Description

Kneading sealing anti-blocking type feeding steaming and boiling pipe

Technical Field

The utility model relates to the technical field of cooking pipes, in particular to a kneading sealing anti-blocking type feeding cooking pipe.

Background

The horizontal tube type continuous digester is a high-temperature and quick digester, the raw materials are heated to 170-190 ℃ by direct steam after passing through the digester tube of the digester, the digester period is shortened, and the digester time is between 10-50min according to the requirements of raw materials, dipping conditions and pulping quality. The current continuous digester generally puts the raw materials to be cooked into a cooking tube for cooking, because the high-temperature steam flows through the cooking tube and the pressure in the cooking tube is high, the materials and the steam are easily sprayed out from a feed inlet, the quality of cooking can be affected, and the potential safety hazard in the cooking process can be increased.

There are several sealing feeding devices on the market at present, including spiral sealing feeding, reducing spiral feeding, piston spiral feeding, etc., and these devices have advantages and disadvantages, and the kneading pretreatment before steaming at present is a separate process, and generally a separate kneading machine is used for the kneading pretreatment, so there is a lack of a device capable of integrating continuous sealing feeding and performing the kneading pretreatment before feeding in the prior art.

The utility model provides a packing sealing cooking pipe convenient and quick to feed, and aims to provide a packing sealing cooking pipe convenient and quick to feed, solve the problems of low feeding efficiency of the cooking pipe and inconvenient assembly and adjustment of a pipeline, and have a relatively simple structure. But the sealing effect is poor, and the cooperative material kneading pretreatment cannot be realized.

The patent number CN104477583A proposes a cooking tube feeding device, and the cooking raw materials and steam of the cooking tube feeding device cannot be sprayed back, so that the cooking quality is improved, and the safety of the cooking process is ensured. The feeder is a variable-diameter and variable-pitch spiral cone, is driven by a screw rod with large torque, pushes a block made of plant straws into a cooking pipeline, and is used for sealing the vapor pressure in the cooking pipeline. In order to ensure the density of the materials, a high-power motor is required to drive the screw rod to generate enough driving force. In particular, during the extruder, two thirds of the energy is consumed and the surface of the cone wears rapidly due to the strong thrust of the propeller, resulting in maintenance and replacement of the cone and propeller, which consumes a lot of energy and also increases maintenance and manufacturing costs.

The patent number CN103015245A proposes a plant fiber continuous steaming piston type screw feeder, which utilizes the impact force of reciprocating motion of a piston to extrude a material plug, thereby saving labor, obtaining better extrusion effect, ensuring better quality and efficiency of the material plug, greatly reducing the motor power of the feeder compared with a motor of a conventional feeder, and having obvious electricity saving effect. But the piston can harden the material under the impact of the piston, which is easy to cause blockage, and the material can not be better contacted with the liquid medicine fully after entering the cooking tube, thereby influencing the quality of the produced product.

In summary, it is clear that the prior art has inconvenience and defects in practical use, so that improvement is needed.
