Description

Technical Field

[0001] This invention relates to the field of mixing plant technology, specifically a foundation-free multipurpose mixing plant. Background Technology

[0002] A concrete mixing plant is a complete set of equipment that mixes cement, aggregates, water and admixtures in a certain proportion to produce concrete that meets engineering requirements. It is widely used in construction fields such as buildings, roads and bridges. A traditional concrete mixing plant usually consists of a material storage system, a weighing system, a conveying system, a mixing host and a control system. Existing concrete mixers typically use a rotating spiral blade for mixing, and water is added during the mixing process. However, adding water directly causes water to remain on the surface of the material, requiring the rotation of the spiral blade to mix the material with the water. This results in uneven mixing of the material and water, which easily leads to clumping. Furthermore, blockages or residues are prone to occur when discharging the material after mixing, affecting production efficiency and the quality of concrete mixing. Summary of the Invention

[0003] The purpose of this invention is to provide a foundation-free multi-purpose mixing plant to solve the problem in the prior art where direct water addition causes water to remain on the surface of the material, resulting in uneven mixing of the material and water.

[0004] To achieve the above objectives, the present invention provides the following technical solution: A foundation-free multipurpose mixing plant includes: a cement mixing silo, a batching silo, and a continuous mixer. The cement mixing silo and the batching silo are connected to the continuous mixer via a conveyor belt. The plant also includes a closed conveyor belt and a concrete mixer. The concrete mixer is located on the side of the continuous mixer away from the closed conveyor belt. One end of the closed conveyor belt is connected to the continuous mixer, and the other end of the closed conveyor belt is connected to the concrete mixer. The concrete mixer is equipped with a mixing assembly, which consists of a power component, a rotating shaft, a multi-layer plate, and a spiral plate. The power component is located at the top of the concrete mixer, and the rotating shaft is connected to the power component. The multi-layer plate and the spiral plate are both connected to the rotating shaft. A discharge port is provided at the bottom of the multi-layer plate. A fixed plate and a rotating plate are provided on the side of the discharge port near the multi-layer plate, and the rotating plate is rotatably connected to the fixed plate. The concrete mixer is mounted on a support platform, and a pump is installed on the outside of the concrete mixer. The pump is connected to the inside of the concrete mixer through a pipeline.

[0005] The mixed cement in the mixing silo and the aggregate in the batching silo are conveyed to the continuous mixer via a conveyor belt. The continuous mixer mixes the mixed cement and aggregate to form a mixture. After mixing is completed, the mixed cement and aggregate are conveyed to the concrete mixer via a closed conveyor belt. When the mixture is delivered to the concrete mixer, the controller activates the power unit, which drives the rotating shaft. During rotation, the shaft drives the multi-layer plates and the spiral plate. When the shaft rotates forward, the spiral plate is in a mixing state, ensuring the mixture is only stirred and mixed within the concrete mixer. Simultaneously, the pump extracts the mixed water and delivers it to the mixer via pipeline. The forward rotation of the multi-layer plates and the spiral plate ensures thorough mixing of the mixture and water. After mixing is complete, the controller reverses the power unit, causing the rotating shaft to reverse as well. This reverse rotation allows the spiral plate to perform a conveying action, transporting the mixed concrete towards the discharge port. During concrete conveying, the controller activates the rotating plate, which rotates to a position below the fixed plate, creating a conveying gap. The concrete is then output through this gap.

[0006] Preferably, the multilayer plate consists of an upper plate and a lower plate, with a spiral plate located between the upper and lower plates. The spiral plate is connected to the upper plate, and the lower plate is connected to the concrete mixer. The spiral plate is rotatably connected to the lower plate. The cross-sections of the upper and lower plates are isosceles trapezoids. Several rotating plates are provided on the side of the upper plate away from the lower plate. The lower plate is connected to the discharge port.

[0007] After the mixture enters the concrete mixer, it first sits between the multi-layer plate and the inner wall of the concrete mixer. Then, the rotating shaft drives the upper plate to rotate, and the rotation of the upper plate drives the spiral plate to rotate. Since the rotating shaft is in the forward rotation process, the spiral plate pushes the mixture out of the space between the upper and lower plates. The mixture can only be stirred on the outside of the multi-layer plate. Since there are several rotating blades on the side of the upper plate away from the lower plate, the rotating blades and the spiral plate cooperate with each other to achieve the mixing of the mixture and the water. After the mixture is mixed and concrete is formed, the rotating shaft reverses under the action of the power component, causing the rotating shaft to drive the upper plate and the spiral plate to reverse. In turn, the spiral plate reverses and drives the concrete conveying, so that the concrete is conveyed from the inside of the concrete mixer to the space between the upper and lower plates. Then, the concrete flows under the conveying action of the spiral plate and is conveyed from the space between the upper and lower plates to the space between the lower plate and the discharge port. That is, the concrete is conveyed to the discharge port along with the lower plate.

[0008] Preferably, a stirring body is provided on the top of the multilayer plate. The stirring body is connected to a rotating shaft. The stirring body consists of two rotating plates arranged vertically along the longitudinal direction. Several radial strips are arranged around the rotating plates and are arranged around the axis of the rotating plates.

[0009] The mixture is conveyed to the concrete mixer by a closed conveyor belt. When the mixture is input, it first encounters the mixing body. After the power unit is started, the power unit drives the rotating shaft to rotate, which in turn drives two rotating plates to rotate. During the rotation of the two rotating plates, several radial strips rotate, so that the radial strips can agitate and mix the mixture during the forward rotation, and can push the concrete to move during the reverse rotation, so that the concrete is conveyed from the radial strips to the spiral plate.

[0010] Preferably, the length of the radial strip on the upper rotating plate is shorter than the length of the radial strip on the lower rotating plate.

[0011] This design makes the mixing body conical, and similarly, the connecting pipes are also conical, so that the mixing body can prevent the mixture from overflowing from the inlet of the concrete mixer when mixing the mixture and water.

[0012] Preferably, a plurality of connecting pipes are provided between the two rotating plates, and two connecting pipes are provided on each of the radiation strips. The two connecting pipes are arranged at equal intervals along the side of the radiation strip, and the plurality of connecting pipes are arranged crosswise between the plurality of radiation strips.

[0013] As the two rotating plates rotate, they drive several radial strips to rotate, which in turn drive several connecting pipes to rotate. This causes the connecting pipes to revolve around the axis of the rotating shaft, thereby agitating and mixing the mixture inside the concrete mixer. In this way, the radial strips, multi-layer plates, spiral plates, and connecting pipes work together to vertically agitate and mix the concrete along the axis of the rotating shaft, thus further improving the mixing effect of the concrete.

[0014] Preferably, the rotating shaft and the rotating plate located above are provided with flow channels, the flow channels are connected to the pump through pipes, and the surface of the connecting pipe is provided with a plurality of water inlets, the water inlets are connected to the flow channels through connecting pipes.

[0015] As the connecting pipe revolves around the rotating shaft, the controller starts the pump, which draws in the mixed water. This mixed water is then transported through pipes to the rotating shaft and the flow channels within the rotating plate above. From there, it flows back to the connecting pipe and finally through the inlet on the connecting pipe into the concrete mixer. This means that as the mixture enters the mixer, the connecting pipe outputs mixed water, allowing for the addition of water during mixing. This simultaneous addition of water and mixing ensures that when the mixture submerges the connecting pipe, the water output is located within the mixture, achieving a water delivery effect from the inside out. This prevents clumping and uneven mixing, further improving the quality of the mixture. Because the connecting pipe is located at the top of the upper plate, the water output from it can flow from top to bottom, towards the bottom of the concrete mixer, allowing for thorough penetration and mixing of the mixture at all points.

[0016] Preferably, a vibrating rod is provided on the side of the lower radial strip near the multilayer plate, and a vibration generator is provided inside the vibrating rod.

[0017] The vibrating bar located below the radiation strip rotates with the rotation of the radiation strip, causing several vibrating bars to revolve around the axis of rotation. During the rotation of the vibrating bar, the controller controls the vibration generator inside to start. After the vibration generator starts, it generates vibration, and then the vibration source is transmitted to the mixture through the vibrating bar. When the rotating shaft is rotating forward, the concrete mixer is in the mixing stage. The vibration transmitted by the vibrator is applied to the solid and liquid, making the solid molecules and liquid molecules move more closely, thereby further improving the mixing effect of the mixture and the water. When the rotating shaft is in reverse, the concrete mixer is in the concrete output stage. The vibration transmitted by the vibrator is applied to the concrete, which makes the concrete quickly conveyed to the discharge port under the action of vibration. This prevents some concrete from adhering to the inner wall of the concrete mixer or the outer wall of the mixing body, thus ensuring the stable delivery of concrete.

[0018] Preferably, a spray pipe is provided at the top of the enclosed conveyor belt, and the spray pipe is connected to the pump.

[0019] During the conveying process of the closed conveyor belt, the pump also delivers the mixed water to the spray pipe through the pipeline, so that the spray pipe sprays the mixed material being conveyed. The sprayed water not only reduces dust in the mixed material during the conveying stage, preventing dust from flying around, but also pre-wets the mixed material, so that the wet mixed material can be more quickly and fully mixed with the mixed water in the concrete mixer.

[0020] Compared with the prior art, the beneficial effects of the present invention are: 1. The connecting pipe outputs mixed water, allowing water to be added to the mixture during the mixing process. This enables simultaneous water addition and mixing. When the mixture submerges the connecting pipe, the water output from the pipe is located inside the mixture, achieving a water delivery effect from the inside to the outside. This prevents clumping and uneven mixing, further improving the quality of the mixture. Because the connecting pipe is located at the top of the upper plate, the water output from the connecting pipe can flow from top to bottom, i.e., from the connecting pipe to the bottom of the concrete mixer, allowing the water to penetrate and mix the mixture at various points.

[0021] 2. During the rotation of the vibrator, the controller activates the internal vibration generator, which generates vibration. This vibration is then transmitted to the mixture through the vibrator. When the shaft rotates forward, the concrete mixer is in the mixing stage. The vibration transmitted by the vibrator is applied to the solids and liquids, making the solid and liquid molecules move more closely together, thus further improving the mixing effect of the mixture and water. When the shaft rotates in reverse, the concrete mixer is in the concrete output stage. The vibration transmitted by the vibrator is applied to the concrete, causing it to be quickly conveyed to the discharge port under the action of vibration. This prevents some concrete from adhering to the inner wall of the concrete mixer or the outer wall of the mixing body, thus ensuring stable concrete delivery. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-4 The first embodiment of the present invention shown is a foundation-free multi-purpose mixing plant, comprising: a cement mixing silo, a batching silo, and a continuous mixer. The cement mixing silo and the batching silo are connected to the continuous mixer via a conveyor belt. The plant also includes a closed conveyor belt 1 and a concrete mixer 2. The concrete mixer 2 is located on the side of the continuous mixer away from the closed conveyor belt 1. One end of the closed conveyor belt 1 is connected to the continuous mixer, and the other end of the closed conveyor belt 1 is connected to the concrete mixer 2. The concrete mixer 2 is equipped with a mixing assembly 21, which consists of a power component (the power component is a motor), a rotating shaft 22, a multi-layer plate 23, and a spiral plate 24. The power component is located at the top of the concrete mixer 2, and the rotating shaft 22 is connected to the power component. The multi-layer plate 23 and the spiral plate 24 are both connected to the rotating shaft 22. A discharge port 25 is provided at the bottom of the multi-layer plate 23. A fixed plate 251 and a rotating plate 252 are provided on the side of the discharge port 25 near the multi-layer plate 23. The rotating plate 252 is rotatably connected to the fixed plate 251 (the rotating plate 252 is driven by a motor to engage gears and tooth grooves). The concrete mixer 2 is mounted on a support platform, and a pump is mounted on the outside of the concrete mixer 2. The pump is connected to the inside of the concrete mixer 2 through a pipeline.

[0026] In one specific embodiment of the present invention, the multilayer plate 23 is composed of an upper plate 231 and a lower plate 232, and the spiral plate 24 is located between the upper plate 231 and the lower plate 232. The spiral plate 24 is connected to the upper plate 231, and the lower plate 232 is connected to the concrete mixer 2. The spiral plate 24 is rotatably connected to the lower plate 232. The cross-sections of the upper plate 231 and the lower plate 232 are isosceles trapezoids. A plurality of rotating plates are provided on the side of the upper plate 231 away from the lower plate 232. The lower plate 232 is connected to the discharge port 25.

[0027] In one specific embodiment of the present invention, a spray pipe is provided on the top of the closed conveyor belt 1, and the spray pipe is connected to the pump.

[0028] like Figures 5-8 The second embodiment of the present invention shown provides a stirring assembly different from that of the first embodiment. The difference is that in this embodiment, a stirring body 29 is provided above the multilayer plate 23. The stirring body 29 includes a rotating body 26, a connecting pipe 27, and a vibrating rod 28. The conical rotating body 26 and several connecting pipes 27 are used to make the several connecting pipes 27 revolve around the rotating axis 22. During the revolve of the connecting pipes 27, the mixture and the mixed water are stirred. At the same time, the mixed water is output from the water outlet of the connecting pipe 27, so that the mixed water directly enters the interior of the mixture and permeates from the inside to the outside. The mixing is coordinated with the vibration generated by the vibrating rod 28, thereby accelerating the stirring of the mixture and the mixed water.

[0029] The specific content is as follows: In one specific embodiment of the present invention, a stirring body 29 is provided on the top of the multilayer plate 23. The stirring body 29 is connected to the rotating shaft 22. The stirring body 29 is composed of two rotating plates 26. The two rotating plates 26 are arranged vertically along the longitudinal direction. A plurality of radial strips 261 are arranged around the rotating plates 26. The plurality of radial strips 261 are arranged around the axis of the rotating plates 26.

[0030] In one specific embodiment of the present invention, the length of the radial strip 261 located on the upper rotating plate 26 is less than the length of the radial strip 261 located on the lower rotating plate 26.

[0031] In one specific embodiment of the present invention, a plurality of connecting pipes 27 are provided between the two rotating plates 26, and two connecting pipes 27 are provided on each of the radial strips 261. The two connecting pipes 27 are arranged at equal intervals along the side of the radial strip 261, and the plurality of connecting pipes 27 are arranged crosswise between the plurality of radial strips 261.

[0032] In one specific embodiment of the present invention, the rotating shaft 22 and the rotating plate 26 located above are provided with flow channels, the flow channels are connected to the pump through pipes, and the surface of the connecting pipe 27 is provided with a plurality of water inlets, the water inlets are connected to the flow channels through the connecting pipe 27.

[0033] In one specific embodiment of the present invention, a vibrating rod 28 is provided on the side of the radial strip 261 near the multilayer plate 23, and a vibration generator is provided inside the vibrating rod 28.

[0034] Working principle of the invention: The mixed cement in the mixing silo and the aggregate in the batching silo are conveyed to the continuous mixer via a conveyor belt. The continuous mixer mixes the mixed cement and aggregate to form a mixture. After mixing, the mixed cement and aggregate are conveyed to the concrete mixer 2 via a closed conveyor belt 1. During the conveying process of the closed conveyor belt 1, the pump also conveys the mixing water to the spray pipe through the pipeline, so that the spray pipe sprays the mixture being conveyed. The sprayed water not only reduces dust in the mixture during the conveying stage, preventing dust from flying around, but also pre-wets the mixture, so that the wet mixture can be more quickly and fully mixed with the mixing water in the concrete mixer 2. The mixture is conveyed to the concrete mixer 2 by the closed conveyor belt 1. When the mixture is input, it will first encounter the mixing body 29. After the power unit is started, the power unit drives the rotating shaft 22 to rotate. The rotating shaft 22 drives the two rotating plates 26 to rotate. During the rotation of the two rotating plates 26, the two rotating plates drive several radial strips 261 to rotate. This allows the radial strips 261 to stir and mix the mixture during the forward rotation. During the reverse rotation, the radial strips 261 can push the concrete to move, so that the concrete is conveyed from the radial strips 261 to the spiral plate 24. The mixing body 29 is made into a cone shape, and similarly, several connecting pipes 27 are also made into cone shapes, so that the mixing body 29 can prevent the mixture from overflowing from the inlet of the concrete mixer 2 when mixing the mixture and the water. During the rotation of the two rotating plates 26, several radial strips 261 are driven to rotate, and the radial strips 261 drive several connecting pipes 27 to rotate, so that the connecting pipes 27 revolve around the axis of the rotating shaft 22. In the process of revolving, the connecting pipes 27 agitate and mix the mixture in the concrete mixer 2. Thus, the radial strips 261, multi-layer plates 23, spiral plates 24 and several connecting pipes 27 cooperate with each other to perform vertical agitation and mixing along the axial direction of the rotating shaft 22. As the connecting pipe 27 revolves around the rotating shaft 22, the controller starts the pump, which draws in the mixed water. The mixed water is then transported through the pipe to the flow channels within the rotating shaft 22 and the rotating plate 26 above it. From there, it flows through the flow channels back to the connecting pipe 27, and finally through the water outlet on the connecting pipe 27 into the concrete mixer 2. This allows the connecting pipe 27 to output mixed water after the mixture enters the concrete mixer 2, enabling the addition of mixed water during the mixing process and achieving simultaneous water addition and mixing. During the process, when the mixture submerges the connecting pipe 27, the mixed water output from the connecting pipe 27 is located inside the mixture, thus achieving the effect of water delivery from the inside to the outside, thereby avoiding the phenomenon of caking and uneven mixing of the mixture, and further improving the quality of the mixture mixing; since the connecting pipe 27 is located at the top of the upper plate 231, the mixed water output from the connecting pipe 27 can flow from top to bottom, that is, from the connecting pipe 27 to the bottom of the concrete mixer 2, so that the mixed water can penetrate and mix at various locations of the mixture; The vibrating rod 28 located on the lower radial strip 261 rotates with the rotation of the radial strip 261, causing several vibrating rods 28 to also revolve around the axis of the rotating shaft 22. During the rotation of the vibrating rod 28, the controller controls the vibration generator set inside it to start. After the vibration generator starts, it generates vibration, and then the vibration source is transmitted to the mixture through the vibrating rod 28. When the rotating shaft 22 is rotating forward, the concrete mixer 2 is in the mixing stage, and the vibration transmitted by the vibrator 28 will be applied to the solid and liquid, making the solid molecules and liquid molecules move more closely. After the mixture enters the concrete mixer 2, it first sits between the multi-layer plate 23 and the inner wall of the concrete mixer 2. Then, the rotating shaft 22 drives the upper plate 231 to rotate. During the rotation of the upper plate 231, the spiral plate 24 rotates. Since the rotating shaft 22 is in the forward rotation process, the spiral plate 24 pushes the mixture out from the space between the upper plate 231 and the lower plate 232 when it rotates. The mixture can only be stirred outside the multi-layer plate 23. Since there are several rotating blades on the side of the upper plate 231 away from the lower plate 232, the rotating blades and the spiral plate 24 cooperate with each other to achieve the mixing treatment of the mixture and the water. After the mixture is mixed and concrete is formed, the rotating shaft 22 reverses under the action of the power component. At this time, the concrete mixer 2 is in the concrete output stage, which causes the rotating shaft 22 to drive the upper plate 231 and the spiral plate 24 to reverse. Then, the spiral plate 24 reverses and drives the concrete conveying, so that the concrete is conveyed from the inside of the concrete mixer 2 to the space between the upper plate 231 and the lower plate 232. Then, the concrete flows under the conveying action of the spiral plate 24. The concrete is conveyed from the space between the upper plate 231 and the lower plate 232 to the space between the lower plate 232 and the discharge port 25. That is, the concrete is conveyed to the discharge port 25 along with the lower plate 232. At the same time, the vibration transmitted by the vibrator 28 is applied to the concrete, so that the concrete is quickly conveyed to the discharge port 25 under the action of vibration, avoiding some concrete from adhering to the inner wall of the concrete mixer 2 or the outer wall of the mixing body 29, thereby ensuring the stable conveying of concrete.

[0035] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
