Description

Technical Field

[0001] This utility model relates to the field of casting technology, and more specifically, to an automatic weighing and adding device for inoculants. Background Technology

[0002] Inoculants are functional alloying materials added to molten metal during the casting process. They are mainly used to promote nucleation and refine grain structure, thereby improving the performance of castings.

[0003] Patent CN215697816U discloses a remotely controllable inoculant addition device for cast iron. The device uses a drive motor to rotate the collection cylinder to the bottom of the storage cylinder containing the inoculant to be added. Then, the valve at the bottom of the storage cylinder is opened, and the inoculant to be added falls to the top of the support plate for weighing. Then, the cylinder controls the push plate to push the inoculant into the cast iron equipment, thus allowing the addition of the required type of inoculant.

[0004] Although this device can add different types of inoculants separately, these inoculants are added to different casting equipment. This makes it impossible to guarantee that the inoculants will be thoroughly and evenly mixed when added to the casting equipment. While some devices use a screw conveyor for stirring the inoculant, the inoculant, under the influence of gravity, cannot fully contact the stirring rod during the screw stirring process, resulting in incomplete mixing. Incompletely mixed inoculants added to the casting equipment can lead to defects in the casting, such as abnormal graphite morphology and significant differences in mechanical properties between different parts. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide an automatic weighing and adding device that automatically weighs different types of inoculants, mixes them thoroughly and evenly, and then adds them to the casting equipment, thereby avoiding the impact of insufficient mixing of inoculants on the performance of the castings.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] An automatic weighing and adding device for inoculants includes a mounting frame, a feeding hopper, a mixing hopper, and a storage hopper mounted on the mounting frame. The feeding hopper, mixing hopper, and storage hopper are connected in sequence. The mixing hopper has a mixing chamber formed by a structural plate inside. A discharging chamber is provided at the bottom of the mixing chamber. The bottom of the mixing chamber has a concave arc structure, with the top and bottom ends of the concave arc being the top and bottom ends, respectively. A mixing component is provided at the bottom end of the concave arc in the mixing chamber. A discharge component is provided at the bottom of the mixing chamber. The mixing component includes a mixing shaft rotatably mounted on the mixing hopper and a stirring rod sleeved on the mixing shaft. The discharge component includes a discharge shaft rotatably mounted on the mixing hopper, a discharge arc plate provided at the bottom of the mixing chamber, and connecting rods provided on both sides of the discharge arc plate.

[0008] The present invention is further configured such that: the bottom of the structural plate is provided with an arc-shaped part, and the inner wall of the arc-shaped part is in contact with the stirring rod.

[0009] The present invention is further configured such that: a first bearing is connected to both ends of the mixing shaft, the first bearing is installed on the side wall of the mixing silo, and a motor is connected to one end of the mixing shaft.

[0010] The present invention is further configured such that: a second bearing is connected to both ends of the unloading shaft, a rocker arm is connected to one end of the unloading shaft, and a cylinder is connected to the end of the rocker arm.

[0011] The present invention is further configured such that: the connecting rod is connected to the unloading shaft, and the shape of the unloading arc plate is in contact with the arc direction of the bottom of the mixing chamber.

[0012] By adopting the above technical solution, the cylinder extension and retraction can drive the swing arm to rotate, and the swing arm rotation synchronously drives the unloading shaft to rotate. The unloading arc plate rotates synchronously with the unloading shaft, and the rotation of the unloading arc plate realizes the closing and opening of the bottom of the mixing chamber, thereby realizing the connection and closure between the mixing chamber and the discharge chamber.

[0013] The present invention is further configured such that: a plurality of first connectors are arranged around the side wall of the feeding hopper, and a first weighing sensor is provided at the bottom of each first connector.

[0014] The present invention is further configured such that: the top of the storage silo is provided with a first butterfly valve connected to the bottom of the mixing silo, and the bottom of the storage silo is provided with a second butterfly valve.

[0015] The beneficial effects of this utility model are:

[0016] A stirring rod is installed at the bottom of the mixing chamber. After the discharge arc plate closes the bottom of the mixing chamber, the stirring rod rotates to stir the inoculant in the mixing chamber. During the stirring process, the inoculant will fall to the stirring rod under the action of gravity, thereby increasing the contact area between the inoculant and the stirring rod, ensuring that the inoculant can be fully stirred and mixed evenly, and avoiding the impact on the performance of the casting due to insufficient mixing of the inoculant during the subsequent gold refining process.

[0031] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0032] Please refer to Figure 1-2An automatic weighing and adding device for inoculants includes a mounting frame 1, a feeding hopper 2, a mixing hopper 3, and a storage hopper 6 mounted on the mounting frame 1. The feeding hopper 2, mixing hopper 3, and storage hopper 6 are connected in sequence. The mixing hopper 3 is equipped with a mixing component 4 and a discharging component 5. Different types of inoculants are added to the feeding hopper 2, weighed, and then mixed in the mixing hopper 3 by the mixing component 4. After mixing, the discharging component 5 releases the inoculant into the storage hopper 6 for storage, and finally, the inoculant is instantly added to the casting equipment through the storage hopper 6.

[0033] Please refer to Figure 1-2 The mounting frame 1 is provided with a first mounting platform 11 and a second mounting platform 12, with the first mounting platform 11 located on top of the second mounting platform 12. The feeding hopper 2 is installed on the first mounting platform 11, the storage hopper 6 is installed on the second mounting platform 12, and the mixing hopper 3 is located between the feeding hopper 2 and the storage hopper 6.

[0034] Please refer to Figure 1-3 The feeding hopper 2 has multiple first connectors 23 arranged around its sidewalls. Each first connector 23 has a first weighing sensor 24 at its bottom, and the first weighing sensor 24 is mounted on the first mounting platform 11. The top of the feeding hopper 2 has a first feeding port 21 and a second feeding port 22. The feeding hopper 2 has a feeding chamber 25 inside, and the first feeding port 21 and the second feeding port 22 are connected to the feeding chamber 25. Different types of inoculants can be added to the feeding chamber 25 through the first feeding port 21 and the second feeding port 22, respectively. When the inoculant is added, the first weighing sensor 24 can measure the weight of the inoculant added to the feeding hopper 2, completing automatic weighing during the inoculant addition process.

[0035] Please refer to Figure 2-7 The mixing chamber 3 contains a mixing cavity 31 formed by structural plates 32. The structural plates 32 are arranged from the top of the mixing chamber 3 downwards, and four structural plates 32 are interconnected to form a mixing cavity 31 that gradually decreases in size from the top of the mixing chamber 3 downwards. The mixing cavity 31 is connected to the feeding cavity 25, allowing the inoculant in the feeding cavity 25 to enter the mixing cavity 31 under gravity. The bottom of the mixing cavity 31 has a concave arc structure, with the top and bottom ends of the concave arc being the top and bottom ends, respectively. The top end is located near the top of the mixing cavity 31, and the bottom of the structural plates 32 has an arc-shaped portion 33. A mixing assembly 4 is located inside the mixing cavity 31 at the bottom end of the concave arc, and a discharge assembly 5 is located at the bottom of the mixing cavity 31. A discharge cavity 34 is located at the bottom of the mixing cavity 31. During inoculant mixing, the discharge assembly 5 separates the mixing cavity 31 and the discharge cavity 34 to facilitate mixing. After mixing is complete, the discharge assembly 5 rotates to connect the mixing cavity 31 and the discharge cavity 34, allowing the mixed inoculant to fall into the discharge cavity 34.

[0036] Please refer to Figure 2-7The unloading assembly 5 includes an unloading shaft 54 ​​rotatably mounted on the mixing silo 3, an unloading arc plate 56 disposed at the bottom of the mixing chamber 31, and connecting rods 55 disposed on both sides of the unloading arc plate 56. The unloading shaft 54 ​​passes through the mixing silo 3, and two second bearings 53 are connected to both ends of the unloading shaft 54. The two second bearings 53 are respectively installed on the side wall of the mixing silo 3, allowing the unloading shaft 54 ​​to rotate relative to the mixing silo 3. One end of the unloading shaft 54 ​​is connected to a rocker arm 52, which is disposed on the outer wall of the mixing silo 3, and a cylinder 51 is connected to the end of the rocker arm 52. The side wall of the mixing silo 3 is provided with a housing for installing the unloading assembly 5, and the cylinder 51 is installed inside the housing. The output end of the cylinder 51 is rotatably connected to the rocker arm 52, and the other end of the cylinder 51 is rotatably connected to the housing via connecting rods. The extension and retraction of the cylinder 51 can drive the rocker arm 52 to rotate, and the rotation of the rocker arm 52 can synchronously drive the unloading shaft 54 ​​to rotate.

[0037] Please refer to Figure 2-7 The discharge arc plate 56 has a circular arc structure, and its shape conforms to the circular arc direction of the bottom of the mixing chamber 31. The discharge arc plate 56 enables the bottom of the mixing chamber 31 to be closed and opened, thereby achieving the connection and closure between the mixing chamber 31 and the discharge chamber 34. The connecting rod 55 is connected to the discharge shaft 54, connecting the discharge arc plate 56 and the discharge shaft 54, allowing the discharge arc plate 56 to rotate synchronously with the discharge shaft 54.

[0038] Please refer to Figure 2-7 The mixing assembly 4 includes a mixing shaft 42 rotatably mounted on the mixing hopper 3 and a stirring rod 43 sleeved on the mixing shaft 42. First bearings 44 are connected to both ends of the mixing shaft 42 and are mounted on the side wall of the mixing hopper 3, allowing the mixing shaft 42 to rotate relative to the mixing hopper 3. A motor 41 is connected to one end of the mixing shaft 42. A housing for mounting the mixing assembly 4 is provided on the side wall of the mixing hopper 3, and the motor 41 is installed inside the housing. The inner wall of the arc-shaped portion 33 is in contact with the stirring rod 43. The motor 41 can drive the mixing shaft 42 to rotate, and during the rotation of the mixing shaft 42, it can synchronously drive the stirring rod 43 to rotate, thereby stirring the inoculant inside the mixing chamber 31. The contact between the arc-shaped portion 33 and the stirring rod 43 prevents the inoculant from splashing upwards.

[0039] Please refer to Figure 1-3The storage silo 6 has multiple second connectors 64 arranged around its sidewalls, each second connector 64 having its bottom connected to a second mounting platform 12. The storage silo 6 has a storage chamber 64 inside, which communicates with the discharge chamber 34, allowing the mixed inoculant to enter the storage chamber 64 from the discharge chamber 34. The top of the storage silo 6 has a first butterfly valve 61 connected to the bottom of the mixing silo 3, and the bottom of the storage silo 6 has a second butterfly valve 62. The bottom of the storage silo 6 is connected to the casting equipment (not shown in the figure). The first butterfly valve 61 can connect or close the discharge chamber 34 and the storage chamber 64, and the second butterfly valve 62 can connect or close the storage chamber 64 and the casting equipment.

[0040] Specifically, when adding inoculants, one type of inoculant is first added to the feeding chamber 25 sequentially through the first feeding port 21 and the second feeding port 22. The first weighing sensor 24 measures the weight of the inoculant added to the feeding hopper 2. After weighing the first type of inoculant, the inoculant in the feeding chamber 25 can enter the mixing chamber 31 under gravity. The above steps are repeated to add different types of inoculants sequentially, completing the automatic weighing of different types of inoculants. After the inoculant enters the mixing chamber 31, the cylinder 51 extends and retracts, driving the swing rod 52 to rotate. The swing rod 52 synchronously drives the unloading shaft 54 ​​to rotate, causing the unloading arc plate 56 to seal the bottom of the mixing chamber 31. Then, the motor 41 drives the mixing shaft 42 to rotate, synchronously driving the stirring rod 43 to rotate and mix the inoculant inside the mixing chamber 31.

[0041] After different types of inoculants are automatically weighed, they enter the mixing chamber 31. When the discharge arc plate 56 closes the bottom of the mixing chamber 31, the stirring rod 43 rotates to stir the inoculants in the mixing chamber 31. The stirring rod 43 is set at the bottom of the mixing chamber 31. During the stirring process, the inoculants will fall to the stirring rod 43 under the action of gravity, thereby increasing the contact area between the inoculants and the stirring rod 43, ensuring that the inoculants can be fully stirred and mixed evenly, and avoiding the impact of insufficient mixing of inoculants on the performance of castings during the subsequent gold refining process.

[0042] After mixing, the discharge arc plate 56 rotates to open the bottom of the mixing chamber 31, and simultaneously opens the storage hopper 6 through the first butterfly valve 61, connecting the mixing chamber 31 and the discharge chamber 34. The mixed inoculant passes through the discharge chamber 34 into the storage chamber 64 for storage. When it is necessary to add inoculant to the casting equipment, the casting equipment is connected through the second butterfly valve 62, and the inoculant is instantly added to the casting equipment.

[0043] Different types of inoculants are automatically weighed and then enter the mixing silo 3. The discharge arc plate 56 seals the bottom of the mixing chamber 31, and the mixing is carried out using the stirring rod 43. After mixing is completed, the discharge arc plate 56 rotates to open the bottom of the mixing chamber 31, allowing the inoculant to enter the storage silo 6 for storage. When it is necessary to add inoculant to the casting equipment, the inoculant in the storage silo 6 is added to the casting equipment instantly, thereby effectively avoiding the inoculant degradation caused by the gradual addition of inoculant to the casting equipment during the stirring process, and further improving the performance of the casting.
