Technical Field

[0001] The utility model relates to the technical field of mineral powder density detection devices, in particular to a simple mineral powder density detection device. Background Art

[0002] Mineral powder is a high-fine powder made from water-quenched blast furnace slag that has been dried, ground and processed. It is a high-quality road concrete admixture and cement mixture. Mineral powder will be affected by the processing technology, resulting in differences in density, and the sealing of mineral powder will also affect the quality of concrete. Therefore, when mineral powder is needed, the density of the mineral powder needs to be tested.

[0003] In the prior art, when testing the density of mineral powder, it is usually necessary to inject anhydrous kerosene and mineral powder into a Lee's pycnometer in sequence, and then immerse the Lee's pycnometer in a constant temperature water tank for multiple times to obtain an accurate value of the mineral powder density.

[0004] However, when it is necessary to immerse the Lee's density bottle in a constant temperature water tank, the Lee's density bottle needs to be removed from the detection device and then placed in the constant temperature water tank. After the detection is completed, the detection device needs to be placed on the detection device again, which makes the entire operation process very cumbersome and inconvenient to quickly immerse the Lee's density bottle in the constant temperature water tank. Utility Model Content

[0005] The utility model aims to provide a simple mineral powder density detection device to solve the problem in the above background technology that the currently used mineral powder density detection device is not convenient to quickly immerse the Lee's pycnometer in a constant temperature water tank.

[0007] Preferably, one side of the support frame is connected to a support plate via a mounting block, and a telescopic plate is mounted in the middle of the support plate via a groove.

[0008] Preferably, a threaded sleeve is installed on one side of the support plate, a bidirectional threaded rod is connected through the middle of the threaded sleeve, one end of the bidirectional threaded rod is connected to a bevel gear set, and the top of the bevel gear set is connected to a drive shaft that passes through the support plate.

[0009] Preferably, a transmission motor is connected to the top of the driving shaft, and a constant temperature water tank is provided on the top of the base.

[0010] Preferably, an insert block is installed on one side of the installation block, and clamp blocks are penetrated and connected on both sides of the insert block.

[0011] Preferably, a movable spring is installed between the clamping block and the groove of the inserting block, and a rotating block is provided on one side of the clamping block.

[0012] Preferably, one side of the rotating block is connected to a pressure rod via a rotating shaft, the top of the pressure rod is connected to a push rod penetrating the insert block and the mounting block, and a telescopic spring is installed between the push rod and the groove of the insert block.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] When the simple mineral powder density detection device proposed by the utility model is in use, the transmission motor on the support plate can be started according to the detection requirements, and the transmission motor will rotate the bidirectional threaded rod through the cooperation of the driving shaft and the bevel gear set.

At the same time, when the constant temperature water tank is not needed, the telescopic plate can also be used to support the Lee's specific gravity bottle, so as to facilitate the detection of mineral powder density.

Embodiment 2

[0023] On the basis of Example 1, in order to place the Lee's specific gravity bottle 8 in the constant temperature water tank 17, the transmission motor 16 on the top of the support plate 10 can be started, and the output end of the transmission motor 16 is connected to the drive shaft 15 that passes through the support plate 10, and the drive shaft 15 is connected to the bidirectional threaded rod 13 through a bevel gear set 14. The bevel gear set 14 is composed of two mutually meshing bevel gear sets 14 connected, one bevel gear is connected to the drive shaft 15, and the other bevel gear is connected to the bidirectional threaded rod 13. At this time, the bevel gear set 14 will drive the bidirectional threaded rod 13 to rotate, and the outer side of the bidirectional threaded rod 13 is sleeved with a threaded sleeve 12, and the rotation of the bidirectional threaded rod 13 will drive the threaded sleeve 12 to slide, and the threaded sleeve 12 is connected to the telescopic plate 11. At this time, The two sets of telescopic plates 11 will be driven into the grooves of the support plate 10. While sliding, the telescopic plates 11 will slide along the grooves of the support plate 10 through the slider on the other side, so that the telescopic plates 11 are more stable during the sliding process. Without the support of the telescopic plates 11 on the Lee specific gravity bottle 8, the drive motor 4 can be started.

At this time, the top rod 23 will pull the pressure rod 22 to rotate through the rotating shaft. When the pressure rod 22 rotates, it will rotate by rotating and pulling the rotating block 21, so that the two groups of rotating blocks 21 rotate close to each other. When the rotating block 21 rotates, there is no squeezing of the block 19 on one side, and then the block 19 will be retracted into the groove of the plug block 18 by the movable spring 20. When the plug block 18 is inserted into the groove at the top of the base 1, the top rod 23 is released, and the top rod 23 is reset by the telescopic spring 24, so that the top rod 23 moves in the opposite direction, and the rotating block 21 is rotated in the opposite direction by the pressure rod 22, and the rotating block 21 will squeeze the block 19 on one side, so that the block 19 moves out of the groove of the plug block 18 and penetrates the plug block 18 and is inserted into the groove of the base 1, and the mounting block 2 is installed at the bottom of the support frame 3. At this time, the support frame 3 can be quickly installed on the top of the base 1. Similarly, the mounting block 2 on one side of the support plate 10 is connected to the support plate 10, and the plug block 18 is inserted into the groove of the support frame 3.

[0026] In actual use, the simple mineral powder density detection device is used to place the Lee's pycnometer 8 on the middle telescopic plate 11 of the support plate 10, and then the telescopic frame 6 is adjusted so that the clamping block 7 can fix the Lee's pycnometer 8, and the position of the feed hopper 9 is adjusted so that the feed hopper 9 is aligned with the opening position of the Lee's pycnometer 8, and then anhydrous kerosene and a magnetic rod can be injected into the Lee's pycnometer 8 in sequence through the feed hopper 9, and according to the detection requirements, the telescopic frame 6 and the clamping block 7 drive the Lee's pycnometer 8 to move to the constant temperature water tank 17 by the cooperation of the driving motor 4, the screw rod 5 and the screw sleeve, and the value is recorded through the display panel on one side of the base 1, and then the mineral powder is injected into the Lee's pycnometer 8, and then the Lee's pycnometer 8 is moved to the constant temperature water tank 17 again, and the value is read again after standing. At this time, the density value of the mineral powder density can be obtained. This is a prior art and will not be elaborated on here.
