Description

Technical Field

[0001] The utility model belongs to the technical field of molecular sieve adsorbent preparation, and particularly relates to an extruder for preparing molecular sieve adsorbents. Background Art

[0002] As an important industrial material, molecular sieves are widely used in many fields such as petroleum refining, petrochemical industry, and chemical fertilizers. At present, an extruder is a key equipment in the production of molecular sieves, which is used to extrude raw materials into the required strip-shaped molecular sieves through extrusion molding. However, traditional extruders have problems such as low bar extrusion efficiency and unstable product quality during the production process.

[0003] Existing bar extruders usually adopt a screw propulsion method to extrude the mixed raw materials through a screen and a heating device for forming. However, in the process of using this method, the raw materials are prone to deposition and insufficient crushing, resulting in caking and hardening. Due to the caking and hardening of the raw materials, the extruder often gets stuck during operation, and the raw materials are easily adhered to the bottom of the pipeline, reducing the extrusion stability and product uniformity. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an extruder for preparing molecular sieve adsorbents to prevent caked and hardened raw materials from entering the extrusion assembly, achieving the effect of improving the production rate.

[0005] In view of this, the utility model provides an extruder for preparing molecular sieve adsorbents, which includes a base and an extrusion assembly arranged on the base, and further includes: a stirring assembly capable of stirring materials, a feeding assembly connecting the stirring assembly and the extrusion assembly, and the feeding assembly is connected to the stirring assembly and can supply raw materials to the stirring assembly.

[0006] In this technical solution, the raw materials enter the feeding assembly, the feeding assembly transports the raw materials to the stirring assembly, the stirring assembly stirs the raw materials, and the raw materials enter the extrusion assembly for extrusion into strips. During the transportation and storage of the raw materials, caking and hardening may occur. By arranging a stirring assembly in front of the extrusion assembly, the utility model can stir and break the materials that may cake and harden during the transportation and storage process, improving the quality of the finished products extruded by the extrusion assembly.

[0007] In the above technical solution, further, the stirring assembly includes a first support frame, a stirring tank is arranged on the first support frame, the stirring tank is erected above the extrusion assembly, a first feeding port is arranged at the top of the stirring tank, a first discharge pipe is arranged at the bottom of the stirring tank, the discharge pipe is connected to a pressurizing assembly, a first motor is fixedly arranged on the outer wall of the stirring tank, and the output end of the first motor passes through the side wall of the stirring tank and is connected to a stirring unit, and the stirring unit stirs the raw materials.

[0008] In the above technical solution, further, the stirring unit includes a stirring roller rotatably arranged in a stirring tank. The stirring roller is sleeved with stirring blades, and a plurality of fixing rods are connected between the stirring blades and the stirring roller.

[0009] In this technical solution, raw materials enter the stirring tank from the first feeding port. The first motor drives the stirring roller to rotate, and the stirring roller drives the stirring blades to rotate through the fixing rods. The raw materials in the stirring tank are stirred by the rotation of the stirring blades.

[0010] In the above technical solution, further, the stirring blade includes a first stirring blade fixedly arranged on a first fixing rod. A second stirring blade is sleeved inside the first stirring blade, and the second stirring blade is fixedly arranged on a second fixing rod corresponding to the opposite helix of the first stirring blade.

[0011] In this technical solution, the first stirring blade is at the outer circle and the bottom is attached to the inner wall of the stirring tank. The second stirring blade is at the inner circle, and the spiral direction of the second stirring blade is opposite to that of the first stirring blade. During the rotation of the entire stirring blade, the first stirring blade pushes the raw materials at the bottom of the stirring tank towards the first discharge pipe, while the second stirring blade pushes the raw materials in the opposite direction, and the raw materials are circulated and stirred in the stirring tank, achieving a sufficient stirring effect on the materials.

[0012] In the above technical solution, further, the stirring tank includes a partition plate slidably arranged in a movable groove, and the movable groove is arranged on the first discharge pipe.

[0013] In this technical solution, when the raw materials enter the stirring tank, the partition plate slides inwards along the movable groove. After the raw materials in the stirring tank are stirred, the partition plate is slid outwards along the movable groove manually, and the raw materials enter the extrusion assembly from the first discharge pipe. The extrusion assembly is a well-known prior art and will not be elaborated here.

[0014] In the above technical solution, further, the feeding component includes a transport pipe. One side of the transport pipe is erected on a second support frame, and the other side is erected on the top of the stirring tank. The side of the transport pipe away from the stirring tank is connected with a second hopper with an upward opening. The transport pipe is connected to the stirring tank through a second discharge pipe. The second discharge pipe is arranged vertically. A second motor is fixedly arranged at one end of the transport pipe, and the output end of the second motor passes through the transport pipe and is coaxially connected with a transport roller. The transport roller is rotatably arranged in the transport pipe along the length direction of the transport pipe, and transport blades are spirally arranged on the outer wall of the transport roller.

[0015] In this technical solution, the raw materials are poured into the second feeding hopper, and the second motor is started to drive the rotating rollers in the conveying pipe. The spiral conveying blades fixedly arranged on the outer wall of the rotating rollers push the raw materials towards the second discharge pipe until they leave the conveying pipe through the second discharge pipe and enter the mixing tank.

[0016] In the above technical solution, further, a partition grid is further included, and the partition grid is arranged at the opening of the second feeding hopper.

[0017] In this technical solution, the interval between the bars on the partition grid is between two centimeters and three centimeters. The partition grid preliminarily screens out larger agglomerated particles in the raw materials to avoid blockage in the conveying pipe.

[0018] In the above technical solution, further, a cutting assembly is further included. The cutting assembly includes a third support frame fixedly arranged on the base. A third motor is fixedly arranged on the third support frame. A protective cover is fixedly arranged on the third support frame. A rotating shaft is rotatably arranged on the protective cover.

The output end of the third motor is coaxially connected to a second sprocket, and a chain is drivingly connected between the first sprocket and the second sprocket.

[0019] In this technical solution, the third motor drives the second sprocket to rotate. The second sprocket drives the first sprocket to rotate through the chain. The first sprocket drives the rotating shaft to rotate, and the rotating shaft drives the cutter head at the end to rotate. The rotation trajectory of the cutter head passes through the discharge port of the extrusion assembly, and the cutter head periodically cuts the finished products generated by the extrusion assembly to avoid the finished products being too long and affecting the quality of the finished products.

[0020] The beneficial effects of the present utility model are as follows:

[0021] 1. By arranging a mixing assembly, the raw materials in the mixing tank are mixed by the rotation of the mixing blades. During the rotation of the entire mixing blades, the first mixing blade pushes the raw materials at the bottom of the mixing tank towards the first discharge pipe, while the second mixing blade pushes the raw materials in the opposite direction, and the raw materials are circulated and mixed in the mixing tank, achieving a sufficient mixing effect on the materials.

[0022] 2. By arranging a feeding assembly, the raw materials are poured into the second feeding hopper, and the second motor is started to drive the rotating rollers in the conveying pipe.
