Description

Technical Field

[0001] This utility model relates to the field of calcium carbide furnace feeding and dust removal technology, specifically an interlocking control device for calcium carbide furnace feeding system and dust removal system. Background Technology

[0002] In the production of calcium carbide furnaces, the feeding system needs to continuously deliver raw materials into the furnace. During the turnover and transportation of materials in the hopper, a large amount of dust is easily generated. If it is not dealt with in time, it will cause environmental pollution in the workshop and may also affect the normal operation of equipment and the health of operators. Therefore, a dust removal system is required to control the dust.

[0003] However, traditional feeding systems and dust removal systems are mostly operating in relatively independent modes. The dust removal system usually maintains a fixed operating state, making it difficult to dynamically adjust the operating parameters according to the actual material conveying situation of the feeding system. This results in high energy consumption even when high-intensity dust removal is not required, or in untimely dust removal when the amount of dust generated increases sharply. It is difficult to balance environmental protection requirements and operating economy. Therefore, there is an urgent need for an interlocking control device for the calcium carbide furnace feeding system and dust removal system to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 - Figure 6 The interlocking control device for the calcium carbide furnace charging system and dust removal system provided by this utility model includes a mounting frame 1. A charging channel 2 is fixedly connected to the side wall of the mounting frame 1. A connecting channel 3 is fixedly connected to the bottom surface of the charging channel 2. A dust removal channel 4 is fixedly connected to the side wall of the connecting channel 3. Two dust removal fans 5 are fixedly connected to the inner wall of the dust removal channel 4. The interlocking control device for the calcium carbide furnace charging system and dust removal system also includes:

[0025] Interlocking control component, which is located on the bottom surface of the connecting channel 3, is used to trigger real-time physical sensing when the calcium carbide furnace is being fed;

[0026] A proximity conversion component is disposed on the side wall of the communication channel 3 and is used to convert the proximity method of physical sensing.

[0027] The interlocking control components facilitate the triggering of real-time physical sensing during the feeding of the calcium carbide furnace, thereby controlling the subsequent dust removal system to make an interlocking control response. The proximity conversion components facilitate the conversion of the physical sensing proximity method, thereby improving the stability of the linkage control. In this application, the dust removal fan 5 is a common dust and air conveying component, equipped with an integrated motor as the power drive for the dust removal fan 5. The dust removal fan 5 is prior art in this application and will not be described in detail here.

[0028] Furthermore, the interlocking control assembly includes a trigger hopper 601, which is disposed on the bottom surface of the connecting channel 3. A rotating column 602 is fixedly connected to the inner wall of the trigger hopper 601. Two fixed blocks 603 are rotatably connected to the surface of the rotating column 602. The side walls of the two fixed blocks 603 are fixedly connected to both sides of the connecting channel 3, respectively. A trigger plate 608 is fixedly connected to the side wall of the trigger hopper 601. A fixing frame 609 is fixedly connected to the side wall of the connecting channel 3. A proximity sensor 610 is disposed on the inner wall of the fixing frame 609. A controller 612 is fixedly connected to the side wall of the connecting channel 3. The proximity sensor 610 is electrically connected to the controller 612. The controller 612 is electrically connected to the drive motor of the dust removal fan 5. The two sides of the connecting channel 3 are open. An arc-shaped embedding hole 604 is provided, and a fixing strip 605 is slidably connected to the inner wall of the arc-shaped embedding hole 604. The bottom surfaces of both fixing strips 605 are fixedly connected to the top surface of the trigger hopper 601. Connecting blocks 606 are fixedly connected to both sides of the connecting channel 3. An arc-shaped spring 607 is provided on the inner wall of the arc-shaped embedding hole 604. The lower end of the arc-shaped spring 607 is fixedly connected to the top surface of the connecting block 606, and the upper end of the arc-shaped spring 607 is fixedly connected to the fixing strip 605. Two fixing nuts 611 are threadedly connected to the surface of the proximity sensor 610. One end of the fixing nut 611 abuts against the side wall of the fixing frame 609. Through the interlocking control component, when the material is fed through the mounting frame 1, the material falls into the trigger hopper 601 through the connecting channel 3. The surface of the material trigger hopper 601 is affected by the gravity of the material, causing it to rotate clockwise around the rotating column 602 under the constraint of the column 602. When the trigger hopper 601 rotates due to the gravity of the material, it drives the trigger plate 608 to move, thus changing the distance between the trigger plate 608 and the proximity sensor 610 with the gravity of the plastic material. The more material falls onto the surface of the trigger hopper 601, the closer the distance between the sliding hole 702 and the proximity sensor 610 becomes, and vice versa. At the same time, the proximity sensor 610 is electrically connected to the controller 612, so that the proximity sensor 610 converts the distance between the trigger plates 608 into a digital signal and transmits the digital signal to the controller 612. The controller 612 then controls the movement of the material. The drive motor of the dust removal fan 5 controls the real-time speed of the dust removal fan 5, thereby achieving dynamic linkage between the feeding system and the dust removal system, achieving a balance between environmental protection and economy. The arc-shaped embedding hole 604, the fixing strip 605, and the arc-shaped spring 607 work together to facilitate the reset of the trigger hopper 601. The arc-shaped spring 607 is located on the inner wall of the arc-shaped embedding hole 604, facilitating its limiting and improving its stability during use. The connecting block 606 provides stable support for the arc-shaped spring 607, further enhancing its stability. The fixing nut 611...This facilitates the adjustment and fixing of the position of the proximity sensor 610.

[0029] Furthermore, the proximity conversion assembly includes a conversion frame 701, which is fixedly connected to the side wall of the connecting channel 3. A sliding hole 702 is provided on the inner wall of the conversion frame 701. A sensing sliding frame 703 is slidably connected to the inner wall of the sliding hole 702. A compression spring 704 is fixedly connected to the side wall of the sensing sliding frame 703, and the other end of the compression spring 704 is fixedly connected to the inner wall of the conversion frame 701. The side wall of the trigger plate 608 abuts against the side wall of the sensing sliding frame 703. Through the proximity conversion assembly, the trigger plate 608 moves, pushing the sensing sliding frame 703. The movable compression spring 704 retracts, and the sensing sliding frame 703 is arranged parallel to the proximity sensor 610. This facilitates the conversion of the wedge-shaped approach of the trigger plate 608 into a linear approach between the sensing sliding frame 703 and the proximity sensor 610 under the push of the trigger plate 608. This parallel linear approach improves the stability of the signal detection of the proximity sensor 610. The cooperation between the proximity sensor 610 and the sensing sliding frame 703 facilitates accurate detection of the material on the surface of the trigger hopper 601, thereby improving the stability of the linkage control.

[0030] Working principle: During use, through the interlocking control components, when material is fed through the mounting frame 1, it falls onto the surface of the trigger hopper 601 via the connecting channel 3. Affected by the weight of the material, the trigger hopper 601 rotates clockwise around the rotating column 602 under the constraint of the rotating column 602. As the trigger hopper 601 rotates under the weight of the material, it causes the trigger plate 608 to shift, thus changing the distance between the trigger plate 608 and the proximity sensor 610 according to the weight of the plastic material. When the material falls onto the surface of the trigger hopper 601... The more material on the surface, the closer the distance between the sliding hole 702 and the proximity sensor 610, and vice versa. At the same time, the proximity sensor 610 is electrically connected to the controller 612, so that the proximity sensor 610 converts the distance between the trigger plates 608 into a digital signal and transmits the digital signal to the controller 612. The controller 612 controls the drive motor of the dust removal fan 5, thereby controlling the real-time speed of the dust removal fan 5, and thus realizing dynamic linkage between the feeding system and the dust removal system, achieving a balance between environmental protection and economy.

[0031] Meanwhile, the proximity conversion component causes the trigger plate 608 to move and push the induction sliding frame 703 to move, compressing the spring 704. The induction sliding frame 703 is parallel to the proximity sensor 610, so that the induction sliding frame 703 and the proximity sensor 610 approach each other in a straight line under the push of the trigger plate 608. This parallel straight-line approach improves the stability of the proximity sensor 610 signal detection. The cooperation between the proximity sensor 610 and the induction sliding frame 703 facilitates accurate detection of materials on the surface of the trigger hopper 601, thereby improving the stability of the linkage control.
