Description

Technical Field

[0001] The utility model relates to the technical field of ink production equipment, in particular to a cooling device for an ink sand mill. Background Art

[0002] In the process of ink production, an ink sand mill is needed to evenly grind liquid raw materials to a certain fineness. The working principle of the existing ink sand mill is that the ink raw materials are sent into the grinding cylinder of the sand mill through a feeding pump, and then the main shaft and the grinding disc rotating at high speed in the grinding cylinder will stir the grinding medium, so that the grinding medium collides with the ink raw materials, and thus the ink raw material components are ground fine.

[0003] Since a large amount of heat will be generated due to the mutual friction of the ink, the grinding medium and the disc in the grinding cylinder, which affects the quality of the ink product. Therefore, on the wall of the grinding cylinder of the existing ink sand mill, there are cooling chambers, as well as structures such as a water inlet pipe and a water outlet connected to the cooling chamber to cool down the inside of the grinding cylinder.

[0004] At present, the cooling chambers of ink sand mills have two pipeline structures, namely annular and serpentine. Among them, the annular pipeline structure is easy to process, but the water flow retention time is short and the heat transfer efficiency is low; the serpentine pipeline structure has a long water flow retention time, but it is complex to process and not easy to clean. Therefore, there is an urgent need for a cooling pipeline that is easy to process and clean and can extend the water flow retention time. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cooling device for an ink sand mill, which has the effects of being easy to process and clean and being able to extend the water flow retention time.

The cylinder body and the cylinder cover are fixedly connected by bolts and nuts. An annular groove is formed at the open end of the cylinder body. One side of the cylinder cover is fixedly provided with an annular protrusion that blocks the opening of the annular groove. The annular groove and the annular protrusion together form the annular cavity. The long strip partition is fixed in the annular groove, and one end of some of the long strip partitions is fixedly in contact with the bottom of the annular groove, and one end of the other part of the long strip partitions is movably in contact with the end of the annular protrusion. The feed pipe and the discharge pipe are respectively located on the cylinder body and the cylinder cover. The water inlet pipe and the water outlet pipe are located on the cylinder body. The filter cylinder is fixed on one side of the cylinder cover close to the rotating shaft.

[0008] A further setting of the present utility model is as follows: The rotating assembly includes a motor fixed on the cabinet, a small pulley fixedly installed at the output end of the motor, a driven shaft rotatably installed on the cabinet, a large pulley fixedly installed on the driven shaft, and a belt sleeved on the small pulley and the large pulley. One end of the rotating shaft rotatably penetrates through the sealed end of the cylinder body and is fixedly connected to the driven shaft.

[0009] A further setting of the present utility model is as follows: A chassis is fixedly provided on the top of the cabinet. The small pulley, the large pulley and the belt are located in the chassis. The motor is fixed on one side of the chassis, and the output end penetrates into the interior of the chassis to be connected to the small pulley. The driven shaft rotatably penetrates through the other side of the chassis, and one end extending into the chassis is fixedly connected to the large pulley.

[0010] A further setting of the present utility model is as follows: A connecting cylinder surrounding the driven shaft is fixedly provided on the side wall of the chassis, and the connecting cylinder is fixedly connected to the sealed end of the cylinder body by screws. A circle of limiting protrusions is fixedly provided on the part of the driven shaft located outside the chassis, and both ends of the limiting protrusions are respectively in rotational contact with the side wall of the chassis and the end wall of the cylinder body.

[0011] A further setting of the present utility model is as follows: A circle of supporting protrusions is fixedly provided at the end of the filter cylinder, and the rotating shaft rotatably inserts into the inner circle of the supporting protrusions.

[0012] A further setting of the present utility model is as follows: A plurality of card slots are evenly formed at the end of the annular protrusion, and the long strip partitions in contact therewith are inserted into the card slots.

[0013] A further setting of the present utility model is as follows: A plurality of connecting rods parallel to the rotating shaft are evenly arranged at the end of the annular protrusion, and each connecting rod is respectively inserted into the gap between adjacent long strip partitions. The end of the connecting rod away from the annular protrusion is close to the bottom of the annular groove, and a sector-shaped scraping plate parallel to and in contact with the bottom of the annular groove is fixedly provided. The sector-shaped scraping plate can slide in the gap between adjacent long strip partitions.

[0015] A further setting of the present utility model is that a pair of support seats are fixedly arranged at the bottom of the cylinder body, and the bottom of the support seats is fixedly connected to the top of the cabinet.

[0016] The beneficial effects of the present utility model are as follows: By adopting the above technical solution, when the sand mill processes ink, first, the water pump continuously injects cooling water into the water inlet pipe at the top of the cylinder body, so that the cooling water enters the annular cavity. Since the water inlet pipe is located between two adjacent long strip partitions in the annular cavity, the cooling water will first flow between the adjacent long strip partitions. Then, because one end of each pair of adjacent long strip partitions contacts both ends of the annular cavity respectively, and the other end leaves a gap between both ends of the annular cavity respectively, the cooling water will be divided into two paths and flow into the gaps between the other two pairs of adjacent long strip partitions alternately through the gaps left between the ends of the long strip partitions and the ends of the annular cavity. By analogy, each path of cooling water will flow back and forth in the annular cavity of the cylinder body, thereby increasing the residence time of the cooling water in the annular cavity. Finally, the cooling water divided into two paths will eventually converge in the bottom pair of adjacent long strip partitions and be discharged from the water outlet pipe between the pair of long strip partitions.

[0017] When the sand mill needs to clean the inside of the annular cavity, first, disassemble the bolts and screws between the cylinder cover and the cylinder body, and then pull the cylinder cover away from the cylinder body. Since the annular protrusion on the side of the cylinder cover is connected to the sector-shaped scraping plates between the gaps of each long strip partition through multiple connecting rods, during the process of the cylinder cover moving away from the cylinder body, the sector-shaped scraping plates in the gaps of each long strip partition will slide relative to the side walls of the long strip partitions, and at the same time scrape the fixed impurities deposited on both sides of the long strip partitions out of the annular groove, thereby achieving the effect of quickly cleaning the annular cavity. Among them, since all the long strip partitions in the annular cavity are parallel to each other and evenly surround the axis of the cylinder body, compared with the cooling cavity with a traditional serpentine pipeline structure, this structure is easier to process and manufacture.

Specific Embodiments

[0024] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Embodiment: An ink sand mill cooling device, as Figures 1-4 shown, includes a cabinet 1, a grinding cylinder 2 horizontally fixed on the top of the cabinet 1, a rotating shaft 3 rotating inside the grinding cylinder 2, a plurality of discs 4 evenly fixed on the rotating shaft 3, a rotating assembly 5 for driving the rotation of the rotating shaft 3, a feed pipe 6 and a discharge pipe 7 respectively fixedly arranged at both ends of the grinding cylinder 2 and communicating with its interior, a filter cylinder 8 fixed at the inner end of the grinding cylinder 2 and covering the connection between the discharge pipe 7 and the grinding cylinder 2, a plurality of filter holes 81 evenly opened on the side wall of the filter cylinder 8, and a cooling mechanism 9 is arranged on the side wall of the grinding cylinder 2. The cooling mechanism 9 includes an annular cavity 91 opened on the side wall of the grinding cylinder 2, a plurality of long strip partitions 92 evenly surrounding the axis of the grinding cylinder 2 and fixed in the annular cavity 91, a water inlet pipe 93 and a water outlet pipe 94 respectively fixed on the outer side wall of the grinding cylinder 2 and communicating with the interior of the annular cavity 91. The water inlet pipe 93 and the water outlet pipe 94 are symmetrically located on the upper and lower sides of the grinding cylinder 2 and are respectively located between adjacent long strip partitions 92. The length of the long strip partition 92 is less than the length of the annular cavity 91, and one ends of two adjacent long strip partitions 92 respectively contact both ends of the annular cavity 91, while the other ends respectively leave gaps with both ends of the annular cavity 91.

[0026] Furthermore, the grinding cylinder 2 includes a cylinder body 21 and a cylinder cover 22. The cylinder body 21 and the cylinder cover 22 are fixedly connected by bolts and nuts. An annular groove 911 is formed at the opening end of the cylinder body 21. An annular protrusion 912 for blocking the opening of the annular groove 911 is fixedly provided on one side of the cylinder cover 22. The annular groove 911 and the annular protrusion 912 together form an annular cavity 91. The long strip partition 92 is fixed in the annular groove 911, and one end of some of the long strip partitions 92 is fixedly in contact with the bottom of the annular groove 911, and one end of the other part of the long strip partitions 92 is movably in contact with the end of the annular protrusion 912. The feed pipe 6 and the discharge pipe 7 are respectively located on the cylinder body 21 and the cylinder cover 22. The water inlet pipe 93 and the water outlet pipe 94 are located on the cylinder body 21. The filter cylinder 8 is fixed on one side of the cylinder cover 22 close to the rotating shaft 3. By adopting the above structures of the cylinder cover 22 and the cylinder body 21, not only can the sand mill be conveniently disassembled and assembled, but also it is convenient for the staff to clean the inside of the annular cavity 91.

[0027] Furthermore, the rotating assembly 5 includes a motor 51 fixed on the cabinet 1, a small pulley 52 fixedly installed at the output end of the motor 51, a driven shaft 53 rotatably mounted on the cabinet 1, a large pulley 54 fixedly installed on the driven shaft 53, and a belt 55 sleeved on the small pulley 52 and the large pulley 54. One end of the rotating shaft 3 rotatably passes through the sealing end of the cylinder body 21 and is fixedly connected to the driven shaft 53. By adopting the above rotating assembly 5, not only can the rotating shaft 3 be effectively driven to rotate, but also the driving transmission structure of the large pulley 54 and the small pulley 52 can reduce the transmission speed of the motor 51 and increase the transmission torque of the motor 51 to ensure the stable rotation of the rotating shaft 3.

[0028] Furthermore, a chassis 10 is fixedly provided on the top of the cabinet 1. The small pulley 52, the large pulley 54 and the belt 55 are located in the chassis 10. The motor 51 is fixed on one side of the chassis 10, and its output end penetrates into the interior of the chassis 10 to connect with the small pulley 52. The driven shaft 53 rotatably passes through the other side of the chassis 10, and the end extending into the chassis 10 is fixedly connected to the large pulley 54. By adopting the above chassis 10, not only can the transmission safety and stability of the transmission structures such as the large pulley 54, the small pulley 52 and the belt 55 be ensured, but also it can prevent the staff from being injured by accidentally touching the high-speed rotating pulleys, the belt 55 and other components, thereby improving the use safety of the sand mill.

[0029] Further, a connecting cylinder 101 that surrounds the driven shaft 53 is fixedly arranged on the side wall of the chassis 10, and the connecting cylinder 101 is sealed at the end of the connecting cylinder 101 body 21 by screws. A limiting protrusion 531 is fixedly arranged on the part of the driven shaft 53 outside the chassis 10, and both ends of the limiting protrusion 531 are in rotational contact with the side wall of the chassis 10 and the end wall of the cylinder body 21 respectively; a supporting protrusion 82 is fixedly arranged at the end of the filter cylinder 8, and the rotating shaft 3 is rotatably inserted into the inner ring of the supporting protrusion 82. By adopting the above-mentioned connecting cylinder 101, limiting protrusion 531 and supporting protrusion 82, the rotation position of the rotating shaft 3 can be stably limited and supported, so as to ensure the stable and safe operation of the rotating shaft 3 and the disc 4.

[0030] Further, a plurality of card slots 912a are evenly arranged at the end of the annular protrusion 912, and the long strip partition 92 in contact with it is inserted into the card slots 912a. By adopting the above-mentioned card slots 912a, the sealing performance of the annular cavity 91 can be further improved to prevent the cooling water from leaking from the gap between the cylinder cover 22 and the cylinder body 21 to the inside and outside of the cylinder body 21.

[0031] Further, a plurality of connecting rods 912 parallel to the rotating shaft are evenly arranged at the end of the annular protrusion 912, and each connecting rod 912b is respectively inserted into the gap between adjacent long strip partitions 92. One end of the connecting rod 912b away from the annular protrusion 912 is close to the bottom of the annular groove 911, and a sector-shaped scraping plate 912c that is in parallel contact with the bottom of the annular groove 911 is fixedly arranged. The sector-shaped scraping plate 912c can slide in the gap between adjacent long strip partitions 92.

[0032] Further, a sector-shaped fitting groove 911a for inserting and fitting the sector-shaped scraping plate 912c is arranged at the bottom of the annular groove 911. By adopting the above-mentioned sector-shaped fitting groove 911a, the sector-shaped scraping plate 912c can be effectively placed to avoid the sector-shaped scraping plate 912c affecting the flow of the cooling water.

[0033] Further, a pair of support seats 211 are fixedly arranged at the bottom of the cylinder body 21, and the bottom of the support seats 211 is fixedly connected to the top of the cabinet 1. The water inlet pipe 93 and the water outlet pipe 94 are located in the middle of the cylinder body 21, and the water outlet pipe 94 is located between the two support seats 211. By adopting the above-mentioned support seats 211, the cylinder body 21 can be stably supported at a certain height to reserve a placement position for the water outlet pipe 94.

[0034] The working principle of this embodiment:

[0035] When the sand mill processes ink, first, the water pump continuously injects cooling water into the water inlet pipe 93 at the top of the cylinder body 21, so that the cooling water enters the annular cavity 91. Since the water inlet pipe 93 is located between two adjacent long strip partitions 92 in the annular cavity 91, the cooling water will first flow between the adjacent long strip partitions 92. Then, because one end of each pair of adjacent long strip partitions 92 contacts both ends of the annular cavity 91 respectively, and there are gaps between the other ends and both ends of the annular cavity 91 respectively, the cooling water will be divided into two paths and flow into the gaps between the other two pairs of adjacent long strip partitions 92 alternately through the gaps left between the ends of the long strip partitions 92 and the ends of the annular cavity 91. By analogy, each path of cooling water will flow back and forth in the annular cavity 91 of the cylinder body, thereby increasing the residence time of the cooling water in the annular cavity 91. Finally, the cooling water divided into two paths will eventually converge in the lowest pair of adjacent long strip partitions 92 and be discharged from the water outlet pipe 94 between the pair of long strip partitions 92.

[0036] When the sand mill needs to clean the inside of the annular cavity 91, first, disassemble the bolts and screws between the cylinder cover 22 and the cylinder body 21, and then pull the cylinder cover 22 away from the cylinder body 21. Since the annular protrusion 912 on the side of the cylinder cover 22 is connected to the sector-shaped scraping plates 912c between the gaps of each long strip partition 92 through multiple connecting rods 912c, during the process of the cylinder cover 22 moving away from the cylinder body 21, the sector-shaped scraping plates 912c in the gaps of each long strip partition 92 will slide relative to the side walls of the long strip partitions 92, and at the same time scrape the fixed impurities deposited on both sides of the long strip partitions 92 out of the annular groove 911, thereby achieving the effect of quickly cleaning the annular cavity 91. Among them, since all the long strip partitions 92 in the annular cavity 91 are parallel to each other and evenly surround the axis of the cylinder body 21, compared with the cooling cavity with a traditional serpentine pipeline structure, this structure is easier to process and manufacture.
