Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sesame paste production equipment, in particular to a sesame paste grinding millstone and a grinding device containing the same. BACKGROUND

[0002] The traditional production method of sesame paste is to first roast and then grind into sesame paste through a stone mill.

[0003] The stone mill used for the sesame paste produced by the traditional method is driven to rotate by a motor as a power source, but the rotating speed has an upper limit. Because the stone mill millstone rotating speed is too high, the temperature is generated, and the cold grinding production is required for the sesame paste production, and the high temperature will destroy the nutritional ingredients in the sesame and affect the flavor. More importantly, the high temperature will cause the oil oxidation and rancidity of the sesame paste.

[0004] Therefore, in order to ensure that the sesame paste can maintain good quality, the speed of the stone mill is generally limited in the sesame paste grinding equipment produced by the traditional method, so as to control the temperature of the stone mill.

[0005] The way of water cooling is used to cool the stone mill to improve the rotating speed of the stone mill, which is a thought to improve the production efficiency. However, similarly, this is also an industry problem:

[0006] 1. The internal waterway processing of the stone mill is not good, and how to ensure the internal waterway processing of the stone mill and the strength of the stone mill itself is a problem;

[0007] 2. The sealing property of the waterway needs to be ensured, and the water cannot be in contact with the sesame paste and sesame to affect the product quality;

[0008] 3. Since the stone mill needs to be kept rotating, the waterway needs to be kept circulating water, and how to provide stable cooling water on the basis of ensuring the above two points. SUMMARY

DETAILED DESCRIPTION

[0059] The following description is made in conjunction with the accompanying drawings Figures 1-8 The application is further described in detail.

[0060] The application discloses a sesame paste grinding device, which comprises a sesame paste grinding millstone, which is described below in the same embodiment.

[0061] Reference Figure 1 The sesame paste grinding device comprises a stone mill body 1, a top frame 3, a top shell 4, a water channel shell 2, and a lower mill body 7. The lower mill body 7 and the stone mill body 1 are both made of stone, and are both made of marble in this embodiment. The lower mill body 7 is horizontally installed on a device base, and the stone mill body 1 is placed on the lower mill body 7 and rotationally connected with the lower mill body 7. The central axes of the stone mill body 1 and the lower mill body 7 are collinear, and the rotation axis of the stone mill body 1 is collinear with the central axis thereof. The radii of the lower mill body 7 and the stone mill body 1 are the same.

[0062] In combination Figure 2 and Figure 3The lower surface edge portion of the lower grinding body 7 is provided with a grinding line 11. A motor for driving the rotation of the stone grinding body 1 is installed at the bottom of the lower grinding body 7, and the rotating shaft of the motor penetrates the lower grinding body 7. A material channel 12 is provided at the bottom of the stone grinding body 1, and the material channel 12 is located at the inner edge of the grinding line 11. The material in the material channel 12 can move to the grinding line 11 area under the rotation of the stone grinding body 1, and then move outward from the grinding line 11 area. A discharging hole 13 is provided at the top of the stone grinding body 1 and communicates with the material channel 12. The circumferential outer wall of the lower grinding body 7 is fixedly provided with a material guiding ring 75, which is used to receive the sesame paste flowing out of the lower grinding body 7. One end of the material guiding ring 75 is provided with a discharging port, and the sesame paste on the material guiding ring 75 flows to the discharging port through the inclined arrangement of the material guiding ring 75.

[0063] The water channel shell 2 is attached to the edge portion of the upper surface of the stone grinding body 1, and the water channel shell 2 contains flowing water, which cools the stone grinding body 1 through the attachment relationship with the stone grinding body 1. The top frame 3 is located on the upper surface of the stone grinding body 1, and a fixing assembly 5 is arranged between the top frame 3 and the stone grinding body 1. The top frame 3 cannot rotate relative to the stone grinding body 1, and after being fixed, the top frame 3 can be used for hoisting the stone grinding body 1, and at the same time, the water channel shell 2 is fixed on the stone grinding body 1. The top shell 4 is installed on the top frame 3 to protect the top frame 3. A discharging cylinder 41 is installed on the top shell 4 opposite the discharging hole 13, the bottom end of the discharging cylinder 41 communicates with the discharging hole 13, and the top end of the discharging cylinder 41 is open and faces the center position of the stone grinding body 1. The end of the sesame conveying pipe is arranged above the center of the stone grinding body 1, and the discharging cylinder 41 is used to receive the sesame. The top shell 4 is provided with a plurality of lifting lugs for lifting.

[0064] Reference Figure 3 And Figure 4 A cooling groove 71 is provided at the position opposite to the grinding line 11 on the lower surface of the lower grinding body 7, and the depth of the cooling groove 71 is not more than 10 cm, and in this embodiment, the depth is 6 cm. A sealing plate 72 is fixedly arranged at the bottom of the cooling groove 71 to close the cooling groove 71. The sealing plate 72 is communicated with a water supply pipe 73 and a return pipe 74. The water supply pipe 73 supplies water to the cooling groove 71 for cooling, and the water in the cooling groove 71 flows into the water tank through the return pipe 74. The thickness of the stone grinding body 1 is in the range of 25-40 cm, and in this embodiment, the thickness of the stone grinding body 1 is 32 cm, and the radius is 60 cm.

[0065] The motor drives the rotation of the stone grinding body 1, the sesame enters the material channel 12 through the discharging cylinder 41, and the sesame is ground under the rotation of the stone grinding body 1, and the ground sesame paste is received by the material guiding ring 75. The lower grinding body 7 can be cooled by supplying water to the cooling groove 71 provided at the bottom, and since it is only used to bear the pressure of the stone grinding body 1, the cooling groove 71 can be provided for cooling, and the cooling groove 71 is located at the bottom, so even if water leaks, it will not contaminate the sesame paste.

[0066] The stone grinding body 1 can be better cooled by opening a cooling groove 71 due to strength requirements, but if leakage occurs, it will contaminate the sesame paste, so the stone grinding body 1 cannot be grooved for direct water contact cooling. The stone grinding body 1 is thinned, and the water channel shell 2 attached to the stone grinding body 1 is used to assist cooling. On the one hand, the thinning of the stone grinding body 1 improves the heat dissipation efficiency of the stone grinding body 1, and on the other hand, the contact of the water channel shell 2 further dissipates heat, and the sealing structure of the water channel shell 2 greatly reduces the risk of water leakage caused by cracking of the stone grinding body 1. The top frame 3 is used to drive the stone grinding body 1 to rotate and hoist, on the one hand, and increase the weight of the stone grinding body 1, on the other hand, and can also fix and protect the water channel shell 2. In this way, not only is the effective cooling of the electric grinding disc realized, but also the highest rated speed of the electric grinding disc is improved to improve the production efficiency of the sesame paste; in addition, the replacement cost of the stone grinding body 1 as the most easily replaced consumable is also effectively reduced.

[0067] Reference Figure 2 and Figure 5 The water channel shell 2 includes a water channel ring shell 21, a water channel ring plate 22, and a partition plate 23. The water channel ring shell 21 is in the shape of a circular ring. The upper surface of the stone grinding body 1 is polished and coated with a heat-conducting layer, and the bottom of the water channel ring shell 21 is in close contact with the heat-conducting layer. The heat-conducting layer is a heat-conducting silicone grease.

[0068] The water channel ring plate 22 is one, which is fixed in the water channel ring shell 21, and divides the water channel ring shell 21 into two annular water cavities 211. The two separation plates 23 are a group, and each annular water cavity 211 is provided with a group of two separation plates 23, and the two separation plates 23 in each group are distributed at equal distances along the central axis of the water channel ring plate 22. The separation plate 23 is fixed between the water channel ring plate 22, and separates the annular water cavity 211 into two spaces. The separation plate 23 is inclined to the outside of the stone mill body 1 in the opposite direction of the rotation of the stone mill body 1, and among the two adjacent separation plates 23 in the adjacent water channel ring cavities, the separation plate 23 located in the inner water channel ring cavity is farther away from the rotation direction of the stone mill body 1. The water channel ring plate 22 is provided with a communication hole 221 between the two adjacent separation plates 23 in the two annular water cavities 211, that is, the communication hole 221 on the water channel ring plate 22 is two. The top of the upper surface of the water channel ring shell 21 is provided with two water inlet holes 212, which are close to the separation plate 23, and the water inlet hole 212 is communicated with the inner water channel ring cavity, and the spaces communicated by the two water inlet holes 212 are not communicated, and the water inlet hole 212 is used for water flowing into the water channel shell 2. The circumferential outer side wall of the water channel ring shell 21 is communicated with two water outlet pipes 213, and the position of the water outlet pipe 213 is adjacent to the separation plate 23 in the outer annular water cavity 211, and is located on the side of the separation plate 23 away from the rotation direction of the stone mill body 1. The water entering the water channel ring shell 21 from the water inlet hole 212 can flow along the rotation direction of the stone mill body 1 from the inner annular water channel 42, and flow into the outer annular water channel 42 through the communication hole 221, and then flow out from the water outlet pipe 213 along the rotation direction of the stone mill body 1.

[0069] The lower mill body 7 is also provided with a water collecting ring channel 8, which is located outside the material guiding ring channel 75 and below the water outlet pipe 213 to collect the water flowing out of the water outlet pipe 213. The bottom of the water collecting ring channel 8 is communicated with the water tank.

[0070] The top shell 4 is provided with an annular water channel 42, which is provided with an opening and is communicated with a drainage pipe 421 at the bottom. The number of the drainage pipe 421 is the same as that of the water inlet hole 212, and after penetrating through the top shell 4, the drainage pipe 212 is communicated with the water channel shell 2 through the water inlet hole 212. The central axes of the annular water channel 42, the top shell 4 and the stone mill body 1 are collinear, and the lower material cylinder 41 is located inside the annular water channel 42. The annular water channel 42 is provided with a water pipe above for supplying water to the annular water channel 42, and the annular water channel 42 is used for collecting the water discharged by the water pipe. The bottom end of the water pipe is also provided with a splash-proof cover, which is also located in the annular water channel 42 and does not affect the normal rotation of the annular water channel 42.

[0071] During the rotation of the grinding stone body 1, water flows from the water pipe into the annular water channel 42, and then flows into the water channel shell 2 through the diversion pipe 421. The annular water channel 42 allows water to be added to the water channel shell 2 during the rotation of the grinding stone body 1 without interfering with the feed cylinder 41. The splash guard also effectively reduces water splashing. The water in the water channel shell 2 flows under the rotation of the grinding stone body 1 and flows through the connecting hole 221 into the outer annular water cavity 211, and then flows out through the water outlet pipe 213. The flow of water in the water channel shell 2 exchanges heat with the upper surface of the grinding stone body 1, thereby cooling the grinding stone body 1. The positions of the partition plate 23, the water outlet plate, and the connecting hole 221 cleverly utilize the structure of the annular water cavity 211 to form two non-connected water channels, making full use of the contact area between the water channel shell 2 and the grinding stone body 1. Since the bottom of the water channel shell 2 only contacts the millstone body 1, the water in the water channel shell 2 only needs to cover the bottom. Therefore, this water supply method prevents the water channel shell 2 from filling with water, reducing the pressure on the water channel shell 2. The rotation of the millstone body 1 also effectively increases the outflow of water from the water channel shell 2. The water flowing out from the outlet pipe 213 is collected by the water collection ring channel 8 and then flows into the water tank, reducing the probability of the cooling water coming into contact with the sesame paste.

[0072] refer to Figure 6 and Figure 7 The top frame 3 includes a main frame plate 31 and an embedded plate 32. A drive hole 15 is provided in the middle of the grinding stone body 1, through which the rotating shaft of the motor that drives the grinding stone body 1 passes. There are multiple main frame plates 31, six in this embodiment, equidistantly distributed in a circle with the central axis of the grinding stone body 1 as the center, and the multiple main frame plates 31 are fixed to each other. A water channel groove 311 for embedding the water channel shell 2 is provided at the bottom of the main frame plate 31. Multiple embedding slots 14 are provided on the upper surface of the grinding stone body 1, and the embedded plate 32 is located within the embedding slots 14. The embedded plate 32 is located below the water channel shell 2, with its ends not directly below the water channel shell 2. A first support plate 321 is fixed to the upper surface of the embedded plate 32 away from the drive hole 15, and a second support plate 322 is fixed to the upper surface of the embedded plate 32 near the drive hole 15. Both the first support plate 321 and the second support plate 322 are arc plates, with both ends abutting against the sidewalls of the adjacent main frame plate 31. Both the first support plate 321 and the second support plate 322 are fixed with a plurality of ribs 3211 that are fixed to the embedded plate 32. A reinforcing plate 315 is fixed between the main frame plates 31.

[0073] refer to Figure 7 and Figure 8The fixed assembly 5 comprises an arc shell 51 and an insertion plate 52. An inner ring groove 16 is formed on the bottom of the circumferential inner wall of the driving hole 15. Three main frame plates 31 are provided with insertion holes 312 at the end of the driving hole 15. The three main frame plates 31 with the insertion holes 312 are separated by one main frame plate 31. The insertion plate 52 is inserted into the insertion hole 312, and the bottom end of the insertion plate 52 penetrates the driving hole 15 and is inserted into the inner ring groove 16. An outer ring groove 17 is formed on the bottom of the circumferential outer wall of the stone mill body 1. The arc shell 51 is provided with two arc shells 51, and the bottom of the arc shell 51 abuts against the outer ring groove 17. The part of the arc shell 51 opposite to the end of the main frame is inserted with a bolt screwed with the end of the main frame plate 31, and the bolt is fastened with the main frame plate 31. The end of the main frame plate 31 protrudes from the area directly above the stone mill body 1, so that the arc shell 51 can abut against the bottom of the main frame plate 31. One arc shell 51 is installed on three adjacent main frame plates 31, and the water outlet pipe 213 protrudes from between the two arc shells 51. A plurality of rib plates 511 are fixedly arranged on the outer side wall of the arc shell 51 to strengthen the strength of the arc shell 51. The main frame plate 31 is fixedly provided with a main lifting lug 313, and the main lifting lug 313 can protrude from the top shell 4.

[0074] The driving body 6 is inserted into the driving hole 15 and is fixed with the driving body 6. The driving body 6 cannot rotate relative to the rotating shaft of the motor. The driving body 6 is fastened with the rotating shaft of the motor by a bolt. The driving body 6 is located in the driving hole 15 and abuts against the side wall of the plurality of insertion plates 52, so that the insertion plate 52 cannot be taken out from the inner ring groove 16. The upper surface of the main frame plate 31 without the insertion hole 312 is provided with a driving groove 314. The driving body 6 is fixedly provided with three driving blocks 61, and the driving blocks 61 are located in the driving groove 314 to drive the top frame 3 to rotate. The main frame plate 31, the arc shell 51, the embedded plate 32, the first support plate 321, the second support plate 322, the reinforcing plate 315, the insertion plate 52, the driving body 6, and the driving block 61 are all made of metal, and the embodiment is iron.

[0075] The main frame plate 31 serves as the main frame structure of the millstone body 1, fixing and protecting the water channel shell 2, and also adding weight to the millstone body 1. The main frame plate 31 is secured to the outer wall of the millstone body 1 via the arc shell 51. The main frame plate 31 is secured to the inner wall of the millstone body 1 via the insertion plate 52. This allows for hoisting using the main lifting lug 313 and moving the millstone body 1 via the main frame plate 31, improving protection during movement. The installation of the arc shell 51 with multiple main frame plates 31 effectively increases the strength of the arc shell 51, and the rib plate 511 further enhances its strength. The abutment between the arc shell 51 and the bottom of the main frame plate 31 effectively improves the stability of the arc shell 51 installation. The insertion plate 52 also allows for locking and fixing of the insertion block using the drive body 6. The embedded plate 32, through the first support plate 321 and the second support plate 322, fixes the main frame plate 31 on the millstone body 1, allowing the drive block 61 to rotate the main frame plate 31 while simultaneously rotating the millstone body 1. The first support plate 321 and the second support plate 322 not only improve the structural strength of the main frame plate 31 but also enhance the protection of the water channel shell 2 on both sides.

[0076] The implementation principle of the sesame paste grinding device in this application embodiment is as follows: The upper and lower parts of the stone mill are cooled separately, thereby increasing the maximum rated speed of the stone mill and improving the production efficiency of sesame paste. The upper part of the stone mill is the mill body 1. Compared to the upper grinding disc of a traditional stone mill, the mill body 1 has a reduced thickness, and surface cooling is achieved through a water channel shell 2 on its upper surface. The addition of water to the water channel shell 2 during the rotation of the mill body 1 has almost no impact on the rotation of the mill body 1 or the feeding of sesame seeds. It also improves the water flow efficiency within the water channel shell 2 and reduces the probability of water leakage. After the mill body 1 is thickened, its strength and weight are increased by a main frame plate 31. The main frame plate 31 is fixed to the mill body 1 by an arc shell 51 and an insertion plate 52. The rotation of the mill body 1 is achieved by an embedded block, thus not only enabling the hoisting of the mill body 1 but also driving its rotation through a drive block 61. The grinding stone body 1, as the upper grinding disc, has a relatively high wear rate. The thickening of the grinding stone body 1 can effectively reduce the replacement cost of the grinding stone body 1.

[0077] The lower grinding body 7 is the lower part of the stone mill. It adopts a bottom groove design to form a cooling water channel inside, thereby achieving cooling of the lower grinding body 7. Since the cooling groove 71 of the lower grinding body 7 will not come into contact with the sesame paste even if water leaks, heat exchange can be carried out by direct contact between water and the stone mill, thus improving cooling efficiency.

[0078] The embodiments of the present application are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
