High-voltage explosion-proof electric heater

Abstract

This utility model discloses a high-pressure explosion-proof electric heater, including an electric heater housing, a water pipe connector conductively connected to the surface of the electric heater housing, support legs symmetrically welded to the bottom of the electric heater housing, an electric heating rod installed at the opening of the electric heater housing, and a mounting base fixedly connected to the end of the electric heating rod. The support legs have symmetrically opened guide holes on their surfaces, and assistive components are inserted into the surfaces of the support legs. The assistive components are inserted into the surfaces of the support legs, and guide rods are inserted through the guide holes of the support legs. Casters A and B at both ends provide auxiliary support. When assembling the electric heating rod relative to the electric heater housing, the bottom of the mounting base engages with the limiting groove of the base support. Pushing the mounting base horizontally causes casters A and B to roll relative to the ground, and the guide rods to slide relative to the support legs. This makes assembly and disassembly easier, reduces worker fatigue, and improves work efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of electric heater technology, specifically relating to a high-voltage explosion-proof electric heater. Background Technology

[0002] An electric heater is an electrical appliance that uses electrical energy to achieve a heating effect. It is small in size, has high heating power, is widely used, adopts intelligent control mode, has high temperature control accuracy, and can be networked with a computer.

[0003] A search revealed a novel high-pressure explosion-proof electric heater with patent publication number CN221151589U. The heater includes a heater body with an inlet pipe at its top and an outlet pipe at the other end. A filter structure is installed on the inlet pipe. The filter structure includes a protective shell, an inlet pipe, a connecting pipe, a filter pipe, and a filter assembly. The inlet pipe is located at the top of the protective shell, and the connecting pipe is located at the bottom of the protective shell. The connecting pipe and the inlet pipe are connected by a flange. The filter pipe is located inside the protective shell and consists of two sets, with both ends of the two sets connected to the inlet pipe and the connecting pipe, respectively. Two filter assemblies are also provided and installed on the connecting pipe. This invention provides a structurally sound and simple method for filtering media.

[0004] In current technologies, common high-voltage explosion-proof electric heaters have heating rods inserted inside the heater housing. However, when the heating rods are inserted into the heater housing, there is no external support structure. As a result, the heating rods are relatively heavy during assembly and disassembly, leading to a large workload for maintenance personnel and inconvenience in operation. Therefore, it is necessary to design a high-voltage explosion-proof electric heater to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a high-voltage explosion-proof electric heater to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure explosion-proof electric heater, comprising an electric heater housing, a water pipe connector connected to the surface of the electric heater housing, support legs symmetrically welded to the bottom of the electric heater housing, an electric heating rod installed at the opening of the electric heater housing, and a mounting base fixedly connected to the end of the electric heating rod. The support legs are provided with guide holes symmetrically opened on their surfaces, and an assist component is inserted into the surface of the support legs.

[0007] The power assist assembly includes a guide rod inserted through the guide hole, a support base fixedly connected to one end of the guide rod, a base welded to the surface of the support base, a limiting groove formed on the surface of the base, and a caster A fixedly connected to the bottom of the support base.

[0008] Preferably, a support plate is welded to the other end of the guide rod, and a caster B is installed at the bottom of the support plate.

[0009] Preferably, a traction frame is welded to the outer surface of the mounting base, and the surface of the traction frame is provided with anti-slip texture.

[0010] Preferably, the bottom of the mounting base engages with the limiting groove on the surface of the base, and the surface of the support leg has a through hole.

[0011] Preferably, protective components are symmetrically installed on the outer wall of the electric heater housing, and the protective components include reinforcing plates fixedly connected to the surface of the electric heater housing.

[0013] Preferably, the protective frame is arranged parallel to the outer side of the electric heater housing, and a protective gap is provided between the protective frame and the electric heater housing.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The outriggers are fitted with assistive components, and guide rods are inserted through the guide holes of the outriggers. Casters A and B at both ends provide auxiliary support. When assembling the electric heating rod relative to the electric heater housing, the bottom of the mounting base is engaged with the limiting groove of the base. When the mounting base is pushed horizontally, casters A and B roll relative to the ground, and the guide rod slides relative to the outriggers. This makes the assembly and disassembly process easier, reduces the labor intensity of workers, and improves work efficiency.

[0016] 2. Protective components are symmetrically installed on the outer wall of the electric heater housing. The reinforcing plate of the electric heater housing is fixedly connected to the protective frame through the isolation seat. The protective frame plays a good role in isolating and preventing accidental contact, thus improving the safety of use. Attached Figure Description
