Description

Float glass kiln thermocouple perforating device

Technical Field

The invention relates to the technical field of float glass production equipment, in particular to a punching device for a thermocouple of a float glass kiln.

Background

A float glass production line kiln is an important part of a float glass production line, and the main body of the glass kiln comprises a small furnace, a regenerator, a melting part, a charging opening and a cooling part. The glass kiln has the main function of melting batch materials into qualified molten glass for molding, and the batch materials are heated by natural gas combustion of small furnaces of the glass kiln, so that in order to ensure scientific and reasonable combustion of the molten glass in the glass kiln, thermocouples are required to be arranged at all parts of a kiln main body, and the temperature points of all positions of the glass kiln displayed by the thermocouples are observed so as to control the flame size of each small furnace and melt the molten glass under a scientific and reasonable temperature system. Because the internal temperature of the kiln is higher and is generally in the temperature range of 1200-1590 ℃, the service life of the thermocouple of the kiln generally needs to be replaced more than a year. In particular to a furnace tank bottom galvanic couple, in order to ensure the accuracy of the temperature of the furnace tank bottom, the furnace tank bottom galvanic couple is generally 50mm higher than the tank bottom, and the tank bottom galvanic couple needs to be replaced by a new galvanic couple for more than one year due to the convection washing of glass liquid at the tank bottom. The tank bottom galvanic couple is installed in the tank bottom brick, the ceramic pipe of the galvanic couple body penetrates through the tank bottom layer of the whole kiln, the diameter of the ceramic pipe of the galvanic couple is 10mm, the diameter of a galvanic couple through hole at the tank bottom is generally 14mm, a gap between the galvanic couple ceramic pipe and the tank bottom through hole is filled with high-temperature glass liquid and solidified, when the galvanic couple at the tank bottom is replaced, the old galvanic couple ceramic pipe needs to be taken out firstly (after a galvanic couple wire is burnt out, a damaged galvanic couple wire can be directly taken out after a galvanic couple cover is opened), and the galvanic couple ceramic pipe is difficult to take out or almost impossible to take out due to the fact that the ceramic pipe and the glass liquid in the galvanic couple through hole are solidified together.

Disclosure of Invention

The invention aims to provide a punching device for a thermocouple of a float glass kiln, which can realize punching at the bottom of the kiln so as to facilitate replacement of the thermocouple.

The technical scheme adopted by the invention for solving the technical problems is as follows:

a float glass kiln thermocouple perforating device comprises a horizontal fixing frame, wherein the fixing frame is connected with a hanging frame at the bottom of a kiln; a vertical mounting rack is arranged in the fixed frame, a screw rod transmission mechanism is arranged on the mounting rack, and an operating handle is arranged on the screw rod transmission mechanism; the punching device also comprises a water drill rod and a pneumatic motor, the pneumatic motor is vertically arranged, and the side part of the pneumatic motor is fixedly connected with a movable nut of the screw rod transmission mechanism; the water drill rod is connected with a rotating shaft of the pneumatic motor; a drill bit is arranged at the top end of the water drill rod; the inside of the water drill rod is provided with a water inlet pipe and a water return pipe which are used for connecting cooling water.

The invention has the beneficial effects that when in use, the fixing frame of the device is fixed on a hanging frame at the bottom of a kiln at a position needing punching through a bolt, the pneumatic motor is started, and the operating handle is rotated at the same time, so that the pneumatic motor is lifted, the water drill bit is driven to upwards impact and drill the bottom of the kiln, the purpose of punching is realized, the thermocouple prepared in advance is immediately inserted into the bottom hole of the kiln after the bottom hole of the kiln is punched, and finally, the newly replaced thermocouple is fixed.
