Description

Technical Field

[0001] The present application relates to the technical field of material conveying, and in particular to a discharging device and a screw machine equipment. Background Art

[0002] Screw machines have important applications in many production and processing fields, such as chemical industry and new energy production. Twin screw machines are one type of screw machine. Currently, the discharge method of twin screw machines is mostly axial direct discharge. When there are more than two screw machines, the axial discharge direction will limit the arrangement of the screw machines, so that adjacent screw machines can only be arranged in the axial direction, which greatly increases the floor space and increases the equipment installation and maintenance costs. Utility Model Content

[0003] In view of this, the purpose of the present application is to provide a discharging device and a screw machine equipment to solve the problem that the existing axial discharging design increases the installation and maintenance costs of the multi-screw machine equipment.

[0004] In order to achieve the above technical purpose, the present application provides a discharging device, comprising a first cylinder and a second cylinder;

[0005] The first cylinder is stacked on the second cylinder and forms an angle with the second cylinder;

[0006] A discharge port is provided at the bottom of the first cylinder;

[0007] A first screw conveying module is provided in the first barrel;

[0008] The first screw conveying module includes a reverse pressure-feeding unit, a pressure-feeding release unit and a first forward pressure-feeding unit;

[0009] The first forward pressure-feeding unit, the pressure-feeding release unit, and the reverse pressure-feeding unit are coaxially connected in sequence;

[0010] The pressure-feeding release unit is located in the area above the discharge port;

[0011] The top of the second cylinder is provided with a feed port connected to the discharge port;

[0012] A second screw conveying module is disposed in the second cylinder;

[0013] The second screw conveying module includes a second forward pressure conveying unit.

[0014] Furthermore, the first cylinder and the second cylinder are vertically distributed.

[0015] Furthermore, the first cylinder and the second cylinder are interlocked.

[0016] Furthermore, a first notch is formed at the bottom of the first cylinder;

[0017] The first notch runs through both sides of the first cylinder;

[0018] The first notch is connected to the first cylinder body through a communication port to form the discharge port;

[0019] A second notch is formed on the top of the second cylinder;

[0020] The second notch runs through both sides of the second cylinder;

[0021] The connecting opening of the second notch and the interior of the second cylinder forms the feed opening;

[0022] The first notch and the second notch can be engaged with each other so that the discharge port is directly connected to the feed port.

[0023] Furthermore, a sealing ring is provided between the first notch and the second notch.

[0024] Furthermore, first connecting flanges are formed around both ends of the first cylinder.

[0025] Furthermore, second connecting flanges are provided around both ends of the second cylinder.

[0026] Furthermore, there are two first screw conveying modules, which are arranged side by side.

[0027] Furthermore, there are two second screw conveying modules, which are arranged side by side.

[0028] The present application also discloses a screw machine device, wherein the screw machine device is applied with the above-mentioned discharge device.

[0029] It can be seen from the above technical scheme that the discharge device designed in this application has a discharge port at the bottom of the first cylinder, and a feed port vertically connected to the discharge port at the top of the second cylinder. The first screw conveying module in the first cylinder is composed of a first forward pressure-feeding unit, a pressure-feeding release unit and a reverse pressure-feeding unit coaxially connected in sequence. The first forward pressure-feeding unit conveys the material forward, and the material is reversely conveyed by the reverse pressure-feeding unit when it is conveyed to the reverse pressure-feeding unit. The forward pressure-feeding unit and the reverse pressure-feeding unit work together to squeeze the material so that the material converges in the pressure-feeding release unit. The pressure-feeding release unit throws the material out through the rotating centrifugal force, so that the material is smoothly discharged from the discharge port of the first cylinder, and the material enters the feed port of the second cylinder through the discharge port. At the same time, the second forward pressure-feeding unit in the second cylinder can send the input material away, so that the material of the first cylinder can be vertically discharged into the second cylinder and transported away. When this design is applied to multi-screw machine equipment, it can realize the upper and lower stacking setting of the screw machine, reduce the equipment installation and maintenance costs, and vertical material transportation, small transfer distance, no blockage, no residue, and higher efficiency.
