Description

Technical Field

[0001] The utility model relates to the technical field of concrete production equipment, and particularly to a powder mixing and stirring system. Background Art

[0002] Concrete generally refers to an engineering composite material in which aggregate is cemented into a whole by a cementing material. Usually, the term "concrete" refers to cement concrete, also known as ordinary concrete, which is made of cement as the cementing material, sand and stone as the aggregate, and is mixed with water (which may contain additives and admixtures) in a certain proportion. It is widely used in civil engineering. Concrete has the characteristics of rich raw materials, low price, and simple production process, so its consumption is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make its application range very wide. It is not only used in various civil engineering projects, but also an important material in the shipbuilding industry, mechanical industry, ocean development, geothermal engineering, etc.

[0003] In the production process of concrete or concrete admixtures, several different materials are generally mixed, so a mixing and stirring device is needed. However, it is inconvenient to weigh the addition amount of each powder material in the existing mixing and stirring device, resulting in difficulty in controlling the powder ratio. At the same time, there is generally only one packaging structure for packing the finished powder material, with low efficiency. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a powder mixing and stirring system to solve the problems of inconvenient weighing in the existing powder stirring and mixing device and low efficiency of the packaging structure.

[0005] The technical solution adopted by the utility model is as follows: A powder mixing and stirring system includes a feeding part, a mixing part, and a discharging part connected in sequence. The feeding part includes a plurality of first storage bins connected to each other and a feeding mechanism. A weighing part is also arranged between the feeding part and the mixing part. The weighing part includes a weighing support and a weighing box. A weighing sensor is arranged between the weighing box and the weighing support. A first lifting mechanism is arranged between the weighing box and the first storage bin. The mixing part includes a mixing box. A second lifting mechanism is arranged between the mixing box and the weighing box. The discharging part includes a finished product bin, a first discharging mechanism for bagging the powder material, and a second discharging mechanism for directly loading the powder material onto a vehicle. The finished product bin is located below the mixing box and is connected to the mixing box. The first discharging mechanism is located below the finished product bin. The second discharging mechanism is located on the side of the finished product bin, and the second discharging mechanism is connected to the finished product bin through a third lifting mechanism. The system also includes a control system, and the feeding part, the mixing part, the discharging part, and the weighing part are all connected to the control system.

[0006] After adopting the above structure, the following beneficial effects are achieved:

[0007] 1. A number of first storage bins can convey and store different types of powder materials through a feeding mechanism, and send them to a weighing box through a first lifting mechanism. The weight of the materials is monitored by a weighing sensor. When the weight of the materials reaches the required value, the feeding is stopped through the control system, and at the same time, the feeding of another type of powder material starts. By such a feeding method, not only the weighing efficiency is improved, but also the weight ratio of each material can be accurately limited, improving the product quality.

[0008] 2. The weighing box sends the powder materials in a determined ratio into the mixing box through a second lifting mechanism for mixing, and the finished products after mixing enter the finished product bin below the mixing box for storage and waiting for packaging. In this way, the mixing process will not affect the efficiency of the packaging process, improving the production efficiency of the product.

[0009] 3. In the discharging part, the original single packaging discharging port is divided into a first discharging mechanism for bagging and a second discharging port that can directly load the materials in bulk onto a vehicle. It can not only realize the work of bagging the powder materials, but also directly load the materials onto a vehicle when a large quantity of bulk loading is required, improving the shipping efficiency.

[0010] Preferably, the first discharging mechanism includes a first discharging box, a first discharging port extending to the outside of the first discharging box is arranged on the first discharging box, and a clamping assembly is arranged above the first discharging port.

[0011] The first discharging port extending to the outside of the first discharging box can be used to sleeved with a packaging bag, and the packaging bag is clamped at the first discharging port through the clamping assembly. Such a setting can prevent the powder materials from flying out of the packaging bag during the bagging process, reducing the waste of powder materials, ensuring the cleanliness of the workshop environment, and reducing the probability of health risks to the employees in the workshop due to dust flying.

[0012] Preferably, a weighing tray is arranged below the first discharging port, a first driving assembly for assisting in discharging is arranged in the first discharging port, the weighing tray is connected with the first driving assembly, and the weighing tray, the clamping assembly and the first driving assembly are all connected with the control system.

[0013] The first driving assembly adopts a screw conveyor, which can continuously push the materials in the first discharging box out of the first discharging port, effectively improving the discharging efficiency. The weighing tray can monitor the weight of the packaging bag in real time. When the weight of the powder materials in the packaging bag reaches the set requirement, the control system can automatically stop the first driving assembly and stop discharging, ensuring that the weight of each bag of powder materials is the same.

[0014] Preferably, an adjusting plate is further provided on the first discharge box. An adjusting hole in the vertical direction is provided on the adjusting plate. The weighing tray is slidably connected in the adjusting hole, and a locking mechanism for locking the weighing tray is provided between the weighing tray and the adjusting plate.

[0015] The setting of the adjusting plate can adjust the weighing height according to the size of the packaging bag, and the position of the weighing tray is fixed through the locking mechanism, which ensures that the weighing tray can stably support the packaging bag and also ensures stable and accurate weighing results.

[0016] Preferably, the second discharge mechanism includes a second discharge rack and a second storage barrel installed on the second discharge rack. The discharge end of the second storage barrel is located at the bottom, and a receiving platform for parking the transport vehicle is provided below the second storage barrel.

[0017] The second discharge rack can support the second storage barrel, and the receiving platform can be used for parking the transport vehicle and receiving the finished powder material thrown from the second storage barrel.

[0018] Preferably, a secondary material feeding port is further provided on the second lifting mechanism.

[0019] In order to improve the quality of the finished product, some secondary materials need to be added to the powder material. The secondary material feeding port provided on the second lifting mechanism can add a small amount of secondary materials before the powder materials are mixed. This not only facilitates and intuitively adds the secondary materials, but also is convenient for controlling the addition amount of the secondary materials. At the same time, it saves the cost of equipment and improves economic benefits.

[0020] Preferably, the feeding mechanism includes a feeding port opened on the ground and a fourth lifting mechanism for connecting the feeding port and the first storage barrel. The fourth lifting mechanism is also connected with a material distribution pipeline. The merging end of the material distribution pipeline is connected with the fourth lifting mechanism, and the branch ends of the material distribution pipeline are respectively connected with one of the first storage barrels. A material distribution plate is rotatably connected in the material distribution pipeline.

[0021] Through the fourth lifting mechanism, the powder material put into the feeding port can be lifted to a high place and sent into the first storage barrel through the material distribution pipeline. At the same time, by switching the position of the material distribution plate in the material distribution pipeline, the material distribution pipeline can be connected to only one of the first discharge barrels. In this way, the function of feeding two or more first storage barrels by the same lifting mechanism is realized, which can not only achieve the required function, but also reduce the equipment cost.

[0022] Preferably, vibrators are connected to the first storage barrel and the second storage barrel.

[0023] When the first storage bucket feeds materials into the weighing box and the second storage bucket loads the materials onto the vehicle, the vibrator continuously drives the first storage bucket and the second storage bucket to vibrate, enabling the powder to quickly move towards the bottom of the first storage bucket and the second storage bucket, improving the feeding efficiency and avoiding the situation of powder adhering to the side walls of the first storage bucket or the second storage bucket.

[0024] Preferably, the first storage bucket is further connected with a first dust removal mechanism, which includes a negative pressure dust collector and a first dust removal bucket cover. The first dust removal bucket cover is in the shape of an inverted funnel and extends into the first storage bucket.

[0025] The first dust removal bucket cover extends into the first storage bucket from the top of the first storage bucket, and adsorbs the flying dust in the first storage bucket through the negative pressure continuously generated by the negative pressure dust collector, avoiding the dust flying from the first storage bucket into the workshop during the feeding and discharging processes, and improving the environmental conditions inside the workshop.

[0026] Preferably, the second storage bucket is further connected with a second dust removal mechanism, which includes a negative pressure dust collector and a second dust removal bucket cover. The second dust removal bucket cover is in the shape of an inverted funnel and extends into the second storage bucket. A negative pressure dust removal port pipe is also installed on the second discharge rack, and the pipe orifice of the negative pressure dust removal pipe is arranged towards the receiving platform. A lifting component is also arranged on the receiving platform, and the pipe orifice of the negative pressure pipe is connected to the second discharge rack through the lifting component.

[0027] The second dust removal bucket cover extends into the second storage bucket from the top of the second storage bucket, adsorbs the flying dust in the second storage bucket through the negative pressure dust collector, and at the same time, the negative pressure dust removal pipe can adsorb the flying dust during the process of loading the powder onto the vehicle, avoiding the dust flying in the workshop and reducing the impact of the dust on the environment inside the workshop and the health of workers.

Specific embodiments

[0036] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0037] Embodiment 1

[0038] According to the specification appendix Figures 1-4As shown in the figure, the utility model provides a powder mixing and stirring system, which includes a feeding part 10, a mixing part, a weighing part 30 and a discharging part connected in sequence. The feeding part 10 includes several first storage bins 11 and a feeding mechanism 60 for conveying powder to the first storage bins 11. The several first storage bins 11 can store a variety of different raw materials; the weighing part 30 includes a weighing support 31, weighing sensors 33 and a weighing box 32. The weighing box 32 is connected to the weighing support 31 through four weighing sensors 33. In this embodiment, the weighing sensors 33 are uniformly arranged on the four outer sides of the weighing box 32, which can not only stably support the weighing box 32, but also ensure accurate weighing data, reduce weighing errors. A first lifting mechanism 12 is arranged between the weighing box 32 and the first storage bin 11, and the material in the first storage bin 11 is transported to the weighing box 32 through the first lifting mechanism 12; the mixing part includes a mixing box 21, and the mixing box 21 is connected to the weighing box 32 through a second lifting mechanism 34. The material is transported to the mixing box 21 through the second lifting mechanism 34 for mixing work. The discharging part includes a finished product bin 22 connected below the mixing box 21 for storing the finished product material after mixing. The finished product bin 22 is also connected with a first discharging mechanism 40 and a second discharging mechanism 50. The first discharging mechanism 40 is located below the finished product bin 22, and the second discharging mechanism 50 is located on the side of the finished product bin 22. The second discharging mechanism 50 is connected to the finished product bin 22 through a third lifting mechanism 54.

[0039] In this embodiment, a control system is also provided. The feeding part 10, the mixing part, the discharging part and the weighing part 30 are all connected to the control system, and the first lifting mechanism 12, the second lifting mechanism 34 and the third lifting mechanism 54 are also connected to the control system. Through the setting of the control system, automatic control of the feeding, mixing and discharging processes can be realized, which is more rapid and accurate.

[0040] In this embodiment, the first discharging mechanism 40 includes a first discharging box 41 connected below the finished product box. There are two first discharging ports 42 extending to the outside of the first discharging box 41 on the front side of the first discharging box 41. A first driving component for assisting discharging is installed in the first discharging port 42. Above the first discharging port 42, there is also a clamping component 43 for clamping the packaging bag on the first discharging port 42. In this embodiment, the first driving component adopts a screw conveyor structure, and the clamping component 43 uses a cylinder to drive the clamping block to abut against the upper side of the first discharging port 42, thereby clamping the packaging. A regulating plate 45 is fixedly installed on the front side of the first discharging box 41. A regulating hole is provided in the regulating plate 45 along the vertical direction. A weighing tray 44 is slidably connected in the regulating hole. And a locking mechanism for locking the weighing tray 44 is provided between the weighing tray 44 and the regulating plate 45. The weighing tray 44 can weigh the packaging bag being filled and monitor the real-time weight of the packaging bag. The weighing tray 44, the clamping component 43, and the first driving component are all connected to the control system, so that when the weighing tray 44 detects that the weight of the packaging bag reaches the standard, it can automatically release the clamping component 43 and stop discharging, facilitating the packaging of the next bag of powder material.

[0041] The second discharging mechanism 50 includes a second discharging frame 51 and a second storage barrel 52 installed on the second discharging frame 51. The discharging end of the second storage barrel 52 is located at the bottom of the second storage barrel 52. And a receiving platform 53 for parking the transport vehicle is also provided below the second storage barrel 52.

[0042] Vibrators 13 are connected to the barrel walls of both the first storage barrel 11 and the second storage barrel 52. Through the vibrators 13, the first storage barrel 11 and the second storage barrel 52 can be driven to vibrate continuously, so that the materials in the first storage barrel 11 and the second storage barrel 52 can flow out quickly, improving the conveying and loading efficiency.

[0043] The feeding mechanism 60 includes a feeding port 61 opened on the ground and a fourth lifting mechanism 62 for connecting the feeding port 61 and the first storage barrel 11. A distributing pipe 63 is also connected to the upper end of the fourth lifting mechanism 62. The distributing pipe 63 is in a "Y" shape. One end of the distributing pipe 63 connected to the fourth lifting mechanism 62 is the merging section, and the other end of the distributing pipe 63 is the branch section. Each branch section is respectively connected to one of the first storage barrels 11. A distributing plate 64 is rotatably connected in the distributing pipe 63. The distributing plate 64 is also connected to a second driving member for driving the distributing plate 64 to move. In this embodiment, the fourth lifting mechanism 62 adopts a chain bucket elevator, and the second driving member adopts a motor.

[0044] Its working principle is as follows: during the feeding process, first, the raw materials are fed into the fourth lifting mechanism 62 through the feeding port 61. The raw materials follow the fourth lifting mechanism 62 into the material distribution pipeline 63. At this time, the movable end of the material distribution plate 64 closely adheres to the right side of the material distribution pipeline 63, so that the powder can only enter the first storage bucket 11 on the left. After the addition of this kind of powder is completed, the position of the material distribution plate 64 is switched, so that the material distribution pipeline 63 can only communicate with the first storage bucket 11 on the right. At this time, another kind of raw material can be replaced, enabling the feeding mechanism 60 to feed different kinds of raw materials into different first storage buckets 11;

[0045] During the mixing process, the powder in the first storage bucket 11 enters the weighing box 32 through the first lifting mechanism 12 in sequence. The weighing box 32 monitors the weight of the incoming powder. When the weight of the current raw material reaches the set standard, the current first lifting mechanism 12 is stopped, and another lifting mechanism is started to feed another kind of raw material until all the required raw materials are fed. Then, the second lifting mechanism 34 is started to transport the raw materials in the weighing box 32 to the mixing box 21 for stirring and mixing;

[0046] After the stirring and mixing are completed, the finished powder enters the finished product bin 22 below the mixing box 21 and is packaged according to actual packaging requirements. If bagging is required, the packaging bag is sleeved on the lower first discharge port 42, and the packaging bag is clamped at the first discharge port 42 through the clamping assembly 43. While discharging under the action of the first driving assembly, the weight of the packaging bag and the powder therein is monitored through the weighing tray 44. When the set packaging weight is reached, the discharging is stopped, and the clamping assembly 43 is unlocked to complete the bagging; if direct bulk powder loading is required, the third lifting mechanism 54 is started to transport the finished powder to the second storage bucket 52, and the transport vehicle is parked at the receiving platform 53 below the second storage bucket 52 for receiving, thus completing the loading work.

[0047] Embodiment 2

[0048] According to the appended drawings of the specification Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that an auxiliary material feeding port 35 is further provided on the second lifting mechanism 34. In this embodiment, the second lifting mechanism 34 adopts a screw conveyor mechanism. The auxiliary material feeding port 35 can directly add the required small amount of auxiliary materials to the first lifting mechanism 12 and send them to the mixing part through the first lifting mechanism 12 for mixing. This can effectively improve the quality of concrete or concrete admixtures, and at the same time reduce the investment in equipment funds and improve the economic benefits in the production process.

[0049] Embodiment 3

[0050] According to the appended drawings of the specification Figures 6-7As shown in the figure, the difference between this embodiment and Embodiment 1 is that the first storage barrel 11 is further connected with a first dust removal mechanism. The first dust removal mechanism includes a negative pressure dust collector 71 and a first dust removal barrel cover 72. The first dust removal barrel cover 72 is in the shape of an inverted funnel and extends into the first storage barrel 11.

[0051] The second storage barrel 52 is also connected with a second dust removal mechanism. The second dust removal mechanism includes a negative pressure dust collector 71 and a second dust removal barrel cover 73. The second dust removal barrel cover 73 is in the shape of an inverted funnel and extends into the second storage barrel 52. A negative pressure dust removal port pipeline is also installed on the second discharge rack 51. The nozzle of the negative pressure dust removal pipeline 74 is arranged towards the receiving platform 53. A lifting component 75 is also arranged on the receiving platform 53. The nozzle of the negative pressure dust removal pipeline 74 is connected with the second discharge rack 51 through the lifting component 75. In this embodiment, the lifting component 75 adopts a linear motor vertically installed on the second discharge rack 51. By driving the nozzle of the negative pressure dust removal pipeline 74 to lift through the linear motor, the dust removal height can be adjusted when loading trucks at different heights to ensure good and effective dust removal work. At the same time, three support arms are arranged on both the first dust removal barrel cover 72 and the second dust removal barrel cover 73. The support arms are lapped on the side walls of the first storage barrel 11 or the second storage barrel 52 to support the first dust removal barrel cover 72 and the second dust removal barrel cover 73.

[0052] The working principle of this embodiment is that during the feeding process of the powder material, there is often a situation of dust flying. Through the settings of the first dust removal mechanism and the second dust removal mechanism, the dust flying to the tops of the first storage barrel 11 and the second storage barrel 52 can be effectively adsorbed. At the same time, the second dust removal mechanism can also adsorb the dust flying to the outside of the transport vehicle during the powder material loading, reducing the situation of dust flying in the workshop and improving the safety of workers during the production process.
