[0046] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
