Abstract

The utility model relates to the technical field of waste residue brickmaking stirrers, and particularly discloses a steelmaking waste residue brickmaking stirrer which is characterized in that when more and more waste residues exist in a discharge hopper, the discharge hopper slides downwards along a support frame to compress a spring when the weight of the discharge hopper is increased, and when the two ends of the discharge hopper slide into a discharge frame, the discharge hopper cannot slide downwards due to the fact that one side of the discharge hopper is heavier. Therefore, the discharging hopper can overcome the pulling force of the tension spring to drive the discharging frame to rotate, waste residues in the discharging hopper can be poured into the stirring barrel after the discharging hopper rotates, the discharging frame resets under the pulling force of the tension spring after the weight of the discharging hopper is reduced, and after the discharging frame resets, the discharging hopper loses constraint and resets under the elastic force effect of the spring. After the discharge hopper is reset, the light activated switch can receive light emitted by the laser emitter, waste residues and cement are fed into the stirring barrel in batches according to a fixed proportion to be stirred, feeding and stirring are carried out at the same time, and the effect that the waste residues and the cement are accurately and fully mixed according to the proportion is achieved.

Description

Technical Field

[0001] The utility model relates to the technical field of waste slag brick-making mixers, in particular to a mixer for steelmaking waste slag brick-making. Background Art

[0002] Making bricks from steelmaking waste slag is an important way to utilize industrial waste slag generated during the steelmaking process as a resource. It not only helps to reduce environmental pollution, but also achieves economic benefits and resource conservation. In the process of making bricks from steelmaking waste slag, the main raw materials such as steel slag tailings and cement must first be mixed in proportion, evenly mixed, and moderately moistened with water.

[0003] When stirring in a mixer, due to the high density of steelmaking waste slag, if a large amount of waste slag is put in at one time, the mixer will find it difficult to fully mix the waste slag with other materials. Utility Model Content

[0004] (1) Technical problems solved

[0005] In view of the shortcomings of the existing technology, the utility model provides a mixer for making bricks with steelmaking waste slag, which solves the technical problem that due to the high density of steelmaking waste slag, a large amount of waste slag can be put into the mixer at one time, making it difficult to fully mix the waste slag with other materials.

[0006] (2) Technical solution

[0007] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A mixer for making bricks from steelmaking waste slag, comprising a support frame, a mixing barrel fixedly mounted on the bottom end of the support frame, two laser emitters symmetrically fixedly mounted on the support frame, two photosensitive switches symmetrically fixedly mounted on the support frame, two unloading mechanisms fixedly mounted on the top end of the support frame, the unloading mechanisms comprising two unloading frames, a unloading hopper, two springs, a pull rod and multiple tension springs, the two laser emitters and the photosensitive switches corresponding to the two unloading mechanisms respectively, the unloading hopper being slidably mounted on the support frame, the two unloading frames being symmetrically rotationally mounted on both sides of the support frame, the spring being mounted between the unloading frame and the unloading hopper, the pull rod being fixedly mounted between the two unloading frames, the tension spring being mounted between the mixing barrel and the pull rod, a stirring rod being rotationally mounted inside the mixing barrel, and a transmission gear set being fixedly mounted on the top end of the stirring rod.

[0009] Preferably, a motor is fixedly mounted on the top of the support frame; the motor drives the stirring rod to rotate through a transmission gear set.

[0010] Preferably, a counterweight is installed at the bottom end of the discharge hopper.

[0011] (3) Beneficial effects

[0012] 1. When the stirring rod is stirring, the discharge hopper is reset and reloaded. During the loading process of the discharge hopper, the stirring rod can fully mix the waste slag and cement entering the mixing barrel. The waste slag and cement are fed into the mixing barrel in batches according to a fixed ratio for stirring. The waste slag and cement are mixed accurately and fully according to the proportion while feeding and stirring.

[0013] 2. When the mixing ratio needs to be changed, the counterweight block at the bottom of the discharge hopper can be replaced with a counterweight block of different mass. When a counterweight block with a larger mass is replaced, the pressure of the discharge hopper on the spring increases, and the mass of the material that the discharge hopper can load is correspondingly reduced. When a counterweight block with a smaller mass is replaced, the pressure of the discharge hopper on the spring decreases, and the mass of the material that the discharge hopper can load is correspondingly increased, thereby achieving the effect of facilitating the regulation of the mixing ratio.

[0020] The embodiment of the present application provides a mixer for making bricks from steelmaking waste slag, which effectively solves the technical problem that due to the large density of steelmaking waste slag, a large amount of waste slag can be added at one time, making it difficult for the mixer to fully mix the waste slag and other materials. When the stirring rod is stirring, the discharge hopper is reset and reloaded. During the loading process of the discharge hopper, the stirring rod can fully mix the waste slag and cement entering the mixing barrel. The waste slag and cement are fed into the mixing barrel in batches according to a fixed ratio for stirring. The feeding and stirring are performed simultaneously, so that the waste slag and cement are accurately and fully mixed in proportion. When the mixing ratio needs to be changed, the counterweight block at the bottom of the discharge hopper can be replaced with a counterweight block of different mass. When a counterweight block with a larger mass is replaced, the pressure of the discharge hopper on the spring increases, and the mass of the material that the discharge hopper can load is correspondingly reduced. When a counterweight block with a smaller mass is replaced, the pressure of the discharge hopper on the spring decreases, and the mass of the material that the discharge hopper can load is correspondingly increased, thereby achieving the effect of facilitating the regulation of the mixing ratio.

[0021] Example

[0022] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that due to the high density of steelmaking waste slag, a large amount of waste slag is put into the mixer at one time, and it is difficult to fully mix the waste slag with other materials. The overall idea is as follows:

[0023] In response to the problems existing in the prior art, the utility model provides a mixer for making bricks from steelmaking waste slag, including a support frame 1, a mixing barrel 9 fixedly installed at the bottom end of the support frame 1, two laser emitters 7 symmetrically fixedly installed on the support frame 1, two photosensitive switches 8 symmetrically fixedly installed on the support frame 1, and two unloading mechanisms fixedly installed on the top end of the support frame 1. The unloading mechanism includes two unloading frames 2, a unloading hopper 3, two springs 4, a pull rod 5 and multiple tension springs 6.

[0024] The two laser emitters 7 and the photosensitive switch 8 correspond to the two unloading mechanisms respectively. The unloading hopper 3 is slidably installed on the support frame 1. The two unloading frames 2 are symmetrically rotated and installed on both sides of the support frame 1. The spring 4 is installed between the unloading frame 2 and the unloading hopper 3. The pull rod 5 is fixedly installed between the two unloading frames 2.

[0025] The tension spring 6 is installed between the mixing barrel 9 and the pull rod 5. A stirring rod 11 is rotatably installed inside the mixing barrel 9. A transmission gear set 13 is fixedly installed on the top of the stirring rod 11. A motor 12 is fixedly installed on the top of the support frame 1; the motor 12 drives the stirring rod 11 to rotate through the transmission gear set 13, and a counterweight block 14 is installed at the bottom end of the discharge hopper 3.

[0026] Working principle:

[0027] The first step is to connect the two photosensitive switches 8 to the start and stop switches of the waste slag and cement feeding devices respectively, and install the discharge ports of the waste slag and cement feeding devices on the top of the two discharge hoppers 3 respectively. When in use, the motor 12 starts and drives the stirring rod 11 to rotate through the transmission gear set 13, and the waste slag and cement are respectively fed into the two discharge hoppers 3 by the feeding device. When the waste slag inside the discharge hopper 3 becomes more and more, the weight of the discharge hopper 3 increases and slides downward along the support frame 1 to compress the spring 4. When the two ends of the discharge hopper 3 slide into the discharge frame 2, the light emitted by the laser emitter 7 to the photosensitive switch 8 will be blocked, causing the feeding device to stop feeding. Since the weight of one side of the discharge hopper 3 is larger, the discharge hopper 3 will overcome the tension of the tension spring 6. As the discharge frame 2 rotates, the discharge hopper 3 rotates and the waste residue inside can be poured into the mixing barrel 9. When the waste residue inside the discharge hopper 3 is poured out, the weight of the discharge hopper 3 is reduced and the discharge frame 2 will be reset under the tension of the tension spring 6. When the discharge frame 2 is reset, the discharge hopper 3 loses its constraint and will be reset under the elastic force of the spring 4. After the discharge hopper 3 is reset, the photosensitive switch 8 can receive the light emitted by the laser emitter 7, so that the feeding device continues to feed into the discharge hopper 3. At the same time, the waste residue and cement that fall into the support frame 1 will be stirred under the action of the rotation of the stirring rod 11, and the waste residue and cement will be fed into the mixing barrel 9 in batches according to a fixed ratio for stirring. The waste residue and cement are fed and stirred at the same time, so as to achieve the effect of accurately and fully mixing the waste residue and cement in proportion.

[0028] In the second step, the tension spring 6 and the counterweight 14 are connected by a hook. When the mixing ratio needs to be changed, the counterweight 14 at the bottom of the discharge hopper 3 can be replaced with a counterweight 14 of different mass. When the counterweight 14 with a larger mass is replaced, the pressure of the discharge hopper 3 on the spring 4 increases, and the mass of the material that the discharge hopper 3 can load is reduced accordingly. When the counterweight 14 with a smaller mass is replaced, the pressure of the discharge hopper 3 on the spring 4 is reduced, and the mass of the material that the discharge hopper 3 can load is increased accordingly. At the same time, when replacing the counterweight 14 with a larger mass, the number of tension springs 6 needs to be increased to improve the ability of the discharge frame 2 to reset. When replacing the counterweight 14 with a smaller mass, the number of tension springs 6 needs to be reduced to reduce the ability of the discharge frame 2 to reset, thereby achieving the effect of facilitating the regulation of the mixing ratio.

Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
