Description

Technical Field

[0001] This utility model relates to a technology for producing sizing agents, specifically an AKD neutral sizing agent production device. Background Technology

[0002] AKD surface sizing agent is a chemical additive commonly used in the papermaking industry. Its main component is alkyl ketene dimer (AKD).

[0003] Chinese patent discloses a continuous production apparatus for AKD surface sizing agent (authorization announcement number CN221452329 U). This patented technology, by activating a brake motor, causes a rotating shaft to drive a half-gear, which in turn causes a toothed plate to move a sliding plate and a baffle backward, stretching a spring. This releases the baffle from obstructing the additive in the hopper. As the half-gear rotates and the spring returns to its original position, the baffle returns to its original position, thus achieving intermittent additive feeding. This makes subsequent mixing easier and more uniform, improving the production quality of the sizing agent. However, this patented technology suffers from intermittent feeding with a rapid return characteristic, unstable additive feeding rate, and the need for an additional motor to control the intermittent feeding. Therefore, those skilled in the art have provided an AKD neutral sizing agent production apparatus to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an AKD neutral sizing agent production apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

The kettle lid is installed on the top of the kettle body, and the iris unloading device 1 and the iris unloading device 2 with the same structure are installed on the kettle lid.

[0007] As a further embodiment of this utility model: an intermittent reversing device 1 and an intermittent reversing device 2 with the same structure are installed on the lid of the vessel. An iris unloading device 1 is installed on the side of the intermittent reversing device 1, and an iris unloading device 2 is installed on the side of the intermittent reversing device 2. A feeding hopper 1 is installed at the upper end of the iris unloading device 1, and a feeding hopper 2 is installed at the upper end of the iris unloading device 2. The feeding hopper 1 and the feeding hopper 2 have the same structure.

[0008] As a further embodiment of this utility model: the bevel gear set includes a top bevel gear, a bottom bevel gear, a first side bevel gear, and a second side bevel gear. The first side bevel gear and the second side bevel gear are symmetrically arranged on both sides of the upper end of the bottom bevel gear. The top bevel gear is installed on the upper end of the first side bevel gear and the motor is installed on the upper end of the top bevel gear. The half gear shaft of the first intermittent reversing device is installed on the outer side of the first side bevel gear, and the second intermittent reversing device is installed on the outer side of the second side bevel gear.

[0009] As a further embodiment of this utility model: the intermittent reversing device includes a first half gear, a second half gear, a gear shaft, a bearing bracket, and a dial. The dial is mounted on the lid of the vessel and on the outside of the first gear. The outside of the dial has several teeth and meshes with the first gear. Several cylinders are arranged in a circumferential array on the dial, and the first half gear and the second half gear are arranged on the upper end of the cylinders. The first half gear and the second half gear are mounted on both sides of the dial. The first half gear and the second half gear are mounted on the half gear shaft. Several teeth are arranged on the first half gear and the second half gear. The half gear shaft is mounted on the bearing bracket, and the bearing bracket is mounted on the lid of the vessel.

[0010] As a further embodiment of this utility model: the iris unloading device includes a baffle, a rotating seat, and a fixed seat. The rotating seat is provided with six inclined slots, and a sliding column is installed in each inclined slot of the rotating seat. The sliding column is located on the top of the baffle. A total of six baffles are installed below the rotating seat. A slider is provided at the bottom of the baffle. The slider is installed in a hexagonal slot. The hexagonal slot is located in the fixed seat and the hexagonal slot is regular hexagonal. The baffle is installed between the rotating seat and the fixed seat. The fixed seat is installed on the lid of the vessel. A gear is installed at the top of the rotating seat. The rotating seat and the gear are fixedly connected.

[0011] As a further embodiment of this utility model: a stirring rod is installed at the center of the vessel lid, and two spiral blades are installed on the stirring rod. The stirring rod and spiral blades are arranged in the vessel body. The bottom bevel gear of the bevel gear set is installed at the top of the stirring rod. A motor mounting bracket is installed at the center of the upper end of the vessel lid. A motor is installed at the top of the motor mounting bracket. The motor mounting bracket is located outside the bottom bevel gear. A feed inlet is provided on the vessel lid. A tripod is provided at the bottom of the vessel body. A discharge outlet is provided at the center of the bottom of the vessel body.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The iris unloading device 1 used in this utility model can evenly open and close the additives in the first and second feeding hoppers. The opening of the iris unloading device 1 is achieved by the sliding block sliding in the hexagonal groove and the sliding column sliding in the inclined groove. When the iris unloading device 1 is opened, the rotating seat and the fixed seat rotate relative to each other. The gear 1 is driven by the dial to rotate, thereby rotating the rotating seat. As a result, the baffle slides outward along the hexagonal groove and the inclined groove. The center of the iris unloading device 1 opens evenly. The iris unloading device 1 has a more reasonable feeding rate than the simpler single-piece baffle opening and closing device. The principle of the iris unloading device 2 is the same as that of the iris unloading device 1.

[0014] 2. The intermittent reversing device I used in this utility model can intermittently reverse, thereby making the iris unloading device I open and unload regularly and smoothly. Since half gear I and half gear II are provided with several teeth in an uneven manner, half gear I or half gear II can only drive the dial to rotate for part of the entire rotation cycle. When half gear I moves the dial, the teeth on half gear II just rotate into the air. At this time, half gear II does not drive the dial. When half gear II moves the dial, since half gear II and half gear I are just set on both sides of the dial, half gear I drives the dial to reverse. Thus, the intermittent reversing device I reverses periodically, making the iris unloading device I open and close periodically. By changing half gear I and half gear II with different numbers of teeth, the ratio of forward and reverse rotation time can be controlled, thereby controlling the proportion of unloading time to the overall working time of this utility model. The intermittent reversing device II has the same principle and structure as the intermittent reversing device I. The intermittent reversing device II reverses periodically, making the iris unloading device II open and close periodically.

[0015] 3. The bevel gear set used in this utility model enables a single motor to drive the entire production device, avoiding the increased costs and motor linkage control problems caused by additional motor installation. The power of the top bevel gear is transmitted to the second side bevel gear and the first side bevel gear, which in turn drive the bottom bevel gear. Thus, when the screw blade and stirring rod rotate, the first iris unloading device and the first intermittent reversing device also work simultaneously. When the screw blade and stirring rod stop, the first iris unloading device and the first intermittent reversing device also stop working simultaneously, avoiding additional start-up and shutdown operations.

[0029] The working principle of this utility model:

[0030] The iris unloading device 2 used in this utility model can evenly open and close the additives in the feeding hopper 3 and the second feeding hopper 301. The opening of the iris unloading device 2 is achieved by the sliding block 206 sliding in the hexagonal groove 205 and the sliding column 207 sliding in the inclined groove 204. When the iris unloading device 2 is opened, the rotating seat 202 and the fixed seat 203 rotate relative to each other. The dial 607 drives the gear 208 to rotate, thereby rotating the rotating seat 202. As a result, the baffle 201 slides outward along the hexagonal groove 205 and the inclined groove 204. The center of the iris unloading device 2 opens evenly. The iris unloading device 2 has a more reasonable feeding rate than the simpler single-piece baffle opening and closing device. The principle of the iris unloading device 209 is the same as that of the iris unloading device 2.

[0031] The intermittent reversing device 6 used in this invention can intermittently reverse, thereby causing the iris unloading device 2 to open and discharge material regularly. Since both half-gear 602 and half-gear 603 have several teeth 608 unevenly arranged, half-gear 602 or half-gear 603 can only drive the dial 607 to rotate for a portion of the entire rotation cycle. When half-gear 602 moves the dial 607, the teeth 608 on half-gear 603 are just in the air, and at this time, half-gear 603 does not transmit power to the dial 607. However, when half-gear 603 moves the dial 607, the teeth 608 on half-gear 603 are in the air. 603 and half gear 602 are positioned on both sides of dial 607. Therefore, half gear 602 drives dial 607 to reverse, thereby causing intermittent reversing device 6 to periodically reverse, which causes iris unloading device 2 to periodically open and close. By changing half gear 602 and half gear 603 with different numbers of teeth, the ratio of forward and reverse rotation time can be controlled, thereby controlling the proportion of unloading time to the overall working time of this utility model. Intermittent reversing device 2 601 has the same principle and structure as intermittent reversing device 6. Intermittent reversing device 2 601 periodically reverses, causing iris unloading device 2 209 to periodically open and close.

[0032] The bevel gear set 7 used in this utility model enables a single motor 5 to drive the entire production device, avoiding the increased cost and motor linkage control problems caused by additional motor installation. The power of the top bevel gear 701 is transmitted to the side bevel gear 704 and the side bevel gear 703, and then to the bottom bevel gear 702. Thus, when the screw blade 8 and the stirring rod 9 rotate, the iris unloading device 2 and the intermittent reversing device 6 also work simultaneously. When the screw blade 8 and the stirring rod 9 stop, the iris unloading device 2 and the intermittent reversing device 6 also stop working simultaneously, avoiding additional start-up and shutdown operations.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
