Problems solved by technology

However, a large number of existing cooking pots cannot be installed with a built-in pot loader due to structural limitations. The diameter of the upper opening of the cooking pot is 700 mm, and the diameter of the pot body is more than 3600 mm. Not spread in the pot, the filling rate is low, and the potting time is long

Embodiment 1

[0027] Such as Figure 1-3 As shown, an external pot loader for the papermaking industry includes a fixed cylinder 1, the lower end of which is provided with a vertically lifting movable cylinder 2, and the outer wall of the fixed cylinder 1 is connected with a vertical lifting cylinder 3, which can be lifted and lowered. The lower end of the cylinder 3 is connected with the upper end of the movable cylinder 2, and the upper end of the movable cylinder 2 is slidably sleeved on the outside of the lower end of the fixed cylinder 1. A supporting frame is fixed in the movable cylinder 2, the upper end of the supporting frame is provided with a distributing cone 4, and the lower end is provided with a cloth assembly driven by a motor 5, the supporting frame includes several hollow supporting rods 6, and one end of the supporting rod 6 is connected to the movable cylinder 2. The inner wall of the shaft 7 is connected, and the other end is connected with the motor 5. The electric wir...

Embodiment 2

[0030] Such as Figure 4 As shown, a cooking pot includes the external pot loader described in Embodiment 1, and also includes a pot body 11, the upper end of the pot body 11 is provided with an openable pot cover 12, and the pot cover 12 and the upper end of the pot body 11 Connected by flanges, or other openable connection structures, the lower end of the movable cylinder 2 is placed above the pot cover 12, the upper end of the fixed cylinder 1 is connected with the feeding hopper 13, and several air outlets are arranged on the pot body 11 14. The air outlet 14 is located near the bottom of the pot body 11 .

Embodiment 3

[0032] A method for using the cooking pot described in embodiment 2, comprising the following steps:

[0033] (1) Open the pot cover 12, the lifting cylinder 3 is stretched, and the movable cylinder 2 is moved down to be placed in the pot body 11, the starting motor 5 drives the cloth blade 8 to rotate, and the steam propulsion nozzle 9 ejects steam to the cloth blade 8, and the steam spray The direction is consistent with the direction of rotation of the cloth blade 8;

[0034] (2) Feed the tablet 15 into the fixed cylinder 1 through the feed hopper 13, the tablet 15 falls on the distribution cone 4 through the fixed cylinder 1, and the distribution cone 4 divides the tablet 15 to the distribution blade 8, and the steam pushes it The steam ejected from the nozzle 9 preheats and soaks the material sheet 15, which increases the density of the wood chips. Open, improve the pot loading capacity and pot loading efficiency, reduce the subsequent preheating heating time, and improv...

Abstract

The invention provides an external digester charger for papermaking industry, a digester and a use method of the digester. The external digester charger comprises a fixed cylinder, the lower end of the fixed cylinder is provided with a vertically lifting movable cylinder, the movable cylinder is internally provided with a support frame, the upper end of the support frame is provided with a material distribution cone, and the lower end of the support frame is provided with a material distribution assembly driven by a motor; and a plurality of steam propelling nozzles are arranged on the inner wall of the movable cylinder corresponding to the material distribution assembly in the circumferential direction, the steam propelling nozzles are arranged downwards in an inclined mode, the steam spraying direction is consistent with the rotating direction of the material distribution assembly, and a steam annular pipe communicated with the steam propelling nozzles is arranged on the outer wall of the movable cylinder. The digester charger is mounted outside the digester and is not limited by the structure of the digester, and the digester charging rate of the digester is increased.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to an external pot loader, a cooking pot and a use method thereof for the papermaking industry. Background technique [0002] The built-in pot loader is an important part to improve the pot loading efficiency of wood raw materials and paper cooking pots. It is a circular steam distribution chamber with several inclined and consistent nozzles evenly distributed on the lower end. The steam ejected from the nozzles is used to drive the material sheet to rotate rapidly. And fall, and evenly cover the space in the pot, which has the functions of quickly and evenly distributing the sheets, improving the pot loading capacity and pot loading efficiency. [0003] However, the built-in pot loading device is located at the upper neck of the cooking pot and below the pot loading ball valve. It is widely used in newly added cooking pots in recent years. Using this device can improv...
