Description

Technical Field

[0001] This utility model relates to the field of adhesive mixing technology, specifically to a heating and mixing device for producing adhesive for bonding steel. Background Technology

[0002] Steel bonding adhesive is an epoxy resin structural adhesive used in building reinforcement to bond steel plates to the surface of concrete components. Through high-strength bonding, the two form an integrated load-bearing structure, improving the load-bearing capacity of the component. It is widely used in the reinforcement of concrete structures such as beams and columns.

[0003] In the production of steel bonding adhesive, the raw materials need to be heated and stirred. In the existing technology, a mixing tank is usually used to heat and stir the raw materials, so that the raw materials become a gel-like primary steel bonding adhesive. However, when stirring the raw materials in the existing technology, the raw materials in the mixing tank can only be rotated in a fixed direction, which cannot achieve mixing at different levels, resulting in insufficient mixing, affecting the mixing quality of the materials. At the same time, it is not convenient to discharge the primary steel bonding adhesive in the mixing tank for subsequent processing. Utility Model Content

[0004] The purpose of this invention is to provide a heating and stirring device for producing steel bonding adhesive, which solves the problem in the prior art that when stirring raw materials, different levels of mixing cannot be achieved, resulting in insufficient mixing, affecting the quality of material mixing, and making it inconvenient to discharge the primary steel bonding adhesive in the mixing tank for subsequent processing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A heating and stirring device for producing steel bonding adhesive includes a stirring tank with supporting feet at the bottom and a cover plate on the top side of the tank. A feeding port is provided through the cover plate. A discharge pipe is provided at the bottom of the stirring tank with a valve. A through cylinder with its central axis coinciding with the central axis of the discharge pipe is located inside the stirring tank. The bottom end of the through cylinder is fixedly connected to the bottom side of the stirring tank via connectors arranged in a ring array. A servo motor is provided on the top side of the cover plate. The output shaft of the servo motor rotates through the cover plate and is placed inside the stirring tank. It is connected to a rotating rod arranged along the central axis of the through cylinder and the discharge pipe. A spiral blade is sleeved on the outside of the rotating rod. A crossbar is provided at the top of the rotating rod, and vertical stirring rods are provided at both ends of the crossbar.

[0006] A further technical solution is to have multiple sets of through holes opened on the outer side wall of the through cylinder along its central axis, with each set of through holes arranged in a ring array around the side wall of the through cylinder.

[0007] A further technical solution is that the stirring rod is connected to an outer scraper and an inner scraper via a support rod. The outer scraper slides against the inner wall of the mixing tank, and the inner scraper slides against the outer wall of the through-tube.

[0008] A further technical solution is to install a sealing cap on the feeding port.

[0009] A further technical solution includes a controller, an electric heating wire wound and embedded in the side wall of the mixing tank, a temperature sensor embedded in the inner wall of the mixing tank, and the temperature sensor, the electric heating wire and the servo motor are all electrically connected to the controller.

[0010] Compared with the prior art, the beneficial effects of this utility model are: In use, this invention features spiral blades. When raw materials enter the bottom of the through-tube through the gap between the connectors, the rotating spiral blades push the raw materials along the through-tube towards the top. The raw materials in the through-tube overflow from the top and are placed above the raw materials in the mixing tank. Simultaneously, the rotating stirring rod stirs the raw materials between the through-tube and the mixing tank. This process is repeated to achieve different levels of mixing in the mixing tank, ensuring a good mixing effect. During discharge, the servo motor drives the spiral blades to rotate in the opposite direction, pushing the primary steel-adhesive adhesive in the through-tube and discharge pipe out through the discharge pipe. At the same time, the primary steel-adhesive adhesive between the through-tube and the mixing tank flows into the top of the discharge pipe through the gap between the connectors under the action of gravity, and is finally discharged through the discharge pipe under the push of the spiral blades, accelerating the discharge efficiency of the primary steel-adhesive adhesive for subsequent production.

Detailed Implementation

[0014] 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 merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] Example 1 Reference Figure 1 , Figure 2This utility model discloses a heating and stirring device for producing steel adhesive, comprising a stirring tank 1, a supporting foot 2 at the bottom of the stirring tank 1, a cover plate 3 on the top side of the stirring tank 1, a feeding port through the cover plate 3, a discharge pipe 4 at the bottom of the stirring tank 1, a valve 5 on the discharge pipe 4, a through cylinder 6 inside the stirring tank 1 whose central axis coincides with the central axis of the discharge pipe 4, the bottom end of the through cylinder 6 being fixedly connected to the bottom side inside the stirring tank 1 by connecting pieces 7 arranged in a ring array at intervals, so that there is a gap between the through cylinder 6 and the bottom side inside the stirring tank 1, and there is also a gap between two adjacent connecting pieces 7, a servo motor 8 is provided on the top side of the cover plate 3, the output shaft of the servo motor 8 is rotated through the cover plate 3 and placed inside the stirring tank 1, and is connected to a rotating rod 9 arranged along the central axis of the through cylinder 6 and the discharge pipe 4, a spiral blade 10 is sleeved on the outside of the rotating rod 9, a crossbar 11 is provided at the top of the rotating rod 9, and vertical stirring rods 12 are provided at both ends of the crossbar 11.

[0016] In this embodiment, during use, the raw material is injected into the mixing tank 1 through the feeding port. The servo motor 8 is controlled to work, driving the rotating rod 9 to rotate forward. The rotating rod 9 drives the spiral blade 10 and the stirring rod 12 to rotate. At this time, when the raw material enters the bottom of the penetrating cylinder 6 through the gap between the connecting parts 7, the rotating spiral blade 10 pushes the raw material along the penetrating cylinder 6 towards the top of the penetrating cylinder 6, preventing the raw material from flowing into the discharge pipe 4 and failing to be fully stirred. The raw material entering the penetrating cylinder 6 finally overflows through the top of the penetrating cylinder 6 and is placed above the raw material in the mixing tank 1. Because the spiral blade 10 rotates forward and pushes the raw material along the penetrating cylinder 6 towards the top of the penetrating cylinder 6, the raw material between the penetrating cylinder 6 and the mixing tank 1 will move downwards. Near the bottom of the through-tube 6, the stirring rod 12 rotates to stir the raw materials between the through-tube 6 and the mixing tank 1. This process is repeated to achieve different levels of mixing of the raw materials in the mixing tank 1, ensuring the mixing effect. When the raw materials are stirred into a gel-like primary steel-adhesive, the valve 5 is opened, and the servo motor 8 is controlled to drive the spiral blade 10 to rotate in the opposite direction, pushing the primary steel-adhesive in the through-tube 6 and the discharge pipe 4 to be discharged through the discharge pipe 4. At the same time, the primary steel-adhesive between the through-tube 6 and the mixing tank 1 flows into the top of the discharge pipe 4 through the gap between the connecting parts 7 under the action of gravity. Finally, it is discharged through the discharge pipe 4 under the push of the spiral blade 10, which speeds up the discharge efficiency of the primary steel-adhesive to facilitate subsequent production.

[0017] Example 2 Based on the aforementioned Embodiment 1, referring to Figure 1 , Figure 2 The outer side wall of the through cylinder 6 has multiple sets of through holes 13 along its central axis, and each set of through holes 13 is arranged in a ring array around the side wall of the through cylinder 6.

[0018] In this embodiment, by setting through hole 13, as the spiral blade 10 rotates and pushes the raw material along the through cylinder 6 toward the top of the through cylinder 6, some raw material will overflow through through hole 13. Under the stirring action of stirring rod 12, it will be stirred with the raw material located between the through cylinder 6 and the mixing tank 1, further realizing the mixing of different levels and ensuring the stirring effect.

[0019] Example 3 Based on the aforementioned Embodiment 1, referring to Figure 1 , Figure 2 As shown, an outer scraper 14 and an inner scraper 15 are connected to the stirring rod 12 via a support rod 16. The outer scraper 14 slides against the inner wall of the mixing tank 1, and the inner scraper 15 slides against the outer wall of the through cylinder 6.

[0020] In this embodiment, by setting an inner scraper 15 and an outer scraper 14, the stirring rod 12 will drive the inner scraper 15 and the outer scraper 14 to rotate when it rotates. The outer scraper 14 rotates and slides against the inner wall of the mixing tank 1 to scrape and clean the inner wall of the mixing tank 1. The inner scraper 15 rotates and slides against the outer wall of the connecting cylinder 6 to scrape and clean the outer wall of the connecting cylinder 6, so as to prevent the raw materials from adhering to the inner wall of the mixing tank 1 and the outer wall of the connecting cylinder 6 when discharged.

[0021] Example 4 Based on the aforementioned Embodiment 1, referring to Figure 1 , Figure 2 As shown, a sealing cover 17 is provided on the feeding port, which can seal the feeding port by setting the sealing cover 17.

[0022] Example 5 Based on the aforementioned embodiment 1, a controller (not shown in the figure) is also included. The position of the controller can be installed according to the actual situation. An electric heating wire 18 is wound and embedded in the side wall of the mixing tank 1, and a temperature sensor is embedded in the inner wall of the mixing tank 1. The temperature sensor, the electric heating wire 18 and the servo motor 8 are all electrically connected to the controller.

[0023] In this embodiment, during use, the controller controls the electric heating wire 18 to heat the raw material. The temperature sensor detects the temperature in real time and transmits the signal to the controller. The controller adjusts the on / off state or power of the heating wire according to the set temperature, such as through PWM adjustment, so as to maintain temperature stability. At the same time, the controller can also be used to control the working state of the servo motor 8.

[0024] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
