[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.
[0026] To address the issue of insufficient mixing between materials and modifiers in existing technologies, resulting in poor material modification effects.
[0027] To address the technical problem, this utility model provides a material modification mechanism for grouting materials, which can increase the contact area between the material and the modifier, ensuring that the material and the modifier are fully mixed.
[0028] It should be noted that grouting material is a key material specifically used for grouting construction of post-tensioned prestressed pipes (holes). It is formulated with high-quality cement-based materials and high-performance admixtures. This solution only uses grouting material and modifier as an example. Of course, the material modification mechanism can also be used for other materials that need modification, which will not be elaborated here.
[0029] Please see Figures 1-5 , Figures 1-5 This utility model discloses a material modification mechanism for grouting materials, comprising a modification cylinder 1, a material dispersing unit 2, and a spraying mechanism 3. The modification cylinder 1 has a cavity 1a, and the top of the modification cylinder 1 has a feed end 1b communicating with the cavity 1a. The material dispersing unit 2 includes a material dispersing component 21 and a screening component 22. The material dispersing component 21 is installed inside the cavity 1a and divides the cavity 1a into multiple modification zones. The tops of the multiple modification zones are communicating with the feed end 1b. The screening component 22 is installed on the modification cylinder 1 and located at the connection between the feed end 1b and the modification zones. The screening component 22 has screening sections corresponding to the multiple modification zones. The spraying mechanism 3 includes a spraying component 31, which is installed on the top of the modification zones and can spray modifiers onto each modification zone.
[0030] In actual use, the material is conveyed into the cavity 1a through the feed end 1b. The material first falls onto the screening component 22. The material passes through the screening area on the screening component 22 and can be dispersed into each modification zone. During the process of falling in the modification zone, the material can fully contact the modifier sprayed in the modification zone, which effectively increases the contact area between the material and the modifier.
[0031] It should be noted that the loose material component 21 is not limited to a specific structure, as long as it can be used to divide the cavity into multiple modified areas, and no other limitations are made here.
[0032] In one embodiment, the bulk material component 21 includes a plurality of partitions 211, which are spaced apart and installed in parallel within the cavity 1a, and the modified region is formed between two adjacent partitions 211.
[0033] Specifically, the partition 211 is an alloy plate, which is welded into the cavity 1a. The distance between two adjacent partitions is 50-80mm. The material can be dispersed into each modification zone through the screening section of the screening component 22, which can effectively increase the contact area of the material modifier.
[0034] It should be noted that, in one embodiment, the screening component 22 includes a screen plate 221 and a plurality of driving parts 222. The screen plate 221 is movably installed in the cavity 1a via an elastic member. The plurality of driving parts 222 are all installed on the modified cylinder 1 and connected to the screen plate 221. The driving parts 222 are used to drive the screen plate 221 to vibrate. The screen plate 221 has the screening sections.
[0035] It is understood that the screen plate 221 can be driven to vibrate up and down by multiple drive units 222. Specifically, the elastic element includes a guide rod, a spring and a limiting block. One end of the guide rod is fixedly connected to the modified cylinder, the spring is sleeved on the guide rod, and the guide rod passes through the through hole on the screen plate 221. The lower surface of the screen plate 221 abuts against the spring, and the other end of the guide rod is fixedly connected to the limiting block. When the screen plate 221 slides relative to the guide rod, the upper surface of the screen plate 221 can abut against the limiting block.
[0036] It should be noted that the drive unit 222 is not limited to a specific structure. In one embodiment, the drive unit 222 includes a geared motor 222a and a cam 222b. The geared motor 222a is fixed to the outside of the modified cylinder 1. The output shaft of the geared motor 222a extends into the cavity 1a and is fixed to the cam 222b. The cam 222b abuts against the sieve plate 221.
[0037] In this specific embodiment, the cam 222b abuts against the lower surface of the sieve plate. When the geared motor 222a drives the cam 222b to rotate, it can drive the sieve plate to vibrate up and down. Under the action of vibration, the material can be dispersed into each modification zone through the sieve section.
[0038] In one embodiment, the spraying mechanism 3 further includes a liquid storage tank 32 and a liquid extraction component 33. The liquid storage tank 32 is connected to the spraying component via the liquid extraction component 33. The liquid storage tank 32 is used to hold the modifier. The spraying component 31 includes a plurality of spray pipes 311, which are all inserted into the cavity 1a. Each spray pipe 311 corresponds to the top of each of the modification zones. Each spray pipe 311 is provided with a plurality of nozzles 312 at intervals. The modifier can be atomized and sprayed into the modification zone through the nozzles 312.
[0039] It should be noted that the pumping unit 33 can pump the modifier contained in the storage tank 32 to the spraying unit, and spray it into each modification zone through multiple spraying units 31 and multiple nozzles.
[0040] Based on the above scheme, in order to further improve the mixing effect between the material and the modifier, a stirring mechanism 4 is specifically included. The stirring mechanism 4 includes a drive motor 41, a rotating shaft 42 and multiple blades 43. The drive motor 41 is fixed to the bottom of the modification cylinder 1, and the output end of the drive motor 41 passes through the cavity 1a and is fixedly connected to one end of the rotating shaft 42. The other end of the rotating shaft 42 extends to the bottom of the modification zone, and the multiple blades 43 are all fixedly connected to the rotating shaft 42.
[0041] It is understandable that by driving the rotating shaft 42 to rotate in the forward direction by the drive motor 41, multiple blades 43 can be driven to stir the material at the bottom of the cavity 1a, thereby making the material and the modifier fully mixed.
[0042] In addition, in one embodiment, the stirring mechanism 4 further includes a spiral blade 44, which is disposed in the cavity 1a and fixedly connected to the rotating shaft 42, and the spiral blade 44 corresponds to the discharge end 1c at the bottom of the modified cylinder 1.
[0043] It should be noted that when it is necessary to discharge the material in the cavity 1a, the rotating shaft 42 can be driven to rotate in the opposite direction by the drive motor 41, which can drive the spiral blade 44 to rotate and squeeze the material through the discharge end 1c. In addition, a discharge valve is provided on the discharge end 1c, which is used to open or close the discharge end 1c.
[0044] Based on the above scheme, in order to facilitate the crushing of agglomerated materials, a crushing mechanism 5 is specifically included. The crushing mechanism 5 includes a feeding hopper 51 and a crushing component 52. The feeding hopper 51 is installed on the top of the modified cylinder 1 and corresponds to the feeding end 1b. The crushing component 52 is installed on the feeding hopper 51 and is used to crush the lumpy materials.
[0045] It should be noted that the crushing component 52 is not limited to a specific type of mechanism; it is acceptable as long as it can crush blocky materials. No other limitations are imposed here.
[0046] In addition, based on the above scheme, in order to facilitate observation of the internal condition of the cavity, specifically, an observation window 1d is nested on the modified cylinder 1.
[0047] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
