Description

Technical Field

[0001] This utility model relates to the field of chemical feeding technology, and in particular to a chemical safety feeder. Background Technology

[0002] Chemical industry is an abbreviation for chemical processes, chemical industry, and chemical engineering. In chemical production, various chemical raw materials are put into a reaction vessel to carry out chemical reactions according to production needs, thereby obtaining chemical products. Among them, chemical raw materials include liquid chemical raw materials, solid chemical raw materials, and powdered chemical raw materials. When chemical raw materials are put into the reaction vessel during the chemical production process, a feeder is required.

[0003] According to the Chinese patent "A Chemical Safety Feeder" authorized announcement number "CN221359772U", the material storage box can be easily put into the storage box by pulling the handle to open the sealing cover, and the material is discharged through the rotating guide plate. It is easy to operate and use, and does not require manual feeding multiple times, which can reduce the labor intensity and health hazards to workers.

[0004] Although the above application allows chemical raw materials to be placed in storage bins for feeding, when feeding powdered chemical raw materials, the staff will come into close contact with the powdered raw materials being poured into the storage bins, and some of the powdered raw materials will scatter during the pouring process, which will still affect the health of the staff. Utility Model Content

[0005] Therefore, it is necessary to provide a chemical safety feeder to address the issue that workers will come into close contact with the powdered chemical raw materials during the process of putting them into the storage bin, and that some of the powdered raw materials will scatter during the pouring process, which may still affect the health of the workers.

[0006] Includes: a fixed frame, on the inner side of which a feeding box is installed, and the discharge pipe at the bottom of the feeding box is connected to the feed pipe of the reactor; The feeding mechanism includes a placement plate rotatably connected to the upper end of the inner wall of the feeding box. A first motor is fixedly connected to one side of the feeding box, and the output shaft of the first motor is fixedly connected to the rotation shaft of the placement plate. A movable plate is slidably connected to one side of the inner wall of the placement plate. A plurality of evenly distributed conical rods are fixedly connected to the top of the movable plate. A movable rod is slidably connected to one side of the inner wall of the feeding box. A mounting plate is fixedly connected to one end of the movable rod. A plurality of blades are fixedly connected to one side of the mounting plate. A sieve plate is slidably connected to the lower end of the inner wall of the feeding box.

[0007] In one embodiment, the feeding mechanism further includes a second motor mounted on the surface of the feeding box. The output shaft of the second motor extends through the feeding box and is fixedly connected to a cam. The surface of the cam contacts the bottom end of the screen plate. A push rod is fixedly connected to one side of the top of the screen plate, and a round rod is fixedly connected to one side of the moving plate. The interaction between the push rod and the round rod facilitates the simultaneous up-and-down reciprocating movement of the moving plate during the feeding process, driving the screen plate to vibrate and feed material. Multiple conical rods also drive the raw material packaging bag to continuously reciprocate up and down, shaking the bag and ensuring sufficient material is fed out of the packaging bag.

[0008] In one embodiment, the bottom of the feeding box is inclined, and the screen plate is also inclined. This facilitates better material feeding.

[0009] In one embodiment, the vertical cross-section of the push rod is circular, and the diameter of the push rod is larger than the diameter of the circular rod. This helps to ensure the push rod effectively pushes the circular rod.

[0010] In one embodiment, a limiting block is fixedly connected to one side of the inner wall of the feeding box, and the center point of the limiting block is located on the same horizontal plane as the center point of the mounting plate. This helps to limit the movement distance of the mounting plate, thereby preventing the mounting plate from causing the blade to move excessively.

[0011] In one embodiment, a groove is formed on one side of the inner wall of the placement plate, and the surface of the movable plate is slidably connected to the inner wall of the groove. This facilitates limiting the movement path of the movable plate, and also limits the minimum downward movement height of the movable plate when it rotates to a vertical position, ensuring contact between the round rod and the push rod.

[0012] In one embodiment, the movable rod is a rectangular rod, with one end of the rod away from the mounting plate extending through the feeding box and fixedly connected to a round block. The rectangular movable rod prevents rotation during the movement of the mounting plate and blades, while the round block facilitates easier pulling of the rod by the operator.

[0013] In one embodiment, limiting plates are fixedly connected to both sides of the inner wall of the fixing frame, and the surface of the limiting plates is slidably connected to the inner wall of the sieve plate. This facilitates the limiting of the sieve plate and ensures the stability of the sieve plate during movement. Beneficial effects

[0014] 1. In the above-mentioned feeding mechanism, bagged powdered chemical raw materials are placed inside the feeding box and supported by a placement plate. After the opening of the feeding box is sealed, multiple blades are pulled to break one side of the packaging bag. After breaking the bag, the packaging bag is gradually tilted, which facilitates the automatic pouring out of the powder inside the packaging bag for feeding. The material is discharged through the vibration of the screen plate to avoid material blockage. At the same time, under the interaction of the push rod and the round rod, the vibration of the screen plate helps to drive the moving plate to move the raw material packaging bag up and down repeatedly through multiple conical rods, shaking the packaging bag and ensuring that the powder raw materials inside the packaging are fully discharged. This solution avoids workers directly pouring out the raw materials during feeding, thereby avoiding direct contact between workers and chemical powder raw materials and strengthening the protection of workers during the feeding process. 2. The rectangular moving rod prevents rotation during the movement of the mounting plate and blade, ensuring the blade can properly tear the packaging bag. The limiting block helps to limit the movement distance of the mounting plate, thus preventing the mounting plate from moving the blade excessively. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0019] The following is combined Figures 1-5 This invention describes a chemical safety feeder.

[0020] In one embodiment, a chemical safety feeder includes: a fixed frame 100, a feed box 200 installed on the inner side of the fixed frame 100, and a discharge pipe at the bottom of the feed box 200 connected to the feed pipe of the reactor. The feeding mechanism 300 includes a placement plate 310 rotatably connected to the upper end of the inner wall of the feeding box 200. A first motor 320 is fixedly connected to one side of the feeding box 200. The output shaft of the first motor 320 is fixedly connected to the rotation shaft of the placement plate 310. A movable plate 311 is slidably connected to one side of the inner wall of the placement plate 310. A plurality of evenly distributed cone rods 312 are fixedly connected to the top of the movable plate 311. A movable rod 330 is slidably connected to one side of the inner wall of the feeding box 200. A mounting plate 331 is fixedly connected to one end of the movable rod 330. A plurality of blades 332 are fixedly connected to one side of the mounting plate 331. A sieve plate 340 is slidably connected to the lower end of the inner wall of the feeding box 200.

[0021] In this embodiment, the discharge pipe at the bottom of the feeding box 200 and the feed pipe of the reactor can be fixedly installed through a flange. The rotation axis of the placement plate 310 is located on the off-axis of the feeding box 200. In the initial state, the placement plate 310 is in a horizontal state. There is a certain distance between the side of the placement plate 310 near the blade 332 and the blade 332 to avoid mutual interference between the placement plate 310 and the blade 332 during rotation. The horizontal height of the bottom blade 332 is higher than the horizontal height of the top of the placement plate 310.

[0022] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the feeding mechanism 300 also includes a second motor 350 mounted on the surface of the feeding box 200. The output shaft of the second motor 350 passes through the feeding box 200 and is fixedly connected to a cam 351. The surface of the cam 351 contacts the bottom end of the screen plate 340. A push rod 341 is fixedly connected to one side of the top end of the screen plate 340, and a round rod 313 is fixedly connected to one side of the moving plate 311.

[0023] In this embodiment, in the initial state, the lowest point of the cam 351 contacts the bottom end of the sieve plate 340. At this time, the sieve plate 340 is at its lowest height. When the placement plate 310 is in a horizontal state, the round rod 313 is located on one side of the moving plate 311. The controller starts the first motor 320, causing its output shaft to rotate the placement plate 310 counterclockwise by 90 degrees. During this rotation, the moving plate 311 moves downwards under its own weight. When the placement plate 310 is in a vertical position after rotation, the moving plate 311 moves downwards to its lowest point, at which point the lower end of the round rod 313 is in contact with the upper end of the push rod 341. Then, the controller starts the second motor 350, whose output shaft drives the cam 351. During the process of rotating from the lowest point to the highest point and contacting the bottom of the sieve plate 340, the cam 351 will push the sieve plate 340 to move upward, and under the action of the push rod 341 and the round rod 313, it will push the moving plate 311 to move upward synchronously. When the output shaft of the second motor 350 drives the cam 351 to rotate from the highest point to the lowest point and contact the bottom of the sieve plate 340, the sieve plate 340 and the moving plate 311 will lose the compression and move downward under their own weight, so that the bottom of the sieve plate 340 is always in contact with the surface of the cam 351, and the round rod 313 is always in contact with the push rod 341.

[0024] like Figure 1 and Figure 5 As shown, the bottom of the feeding box 200 is inclined, and the screen plate 340 is also inclined.

[0025] In this embodiment, the discharge pipe at the bottom of the feeding box 200 is located at the lowest point of the bottom of the feeding box 200, so that the powder passing through the sieve plate 340 can fully enter the discharge pipe for feeding.

[0026] like Figure 5 As shown, the vertical cross-section of push rod 341 is circular, and the diameter of push rod 341 is larger than the diameter of circular rod 313.

[0027] In this embodiment, when the placement plate 310 is rotated to a vertical state, the center of the round rod 313 and the center of the push rod 341 are on the same axis.

[0028] like Figure 2 As shown, a limiting block 210 is fixedly connected to one side of the inner wall of the feeding box 200, and the center point of the limiting block 210 and the center point of the mounting plate 331 are located on the same horizontal plane.

[0029] In this embodiment, when the bagged powdered chemical raw material is placed on the placement plate 310 in the initial state, the blade 332 is at a certain distance from both ends of the packaging. When the moving rod 330 is pulled, the movement distance of the blade 332 towards the edge is limited by the action of the limiting block 210, so as to prevent the blade 332 from moving to the end of the packaging bag, thereby preventing the side of the packaging bag from completely falling off after the blade 332 breaks the side of the packaging bag.

[0030] like Figure 5 As shown, a groove 314 is provided on one side of the inner wall of the placement plate 310, and the surface of the movable plate 311 is slidably connected to the inner wall of the groove 314.

[0031] In this embodiment, when the placement plate 310 is rotated to a vertical state, the moving plate 311 moves downward to its lowest height within the slide groove 314, at which point the round rod 313 contacts the push rod 341.

[0032] like Figure 2 As shown, the movable rod 330 is a rectangular rod, and the end of the movable rod 330 away from the mounting plate 331 passes through the feeding box 200 and is fixedly connected to a round block 334.

[0033] In this embodiment, in the initial state, one end of the circular block 334 is in contact with one side of the feeding box 200, and the inner wall of the circular block 334 is threaded with a bolt. One side of the feeding box 200 is provided with a threaded hole that matches the bolt. The operator can use the bolt and the threaded hole to thread-connect the circular block 334 for fixing.

[0034] like Figure 3 As shown, limiting plates 220 are fixedly connected to both sides of the inner wall of the fixing frame 100, and the surface of the limiting plates 220 is slidably connected to the inner wall of the sieve plate 340. The limiting plates 220 limit the sieve plate 340.

[0035] Working principle: When feeding bagged powdered chemical raw materials, the top cover of the feeding box 200 is opened, the bagged powder raw material is placed on the placement plate 310, and the side of the packaging bag is brought into contact with the blades 332. At the same time, multiple conical rods 312 are inserted into the packaging bag. After placement, the top cover of the feeding box 200 is closed. At this time, the operator pulls the moving rod 330, which drives the multiple blades 332 to move through the mounting plate 331. During the movement, the blades 332 will tear the side of the packaging bag. When the moving rod 330 can no longer move, the bag tearing process is completed, and the moving rod 330 is pushed back to its original position. At this time, the controller starts the first motor 320, which drives the placement plate 310 to rotate slowly counterclockwise by 90 degrees. During the rotation... The placement plate 310 gradually tilts, and the packaging bag tilts synchronously under the action of the cone rod 312. During this process, the powder in the packaging bag will automatically leak out through the broken opening and fall onto the sieve plate 340. When the placement plate 310 rotates ninety degrees, the first motor 320 is turned off. At this time, the lower end of the surface of the round rod 313 contacts the upper end of the surface of the push rod 341, and the second motor 350 is started by the controller. Under the action of the cam 351 and the weight of the sieve plate 340, the sieve plate 340 will be driven to vibrate up and down. The push rod 341 and the round rod 313 drive the moving plate 311 to drive the packaging bag to shake up and down through multiple cone rods 312. During this process, the powder is reacted in the reactor through the discharge pipe at the bottom of the sieve plate 340 and the feed pipe of the reactor.

[0036] It should be noted that the motors and other components mentioned above are all devices with relatively mature existing technologies. The specific model can be selected according to actual needs. The motor can be powered by a built-in power supply or by AC power. The specific power supply method should be selected according to the situation, and will not be elaborated here.

[0037] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
