Description

Technical Field

[0001] This utility model relates to the technical field of grease testing equipment, and more specifically, to a grease homogenizer. Background Technology

[0002] In existing technologies, lubricating greases need to be tested before production. The tests usually involve mixing small amounts of raw materials, and the tested greases also need to be stirred and homogenized. If a homogenizer used for mass production is used for homogenization, it typically involves friction between three rollers. The homogenized grease adheres to the rollers and is collected, eventually passing through a scraper. Because the amount of grease used in the tests is small, the loss of grease after homogenization is relatively high. Furthermore, the high energy consumption of large-scale equipment makes it unsuitable for homogenizing experimental greases. Therefore, a technical solution is needed to address these issues. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a grease homogenizer suitable for homogenizing small amounts of grease.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] This utility model discloses a grease homogenizer, including a mixing tank, a homogenizing device, and an output device. The mixing tank includes a tank body and a feed pipe, the feed pipe connecting the tank body and the homogenizing device. The homogenizing device includes a housing and an extrusion device. The housing includes multiple extrusion chambers, and the extrusion device includes multiple extrusion blocks, each extrusion block being at least partially located within an extrusion chamber and capable of sliding along the extrusion chamber. The housing has a first channel, a second channel, and a third channel. The connection ends of the first channel, the second channel, and the third channel with the extrusion chamber are located at ends away from the openings of the extrusion chambers. The first channel connects the feed pipe and the first extrusion chamber, the second channel connects two adjacent extrusion chambers, and the third channel connects the last extrusion chamber and the output device. The output device includes a housing, the housing having an output pipe and a fourth channel, the fourth channel connecting the output pipe and the third channel.

[0006] Furthermore, the extrusion block is provided with an extrusion groove, which is located on the side wall of the extrusion block facing the closed end of the extrusion cavity. The extrusion groove connects the end face of the extrusion block facing the closed end of the extrusion cavity and the second channel or the third channel.

[0007] Furthermore, the side wall of the extrusion block facing the closed end of the extrusion chamber is provided with a conical surface, the diameter of the part of the extrusion block with the conical surface gradually decreases towards the closed end of the extrusion chamber, and the inner wall of the extrusion chamber is provided with a conical surface corresponding to the conical surface of the extrusion block.

[0008] Furthermore, the second channel is closer to the closed end of the extrusion chamber than the first channel, one of the two second channels connecting the same extrusion chamber is closer to the closed end of the extrusion chamber, and the third channel is closer to the closed end of the extrusion chamber than the second channel.

[0009] Furthermore, the extrusion device includes a second motor and a drive rod. The second motor drives the drive rod to rotate. The drive rod and the extrusion block are connected by a connecting rod. The two ends of the connecting rod are rotatably connected to the drive rod and the extrusion block, respectively. The axial direction of the drive rod is perpendicular to the axial direction of the extrusion block. The drive rod has multiple bent sections. The connecting rod is rotatably connected to the bent sections. The bending directions of two adjacent bent sections are opposite.

[0010] Furthermore, the number of extrusion blocks is three, and the drive rod includes a first bending segment, a second bending segment, and a third bending segment. The second bending segment is located between the first bending segment and the third bending segment, and the bending direction of the second bending segment is opposite to that of the first bending segment and the third bending segment.

[0011] Furthermore, the mixing tank includes a lid and a stirring device. The lid is installed at the upper opening of the tank body, and the stirring device includes a first motor and a stirring rod. The first motor is installed on the lid and drives the stirring rod to rotate. The lid is provided with an air inlet.

[0012] Furthermore, the output device includes a pressure block, a top block, and a spring. The housing has an output cavity that communicates with the outer wall of the housing. The fourth channel communicates with the output cavity. The output tube is connected to the output cavity. The top block is located inside the output cavity. The spring is located between the pressure block and the top block. The top block can slide along the output cavity. The pressure block is threadedly connected to the housing. The top block can close the connection end between the fourth channel and the output cavity.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model homogenizes the grease in the extrusion chamber by reciprocating extrusion of the extrusion block. The extrusion device is equipped with a drive rod with multiple bending sections, which can drive multiple extrusion blocks to slide and extrude during rotation. Furthermore, adjacent extrusion blocks can intermittently extrude the grease through two adjacent bending sections with different orientations, making the grease more homogenized and achieving better results.

[0015] 2. The two channels of the same extrusion chamber are located at different positions to realize the process of material discharge when the extrusion block is extruding and material feeding when the extrusion block returns. This realizes the extrusion and conveying of grease while extruding and homogenizing the grease, which is convenient for homogenizing a small amount of grease for testing.

[0021] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] like Figures 1-4As shown, a grease homogenizer includes a mixing tank 1, a homogenizing device 2, and an output device 3. The mixing tank 1 includes a tank body 11, a feed pipe 111, a tank cover 12, and a mixing device 13. The feed pipe 111 is located at the lower end of the tank body 11, and the tank cover 12 is installed at the upper opening of the tank body 11. The mixing device 13 includes a first motor 131 and a mixing rod 132. The first motor 131 is installed on the tank cover 12 and drives the mixing rod 132 to rotate. The device can stir the grease material entering the barrel 11, making the grease output from the feed pipe 111 smoother. The barrel cover 12 is provided with an air inlet 121. By inflating the top of the barrel 11, the grease in the barrel 11 is squeezed towards the feed pipe 111. The feed pipe 111 connects the barrel 11 and the homogenizing device 2. The feed pipe 111 is equipped with a solenoid valve 112. The solenoid valve 112 is closed when the barrel 11 is fed and opened when the barrel 11 is discharged.

[0023] The homogenizing device 2 includes a housing 21 and an extrusion device 22. The housing 21 includes multiple extrusion chambers 211. The extrusion device 22 includes a second motor 221, a drive rod 222, multiple extrusion blocks 23, and a guide seat 25. The extrusion blocks 23 are at least partially located within the extrusion chambers 211 and can slide along the extrusion chambers 211. The second motor 221 drives the drive rod 222 to rotate. The drive rod 222 and the extrusion blocks 23 are connected by a connecting rod 24. The two ends of the connecting rod 24 are rotatably connected to the drive rod 222 and the extrusion blocks 23, respectively. The axial direction of the drive rod 222 is perpendicular to the axial direction of the extrusion blocks 23. The drive rod 222 has multiple bent sections. The connecting rod 24 is rotatably connected to the bent sections. The bending directions of two adjacent bent sections are opposite. When the drive rod 222 rotates, it can drive the extrusion blocks 23 to slide along the extrusion chambers 211 through the crank connection structure of the connecting rod 24, thus enabling the extrusion of the extrusion blocks 23 within the extrusion chambers 211 to be extruded. The grease is homogenized by reciprocating compression and pounding. For example, in this embodiment, there are three compression blocks 23 and three compression chambers 211. The drive rod 222 includes a first bending section 2221, a second bending section 2222, and a third bending section 2223. The second bending section 2222 is located between the first bending section 2221 and the third bending section 2223. The bending direction of the second bending section 2222 is opposite to that of the first bending section 2221 and the third bending section 2223. When the compression block 23 connected to the second bending section 2222 approaches the closed end of the compression chamber 211, the compression block 23 connected to the first bending section 2221 and the third bending section 2223 moves away from the closed end of the compression chamber 211, so that the two adjacent compression blocks 23 are squeezed and homogenized in an alternating manner. The guide seat 25 is provided with multiple guide sleeves 251. The guide sleeves 251 are slidably connected to the compression blocks 23, so that the movement of the compression blocks 23 is more stable.

[0024] The housing 21 is provided with a first channel 212, a second channel 213, and a third channel 214. The connection ends of the first channel 212, the second channel 213, and the third channel 214 with the extrusion chamber 211 are located at the end away from the opening of the extrusion chamber 211. The first channel 212 connects the feed pipe 111 and the first extrusion chamber 211. The second channel 213 connects two adjacent extrusion chambers 211. The third channel 214 connects the last extrusion chamber 211 and the output device 3. The first channel 212, the second channel 213, and the third channel 214 are used to transport grease. The second channel 213 is closer to the closed end of the extrusion chamber 211 than the first channel 212, so that the extrusion block 23 connecting the first bent section 2221 is closer to the extrusion chamber 211. When the grease is close to the closed end of the compression chamber 211, the first channel 212 will be closed by the compression block 23 earlier than the second channel 213. The compressed grease flows from the second channel 213 to the next compression chamber 211. One of the two second channels 213 connecting the same compression chamber 211 is closer to the closed end of the compression chamber 211. That is, the second channel 213 connecting the next compression chamber 211 is closer to the closed end of the compression chamber 211, so that the grease in the adjacent two compression chambers 211 can be transferred backward. The third channel 214 is closer to the closed end of the compression chamber 211 than the second channel 213, so that the grease in the last compression chamber 211 is sent out to the outside of the housing 21 through the third channel 214.

[0025] The extrusion block 23 is provided with an extrusion groove 231. The side wall of the end of the extrusion block 23 facing the closed end of the extrusion chamber 211 is provided with a conical surface. The diameter of the part of the extrusion block 23 with the conical surface gradually decreases towards the closed end of the extrusion chamber 211. The inner wall of the extrusion chamber 211 is provided with a conical surface corresponding to the conical surface of the extrusion block 23. The grease in the extrusion chamber 211 is squeezed by the extrusion block 23 and squeezed out along the conical surface towards the larger diameter end. The second channel 213 or the third channel 214 is located facing the larger diameter end and can allow the grease to enter. The extrusion groove 231 is located on the side wall of the end of the extrusion block 23 facing the closed end of the extrusion chamber 211. The extrusion groove 231 connects the end face of the extrusion block 23 facing the closed end of the extrusion chamber 211 and the second channel 213 or the third channel 214. The extrusion groove 231 can concentrate the grease squeezed by the two inclined surfaces and squeeze it into the second channel 213 or the third channel 214 for backward transmission.

[0026] The output device 3 includes a housing 31, a pressure block 32, a top block 33, and a spring 34. The housing 31 has an output pipe 311, a fourth channel 312, and an output cavity 313. The output cavity 313 is connected to the outer wall of the housing 31, and the fourth channel 312 is connected to the output cavity 313. The output pipe 311 is connected to the output cavity 313. The top block 33 is located inside the output cavity 313. The spring 34 is located between the pressure block 32 and the top block 33. The top block 33 can slide along the output cavity 313. The pressure block 32 is threadedly connected to the housing 31. The pressure block 32 can be adjusted by rotating the pressure block 32. The compression degree of spring 34 is adjusted, thereby adjusting the pressure of top block 33. Top block 33 can seal the connection end between fourth channel 312 and output chamber 313. When the squeezing block 23 in the last position squeezes the grease, the grease pressure in fourth channel 312 is greater than the elastic force of spring 34, which will push the top block 33 up. Fourth channel 312 is connected to output chamber 313, and grease is output from output pipe 311. When squeezing block 23 in the last position moves away from the closed end of squeezing chamber 211, spring 34 resets and seals fourth channel 312 to prevent grease from being sucked back.
