Description

Technical Field

[0001] This utility model relates to the field of chemical technology, specifically a chemical safety feeding device. Background Technology

[0002] Chemical industry, also known as chemical production, refers to the technology of altering the composition and structure of substances or synthesizing new substances using chemical methods. The resulting products are called chemicals or chemical products. Feeding is a crucial step in chemical production. Traditional feeding methods often rely on manual labor or simple mechanical equipment. While these methods can meet production needs to some extent, they still present safety hazards and operational inconveniences. For example, traditional feeding methods often depend on direct worker operation, increasing the risk of workers being exposed to harmful chemicals and potentially leading to health problems or accidents caused by operational errors. Furthermore, prolonged exposure to chemical raw materials poses a potential threat to workers' health. Moreover, most existing feeding equipment is difficult to control precisely, easily leading to overfeeding or underfeeding, which in turn affects production efficiency and product quality. Therefore, we propose a chemical safety feeding device to address these issues. Utility Model Content

[0003] The purpose of this invention is to provide a chemical safety feeding device to solve the problems mentioned in the background art, such as the increased risk of workers being exposed to harmful chemicals due to their proximity to the reactor and the difficulty in accurately controlling the amount of feed.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a chemical safety feeding device, comprising:

[0005] Mounting frame, with a staircase on one side;

[0006] A crossbar is fixedly installed on the middle of both sides of the mounting frame, and a fixing ring is fixedly installed on the inner side of the crossbar;

[0007] A movable plate is mounted on the top of the mounting frame, and a storage tank is fixedly mounted on the top of the movable plate.

[0008] A feeding mechanism is disposed on the top of the mounting frame;

[0009] A metering mechanism is disposed inside the movable plate.

[0010] Preferably, the mounting frame has a reaction vessel inside, which is embedded in the fixing ring. The top of the reaction vessel is equipped with a sealing cap, and the top of the sealing cap is fixedly equipped with a feed inlet. The reaction vessel is fixed by the fixing ring, making the reaction vessel more stable.

[0011] Preferably, the feeding mechanism includes a slider, which is fixedly installed on both sides of the movable plate. The inner walls of the top two sides of the mounting frame are provided with sliding grooves, and the slider is embedded in the sliding grooves and slidably connected to the sliding grooves. A sliding rod is fixedly installed on one side of the top of the mounting frame and passes through the movable plate. A screw is installed on the other side of the top of the mounting frame through a bearing, and the screw passes through the movable plate through a thread. One end of the screw passes through one side of the top of the mounting frame and is fixedly installed with a rotating rod. A discharge port is fixedly installed at the bottom of the movable plate, and the discharge port, the movable plate and the storage tank are connected. The left and right movement of the movable plate can be controlled by the rotating rod, which is beneficial for safer feeding.

[0012] Preferably, the discharge port is funnel-shaped, and the bottom diameter of the discharge port is smaller than the top diameter of the inlet, which helps to make the feeding more accurate and prevents leakage and waste.

[0013] Preferably, the metering mechanism includes a slot located on the top side of the movable plate and connected to the interior of the movable plate. An insert plate is embedded inside the slot and slidably connected to the slot. A connecting block is fixedly installed on the top side of one side of the insert plate. A spring is fixedly installed on the bottom side of the storage tank, with two sets of springs (left and right). The other end of the spring is fixedly connected to the connecting block.

[0014] Preferably, one side of the insert plate is set as a semi-cylindrical shape, and the diameter of the semi-cylindrical side is larger than the diameter of the inner wall of the connecting hole, so that the connecting block can completely block the connecting hole.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows: This utility model;

[0016] By installing a movable plate, a storage tank, and a discharge port on the top of the mounting frame, and with a screw threaded through the movable plate and a slider embedded in the groove, when feeding is required, the material can be poured into the storage tank, and then the movable plate can be moved to one side by rotating the rotating rod. After the movable plate is moved to the position directly above the inlet, the material is poured into the sealed cover through the inlet. This increases the distance between the worker and the reactor, which helps prevent workers from coming into contact with harmful chemicals and improves safety.

[0017] By inserting a plate into the slot, and having a semi-cylinder on one side of the plate with a diameter larger than the diameter of the inner wall of the connecting hole, and in conjunction with a spring that is fixedly connected between the bottom of the storage tank and the connecting block, when the outlet is at the top of the inlet, the plate can be pulled outward to allow the material to fall into the reactor. By inserting the plate into the middle of the moving plate, the amount of material that can be loaded into the storage tank is fixed, thus ensuring that the amount of material added each time is the same.

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.

[0025] Example 1

[0026] like Figures 1 to 4 As shown, the present invention provides a chemical safety feeding device, comprising:

[0027] Mounting frame 1, with a staircase 7 on one side. Mounting frame 1 is made of steel, which has high strength and load-bearing capacity. The staircase 7 is made of wood, which has large mass and high stability. There will be no shaking when workers operate on the staircase 7.

[0028] The crossbar 2 is fixedly installed on the middle of both sides of the mounting frame 1, and a fixing ring 3 is fixedly installed on the inner side of the crossbar 2.

[0029] The movable plate 8 is installed on the top of the mounting frame 1, and the storage tank 9 is fixedly installed on the top of the movable plate 8.

[0030] The feeding mechanism is located on the top of the mounting frame 1. The feeding mechanism includes a slider 11, which is fixedly mounted on both sides of the movable plate 8. Slide grooves 12 are formed on the inner walls of both sides of the top of the mounting frame 1. The slider 11 is embedded in and slidably connected to the slide grooves 12. A sliding rod 13 is fixedly mounted on one side of the top of the mounting frame 1, and the sliding rod 13 passes through the movable plate 8. A screw 14 is mounted on the other side of the top of the mounting frame 1 via a bearing, and the screw 14 passes through the movable plate via a thread. 8. One end of the screw 14 passes through the top side of the mounting frame 1 and is fixedly mounted with a rotating rod 15. The bottom of the movable plate 8 is fixedly mounted with a discharge port 10, and the discharge port 10, the movable plate 8 and the storage tank 9 are connected. When the rotating rod 15 is rotated clockwise, the rotating rod 15 can drive the screw 14 to rotate clockwise, thereby driving the movable plate 8 to move from right to left. When the rotating rod 15 is rotated counterclockwise, the rotating rod 15 can drive the screw 14 to rotate counterclockwise, thereby driving the movable plate 8 to move from left to right.

[0031] The mounting frame 1 houses a reaction vessel 4, which is embedded within a fixing ring 3. A sealing cover 5 is installed on the top of the reaction vessel 4, and an inlet 6 is fixedly installed on the top of the sealing cover 5. The reaction vessel 4 is widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food industries. It is a pressure vessel used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization and condensation. Its main function is to provide a closed or semi-closed environment for chemical reactions to be carried out under controlled temperature, pressure and stirring conditions.

[0032] The discharge port 10 is funnel-shaped, and the bottom diameter of the discharge port 10 is smaller than the top diameter of the inlet port 6, so that the material can fall accurately into the inlet port 6 when feeding. The top diameter of the storage tank 9 is larger than the diameters of both the discharge port 10 and the inlet port 6.

[0033] Example 2

[0034] like Figure 4As shown, based on the same concept as the above embodiments, this embodiment also proposes: a metering mechanism, which is set inside the movable plate 8. The metering mechanism includes a slot 16, which is opened on the top side of the movable plate 8 and is connected to the interior of the movable plate 8. An insert plate 17 is embedded inside the slot 16 and is slidably connected to the slot 16. A connecting block 18 is fixedly installed on the top side of one side of the insert plate 17. A spring 19 is fixedly installed on the bottom side of the storage tank 9, and the spring 19 is provided in two sets, left and right. The other end of the spring 19 is fixedly connected to the connecting block 18. A rubber pad is pressed onto the outer side of the semi-circular end of the insert plate 17. The rubber pad is made of natural rubber, but is generally synthetic rubber. Synthetic rubber is a rubber material manufactured by chemical synthesis and has properties similar to natural rubber. Synthetic rubber can be formulated according to different needs to obtain specific physical and chemical properties, and has the characteristics of sealing, anti-slip, wear resistance and elasticity. It utilizes the sealing characteristics of rubber to make the interior of the movable plate 8 more sealed, which is beneficial to prevent material leakage.

[0035] One side of the insert plate 17 is set as a semi-cylindrical shape, and the diameter of the semi-cylindrical side is larger than the diameter of the inner wall of the connecting hole, which is conducive to completely sealing the connecting hole inside the movable plate 8.

[0036] Working principle: First, carry the material to be added up the stairs 7, then add the material into the storage tank 9. Hold the rotating rod 15 and start rotating it. The rotation of the rotating rod 15 will drive the screw 14 to rotate. The rotation of the screw 14 will drive the moving plate 8 to move away from the stairs 7. At the same time, the other side of the moving plate 8 will slide outside the sliding rod 13. The sliders 11 on both sides of the moving plate 8 will slide in the sliding groove 12. After moving the moving plate 8 to the top of the inlet 6, stop rotating the rotating rod 15 and hold the connecting block 18 and pull it out. The connecting block 18 will drive the insert plate 17 to move outward, and at the same time stretch the spring 19. The material inside the storage tank 9 will fall into the inlet 6 through the outlet 10 and finally fall into the reactor 4. Then release the connecting block 18. The spring 19 will drive the connecting block 18 and the insert plate 17 to retract due to the elastic force, so that the insert plate 17 returns to its original position. The above is the complete working principle of this utility model.

[0037] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationships.
