Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a reaction vessel for the production of industrial cleaning agents. Background Technology

[0002] In industrial production, reaction vessels are key equipment used to complete processes such as mixing and reacting materials. In the production of industrial cleaning agents, it is usually necessary to add various solid or liquid raw materials into the reaction vessel in a certain order and proportion, and carry out stirring, mixing and chemical reaction to obtain a uniform and effective cleaning agent product.

[0003] Currently, common reaction vessels typically include a vessel body, a stirrer, and a heating device. During production, the main raw materials are first added to the vessel and stirred. Then, other auxiliary raw materials or reactants are added sequentially through the feed pipe while stirring. However, this simple feeding method has several drawbacks: First, for materials that need to be added in stages and in precise quantities, especially solid materials, it is easy to add too much or too quickly at once, leading to excessively high local concentrations, incomplete reactions, or the formation of byproducts, affecting product quality. Second, the added materials may clump or be unevenly dispersed, requiring a longer stirring time to achieve uniform mixing. Finally, after the reaction is complete, the product may contain unreacted clumps or impurities, usually requiring additional filtration equipment or steps for subsequent processing, increasing production processes and equipment costs, and reducing production efficiency.

[0004] Therefore, there is a lack of an integrated reaction device in the existing technology that can achieve controlled addition of materials, efficient mixing, and online filtration of the final product. Utility Model Content

[0005] To address the technical deficiencies in the background technology, this utility model proposes a reaction vessel for the production of industrial cleaning agents, which solves the aforementioned technical problems and meets practical needs.

The reaction vessel body contains: The power assembly includes a drive motor and a rotating shaft. The drive motor is fixed to the upper end of the reactor body, and the output end of the drive motor extends downward into the interior of the reactor body. The upper end of the rotating shaft is fixedly connected to the output end of the drive motor.

The filter plate has its upper end fixedly connected to the rotating shaft, and has several filter holes. The side of the filter plate is slidably connected to the main body of the reactor.

[0006] As a further technical solution of this utility model, the part of the rotating shaft located between the stirring assembly and the filter plate is provided with a bushing. The bushing is fixedly connected to the main body of the reactor through a fixing frame. The bushing is slidably connected to the rotating shaft and to the feeding assembly.

The storage ring has several feeding holes, and a feeding hopper is provided at the lower end of each feeding hole. The rebound assembly is located in the middle of the storage ring.

[0008] As a further technical solution of this utility model, the rebound assembly includes a rotating wheel, a fixed wheel, a connecting shaft, a spring, and a baffle plate. The rotating wheel and the portion of the rotating shaft located inside the storage ring are fixedly connected. The rotating wheel and the storage ring are slidably connected. An arc-shaped first cam is provided on one side of the lower end of the rotating wheel. The fixed wheel is located below the rotating wheel.

Detailed Implementation

[0016] The embodiments of this utility model will be described below with reference to the accompanying drawings and related examples. The embodiments of this utility model are not limited to the following examples, and this utility model relates to relevant necessary components in this technical field, which should be regarded as well-known technology in this technical field and can be known and mastered by those skilled in this technical field.

[0017] like Figures 1 to 10 As shown, a reaction vessel for the production of industrial cleaning agents includes a reaction vessel body 1. A feed pipe 2 is connected to the upper end of the side wall of the reaction vessel body 1. The feed pipe 2 is fixedly connected to the reaction vessel body 1 via a flange in an upward-sloping manner for the input of reaction raw materials. A discharge pipe 3 is connected to the lower end of the reaction vessel body 1. The discharge pipe 3 is fixedly connected to the reaction vessel body 1 via a flange in a downward-sloping manner for the collection of the finished product. Multiple support legs 4 are detachably provided at the bottom of the reaction vessel body 1 via bolts. The support legs 4 can be telescopic or foldable supports to save storage space.

[0018] like Figures 1 to 10 As shown, a power assembly 5, a stirring assembly 6, a feeding assembly 7, and a filter plate 8 are arranged inside the reactor body 1. The power assembly 5 includes a drive motor 51 and a rotating shaft 52. The upper end of the drive motor 51 is detachably mounted on the upper surface of the reactor body 1 by bolts, facilitating subsequent disassembly for maintenance. The output end of the drive motor 51 faces downward and extends into the reactor body 1. A vertical rotating shaft 52 is fixedly connected to the output end of the drive motor 51 in a nested manner, thereby transmitting the power of the drive motor 51 to the rotating shaft 52 to provide power to the entire device. A stirring assembly 6, including several stirring paddles 61, is arranged in the upper half of the rotating shaft 52. The stirring paddles 61 are distributed along the circumference and axial direction of the rotating shaft 52 to stir and mix the raw materials in the device. Below the stirring assembly 6, a feeding assembly 7 is fixedly connected to the side wall of the reactor body 1. A through-hole channel is opened in the middle of the feeding assembly 7, through which the rotating shaft 52 continues to extend downward. At the bottom of the rotating shaft 52, a circular filter plate 8 is fixedly connected. The side of the filter plate 8 is slidably connected to the inner wall of the reactor body 1 with a clearance fit, so that the filter plate 8 can rotate with the rotating shaft 52. A large number of tiny filter holes 81 are evenly opened on the filter plate 8 to intercept solid particles that are not completely dissolved or require a specific particle size, ensuring that only the required mixture can enter the lower layer.

[0019] like Figures 1 to 10As shown, a bushing 11 is fitted onto the portion of the rotating shaft 52 located between the stirring assembly 6 and the filter plate 8. This bushing 11 is bolted to the inner wall of the reactor body 1 via a radially oriented fixing bracket 12. The fixing bracket 12 is made of high-strength alloy and has a small diameter, so it does not affect the mixing and falling of raw materials within the device. The rotating shaft 52 passes through the bushing 11 and is slidably connected to the inner wall of the bushing 11 via a bearing. Simultaneously, the bushing 11 is also slidably connected to the central channel wall of the feeding assembly 7.

[0020] like Figures 1 to 10 As shown, the feeding assembly 7 mainly includes an annular storage ring 71 fixedly embedded in the middle of the reactor body 1 and a rebound assembly 74 vertically arranged in the center of the storage ring 71. The upper cavity of the storage ring 71 can be used to temporarily store some solid raw materials or additives that need to be added in stages. Several feeding holes 72 are evenly opened along the circumference at the bottom of the storage ring 71, and a funnel-shaped feeding hopper 73 is fixedly connected to the lower end of each feeding hole 72 to guide the material to fall. The rebound assembly 74 controls the opening and closing of the outlet of the feeding hopper 73 through its special structure.

[0021] like Figures 1 to 10As shown, the rebound assembly 74 includes a rotating wheel 741, a fixed wheel 743, a connecting shaft 745, a spring 748, and a baffle plate 746. The rotating wheel 741 is fixedly connected to the portion of the rotating shaft 52 located inside the storage ring 71, and the rotating wheel 741 is slidably connected to the storage ring 71, allowing the rotating wheel 741 to rotate with the rotating shaft 52. A first arc-shaped cam 742 is provided on one side of the lower end of the rotating wheel 741. The fixed wheel 743 is located below the rotating wheel 741, and a second cam 744 that cooperates with the first cam 742 is provided on the upper end of the fixed wheel 743. The lower end of the first cam 742 contacts the fixed wheel 743, and the upper end of the second cam 744 contacts the rotating wheel 741. A connecting shaft 745 is fixed to the lower end of the fixed wheel 743, and a baffle plate 746 is fixed to the lower end of the connecting shaft 745. The baffle plate 746 has several plugs 747 that cooperate with the discharge port of the hopper 73. The baffle plate 746 is radiating outwards from the center. A spring 748 is sleeved on the connecting shaft 745. The upper end of the spring 748 is fixedly connected to the storage ring 71, and the lower end of the spring 748 is fixedly connected to the baffle plate 746. The working process of the rebound assembly 74 is as follows: the drive motor 51 drives the rotating shaft 52 and the rotating wheel 741 fixed thereon to rotate. When the first cam 742 on the lower surface of the rotating wheel 741 contacts the protruding part of the second cam 744 on the upper surface of the fixed wheel 743, the fixed wheel 743 is pushed upward, and the baffle plate 746 moves upward through the connecting shaft 745, compressing the spring 748. At this time, the plug 747 on the baffle plate 746 tightly blocks the discharge port of the feeding hopper 73, stopping the feeding. As the rotating wheel 741 continues to rotate, the protruding parts of the first cam 742 and the second cam 744 disengage. Under the restoring force of the spring 748, the fixed wheel 743, the connecting shaft 745 and the baffle plate 746 move downward as a whole, and the plug 747 leaves the discharge port of the feeding hopper 73, realizing the addition of material. This cycle is repeated to achieve periodic and controllable feeding, so that the product at the top of the device can fall onto the filter plate 8 in a quantitative manner, and it is not easy to accumulate, thereby affecting the quality and efficiency of filtration.

[0022] like Figures 1 to 10 As shown, one or more radially extending scrapers 16 are installed at the lower end of the bushing 11. The lower edge of the scraper 16 is in close contact with the upper surface of the filter plate 8. Meanwhile, an annular grooved band 82 is provided around the outer circumference of the filter plate 8. Large-diameter particles or impurities remaining on the upper surface of the filter plate 8 after filtration are scraped into the grooved band 82 by the scraper 16 through centrifugal force during the rotation of the filter plate 8, preventing them from clogging the filter holes 81 and ensuring the quality and efficiency of filtration.

[0023] like Figures 1 to 10As shown, a hollow jacket 13 is provided inside the side wall of the reactor body 1. A heater 14 is installed inside the jacket 13. The heater 14 can use a heating rod or heating belt to provide a suitable reaction temperature for the device.

[0024] like Figures 1 to 10 As shown, the lower end of the reactor body 1 is connected to an inverted conical discharge hopper 15, and the lower opening of the discharge hopper 15 is fixedly connected to the discharge pipe 3 by means of a flange connection.

[0025] like Figures 1 to 10 As shown, a valve 31 is installed on the discharge pipe 3, which can be a ball valve or a butterfly valve, to control the discharge and shut-off of materials. At the upper end of the feed pipe 2, a flared feed hopper 21 is detachably connected via a flange, which facilitates feeding and prevents material waste.

[0026] The specific workflow is as follows: First, the raw materials are fed into the reactor body 1 through the feed pipe 2 and feed hopper 21; the drive motor 51 is started, driving the rotating shaft 52 and the upper stirring paddle 61 to rotate at high speed, fully shearing and mixing the raw materials. Subsequently, the mixture flows through the feeding assembly 7, where the solid additives in the storage ring 71 are automatically and intermittently fed under the periodic action of the cam mechanism rotating with the rotating shaft 52. The material continues to flow downward to the rotating filter plate 8 driven by the rotating shaft 52. Under the action of centrifugal force, the required liquid and fine particles pass through the filter holes 81, while undissolved solid particles are retained. At the same time, the scraper 16 fixed at the lower end of the bushing 11 continuously scrapes off the filter residue to prevent clogging. During this process, the heater 14 in the jacket 13 can provide a suitable temperature for the reaction as needed. Finally, the finished product, after mixing and filtration, is collected under the guidance of the inverted conical discharge hopper 15 and discharged controllably through the discharge pipe 3 equipped with a valve 31.

[0027] This invention significantly improves production efficiency and product quality by integrating powered stirring, intermittent feeding, and dynamic filtration. It utilizes a combination of a rotating filter plate 8 and a fixed scraper 16 to achieve online self-cleaning of the filter surface, effectively solving the problem of filter pore clogging and ensuring continuous production. A clever cam rebound mechanism enables automatic and controllable feeding of solid materials without additional power, improving process flexibility. The intermediate bushing 11 enhances the stability of the rotating shaft 52 and extends the equipment's lifespan. The heating jacket 13 and the conical discharge hopper 15 further optimize reaction conditions and material yield. The entire device is compact and functionally synergistic, achieving continuous and automated mixing, reaction, and separation in the production of industrial cleaning agents.

[0028] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
