Embodiment 1

[0024] Embodiment 1: as figure 1 As shown, the wax removal kiln of this embodiment includes the connected first tunnel kiln 1 and the second tunnel kiln 3, and the product is preheated to 180°C to 300°C through the second tunnel kiln 3 and kept warm for a certain period of time before being pushed into the first tunnel kiln 1. By adding the second tunnel kiln 3, it can ensure that the product has sufficient heat preservation time, so as to avoid subsequent product waxing and bursting. Wherein, the preheating temperature range is any temperature value between 180°C and 300°C, such as 180°C, 181°C, 182°C, 183°C...298°C, 299°C, 300°C, etc.

Embodiment 2

[0025] Embodiment 2: as figure 1 As shown, one end of the first tunnel kiln 1 is the product input end and is provided with the first propeller 2, and the other end of the first tunnel kiln 1 is the product output end; also includes the second tunnel kiln 3, the second tunnel kiln 3 The product output end communicates with the product input end of the first tunnel kiln 1 , and the second propeller 6 is installed at the product input end of the second tunnel kiln 3 . The heat preservation temperature of the product in the second tunnel kiln 3 remains basically the same as the temperature of the low-temperature section of the first tunnel kiln 1, and an independent heater can be used for heating and heat preservation. The channel is communicated with the furnace bottom channel of the low temperature section 10 of the first tunnel kiln 1 through the induced air channel 4, and the furnace bottom hot air flow of the first tunnel kiln 1 is introduced to the furnace bottom of the sec...

Abstract

The invention relates to an energy-saving environmentally-friendly de-waxing kiln. The de-waxing kiln comprises a first tunnel kiln body and a second tunnel kiln body, wherein the first tunnel kiln body and the second tunnel kiln body communicate with each other; a product is preheated to 180-300 DEG C through the second tunnel kiln body and then is pushed to the first tunnel kiln body after heat preservation is performed for certain time. The tunnel kiln bodies are additionally arranged on the original basis, the product is subjected to pre-heating and heat preservation in the first place, original low-temperature segment heat preservation time is prolonged, and high-temperature combustion and complete de-waxing processing are performed after heat preservation is performed; and in the pre-heating heat preservation (low-temperature semi-de-waxing) process, it can be well guaranteed that the temperature of a de-waxing product is not raised in a low-temperature range, therefore it is guaranteed that the de-waxing product cannot be cracked, the production cost is greatly saved, the loss is lowered, and huge economic benefits are achieved. Only structural transformation on the basis of an existing tunnel kiln is needed, the overall structure is simple, the transformation cost is low, and the energy-saving environmentally-friendly de-waxing kiln is easy to popularize.

Description

technical field [0001] The invention relates to the technical field of electronic ceramic production equipment and facilities, in particular to a tunnel kiln used for removing paraffin wax in the electronic ceramic production process. Background technique [0002] Electronic ceramics refer to ceramics that can use electricity and magnetic properties in the electronics industry. Electronic ceramics are ceramics with new functions obtained through precise control of surface, grain boundary and size structure. It can be widely used in energy, household appliances, automobiles, etc. [0003] Known special ceramic manufacturing technologies, such as isostatic pressing, dry pressing, hot injection molding, grouting molding, injection molding, in-situ injection molding, etc., are now the most economical and most widely used in industrial mass production. The hot press injection molding and injection molding processes are the most popular. The hot press injection molding process in...
