Description

Technical Field

[0001] The utility model relates to the technical field of producing cement from waste residues, in particular to a filtering mechanism used for producing cement from waste residues. Background Art

[0002] Industrial waste slag can be recycled to produce cement, reducing carbon emissions and co-disposing of industrial waste and garbage. In the process of producing cement from waste slag, a filtering mechanism is required to filter the waste slag.

[0003] For example, a Chinese patent with publication number CN214077761U discloses a filtering mechanism for producing cement from waste slag, whose structure includes a discharge box, an auxiliary mechanism, a perspective window, a discharge port, a power cord, a fixed plate, a support leg, a filter bucket, a filter screen, a switch, a movable door and a handle. The utility model is provided with an auxiliary mechanism on the left side of the discharge box. The telescopic device arranged in the auxiliary mechanism facilitates the outer frame to be pressed against the bottom of the fixed plate, effectively preventing the waste slag on the filter screen from falling into the discharge box, and enhancing the work efficiency of cement production. A limiting device is arranged on the left side of the telescopic device, and the top plate and the inclined plate arranged in the limiting device can better speed up the discharge speed, and indirectly enhance the efficiency of cement production.

[0004] This patent can prevent impurities from entering the discharge box when cleaning impurities on the filter, thereby ensuring the filtering effect. However, this patent can only clean impurities when the waste residue filtering stops. In some cases, a large amount of waste residue needs to be filtered. Therefore, when a large amount of impurities accumulate on the top of the filter, it is necessary to stop the waste residue filtering operation, clean the impurities and then restart the waste residue filtering. The above steps may need to be performed multiple times in one waste residue filtering, thereby reducing the efficiency of filtering a large amount of waste residue. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a filtering mechanism for producing cement from waste residues, which has the effect of improving the filtering efficiency of a large amount of waste residues.

[0012] Through the above technical solution, automatically controlling the rotation angle of the motor facilitates the use of the operator.

When the spring is in a natural state, the corresponding filter plate is in a horizontal state and completely shields the corresponding filter port, and an adjusting part is arranged above the filter plate.

[0014] Through the above technical solution, through the cooperation of the vertical rod, the slider, the spring, the connecting rod and the adjusting part, the user can adjust the angle of the filter plate to make the filter plate rotate obliquely downward, so that the impurities on the top of the filter plate fall into the impurity cavity, improving the efficiency of impurity cleaning.

[0015] In a preferred example of the present utility model, it can be further configured that: the adjusting part includes a U-shaped plate, the two ends of the U-shaped plate are respectively fixedly connected to the corresponding two sliders, and when the spring is in a natural state, the U-shaped plate is completely located inside the corresponding filter port, and a screw rod is threadedly connected to the position of the housing upper half corresponding to the U-shaped plate, and the screw rod is located directly above the impurity cavity.

The impurities on the top of the filter plate will automatically fall into the impurity cavity under the action of gravity, and there is no need for the user to manually remove the impurities on the top of the filter plate, improving the efficiency of impurity cleaning and facilitating the use of the user.

Detailed Description of the Embodiment

[0024] The following further describes the present utility model in detail with reference to the accompanying drawings. Embodiment

[0025] Refer to Figures 1 to 3The utility model discloses a filtering mechanism for waste slag production of cement, comprising a shell 1, a rotating disk 2 is rotatably connected to the top wall of the shell 1, two filter ports 3 are provided on the top of the rotating disk 2, and a filter plate 4 is hinged on the inner wall of the filter port 3, and impurities in the waste slag cannot pass through the filter plate 4.

[0026] An adjustment mechanism 5 is provided above the filter plate 4. A feed hopper 6 is fixedly provided at a position corresponding to one of the filter ports 3 on the top of the housing 1. Waste residue enters the corresponding filter port 3 through the feed hopper 6 and falls to the top of the corresponding filter plate 4 for waste residue filtering.

[0027] The inner bottom wall of the shell 1 is fixedly connected with a partition 7, the top of the partition 7 is in contact with the bottom surface of the rotating disk 2, and the partition 7 divides the lower half of the shell 1 into a collecting chamber 8 and an impurity chamber 9. The collecting chamber 8 and the impurity chamber 9 are respectively located directly below the corresponding filter ports 3, and the collecting chamber 8 is located directly below the feed hopper 6. The waste residue filtered by the filter plate 4 falls into the collecting chamber 8.

[0028] A discharge pipe is fixedly provided at the bottom of the collecting chamber 8 and the impurity chamber 9. The discharge pipe is initially closed by a valve. When waste residue and impurities need to be removed, the valve is opened to discharge the waste residue or impurities from the shell 1 through the discharge pipe.

[0029] A driving part is provided below the housing 1. The driving part includes a support frame, which is fixedly connected to the bottom of the housing 1. A motor 10 is fixedly connected inside the support frame, and a driving rod 11 is transmission-connected to the output end of the motor 10. The driving rod 11 rotates through the bottom wall of the housing 1 and the partition 7, and the top end of the driving rod 11 is fixedly connected to the bottom of the rotating disk 2.

[0030] The motor 10 drives the driving rod 11 to rotate, the driving rod 11 drives the rotating disk 2 to rotate, and the rotating disk 2 drives the filter plate 4 to rotate. The motor 10 is electrically connected to the PLC controller, and the PLC controller controls the motor 10 to drive the rotating disk 2 to rotate 180 degrees each time it works. The two filter ports 3 are mirror-imaged about the center line of the rotating disk 2, so that the two filter plates 4 exchange positions each time the motor 10 rotates.

[0031] The adjustment mechanism 5 includes two fixed plates 51 fixedly connected to the inner wall of the filter port 3, a vertical rod 52 is fixedly connected to the top of the fixed plate 51, a slider 53 is slidably sleeved on the outer peripheral surface of the vertical rod 52, a spring 54 is fixedly connected between the slider 53 and the corresponding fixed plate 51, and the vertical rod 52 passes through the corresponding spring 54.

[0032] A connecting rod 55 is hinged on one side of the slider 53, and one end of the connecting rod 55 away from the corresponding slider 53 is hinged to the top of the corresponding filter plate 4. When the spring 54 is in a natural state, the corresponding filter plate 4 is in a horizontal state and completely covers the corresponding filter port 3 (such as Figure 2As shown, at this time, the waste residue cannot pass through the gap between the filter plate 4 and the filter opening 3, and can only pass through the filter plate 4 for filtration.

[0033] The filter plate 4 is made of soft material near the side wall, so that the filter plate 4 can be fully attached to the inner wall of the filter opening 3 and can rotate at the same time.

[0034] An adjusting part 56 is arranged above the filter plate 4. The adjusting part 56 includes a U-shaped plate 561, and both ends of the U-shaped plate 561 are fixedly connected to the corresponding two sliders 53 respectively. When the spring 54 is in the natural state, the U-shaped plate 561 is completely located in the corresponding filter opening 3 to prevent the U-shaped plate 561 from being squeezed when the rotating disk 2 rotates. A screw rod 562 is threadedly connected to the upper half of the housing 1 at the position corresponding to the U-shaped plate 561, and the screw rod 562 is directly above the impurity cavity 9.

[0035] Rotating the screw rod 562 drives the screw rod 562 to move downward. The screw rod 562 contacts the U-shaped plate 561 and pushes the U-shaped plate 561 to move downward. The U-shaped plate 561 drives the slider 53 to move, the slider 53 drives the connecting rod 55 to move, and the connecting rod 55 drives the filter plate 4 to rotate. A gap is generated between the filter plate 4 and the inner wall of the filter opening 3, and the filter plate 4 is inclined, so that the impurities at the top of the filter plate 4 fall into the impurity cavity 9 under the action of gravity.

[0036] The implementation principle of the above embodiment is as follows:

[0037] The waste residue enters the corresponding filter opening 3 through the feed hopper 6 and falls onto the top of the corresponding filter plate 4 for waste residue filtration. The filtered waste residue falls into the collection cavity 8.

[0038] When the impurities on the top of the filter plate 4 below the feed hopper 6 accumulate too much, start the motor 10 to work. The motor 10 drives the drive rod 11 to rotate, the drive rod 11 drives the rotating disk 2 to rotate, and the rotating disk 2 drives the filter plate 4 to rotate 180°, so that the two filter plates 4 exchange positions. At this time, the new filter plate 4 continues to filter the waste residue. Rotate the screw rod 562 to drive the screw rod 562 to move downward. The screw rod 562 contacts the U-shaped plate 561 and pushes the U-shaped plate 561 to move downward. The U-shaped plate 561 drives the slider 53 to move, the slider 53 drives the connecting rod 55 to move, and the connecting rod 55 drives the filter plate 4 to rotate. A gap is generated between the filter plate 4 and the inner wall of the filter opening 3, and the filter plate 4 is inclined, so that the impurities accumulated on the top of the filter plate 4 fall into the impurity cavity 9 under the action of gravity.

[0039] After the impurities completely fall into the impurity cavity 9, rotate the screw rod 562 in the reverse direction. The screw rod 562 rises, and the slider 53 returns to its original position under the restoring force of the spring 54, so that the filter plate 4 returns to the horizontal state until the filter plate 4 below the feed hopper 6 also accumulates too many impurities, and then start the motor 10 again to repeat the above steps.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
