Description

Technical Field

[0001] This utility model relates to the field of molecular sieve particle technology, specifically to a molecular sieve particle forming device. Background Technology

[0002] Molecular sieves, as porous materials with regular pore structures, have wide applications in many chemical fields such as adsorption separation, catalytic reactions, and gas drying. To meet the needs of different applications, molecular sieves are often processed into particles of specific shapes and sizes. Particle forming is one of the key production steps. When producing particles of different diameters, the machine must be stopped and the forming mold (template or perforated plate) at the bottom of the extrusion cylinder must be replaced. This process is cumbersome and time-consuming, seriously affecting production efficiency, especially inconvenient for small-batch, multi-specification production. Utility Model Content

[0003] In view of the problems existing in the prior art, this utility model discloses a molecular sieve particle forming device. The technical solution adopted includes a base frame, support columns, I-shaped plate, integrated fixing ring, extrusion cylinder, screw feeder drive motor, screw feeder, feed pipe, feed inlet, speed adjustable motor, controller, left rotating shaft, cutting blade, right stepper motor, connecting shaft, mounting plate, barrier column, forming channel, and bottom guide. The I-shaped plate is connected to the base frame through the support columns. The I-shaped plate has an integrated fixing ring in the middle, which is fixed to the outer wall of the extrusion cylinder. The fixing method can be welding. A screw feeder is installed at the top of the extrusion cylinder. The actuator drives the internal spiral feeder, which is powered by an external power source. A feed inlet is located on the upper left side of the extrusion cylinder, connected to a feed pipe. A speed-adjustable motor and controller are mounted on the upper left side of the I-beam plate, while a right-side stepper motor is mounted on the upper right side. The speed-adjustable motor on the left is powered by a battery within the controller, which adjusts its speed. The output shaft of the speed-adjustable motor extends from a through-hole on the I-beam plate downwards, where a cutting blade is fixedly mounted. The cutting frequency of the cutting blade changes with the speed adjustment, thus controlling the cutting of the material strip. The cutting length is adjusted by extending the output shaft of the right-side stepper motor from the through hole on the I-beam plate downwards and fixing a mounting plate at the lower end. Four barrier posts are distributed circumferentially on the side of the mounting plate, each with a forming channel. These barrier posts, located at the opening below the extrusion cylinder, completely seal the opening. To improve the tightness of the seal, the entire barrier post can be made of hard rubber, with its upper surface one millimeter above the bottom of the extrusion cylinder. When it rotates to the bottom of the extrusion cylinder, its upper surface is compressed, causing the rubber to deform and allowing the barrier post to fit tightly against the bottom of the extrusion cylinder, preventing leakage. The diameter of the forming channel on different barrier posts varies. Similarly, by rotating different barrier columns to the bottom of the extrusion cylinder, the diameter of the particles can be adjusted accordingly to ensure that the diameter of the extruded product meets the requirements. A bottom guide is set on the base frame, and the extruded and cut particles are recycled under the guidance of the bottom guide. The mounting plate is integrally formed of high-strength alloy steel, and its thickness is not less than 1 / 3 of the height of the barrier column. The root of the barrier column is embedded into the mounting plate through a flange structure and fastened with bidirectional through bolts at the connection. The metal skeleton inside the barrier column extends into the mounting plate and is double-fixed with the mounting plate through interference fit and welding to ensure that the extrusion pressure is transmitted axially to the entire mounting plate.

[0004] As a preferred technical solution of this utility model, a flared opening is provided at the upper end of the feed pipe to reduce the risk of material falling during feeding.

[0005] As a preferred technical solution of this utility model, the speed-adjustable motor is a DC brushed motor, which is controlled by a controller.

[0006] As a preferred technical solution of this utility model, the cutting blade is made of stainless steel.

[0007] As a preferred technical solution of this utility model, the bottom guide part includes a bottom mounting groove and a trapezoidal guide frame. The bottom mounting groove is opened in the middle of the base frame, in which the trapezoidal guide frame can be detachably installed. The surface of the inclined part of the trapezoidal guide frame is covered with a smooth material layer. The bottom of the trapezoidal guide frame is made of iron. A magnet is fixed at the bottom of the bottom mounting groove, and the trapezoidal guide frame is spliced ​​and installed by magnetic attraction.

[0008] The beneficial effects of this invention are as follows: By distributing multiple barrier posts with forming channels of different diameters around the circumference of the mounting plate, and using a stepper motor on the right side to drive the mounting plate to rotate, the forming channel of the required diameter can be quickly and accurately rotated and positioned at the opening below the extrusion cylinder without stopping the equipment. This completely avoids the cumbersome operation of stopping the machine and disassembling and changing the mold required by traditional technology, greatly shortens the specification changeover time, and is particularly suitable for the production needs of small batches and multiple specifications of products, significantly improving production efficiency and equipment utilization.

[0015] As a preferred technical solution of this utility model, a flared mouth 71 is provided at the upper end of the feed pipe 7.

[0016] As a preferred technical solution of this utility model, the speed-adjustable motor 8 is a DC brushed motor.

[0017] As a preferred technical solution of this utility model, the cutting blade 10 is made of stainless steel.

[0018] As a preferred technical solution of this utility model, the bottom guide part includes a bottom mounting groove 14 and a trapezoidal guide frame 15; the bottom mounting groove 14 is opened in the middle of the base frame 1, and the trapezoidal guide frame 15 is detachably installed in it. The inclined part of the trapezoidal guide frame 15 is covered with a smooth material layer, and the bottom of the trapezoidal guide frame 15 is made of iron. A magnet is fixed at the bottom of the bottom mounting groove 14, and the trapezoidal guide frame 15 is spliced ​​and installed by magnetic attraction.

[0019] The working principle of this invention is as follows: During use, the molecular sieve mixture to be formed (such as a mixture of powder and binder) is added to the device through the feed pipe. The flared design at the upper end of the feed pipe helps reduce material spillage during feeding. The material enters the extrusion cylinder through the feed inlet, and the screw conveyor drive (usually connected to an external power source) is activated. The drive motor drives the screw conveyor (such as a screw) inside the extrusion cylinder to rotate. The rotating screw conveyor exerts a powerful squeezing and conveying force on the material, compacting it and propelling it forward (downward) along the inner cavity of the extrusion cylinder. Based on the required particle diameter, the controller sends a command to the right-side stepper motor, which then starts, precisely driving the connecting shaft and mounting plate below it to rotate. Four baffles are evenly distributed around the circumference of the mounting plate, each with a forming channel of a different diameter. The stepper motor precisely rotates and positions the selected baffle with the target diameter forming channel directly below the opening at the bottom of the extrusion cylinder. The baffle (made of hard rubber) rotated to the working position has its upper surface slightly higher (e.g., 1 mm higher) than the bottom surface of the extrusion cylinder. Under the continuous downward squeezing force of the screw conveyor, the hard rubber upper surface of the baffle is compressed, producing a slight elastic deformation, thus tightly fitting against the edge of the bottom opening of the extrusion cylinder, forming an effective dynamic seal to prevent material leakage from the contact surface. Under high pressure, the compacted and propelled material can only be extruded through the forming channel on the baffle currently located below the opening of the extrusion cylinder. After the material passes through the forming channel of a specific diameter, it forms a continuous and uniform cylindrical strip. The shaped particles, cut into this strip, fall naturally under gravity and land in the bottom guide section located in the middle of the base frame. The bottom guide section consists of a bottom mounting groove and a trapezoidal guide frame that is detachably installed within it. The inclined surface of the trapezoidal guide frame is covered with a smooth material layer to effectively reduce the frictional resistance of the particles sliding down. The particles slide down the inclined surface of the trapezoidal guide frame and are guided to a preset collection area (such as a hopper or conveyor belt). The trapezoidal guide frame is quickly and easily installed and removed by the magnetic attraction between its iron bottom and the magnet fixed to the bottom of the bottom mounting groove, facilitating cleaning and maintenance.
