Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a concrete recycled material production line. Background Art

[0002] Recycled concrete materials refer to materials that are produced by recycling and treating discarded concrete or other construction waste, and then reprocessing them as raw materials to produce new concrete products. The equipment used when recycled concrete materials are used in the processing of cement is the recycled material production line, which is a combination of equipment and processes used to treat and process the recycled materials and finally produce them into concrete products.

[0003] Among them, when mixing different raw materials, the processed recycled materials are mixed with raw materials such as cement, aggregates, admixtures, etc. to produce concrete products. However, the stirring shaft can only stir the recycled materials and other raw materials horizontally. Materials at different heights are difficult to mix, resulting in more time required for stirring and mixing, and the mixing is insufficient. For this reason, we propose a concrete recycled material production line to solve the existing problems. Summary of the invention

[0004] The purpose of the present invention is to propose a concrete recycled material production line in view of the problems existing in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a concrete recycled material production line, comprising a motor, a top cover, a barrel, a mounting box, a stirring shaft and a rotating shaft, the barrel body is provided with a top cover at the upper end, the top cover is provided with a motor at the upper end, the motor output end is provided with a rotating shaft rotatably installed inside the top cover, the outer wall of the rotating shaft is sleeved with equidistantly distributed conical toothed discs, the outer side of the conical toothed disc is sleeved with a mounting box, the installation box is embedded with bearings distributed in a circular array, the bearing is rotatably inserted with a stirring shaft, the outer wall of the stirring shaft is provided with a plurality of groups of stirring rods distributed in a circular array, and one end of the stirring shaft is provided with a conical gear meshing with the conical toothed disc.

[0006] Preferably, a feed port is provided inside the upper end of the top cover, and a sealing cover is provided inside the upper end of the feed port. Recycled concrete and other auxiliary raw materials are input into the barrel body through the feed port, and the feed port is opened and closed by the sealing cover.

[0007] Preferably, the outer wall of the top cover is sleeved with an annular side plate, and the outer wall of the barrel body is sleeved with a bracket. The bracket supports the outer wall of the barrel body so that the barrel body is suspended on the ground.

[0008] Preferably, the bracket is provided with symmetrically distributed hydraulic rods, and the telescopic ends of the hydraulic rods are connected to the lower ends of the side plates. When the hydraulic rods are in operation, the squeezing force of the telescopic ends acts on the top cover through the side plates, thereby driving the top cover to move longitudinally.

[0009] Preferably, the upper end of the installation box is provided with a conical surface, which is distributed in an annular shape. During the process of mixing and discharging the recycled concrete and other raw materials, the conical surface helps the flow of the mixture to avoid the accumulation of the mixture on the upper end of the installation box.

[0010] Preferably, a discharge pipe is provided at the lower end of the barrel, a control valve is provided inside the discharge pipe, and a funnel-shaped guide surface is provided on the inner wall of the lower end of the barrel. The mixed material is discharged through the discharge pipe, and the control valve controls the opening and closing of the discharge pipe. When discharging, the guide surface guides the mixed material to help the flow of the mixed material.

[0011] Preferably, the top cover is mounted on the opposite end of the barrel body, and a sealing gasket is arranged on the upper end of the barrel body in an annular shape. After the top cover is mounted on the barrel body, the fastener is lifted, and the sealing of the top cover and the barrel body is improved by the sealing gasket.

[0012] Preferably, a pump casing is fixed above the top cover, a transmission shaft rotatably mounted with the pump casing is rotatably mounted on the upper end of the top cover, and an impeller rotatably mounted inside the pump casing is sleeved on the outer wall of the transmission shaft. When the transmission shaft drives the impeller to rotate inside the pump casing, it cooperates with the pump casing suction end to generate suction force inside the pump casing.

[0013] Preferably, a side box penetrating the barrel body is installed at one end of the barrel body, a support net is provided at the connection between the side box and the barrel body, and support rods equidistantly distributed and fixed inside the side box are provided on one side of the support net, a heating plate is provided inside the side box, and the output end of the pump housing is connected to the side box through a hose. The support rods support one side of the support rods to prevent the mixed material inside the barrel body from squeezing the support net, improve the strength of the support net, and ensure that the gas passes through the support net.

[0014] Preferably, the outer wall of the rotating shaft is sleeved with a gear 1, the outer wall of the transmission shaft is sleeved with a gear 2 which has a radius smaller than that of the gear 1 and meshes with the gear 1, one end of the transmission shaft is provided with a mounting plate, and one end of the mounting plate is provided with scrapers distributed at equal intervals. When the gear 1 rotates, it meshes with the gear 2, and the rotational force of the rotating shaft acts on the transmission shaft to accelerate the rotation.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The recycled concrete material of the present invention is transported to the inside of a barrel body. During the process of mixing with other raw materials, a motor drives a rotating shaft to rotate, driving a stirring shaft to stir the recycled concrete material and other raw materials horizontally. Due to the meshing relationship between the conical toothed disc and the conical gear, the stirring shaft rotating horizontally is pushed to rotate vertically, driving a stirring rod to mix the recycled concrete material and other raw materials vertically, thereby realizing efficient mixing of the recycled concrete material and other raw materials. Since the raw materials are efficiently mixed, the mixing time of the recycled concrete material and other raw materials is shortened. BRIEF DESCRIPTION OF THE DRAWINGS

The rotating shaft 13 drives the stirring shaft 8 to stir the recycled concrete material and other raw materials and additives, and stir and mix the recycled concrete material and other raw materials and additives horizontally for stirring and processing. At the same time, the rotating shaft 13 drives the conical toothed disc 14 to rotate, because the stirring shaft 8 is rotatably installed inside the installation box 7, and the conical toothed disc 14 is meshed with the conical gear 16. By pushing the conical gear 16, the stirring shaft 8 is driven to rotate longitudinally, so that the recycled concrete material and other raw materials and additives at different heights are stirred and processed, and the stirring effect of the recycled concrete material and other raw materials and additives is improved. Because the stirring effect of the recycled concrete material and other raw materials and additives is improved, the time required for sufficient stirring and mixing is shortened, and the efficiency of the stirring process of the recycled concrete material and other raw materials and additives is improved; The outer wall of the top cover 2 is sleeved with a ring-shaped side plate 11, and the outer wall of the barrel body 4 is sleeved with a bracket 5; The bracket 5 is provided with symmetrically distributed hydraulic rods 3, and the telescopic ends of the hydraulic rods 3 are connected to the lower ends of the side plates 11; A discharge pipe is provided at the lower end of the barrel body 4, a control valve is provided inside the discharge pipe, and a funnel-shaped flow guide surface is provided on the inner wall of the lower end of the barrel body 4; The top cover 2 is fitted with one end of the barrel body 4, and a sealing gasket is provided on the upper end of the barrel body 4 in an annular shape.

Example 3

[0022] It comprises a motor 1, a top cover 2, a barrel body 4, a mounting box 7, a stirring shaft 8 and a rotating shaft 13. The top cover 2 is arranged on the upper end of the barrel body 4, the motor 1 is arranged on the upper end of the top cover 2, the output end of the motor 1 is provided with a rotating shaft 13 rotatably mounted inside the top cover 2, the outer wall of the rotating shaft 13 is sleeved with equidistantly distributed conical toothed discs 14, the outer side of the conical toothed disc 14 is sleeved with a mounting box 7, the inside of the mounting box 7 is embedded with bearings 15 distributed in an annular array, the inside of the bearing 15 is rotatably plugged with the stirring shaft 8, the outer wall of the stirring shaft 8 is provided with a plurality of groups of stirring rods 9 distributed in an annular array, and one end of the stirring shaft 8 is provided with a conical gear 16 meshing with the conical toothed disc 14; A feed port 6 is provided inside the upper end of the top cover 2, and a sealing cover 12 is provided inside the upper end of the feed port 6; The upper end of the installation box 7 is provided with a conical surface 10, and the conical surface 10 is distributed in an annular shape; The recycled concrete material is input into the barrel body 4 through the feed port 6, and other raw materials or additives for cement processing are input into the barrel body 4 at the same time. The sealing cover 12 closes the feed port 6, and the motor 1 operates to drive the rotating shaft 13 to rotate. The rotating shaft 13 drives the stirring shaft 8 to stir the recycled concrete material and other raw materials and additives, and stir and mix the recycled concrete material and other raw materials and additives horizontally for stirring and processing. At the same time, the rotating shaft 13 drives the conical toothed disc 14 to rotate, because the stirring shaft 8 is rotatably installed inside the installation box 7, and the conical toothed disc 14 is meshed with the conical gear 16. By pushing the conical gear 16, the stirring shaft 8 is driven to rotate longitudinally, so that the recycled concrete material and other raw materials and additives at different heights are stirred and processed, and the stirring effect of the recycled concrete material and other raw materials and additives is improved. Because the stirring effect of the recycled concrete material and other raw materials and additives is improved, the time required for sufficient stirring and mixing is shortened, and the efficiency of the stirring process of the recycled concrete material and other raw materials and additives is improved; The outer wall of the top cover 2 is sleeved with a ring-shaped side plate 11, and the outer wall of the barrel body 4 is sleeved with a bracket 5; The bracket 5 is provided with symmetrically distributed hydraulic rods 3, and the telescopic ends of the hydraulic rods 3 are connected to the lower ends of the side plates 11; A discharge pipe is provided at the lower end of the barrel body 4, a control valve is provided inside the discharge pipe, and a funnel-shaped flow guide surface is provided on the inner wall of the lower end of the barrel body 4; The top cover 2 is fitted with one end of the barrel body 4, and a sealing gasket is provided on the upper end of the barrel body 4 in an annular shape. After the concrete recycled material and other raw materials and additives are mixed and processed, the valve controls the discharge pipe to open, and the mixed material is discharged through the discharge port. After the mixed material is discharged, the next process is carried out. The hydraulic rod 3 drives the side plate 11 to lift, and then drives the top plate to lift, so that the top plate is separated from the opening of the barrel body 4, and the mixing component enters the top of the barrel body 4. Because the mixing component is located outside, it is convenient to clean the mixing component and the inside of the barrel body 4, and it also provides convenience for the maintenance of the mixing component and the motor 1.

[0023] A pump casing 17 is fixed above the top cover 2, a transmission shaft 25 rotatably mounted on the upper end of the top cover 2 and rotatably mounted with the pump casing 17, and an impeller 24 rotatably mounted inside the pump casing 17 is sleeved on the outer wall of the transmission shaft 25; A side box 20 penetrating the barrel body 4 is installed at one end of the barrel body 4, a support net 23 is provided at the connection between the side box 20 and the barrel body 4, and support rods 22 equidistantly distributed and fixed inside the side box 20 are provided on one side of the support net 23, a heating plate 21 is provided inside the side box 20, and the output end of the pump housing 17 is connected to the side box 20 through a hose; The outer wall of the rotating shaft 13 is sleeved with a gear 1 26, the outer wall of the transmission shaft 25 is sleeved with a gear 2 27 with a radius smaller than that of the gear 1 26 and meshing with the gear 1 26, one end of the transmission shaft 25 is provided with a mounting plate 18, and one end of the mounting plate 18 is provided with equidistantly distributed scraping strips 19; In this embodiment, when the rotating shaft 13 rotates, the driving gear 1 26 rotates, and the gear 1 26 pushes the gear 2 27, thereby driving the transmission shaft 25 to rotate. When the transmission shaft 25 rotates, it drives the impeller 24 to rotate inside the pump housing 17, and generates a suction force inside the pump housing 17. The suction gas is transported to the inside of the side box 20 through the hose. The gas inside the side box 20 is heated and flows into the inside of the barrel body 4 through the support net 23. The pores of the support net 23 are smaller than the specifications of the mixture, so as to prevent the mixture from entering the side box 20 through the support net 23. At the same time, when the stirring shaft 8 rotates horizontally and vertically, the disk is driven to rotate synchronously. When the mounting disk 18 passes through the support net 23, it drives the scraper 19 to scrape one end of the support net 23 located inside the barrel body 4, and peels off the mixture adhered to the support net 23 to prevent the support net 23 from being blocked. The support net 23 is self-cleaning during use and is stable in use. The heated gas enters the barrel body 4 to dry and heat the mixture, and the moisture in the mixture is evaporated. It is worth mentioning that an exhaust port is provided inside the top cover 2. Because the material mixing effect is improved, the moisture is better output through the exhaust port of the top cover 2, avoiding the problem that the wet material has poor fluidity and sticks to each other and cannot be fully mixed. The moisture is effectively mixed at a higher level. At the same time, the air supply structure uses the motor 1 as the power, reduces the use of electrical equipment, and reduces the cost of use.
