[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0033] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0035] As attached Figure 1 , 2 , 4 and attached Figure 6 As shown:

[0036] Embodiment 1: This embodiment provides a mixing device for preparing fire clay and refractory premixed powder, comprising a frame 1, a feeding mechanism 2 and a mixer 3; the frame 1 comprises a plurality of support rods 101 arranged in a ring shape, a platform is arranged between the plurality of support rods 101, and a plurality of workstations are arranged between the support rods 101 and the platform; the feeding mechanism 2 comprises a storage hopper 201 arranged on the workstation, a weighing hopper 202 is arranged on the workstation at the bottom of the storage hopper 201, a discharge port 1 2018 is arranged at the bottom of the storage hopper 201, a feed port 2 2021 is arranged at the top of the weighing hopper 202, and a discharge port 2 2023 is arranged at the bottom of the weighing hopper 202; the discharge port 1 2018 is connected to the feed port 2021, and the discharge port 2 2023 is connected to the feed port of the mixer 3.

[0037] This design application is applied to the use scenario of mixing multiple powder materials. It is preferred to pre-mix the matrix powder material of the product with larger powder particles and pre-mix the fine powder material when preparing the refractory fire mud, so that the powder of the fire mud and the castable, i.e. the matrix part, is evenly mixed, making the product quality more stable.

[0038] During work, one worker stands on the platform, and another worker uses a crane hook to deliver the material bag to the platform under the platform. Then the worker on the platform adds the material in the material bag into the storage hopper 201 for storage. The storage hoppers 201 in several workstations are ring-shaped and surround the platform. Their discharge ports 2018 are directly connected to the feed port of the mixer 3 through the weighing bucket 202. Multiple powder materials can be added at different positions in different directions at the same time, so that multiple powder materials can enter the mixer 3 at different positions at the same time, evenly distribute the materials, and improve the mixing uniformity. Then, through the planetary mixer 3 with no dead angle below, the closed high-speed stirring can make the powder material mixing more uniform, the product performance more stable, and avoid dust and powder floating out to affect the working environment and cause differences in the powder ratio. At the same time, the workers on the platform only need to turn around slightly to switch workstations without walking back and forth, which minimizes the invalid movement space of the operators, reduces the physical consumption of employees, and improves labor production efficiency.

[0039] During the sub-packaging and mixing operation, the first discharge port 2018 is connected to the second feed port 2021, so that the material in the storage hopper 201 is input into the weighing hopper 202. During this process, the weighing hopper 202 will detect the weight of the material inside it to ensure the accuracy of the ingredients. Then, the second discharge port 2023 is connected to the feed port of the mixer 3, so that the material with the accurate weight in the weighing hopper 202 is introduced into the mixer 3. Then, the mixer 3 is started to pre-mix the fine powder part to make the fine powder more uniform. Then, the sub-packaging bag is placed at the outlet of the mixer 3, and the mixed material will be introduced into the sub-packaging bag through the outlet to complete the powder sub-packaging operation.

[0040] The storage hopper 201, the weighing hopper 202 and the mixer 3 are integrated to reduce the installation space of the equipment, which is beneficial to the centralized treatment of dust removal equipment and sanitation.

[0041] As attached Figure 1 , 2 , Attachment Figure 7 As shown:

[0042] Specifically, the frame 1 adopts an octagonal structure, and six workstations are arranged.

[0043] The frame 1 is connected and load-bearing by I-beams to ensure the safety of the frame 1.

[0044] As attached Figure 3 and attached Figure 4 As shown:

[0045] Specifically, a feed port 2016 is provided at the top of the storage hopper 201, guide rails 2012 are fixedly installed on the top of the storage hopper 201 on both sides of the feed port 2016, a cover plate 2014 is slidably installed between the guide rails 2012 on the top of the feed port 2016, an electric push rod 2013 is movably installed between the cover plate 2014 and the storage hopper 201, and a protective frame 2015 is fixedly installed on the top of the storage hopper 201 outside the cover plate 2014.

[0046] When the storage bin 201 needs to be refilled, the electric push rod 2013 is started, and the electric push rod 2013 will push the cover plate 2014 to slide on the guide rail 2012 so that it is staggered with the feed port 1 2016 to facilitate the personnel to carry out the refilling work, and the protection frame 2015 will protect the feed port 1 2016 and the cover plate 2014.

[0047] As attached Figure 4 As shown:

[0048] Specifically, a screw feeder 2017 is provided between the storage hopper 201 and the discharge port 2018, and a discharge gate 2019 is installed on the discharge port 2018.

[0049] When the staff needs to import materials from the storage hopper 201 into the weighing hopper 202, the screw feeder 2017 is started. The screw feeder 2017 is driven by a reduction motor and uses the feeding screw to send the material to the discharge port 2018, and then falls into the weighing hopper 202. When the weighing hopper 202 detects that the material content therein has reached the required content, the screw feeder 2017 is closed, and the discharge port 2018 is closed using the discharge gate 2019 to improve accuracy.

[0050] As attached Figure 5 and attached Figure 6 As shown:

[0051] Specifically, a pushing cylinder 2022 is provided at the rear end of the weighing bucket 202, and a discharge gate 2024 is installed on the second discharge port 2023.

[0052] When the staff needs to introduce materials from the weighing bucket 202 into the mixer 3, the pushing cylinder 2022 and the discharging gate 2024 are started, the discharging gate 2024 will open the discharge port 2023, and the pushing cylinder 2022 will push the materials in the weighing bucket 202 out of the discharge port 2023 to increase the loading speed. When the materials in the weighing bucket 202 are completely discharged, the discharge gate 2024 will be used to close the discharge port 2023 to facilitate the staff to carry out weighing work again.

[0053] As attached Figure 1 and attached Figure 2 As shown:

[0054] Specifically, a dust suction pipe 204 is arranged between several support rods 101, and a U-shaped tube 205 is arranged between the dust suction pipe 204 and the storage hopper 201. The dust suction pipe 204 is connected to all the storage hoppers 201 at the same time, and then connected to an external negative pressure dust suction device, so that the dust in all the storage hoppers 201 can be centrally processed at one time. The setting of the U-shaped tube 205 can prevent materials from entering the dust suction pipe 204.

[0055] Specifically, a connecting frame 104 is fixedly installed between the supporting frame 103 and the platform, and a control box 105 is arranged on the connecting frame 104 . The staff on the platform can control the device by using the control box 105 .

[0056] As attached Figure 1 , 2 , 3 and attached Figure 5 As shown:

[0057] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the workstation includes a fixing frame 102 arranged directly between adjacent support rods 101 and between the support rods 101 and the platform, and a supporting frame 103 is fixedly installed between adjacent support rods 101 at the top of the fixing frame 102.

[0058] Specifically, weighing wing plates 203 are fixedly installed on both sides of the weighing bucket 202, a weighing sensor 206 is arranged between the bottom of the weighing wing plate 203 and the fixed frame 102, a fixing plate 2011 is fixedly installed on the storage hopper 201 on the top of the support frame 103, and a lifting ring 207 is installed on the top of the fixing plate 2011 and the weighing bucket 202.

[0059] As can be seen from the above, when performing replacement and maintenance work on the storage hopper 201 and the weighing hopper 202, it is only necessary to use external lifting equipment to connect the lifting ring 207 to lift the storage hopper 201 and the weighing hopper 202 to separate them from the frame 1. During installation, the storage hopper 201 and the weighing hopper 202 are placed on the frame 1 from top to bottom. At this time, the weighing hopper 202 will be placed on the fixed frame 102 through the weighing wing plate 203, and the storage hopper 201 will be placed on the support frame 103 through the fixed plate 2011. After being reinforced with bolts, the discharge port 2018 of the storage hopper 201 will be connected to the weighing hopper 202 at its bottom. Replacement is quick and easy, and it is convenient for personnel to use.

[0060] Embodiment 3: This embodiment is basically the same as the previous embodiment, except that the fire clay and refractory premixed powder preparation and stirring device further includes an upper and lower detection module for providing an alarm when the material in the storage hopper 201 reaches the upper limit or the lower limit;

[0061] When the material in the storage hopper 201 reaches the lower limit, it indicates that the material is insufficient, and an alarm is issued to remind the staff to refill the material. When the material reaches the upper limit, it indicates that the material reaches the set value, and an alarm is issued to remind the staff to stop refilling to avoid overflow.

[0062] The weighing bucket 202 is provided with a weighing value, and is provided with a rough weighing section and a fine weighing section. In the rough weighing section, the screw feeder 2017 feeds materials quickly, and after reaching the set value, it switches to the fine weighing section, and the screw feeder 2017 discharges materials slowly, thereby improving the weighing efficiency and accuracy.
