Description

Technical Field

[0001] This utility model belongs to the field of coated sand production technology, and in particular relates to a high-temperature resistant and anti-collapse coated sand production equipment. Background Technology

[0002] Coated sand is a molding and core-making material widely used in the foundry industry. It is made by "wrapping" a thin and uniform phenolic resin film on the surface of base sand grains. The production process of coated sand is preheating, sand mixing, coating, cooling, secondary sand mixing, and secondary cooling. In order to facilitate the production of coated sand, production equipment is usually used. A document with the existing authorization announcement number CN220782151U discloses a coating sand raw sand coating equipment, including a mixing box and a stirring chamber disposed in the mixing box. The stirring chamber is provided with a stirring mechanism for stirring raw materials. The stirring mechanism includes a drive motor fixedly installed on the mixing box. A reciprocating screw is fixedly installed at the output end of the drive motor. A threaded sleeve is threaded on the outside of the reciprocating screw. A limiting sleeve that slides with the mixing box is fixedly installed at the upper end of the threaded sleeve. A lifting block is rotatably installed at the lower part of the threaded sleeve. A cross groove is opened in the reciprocating screw. However, it still has the following drawbacks in practical use: The aforementioned coating equipment uses a stirring mechanism to mix raw materials such as sand and resin in a mixing tank, and adds the raw materials such as resin to the inside of the mixing tank through feeding pipes on both sides of the mixing tank. However, during use, because the position of the feeding pipes in the mixing tank is fixed, the feeding position of the raw materials such as resin is also fixed. Due to the fixed feeding position, the raw materials such as resin and sand are not mixed sufficiently, resulting in poor mixing effect and thus unsatisfactory coating effect. The aforementioned coating equipment uses a stirring mechanism to mix raw materials such as sand and resin in a mixing tank, and adds the raw materials such as resin to the inside of the mixing tank through feeding pipes on both sides of the mixing tank. However, during use, after the coating cools down, some sand particles will stick together. The aforementioned coating equipment is not convenient for crushing the sticky sand particles, making it inconvenient for subsequent processing.

[0003] To address these issues, we provide a high-temperature resistant and anti-collapse coated sand production equipment. Utility Model Content

Detailed Implementation

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example 1

[0028] Please see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The first embodiment of this utility model is shown, which provides a high-temperature resistant and anti-collapse coated sand production equipment, including a coating tank 1. The coating tank 1 is further equipped with a heating device for heating raw materials such as sand and resin. The heating device is preferably an electric heating structure. A cooling device is also provided for cooling the coated sand. The cooling device is preferably a jacketed cold water cooling structure. A mixing component 2 for mixing raw materials such as sand and resin in the coating tank 1 is provided on the top of the coating tank 1. The mixing component 2 includes a tank cover 201, a stirring blade 202, a fixing ring 203, and a material cylinder 205. The fixing ring 203 drives the tank cover 201 and the material cylinder 205 to rotate, thereby uniformly adding raw materials such as resin into the coating tank 1. The stirring blade 202 stirs and mixes the raw materials such as sand and resin, solving the problem of insufficient mixing of raw materials such as sand and resin in existing systems.

[0029] Specifically, the can lid 201 is rotatably connected to the top of the coating tank 1. The can lid 201 is used to seal the interior of the coating tank 1 and to install structures such as the stirring rod 202a. The stirring rod 202a is rotatably connected to the can lid 201 via bearings. The bottom end of the stirring rod 202a extends into the interior of the coating tank 1 and is fixedly connected to the stirring blades 202. The stirring blades 202 are used to stir and mix the raw materials such as sand and resin inside the coating tank 1. The top end of the stirring rod 202a extends above the can lid 201 and is fixedly connected to the driven gear 202b. The driven gear 202b is fixed to the stirring rod 202a via a keyway connection, driving the stirring rod 202a to rotate. Both sides of the top of the can lid 201 are fixedly connected. There is a material cylinder 205, which contains raw materials such as resin. The material cylinder 205 is used to add the raw materials such as resin to the coating tank 1 in a metered manner. A fixing ring 203 is fixedly connected to the top outer side of the tank cover 201. The fixing ring 203 is installed on the tank cover 201 by bolts. The fixing ring 203 is used to drive the tank cover 201 to rotate. An internal gear ring 203a is fixedly connected to the inner side wall of the fixing ring 203. The top rear end of the tank cover 201 is rotatably connected to a transmission gear 201b through a mounting base 201a. The transmission gear 201b meshes between the driven gear 202b and the internal gear ring 203a. The arrangement of the transmission gear 201b and the internal gear ring 203a realizes the transmission between the fixing ring 203 and the stirring rod 202a, and the rotation direction of the fixing ring 203 is opposite to the rotation direction of the stirring rod 202a.

[0030] Furthermore, a fixing plate 101 is welded to the rear end face of the coating tank 1. The fixing plate 101 is used to install the first drive motor 204. The first drive motor 204 is fixedly connected to the fixing plate 101 via a first motor bracket 204a. The first motor bracket 204a is used to mount the first drive motor 204 on the fixing plate 101. The output shaft of the first drive motor 204 is fixedly connected to a drive rod 204b. The first drive motor 204 is used to drive the drive rod 204b to rotate. The drive rod 204b is used to drive the fixed ring 203 to rotate. A drive gear 204c is fixedly connected to the drive rod 204b. An external gear ring 203b is fixedly connected to the outer wall of the fixed ring 203. The external gear ring 203b meshes with the front end of the drive gear 204c. The external gear ring 203b and the drive gear 204c are used to realize the transmission between the drive rod 204b and the fixed ring 203. The bottom of the material cylinder 205 is fixedly connected to a feeding pipe 205a. The bottom end of the feeding pipe 205a passes through the can cover 201 and extends to the upper part of the coating tank 1. The feeding pipe 205a is used to add the resin and other raw materials in the material cylinder 205 into the coating tank 1. The top of the material cylinder 205 is fixedly connected to a second drive motor 205b. The output shaft of the second drive motor 205b is fixedly connected to a rotating shaft 205c. The bottom end of the rotating shaft 205c extends into the inside of the feeding pipe 205a and is fixedly connected to an auger rod 205d. The second drive motor 205b and the rotating shaft 205c are used to drive the auger rod 205d to rotate. The auger rod 205d is used to quantitatively add the resin and other raw materials in the material cylinder 205 into the coating tank 1.

[0031] The operation process of this embodiment is as follows: First, the preheated sand is poured into the coating tank 1 and the tank lid 201 is closed. Then, the first drive motor 204 is started. The output shaft of the first drive motor 204 drives the drive rod 204b to rotate. The drive rod 204b drives the fixed ring 203 to rotate through the drive gear 204c and the external gear ring 203b. When the fixed ring 203 rotates, it drives the tank lid 201 and the internal gear ring 203a to rotate. The tank lid 201 drives the material cylinder 205 to rotate relative to the coating tank 1. The internal gear ring 203a drives the stirring rod 202a and the stirring blade 202 to rotate through the transmission gear 201b and the driven gear 202b. Thus, the stirring blade 202 pushes the sand raw material in the coating tank 1 to rotate. The mixture is stirred, and then the second drive motor 205b on the material cylinder 205 is started. The output shaft of the second drive motor 205b drives the auger rod 205d to rotate through the rotating shaft 205c. The rotation of the auger rod 205d adds a metered amount of resin raw material from the material cylinder 205 to the coating tank 1. Then, the heating device in the coating tank 1 is started to heat the sand, resin and other raw materials in the coating tank 1. With the rotation of the stirring blades 202, the resin melts and covers the surface of the sand, thus achieving the coating treatment of the sand. Finally, the heating device is turned off and the cooling device in the coating tank 1 is started to quickly cool the coated sand, thereby realizing the processing and production of coated sand. Example 2

[0032] Please see Figure 1 , Figure 2 , Figure 7 , Figure 8 , Figure 9 and Figure 10As shown, this is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs from the previous embodiment in that: a processing component 3 is provided below the coating tank 1. The processing component 3 includes a processing box 301, a screen 302, and a crushing roller 303. The crushing roller 303 in the processing box 301 crushes the coated sand particles, and the screen 302 screens the crushed coated sand, thus solving the problem that it is inconvenient to crush coated sand particles in the existing system.

[0033] Specifically, the processing box 301 is fixedly connected to the bottom of the coating tank 1. The processing box 301 is used to crush the coated sand particles. A screen 302 is fixedly connected inside the processing box 301. The screen 302 is U-shaped and is used to screen the coated sand to ensure that the coated sand particles are uniform after unloading. A third drive motor 303b is fixedly connected to the front end of the processing box 301 through a second motor frame 303a. The output shaft of the third drive motor 303b extends into the processing box 301 and is fixedly connected to a crushing roller 303. The crushing roller 303 is located inside the screen 302 and is used to crush the coated sand. The second motor frame 303a is used to install the third drive motor 303b, and the third drive motor 303b is used to drive the crushing roller 303 to rotate.

[0034] Furthermore, fixing rods 301a are welded to the top of the processing box 301 around the perimeter. The top of the fixing rods 301a is fixedly connected to the bottom perimeter of the coating tank 1. The fixing rods 301a are used to fix the processing box 301 to the bottom of the coating tank 1. The bottom center of the coating tank 1 is fixedly connected to a first discharge pipe 102. The bottom end of the first discharge pipe 102 extends to the upper part of the interior of the processing box 301. A first discharge valve 103 is fixedly connected to the first discharge pipe 102. The first discharge pipe 102 and the first discharge valve 103 are used to connect the internal space of the coating tank 1 and the internal space of the processing box 301. So when the first discharge valve 103 is opened, the coating sand in the coating tank 1 is added to the processing box 301 under the action of gravity. The bottom center of the processing box 301 is fixedly connected to a second discharge pipe 301b. The top end of the second discharge pipe 301b extends to the lower interior of the processing box 301, and the bottom end of the second discharge pipe 301b extends to the lower exterior of the processing box 301 and is fixedly connected to a second discharge valve 301c. The second discharge pipe 301b and the second discharge valve 301c are used to discharge the processed coated sand from the processing box 301. Both ends of the screen 302 are fixedly connected to L-shaped plates 302a. The horizontal support arms of the L-shaped plates 302a are fixedly connected to the top of the inner side of the processing box 301. The L-shaped plates 302a are fixed to the screen 302 and the processing box 301 by bolts. The L-shaped plates 302a are used to fix the screen 302 inside the processing box 301. A cooling box 306 is fixedly connected to the rear end face of the processing box 301 via an L-shaped frame 306a. An air inlet pipe 304 is fixedly connected to one side of the outer wall of the cooling box 306. One end of the air inlet pipe 304 extends into the interior of the cooling box 306 and is fixedly connected to a blower 304a. The other end of the air inlet pipe 304 extends into the interior of the processing box 301. A return air pipe 305 is fixedly connected to the other side of the outer wall of the cooling box 306. The end of the return air pipe 305 away from the cooling box 306 extends into the interior of the processing box 301 and is fixedly connected to a filter 305a. Multiple heat exchange fins 306b are fixedly connected at equal intervals inside the cooling box 306. Multiple ventilation holes 306c are opened at equal intervals on the front end of the outer wall of the heat exchange fins 306b. The rear end of the outer wall of the heat exchange fins 306b extends to the rear of the exterior of the cooling box 306 and passes through multiple heat exchange pipes 306d.

[0035] The rest of the structure is the same as in Example 1.

[0036] The operation process of this embodiment is as follows: After the coating is completed, the first discharge valve 103 is opened, so that under the action of gravity, the coating sand in the coating tank 1 falls into the processing box 301 through the first discharge pipe 102. Then, the third drive motor 303b is started. The output shaft of the third drive motor 303b drives the crushing roller 303 to rotate. The crushing roller 303 crushes the coating sand on the screen 302. After crushing, the coating sand with the standard particle size falls into the lower part of the processing box 301 through the screen 302. Then, the heat exchange tube 306d is connected to the cold water tank. The cold water cools the heat exchange fins 306b, which in turn cools the air inside the cooling box 306. At the same time, the blower 304a is started, and the cold air inside the cooling box 306 enters the processing box 301 through the air inlet pipe 304 under the action of the blower 304a, thereby achieving a second cooling treatment of the coated sand, so that the temperature of the coated sand is maintained at room temperature or within the standard temperature range. Finally, the second discharge valve 301c is opened, so that the processed coated sand flows out through the second discharge pipe 301b, realizing the crushing and other processing of the coated sand.
