Description

Technical Field

[0001] The invention relates to the technical field of chemical material feeding, and in particular to a chemical material safety feeding device. Background Art

[0002] Chemical industry is the abbreviation of chemical process, chemical industry and chemical engineering. Any technology that uses chemical methods to change the composition and structure of substances or synthesize new substances belongs to chemical production technology, that is, chemical process, and the resulting products are called chemicals or chemical products. In chemical production, a variety of feed liquids need to be put into the reactor for chemical reaction to obtain chemical products, so a feeding device is needed to transport the materials into the reaction equipment.

[0003] Authorized patent CN117884043B discloses a chemical safety feeding device, including a top ring, and also includes: a turntable, which is rotatably installed inside the top ring; a barrel, which is vertically arranged below the turntable, and an electric telescopic rod for connecting the barrel is vertically installed on the outer edge of the top of the turntable; an arch breaking assembly, which is arranged inside the barrel, and is used to break the arch of the material inside the barrel; a uniform and complete feeding assembly, which is installed at the bottom of the barrel, the uniform and complete feeding assembly is connected to the inside of the barrel, and is used to feed the material inside the barrel in steps.

[0004] When the chemical safety feeding device in the above patent is in use, the material in the barrel is received through the discharge barrel and fed into the reactor, and the discharge barrel adopts a similar impeller mechanism to separate the material for rotation and output. As the impeller mechanism rotates, the gap between it and the bottom of the discharge barrel becomes larger and larger, so the feeding outlet gradually increases. The feeding amount in a single feeding shows a gradual increase trend, the material feeding is uneven, and the reaction rate is not easy to control, which affects the chemical production quality and process stability. In addition, the feeding amount for the local area in the second half of the single feeding is relatively large, and the feeding coverage is small. For some chemical reactions with violent reactions, it is easy to cause side reactions and involve safety issues. When the feeding is relatively concentrated, it is also easy to reduce the reaction rate. When a similar impeller mechanism is used to feed materials, the single feeding amount is fixed, and it is difficult to adjust the single feeding amount according to the required control in different reaction stages. Summary of the invention

DETAILED DESCRIPTION

[0034] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Embodiment 1

[0035] like Figure 1-Figure 10 As shown, a chemical safety feeding device comprises a reactor 1, a bracket 11 is fixedly installed on the periphery of the reactor 1, a sealing cover 12 is fixedly connected to the top of the reactor 1, a barrel 13 is fixedly inserted on the top of the sealing cover 12, a hopper 2 is rotatably connected to the bottom of the sealing cover 12, a rectangular feed opening is formed by contraction at the bottom of the hopper 2, a rotating disk 21 rotatably connected to the inner wall of the reactor 1 is fixedly sleeved on the periphery of the bottom of the hopper 2, a partition bin 24 is arranged in the middle of the rectangular feed opening, the partition bin 24 divides the rectangular feed opening into two front and rear feed troughs, a wavy material dividing strip 25 is fixedly connected to the lower wall of the feed trough, and a plurality of material dispersing rods 51 are arranged in the two feed troughs;

[0036] A moving frame 3 is slidably connected to the bottom of the partition bin 24, and a pressing strip 31 is slidably connected to the front and rear sides of the moving frame 3. A plurality of linearly distributed pressing wheels 32 are rotatably connected to the outer side of the pressing strip 31. The pressing wheels 32 and the pressing strip 31 can respectively seal and dock with the material separation strip 25. An abutment spring 33 is fixedly connected between the two pressing strips 31. An elastic plate 34 is slidably connected to the partition bin 24. A hinge rod 35 is movably connected between the elastic plate 34 and the moving frame 3. A step block 36 is slidably connected to the elastic plate 34. A connecting frame 5 is fixedly connected between the elastic plate 34 and the material separation rod 51.

[0037] A driving cone rod 4 is rotatably connected to the middle part of the partition chamber 24, and the driving cone rod 4 is driven by a motor 1 installed on the right wall of the partition chamber 24. A cam 1 41 is fixedly sleeved on the driving cone rod 4, and cams 2 42 are arranged on both sides of the cam 1 41. The inner cavity of the sealing cover 12 is provided with multiple groups of circumferentially distributed tooth rollers 61, and a plurality of stirring blades 62 are arranged on the tooth rollers 61.

[0038] When in use, the step block 36 is controlled to move to the right, and the driving cone rod 4 is controlled to rotate and the hopper 2 is rotated. The driving cone rod 4 cannot drive the cam 41 to intermittently squeeze the step block 36 so that each feeding outlet is intermittently opened, and then the material can be added. The material is added to the hopper 2 through the barrel 13, and the material falls and accumulates on the edge of the inner cavity of the rotating hopper 2, and part of it automatically slides into the front and rear feeding troughs. When the hopper 2 rotates, the material driven by it is passively squeezed and flowed by each tooth roller 61. Therefore, under the action of the tooth roller 61, automatic material spreading can be achieved, and the front and rear feeding troughs can be automatically filled with materials, thereby ensuring The spring 33 is pressed against the pressing bar 31 and the pressing bar 32 is pressed against the pressing bar 31. The pressing bar 31 is pressed against the pressing bar 31 and the pressing bar 32 is pressed against the pressing bar 31. The pressing bar 31 is pressed against the pressing bar 31 and the pressing bar 32 is pressed against the pressing bar 31. The pressing bar 31 is pressed against the pressing bar 31 and the pressing bar 32 is pressed against the pressing bar 31. The pressing bar 31 is pressed against the pressing bar 31 and the pressing bar 32 is pressed against the pressing bar 31. The plate 34 automatically moves up and resets under the action of its own elastic force, and the compression abutment spring 33 automatically extends to drive the pressing strip 31 to reset the pressing wheel 32 and engage with the dividing strip 25 to close the feeding outlet. Subsequently, when the driving cone rod 4 drives the cam 41 to squeeze the step block 36 again, each feeding outlet is opened again, and the feeding is carried out intermittently. Since the feeding outlet is affected by the front and rear two feeding troughs to form two rows in front and back, and the feeding is carried out in a rotating manner, the feeding is relatively dispersed and extensive, thereby improving the reaction rate. Moreover, since the local feeding amount is small during feeding, the feeding amount is controlled, avoiding side reactions caused by a large feeding amount. The feeding is safe. During the feeding, the pressing strip 31 drives the pressing wheel 32 to reset intermittently and dock with the dividing strip 25, which can squeeze and break the material stuck in the feeding outlet to avoid blockage. At the same time, when the elastic plate 34 moves up and down, it drives the connecting frame 5 and the discharging rod 51 to squeeze and guide the material at the top entrance of the feeding trough and inside thereof, respectively, which also ensures smooth feeding, no accidental interruption of feeding, and safe and reliable feeding. In addition, when feeding, the two cams 42 are controlled to deflect in opposite directions, which can change the single extrusion time, so that the single feeding amount of the feeding outlet can be controlled according to different feeding needs, thereby improving feeding safety. Embodiment 2

[0039] On the basis of the above embodiment, a driving mechanism of the hopper 2 is provided:

[0040] like Figure 2 and Figure 5As shown, a rotating gear 22 is rotatably connected to the upper right surface of the rotating disk 21, and a bevel gear 23 meshing with the driving cone rod 4 is fixedly connected to the upper end of the rotating gear 22. An annular tooth groove 1 meshing with the rotating gear 22 is provided on the inner wall of the reactor 1.

[0041] When the control motor drives the driving cone rod 4 to rotate, the driving cone rod 4 engages and drives the bevel gear 23 to rotate, and the rotating gear 22 is thereby driven to continuously engage with the annular tooth groove, so that the hopper 2 rotates, thereby continuously adjusting the feeding area when feeding materials. At the same time, the rotating hopper 2 can cooperate with the tooth roller 61 and the stirring blade 62 to continuously lay the material into the feeding troughs on the front and rear sides during the feeding process, thereby ensuring continuous feeding. Embodiment 3

[0042] Based on the above embodiments:

[0043] like Figure 8 As shown, the top of the partition bin 24 is in an inverted V shape, the connecting frame 5 is composed of two L-shaped connecting rods and a pressure rod that movably pass through the top of the partition bin 24, and the material discharge rod 51 is fixedly connected to the bottom of the pressure rod.

[0044] When the material in the hopper 2 is continuously laid into the two feeding troughs in the rectangular material opening, the inverted V-shape on the top of the partition bin 24 can prevent the material from being blocked and accumulated here, affecting the overall fluidity of the material. At the same time, it can also prevent the material from remaining here when the material is subsequently emptied. Embodiment 4

[0045] Based on the above embodiments:

[0046] like Figure 7 As shown, a slope is provided on one side of the upper end of the dividing strip 25 facing the pressing strip 31 .

[0047] The inclined surface is provided to facilitate rapid discharge and delivery of materials, thereby avoiding affecting the smoothness of material delivery. Accordingly, when delivering materials, the pressing strip 31 can drive the pressing wheel 32 to retract and move toward the inside of the moving frame 3, and the materials on the upper surfaces of the pressing strip 31 and the pressing wheel 32 can be scraped off by the moving frame 3, so that each feeding outlet can deliver materials smoothly. Embodiment 5

[0048] On the basis of the above embodiment, an adjustment mechanism of the cam 2 42 is provided:

[0049] like Figure 8-Figure 9 As shown, the two cams 42 are both rotatably connected to the driving cone rod 4, and the inner walls of the two cams 42 are provided with guide grooves 43, the guide grooves 43 are composed of a left arc groove and a right straight groove connected and combined, and the arc grooves in the two guide grooves 43 are in opposite directions;

[0050] A slide groove is provided in the middle of the driving cone rod 4, and a guide rod 44 is slidably inserted in the slide groove. Pin protrusions 45 movably engaged with the guide groove 43 are respectively provided on the left and right sides of the lower wall of the guide rod 44. A slip ring 46 movably sleeved on the outer periphery of the driving cone rod 4 is fixedly connected to the left end of the guide rod 44. A shaft sleeve 47 slidably connected to the inner wall of the partition chamber 24 is rotatably sleeved on the outer periphery of the slip ring 46. An adjusting screw 49 threadably inserted into the shaft sleeve 47 is rotatably connected to the middle of the partition chamber 24. The adjusting screw 49 is driven by a motor 2 arranged in the middle of the partition chamber 24.

[0051] The initial pin convex 45 is movably engaged with the connection between the arc groove and the straight groove in the guide groove 43, and the control motor 2 drives the adjusting screw 49 to rotate so that the sleeve 47 moves to the left, and the sleeve 47 thereby pulls the slip ring 46 to move the guide rod 44 to the left, and the two pin convex 45 squeeze the arc grooves in the corresponding guide grooves 43 to drive the two cams 42 to deflect in opposite directions, thereby relatively increasing the extrusion arc length of the outer end of the original cam 1 41, and the single extrusion time of the step block 36 is increased immediately, and the single material delivery amount is increased, and the control motor 2 drives the adjusting screw 49 to rotate so that the sleeve 47 moves to the right, which can correspondingly control the single material delivery amount to be reduced, and the material delivery amount control is reliable. Embodiment 6

[0052] On the basis of the above embodiment, an adjustment mechanism of the step block 36 is provided:

[0053] like Fig. 9 As shown, a lever 48 is fixedly connected to the bottom of the shaft sleeve 47, and the lever 48 is slidably inserted on the lower step horizontal surface of the step block 36, and a slope is provided between the upper and lower step horizontal surfaces of the step block 36.

[0054] When the control sleeve 47 moves to the left so that the two cams 42 are deflected in opposite directions respectively, so as to relatively increase the extrusion arc length of the outer end of the original cam 1 41, the sleeve 47 synchronously drives the lever 48 to move the step block 36 to the left, and the upper step horizontal surface of the step block 36 maintains a sufficient contact portion with the cam 1 41 and the cam 2 42. When the cone rod 4 is driven to rotate, it can still drive the cam 1 41 and the cam 2 42 to extrude the step block 36, without affecting the controlled release of the material;

[0055] When the control sleeve 47 moves to the right by the maximum distance, the sleeve 47 pushes the slip ring 46 so that the guide rod 44 drives the pin 45 to move to the right by the maximum distance along the straight groove in the guide groove 43, and the two cams 42 still maintain the initial stable state of coinciding with the cam 1 41, and the step block 36 is driven by the lever 48 so that the lower step horizontal surface on it moves to below the cam 1 41 and the cam 2 42, so that the step block 36 cannot be squeezed, and each feeding port is automatically in a closed state, which is convenient for controlling the stopping of material feeding at any time, and is safe and reliable to use. At the same time, it is also convenient to close each feeding port when laying materials in the initial hopper 2 to avoid uneven feeding.

[0056] By providing a slope between the upper and lower stepped horizontal surfaces of the step block 36, it is possible to ensure that the step block 36 moves smoothly and stably relative to the rotating cam 1 41 and the cam 2 42 during transmission switching. Embodiment 7

[0057] Based on the above embodiment, a driving mechanism of the toothed roller 61 is provided:

[0058] like Figure 2 As shown, a positioning column 6 is fixedly connected to the middle of the inner cavity of the sealing cover 12, and the positioning column 6 is rotatably connected to the top of the partition chamber 24. The gear roller 61 is rotatably connected between the positioning column 6 and the sealing cover 12. The number of each group of gear rollers 61 is two, and each group of gear rollers 61 is meshed and connected with each other;

[0059] The upper end of the hopper 2 is provided with two annular tooth grooves, and the lower tooth roller 61 is meshed and connected with the two annular tooth grooves.

[0060] Furthermore, the stirring blades 62 are distributed along the circumference of the outer periphery of the toothed roller 61 , and are distributed linearly along the axial direction of the outer periphery of the toothed roller 61 , and the stirring blades 62 between each group of toothed rollers 61 are staggered.

[0061] When the hopper 2 rotates to feed the material, the hopper 2 drives the annular tooth groove 2 at the upper end to continuously mesh with the tooth roller 61 at the lower side, and the two tooth rollers 61 in each group mesh with each other and rotate, and the stirring blades 62 between the two meshing tooth rollers 61 are staggered. Each group of tooth rollers 61 can not only spread the material flat, but also break the arch of the material to avoid caking and other obstacles to the flow of the material.

[0062] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
