Novel production process of paraffin wax continuous forming machine

Abstract

The invention discloses a novel production process of a paraffin wax continuous forming machine, which solves the problems by rationalizing and automating a process flow, shortening a cycle and improving the product quality. The particularly-adopted novel process comprises the following processes: a precooling process, a wax injecting process, a transmitting process, a condensing process, and automatic packaging; wherein the precooling process comprises a warm water closed circulation cooling process, a constant-temperature water closed circulation heat preservation process and a hot air blowing process; the wax injecting process comprises the steps of keeping the precooled liquid wax in a constant temperature and pressure, automatically weighing the wax and injecting the wax into wax discs periodically; the transmitting process comprises the steps of controlling an active power output by a main motor and predicatively controlling an operation state of a main chain; and the condensing process comprises the steps of setting and controlling the area of an evaporator, the evaporating temperature of a refrigerant, the air volume conveyed by an air cooler and the cold energy of a cold chamber. The novel production process of the paraffin wax continuous forming machine has the advantages of: reasonable process flow, optimized parameters, short process cycle, high automation degree, obvious effects of saving energy and reducing emission and high wax injection accuracy.

Description

technical field [0001] The invention relates to a production process of a paraffin wax continuous molding machine, in particular to a new production process of the paraffin wax continuous molding machine. Background technique [0002] The traditional paraffin continuous molding machine achieves the design capacity under the premise of the annual limit effective working time - 8400 hours. Taking the traditional paraffin continuous molding machine with an annual output of 30,000 tons / set as an example, the process flow and main process parameters are as follows: [0003] (1) Pre-cooling process: (paraffin melting point range 54℃~85℃) [0004] Warm water for pre-cooling (44℃~45℃ for conventional wax, 55℃~65℃ for special wax) → steam heating in special water tank (water consumption: 1 ton / time, steam consumption: 200kg / h) → warm water / cold water pipe Shell heat exchanger (cold water consumption 8t / h~10t / h)→water pump (motor power: 4.4KW, lift 32m)→liquid wax / warm water shell a...

AI Technical Summary

Problems solved by technology

[0016] 2. High energy consumption and low efficiency

[0017] 3. Low level of automation

Manual or semi-automatic operation: the pre-cooling system is working, and the water and steam valves of the special water tank need to be manually closed; the quality accuracy of wax injection depends on the manual cam to adjust the reserve in the cylinder, and each adjustment requires a condensation cycle, usually 3 to 5 times Adjustment, and frequent adjustments are required; wax blocks produced during the adjustment period can only be treated as unqualified products; packaging needs to be manually weighed on a scale with broken pieces, and automatic packaging cannot be implemented

No automatic control system: Since there are no safety precautions for the main chain operation, and only a single-function post-alarm is configured, chain breakage, wax plate damage, and even human injury often occur. After each accident, it needs to be shut down for 2 to 3 days. It not only loses effective working time, but also increases the cost of accessories and maintenance, and reduces the life of the equipment; without an automatic control system, it is impossible to track and automatically adjust the process parameters, which directly affects the quality, accuracy and cost of the finished paraffin wax
