Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for a composite admixture of special mortar with quantitative feeding. Background Technology

[0002] Composite admixtures are key to achieving specific functions in specialty mortars. Specialty mortars need to possess special functions such as waterproofing, decoration, corrosion resistance, heat insulation, radiation protection, sound absorption, and bonding. Composite admixtures play a crucial role in this process. For example, by adding specialty admixtures and composite fibers, the crack resistance of the mortar is significantly improved, reducing the risk of structural cracking. In humid or underwater environments, it can effectively resist water erosion, maintaining the integrity and stability of the structure. Composite admixtures help reduce production costs and promote green development. In the production process, cement production processes, lime production processes, and premixed mortar technology are integrated to form a new type of composite cementitious material that does not contain medium sand in premixed mortar. This saves on the amount of cement and lime and other major cementitious materials, while increasing the amount of solid waste. It is an effective way to save energy, reduce emissions, promote low-carbon environmental protection, and develop a circular economy. At the same time, it provides premixed mortar companies with a new type of composite cementitious material, simplifying the complicated batching process and the preparation of multi-component materials.

[0003] Specialty mortars have stringent performance requirements, needing to possess special functions such as waterproofing, heat insulation, and corrosion resistance. The proportion of composite admixtures directly affects the mortar performance. The feeding device can precisely control the addition amount of various admixtures to ensure accurate proportioning, thereby guaranteeing stable mortar performance and meeting different engineering needs. The performance of specialty mortars depends on the precise proportion of admixtures. If the discharge volume fluctuates, key indicators such as mortar strength, fluidity, and durability will deviate from the design values. In addition, the particle size and density of admixtures vary greatly. If they are not mixed in advance, it will cause the mortar to stratify or segregate, affecting fluidity and water retention. For example, mineral powder has a high density and is prone to sedimentation at the bottom when not mixed, resulting in insufficient fluidity of the upper mortar. Additional water needs to be added during construction, further reducing strength. Utility Model Content

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0025] Example 1:

[0026] Reference Figures 1-4 This is the first embodiment of the present invention. This embodiment provides a composite admixture feeding device for quantitative feeding of special mortar, including a mounting frame 1 and a mixing chamber 2. The top of the mounting frame 1 is fixedly connected to the mixing chamber 2. A mixing component 3 is provided on the outside of the mixing chamber 2. A discharge pipe 4 is connected to the bottom of the mixing chamber 2. A discharge component 5 is provided on the outside of the discharge pipe 4. Two sets of limiting frames 6 are rotatably connected to the outside of the discharge pipe 4. Pressure sensors 7 are installed on the inner walls of both sets of limiting frames 6.

[0027] Mounting bracket 1 provides a support point for the installation of mixing chamber 2, which in turn provides space for mixing special mortar. Mixing component 3 mixes the mortar before discharge. Composite admixtures are typically composed of multiple components such as mineral powder, silica fume, and fly ash. If they are not mixed, the components will be unevenly distributed in the mortar, resulting in local performance differences. Discharge component 5 facilitates the discharge of the mixed raw materials. Pressure sensor 7 can determine the opening and closing time of limit frame 6 through a set threshold, thereby facilitating the quantitative discharge of mortar. Some technical solutions and working principles of pressure sensor 7 are existing technologies. As those skilled in the art will clearly understand, the resistance strain gauge of the pressure sensor 7 is one of the main components of the piezoresistive strain sensor. When the strain gauge is subjected to pressure, its resistance value will change. This change is connected to the Wheatstone bridge through the leads. When the sensor is compressed, the chip resistance changes, the bridge will lose balance, and output a voltage signal corresponding to the pressure. It should be noted that the principle of the pressure sensor 7 is the same as the principle of the pressure device in the aluminum molten aluminum feeding device for aluminum rod production with quantitative feeding function in the authorized application number CN110947943B. It will not be elaborated further here.

[0028] A feed frame 12 is installed on the outside of the mixing chamber 2, and a support rod 13 for supporting the two sets of connecting frames 32 is fixedly connected to the inner wall of the connecting frame 32.

[0029] A limiting plate 14 is slidably connected to the inner wall of the mixing chamber 2. A pull rod 15 is fixedly connected to the outer side of the limiting plate 14. An insertion rod 16 is inserted into the outer side of the mixing chamber 2, and the outer side of the insertion rod 16 is inserted into the inner wall of the limiting plate 14. A limiting strip 17 is fixedly connected to the inner wall of the limiting plate 14, and the outer side of the limiting strip 17 is slidably connected to the inner wall of the mixing chamber 2.

[0030] Example 2:

[0031] This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, the mixing component 3 includes a drive unit 31 installed on the outside of the mixing chamber 2, a connecting frame 32 is provided on the outside of the drive unit 31, and a mixing plate 33 is fixedly connected to the inner wall of the connecting frame 32.

[0033] The drive unit 31 provides power for the rotation of the connecting frame 32 and the mixing plate 33. The cooperation between the connecting frame 32 and the mixing plate 33 facilitates the uniform mixing of raw materials in the mixing chamber 2.

[0034] Specifically, the discharge assembly 5 includes a pusher 51 disposed on the outside of the discharge pipe 4, a connecting rod 52 disposed at the bottom of the pusher 51, a connecting block 53 fixedly connected to the bottom of the connecting rod 52, and the inner wall of the connecting block 53 slidably connected to the outer side of the limiting frame 6.

[0035] The pusher 51 can easily drive the connecting rod 52 to move vertically, and the connecting rod 52 can drive the connecting block 53 to move vertically, thereby facilitating the opening and closing of the limiting frame 6, and thus facilitating the discharge of the uniformly mixed raw materials.

[0036] Specifically, the drive unit 31 includes a motor 311 fixedly connected to the top of the mixing chamber 2, and a mounting rod 312 fixedly connected to the output end of the motor 311, and the outer side of the mounting rod 312 is fixedly connected to the inner wall of the connecting frame 32.

[0037] The motor 311 can drive the mounting rod 312 to rotate, the mounting rod 312 drives the connecting frame 32 to rotate, and the connecting frame 32 drives the mixing plate 33 to rotate, thereby mixing the raw materials in the mixing chamber 2.

[0038] Specifically, the pusher 51 includes a cylinder 511 installed on the outside of the discharge pipe 4. The piston rod of the cylinder 511 is fixedly connected to a mounting ring 512, and the inner wall of the mounting ring 512 is slidably connected to the outside of the discharge pipe 4.

[0039] Cylinder 511 can drive mounting ring 512 to move vertically. Mounting ring 512 can drive connecting rod 52 and connecting block 53 to move vertically, thereby facilitating the opening and closing of limit frame 6 and facilitating the discharge of raw materials. It should be noted that cylinder 511 is composed of an air compressor, air tank, filter pressure reducing valve, directional control valve and flow control valve. In use, the air compressor compresses ambient air to a set pressure and stores it in the air tank. The filter pressure reducing valve further purifies the air and stabilizes the pressure, and delivers it to the control valve through the air pipe. The directional control valve switches the airflow channel according to the electrical signal to determine the extension and retraction direction of cylinder 511. The flow control valve adjusts the airflow speed and controls the movement speed of cylinder 511. Compressed air enters the rodless chamber or rodless chamber of cylinder 511, pushing the piston to move. The piston drives the piston rod to output linear reciprocating motion.

[0040] Specifically, the top of the mounting frame 1 is fixedly connected to a support frame 8 for improving the stability of the discharge pipe 4, and the inner wall of the support frame 8 is slidably connected to the outer side of the connecting rod 52. The inner wall of the support frame 8 is slidably connected to a limit rod 9, and the top of the limit rod 9 is fixedly connected to the bottom of the mounting ring 512.

[0041] The support frame 8 can support the discharge pipe 4 and also facilitates the use of the limiting rod 9 to limit the installation ring 512, thereby improving the stability of the installation ring 512 during the sliding process.

[0042] Specifically, a fixing rod 10 is fixedly connected to the outer side of the limiting frame 6, and a limiting groove 11 for limiting the fixing rod 10 is provided on the inner wall of the connecting block 53.

[0043] The cooperation between the fixed rod 10 and the limiting groove 11 facilitates the vertical movement of the limiting groove 11 when the connecting block 53 and the connecting rod 52 move vertically. This causes the fixed rod 10 to slide along the inner wall of the limiting groove 11, thereby causing the limiting frame 6 to rotate and thus completing the opening and closing of the limiting frame 6.

[0044] Example 3:

[0045] This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, a feed frame 12 is installed on the outside of the mixing chamber 2, and a support rod 13 for supporting the two sets of connecting frames 32 is fixedly connected to the inner wall of the connecting frame 32.

[0047] The feed frame 12 can feed raw materials into the mixing chamber 2, and the support rod 13 can support the two sets of connecting frames 32, thereby improving the stability of the connecting frames 32 when rotating.

[0048] Specifically, a limiting plate 14 is slidably connected to the inner wall of the mixing chamber 2, a pull rod 15 is fixedly connected to the outer side of the limiting plate 14, an insertion rod 16 is inserted into the outer side of the mixing chamber 2, and the outer side of the insertion rod 16 is inserted into the inner wall of the limiting plate 14. A limiting strip 17 is fixedly connected to the inner wall of the limiting plate 14, and the outer side of the limiting strip 17 is slidably connected to the inner wall of the mixing chamber 2.

[0049] The limiting plate 14 can limit the raw materials during the mixing process to prevent them from falling into the discharge pipe 4. The pull rod 15 can easily pull the limiting plate 14 to release the limit after the raw materials are mixed. The plug rod 16 can limit the limiting plate 14 to prevent it from loosening during mixing. The limiting strip 17 can prevent the raw materials from leaking out of the gap between the mixing chamber 2 and the limiting plate 14 when the limiting plate 14 is pulled.

[0050] In use, first, feed the raw material into the feed box 12, then start the motor 311. The motor 311 drives the mounting rod 312 to rotate, which in turn drives the connecting frame 32 to rotate. The connecting frame 32 then drives the mixing plate 33 to rotate, thereby mixing the raw material in the mixing chamber 2. Then, pull out the plug rod 16 to release the limit plate 14. Next, hold the pull rod 15, which will move the limit plate 14 horizontally. Note that the pulling distance should not exceed the length of the limit strip 17. At this time, the rotation of the connecting frame 32 will scrape the raw material off the surface of the limit plate 14, thus mixing the raw material in the mixing chamber 2 and the limit plate 14. The material falls into the discharge pipe 4 through the gap between the two. At this time, when the pressure sensor 7 reaches the predetermined threshold, the cylinder 511 will be activated. The cylinder 511 drives the mounting ring 512 to move vertically. The mounting ring 512 can drive the connecting rod 52 and the connecting block 53 to move vertically, thereby driving the limiting groove 11 to move vertically. The limiting groove 11 squeezes the fixing rod 10, forcing the fixing rod 10 to slide along the inner wall of the limiting groove 11, thereby driving the limiting frame 6 to rotate, thus completing the opening and closing of the limiting frame 6. At this time, the material can be discharged. When the opening and closing time of the limiting frame 6 reaches the predetermined threshold, the cylinder 511 will pull back again, thereby completing the quantitative feeding.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
