Powder adding machine for ultra-long heating pipe of soil heater

Abstract

The invention discloses a powder adding machine for an ultra-long heating pipe of a soil heater. After an electric heating pipe is hoisted to a vertical position through a hoisting mechanism at the top of a tower, the upper end of the electric heating pipe is extended into a guide pipe at the bottom end of a powder storage box and is clamped tightly through hoops. Groove plates on a plurality of layers of platforms simultaneously clamp the electric heating pipe through limiting grooves, motors on each layer of the platforms cooperate with drive grooves through eccentric shafts to drive the electric heating pipe to move and oscillate back and forth in the horizontal direction through the groove plates, and automatic powder filling, shaking and compacting operations can be carried out on a 12m-18m ultra-long single-ended heating pipe of a heater for soil repairing. The structure is simple, the operation is convenient, and the cost is low.

Description

technical field [0001] The invention relates to a powder feeder for super-long heating pipes of soil heaters. Background technique [0002] With the rapid development of social economy, science and technology, people's living and living standards are getting higher and higher. At the same time, pollutants generated by human production and living activities are discharged through the soil, causing irreversible pollution to the soil, which must be repaired through professional measures. Purification, heat treatment is a commonly used method of soil remediation; in order to completely repair the soil and prevent blind spots in the repair, the heating device in the heat treatment method needs to heat the soil at a sufficient depth, so the length of the electric heating tube used for soil remediation is usually It can reach 12m-18m, and only single-ended electric heating tubes can be used. The traditional powder feeder used to fill electric heating tubes with magnesium oxide powd...

[0002] With the rapid development of social economy, science and technology, people's living and living standards are getting higher and higher. At the same time, pollutants generated by human production and living activities are discharged through the soil, causing irreversible pollution to the soil, which must be repaired through professional measures. Purification, heat treatment is a commonly used method of soil remediation; in order to completely repair the soil and prevent blind spots in the repair, the heating device in the heat treatment method needs to heat the soil at a sufficient depth, so the length of the electric heating tube used for soil remediation is usually It can reach 12m-18m, and only single-ended electric heating tubes can be used. The traditional powder feeder used to fill electric heating tubes with magnesium oxide powder can only fill, oscillate, and compact electric heating tubes with a length of 2m-3m. , cannot adapt to the requirements of powder filling, oscillation and compaction of long-length single-ended electric heating tubes in soil remediation heaters
