Description

Technical Field

[0001] The utility model relates to the technical field of internal mixers, in particular to an oil injection one-way valve for process oil of an internal mixer. Background Art

[0002] The process oil injection valve of the internal mixer plays a key role in the oil injection system of the internal mixer. When the internal mixer is working, process oil needs to be injected into the internal mixing chamber. The common way of oil injection is to install an oil injection device on the internal mixing chamber. There are many types of oil injection devices for internal mixers. For example, a pressure reducer for reducing pressure and an exhaust valve for exhausting and reducing pressure are fixedly installed on both sides of the reserve oil tank, and an electric telescopic rod and instrument are fixedly installed on the top.

[0003] In some designs, in order to solve the problem that the process oil is easy to flow back into the oil filling valve during bottom oil filling, the unloading door mechanism of the relevant oil filling structure has been improved. The oil filling system of the internal mixer is controlled by the PLC program. The automatic oil weighing system is usually an important part of the PLC. The upper computer transmits the weighing formula to the lower computer and starts the oil weighing operation. After the oil is prepared, the internal mixer receives the oil filling command of the PLC program for automatic oil filling.

[0004] At present, the process oil injection valve of the internal mixer may have various faults during use. For example, when injecting oil at the bottom, the process oil is easy to flow back into the injection valve, affecting the injection effect and production efficiency.

[0005] In order to improve the performance of the process oil injection valve of the internal mixer, it is very important to optimize the design. Improvements can be made in the structure, such as adopting a more reasonable valve channel design to reduce the oil flow resistance and improve the injection efficiency. In addition, the control system structure is relatively complex and the cost is relatively high. Utility Model Content

[0006] In view of the above defects in the prior art, the utility model provides an oil injection one-way valve which can solve the above technical problems and has a relatively simple structure and high safety. The specific technical solution is as follows:

[0007] The invention discloses an oil injection non-return valve for an internal mixer, which comprises an internal mixer body, a mixing chamber arranged at the center of the internal mixer body, a feeding port arranged above the mixing chamber, an oil injection non-return valve arranged at the side wall above the mixing chamber, and the oil injection non-return valve is arranged obliquely on the side wall.

[0008] As a preferred solution of the utility model, the oil injection one-way valve includes a valve body, a valve core and a reset spring. The valve body is provided with an oil injection port which leads into the valve core. A reset spring is installed between the valve core and the valve body. The valve body is located outside the valve core and is provided with a valve cover which seals the valve core. The valve body is located inside the mixing chamber and is provided with a plug, and is provided with a connecting rod which is fixedly connected to the valve core.

[0009] As a preferred solution of the utility model, the valve core is cylindrical, and a cutting groove is provided in the middle of the side wall of the column, and a plurality of ring groove holes are provided at the cylindrical surface of the valve body, and the cutting grooves and the ring groove holes are connected at the cutting groove position of the side wall.

[0010] As a preferred solution of the utility model, a mounting hole is provided at the center of the valve body and the plug, and the connecting rod is installed in the mounting hole. When the side wall of the valve core blocks the oil filling port, the plug can block the oil outlet of the valve body.

[0011] Beneficial effects: The oil injection one-way valve of the utility model can inject process oil directly into the mixing chamber, which is more efficient than the existing oil injection one-way valves in other positions and can effectively prevent oil leakage. After the oil injection is completed, the reset spring can automatically return the valve core to its original position and make the plug block the oil outlet to prevent the rubber raw materials in the mixing chamber from entering the valve body, which can effectively extend the service life of the oil injection one-way valve. The position setting of the one-way valve makes the process oil evenly distributed in the equipment to ensure that the material fully contacts the oil and optimizes the mixing effect; the precise oil injection control can effectively avoid excessive oil injection, thereby reducing resource waste and cost; this structural oil injection one-way valve can prevent process oil leakage, keep the working environment clean, and avoid oil loss and possible safety hazards; the structural design is reasonable, which is convenient for daily inspection, cleaning and maintenance, and reduces maintenance costs and downtime.
