Description

Technical Field

[0001] The utility model relates to the technical field of aluminum electrolysis, in particular to a tool for measuring the total current of an anode and the temperature of a square steel for aluminum electrolysis. Background Technique

[0002] The anode current and the temperature of the square steel are key parameters for evaluating the operation status of the electrolytic cell, which are directly related to the efficiency and energy consumption of the electrolysis process. By monitoring the anode current distribution, the uneven current problem in the electrolytic cell can be detected and adjusted in time to ensure the uniformity and stability of the electrolysis process, thereby optimizing the entire electrolysis process.

[0003] Currently, when manually detecting the anode current, usually according to the anode position to be measured, the measuring fork or probe is placed at the corresponding position, the power is turned on, and the value of the anode current is recorded after waiting for the reading to stabilize. However, this operation method is restricted by the site and is not convenient for personnel to operate. At the same time, when the temperature of the square steel needs to be measured, the temperature measuring equipment needs to be reinstalled.

[0004] Therefore, in view of the above problems, a tool for measuring the total current of an anode and the temperature of a square steel for aluminum electrolysis is proposed to solve the above problems. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model develops a tool for measuring the total current of an anode and the temperature of a square steel for aluminum electrolysis. The utility model can measure the anode current of aluminum electrolysis and can also measure the temperature of the square steel.

[0006] The technical solution for the utility model to solve the technical problem is: a tool for measuring the total current of an anode and the temperature of a square steel for aluminum electrolysis, including a telescopic rod. The telescopic rod includes a grip, and a clamping head is arranged at one end of the telescopic rod away from the grip. A current detection device and a temperature detection device are arranged at the grip.

[0007] By setting the telescopic rod to control the distance between the clamping head and the grip, it is suitable for clamping and measuring the current of the anode conductive rod of aluminum electrolysis in different scenarios, which is convenient for the detection personnel to operate and avoids the inconvenience of the detection personnel to clamp the anode conductive rod due to inappropriate positions. The current detection device selects the full current meter model 42L6 - A COS / HZ, and the temperature detection device selects the infrared thermometer OPTCTL3ML model. The full current meter detects the current of the anode conductive rod of aluminum electrolysis, and the infrared thermometer detects the temperature of the cathode square steel.

[0008] Preferably, the clamping head includes a support plate, a baffle plate, a guide hole, a guide rod, a retaining ring and a clamping plate. The support plate is arranged at one end away from the grip of the telescopic rod. Baffle plates are symmetrically arranged on the side of the support plate away from the telescopic rod. Guide holes are provided in the baffle plates. Guide rods are slidably connected in the guide holes. A retaining ring is arranged at one end of the guide rod outside the two baffle plates. A clamping plate is arranged at one end of the guide rod between the two baffle plates. The clamping plate is slidably connected to the support plate.

[0009] The aluminum electrolysis anode conductive rod is clamped by the symmetrically arranged clamping plates. At the same time, during the clamping process, the contact conducts the current of the anode conductive rod to the current detection device to detect the current.

[0010] Preferably, the clamping head further includes a compression spring, a contact and an inclined plate. The compression spring is sleeved on the guide rod. One end of the compression spring is connected to the baffle plate, and the other end of the compression spring is connected to the clamping plate. A contact is arranged on the side of the clamping plate away from the guide rod. The contact is electrically connected to the current detection device. An inclined plate is arranged at one end of the clamping plate away from the grip. The inclination direction of the inclined plate inclines outward from the axis of the grip.

[0011] Through the symmetrically arranged inclined plates, when the clamping head extends towards the anode conductive rod, the two inclined plates are pushed apart to enable the anode conductive rod to enter between the two clamping plates. Under the action of the compression spring, the symmetrically arranged clamping plates squeeze the anode conductive rod to achieve firm clamping.

[0012] Preferably, the telescopic rod includes an extension rod, a sliding groove, a limiting groove and a limiting block. A sliding groove is arranged in the grip. The extension rod is slidably connected in the sliding groove. Limiting grooves are symmetrically arranged on the inner wall of the sliding groove. Limiting blocks are symmetrically arranged at one end of the extension rod located in the sliding groove. The limiting blocks are slidably connected in the limiting grooves. A support plate is arranged at one end of the extension rod away from the limiting groove.

[0013] The extension rod is slidably connected in the sliding groove of the grip, and the distance of the clamping head is adjusted by telescoping in the sliding groove. Through the cooperation between the sliding block and the limiting groove, the rotation of the extension rod and the clamping head is prevented.

[0014] Preferably, the telescopic rod further includes a knob, a threaded rod, a threaded hole, a clamping groove and a limiting ring. A threaded hole is arranged in the extension rod. The threaded rod is threadedly connected in the threaded hole. A knob is arranged at one end of the threaded rod away from the support plate. The knob is rotatably connected to the grip. A limiting ring is arranged at a position of the threaded rod close to the knob. The limiting ring is rotatably slidably connected in the clamping groove.

[0015] By rotating the knob, the knob drives the threaded rod to rotate. The threaded rod and the threaded hole cooperate to push the extension rod to move, and self-locking can be formed between the threaded rod and the threaded hole, making the extension rod relatively stable during use. By arranging the limiting ring and the clamping groove, the separation of the knob and the threaded rod is prevented.

[0016] Preferably, a plurality of support rods are provided on the grip, mounting plates are provided on the support rods, current detection devices and temperature detection devices are provided on the mounting plates, and suspension straps are provided on the support plates.

[0017] By providing the support rods and the mounting plates, it is convenient to install the current detection devices and the temperature detection devices, and by providing the suspension straps on the support plates, it is convenient for the operator to carry.

[0018] The effects provided in the utility model content are only the effects of the embodiments, rather than all the effects of the utility model. The above technical solutions have the following advantages or beneficial effects:

[0019] By providing a telescopic rod to control the distance between the clamping head and the grip, it is applicable to clamp and measure the current of the aluminum electrolysis anode conductive rod in different scenarios, which is convenient for the detection personnel to operate and avoids the detection personnel being inconvenient to clamp the anode conductive rod due to inappropriate positions.

[0020] Through the symmetrically arranged inclined plates, when the clamping head extends towards the anode conductive rod, the two inclined plates are pushed apart to both sides, so that the anode conductive rod enters between the two clamping plates, and under the action of the compression spring, the symmetrically arranged clamping plates squeeze the anode conductive rod to achieve firm clamping.
