Description

Technical Field

[0001] The utility model relates to the technical field of mixing devices, and more specifically, to a mixing bin for the production of special alloy materials. Background Art

[0002] Special alloy materials refer to alloy materials with special functions or properties, usually composed of two or more metal elements. They can be divided into various types, such as superalloys, corrosion-resistant alloys, superhard alloys, etc. Special alloy materials need to be made into products of different shapes according to different requirements in the later stage of production to meet the usage requirements. Many alloys have extremely high requirements for metal purity during the manufacturing process, especially for non-ferrous metals such as aluminum, copper, and zinc and their alloys.

[0003] When materials need to be processed, a special mixing bin is required for material storage, which can make material storage more efficient and safe. With the help of the bin, material transportation and transfer can be better carried out. As a storage structure for materials, the bin can well maintain the chemical stability of the materials.

[0004] In the Chinese utility model patent application number: CN216295966U, an alloy raw material mixing device is disclosed, and the structure includes: a mixing box, a mixing component is arranged inside the mixing box, a feeding pipe is arranged on one side of the top of the mixing box, a discharge pipe is communicated with the bottom of the mixing box, a valve is arranged at one end of the discharge pipe close to the mixing box, and a dust removal component is also arranged on the discharge pipe. The dust removal component includes: a dust suction pipe, one end of the dust suction pipe is communicated with the discharge pipe and is provided with a filter screen, and a dust collection box is arranged at one end of the discharge pipe far from the exhaust fan. This alloy raw material mixing device has the ability to mix metal raw materials, but lacks a structure that can prevent internal dust from escaping and prevent external water vapor from entering the mixing device when adding additives.

[0005] Now, various additives are indeed often needed during the smelting and processing of metal raw materials. These additives are mainly used to improve process performance, improve product quality, or endow metal materials with specific functions. However, when adding additives to the current mixing device, the inside of the mixing device will be in communication with the outside through the feeding pipe, resulting in the internal metal dust running out to the outside and polluting the nearby environment. At the same time, external water vapor will enter the inside of the mixing device through the feeding pipe, affecting the oxidation of the metal raw materials.

[0006] Therefore, it is very necessary to propose a mixing bin for the production of special alloy materials to solve the above problems. Summary of the Utility Model

[0007] The purpose of the present utility model is to provide a mixing bin for the production of special alloy materials in order to solve the problems raised in the above-mentioned background technology.

Detailed implementation manners

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1-9, A mixing bin for producing special alloy materials, including a mixing tank 101. The bottom of the mixing tank 101 is provided with a discharge port, and the top is connected to a feed pipe 129 through a top cover 127. A feeding pipe 102 is fixedly connected to the side wall of the mixing tank 101. Different feed pipes 129 are connected to different raw material tanks, capable of adding different types of metal raw materials. The top end of the feeding pipe 102 is connected to a manhole cover 103. The manhole cover 103 includes a cross bar 104, an upper cover 105, and a nut 106. The manhole cover 103 is the inlet valve of the feeding pipe 102, facilitating the user to add additives into the mixing tank 101 through the feeding pipe 102. The cross bar 104 and the upper cover 105 are hinged. A support platform 107 is arranged inside the upper cover 105, and the support platform 107 is used to place a driving wheel 108 and a driven wheel 109. A driving wheel 108 and a driven wheel 109 that cooperate with each other are rotatably connected to the support platform 107. The driving wheel 108 is connected to an adjusting handle 123. The driven wheel 109 is splined to a connecting frame 111 through a spline block 110. The other end of the connecting frame 111 is connected to an external spline 112. A spline block 110 is fixedly connected to the bottom of the driven wheel 109. The external spline 112 can slide up and down on the outer wall of the spline block 110 through the connecting frame 111. The connecting frame 111 is slidably connected up and down on the outer wall of the spline block 110. The bottom of the connecting frame 111 is fixedly connected to an external spline 112. The external spline 112 is matched with an internal spline 122 through spline connection. A support plate 113 sleeved on the outer wall of the spline block 110 is fixedly connected to the support platform 107. A spring 114 is connected between the external spline 112 and the support plate 113;

[0034] Reference Figure 4 and Figure 6 , An upper support plate 115, an inclined plane ring 116, and a lower support plate 117 are fixedly connected to the inner wall of the feeding pipe 102 from top to bottom in sequence. The upper support plate 115 is used to support the threaded sleeve 121, enabling the threaded sleeve 121 to move up and down. The inclined plane ring 116 is provided with a double inclined plane. The top inclined plane is used to guide the additive towards the baffle plate 119, and the bottom inclined plane cooperates with the baffle plate 119 to block the connection of the feeding pipe 102. A spline rod 118 is slidably connected to the inner ring surface of the lower support plate 117 up and down. The spline rod 118 is used to limit the up and down sliding of the baffle plate 119 and prevent it from rotating. A baffle plate 119 is fixedly connected to the top of the spline rod 118. The baffle plate 119 is provided with a conical inclined plane, which can cooperate with the bottom of the inclined plane ring 116. A spring 114 is connected between the baffle plate 119 and the lower support plate 117. When the spring 114 resets, it pushes the baffle plate 119 upwards, causing the top threaded sleeve 121 to be pushed out of the feeding pipe 102. A threaded rod 120 is fixedly connected to the top of the baffle plate 119, and the top of the threaded rod 120 is threadedly connected to a threaded sleeve 121;

[0035] Reference Figures 4 to 6, at the top end of the threaded sleeve 121, there is an internally splined 122 that mates with the externally splined 112. When the externally splined 112 and the internally splined 122 are connected together, they will drive each other to rotate. On the outer wall of the threaded sleeve 121, there is a sliding groove that mates with the upper support plate 115.

[0036] Specifically, referring to Figures 4 to 6 , on both the upper and lower ends of the inclined surface ring 116, there are inclined surfaces. The inclined surface at the top guides the additive towards the position of the retaining plate 119, and the inclined surface at the bottom is used to contact the retaining plate 119. On the outer wall of the retaining plate 119, there is an inclined surface that fits closely with the inclined surface at the bottom of the inclined surface ring 116.

[0037] Specifically, referring to Figure 3 , on one side of the top of the feeding pipe 102, it is hinged to the cross bar 104. One end of the cross bar 104 is hinged to the feeding pipe 102, and the other end can be fixed to the feeding pipe 102 through the nut 106. The middle part is hinged to the upper cover 105, and the other side is hinged to the nut 106. On the cross bar 104, there is a groove for fixing the nut 106.

[0038] Specifically, referring to Figures 7 to 9 , on one side of the driving wheel 108, there is an adjusting handle 123 that extends out of the upper cover 105. By rotating the adjusting handle 123, the driving wheel 108 can be driven to rotate. Inside the connecting frame 111, there is a cavity for accommodating the spline block 110.

[0039] Specifically, referring to Figure 1 and Figure 2 , outside the mixing tank 101, there is a bench 124. The bench 124 is used to support the mixing tank 101, and between the mixing tank 101 and the support feet 125, there is a weighing device 126 for weighing the weight of the mixing tank 101. On the outer wall of the mixing tank 101, there are support feet 125 arranged in a circumferential array. At the bottom of the support feet 125, there is a weighing device 126 fixed, and the weighing device 126 is fixed to the bench 124.

[0040] Specifically, referring to Figure 1 and Figure 2 , on the top of the mixing tank 101, there is a top cover 127. The top cover 127 is fixed to the mixing tank 101 through multiple buckles. On the top cover 127, there is a driving device 128 and a feeding pipe 129 installed.

[0041] Specifically, referring to Figure 1 and Figure 2 , at the output end of the driving device 128, there is a stirring rod 130 fixed. The stirring rod 130 extends into the mixing tank 101 for stirring the metal raw materials, and the stirring rod 130 is located inside the mixing tank 101.

[0042] In this embodiment, multiple feed pipes 129 are connected to the top of the mixing tank 101. Different types of metal raw materials can be added through the feed pipes 129 at the top. After the raw materials enter the interior of the mixing tank 101, the driving device 128 at the top of the top cover 127 is started. The output end of the driving device 128 drives the stirring rod 130 to stir inside the mixing tank 101, enabling various raw materials to be mixed. The mixing tank 101 is fixed on the bench 124 through the support feet 125 on the outer wall. The weighing device 126 at the bottom of the support feet 125 can weigh the weight of the mixing tank 101 to facilitate controlling the mass ratio of each material. The feeding pipe 102 on the side wall of the mixing tank 101 communicates with the interior of the mixing tank 101, and additives can be added into the mixing tank 101 by opening the manhole cover 103 above;

[0043] Solution 1: When additives need to be added into the mixing tank 101, first open the manhole cover 103 at the top of the feeding pipe 102, loosen the nut 106 on the feeding pipe 102, and open the upper cover 105 through the cross bar 104. When the upper cover 105 is opened, the spring 114 between the lower support plate 117 and the retaining plate 119 extends, pushing the top retaining plate 119 upward, causing the retaining plate 119 to abut against the bottom of the inclined surface ring 116, thereby blocking the middle position of the feeding pipe 102 and interrupting the connection between the interior of the mixing tank 101 and the outside. When the retaining plate 119 moves upward, the threaded sleeve 121 is driven upward through the threaded rod 120 at the top. The top end of the threaded sleeve 121 and the internal spline 122 will extend out of the feeding pipe 102, and the additives to be added are poured into the feeding pipe 102. The additives will be blocked at the top of the inclined surface ring 116;

[0044] After the addition is completed, cover the manhole cover 103 on the feeding pipe 102 again. When the upper cover 105 covers the feeding pipe 102, the external spline 112 inside will be on the same axis as the internal spline 122 at the top of the threaded sleeve 121, and the external spline 112 will be inserted into the internal spline 122. Subsequently, the retaining plate 119 is pressed down through the threaded sleeve 121, and the spring 114 between the retaining plate 119 and the lower support plate 117 is compressed. At this time, the retaining plate 119 disengages from the bottom of the inclined surface ring 116, enabling the additives to enter the mixing tank 101 through the gap between the inclined surface ring 116 and the retaining plate 119;

[0045] Solution 2: The additive can also be pre-stored in the feeding pipe 102. When addition is required, it is added into the mixing tank 101 through the adjusting handle 123 at the top of the upper cover 105. When the manhole cover 103 is not opened, first rotate the adjusting handle 123. The adjusting handle 123 drives the driving wheel 108 at the bottom to rotate. The driving wheel 108 drives the external spline 112 to rotate through the driven wheel 109. The external spline 112 is spline-connected to the internal spline 122, thereby driving the internal spline 122 to rotate. The internal spline 122 drives the threaded sleeve 121 at the bottom to rotate on the threaded rod 120. Since the threaded sleeve 121 is sleeved on the threaded rod 120 and is threadedly connected to the threaded rod 120, when the threaded sleeve 121 rotates, the threaded rod 120 moves upward through the thread, which is equivalent to shortening the total length of the threaded rod 120 and the threaded sleeve 121. When the threaded rod 120 and the threaded sleeve 121 are shortened to a certain length, the stop disc 119 will contact the bottom of the inclined surface ring 116. At this time, open the manhole cover 103. Due to the length reason, the threaded sleeve 121 will not extend out of the feeding pipe 102. At this time, the additive can be poured into the feeding pipe 102, and then close the manhole cover 103;

[0046] When the addition of the additive is required, reverse the adjusting handle 123 to reverse the threaded sleeve 121, thereby lengthening the length of the threaded sleeve 121 and the threaded rod 120. At this time, the distance between the stop disc 119 and the inclined surface ring 116 becomes larger, and the additive enters the mixing tank 101 from the gap to complete the addition of the additive. It should be noted that when the manhole cover 103 covers the feeding pipe 102 and the external spline 112 is not inserted into the internal spline 122, the spring 114 between the external spline 112 and the support plate 113 is compressed. The external spline 112 slides up and down on the outer wall of the spline block 110 through the connecting frame 111 at the top, and then is inserted into the internal spline 122 as the external spline 112 rotates.

[0047] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art on the basis of the present invention belong to the scope of protection required by the present invention.
