Description

Technical Field

[0001] This utility model relates to the field of construction waste treatment, and in particular to a construction waste recycling mixing device. Background Technology

[0002] Construction waste refers to the excavated soil, materials, and other solid waste generated by construction units and contractors during the construction, renovation, expansion, and demolition of various buildings, structures, and pipelines, as well as during the decoration and renovation of homes by residents. Nowadays, by crushing and further pulverizing construction waste, and then using the fine powder, cement, and admixtures as the main raw materials, engineering filling materials are produced, enabling the recycling of construction waste. These materials can be used in municipal pipeline trenches, foundation pit backfilling, foundation treatment and roadbed replacement, and foundation pit roof filling, thus allowing construction waste to be reused.

[0003] Currently, when preparing engineering filling materials using construction waste powder and cement as the main raw materials, a mixing device is required. When mixing construction waste powder and cement using the mixing device, the construction waste powder and cement need to be poured into the mixing tank one after the other. When the construction waste powder and cement are poured into the tank one after the other, a layer of construction waste powder and a layer of cement are formed. These two layers of raw materials are stacked together on top of each other. Although the mixing is carried out by the stirring rod, it is not easy to fully mix them because the two layers of raw materials are stacked in layers, resulting in poor mixing effect. Utility Model Content

[0004] (I) Purpose of the utility model

[0005] In view of this, the purpose of this utility model is to propose a construction waste recycling mixing device. The technical problem to be solved is that when using the mixing device to mix construction waste powder and cement, the construction waste powder and cement need to be poured into the mixing tank one after the other. When the construction waste powder and cement are poured into the tank one after the other, a construction waste powder layer and a cement layer are formed. Moreover, the two layers of raw materials are stacked together on top of each other. Although the mixing is carried out by the stirring rod, it is not easy to fully mix them by stirring alone because the two layers of raw materials are stacked in layers, resulting in poor mixing effect.

[0006] (II) Technical Solution

[0007] To achieve the above technical objectives, this utility model provides a construction waste recycling mixing and stirring device:

[0008] It includes a mixing tank, a cover plate on the top of the mixing tank, two storage cylinders fixed inside the cover plate, a guide cylinder fixed and connected to the bottom of the storage cylinders, an inclined guide plate fixed to the bottom of the guide cylinder, multiple guide grooves evenly spaced inside the inclined guide plate, a motor installed on the top of the cover plate, a rotating rod rotatably connected inside the cover plate, multiple stirring paddles fixed to the outside of the rotating rod, a support plate fixed to the bottom of the guide grooves, and a striking component for striking the inclined guide plate inside the support plate.

[0009] Preferably, the striking component includes a travel groove formed in the support plate, a movable plate slidably connected in the travel groove, a first connecting plate provided on the top of the movable plate, a striking rod fixed at one end of the first connecting plate, and a receiving plate provided at the bottom of the inclined guide plate.

[0010] Preferably, a second connecting plate is provided at the bottom of the movable plate, a first semi-circular plate is fixed at one end of the second connecting plate, two rectangular rods are fixed on the outer side of the top of the rotating rod, a U-shaped plate is provided on the outer side of the rectangular rods, and a second semi-circular plate is fixed on one side of the U-shaped plate.

[0011] Preferably, a guide rod is fixed inside the travel groove, the guide rod passes through the movable plate, the movable plate is slidably fitted outside the guide rod, a spring is sleeved on the outside of the guide rod, one end of the spring abuts against the movable plate, and the other end of the spring abuts against the inner wall of the travel groove.

[0012] Preferably, an inclined plate is fixed inside the storage cylinder, a limiting sleeve is provided at the bottom of the mixing tank, the rotating rod can be embedded in the limiting sleeve and rotate within the limiting sleeve, and four supports are fixed at equal intervals along the radial direction on the outside of the limiting sleeve, with the end of the support away from the limiting sleeve fixed to the inner wall of the mixing tank.

[0013] Preferably, a plurality of first bolts pass through the cover plate, and the first bolts are threadedly connected to the top of the mixing tank. Two second bolts pass through the mixing tank and are threadedly connected to the support plate. A fourth bolt passes through the first connecting plate and is threadedly connected to the moving plate. A third bolt passes through the impact plate and is threadedly connected to the inclined guide plate. A fifth bolt passes through the second connecting plate and is threadedly connected to the moving plate. A sixth bolt passes through the U-shaped plate and is threadedly connected to the rectangular rod.

[0014] As can be seen from the above technical solutions, this application has the following beneficial effects:

[0015] 1. Because the two inclined guide plates are set at an angle, when the construction waste powder and cement are conveyed from the guide troughs of the two inclined guide plates into the mixing tank, after the construction waste powder and cement are discharged from different guide troughs, they will be mixed together and conveyed into the mixing tank. Then, under the stirring of the mixing slurry, the two will be mixed again, so that the construction waste powder and cement can be fully mixed.

[0016] 2: When the rotating rod rotates, it drives the rectangular rod and the second semi-circular plate to rotate. When the second semi-circular plate rotates to press against the first semi-circular plate, it drives the first semi-circular plate and the second connecting plate to move. When the second connecting plate moves, it drives the moving plate, the first connecting plate, and the striking rod to move, so that the striking rod moves away from the impact plate. When the second semi-circular plate rotates until it no longer presses against the first semi-circular plate, the spring rebound force drives the moving plate, the first connecting plate, and the striking rod to move closer to the impact plate. When the striking rod hits the impact plate, it will cause the inclined guide plate to vibrate, which facilitates the smooth conveying of construction waste powder and cement in the guide trough into the mixing tank.

[0024] The following description is exemplary in nature and is not intended to limit the scope, application, or use of this disclosure. It should be understood that in all these figures, the same or similar reference numerals indicate the same or similar parts and features. The figures are merely schematic representations of the concept and principles of embodiments of this disclosure and do not necessarily show the specific dimensions and scale of the various embodiments of this disclosure. Certain details or structures of embodiments of this disclosure may be exaggerated in particular portions of certain figures.

[0025] Reference Figure 1-5 :

[0026] In one embodiment of this utility model, a construction waste recycling mixing device is provided, including a mixing tank 1, a cover plate 2 on the top of the mixing tank 1, two storage cylinders 3 fixed inside the cover plate 2, a guide cylinder 4 fixed and connected to the bottom of the storage cylinders 3, an inclined guide plate 5 fixed to the bottom of the guide cylinder 4, multiple guide grooves 6 evenly spaced inside the inclined guide plate 5, a motor 7 installed on the top of the cover plate 2, a rotating rod 8 rotatably connected inside the cover plate 2, multiple mixing slurries 9 fixed to the outside of the rotating rod 8, a support plate 10 fixed to the bottom of the guide grooves 6, and a striking component for striking the inclined guide plate 5 inside the support plate 10.

[0027] When using construction waste powder and cement as the main raw materials to prepare engineering filling materials, the construction waste powder and cement are first poured into two storage cylinders 3 respectively, so that the construction waste powder and cement flow through the guide cylinder 4 to the guide trough 6 of the inclined guide plate 5. Since the two inclined guide plates 5 are set at an inclination, when the construction waste powder and cement are conveyed from the guide trough 6 of the two inclined guide plates 5 to the mixing tank 1, after the construction waste powder and cement are discharged from different guide troughs 6, they will be mixed together and conveyed into the mixing tank 1. Then, under the stirring of the mixing slurry 9, the two are mixed again, so that the construction waste powder and cement can be fully mixed.

[0028] The striking assembly includes a travel groove 11 formed in the support plate 10, a movable plate 12 slidably connected in the travel groove 11, a first connecting plate 13 on the top of the movable plate 12, a striking rod 14 fixed to one end of the first connecting plate 13, a receiving plate 15 at the bottom of the inclined guide plate 5, a second connecting plate 16 at the bottom of the movable plate 12, a first semi-circular plate 17 fixed to one end of the second connecting plate 16, two rectangular rods 18 fixed to the outer side of the top of the rotating rod 8, a U-shaped plate 19 on the outer side of the rectangular rods 18, a second semi-circular plate 20 fixed to one side of the U-shaped plate 19, a guide rod 21 fixed in the travel groove 11, the guide rod 21 passing through the movable plate 12, the movable plate 12 slidably fitting outside the guide rod 21, a spring 22 sleeved on the outer side of the guide rod 21, one end of the spring 22 abutting against the movable plate 12, and the other end of the spring 22 abutting against the inner wall of the travel groove 11.

[0029] In use, the motor 7 is started to drive the rotating rod 8 to rotate. When the rotating rod 8 rotates, it drives the mixing paddle 9 to stir the raw materials in the mixing tank 1. When the rotating rod 8 rotates, it also drives the rectangular rod 18 and the second semi-circular plate 20 to rotate. When the second semi-circular plate 20 rotates to press against the first semi-circular plate 17, it drives the first semi-circular plate 17 and the second connecting plate 16 to move. When the second connecting plate 16 moves, it drives the moving plate 12 to move. When the moving plate 12 moves, it drives the first connecting plate 13 and the striking rod 14 to move, so that the striking rod 14 moves away from the impact plate 15. When the moving plate 12 moves, it compresses the spring 22. When the second semi-circular plate 20 rotates until it no longer presses against the first semi-circular plate 17, the spring 22 rebounds and drives the moving plate 12. The first connecting plate 13 and the striking rod 14 move toward the impact plate 15. When the striking rod 14 hits the impact plate 15, it will cause the inclined guide plate 5 to vibrate, thereby facilitating the smooth conveying of construction waste powder and cement in the guide trough 6 into the mixing tank 1. It should be noted that the motors 7 in this embodiment are all conventional equipment known to those skilled in the art and can be selected or customized according to actual needs. In this embodiment, we only use them and do not improve their structure and function. For those skilled in the art, the setting method, installation method and electrical connection method can be adjusted and operated according to the requirements of the instruction manual, and will not be described in detail here.

[0030] In addition, an inclined plate 23 is fixed inside the storage cylinder 3, and a limiting sleeve 24 is provided at the bottom of the mixing tank 1. The rotating rod 8 can be embedded in the limiting sleeve 24 and rotate within the limiting sleeve 24. Four supports 25 are fixed at equal intervals along the radial direction on the outside of the limiting sleeve 24. The end of the support 25 away from the limiting sleeve 24 is fixed to the inner wall of the mixing tank 1. Multiple first bolts 26 pass through the cover plate 2. The first bolts 26 are threaded to the top of the mixing tank 1. Two second bolts 27 pass through the mixing tank 1. The second bolts 27 are threaded to the support plate 10. A fourth bolt 29 passes through the first connecting plate 13. The fourth bolt 29 is threaded to the moving plate 12. A third bolt 28 passes through the impact plate 15. The third bolt 28 is threaded to the inclined guide plate 5. A fifth bolt 30 passes through the second connecting plate 16. The fifth bolt 30 is threaded to the moving plate 12. A sixth bolt 31 passes through the U-shaped plate 19. The sixth bolt 31 is threaded to the rectangular rod 18.

[0031] It should be noted that when the striking rod 14, the impact plate 15, the first semi-circular plate 17, and the second semi-circular plate 20 show wear after long-term use, first remove the first bolt 26 and the second bolt 27, then the cover plate 2, the inclined guide plate 5, the support plate 10, and the rotating rod 8 can be removed from the mixing tank 1 as a whole. Then remove the third bolt 28, the fourth bolt 29, the fifth bolt 30, and the sixth bolt 31 to replace the first connecting plate 13, the striking rod 14, the second connecting plate 16, the first semi-circular plate 17, the U-shaped plate 19, and the second semi-circular plate 20.

[0032] The exemplary implementation of the solution proposed in this disclosure has been described in detail above with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
