Description

Technical Field

[0001] The utility model belongs to the field of filter press conveyor belt devices, in particular to an automatic regulating and limiting device for a filter press conveyor belt. Background Art

[0002] The mine currently uses 14 diaphragm filter presses, which are mainly used to dry and dehydrate mine tailings and sulfur products. The dehydrated materials are transported to the designated location by a conveyor belt just below the filter press discharge port.

[0003] Belt conveyors are used to transport powdery and granular materials. They have a long, frame-shaped frame with smooth cylindrical rollers mounted on the front and rear ends. Idlers are evenly distributed along the frame's length. These rollers can be straight or grooved. An endless conveyor belt is connected between the rollers at the front and rear ends. The inner surface of the endless conveyor belt is flat. Due to component machining and installation accuracy, as well as maintenance requirements, belt conveyors are prone to belt deviation during operation. To prevent this, conventional belt conveyors have left and right runners at the front and rear ends, each equipped with a bearing seat. The roller shaft is mounted on the bearing seat on the runner. An adjustment rod is connected between the bearing seat and the frame. If the belt deviates, the operator must adjust the length of the adjustment rod to correct the deviation. This type of anti-deviation belt conveyor is very troublesome to adjust when the conveyor belt deviates. It is not only labor-intensive, time-consuming and labor-intensive, but also unable to correct the deviated conveyor belt in a timely manner, often leading to wear and damage of the conveyor belt, spillage of materials, and a huge waste of costs.

[0004] Secondly, during the operation of the filter press, the filtrate or leaked liquid material is often discharged into the conveyor belt below the filter press due to damage to the filter plate or filter cloth, or limited capacity of the filter press drainage trough. The filtrate or leaked liquid material flows through the conveyor belt cylinder and is discharged in a scattered manner, causing the tail wheel to slip frequently, resulting in hidden dangers of equipment accidents, polluting the on-site environment, leading to environmental pollution accidents, and corroding equipment.

[0028] The support seats 6 are symmetrically distributed on both sides of the conveyor belt to provide support for the limiting wheel device 4 and the parallel roller device 5. The triangular scraper 7 is installed in front of the parallel roller device 5 to clean the surface of the conveyor belt and prevent foreign matter from entering between the parallel roller devices 5 and damaging the parallel roller devices 5. The collection tank 8 is installed under the tail wheel device 1 to collect the filtrate and materials leaked from the filter press and guide them to the discharge point to prevent messy discharge from causing the tail wheel to slip and pollute the equipment and the on-site environment. The screw rod 9 is used to connect the limiting wheel device 4 to the support seat 6, and it is convenient to adjust the position of the limiting wheel device 4 according to process requirements. The flanged dust cover 10 is a telescopic structure installed on both sides of the screw rod. The flange is locked to the wheel device 4 and the support seat 6 to protect the screw rod 9 and prevent corrosion from affecting the adjustment function of the screw rod 9.

[0029] Among them, Figure 1-7 As shown, the conveyor belt 2 and the first wheel 3 are conventional conveyor belt devices.

[0030] Among them, Figure 1-7 As shown, the tail wheel device 1 includes a support frame 1-1, an adjusting bolt sleeve 1-2, a tapered sleeve 1-3, a square head bolt sleeve 1-4 and a tail wheel 1-5. The support frame 1-1 is sleeved on the axis of the tail wheel 1-5 and is fixedly and symmetrically connected. The tapered sleeve 1-3 is set on the support frame 1-1 through the adjusting bolt sleeve 1-2. The tapered sleeve 1-3 is connected to the tail wheel 1-5 through the square head bolt sleeve 1-4. The conveyor belt 2 is sleeved on the tail wheel 1-5 and contacts the tapered sleeve 1-3.

[0031] The support frame 1-1 is set on the axis of the tail wheel 1-5 and is fixed and symmetrically connected to provide supporting force; the adjusting bolt sleeve 1-2 is used to adjust the positioning position of the cone sleeve to achieve the purpose of controlling the position of the conveyor belt, which is convenient for meeting the requirements of installing conveyor belts of different widths and adjusting the landing point of materials, and is conducive to the stability of conveying operation; the cone sleeve 1-3 is a symmetrical 4-sided incomplete concentric arc structure, which can be closely matched with the tail wheel 1-5 and has a sliding function. There is a threaded hole above the side ear wing for connecting the adjusting bolt sleeve 1-2, and a limiting groove below for installing the square head bolt sleeve 1-4, which is locked to the tail wheel 1-5. The cone sleeve 1-3 can make the conveyor belt recessed at the tail wheel. First, the conveyor belt can be positioned to prevent large-scale deviation, and the conveyor belt can automatically adjust the deviation according to the different landing points of the received materials. The procedure of the automatic adjustment function is that when the conveyor belt receives materials eccentrically, the conveyor belt running trajectory deviates to the direction of smaller force, but the tail wheel is conical, and the conveyor belt quickly reaches force balance and continues to maintain stable operation. When the landing point of the received material is normal, the force in the original eccentric direction becomes larger, and the conveyor belt automatically returns to the initial force balance position. Second, it can facilitate the collection of filtrate and slurry leaked from the filter press to the conveyor belt to prevent disorderly discharge; the tail wheel 1-5 is a commonly used cylindrical tail wheel, and a slide groove is processed on the side for installing the tapered sleeve 1-3.

[0032] Among them, Figure 1-7 As shown, the limiting wheel device 4 includes a limiting wheel 4 - 1 and a limiting wheel base 4 - 2 , the limiting wheel 4 - 1 is arranged on the limiting wheel base 4 - 2 , and the limiting wheel base 4 - 2 is arranged on two screw rods 9 .

[0033] The shaft head is square for easy locking and fixing, and has the ability to withstand large radial loads. It can limit the running track of the conveyor belt to prevent large-scale left and right deviations and upward tilting. The limiting wheel base 4-2 is used to install and fix the limiting wheel 4-1. The connection with the limiting wheel 4-1 is an outer circle inner square block structure.

[0034] Among them, Figure 1-7 As shown, the limiting wheel 4-1 is an I-shaped heavy-duty wheel.

[0035] Among them, Figure 1-7 As shown, the parallel roller devices 5 are symmetrically distributed on both sides of the limiting wheel device 4.

[0036] The parallel roller device 5 is symmetrically distributed on both sides of the limiting wheel device 4 to support the conveyor belt and compress the deformation space of the conveyor belt to keep the conveyor belt flat, better ensure the limiting of the conveyor belt by the limiting wheel device 4 and reduce the influence range of the tail wheel cone surface on the conveyor belt.
