Description

Technical Field

[0001] The utility model relates to the technical field of regenerated fillers, in particular to a regenerated filler density detection device. Background Art

[0002] Urban construction will generate a large amount of construction waste, such as broken bricks, concrete blocks, etc. These construction wastes have occupied land resources for a long time and have not been properly handled. If the construction waste is broken into small stones using recycling technology and used as recycled fillers to replace gravel as cement fillers or railway and highway roadbed fillers, it will be environmentally friendly and energy-saving, and benefit the country and the people.

[0003] Recycled fillers such as masonry and concrete blocks need to be tested for density after crushing. The density of recycled fillers is related to the mixing ratio and crushing particle size of masonry and concrete blocks. To test the density, the volume of the recycled filler must be measured first. The commonly used volume measurement method is the water filling method. Unlike gravel, masonry and concrete blocks have greater water absorption, resulting in the measured volume being greater than the actual volume. Therefore, it is necessary to design a density detection device dedicated to recycled fillers. Utility Model Content

[0009] The lifting mechanism is used for lifting the hanging basket, and an electronic scale is arranged on the hook of the lifting mechanism.

[0010] To further improve the technical solution, an annular trough is provided at the bottom of the water tank along the circumferential direction; the drain pipe is arranged at the bottom of the trough, and a valve is installed on the drain pipe.

[0011] To further improve the technical solution, a bracket is provided in the middle part of the bottom of the water tank, and the water tank is placed on the seat scale through the bracket.

[0012] To further improve the technical solution, after the hanging basket is placed in the water tank, the height of the overflow pipe is greater than the height of the hanging basket.

[0013] To further improve the technical solution, the lifting mechanism is mainly composed of a column, a rotating cross arm, a fixed pulley and a winch, wherein the winch is fixed at one end of the rotating cross arm and the fixed pulley is fixed at the other end of the rotating cross arm.

[0014] To further improve the technical solution, a rotating hand push rod is fixed to one end of the rotating cross arm close to the winch.

[0015] After implementing the above technical solution, compared with the background technology, the beneficial effects produced by the utility model are:

[0016] The regenerated filler density detection device can eliminate the interference of the water absorption of the regenerated filler, and the actual density of the regenerated filler can be obtained by weighing it four times with a table scale and an electronic scale hook.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0024] As attached Figure 1 As shown, a regenerated filler density detection device includes a seat scale 1, a water tank 3, a hanging basket 4 and a lifting mechanism 5. Its structure and function are described in detail below.

[0025] Refer to the attached Figure 2 The water tank 3 is placed on the seat scale 1, and the water tank 3 has a water inlet pipe 31, a drain pipe 33 and an overflow pipe 32. In this embodiment, the water tank 3 is a square water tank 3, with a bottom surface of 1.4*1.4 meters and a height of 1 meter.

[0026] In order to drain the water in the water tank 3, an annular trough is provided along the circumference at the bottom of the water tank 3. A drain pipe 33 is provided at the bottom of the trough, and a valve 34 is installed on the drain pipe 33. A bracket 2 is provided at the middle part of the bottom of the water tank 3, and the water tank 3 is placed on the seat scale 1 through the bracket 2.

[0027] The hanging basket 4 is used to hold the recycled filler. In this embodiment, the hanging basket 4 is a square hanging basket 4, the bottom surface of the hanging basket 4 is 1.0*1.0 meters, and the height is 0.7 meters. The hanging basket 4 can be placed in the water tank 3, and a handle is provided on the upper part of the hanging basket 4, and a sieve hole is provided on the bottom of the hanging basket 4. The volume of the hanging basket 4 is designed to be so large because a sufficient amount of recycled filler samples need to be extracted.

[0028] It is worth noting that after the hanging basket 4 is placed in the water tank 3 , the height of the overflow pipe 32 is greater than the height of the hanging basket 4 .

[0029] Refer to the attached Figure 3Since the hanging basket 4 and the recycled filler in the hanging basket 4 are very heavy, a lifting mechanism 5 is used. A hook is provided on the lifting mechanism 5, and the hook is used to lift the hanging basket 4. An electronic scale is provided on the hook. Currently, there is a hook with an electronic scale on the market, which can weigh the lifted object while lifting. This electronic scale hook 55 is used in the utility model.

[0030] In this embodiment, the lifting mechanism 5 is a rotating lifting mechanism, which is mainly composed of a column 51, a rotating cross arm 52, a fixed pulley 54 and a winch 53. The winch 53 is fixed to one end of the rotating cross arm 52, the fixed pulley 54 is fixed to the other end of the rotating cross arm 52, and a rotating hand push rod 56 is fixed to one end of the rotating cross arm 52 close to the winch 53.

[0031] Measurement process of recycled filler density:

[0032] Refer to the attached Figure 4 . First, the hanging basket 4 and the regenerated filler in the hanging basket 4 are weighed by the electronic scale hook 55, and the weight is G0. The net weight of the regenerated filler is G (G0 minus the weight of the hanging basket 4). Then the hanging basket 4 is hung in the water tank 3, and water 6 is injected into the water tank 3 through the water inlet pipe 31 until water flows out of the overflow pipe 32, and then the water inlet pipe 31 is closed. At this time, the total weight G1 is weighed by the seat scale 1, so the total injected weight of the water 6 in the water tank 3 is G2=G1-G0.

[0033] Refer to the attached Figure 5 The hanging basket 4 is suspended in the air by the electronic scale hook 55, so that the water in the hanging basket 4 is drained into the water tank 3 through the sieve holes until no water is drained. At this time, the weight of the water 6 in the water tank 3 is weighed by the seat scale 1, which is calculated as G3 (the weight minus the weight of the water tank 3 and the bracket 2), and then the hanging basket 4 and the recycled filler in the hanging basket 4 are weighed by the electronic scale hook 55, which is calculated as G4. Since the recycled filler is water-absorbent, G4 is greater than G0.

[0034] Then, assuming that the actual drainage weight of the recycled filler is G5, we have G5=G2-G3-(G4-G0), and substituting G2=G1-G0, we get G5=G1-G3-G4.

[0035] Then convert the actual drainage weight G5 into the actual drainage volume to obtain the volume V of the regenerated filler. Finally, the density of the regenerated filler is calculated using the density formula p=G / V.

[0036] Refer to the attached Figure 6 After weighing, the basket 4 is rotated to the other side by rotating the push rod 56, and the basket 4 is placed on the ground by the winch 53. Then the valve 34 is opened, and the water in the water tank 3 is drained through the drain pipe 33.

[0037] As can be seen from the above, the present regenerated filler density detection device can eliminate the interference of the water absorption of the regenerated filler, and the actual density of the regenerated filler can be obtained by four weighings of the table scale 1 and the electronic scale hook 55. In addition, the present regenerated filler density detection device also reduces the labor intensity with the help of the lifting mechanism 5, greatly improving the test efficiency.

[0038] Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the protection scope of the present invention is defined by the attached claims and their equivalents.
