Description

Technical Field

[0001] The present invention relates to the field of concrete production, and more specifically, relates to an energy-saving and environment-friendly concrete production apparatus and production method. Background Art

[0002] Concrete, commonly abbreviated as "tóng", is a general term for engineering composite materials in which aggregates are bound into a whole by cementitious materials. The term concrete in the usual sense refers to cement concrete obtained by using cement as the cementitious material, sand and stone as aggregates, mixed with water (which may contain admixtures and additives) in a certain proportion and stirred, also known as ordinary concrete. It is widely used in civil engineering. Concrete features rich raw materials, low price and simple production process, so its consumption is increasing more and more.

[0003] The patent with publication number CN202010881612.1 in the prior art discloses a concrete mixing apparatus, which includes a mixing cylinder, a fixing base and a connecting cylinder. A second connecting cavity is vertically opened at the center of the fixing base, and three material storage cavities are opened at equal intervals around the second connecting cavity inside the fixing base outside the second connecting cavity. It can effectively mix concrete, but the above technical solution has the following defects: it cannot realize intermittent addition of raw materials during concrete processing, and the overall mixing by putting all materials into the mixing cylinder leads to poor mixing uniformity, requires a long mixing time, and cannot sieve out materials with relatively large sizes, which affects the finished product quality of the subsequently processed concrete.

[0028] Where there is no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0029] The following is in conjunction with the appendix Figure 1-14 The present invention will be described in further detail below.

[0030] Example 1 Figure 1-13 An embodiment of the present invention is shown. An energy-saving and environmentally friendly concrete production device of the present invention includes: a mixing box 1; an interval control screen plate 2 is provided at the inlet 1-1 of the mixing box 1; the interval control screen plate 2 is connected to a control drive mechanism 3 disposed outside the mixing box 1; two mixing roller mechanisms 4 are arranged opposite to each other inside the mixing box 1, and the two mixing roller mechanisms 4 are connected to a mixing drive mechanism 5 disposed outside the mixing box 1; the mixing drive mechanism 5 is connected to the control drive mechanism 3.

[0031] This invention discloses an energy-saving and environmentally friendly concrete production device. During concrete production, the raw material used can be recycled waste construction materials, effectively utilizing the recycled waste to achieve energy conservation and environmental protection. During production, the mixing drive mechanism 5 is activated, driving two mixing roller mechanisms 4 to operate. Water and cement for concrete production are first added to the mixing tank 1 through the inlet 1-1, and the two mixing roller mechanisms 4 mix the water and cement to form a cement slurry. Fine aggregate is then added to the mixing tank 1 through the inlet 1-1, and the two mixing roller mechanisms 4 mix the cement slurry and fine aggregate. Coarse aggregate is then added to the mixing tank 1 through the inlet 1-1. The material control drive mechanism 3 is activated, which controls the operation of the interval material control screen 2. This allows the interval material control screen 2 to screen the coarse aggregate while simultaneously controlling the intermittent falling of the coarse aggregate. The cement slurry, fine aggregate, and coarse aggregate are mixed evenly by two mixing roller mechanisms 4 to obtain the finished concrete product. In this invention, an interval material control screen 2 is provided at the inlet of the mixing box 1. The interval material control screen 2 is connected to the material control drive mechanism 3 located outside the mixing box, which enables the intermittent addition of raw materials during concrete processing. The raw materials to be mixed are added while mixing, resulting in a reasonable proportion, good mixing uniformity, and less mixing time. Furthermore, the interval material control screen 2 can screen out larger-sized materials, ensuring the quality of the finished concrete product.

[0032] The interval control screen plate 2 includes two sliding partitions 2-1 that slide relative to each other on the side wall of the mixing box 1. The inner ends of the two sliding partitions 2-1 are rotatably connected to two tilting screen plates 2-2, and the outer ends of the two sliding partitions 2-1 are connected to two movable racks 2-3. The two movable racks 2-3 are respectively set at both ends of the control drive mechanism 3. The two tilting screen plates 2-2 are hinged together by a hinge seat 2-4. A sliding shaft 2-5 is rotatably connected to the hinge seat 2-4. One end of the sliding shaft 2-5 slides in the side groove of the inner wall of the mixing box 1, and the other end slides in the longitudinal slide rail of the side wall of the mixing box 1. A protective baffle 2-6 connected to the sliding shaft 2-5 slides in a sealed manner on the outer wall of the mixing box 1, and the protective baffle 2-6 covers the outside of the longitudinal slide rail of the side wall of the mixing box 1.

[0033] After the material control drive mechanism 3 is started, it can control the two movable racks 2-3 to slide inward or outward simultaneously. When the two movable racks 2-3 slide inward simultaneously, it controls the two sliding partitions 2-1 to move closer to each other. The two sliding partitions 2-1 drive the two tilting screens 2-2 to gradually stand up. The two tilting screens 2-2 drive the hinge seat 2-4 to move upward. The sliding shaft 2-5 rotatably connected to the hinge seat 2-4 slides upward in the side groove on the inner wall of the mixing box 1. When the sliding shaft 2-5 moves, it drives the protective baffle 2-6 to move. The protective baffle 2-6 always covers the outside of the longitudinal slide on the side wall of the mixing box 1 to prevent concrete material from leaking out. At this time, the included angle between the two tilting screens 2-2 gradually decreases, and the concrete material stops flowing into the mixing box. When the two movable racks 2-3 slide outwards synchronously, they control the two sliding partitions 2-1 to move away from each other. The two sliding partitions 2-1 drive the two tilting screens 2-2 to gradually flatten. The two tilting screens 2-2 drive the hinge seat 2-4 to move downwards. The sliding shaft 2-5 rotatably connected to the hinge seat 2-4 slides downwards in the sliding groove on the inner wall of the mixing box 1. At this time, the concrete material can fall into the interior of the mixing box 1 through the screen holes of the two tilting screens 2-2 for mixing. This structure not only enables material control and intermittent feeding, but also controls the two tilting screens 2-2 to be in motion, improving the screening effect of the two tilting screens 2-2, reducing the probability of clogging of the two tilting screens 2-2, and improving the feeding effect.

[0034] A limiting support plate is fixed on the outer wall of the mixing box 1, and the limiting support plate slides in cooperation with one side wall of the protective baffle 2-6; a linkage rack rod 1-5 is fixed outside the limiting support plate, and the linkage rack rod 1-5 slides in cooperation with the other side wall of the protective baffle 2-6; the linkage rack rod 1-5 meshes with a linkage gear 2-7 fixed on the sliding shaft 2-5, and two rotating striking frames 2-8 are provided on the sliding shaft 2-5 to strike and vibrate the lower surface of the two tilting screen plates 2-2 through the two rotating striking frames 2-8.

[0035] The limiting support plate slides on one side wall of the protective baffle 2-6, and the linkage rack 1-5 slides on the other side wall of the protective baffle 2-6, which serves to guide and limit the movement of the protective baffle 2-6, ensuring the stability of the up-and-down movement of the protective baffle 2-6. This eliminates the need for a separate limiting structure, allowing the linkage rack 1-5 to perform multiple functions. When the sliding shaft 2-5 moves up and down, it drives the linkage gear 2-7 to move up and down. The linkage gear 2-7 contacts different positions on the linkage rack 1-5 during its up-and-down movement, causing it to rotate around its own axis. The rotation of the linkage gear 2-7 drives the sliding shaft 2-5 and the rotating striking frame 2-8 on the sliding shaft 2-5 to rotate. This causes the two rotating striking frames 2-8 to strike and vibrate the lower surfaces of the two tilting screens 2-2, preventing blockage of the two tilting screens 2-2, improving the cleaning effect of the two tilting screens 2-2, and reducing the frequency of maintenance.

[0036] The rotating striking frame 2-8 includes a rotating seat fixed on a sliding rotating shaft 2-5. Multiple arc-shaped elastic striking plates are evenly rotated around the rotating seat to strike the lower surfaces of the two rotating screen plates 2-2 when the included angle between the two rotating screen plates 2-2 reaches a preset angle. The arc-shaped elastic striking plates are designed so that they do not cause hard damage to the rotating screen plates 2-2 while striking them, and can adaptively adjust their size when the included angle between the rotating screen plates 2-2 becomes smaller.

[0037] The material control drive mechanism 3 includes a material control motor 3-1 disposed outside the mixing box 1. The upper and lower ends of the material control gear 3-2 on the material control motor 3-1 mesh with two movable racks 2-3 to drive the two movable racks 2-3 to move towards each other or away from each other. Two strip-shaped limiting plates 1-6 are also fixed on the mixing box 1. The two strip-shaped limiting plates 1-6 are located on the side of the two movable racks 2-3 away from the material control gear 3-2 and slide with the two movable racks 2-3.

[0038] After the material control motor 3-1 starts, it drives the material control gear 3-2 to rotate. The material control motor 3-1 is a forward and reverse motor, which can drive the material control gear 3-2 to rotate forward or reverse. The rotation of the material control gear 3-2 can drive the two movable racks 2-3 to slide inward or outward simultaneously. The two strip-shaped limiting plates 1-6 are located on the side of the two movable racks 2-3 away from the material control gear 3-2, and slide with the two movable racks 2-3 to limit the two movable racks 2-3 and improve the stability of the meshing connection between the two movable racks 2-3 and the material control gear 3-2.

[0039] The production device further includes a feeding roller mechanism 6, which includes a feeding shaft 6-1 that slides on the inner wall of the mixing box 1. Multiple feeding roller bodies 6-3 are fixed relatively on the left and right sides of the feeding shaft 6-1. The feeding shaft 6-1 is fixed below the hinge seat 2-4 by a hanger 6-2. The mixing roller mechanism 4 includes a mixing shaft 4-1 that is rotatably connected to the mixing box 1. Multiple sets of mixing roller bodies 4-2 are evenly arranged around the shaft of the mixing shaft 4-1 located inside the mixing box 1. The mixing shaft 4-1 extends out to a mixing friction disc 4-3 fixed at one end of the mixing box 1 and is connected to the mixing drive mechanism 5. The multiple feeding roller bodies 6-3 that are fixed relatively on the left and right sides of the feeding shaft 6-1 are respectively arranged between the multiple sets of mixing roller bodies 4-2 of the two mixing roller mechanisms 4.

[0040] After the mixing drive mechanism 5 is started, it can control the two mixing friction discs 4-3 of the two mixing roller mechanisms 4 to rotate in different directions. The two mixing friction discs 4-3 drive the two mixing shafts 4-1 to rotate in different directions, thereby driving the multiple sets of mixing roller bodies 4-2 on the two mixing shafts 4-1 to rotate and circle in different directions to fully mix the concrete materials. During the mixing process, the concrete materials can also be turned up and down by the material-pulling roller mechanism 6. When the hinge seat 2-4 moves up and down, the material-pulling shaft 6-1 can be driven up and down in the groove on the inner wall of the mixing box 1 by the hanger 6-2. Thus, the material-pulling shaft 6-1 drives the multiple material-pulling roller bodies 6-3 to perform reciprocating sliding motion in the up and down direction. The multiple material-pulling roller bodies 6-3 are inserted between the multiple sets of mixing roller bodies 4-2 of the two mixing roller mechanisms 4 to turn up and down the concrete materials being mixed, thereby improving the mixing effect and mixing efficiency.

[0041] The mixing drive mechanism 5 includes a mixing motor 5-1 mounted on the mixing box 1. The mixing motor 5-1 is connected to a rotating horizontal shaft 5-2 rotatably connected to the mixing box 1. Two rotating horizontal tubes 5-3 are slidably connected to the rotating horizontal shaft 5-2. The sliders inside the two rotating horizontal tubes 5-3 slide in the axial horizontal grooves on the rotating horizontal shaft 5-2. A driving friction disc 5-4 is fixedly connected to each of the two rotating horizontal tubes 5-3. The two driving friction discs 5-4 are perpendicularly frictionally connected to the mixing friction discs 4-3 of the two mixing roller mechanisms 4. The two driving friction discs 5-4 are located inside the two mixing friction discs 4-3. The two rotating horizontal tubes 5-3 are rotatably connected to two tube seats 5-5. The two tube seats 5-5 are rotatably connected to the lower ends of two linkage inclined rods 5-6. The upper ends of the two linkage inclined rods 5-6 are rotatably mounted on a speed regulating frame 5-7. The speed regulating frame 5-7 is fixedly connected to the bottom of the protective baffle 2-6.

[0042] After the mixing motor 5-1 starts, it drives the rotating horizontal shaft 5-2 to rotate. When the rotating horizontal shaft 5-2 rotates, it drives the two rotating horizontal tubes 5-3 to rotate through the cooperation of the axial horizontal groove and the two sliders, thereby driving the two driving friction discs 5-4 to rotate. The two driving friction discs 5-4 are located inside the two mixing friction discs 4-3, so that when the two driving friction discs 5-4 rotate, they can drive the two mixing friction discs 4-3 to rotate in different directions. The contact position between the two driving friction discs 5-4 and the two mixing friction discs 4-3 can be adjusted to change the mixing speed and achieve variable speed mixing. This variable speed adjustment is automatically adjusted with the feeding speed of the two tilting screen plates 2-2. As the two tilting screen plates 2-2 gradually level, the concrete material falls into the mixing box 1 for mixing. At this time, the protective baffle... Plate 2-6 drives the speed regulating frame 5-7 to move downwards. The speed regulating frame 5-7, through two linkage inclined rods 5-6, drives the two rotating horizontal tubes 5-3 to move away from each other. The two rotating horizontal tubes 5-3 drive the two driving friction discs 5-4 to move towards the center of the two mixing friction discs 4-3, thereby increasing the mixing speed and achieving a synchronous increase in mixing speed when new concrete material is added, so as to ensure the mixing effect. When the two tilting screen plates 2-2 gradually stand upright, the protective baffle 2-6 drives the speed regulating frame 5-7 to move upwards. The speed regulating frame 5-7, through two linkage inclined rods 5-6, drives the two rotating horizontal tubes 5-3 to move closer to each other. The two rotating horizontal tubes 5-3 drive the two driving friction discs 5-4 to move away from the center of the two mixing friction discs 4-3, thereby reducing the mixing speed. The speed is automatically adjusted without human intervention.

[0043] The production device further includes a swaying seat mechanism 7, which includes a tilting bracket 7-1. One end of the tilting bracket 7-1 is fixed to the mixing box 1, and the other end of the tilting bracket 7-1 is rotatably connected to one end of the top surface of the base 7-2. The other end of the top surface of the base 7-2 is rotatably connected to one end of the swing arm 7-3, and the other end of the swing arm 7-3 is rotatably connected to the eccentric column 7-4. The eccentric column 7-4 is fixed at the eccentric position of the rotating worm wheel 7-5. The rotating worm wheel 7-5 rotates on the mixing box 1 through a wheel axle and meshes with a worm fixed to the rotating horizontal shaft 5-2. The mixing box 1 has two inwardly inclined feeding slopes at the inlet 1-1. The outlet 1-2 of the mixing box 1 is located below the side of the mixing box 1. The outlet 1-2 of the mixing box 1 is sealed and slidably fitted with the outlet baffle 1-3. The outlet baffle 1-3 is connected to the cylinder shaft of the baffle cylinder 1-4. The baffle cylinder 1-4 is installed on the mixing box 1.

[0044] When the horizontal axis 5-2 rotates, it drives the worm to rotate, which in turn rotates the worm wheel 7-5 through meshing. The worm wheel 7-5 and the worm are configured to control the tilt angle of the discharge port 1-2 of the mixing box 1, facilitating material discharge. A discharge baffle 1-3 is provided at the discharge port 1-2 of the mixing box 1 for sealing and sliding. The discharge baffle 1-3 is connected to the cylinder shaft of the baffle cylinder 1-4. The discharge baffle 1-3 can be controlled by the baffle cylinder 1-4 to seal or unseal the discharge port 1-2, thereby controlling the material discharge. The seat mechanism 7 improves the mixing effect and fluidity of the concrete in the mixing bin 1. The worm gear meshes with the rotating worm wheel 7-5, which in turn drives the eccentric column 7-4 to rotate and circulate. When the eccentric column 7-4 rotates and circulates, it changes the angle between the mixing bin 1 and the tilting bracket 7-1 and the base 7-2 through its cooperation with one end of the swing arm 7-3. This controls the mixing bin 1 to shake at a certain angle, improving the mixing effect and fluidity of the concrete in the mixing bin 1, and further improving the quality of the finished concrete.

[0045] Example 2 Figure 1-13 Another embodiment of the present invention is shown, a production method of the present invention applied to the aforementioned energy-saving and environmentally friendly concrete production device, comprising: Turn on the mixing drive mechanism 5 to drive the two mixing roller mechanisms 4 to operate. Water and cement for concrete production are first added into the mixing tank 1 through the inlet 1-1. The water and cement are then mixed by two mixing roller mechanisms 4 to form cement slurry. Fine aggregate is fed into mixing tank 1 through inlet 1-1, and the cement slurry and fine aggregate are mixed by two mixing roller mechanisms 4. Coarse aggregate is fed into the mixing box 1 through the feed inlet 1-1, and the material control drive mechanism 3 is turned on. The material control drive mechanism 3 controls the operation of the interval material control screen plate 2, so that the interval material control screen plate 2 screens the coarse aggregate while controlling the coarse aggregate to fall intermittently. The cement slurry, fine aggregate, and coarse aggregate are mixed evenly by two mixing rollers to obtain the finished concrete product.

[0046] In one production method of the present invention, coarse aggregate is fed into the mixing tank 1 through the feed inlet 1-1, and the material control drive mechanism 3 is activated. The material control drive mechanism 3 controls the operation of the interval control screen plate 2, so that the interval control screen plate 2 screens the coarse aggregate while controlling the coarse aggregate to fall intermittently. This allows for the intermittent addition of raw materials during concrete processing. The raw materials to be mixed are added while stirring, resulting in a reasonable proportion, good mixing uniformity, and less mixing time. In addition, the interval control screen plate 2 can screen out larger-sized materials, ensuring the quality of the finished concrete product.

[0047] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. It should be noted that those skilled in the art can make various improvements and modifications to this application without departing from its principles, and these improvements and modifications also fall within the scope of protection of the claims.
