Description

Technical Field

[0001] The utility model relates to the field of boron carbide processing, and more specifically, to a filter press device for purifying boron carbide raw materials. Background Art

[0002] Filter press equipment for purifying boron carbide raw materials refers to equipment used in the boron carbide production process to purify the raw materials by filtration. The hydraulic cylinder of the filter press is activated, causing the piston rod of the hydraulic cylinder to extend and drive multiple filter frames to fit together. The raw materials for boron carbide production are then passed into the plate and frame filter press. The slurry of boron carbide raw materials to be processed is fed into the filter chamber through the filter press feed port. The filter chamber is composed of a series of alternating filter plates and filter frames, each of which is covered with filter cloth. After feeding, the slurry flows into the filter chamber under the action of pressure. Due to the action of the filter cloth, solid particles are retained on the filter cloth, forming a filter cake, while the liquid portion flows out through the filter cloth and is collected in the filtrate tank. When the filtration process is complete, the piston rod of the hydraulic cylinder retracts and no longer squeezes the filter frames. The filter frames are driven by the pulling device to separate one by one, and the filter cake falls out of the filter chamber, thus achieving the purification of the boron carbide raw materials.

[0003] When using common filter press equipment for purifying boron carbide raw materials, after a long period of use, the cylinder body of the hydraulic cylinder is affected by the friction between its internal piston and sealing ring, which will cause the cylinder body of the hydraulic cylinder and the hydraulic oil in the cylinder body to generate heat. This type of heat is usually dissipated naturally. After long-term use, the hydraulic oil in the hydraulic cylinder is easily affected by the heat, causing its own lubrication performance to decline, making the sealing ring prone to excessive wear. The sealing ring is easily aged after being affected by heat, affecting its own sealing performance, affecting the normal operation of the hydraulic cylinder, and thus affecting the normal use of the filter press. Therefore, we proposed a filter press equipment for purifying boron carbide raw materials to solve the above problems. Utility Model Content

It is equipped with an air intake fan and a heat dissipation sleeve. The heat dissipation sleeve is mounted on the cylinder body of the hydraulic cylinder. The heat generated inside the cylinder body is transferred to the heat dissipation sleeve. The operation of the air intake fan causes the air flow to flow through the heat dissipation sleeve to dissipate heat to the heat dissipation sleeve, thereby dissipating heat to the hydraulic cylinder body and the hydraulic oil inside the cylinder body, ensuring the lubricating performance of the hydraulic oil, preventing aging and excessive wear of the sealing ring, and making the operation of the hydraulic cylinder more stable, thereby ensuring the normal operation of the filter press body.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the advantages of the present invention are:

[0017] (1) This solution, through the arrangement of the air intake fan and the heat dissipation sleeve, is placed on the cylinder body of the hydraulic oil cylinder. The heat generated inside the cylinder body is transferred to the heat dissipation sleeve. The operation of the air intake fan causes the air flow to flow through the heat dissipation sleeve, thereby dissipating the heat of the heat dissipation sleeve, thereby dissipating the heat of the hydraulic oil cylinder body and the hydraulic oil inside the cylinder body, ensuring the lubricating performance of the hydraulic oil, preventing the aging and excessive wear of the sealing ring, and making the operation of the hydraulic oil cylinder more stable, thereby ensuring the normal operation of the filter press body;

[0018] (2) In this solution, by setting up the bent guide plate and the side guide plate, when the airflow passes through the heat dissipation groove 1 of the heat dissipation sleeve, the airflow is forced to pass through the side of the inner wall of the heat dissipation groove 1 under the guidance of the bent guide plate, thereby improving the heat dissipation capacity of the heat dissipation groove 1. When the airflow passes through the heat dissipation groove 2, the flow rate of the airflow passing through the heat dissipation groove 2 is increased under the separation of the side guide plate and the action of the guide surface on the side guide plate, thereby improving the heat dissipation capacity of the heat dissipation groove 2, thereby further improving the heat dissipation capacity of the heat dissipation sleeve for the hydraulic cylinder.

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the specification of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0027] See also Figure 1-Figure 5A filter press device for purifying boron carbide raw materials includes a filter press body 1 and a hydraulic cylinder 2 fixed to the side of the filter press body 1. The cylinder body of the hydraulic cylinder 2 is respectively sleeved with a heat dissipation sleeve 7 and an air outlet cover 6. The heat dissipation sleeve 7 is made of metal aluminum or metal copper and has high thermal conductivity, thereby improving the heat dissipation capacity of the heat dissipation sleeve 7 itself. The heat dissipation sleeve 7 is respectively provided with a plurality of heat dissipation slots 71 and a plurality of heat dissipation slots 72 distributed at intervals. The heat dissipation slots 71 and the heat dissipation slots 72 are both connected to the air outlet of the air outlet cover 6. An air guide shell 3 is fixed to the air outlet cover 6. The air guide shell 3 is connected to the air outlet cover 6, and the air guide shell 3 is connected to the air outlet cover 6 through a support. The frame is fixed on the filter press body 1, the air inlet fan 4 is fixed on the inner wall of the air guide shell 3, and a perforated plate 5 is fixed at the air inlet of the air inlet fan 4 on the top of the air guide shell 3. The outer cover 14 is sleeved on the heat dissipation sleeve 7. When the air inlet fan 4 is running, the air flow enters the air outlet cover 6 from the air guide shell 3, and then enters the heat dissipation groove 1 71 and the heat dissipation groove 2 72 of the heat dissipation sleeve 7 from the air outlet cover 6, thereby realizing heat dissipation of the heat dissipation sleeve 7, heat dissipation of the cylinder body of the hydraulic cylinder 2 and the hydraulic oil inside the cylinder body, ensuring the lubricating performance of the hydraulic oil, preventing aging and excessive wear of the sealing ring, and making the operation of the hydraulic cylinder 2 more stable, thereby ensuring the normal operation of the filter press body 1.

[0028] like Figure 3 and Figure 4 As shown, in this embodiment, the side of the inner wall of the heat dissipation slot 71 is inclined, the opening distance of the heat dissipation slot 71 close to the air outlet cover 6 is smaller than the opening distance of the heat dissipation slot 71 away from the air outlet cover 6, and a bent guide plate 8 is fixed on the side of the inner wall of the heat dissipation slot 71 close to the hydraulic cylinder 2. The bending part of the bent guide plate 8 is a curved surface 9. When the air flows through the heat dissipation slot 71, since the opening distance of the heat dissipation slot 71 close to the air outlet cover 6 is smaller than the opening distance of the heat dissipation slot 71 away from the air outlet cover 6, the air flow is directed to the heat dissipation slot 71. The opening distance on the side, when the air flow flows directly through the heat dissipation slot 71, the air flow enters the heat dissipation slot 71 from the small opening and flows out from the large opening, and it is difficult to flow along the inner wall of the heat dissipation slot 71, so it is difficult to achieve better heat dissipation of the heat dissipation slot 71. A curved guide plate 8 is fixed in the heat dissipation slot 71. When the air flow passes through the heat dissipation slot 71, the curved guide plate 8 guides the air flow to force it to pass through the side of the inner wall of the heat dissipation slot 71, thereby improving the heat dissipation capacity of the heat dissipation slot 71.

[0029] like Figure 3 and Figure 4 As shown, in this embodiment, two through holes 10 are opened on the curved surface 9 of the curved guide plate 8. The through holes 10 are used for air flow to pass through the inside of the curved guide plate 8 to achieve heat dissipation on the inner wall of the curved guide plate 8, thereby improving the heat dissipation capacity of the curved guide plate 8.

[0030] like Figure 3 and Figure 4As shown, in this embodiment, a partition plate 11 is fixed to the inner wall of the bent guide plate 8, and the partition plate 11 is located between the two through holes 10. When the airflow enters the partition plate 11 fixed inside the bent guide plate 8 from the through hole 10 on the curved surface 9 of the bent guide plate 8, the airflow passing through is diverted by the partition plate 11, and the contact area between the bent guide plate 8 and the airflow is increased by the partition plate 11, thereby improving the heat dissipation capacity of the bent guide plate 8, thereby further improving the heat dissipation capacity at the heat dissipation slot 71.

[0031] like Figure 3 and Figure 4 As shown, in this embodiment, the side surface of the inner wall of the heat dissipation slot 2 72 is inclined, and the opening distance of the heat dissipation slot 2 72 on the side close to the air outlet hood 6 is greater than the opening distance of the heat dissipation slot 2 72 on the side away from the air outlet hood 6. Since the opening distance of the heat dissipation slot 2 72 on the side close to the air outlet hood 6 is greater than the opening distance of the heat dissipation slot 2 72 on the side away from the air outlet hood 6, when the air flow flows through the heat dissipation slot 2 72, under the action of the shape of the inner wall of the heat dissipation slot 2 72, the air flow passes through the inner wall of the heat dissipation slot 2 72, thereby achieving heat dissipation at the heat dissipation slot 2 72 and improving the heat dissipation capacity of the heat dissipation slot 2 72.

[0032] like Figure 3 and Figure 4 As shown, in this embodiment, a side guide plate 12 is fixed to the side of the inner wall of the heat dissipation groove 2 72 , and the side guide plate 12 is used to increase the contact area between the inner wall of the heat dissipation groove 2 72 and the airflow, thereby improving the heat dissipation capacity at the heat dissipation groove 2 72 through the side guide plate 12 .

[0033] like Figure 5 As shown, in this embodiment, the side of the side guide plate 12 close to the hydraulic cylinder 2 is an inclined guide surface 13. When the airflow passes through the bottom of the side guide plate 12, the flow velocity of the airflow can be increased under the action of the inclined guide surface 13 at its bottom, thereby improving the heat dissipation capacity of the side guide plate 12 at the heat dissipation groove 2 72.

[0034] Working principle: The heat dissipation sleeve 7 is sleeved on the cylinder body of the hydraulic oil cylinder 2. The heat generated inside the cylinder body during operation is transferred to the heat dissipation sleeve 7. The air intake fan 4 operates to make the air flow enter from the orifice plate 5, pass through the air guide housing 3, and then enter the air outlet cover 6. Then, the air flows from the air outlet cover 6 to the heat dissipation groove 1 71 and the heat dissipation groove 2 72 of the heat dissipation sleeve 7, and finally flows out from the end of the heat dissipation sleeve 7, thereby realizing the heat dissipation of the cylinder body of the hydraulic oil cylinder 2 and the hydraulic oil inside the cylinder body, ensuring the lubricating performance of the hydraulic oil, preventing the aging and excessive wear of the sealing ring, making the operation of the hydraulic oil cylinder 2 more stable, thereby ensuring the normal operation of the filter press body 1;

[0035] When the air flows through the heat dissipation slot 71, since the opening distance of the heat dissipation slot 71 close to the air outlet cover 6 is smaller than the opening distance of the heat dissipation slot 71 away from the air outlet cover 6, when the air flows directly through the heat dissipation slot 71, the air flows into the heat dissipation slot 71 from the small opening and flows out from the large opening, and it is difficult to flow along the inner wall of the heat dissipation slot 71, thereby making it difficult to achieve good heat dissipation at the heat dissipation slot 71. A bent guide plate 8 is fixed in the heat dissipation slot 71. When the air flows through the heat dissipation slot 71, the air flows into the heat dissipation slot 71 from the small opening and flows out from the large opening. When passing through, the airflow is forced to pass through the side of the inner wall of the heat dissipation groove 71 under the guiding effect of the curved guide plate 8, thereby improving the heat dissipation capacity of the heat dissipation groove 71. At the same time, part of the airflow enters the partition plate 11 fixed inside the curved guide plate 8 from the through hole 10 on the curved surface 9 of the curved guide plate 8. The partition plate 11 divides the airflow passing through and dissipates the heat of the curved guide plate 8 from the inner wall of the curved guide plate 8, thereby further improving the heat dissipation capacity of the heat dissipation groove 71.

[0036] When the air flow passes through the heat dissipation slot 2 72 , since the opening distance of the heat dissipation slot 2 72 on the side close to the air outlet hood 6 is greater than the opening distance of the heat dissipation slot 2 72 on the side away from the air outlet hood 6 , when the air flow passes through the heat dissipation slot 2 72 , under the action of the shape of the inner wall of the heat dissipation slot 2 72 , the air flow passes through the inner wall of the heat dissipation slot 2 72 , thereby achieving heat dissipation at the heat dissipation slot 2 72 , and when the air flow passes through the heat dissipation slot 2 72 , under the action of the guide surface 13 at the bottom of the side guide plate 12 , the speed of the air flow passing through the bottom of the side guide plate 12 is increased, thereby further improving the heat dissipation capacity of the heat dissipation slot 2 72 , and through the cooperation between the heat dissipation slot 1 71 and the bent guide plate 8 and the heat dissipation slot 2 72 and the side guide plate 12 , the heat dissipation capacity of the heat dissipation sleeve 7 is further improved, thereby further improving the heat dissipation capacity of the hydraulic cylinder 2.

Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
