Description

Technical Field

[0001] This utility model relates to the field of thickener measurement technology, specifically a peripheral drive thickener measurement platform. Background Technology

[0002] A thickener is a solid-liquid separation device based on gravity settling. The slurry enters the thickening tank through the central feed pipe. The solid particles gradually settle under gravity, forming a clear water layer on top, which is discharged through the overflow trough. The rake frame rotates around the tank body under the drive of the transmission device, scraping the settled sludge to the discharge port at the bottom of the tank, and finally discharged in the form of high-concentration underflow.

[0003] During the mineral processing, due to the reagents, a foam layer forms on the surface of the thickener in the peripheral drive thickener. To prevent metal loss, a baffle is installed at the front of the overflow weir to prevent metal loss from the foam layer, allowing the clarified return water to flow into the overflow weir. During production, personnel need to determine the depth of the ore layer in the thickener by stepping onto the overflow weir foundation. The overflow weir foundation is narrow, posing a significant risk to the measurement personnel. Conventionally, the measurement platform is placed on the peripheral drive thickener. Given the above, the measurement platform must not interfere with the operation of the traveling rake frame of the peripheral drive thickener to reduce safety risks. Utility Model Content

[0004] The purpose of this invention is to provide a peripheral drive thiocyanate measuring platform to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A peripheral drive thickener measuring platform includes a baffle, an angle iron frame, and a grid screen plate laid within the angle iron frame. The rear end of the angle iron frame is attached to the concrete foundation of the thickener track, and its front end is supported by a horizontal adjustment unit on the concrete retaining wall at the front end of the overflow weir.

[0006] One side of the baffle is provided with slurry from the thickening tank, and a rack is provided on the top of the track concrete foundation.

[0007] The horizontal adjustment unit is used to compensate for the height difference between the track concrete foundation and the concrete retaining wall at the front end of the overflow weir, and to keep the angle iron frame horizontal.

[0008] The overall thickness of the angle iron frame is lower than the height of the rail on the track concrete foundation.

[0009] The horizontal adjustment unit includes multiple angle iron legs that are vertically welded to the bottom front end of the angle iron frame.

[0010] The number of angle iron legs is four, and each pair of angle iron legs forms a group, with the two groups connected by a horizontal steel pipe; the length of the steel pipe is greater than the thickness of the concrete retaining wall at the front end of the overflow weir, so that the front end of the angle iron frame is supported on the concrete retaining wall at the front end of the overflow weir through the steel pipe.

[0011] The length of the angle iron support leg is 10-20 cm longer than the height difference between the track concrete foundation and the front concrete retaining wall of the overflow weir.

[0012] The angle iron frame is also equipped with attachment points for securing safety belts.

[0013] Compared with the prior art, this utility model provides a peripheral drive thickener measurement platform, which has the following advantages: 1. This utility model utilizes the existing concrete foundation of the thickener track and the overflow weir retaining wall as support points to build a measurement platform, providing operators with a solid and stable working surface. This avoids the situation where personnel stand directly on the narrow overflow weir foundation to carry out high-risk measurements, thus improving operational safety and effectively preventing the risk of falls. 2. This utility model compensates for the inherent height difference between the track foundation and the retaining wall by setting up a horizontal adjustment unit composed of angle iron legs and steel pipes, thus ensuring the overall level of the measuring platform. At the same time, the design of the front end using steel pipes spanning across the retaining wall increases the contact area and friction, effectively preventing the platform from sliding forward or backward or overturning laterally during use. Its stability is significantly better than that of a simply stacked platform. 3. The overall thickness of the angle iron frame of this utility model is lower than the height of the thickener rail, which ensures that the platform is completely outside the operating space of the thickener traveling bridge after installation, thus avoiding interference or collision with moving parts such as the bridge and rake frame, ensuring the normal operation of the thickener and the safety of the platform itself. 4. The structure of this utility model is entirely welded from standard profiles such as angle steel, steel pipe, and sieve plate. The structure is simple and sturdy, with low manufacturing cost. It does not require any permanent modification or damage to the original structure of the thickener. It is easy to install and disassemble, and is an economical, efficient, practical, and safe improvement solution. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides the following technical solution: Combination Figures 1 to 2 A peripheral drive thickener measuring platform includes a baffle 2, an angle iron frame 8, and a grid screen 7 laid inside the angle iron frame 8. The rear end of the angle iron frame 8 is attached to the concrete foundation 4 of the thickener track, and its front end is supported by a horizontal adjustment unit on the concrete retaining wall 3 at the front end of the overflow weir.

[0018] A thickener pool 1 is provided on one side of the baffle 2, and a rack 6 is provided on the top of the track concrete foundation 4. It is built on the existing track concrete foundation 4 of the surrounding transmission thickener and the concrete retaining wall 3 at the front end of the overflow weir.

[0019] The measuring platform mainly consists of an angle iron frame 8, a grid sieve plate 7, and horizontal adjustable legs. First, a rectangular angle iron frame 8 is welded using angle steel. The overall height of this frame must be less than the height of the steel rail 5 installed on the concrete foundation 4 of the track, so as to ensure that the traveling bridge of the thickener can pass through without obstruction and will not collide with the measuring platform.

[0020] The rear end of the angle iron frame 8 is directly attached to the concrete foundation 4 of the track and is located in the front end area of ​​the rail 5. Its front end is supported by horizontal adjustable legs on the concrete retaining wall 3 at the front end of the overflow weir, which is of lower height.

[0021] The specific implementation method of the horizontal adjustment legs is as follows: On the left and right sides of the bottom front end of the angle iron frame 8, two vertically downward angle iron legs 10 are preferably welded (a total of four legs). The length of the angle iron legs 10 should be 10-20 cm longer than the actual height difference between the track concrete foundation 4 and the concrete retaining wall 3 at the front end of the overflow weir, so as to reserve space for the leveling operation.

[0022] To further enhance the stability and anti-slip capability of the platform's front end, the angle iron legs 10 on both sides are grouped into pairs, and a steel pipe 9 is horizontally welded between the two angle iron legs 10 in the same group, near their bottom ends. The length of the steel pipe 9 should be slightly greater than the thickness of the concrete retaining wall 3 at the front end of the overflow weir, so that when the platform is installed, the steel pipe 9 can span across the wall, thereby greatly increasing the contact area and friction, and effectively preventing the entire platform from moving back and forth.

[0023] After adjusting the welding position or length of the angle iron legs 10 to ensure that the angle iron frame 8 remains absolutely level at the front and rear support points, all components are firmly welded into shape.

[0024] Finally, the grid sieve plate 7 is laid and fixed in the inner frame of the angle iron frame 8 to form a non-slip working surface. In addition, to ensure safety, round steel can be welded or holes can be set at appropriate positions in the angle iron frame 8 as attachment points for safety belts.

[0025] When production personnel measure the depth of the thickener layer, the operator attaches a safety belt to the platform's anchor point and then stands on the stable screen plate 7 to perform the measurement work. This eliminates the need to risk walking across the narrow overflow weir foundation, greatly reducing safety risks. This invention has a simple structure, low cost, requires no modification to the original thickener structure, is easy to install and disassemble, and is highly practical.
