BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a burner sensing device that has been electrolytically removed from titanium anodes.

Burel is produced from an aqueous solution of manganese sulphate and sulfuric acid by electrolytic deposition on titanium anodes.

Excluded solids adhere to titanium electrodes. On one titanium electrode with dimensions of 1 000 x 800 mm, a 90 kg burle is eliminated in one cycle. Reducing the amount of burner from each titanium electrode by hand shaking is strenuous and time consuming. Also, the solution according to British Patent No. 423,503, according to which each anode is deflected from a vertical position and released to the bumper, is not a perfect solution from the point of view of removing the bullet, it is noisy and cannot be automated. A device has also been developed in which the anodes, individually or in bundle, pass through a cylinder system where the deformation is eliminated and the burel is dropped due to the stress difference. However, this device did not test during the tests, since the removal of the burner was incomplete. The solution to the problem is a device for sensing the manganese dioxide bile excreted on the titanium electrodes according to the invention, which consists in folding out a rectangular horizontal fixed frame in which the guide rods and the free cross-section are fastened by 8 contact pitches. Between the individual guide rods larger than the thickness of the titanium electrode, including the excluded bullet, under the rigid frame, a free-swinging frame is mounted under the rigid frame on which support rods, which are coaxial with the guide rods, are fixed over vertical leaf springs. they are provided with point-pointing in the horizontal direction into the space between the support rods, the smallest spacing between the tips being greater than the thickness of the titanium electrode including the burle.

Tests of the burner sensing on a cylinder system as well as tests on a high-frequency vibration device have shown that the elastic deformation of the anode plate itself is not sufficient to separate the burner from the anode. In these methods, only 30 to 60% of the product fell off. The solution according to the invention makes use of the knowledge that the burner layer destroyed by the heat sink falls almost completely. The main active element is the pointed impact and the elastic deformation is only an auxiliary - subsequent element. The basis of the device according to the invention is a system of two frames mounted horizontally in two parallel planes. The upper frame is rigid and is part of the supporting steel structure. Bars that serve to guide titanium electrodes are fixedly fixed in this rigid frame transversely, with a constant pitch. On the free arms, a movable (pivotable) frame is suspended under the upper frame, on which support rods with attached spikes are attached to the leaf springs in parallel and with the guide rods of the upper fixed frame. The oscillating (oscillating) movement of the lower swing frame is provided, for example, by an electric motor with a crank mechanism. A burner-attached titanium electrode block runs between the frame guide rods. When the lower edge of the titanium electrodes reaches the tip level, the movable frame is brought into a oscillating motion in a direction perpendicular to the surface of the titanium electrodes. The tips attached to the support rods impact on the surface of the burner layer and break the surface. Due to the shocks and possible elastic deformation of the titanium electrodes, the disrupted layer of the burel separates from the titanium electrode plate and falls into the product well.

The individual spikes may be pyramid-shaped, cone-shaped, or wedge-shaped, and should be made of a class 19 tool steel. Their number on one support rod is not prescribed. The intersection of the spikes on two adjacent support rods may not be opposed. The pace of the pendulum swing must be such that the prongs in the extreme positions do not strike the stripped titanium electrode, thus avoiding damage to the pile. The leaf springs on which the spike support rods are mounted should be

Figure 2 shows a schematic representation of the entire titanium electrode burner sensing device, and Figure 2 shows the location of the tines on the support rods. In the following, the device is described together with an explanation of its function. A fixed J-frame with guide rods 2 is mounted in the supporting structure. A swinging frame 4 is mounted on the fixed frame χ using free arms J. Support rods 8 are attached to the swing frame 4. -from each row of spikes 2 ·. The burner-adhering titanium electrode block 8 is lowered between the rigid frame guide rods 1. The oscillating frame 4 is driven by a drive into a oscillating motion in a direction perpendicular to the surface of the titanium electrodes. The studs mounted on the support rods 2, which are mounted on the leaf springs 6, strike the surface of the burner layer and break it up. As a result of the shocks and possible elastic deformation of the titanium electrode 8, the broken product layer is separated from the titanium electrode 8 and falls into the product well. The bonding of titanium electrodes 8 to solid blocks resulted from the requirement to shorten the nanipulation time when charging and balancing titanium electrodes 8 from the cells. This is why a metal supporting skeleton has been designed in which 7 pairs of titanium electrodes 8 with a thickness of 3-4 mm and SCO dimensions of up to 500 mm are fastened (suspended) by a screw connection. The deposited burner layer is 10 to 15 mm on each side of the titanium electrode 3. The weight of the titanium electrode block 8 with the expelled burel is about 700 kg.
