Description

Technical Field

[0001] This utility model belongs to the field of aggregate cleaning equipment, specifically relating to an integrated gravel aggregate cleaning equipment. Background Technology

[0002] In aggregate production, initial screening and washing are often required. Sand smaller than 4.75mm is screened out and further washed by subsequent equipment in the production line, while gravel larger than 4.75mm is conveyed and stockpiled for further crushing and sand making or sold as gravel. Aggregates typically contain other impurities, such as inherent materials (sludge, iron), organic materials (grass, leaves, roots, wood, branches), and man-made waste (plastic blocks, plastic bags, hair). These impurities are often large particles and are discharged with the gravel. To produce cleaner aggregates free of these impurities, aggregate processing is necessary. Traditional processing methods often involve production lines where various equipment are connected by belt conveyors, resulting in a large footprint and requiring further improvement. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an integrated gravel aggregate washing device.

[0004] The present invention adopts the following technical solution:

[0005] An integrated gravel aggregate washing device includes a frame and a water washing device and a stone washing device mounted on the frame.

[0006] The washing device washes the incoming gravel and includes a washing screen mounted on a frame, a discharge hopper connected to the bottom of the washing screen, and a feed hopper located at the discharge end of the washing screen.

[0007] The stone washing device, located below the water washing device and connected to the feeding hopper, performs secondary washing of the gravel after it has been washed by the water washing device. It includes a stone washing mechanism installed at an incline on the frame, a dewatering mechanism located at the lower end of the stone washing mechanism on the frame, a screening mechanism located on the frame and connected to the upper end of the stone washing mechanism, an overflow conveying mechanism located between the stone washing mechanism and the dewatering mechanism, and a wastewater collection mechanism located below the frame and connected to the dewatering mechanism and the screening mechanism respectively.

[0008] Furthermore, the hopper includes a hopper body, four sliding wheels arranged in a matrix on the outside of the hopper body, and a handle provided on the hopper body.

[0009] Furthermore, the washing device includes multiple mounting seats mounted on the frame for mounting the washing screen. Each mounting seat includes a first mounting body mounted on the frame, a second mounting body mounted on the side of the washing screen opposite to the first mounting body, and multiple buffer springs connecting the first mounting body and the second mounting body.

[0010] Furthermore, the overflow conveying mechanism includes an overflow port located on the lower side of the stone washing mechanism, a diversion box connected to the overflow port, and a drain pipe with one end connected to the diversion box and the other end extending to the dewatering mechanism.

[0011] Furthermore, the drainage box includes a drainage box body and a first mounting edge disposed at the front end of the drainage box body and connected to the overflow port, and the drain pipe is connected to the drainage box body.

[0012] Furthermore, the wastewater collection mechanism includes a wastewater tank, a slurry pump connected to the wastewater tank, a first drain pipe connected between the wastewater tank and the dewatering mechanism, and a second drain pipe connected between the wastewater tank and the screening mechanism.

[0013] Furthermore, the stone washing mechanism includes a spiral stone washing machine installed at an incline on the frame, a feed inlet located at the lower end of the spiral stone washing machine, a discharge outlet located at the upper end of the spiral stone washing machine extending downward into the screening mechanism, and a baffle plate covering the upper surface of the spiral stone washing machine, wherein the discharge hopper is vertically opposite to the feed inlet.

[0014] Furthermore, the stone washing mechanism also includes two first support legs that are mounted on the frame and connected to the upper end of the spiral stone washing machine, and two second support legs that are mounted on the frame and connected to the lower end of the spiral stone washing machine.

[0015] Furthermore, the first support foot includes a telescopic rod mounted on the frame, a first lower hinge seat mounted on the top of the telescopic rod, and a first upper hinge seat mounted at the bottom of the upper end of the spiral stone washing machine and hinged to the first lower hinge seat. The second support foot includes a second lower hinge seat mounted on the frame and a second upper hinge seat mounted at the bottom of the lower end of the spiral stone washing machine and intersecting with the second lower hinge seat.

In addition, the specific structural composition of the stone washing device is defined, with screening and dewatering mechanisms respectively set at the finished product outlet and suspended impurity outlet of the secondary washing of gravel aggregate, maximizing the yield of finished gravel and impurities with low water content. The desorbed water can be reused in the production line, realizing the recycling of water resources. Attached Figure Description

Detailed Implementation

[0027] The present invention will be further described below through specific embodiments.

[0028] Reference Figures 1 to 8 As shown, an integrated gravel aggregate washing equipment includes a frame 1, a water washing device 2 and a stone washing device 3 mounted on the frame 1, and a maintenance platform 4 surrounding the water washing device 2 and the stone washing device 3, wherein the maintenance platform 4 has a U-shaped flow design.

[0029] The washing device 2 washes the incoming gravel aggregate and includes a washing screen 21 mounted on the frame 1, a discharge hopper 22 connected to the bottom of the washing screen 21, a feed hopper 23 located at the discharge end of the washing screen 21, and multiple mounting seats 24 mounted on the frame 1 for mounting the washing screen 21. Specifically, the feed hopper 23 includes a feed hopper body 231, four sliding wheels 232 arranged in a matrix on the outside of the feed hopper body 231, and a handle 233 mounted on the feed hopper body 231. The mounting seats 24 include a first mounting seat body 241 mounted on the frame 1, a second mounting seat body 242 located on the side of the washing screen 21 opposite to the first mounting seat body 241, and multiple buffer springs 243 connecting the first mounting seat body 241 and the second mounting seat body 242. The specific structure of the feed hopper 23 allows it to be pulled out by the handle 233 during equipment maintenance, greatly reducing the difficulty of maintenance.

[0030] The stone washing device 3 is located below the water washing device 2 and is connected to the hopper 23. It performs secondary washing on the gravel aggregate after the water washing device 2 has been washed. It includes a stone washing mechanism 5 that is inclinedly installed on the frame 1, a dewatering mechanism 6 located on the frame 1 at the lower end of the stone washing mechanism 5, a screening mechanism 7 located on the frame 1 and connected to the upper end of the stone washing mechanism 5, an overflow conveying mechanism 8 located between the stone washing mechanism 5 and the dewatering mechanism 6, and a wastewater collection mechanism 9 located below the frame 1 and connected to the dewatering mechanism 6 and the screening mechanism 7 respectively.

[0031] The stone washing mechanism 5 includes a spiral stone washing machine 51 mounted inclined on a frame 1, a feed inlet 52 located at the lower end of the spiral stone washing machine 51, a discharge outlet 53 located at the upper end of the spiral stone washing machine 51 extending downward into the screening mechanism 7, a baffle plate 54 covering the upper surface of the spiral stone washing machine 51, two first support legs 55 located on the frame 1 and connected to the upper end of the spiral stone washing machine 51, and two second support legs 56 located on the frame 1 and connected to the lower end of the spiral stone washing machine 51. Specifically, the first support legs 55 include a telescopic rod 551 located on the frame 1, a first lower hinge seat 552 located at the top of the telescopic rod 551, and a first upper hinge seat 553 located at the bottom of the upper end of the spiral stone washing machine 51 and hinged to the first lower hinge seat 552; the second support legs 56 include a second lower hinge seat 561 located on the frame 1 and... The second upper hinge seat 562, which is hinged to the second lower hinge seat 561 at the bottom of the spiral stone washing machine 51, limits the structure of the first support foot 55 to facilitate the adjustment of the installation angle of the spiral stone washing machine 51 on the frame 1 according to the aggregate condition. Furthermore, the spiral stone washing machine 51 is a commonly used device in the field of aggregate processing equipment, and its specific structure and working principle will not be described in detail here. The spiral stone washing machine 51 is installed on the frame 1 at a 10° inclination, which can effectively increase the residence time of gravel aggregate, thereby increasing the cleaning effect and reducing the output water content. During operation, the gravel aggregate is cleaned by high-intensity twin-shaft agitation in conjunction with its internal spray pipes. The cleaned gravel aggregate enters the screening mechanism 7 through the discharge port 53, and light materials and wastewater are discharged to the dewatering mechanism 6 through the overflow conveying mechanism 8.

[0032] The dewatering mechanism 6 includes a dewatering screen 61 mounted on the frame 1, a vibrating motor 62 mounted on the dewatering screen 61, a shock-absorbing mounting base 63 mounted on the frame 1 for mounting the dewatering screen 61, and a mounting plate 64 mounted on the dewatering screen 61 for mounting the vibrating motor 62. Specifically, the dewatering screen 61 is a commonly used piece of equipment in the aggregate processing field. Its specific structure and working principle will not be further elaborated here. Under normal working conditions, the light materials entering the dewatering screen 61 also contain some sand. The dewatering screen 61 is also equipped with a spray pipe to prevent the light materials from clogging the screen. The wastewater generated will be collected in the wastewater collection mechanism 9 for temporary storage, so as to facilitate subsequent wastewater treatment or water replenishment needs of the production line.

[0033] The screening mechanism 7 includes a linear screen 71 mounted on the frame 1, a discharge port 72 at the discharge end of the linear screen 71, a spray assembly 73 mounted on the linear screen 71, and multiple buffer and shock-absorbing seats 74 mounted on the frame 1 for mounting the linear screen 71. Specifically, the buffer and shock-absorbing seat 74 includes a first seat body 741 mounted on the frame 1, a second seat body 742 mounted on the side wall of the linear screen 71, and multiple shock-absorbing springs 743 connecting the first seat body 741 and the second seat body 742. Furthermore, the linear screen 71 is a commonly used device in the field of aggregate processing, and its specific structure and working principle will not be further elaborated here. The washed aggregate enters the linear screen 71 from the discharge port. When the linear screen 71 is working, the nozzles spray the aggregate to further wash it, preventing some aggregate from not being washed clean in the stone washing machine. The resulting wastewater and light substances flow into the bottom of the linear screen 71 and finally enter the wastewater collection mechanism 9.

[0034] The overflow conveying mechanism 8 includes an overflow port 81 located on the lower side of the stone washing mechanism 5, a diversion box 82 connected to the overflow port 81, and a drain pipe 83 connected at one end to the diversion box 82 and extending to the dewatering screen 61 at the other end. Specifically, the diversion box 82 includes a diversion box body 821 and a first mounting edge 822 located at the front end of the diversion box body 821 and connected to the overflow port 81. The drain pipe 83 is connected to the diversion box body 821.

[0035] The wastewater collection mechanism 9 includes a wastewater tank 91, a slurry pump connected to the wastewater tank 91, a first drain pipe 92 connected between the wastewater tank 91 and the dewatering mechanism 6, and a second drain pipe 93 connected between the wastewater tank 91 and the screening mechanism 7. The slurry pump can periodically pump wastewater from the wastewater tank 91 for fine sand recovery to obtain clean, low-sand-content fine sand. Wastewater generated by the washing screen 21 can also be sent into the wastewater tank 91 through the pipeline.

[0036] This application defines the structural composition of the gravel washing equipment. Through high integration, the raw materials enter the next process by their own weight, greatly reducing the floor space required. The modular design of each device makes it compliant with road transport standards, making transportation more convenient. Each device only needs to be pre-processed and pre-assembled in the factory before being shipped to the site for assembly, making it simpler. In addition, the application specifically defines the structural composition of the stone washing device 3. Screening mechanism 7 and dewatering mechanism 6 are respectively set at the finished product outlet and suspended impurity outlet of the secondary gravel aggregate washing, which maximizes the yield of finished gravel and impurities with low water content. The dewatered water can be reused in the production line, realizing the recycling of water resources.

[0037] The above description is merely a preferred embodiment of the present utility model, and therefore cannot be construed as limiting the scope of the present utility model. All equivalent changes and modifications made in accordance with the scope of the present utility model application and the contents of the specification should still fall within the scope of the present utility model application.
