[0002] Mineral powder is a high-fineness, high-activity powder obtained by drying, grinding and other processes with water-quenched blast furnace slag. Since mineral powder can effectively improve the compressive strength of concrete and reduce the cost of concrete during the preparation of high-performance concrete, it is widely used in the construction industry.
[0003] Since the size of mineral powder particles varies, when using mineral powder for concrete preparation, workers usually add a filtering structure inside the feeding device to filter and intercept the mineral powder with larger particle size. However, the setting of the filtering structure in the traditional feeding device will reduce the feeding speed of the mineral powder, and it is also easy to cause blockage inside the device, thereby affecting the feeding efficiency of the mineral powder and further affecting the preparation progress of the concrete. Utility Model Content

[0008] Furthermore, two arc-shaped inner walls are provided inside the filter cavity, and the two arc-shaped inner walls are respectively located on both sides of the filter plate, the arc center of each arc-shaped inner wall coincides with the rotation axis of the filter plate, and the side wall of the filter plate contacts the arc-shaped inner wall.
[0009] Furthermore, the cross-sectional areas of the first channel and the second channel are equal to the cross-sectional area of the discharge cavity, and the cross-sectional area of the feed cavity is smaller than the sum of the cross-sectional areas of the first channel and the second channel.
[0010] Furthermore, a cleaning port is provided on the side wall of the discharge box, the cleaning port is communicated with the filter cavity, and a reversible sealing plate is provided in the cleaning port.

[0013] The utility model discloses a mineral powder feeding device, in which a filter plate is provided inside the filter cavity, and a first channel and a second channel are formed inside the receiving cavity through an isolation plate. After the screw conveyor conveys the mineral powder to the inside of the feeding box, the filter plate can block the large particles in the mineral powder and allow small particles of mineral powder to enter the first channel and the second channel. Secondly, the device is provided with a rotatable baffle under the isolation plate. Since the baffle can block the first channel or the second channel, when feeding, the staff can regularly drive the baffle to rotate, so that the first channel and the second channel alternately enter the blocking state. In this way, the channel that enters the blocking state will accumulate small particles of mineral powder, and the channel that does not enter the blocking state can guide the small particles of mineral powder to the inside of the discharge cavity, thereby ensuring that the device continuously provides mineral powder supply to subsequent equipment. In addition, since the filter plate in the device can rotate, when any channel enters the blocked state, the filter plate can be tilted toward the blocked channel by rotation, so that the filtered small particles of mineral powder can quickly enter the blocked channel, accelerating the accumulation speed of small particles of mineral powder. At the same time, the rotation process can also make the mineral powder above the filter plate move relative to the filter plate, thereby improving the filtration efficiency and reducing the probability of filter plate clogging.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.
[0026] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0027] A mineral powder feeding device, the structure of which can be Figure 1-Figure 6 As shown in the figure, in this embodiment, the mineral powder feeding device includes: a feeding box 1, a screw conveyor 2, a filter plate 3 and a baffle 4, wherein the screw conveyor 2 is used to convey the mineral powder into the feeding box 1, and the filter plate 3 and the baffle 4 are both rotatably arranged in the feeding box 1. When working, the mineral powder can be filtered inside the feeding box 1, and the feeding process of the mineral powder can be controlled, so that the subsequent equipment can obtain continuous and stable mineral powder transportation.
[0028] Specifically, Figure 2 and Figure 3 As shown, the lower material box 1 is provided with a feed cavity 11, a filter cavity 12, a receiving cavity and a discharge cavity 14 which are connected in sequence from top to bottom, and a discharge port connected to the discharge cavity 14 is provided on the bottom surface of the lower material box 1. The filter plate 3 is rotatably arranged inside the filter cavity 12, and a plurality of filter holes 31 are provided on the filter plate 3. An isolation plate 13 is provided inside the receiving cavity, and a first channel 131 and a second channel 132 are formed on both sides of the isolation plate 13, respectively. The baffle plate 4 is rotatably arranged at the bottom of the isolation plate 13, and the baffle plate 4 is used to block the bottom end of the first channel 131 or the second channel 132. A feed port 21 is provided on the screw conveyor 2, and the discharge port of the screw conveyor 2 is connected to the feed cavity 11.
[0029] During operation, the staff can put the mineral powder into the screw conveyor 2 along the feed port 21, and then convey the mineral powder into the feed cavity 11 by means of the screw conveyor 2. Subsequently, the mineral powder in the feed cavity 11 moves downward under the action of gravity and is blocked by the filter plate 3. The filter plate 3 can filter the mineral powder so that large particles of mineral powder stay above the filter plate 3, and small particles of mineral powder enter the first channel 131 and the second channel 132 along the filter hole 31.
[0030] Since a rotatable baffle plate 4 is provided below the isolation plate 13, the staff can adjust the state of the baffle plate 4 by rotating it so that the baffle plate 4 blocks the bottom end of the first channel 131 or the second channel 132 according to actual working needs. Figure 4 As shown, at this time, the first channel 131 enters the blocked state, while the second channel 132 does not enter the blocked state. Therefore, the small particles of mineral powder in the first channel 131 will be accumulated, while the small particles of mineral powder in the second channel 132 will enter the discharge cavity 14 and eventually leave the device through the discharge port. Accordingly, after the small particles of mineral powder in the first channel 131 have accumulated for a period of time, the staff can drive the baffle 4 to rotate so that the device switches to the state as shown in FIG. Figure 5 At this time, the second channel 132 will enter a blocked state, thereby accumulating small-particle mineral powder, and the small-particle mineral powder accumulated in the first channel 131 will enter the discharge cavity 14 and eventually leave the device through the discharge port.
[0031] Compared with the traditional feeding device, since the present device can make the first channel 131 and the second channel 132 alternately enter the blocking state, it can provide sufficient time for the filtering of the mineral powder, while ensuring that the subsequent equipment obtains a continuous supply of mineral powder, so that the configuration of concrete has a higher efficiency.
[0032] Optionally, in order to facilitate the control of the amount of mineral powder processed inside the discharge box 1, in this embodiment, the cross-sectional areas of the first channel 131 and the second channel 132 should be equal to the cross-sectional area of the discharge cavity 14, and the cross-sectional area of the feed cavity 11 should be smaller than the sum of the cross-sectional areas of the first channel 131 and the second channel 132. Since the cross-sectional area of the feed cavity 11 is smaller than the sum of the cross-sectional areas of the first channel 131 and the second channel 132, it is possible to avoid excessive mineral powder entering the inside of the discharge box 1 per unit time. Accordingly, since the cross-sectional areas of the first channel 131 and the second channel 132 are equal to the cross-sectional area of the discharge cavity 14, when any one of the channels is in an unblocked state, the inside of the discharge cavity 14 can obtain sufficient mineral powder supply, thereby increasing the mineral powder output of the device.
[0033] In addition, in order to facilitate the filtered small-particle mineral powder to enter the discharge cavity 14 smoothly, a guide slope 141 can be provided between the discharge cavity 14 and the receiving cavity. By providing the guide slope 141, the small-particle mineral powder can be gathered, thereby avoiding the mineral powder residue in the receiving cavity.
[0034] In order to conveniently drive the filter plate 3 and the baffle plate 4 to rotate, the device may further include a driving assembly. Specifically, the driving assembly may include: an equipment box 51, a driving motor 52, a first gear 53 and a second gear 54, wherein the equipment box 51 is arranged on the side wall of the material box 1, the first gear 53 and the second gear 54 are both arranged inside the equipment box 51, and the first gear 53 is connected to the output shaft of the driving motor 52, and the second gear 54 is meshed with the first gear 53. Figure 6 As shown, in this embodiment, a first connecting shaft 41 should be provided on the baffle plate 4, and a second connecting shaft 32 should be provided on the filter plate 3. During assembly, the first connecting shaft 41 should be connected to the first gear 53, and the second connecting shaft 32 should be connected to the second gear 54.
[0035] Since the first gear 53 and the second gear 54 are in meshing state, when the driving motor 52 is started, the baffle plate 4 and the filter plate 3 will rotate in opposite directions. Figure 4 and Figure 5 As shown, when the baffle 4 blocks the first channel 131 due to rotation, the filter plate 3 will be tilted toward the first channel 131 due to rotation. Correspondingly, when the baffle 4 blocks the second channel 132 due to rotation, the filter plate 3 will be tilted toward the second channel 132 due to rotation.
[0036] The rotation of the filter plate 3 can generate relative movement between the mineral powder and the filter plate 3, thereby improving the filtering efficiency of the mineral powder and preventing the mineral powder from accumulating on the filter plate 3. At the same time, the inclination of the filter plate 3 toward the blocked channel can enable the small particles of mineral powder that have been filtered to quickly enter the blocked channel, thereby accelerating the storage efficiency of the mineral powder and facilitating the staff to switch the blocking of the two channels at a faster frequency, thereby increasing the mineral powder output of the device.
[0037] Optionally, in order to prevent the mineral powder on the top of the filter plate 3 from falling down along the joint gap during the rotation of the filter plate 3, the present embodiment may be provided with two arc-shaped inner walls 121 inside the filter cavity 12. Specifically, the two arc-shaped inner walls 121 should be located on both sides of the filter plate 3, respectively, the arc center of each arc-shaped inner wall 121 should coincide with the rotation axis of the filter plate 3, and the side wall of the filter plate 3 is in contact with the arc-shaped inner wall 121.
[0038] As an optional implementation of this embodiment, in order to facilitate the cleaning of large-particle mineral powder above the filter plate 3 when the device is shut down, a cleaning port (not shown in the figure) connected to the filter cavity 12 may be provided on the side wall of the feed box 1, and a reversible sealing plate (not shown in the figure) may be provided in the cleaning port. When shutting down for maintenance, the staff can open the sealing plate and clean the inside of the filter cavity through the cleaning port, thereby preventing large-particle mineral powder from occupying the internal space of the filter cavity 12.
[0039] The effects of the above scheme are described below:
[0040] This embodiment provides a mineral powder feeding device, which can block large particles in the mineral powder through the filter plate and allow small particles of mineral powder to enter the first channel and the second channel. Secondly, the device can switch the blocking state of the two channels by rotating the baffle plate, so that the device can continuously provide mineral powder to the subsequent equipment. In addition, the device can also generate relative movement between the mineral powder and the filter plate through the rotation of the filter plate, and can make the filter plate tilt toward the channel in the blocked state, thereby accelerating the mineral powder processing speed.
[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
