[0032] Example

[0033] The present application embodiment provides a colloid mill device 10, please refer to Figure 1 The colloid mill comprises a colloid mill housing 11 , a static grinding disc 12 , a dynamic grinding disc 14 , a driving mechanism 15 and a liquid flow pipe 16 .

[0034] The top of the colloid mill housing 11 is provided with a feed port, through which the material to be crushed (such as pigskin block liquid) can be fed into the colloid mill device 10, and an end cover 13 is detachably installed at the feed port for closing the feed port.

[0035] The static grinding disc 12 is fixed in the colloid mill housing 11 and is circumferentially arranged along the inner wall of the colloid mill housing 11. There is a gap between the outer surface of the dynamic grinding disc 14 and the outer surface of the static grinding disc 12 to form a grinding chamber 171, so that the material to be crushed can be crushed in the grinding chamber 171. The dynamic grinding disc 14 is provided with a mounting channel along its own centerline axis, and the bottom end of the mounting channel passes through the bottom end of the dynamic grinding disc 14. The inside of the dynamic grinding disc 14 has at least one first cooling channel 142.

[0036] The driving mechanism 15 includes a rotating shaft 151 and a driving assembly 152 for driving the rotating shaft 151 to rotate. The rotating shaft 151 is passed through the bottom of the colloid mill housing 11 and fixed to the installation channel. The driving assembly 152 is arranged on the side of the rotating shaft 151. The driving assembly 152 drives the rotating shaft 151 to rotate. The rotation of the rotating shaft 151 can drive the moving grinding disc 14 to rotate relative to the static grinding disc 12, and the material to be crushed can be crushed in the grinding chamber 171.

[0037] Exemplarily, the bottom of the colloid mill housing 11 has an annular limiting groove 111, and the bottom end of the movable grinding disc 14 is connected to an annular slider 143, which is slidably matched with the annular limiting groove 111. Since the annular slider 143 can block the rotating shaft 151, it is difficult for liquid to leak from the gap between the rotating shaft 151 and the bottom of the colloid mill housing 11.

[0038] The rotating shaft 151 has a through channel 1511 along its axial direction, and a liquid outlet 1511a communicating with the first cooling channel 142 is provided at the top of the through channel 1511. The liquid flow pipe 16 is configured to supply cooling liquid to the first cooling channel 142, and the liquid flow pipe 16 is rotatably sealed and connected to the through channel 1511. A gap is provided between the liquid flow pipe 16 and the inner wall of the through channel 1511 to form a drainage channel 164, and a drainage port 1516 communicating with the first cooling channel 142 and the drainage channel 164 is provided on the side wall of the rotating shaft 151, so that the cooling liquid in the first cooling channel 142 can be discharged to the drainage channel 164.

[0039] When the liquid flow tube 16 remains stationary, the rotating shaft 151 can also rotate relatively. In the process of supplying coolant into the first cooling channel 142 through the liquid outlet 1511a of the through channel 1511 through the liquid flow tube 16, the coolant is not easy to leak, and the coolant in the first cooling channel 142 can be discharged through the drain port 1516 through the drain channel 164. The liquid flow tube 16 is arranged in the through channel 1511 of the rotating shaft 151. In order to conveniently drive the rotating shaft 151 to rotate along its axis, in this embodiment, the driving assembly 152 is arranged on the side of the rotating shaft 151, which can not only realize the rotation of the rotating shaft 151, but also more conveniently supply coolant into the liquid flow tube 16.

[0040] In addition, since the liquid flow tube 16 is arranged in the through channel 1511 of the rotating shaft 151, and the rotating shaft 151 is arranged on the central axis of the movable grinding disc 14, the first cooling channel 142 can be distributed at various positions of the movable grinding disc 14, so that the movable grinding disc 14 can be cooled, thereby achieving a better cooling effect.

[0041] The first cooling channel 142 includes a first cooling section 1421 disposed at the upper portion of the movable grinding disc 14 and a plurality of second cooling sections 1422 disposed at the middle and lower portions of the movable grinding disc 14. The liquid flow pipe 16 is connected to the first cooling section 1421. The first cooling section 1421 is arranged in an S shape on a transverse plane (refer to Figure 3 ), each second cooling section 1422 is connected to the first cooling section 1421.

[0042] Since the first cooling section 1421 is arranged in an S-shape on the transverse plane, the upper portion of the movable grinding disc 14 can be fully cooled. The plurality of second cooling sections 1422 are arranged in the middle and lower portions of the movable grinding disc 14, so that the middle and lower portions of the movable grinding disc 14 can be cooled, thereby achieving a good cooling effect on the entire movable grinding disc 14.

[0043] Exemplarily, each second cooling segment 1422 is spirally arranged along the height direction of the movable grinding disc 14, and the plurality of second cooling segments 1422 are spaced apart from the center to the outside of the movable grinding disc 14. Each second cooling segment 1422 cools the movable grinding disc 14 along a circle of the movable grinding disc 14, and the plurality of second cooling segments 1422 can play a cooling role from the center to the outside, thereby achieving all-round cooling of the movable grinding disc 14.

[0044] Furthermore, the static grinding disc 12 is provided with a second cooling channel 121 and a cooling medium inlet 122, and the cooling medium inlet 122 is connected to the second cooling channel 121. The cooling medium can be supplied to the second cooling channel 121 through the cooling medium inlet 122, so as to cool the static grinding disc 12. By cooling both the static grinding disc 12 and the dynamic grinding disc 14, a better cooling effect is achieved to avoid the denaturation of the crushed material. Optionally, the second cooling channel 121 is spirally arranged along the circumference of the static grinding disc 12, so as to better cool the static grinding disc 12.

[0045] For further information, please refer to Figure 2 The outer wall of the liquid flow tube 16 is provided with a fixed seat 163, the inner wall of the through channel 1511 is connected with a rotating seat 1512, the fixed seat 163 is provided with an annular groove 1631, and the rotating seat 1512 is provided with an annular protrusion 1513, and the annular protrusion 1513 and the annular groove 1631 can be slidably matched and sealed.

[0046] The annular protrusion 1513 cooperates with the annular groove 1631, so that the liquid flow tube 16 can rotate relatively smoothly relative to the through channel 1511. Moreover, the annular protrusion 1513 is sealed with the annular groove 1631, so that during the rotation of the liquid flow tube 16, the coolant will not leak from the connection between the annular protrusion 1513 and the annular groove 1631. Exemplarily, a sealing ring 1632 is provided in the annular groove 1631, and the sealing state can be better maintained through the action of the sealing ring 1632, thereby better preventing the leakage of the coolant.

[0047] Exemplarily, the liquid flow tube 16 includes a first section 161 and a second section 162, the outer diameter of the first section 161 is smaller than the outer diameter of the second section 162, so that the first section 161 and the second section 162 form a step, and the fixing seat 163 is sleeved on the first section 161 and abuts against the second section 162. Since the first section 161 and the second section 162 form a step, when the fixing seat 163 is sleeved on the first section 161, it abuts against the second section 162, so the position of the fixing seat 163 in the liquid flow tube 16 is relatively fixed, and a good sealing state can be maintained during the rotation of the liquid flow tube 16.

[0048] Among them, the top of the first section 161 has a water outlet for discharging the coolant and supplying it to the first cooling section 1421. The drain port 1516 of the rotating shaft 151 is arranged corresponding to the second section 162. The coolant enters the drain channel 164 from the second cooling section 1422 through the drain port 1516. Among them, the lower end of the rotating shaft 151 is connected to the liquid flow tube 16 through a rotating bearing. The side of the rotating shaft 151 is also connected to a drain pipe 1517, which is connected to the through channel 1511, so that the coolant is discharged from the drain channel 164 through the drain pipe 1517.

[0049] Furthermore, the driving assembly 152 of this embodiment is arranged on the side of the rotating shaft 151, and the driving assembly 152 includes a driving motor 1521 and a second bevel gear 1522 coaxially connected to the driving shaft of the driving motor 1521, and the driving shaft of the driving motor 1521 is arranged horizontally. The outer wall of the rotating shaft 151 is fixedly sleeved with a first bevel gear 1514, and the second bevel gear 1522 can mesh with the first bevel gear 1514.

[0050] The operation of the driving motor 1521 causes the driving shaft to rotate in the lateral direction. The rotation of the driving shaft drives the second bevel gear 1522 to rotate. Since the second bevel gear 1522 is meshed with the first bevel gear 1514, it can drive the first bevel gear 1514 to rotate. The rotation of the first bevel gear 1514 drives the rotating shaft 151 to rotate. The rotation of the rotating shaft 151 drives the movable grinding disc 14 to rotate relative to the static grinding disc 12.

[0051] The colloid mill device 10 is provided with a bracket 18, the bracket 18 is arranged below the bottom of the colloid mill housing 11, and the rotating shaft 151 is rotatably supported on the bracket 18. Since the rotating shaft 151 is supported by the bracket 18 during the rotation process, the rotating shaft 151 is more stable during the rotation process. Exemplarily, the outer wall of the rotating shaft 151 is sleeved with a sliding member 1515, the sliding member 1515 has a sliding protrusion 1515a, the bracket 18 is provided with an annular sliding groove 181, the sliding protrusion 1515a is slidably matched with the annular sliding groove 181, and the annular sliding groove 181 can limit the sliding protrusion 1515a, so that the sliding protrusion 1515a is restricted to slide in the annular sliding groove 181, thereby realizing the stable rotation of the rotating shaft 151.

[0052] In summary, the colloid mill device 10 of the present application drives the rotating shaft 151 to rotate through the driving assembly 152, and the rotating shaft 151 is fixed in the installation channel of the moving grinding disc 14. The rotation of the rotating shaft 151 can drive the moving grinding disc 14 to rotate relative to the static grinding disc 12. There is a gap between the outer surface of the moving grinding disc 14 and the outer surface of the static grinding disc 12 to form a grinding chamber 171, and the material can be crushed in the grinding chamber 171. Moreover, the liquid flow tube 16 is rotatably sealed and connected to the through channel 1511 of the rotating shaft 151. When the liquid flow tube 16 remains stationary, the rotating shaft 151 can also rotate relatively. In the process of supplying coolant to the first cooling channel 142 through the liquid flow tube 16, the coolant is not easy to leak, and the coolant in the first cooling channel 142 is discharged through the drainage channel 164. Since the liquid flow pipe 16 is arranged in the through channel 1511 of the rotating shaft 151, and the rotating shaft 151 is arranged on the central axis of the movable grinding disc 14, the first cooling channel 142 can be distributed at various positions of the movable grinding disc 14, so that the movable grinding disc 14 can be cooled down; at the same time, the cooling medium can be supplied to the second cooling channel 121 through the cooling medium inlet 122, so as to cool down the static grinding disc 12. By cooling down both the static grinding disc 12 and the movable grinding disc 14, a better cooling effect can be achieved.

[0053] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
