Description

Technical Field

[0001] This utility model relates to the field of molding sand mixing technology, specifically to a molding sand mixing device for grooved pipe fittings. Background Technology

[0002] In the production of wear-resistant steel, casting is an extremely important processing technology. For example, in the casting of grooved pipe fittings, solid metal is melted into liquid, and then the molten metal is poured into a mold to cool and solidify to obtain the casting. The molding sand used in the casting mold is usually made by adding a certain proportion of binder or other auxiliary materials to fine sand and then stirring it evenly. Since wear-resistant steel must avoid defects such as porosity and inclusions in the casting, the uniformity of the molding sand used in the casting mold is required to be extremely high.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222778796U, which discloses a foundry sand mixing device. The device includes a mixing chamber and a stirring mechanism installed inside the mixing chamber. A screening mechanism is installed inside the mixing chamber, above the stirring mechanism. The screening mechanism includes a drive component installed outside the mixing chamber. The drive component is fixedly connected to a first screen frame via a transmission component. A cleaning component fixed to the inner wall of the mixing chamber is installed inside the first screen frame. The transmission component includes a splined shaft; one end of the splined shaft is fixedly connected to the output end of the drive component, and the other end is movably fitted with a splined sleeve. The end of the splined sleeve away from the splined shaft is fixedly connected to the first screen frame. This utility model's drive component, through the cooperation of the transmission component and the feed pipe, can drive the first screen frame to rotate and vibrate, thereby enabling rapid screening of the foundry sand raw material. Fine sand particles are screened onto the stirring mechanism for mixing, which not only improves production efficiency but also ensures the quality of the foundry sand.

[0004] Although this device can quickly screen the raw material of casting sand, sending fine sand particles to the mixing mechanism for mixing, thus improving production efficiency, its feed inlet cannot allow the material to fall in weight. Directly pouring a large amount of raw material into the mixing box can easily cause subsequent raw materials to pile up, resulting in a longer mixing time and lower mixing efficiency.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0018] like Figure 1-4 As shown, an embodiment of this utility model provides a molding sand mixing device for grooved pipe fittings, comprising: a base 1; The mixing cylinder 2 is fixedly installed on the top of the base 1. The mixing cylinder 2 is equipped with a stirring component 3 for stirring materials. The top of the mixing cylinder 2 is provided with a liquid injection port and the bottom is provided with a discharge port.

[0019] Feed frame 4 is fixedly installed on the top of the mixing cylinder 2. A dispensing cylinder 5 is fixedly installed on the bottom of the feed frame 4. The dispensing cylinder 5 is connected to the feed frame 4. A dispensing component 6 for dispensing material is installed on the dispensing cylinder 5. A scattering frame 7 is fixedly installed at the bottom end of the dispensing cylinder 5, and is interconnected with the dispensing cylinder 5. A dispersing hopper 8 is installed between the two sides of the inner wall of the scattering frame 7, and a shaking component 9 for shaking the dispersing hopper 8 is installed on the scattering frame 7. The scattering frame 7 is interconnected with the mixing cylinder 2. In the background art, the screening mechanism can be set at the top of the feed frame 4, and the sieving is followed by a fractional drop.

[0020] The molding sand raw material to be mixed first enters the dispensing cylinder 5 through the feed frame 4 fixed to the top of the mixing cylinder 2. The dispensing component 6 set in the dispensing cylinder 5 dispenses the raw material according to the preset, so that the material falls continuously in a controllable and dispersed flow, avoiding the accumulation phenomenon caused by a large amount of material being fed at once. After dispensing, the raw material falls into the scattering frame 7 connected to the dispensing cylinder 5, and then falls into the dispersing hopper 8. The dispersing hopper 8 set in the scattering frame 7 generates high-frequency micro-vibration under the drive of the shaking component 9, further evenly dispersing the raw material and scattering it into the mixing cylinder 2 below. At the same time, the stirring component 3 in the mixing cylinder 2 makes the various raw materials reach a uniform mixing state in a short time. Through the cooperation between the dispensing cylinder 5, the dispensing component 6, the scattering frame 7, the dispersing hopper 8 and the shaking component 9, the falling raw material is dispensed multiple times, which maximizes the production efficiency while ensuring the quality of the molding sand, and avoids the defects of material accumulation and difficulty in stirring caused by excessive material feeding at once, resulting in long stirring time and low efficiency.

[0021] like Figure 3 As shown, in some embodiments, the stirring assembly 3 includes a drive motor 31 fixedly installed at the bottom of the base 1, a rod 34 rotatably installed at the bottom of the inner wall of the mixing cylinder 2, one end of the rod 34 being fixedly connected to the output end of the drive motor 31, and multiple horizontal plates 32 fixedly installed in an array on the outer periphery of the rod 34, with inclined plates 33 fixedly installed symmetrically at the bottom of each of the multiple horizontal plates 32.

[0022] After the component 6 and the shaking component 9 have evenly sprinkled the molding sand into the mixing cylinder 2 at the set flow rate, the drive motor 31 fixed at the bottom of the base 1 starts and directly drives the rod 34, which is vertically inserted into the bottom of the inner wall of the mixing cylinder 2, to rotate at high speed through the output end. Multiple horizontal plates 32 fixed in an array on the outer periphery of the rod 34 move horizontally in a circular motion with the rod 34. The inclined plates 33 symmetrically fixed at the bottom of the horizontal plates 32 form a shearing inclined plane with a certain angle to the horizontal plane, so that the raw materials are quickly stirred and mixed in a short period of time.

[0023] like Figure 3 As shown, in some embodiments, scrapers 10 are fixedly installed between one side of the plurality of horizontal plates 32, and the side of the scrapers 10 is in contact with the inner wall of the mixing cylinder 2.

[0024] By having the scraper 10 adhere to the inner wall of the mixing cylinder 2, the inner wall of the mixing cylinder 2 is self-cleaning, preventing raw materials from adhering to the inner wall and reducing the mixing effect.

[0025] like Figure 3 As shown, in some embodiments, an arc-shaped plate 11 is fixedly installed on one side of each of the multiple horizontal plates 32, and the arc-shaped plate 11 has multiple openings arranged in an array.

[0026] During the mixing process, the rod 34 drives the horizontal plate 32, the inclined plate 33 and the scraper 10 to rotate synchronously. At the same time, the arc plate 11 fixed on the side of each horizontal plate 32 also moves. Its curved surface faces the direction of rotation to form a material-collecting arc surface. The array of openings acts as an instantaneous discharge channel. When the horizontal plate 32 pushes the molding sand to move radially, some sand particles are intercepted by the arc plate 11 and accumulate briefly in the arc surface. As the rotation speed increases, the thickness of the accumulation layer increases. Under the centrifugal force and the guiding action of the arc surface, the sand particles are continuously squeezed and sprayed out in the form of a high-speed jet through the opening, and then mixed and stirred to further mix the raw materials in the mixing cylinder 2.

[0027] like Figure 3 As shown, in some embodiments, the component assembly 6 includes a rotating motor 61 fixedly installed on one side of the component cylinder 5, a component plate 62 rotatably installed between the two sides of the inner wall of the component cylinder 5, the outer periphery of the component plate 62 being in contact with the inner wall of the component cylinder 5, and the output end of the rotating motor 61 being fixedly connected to one side of the component plate 62.

[0028] The dispensing plate 62 divides the dispensing cylinder 5 into upper and lower layers. Since the dispensing cylinder 5 is connected to the feeding frame 4, the raw material falls to the upper layer. When it is necessary to drop some raw material, the rotating motor 61 is started to drive the dispensing plate 62 to rotate 180°, so that the raw material moves with the dispensing plate 62 and enters the lower space. Since the dispensing cylinder 5 is connected to the scattering frame 7, the raw material falls directly into the scattering frame 7.

[0029] like Figure 3 As shown, in some embodiments, the shaking component 9 includes a vibration motor 91 fixedly mounted on the feed frame 4. The output end of the vibration motor 91 is fixedly connected to one side of the scattering frame 7. Multiple shaking springs 92 are fixedly installed between the two sides of the inner wall of the scattering frame 7 and the two sides of the dispersing hopper 8. The top opening of the dispersing hopper 8 is larger than the opening connecting the distributing cylinder 5 and the scattering frame 7, preventing the falling material from scattering inside the scattering frame 7.

[0030] The dispersing hopper 8 is suspended by a shaking spring 92, and then the dispersing frame 7 is driven to vibrate by a vibration motor 91, which in turn drives the dispersing hopper 8 to shake. This prevents the falling raw materials from accumulating and becoming difficult to fall. The dispersing hopper 8 can further disperse the falling raw materials, making it easier for subsequent mixing.

[0031] like Figure 3 As shown, in some embodiments, support plates 12 are fixedly installed on both sides of the inner wall of the scattering frame 7, and the bottom of the scattering hopper 8 is slidably connected to the top of the support plate 12.

[0032] The movement direction of the dispersing hopper 8 is restricted by the support plate 12, so that it can only shake horizontally and left and right, but not vertically, to avoid shaking up and down and scattering materials.

[0033] like Figure 2 As shown, in some embodiments, two shock-absorbing and anti-slip mats 13 are symmetrically distributed and fixedly installed at the bottom of the base 1.

[0034] The shock-absorbing and anti-slip mat 13 is used to reduce the vibration amplitude of the entire device on the placement platform and prevent it from moving.

[0035] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
