Description

Technical Field

[0001] This utility model relates to the technical field of slag micronized powder processing equipment, and specifically discloses a batching device for slag micronized powder processing. Background Technology

[0002] Slag powder is a powdery substance produced by drying and grinding waste slag generated during pig iron smelting in steel plants. Its full name is granulated blast furnace slag powder, commonly known as mineral powder or water slag powder. Slag powder is often used in the fields of construction, soil improvement, filling materials, and preparation of other building materials. In the production process of slag powder, in order to obtain slag powder with different properties, it is usually necessary to use a batching device to batch different slag powder raw materials so as to initially mix the slag powder raw materials.

[0003] Chinese patent CN212383623U discloses a slag powder raw material batching device. Two partitions divide the top of the batching box into three feeding zones. Three metering bins are installed on the top of the batching box corresponding to the three feeding zones. A screen plate is set at the bottom of each feeding zone. A telescopic rod is vertically fixed to the left and right sides of the upper surface of the screen plate. A spring is fitted on each telescopic rod. The output shaft end of motor one is fixed to the right end of the horizontal shaft. Three eccentric blocks are fitted on the horizontal shaft corresponding to the three feeding zones. The top of the eccentric blocks contacts the lower end of the screen plate. The inner and outer ends of the inclined plate and the connecting plate are fixed to the inner walls of the inner and outer sides of the batching box, respectively. The inclined plate and the connecting plate form a conical bucket structure. The left end of the screw conveyor extends to the left of the batching box. A feeding pipe is connected to the connecting plate. The lower end of the feeding pipe is connected to the screw conveyor. The output shaft end of motor two is fixed to the end of the rotating shaft placed inside the screw conveyor. This utility model has the advantages of comprehensive functions and good performance. However, the above-mentioned batching device does not have the function of mixing and stirring slag powder raw materials during use. This means that after the raw materials are discharged from the discharge pipe, a mixing device is still needed to mix them to ensure that the raw materials are fully mixed. This increases the equipment cost of slag powder processing to a certain extent. In addition, the number of metering bins in the above-mentioned batching device cannot be adjusted according to the types and quantities of slag powder raw materials. When the number of raw material types is greater than the number of metering bins, different raw materials need to be metered in the same metering bin. The raw materials remaining on the inner wall of the metering layer can easily affect the accuracy of metering other types of raw materials, thereby affecting the quality of slag powder. Therefore, in order to solve the above problems, this utility model proposes a batching device for slag powder processing. Utility Model Content

[0004] This utility model aims to provide a batching device for slag powder processing, which has the functions of weighing and mixing slag powder raw materials. It can fully mix the slag powder raw materials before discharging them from the hopper, saving investment in slag powder processing equipment. The number of hoppers and weighing mechanisms can be adjusted according to the type of slag powder raw materials, avoiding multiple raw materials sharing one hopper, reducing the impact of raw materials sticking to the inner wall of the hopper on the measurement of other raw materials, and ensuring the accuracy of slag powder raw material batching.

[0005] This utility model is achieved through the following technical solution:

[0006] A batching device for slag powder processing includes a mixing mechanism. Multiple weighing mechanisms arranged in a circumferential array are disposed on the outer side of the mixing mechanism. The mixing mechanism includes a hopper, with a top plate connected to its upper end. Multiple feed pipes arranged in a circumferential array are connected above the top plate. A support shaft is disposed inside the hopper, and multiple stirring rods arranged in a circumferential array are disposed on the outer side of the support shaft. A scraper is connected to the end of each stirring rod away from the support shaft. A bearing plate is connected to the outer side of the hopper, and multiple second limiting grooves arranged in a circumferential array are disposed on the outer side of the bearing plate. The weighing mechanism includes a hopper, with weighing sensors connected to both sides of the hopper. A U-shaped plate is connected below two of the weighing sensors. Two second and third support legs are symmetrically connected to the lower ends of the U-shaped plate, respectively. A counterweight is connected below the two third support legs, and multiple casters are connected to both sides of the lower part of the counterweight.

[0007] As a further feature of the above scheme, the lower ends of the silo and the hopper are respectively connected to a first discharge pipe and a second discharge pipe. One end of the first discharge pipe and the second discharge pipe are respectively connected to a first valve and a second valve to facilitate the control of the opening and closing of the first discharge pipe and the second discharge pipe. An arc-shaped plate is provided on one side of the upper end of the feed pipe. The arc-shaped plate is slidably engaged with one side of the second discharge pipe. The second discharge pipe and the feed pipe are concentrically arranged to avoid the positional conflict between the arc-shaped plate and the feed pipe and the second discharge pipe, ensuring that the feed pipe can move smoothly downward after the slag powder raw material is put into the hopper.

[0008] As a further feature of the above solution, the upper end of the feed pipe is detachably connected to a cap, which can block the idle feed pipe and prevent impurities from entering the hopper.

[0009] As a further feature of the above solution, each of the four lower corners of the bearing plate is connected to a first support leg, which can provide stable support for the hopper and its connecting components. The top plate is provided with a plurality of first limiting grooves arranged in a circumferential array. The second and third support legs slide in cooperation with the first and second limiting grooves respectively, which facilitates the alignment of the multiple weighing mechanisms with the multiple feed pipes. The side of the third support leg away from the second support leg is connected to a handrail, which is convenient for the user to grip when adjusting the position of the weighing mechanism.

[0010] As a further feature of the above scheme, the upper end of the support shaft passes through the middle of the top plate and is rotatably connected to the top plate, which can ensure the smooth rotation of the support shaft. The upper end of the support shaft is connected to a motor, which can provide power for the rotation of the support shaft, stirring rod and scraper. The outer side of the motor is connected to the top plate through a base, which can provide stable support for the motor.

[0011] As a further feature of the above scheme, a controller is provided on one side of the mixing mechanism to facilitate the control of the operation of relevant components in the device.

[0012] In this utility model, at least one of the multiple universal wheels in the same weighing mechanism is a universal brake wheel.

[0013] The present invention has the following beneficial effects during use:

[0014] The combination of the support shaft, stirring rod and motor in the mixing mechanism can drive the support shaft and stirring rod to rotate, mix the slag powder raw materials in the silo evenly and then discharge them through the first discharge pipe. No additional mixing equipment is needed, saving the cost of slag powder processing equipment.

[0015] The combination of multiple feed pipes and weighing sensors allows for the selection of an appropriate number of weighing sensors based on the type of slag powder raw material. This avoids multiple raw materials sharing a single hopper, reduces the impact of raw materials sticking to the inner wall of the hopper on the metering of other raw materials, and ensures the accuracy of slag powder raw material batching. The second and third support legs are aligned with the first and second limiting grooves, respectively, which enables the second discharge pipe to be aligned with the feed pipe.

[0016] The use of counterweights can prevent the weighing mechanism from being unbalanced, thus keeping it stable during the weighing of slag powder raw materials. The use of multiple casters makes it easy to adjust the position of the weighing mechanism, saving users the effort of moving the weighing mechanism. Attached Figure Description

Detailed Implementation

[0025] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-6 This application will be described in detail with reference to the embodiments.

[0027] This embodiment discloses a batching device for slag powder processing, including a mixing mechanism 1. Multiple weighing mechanisms 2 arranged in a circumferential array are disposed on the outer side of the mixing mechanism 1. The mixing mechanism 1 includes a hopper 11, with a top plate 12 connected to the upper end of the hopper 11. Multiple feed pipes 121 arranged in a circumferential array are connected above the top plate 12. A support shaft 13 is disposed inside the hopper 11, and multiple stirring rods 14 arranged in a circumferential array are disposed on the outer side of the support shaft 13. A scraper 141 is connected to the end of each stirring rod 14 away from the support shaft 13. The outer side of the material bin 11 is connected to a support plate 16. The outer side of the support plate 16 is provided with a plurality of second limiting grooves 161 arranged in a circumferential array. The weighing mechanism 2 includes a hopper 21. Weighing sensors 22 are connected to both sides of the hopper 21. A U-shaped plate 23 is connected below the two weighing sensors 22. Two second support legs 24 and a third support leg 25 are symmetrically connected to the lower ends of the U-shaped plate 23. A counterweight 27 is connected below the two third support legs 25. A plurality of casters 28 are connected to both sides of the lower part of the counterweight 27.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the lower ends of the hopper 11 and the hopper 21 are respectively connected to a first discharge pipe 111 and a second discharge pipe 211. One end of the first discharge pipe 111 and the second discharge pipe 211 are respectively connected to a first valve 112 and a second valve 212 to facilitate the control of the opening and closing of the first discharge pipe 111 and the second discharge pipe 211. An arc plate 122 is provided on one side of the upper end of the feed pipe 121. The arc plate 122 slides with one side of the second discharge pipe 211. The second discharge pipe 211 and the feed pipe 121 are concentrically arranged to avoid the position of the arc plate 122 and the feed pipe 121 from conflicting with the second discharge pipe 211, ensuring that the feed pipe 121 can move smoothly downward after the slag powder raw material is put into the hopper 21.

[0029] like Figure 1 and Figure 3 As shown, the upper end of the feed pipe 121 is detachably connected to a cap 123, which can block the idle feed pipe 121 and prevent impurities from entering the hopper 11.

[0030] like Figure 1 , Figure 5 and Figure 6As shown, the four lower corners of the bearing plate 16 are each connected to a first support leg 17, which can provide stable support for the hopper 11 and its connecting parts. The top plate 12 is provided with a plurality of first limiting grooves 124 arranged in a circumferential array. The second support leg 24 and the third support leg 25 are respectively slidably engaged with the first limiting groove 124 and the second limiting groove 161, so as to facilitate the alignment of the plurality of weighing mechanisms 2 with the plurality of feed pipes 121. The side of the third support leg 25 away from the second support leg 24 is connected to a handrail 26, which is convenient for the user to grip when adjusting the position of the weighing mechanism 2.

[0031] like Figure 2 and Figure 4 As shown, the upper end of the support shaft 13 passes through the middle of the top plate 12 and is rotatably connected to the top plate 12, which can ensure that the support shaft 13 rotates smoothly. The upper end of the support shaft 13 is connected to a motor 15, which can provide power for the rotation of the support shaft 13, the stirring rod 14 and the scraper 141. The outer side of the motor 15 is connected to the top plate 12 through the base 151, which can provide stable support for the motor 15.

[0032] like Figure 1 As shown, a controller 3 is provided on one side of the mixing mechanism 1 to facilitate the control of the operation of the relevant components in the device.

[0033] The batching device for slag powder processing disclosed in this embodiment connects the original receiving device to the first discharge pipe 111 before use. A suitable number of weighing mechanisms 2 are determined according to the type of slag powder raw material. Based on the number of weighing sensors 22, the caps 123 at the top of a suitable number of feed pipes 121 are removed. The brake wheels of the casters 28 in the same weighing mechanism 2 are released. The weighing mechanism 2 is moved to one side of the support plate 16 by grasping the handle 26. The two third support legs 25 are respectively connected to the two second limiters on one side of the support plate 16. Align the groove 161, push the weighing mechanism 2 toward the bearing plate 16 until the side of the third support leg 25 near the bottom of the second limiting groove 161 is in contact with the bottom of the second limiting groove 161. Depress the brake wheel to fix the weighing mechanism 2. At this time, the second support leg 24 is in contact with the side of the first limiting groove 124 away from the third support leg 25. Align the second discharge pipe 211 with the feed pipe 121. Connect the weighing sensor 22 and the second valve 212 to the controller 3. Repeat the above operation to adjust the position of the remaining weighing mechanism 2.

[0034] The controller 3 is used to tare the weighing sensors 22 in multiple weighing mechanisms 2 in sequence. After the tare process is completed, different raw materials can be put into multiple different hoppers 21 in sequence. The data of the weighing sensors 22 is observed on the controller 3. When the required weight for the proportion is reached, the addition of raw materials to the hoppers 21 is stopped, the second valve 212 is opened, and the weighed raw materials are discharged into the feed bin 11 through the second discharge pipe 211 and the feed pipe 121. When all the raw materials in all hoppers 21 are discharged, the controller 3 is used to start the motor 15, so that the motor 15 drives the agitator through the support shaft 13. The mixing rod 14 and scraper 141 rotate to mix the raw materials in the hopper 11 evenly. Then, the controller 3 can open the first valve 112 to discharge the mixed raw materials through the first discharge pipe 111 into the original receiving device. During the rotation of the scraper 141, the raw materials can be prevented from sticking to the inner wall of the hopper 11. During the mixing process, different raw materials can be put into the corresponding hopper 21 for weighing again so that after the mixed raw materials in the hopper 11 are discharged, the first valve 112 can be closed and new raw materials can be injected into the hopper 11 in a timely manner to improve the efficiency of raw material batching and mixing.

[0035] The components disclosed in this utility model for a batching device for slag powder processing, including controller 3, hopper 11, first valve 112, feed pipe 121, cover 123, support shaft 13, stirring rod 14, motor 15, bearing plate 16, first support leg 17, hopper 21, second valve 212, weighing sensor 22, U-shaped plate 23, second support leg 24, third support leg 25; 27, handrail 26; 28, counterweight 27, and caster wheel 28, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
