Description

Technical Field

[0001] The utility model relates to the technical field of power regulating cabinets, in particular to an anti-dry burning component of a power regulating cabinet for an air separation electric heater. Background Art

[0002] The air separation electric heater is an important equipment of the air separation unit. It is mainly used to heat the liquid air to the evaporation temperature, so that it becomes gaseous air suitable for air separation. When the air separation electric heater is used, it is usually controlled by a power control cabinet.

[0003] However, when the molecular sieve is in the cold blowing stage during the use of the air separation device, the thyristor in the electric heater power control cabinet has a breakdown phenomenon, so it needs to be improved. In addition, when the power control cabinet is in use, personnel need to explore the interior for inspection and maintenance, so it needs to be improved. Utility Model Content

[0004] The utility model aims to provide an anti-dry burning component for a power regulating cabinet of an air separation electric heater, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: an air separation electric heater power adjustment cabinet anti-dry burning assembly, including a power adjustment cabinet body, a first mounting plate and a second mounting plate,

[0006] The two ends of the inner wall of the power control cabinet body are welded with a guide rail 1 and a guide rail 2;

[0007] An air intake pipe is embedded and fixed on the side end surface of the power regulating cabinet body, and an air intake fan is arranged in the air intake pipe;

[0008] A driving mechanism is installed on the rear end surface of the power regulating cabinet body, and a screw rod is arranged on the output shaft of the driving mechanism;

[0009] The guide frames are welded on the mounting plate 1 and the mounting plate 2, and the guide frames are mounted on the screw rod through threads;

[0010] A mounting frame is welded on the top surface of the second mounting plate;

[0011] There are two mounting frames in total, and the circuit breakers and overvoltage protectors are respectively sleeved in the two mounting frames.

[0012] Preferably, a mounting base is welded to the bottom end surface of the power control cabinet body, and a mounting block is welded to the bottom end surface of the mounting base. The power control cabinet body can be installed and supported by the cooperation of the mounting base and the mounting block.

[0013] Preferably, an outlet pipe is embedded and fixed at one end of the power control cabinet body away from the air inlet pipe, and the outlet pipe is in gas communication with the power control cabinet body. The outlet pipe is in gas communication with the power control cabinet body, so that the gas entering the power control cabinet body can be discharged through the outlet pipe.

[0014] Preferably, the mounting plate 1 is slidably sleeved in the guide rail 2, and the mounting plate 2 is slidably sleeved in the guide rail 1. Installation and position limiting can be performed by sliding the mounting plate 1 and the mounting plate 2 in the guide rail 2 and the guide rail 1.

[0015] Preferably, there are four guide rails 1 and 2 in total, and the four guide rails 1 and 2 are distributed in a rectangular array relative to the power control cabinet body. Since there are four guide rails 1 and 2 in total, guide rails 1 and 2 can install and limit mounting plate 1 and mounting plate 2.

[0016] Preferably, both ends of the mounting frame are threadedly mounted with fastening bolts, and the fastening bolts limit the position of the circuit breaker and the overvoltage protector. The circuit breaker and the overvoltage protector are limited by the fastening bolts, so that after the personnel install the circuit breaker and the overvoltage protector in the mounting frame, they can rotate the fastening bolts for squeezing and limiting.

[0017] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0018] 1. The utility model sets a second mounting plate. When personnel adjust the air-separation electric heater, they can control it through the temperature controller, protection relay, frequency controller, thyristor, etc. on the mounting plate inside the power regulating cabinet body. At the same time, when the power regulating cabinet body is not working, there is voltage at the output end due to the breakdown of the thyristor. When the overvoltage protector is added and a three-phase or single-phase voltage signal is detected at the output end, the overvoltage protector trips the circuit breaker and cuts off the power supply, thereby forming an anti-dry burning component.

[0019] 2. The utility model sets a power adjustment cabinet body. When personnel use the power adjustment cabinet body to adjust the air separation electric heater, they can install and limit it by sliding the mounting plate one and the mounting plate two in the guide rail two and the guide rail one. After limiting, the personnel can open the driving mechanism to drive the screw rod to rotate. According to the rotation direction of the screw rod, the mounting plate one and the mounting plate two can be driven to move forward and backward through the guide frame, so that the mounting plate one and the mounting plate two can be driven to unfold from the power adjustment cabinet body, so as to meet the needs of later operation and maintenance, avoid the inconvenience caused by reaching in for maintenance, and open the air intake fan in the air intake pipe to perform air intake and heat dissipation in the power adjustment cabinet body, so as to meet the needs of later use.

Those skilled in the art can make any selections according to their needs or convenience.

[0034] A mounting base 4 is welded to the bottom end surface of the power control cabinet body 9, and a mounting block 1 is welded to the bottom end surface of the mounting base 4.
