Description

Center shaft heat exchange structure of harmless treatment and chemical tank making of livestock and poultry died of diseases and slaughter byproducts

Technical Field

The utility model relates to a beasts and birds of dying of illness and slaughter discarded object innocent treatment ization system jar (reation kettle) axis heat transfer structure. Belongs to the technical field of harmless treatment processing equipment and process for livestock and poultry died of diseases and slaughter wastes.

Background

At present, in harmless treatment and processing projects of livestock and poultry died of illness and slaughtering waste in China, high-temperature high-pressure drying and wet-process system are generally adopted, namely, chemical tank making (jacket reaction kettle) is utilized for treatment, a center shaft structure of the conventional chemical tank making mainly comprises that stirring fins are directly welded on a center shaft (a metal seamless steel pipe) or are fixed on a shaft by using a hoop, in order to increase the heating efficiency in the tank, steam is introduced into a center shaft pipe cavity in the conventional method, materials in the tank are heated through the outer wall of the center shaft, but the diameter of the center shaft is limited after all, the heat exchange area is small, the heat utilization rate is low, so that the time for material chemical preparation and drying is long, and the problem to be solved universally existing in the industry is solved urgently.

In addition, because the tank body of the chemical tank is in a high-temperature and high-pressure state in the working process, the tank body and the center shaft are easy to slightly deform, the deformed center shaft stirring wing tool bit is easy to contact and collide with the inner wall of the tank body, the phenomenon of increasing friction force is particularly large for damage caused by the fact that the center shaft main power motor reducer stops rotating and is easily burnt. In the current production, the solution after the problem is caused is mainly to enter the tank body manually after the shutdown, the stirring wings are trimmed and cut by using a cutting tool, and then the tank body can be normally started again to operate. This also causes unnecessary trouble for normal production, greatly influences the efficiency of work.

The present application will mainly focus on the above two technical problems, developing corresponding solutions.

Disclosure of Invention

An object of the utility model is to solve the not enough of above-mentioned prior art existence, provide a axis heat transfer structure suitable for beasts and birds died of illness and slaughter byproduct innocent treatment ization system jar, this structure has the thermal efficiency height, high-efficient durable, resistance to deformation can the reinforce, operate a great deal of characteristics steady high-efficient, motor long service life. The utility model discloses a this kind of axis structure can make jar internal portion heat transfer area and drying rate obtain promoting by a wide margin, and work efficiency is showing and is improving.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

beasts and birds of dying of illness and slaughter the axis heat transfer structure of byproduct innocent treatment ization system jar, install inside the ization system jar, play stirring and heat transfer effect, the special character lies in that its structure includes:

the main shaft is of a hollow tubular structure, the hollow pipe cavity is used for circulating heat-conducting fluid, and a preset number of through holes are formed in the hollow pipe cavity at intervals in the axial direction;

the drum disc is a hollow drum disc structure formed by connecting two drum sheets in an involutory manner, is provided with a plurality of drum discs, is axially arranged and fixed on the outer wall of the main shaft, and is arranged at a position covering the through hole so as to ensure that the tube cavity of the main shaft is communicated with the inner cavity of the drum disc.

Furthermore, the two drum pieces forming the drum disc are both of spherical crown structures and are welded together in a mirror image manner; compared with a drum sheet with a plane structure, the drum sheet in the shape of the spherical crown has the characteristics of good pressure resistance and strong deformation resistance. The middle part of the drum sheet is provided with an inner sleeve hole for welding with the outer wall of the main shaft, and after the excircles of the two drum sheets are involuntarily welded, a hollow cavity is formed in the drum sheet.

In order to avoid the problem that condensed water generated by the steam inside the central shaft of the chemical tank and in the inner cavity of the drum disc sinks into the bottom of the cavity of the drum disc when encountering cold and can be discharged from the rotary joint at the shaft end until the condensed water level rises to the central position of the main shaft, thereby reducing the heat exchange temperature and area, increasing the load of the main shaft and increasing the energy consumption. The drum disc inner cavity is provided with a fin-shaped partition plate capable of dividing the inner through cavity into a plurality of partition cavities, and the partition cavities are communicated with the middle shaft inner cavity through holes formed in the middle shaft; through the isolation effect of the fin-shaped partition plate, the condensed water in each separated cavity is discharged from the cavity to the cavity of the main shaft along with the change of the position of the cavity, and finally is discharged to the outside through the rotary joint.
