Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, and more specifically, to aggregate washing equipment for concrete production. Background Technology

[0002] Concrete is a building material used in construction. The production of concrete involves mixing aggregates, cement, sand, and water. Aggregates used in concrete production refer to granular materials used in concrete preparation, including sand and gravel. Aggregates fill voids and increase volume in concrete. During mixing, cement is stirred with water to form a thin paste; without aggregates, it cannot be formed. To ensure the quality of the finished concrete, the surface of the aggregates is cleaned of dust and other impurities.

[0003] For example, the utility model patent with publication number CN221951846U discloses a concrete aggregate cleaning device, including a cleaning tank. A top cover is fixedly connected to the top of the cleaning tank, and a feed inlet is fixedly connected to the top of the top cover. A rectangular opening is formed in the middle of the upper surface of the top cover. A water supply pipe is fixedly connected to one side of the cleaning tank, and a cleaning nozzle is fixedly connected to the bottom of the water supply pipe. A support column is fixedly connected to the bottom of the cleaning tank, and a rubber ring is fixedly connected to the bottom of the support column. An inclined baffle is fixedly connected to the inner bottom wall of the cleaning tank, and a circular opening is formed in the middle of the inner bottom wall of the cleaning tank.

[0004] In existing concrete aggregate washing devices, the structure for aggregate washing is arranged according to the area of ​​the aggregate, which increases the washing cost and water consumption. In addition, the structure for filtering aggregate is prone to clogging, and the clogged filter structure can affect the flow of wastewater. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that addresses the high cost of aggregate cleaning and the tendency for dirt to clog the surface.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a concrete aggregate washing equipment, including a conveying cylinder, an inlet hopper and an outlet hopper fixedly connected to and communicating with the outer surface of the conveying cylinder, filter holes opened on the outer surface of the conveying cylinder, a screw conveying assembly for conveying aggregates arranged inside the conveying cylinder, a washing structure arranged at the top of the conveying cylinder, an anti-clogging structure arranged on the outer surface of the conveying cylinder, and a lifting mechanism arranged on the outside of the conveying cylinder, the lifting mechanism being arranged between the screw conveying assembly and the anti-clogging structure.

[0007] In a preferred embodiment, the spiral conveying assembly includes a drive shaft rotatably connected inside the conveying cylinder, spiral blades fixedly connected to the outer surface of the drive shaft, and a geared motor mounted on the top of the conveying cylinder, the output shaft of the geared motor being fixedly connected to one end of the drive shaft.

[0008] In a preferred embodiment, the cleaning structure includes a water supply pipe, one end of which passes through the conveying cylinder and is fixedly connected to a cleaning disc. The cleaning disc is located outside the drive shaft and above the spiral blades, and a water spray nozzle is provided at the bottom of the cleaning disc.

[0009] In a preferred embodiment, the anti-clogging structure includes a ring plate disposed on the outer side of the conveying cylinder, and a cleaning brush is fixedly connected to the inner wall of the ring plate, the cleaning brush being in movable contact with the filter holes on the conveying cylinder.

[0010] In a preferred embodiment, a mounting frame is fixedly connected to the outer surface of the conveying cylinder, and the lifting mechanism includes a baffle, which is fixedly connected to the mounting frame. A smooth rod is rotatably connected to the inner wall of the baffle. The drive shaft is driven by a belt drive mechanism. A reciprocating thread is provided on the smooth rod, and a lifting block is drivenly connected to the reciprocating thread. The lifting block is slidably connected to the inner wall of the baffle.

[0011] In a preferred embodiment, a connecting frame is fixedly connected to the lifting block, and one end of the connecting frame is connected to the ring plate by bolts.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This aggregate washing equipment for concrete production uses a vertical conveying cylinder as the aggregate conveying pipeline. The screw conveyor component can drive the aggregate to move upward in a stirring manner. The washing structure treats the upward conveyed aggregate with water, so that the dirt on the aggregate can be mixed with the washing water and discharged through the filter holes. Because the aggregate washing is vertical, the washing water can sink along the length of the conveying cylinder under the action of gravity. At the same time, the washing water can mix with the aggregate in the conveying state to flush it. While ensuring the thorough cleaning of the aggregate, the structural layout of the washing structure can be reduced and the water consumption can be reduced.

[0014] 2. In this aggregate cleaning equipment for concrete production, the lifting mechanism can provide lifting power to the anti-clogging structure by means of the power of the screw conveyor assembly. In this way, the cleaning brush can clean the impurities in the filter holes on the outside of the conveying cylinder, thereby cleaning the conveying cylinder and ensuring the reliability of aggregate cleaning.

[0022] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] See also Figures 1-5 This utility model provides aggregate washing equipment for concrete production, including a conveying cylinder 1, an installation frame 10 fixedly connected to the outer surface of the conveying cylinder 1, and a feed hopper 2 and a discharge hopper 3 connected to the outer surface of the conveying cylinder 1.

[0024] The mounting bracket 10 can be bolted to a designated mounting surface, which allows the conveying cylinder 1 to be suspended and kept vertical. The feed hopper 2 can easily feed concrete aggregate into the conveying cylinder 1, and the discharge hopper 3 can be used to discharge the processed aggregate from the conveying cylinder 1.

[0025] In this embodiment, filter holes 4 are provided on the outer surface of the conveying cylinder 1.

[0026] The filter hole 4 can adopt a circular or diamond-shaped hole structure. The filter hole 4 can provide a discharge channel for sewage and at the same time filter the aggregate. Since the conveying cylinder 1 is suspended and kept vertical, in order to prevent sewage passing through the filter hole 4 from polluting the environment, a collection device such as a collection pool can be set at the bottom of the conveying cylinder 1 to receive the sewage falling from the conveying cylinder 1. In this way, the collection pool can collect the sewage.

[0027] In this embodiment: a spiral conveying assembly 5 for conveying aggregate is provided inside the conveying cylinder 1. The spiral conveying assembly 5 includes a drive shaft 51, which is rotatably connected inside the conveying cylinder 1. Spiral blades 52 are fixedly connected to the outer surface of the drive shaft 51. A reduction motor 6 is mounted on the top of the conveying cylinder 1. The output shaft of the reduction motor 6 is fixedly connected to one end of the drive shaft 51.

[0028] In use, the geared motor 6 drives the transmission shaft 51 to rotate. The rotation of the transmission shaft 51 can drive the spiral blades 52 to rotate and convey. The aggregate at the bottom of the conveying cylinder 1 can be conveyed upward by the spiral blades 52 in a stirring manner until it is discharged through the discharge hopper 3.

[0029] In this embodiment: a cleaning structure 7 is provided on the top of the conveying cylinder 1. The cleaning structure 7 includes a water supply pipe 71. One end of the water supply pipe 71 passes through the conveying cylinder 1 and is fixedly connected to a cleaning disc 72. The cleaning disc 72 is located outside the drive shaft 51 and above the spiral blade 52. A water spray nozzle 73 is provided at the bottom of the cleaning disc 72.

[0030] The cleaning disc 72 is a hollow structure, and the water supply pipe 71 is connected to the hollow cleaning disc 72. In this application, the water inlet end of the water supply pipe 71 can be connected to an existing water pump to supply cleaning water. There are multiple spray nozzles 73, and the multiple spray nozzles 73 are distributed in a ring on the cleaning disc 72. When the spiral blades 52 stir and convey the aggregate in the conveying cylinder 1 upward, the cleaning water delivered by the water pump can pass through the water supply pipe 71 and the cleaning disc 72 in sequence, and then spray downward through the spray nozzles 73. Multiple spray nozzles 73 can be set, so that the cleaning water can sink along the conveying cylinder 1 under the action of gravity. Since the spiral blades 52 can stir and convey the aggregate, the cleaning water can wash the moving aggregate to rinse the dirt on the surface of the aggregate. The dirt can be mixed with the cleaning water and discharged through the filter hole 4.

[0031] It should be noted that since the cleaning structure 7 is arranged at the end of the conveying vertical cylinder 1, compared with the traditional cleaning facilities arranged at multiple positions along the moving direction of the aggregate, under the condition of ensuring the quality of aggregate conveying and cleaning, the present application can reduce the facility investment of the cleaning structure 7 and reduce the water consumption.

[0032] In this embodiment: An anti-blocking structure 8 is arranged on the outer surface of the conveying vertical cylinder 1. The anti-blocking structure 8 includes an annular plate 81. The annular plate 81 is arranged outside the conveying vertical cylinder 1. A cleaning brush 82 is fixedly connected to the inner wall of the annular plate 81. The cleaning brush 82 is in active contact with the filter holes 4 on the conveying vertical cylinder 1.

[0033] The cleaning brush 82 is made of nylon brush material. The nylon material has the characteristic of high durability. The annular plate 81 is arranged in a semi-circular structure. In the present application, the anti-blocking structure 8 is arranged in a mirror image of two pairs, so that the cleaning brush 82 can completely cover the outside of the conveying vertical cylinder 1 to clean the blocked filter holes 4.

[0034] In this embodiment: A lifting mechanism 9 is arranged on the outside of the conveying vertical cylinder 1. The lifting mechanism 9 is arranged between the spiral conveying component 5 and the anti-blocking structure 8. The lifting mechanism 9 includes a shield 91. The shield 91 is fixedly connected to the mounting frame 10. A smooth rod 92 is rotatably connected to the inner wall of the shield 91. The transmission shaft 51 is传动连接 (it seems there is a mistake here, should be "driven") with the smooth rod 92 through a belt transmission mechanism. A reciprocating thread 93 is formed on the smooth rod 92. A lifting block 94 is driven and connected to the reciprocating thread 93. The lifting block 94 is slidably connected to the inner wall of the shield 91. A connecting frame 11 is fixedly connected to the lifting block 94. One end of the connecting frame 11 is connected to the annular plate 81 through bolts.

[0035] The shield 91 is arranged in a "U" - shaped structure. While providing guiding and sliding for the lifting block 94, the shield 91 can also block the position of the smooth rod 92, so as to prevent sewage from polluting the smooth rod 92. There are two groups of reciprocating threads 93 arranged on the smooth rod 92. The lifting block 94 is in a "middle" - shaped structure. The belt transmission mechanism is composed of an existing pair of pulleys and an internal - tooth belt drivingly connected to the pair of pulleys. The pair of pulleys are respectively coaxially and fixedly connected to the smooth rod 92 and the transmission shaft 51. When the reduction motor 6 drives the transmission shaft 51 to rotate, the belt transmission mechanism can drive the smooth rod 92 to rotate synchronously. One end of the connecting frame 11 is connected to the annular plate 81 through bolts, which is convenient for disassembling and assembling the annular plate 81, so that the cleaning brush 82 can be easily replaced.

[0036] During use, as the geared motor 6 drives the transmission shaft 51 to move the aggregate conveyor upward, the transmission shaft 51 can drive the guide rod 92 to rotate via the belt transmission mechanism. The reciprocating thread 93 on the guide rod 92 can drive the lifting block 94 to move up and down. In this way, the lifting block 94 can drive the cleaning brush 82 on the ring plate 81 to move up and down via the connecting frame 11. The cleaning brush 82 can make contact with the filter hole 4 on the outer surface of the conveying cylinder 1. The bristles of the cleaning brush 82 can rub the dirt that is blocked in the filter hole 4, so as to clean the filter hole 4 easily and ensure the effective discharge of sewage.
