Description

Technical Field

[0001] This utility model relates to the technical field of vacuum suction filtration devices, and in particular to an energy-saving and efficient vacuum suction filtration device for yeast production. Background Technology

[0002] In the industrial production process of yeast, the fermentation broth needs to be concentrated by centrifugation first. At the same time, the yeast milk still contains a large amount of free water, which cannot be directly used for the processing of downstream products such as yeast paste and yeast strips. It is necessary to further reduce the moisture through a solid-liquid separation process. The vacuum drum filter is the core equipment of this solid-liquid separation process. The outer surface of the filter drum is covered with a special filter cloth, and the inside is connected to the vacuum system. When the filter drum rotates at a set speed and comes into contact with the yeast milk, the pressure difference formed inside and outside the filter drum will drive the liquid in the yeast milk to pass through the filter cloth and be drawn out, while the yeast solid particles are trapped by the filter cloth, gradually forming continuous and uniform yeast filter strips as the filter drum rotates.

[0003] Traditional vacuum filtration devices rely solely on vacuum negative pressure for dehydration, lacking mechanical pressing assistance. To achieve the desired dehydration effect, a high vacuum level must be maintained, resulting in high energy consumption of the vacuum system and limited filtration efficiency.

[0004] To address the aforementioned issues, a search revealed a patent with publication number CN218306504U that discloses a tubular vacuum filter. The patent states that "by setting several L-shaped tubular structures around the inside of the drum, the vacuum area inside the drum is reduced to between the vacuum holes in the tubular structures and the inner side of the drum. Compared to the full-cavity vacuum area in existing technologies, this saves a significant amount of energy while achieving a better vacuum effect, meeting the needs of starch filtration, and resulting in good economic benefits." However, this method only achieves energy saving by reducing the vacuum area, lacking the synergistic effect of mechanical pressing, and thus has limited improvement in overall dehydration efficiency.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0006] The purpose of this invention is to provide an energy-saving and efficient vacuum suction filtration device for yeast production, in order to solve the problems mentioned in the background art, that traditional vacuum suction filtration devices mostly rely solely on vacuum negative pressure for dehydration, lack mechanical pressing assistance, and require maintaining a high vacuum level to achieve the target dehydration effect, resulting in high energy consumption of the vacuum system and limited dehydration efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an energy-saving and efficient vacuum filtration device for yeast production, comprising a base, a bracket fixedly installed at the upper end of the base, a rotating shaft fixedly connected to both ends of the bracket, a first bevel gear sleeved on the outer ring of the rotating shaft, a fixing rod fixedly installed at the upper end of the base, a connecting rod fixedly connected to both ends of the fixing rod, a second bevel gear sleeved on the outer ring of the connecting rod, a connecting ring sleeved on the outer ring of the connecting rod, a slider fixedly installed at the front end of the connecting ring, a slide frame sleeved on the outer ring of the slider, a push rod fixedly installed at the front end of the slide frame, a limiting ring sleeved on the outer ring of the push rod, a pressing block fixedly installed at the front end of the push rod, and a first end cap sleeved on the outer ring of the rotating shaft.

[0008] Preferably, the first bevel gear and the second bevel gear are meshed together, and the fixed rod and the connecting rod form a rotating structure.

[0009] Preferably, a roller is fixedly installed at the rear end of the first end cap, and the outer wall of the pressing block is in close contact with the inner wall of the roller.

[0010] Preferably, the outer ring of the drum is fitted with a filter cloth, the outer ring of the filter cloth is fitted with a spiral heat absorption tube, and the upper end of the drum is provided with a feed inlet.

[0011] Preferably, water inlet pipes are fixedly installed through both ends of the first end cap, and steam pipes are fixedly installed through both ends of the first end cap.

[0012] Preferably, a second end cap is fixedly installed at the front end of the bracket, the front end of the second end cap is connected to the roller, and the rear end of the second end cap is fixedly connected to the limiting ring.

[0013] Preferably, a drive motor is provided at the upper end of the base, the output end of the drive motor is connected to a belt via a synchronous pulley, the belt is connected to a reducer via another set of synchronous pulleys, and the output end of the reducer is connected to the rotating shaft via a coupling.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The rotational motion of the rotating shaft is transmitted to the connecting rod through the meshing of the first and second bevel gears, causing the connecting rod to rotate synchronously. The rotation of the connecting rod drives the connecting ring to rotate, which in turn drives the slider to slide back and forth in the slide frame. This sliding is converted into the linear reciprocating motion of the push rod through the slide frame, which ultimately pushes the pressing block to move stably back and forth along the inner wall of the drum under the guidance and constraint of the limiting ring. The mechanical pressing force acts directly on the filter strip, actively squeezing out the interstitial water and some bound water in the filter strip, reducing the load of dehydration by vacuum negative pressure alone, and significantly reducing energy consumption.

[0016] 2. At the same time, this mechanical pressing can improve the filtration and dehydration efficiency. When the pressing block moves back and forth, it will continuously apply force to the filter strip, which can break up the tight surface layer of the filter strip, making it easier for water to seep out with less obstruction. At the same time, the continuous squeezing can also loosen the internal structure of the filter strip, giving the previously trapped water more room to flow and making it easier to drain. With the precise guidance of the push rod by the limiting ring, the movement trajectory of the pressing block is stable and can be evenly applied to the entire filter strip area, avoiding the problem of incomplete dehydration in some areas.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4This utility model provides a technical solution: an energy-saving and efficient vacuum filtration device for yeast production, including a base 1, a bracket 2 fixedly installed on the upper end of the base 1, a rotating shaft 3 fixedly connected to both ends of the bracket 2, a first bevel gear 4 sleeved on the outer ring of the rotating shaft 3, a fixing rod 5 fixedly installed on the upper end of the base 1, a connecting rod 6 fixedly connected to both ends of the fixing rod 5, a second bevel gear 7 sleeved on the outer ring of the connecting rod 6, a connecting ring 8 sleeved on the outer ring of the connecting rod 6, a slider 9 fixedly installed at the front end of the connecting ring 8, a slide frame 10 sleeved on the outer ring of the slider 9, a push rod 11 fixedly installed at the front end of the slide frame 10, a limiting ring 12 sleeved on the outer ring of the push rod 11, a pressing block 13 fixedly installed at the front end of the push rod 11, and a first end cap 14 sleeved on the outer ring of the rotating shaft 3.

[0024] Furthermore, the first bevel gear 4 meshes with the second bevel gear 7, and the fixed rod 5 and the connecting rod 6 form a rotating structure. With the first bevel gear 4 in place, when the rotating shaft 3 rotates, the first bevel gear 4 rotates synchronously, and through precise meshing with the second bevel gear 7, the horizontal rotational power of the rotating shaft 3 is converted into the vertical rotational power of the connecting rod 6.

[0025] Furthermore, a roller 15 is fixedly installed at the rear end of the first end cover 14. The outer wall of the pressing block 13 is tightly fitted with the inner wall of the roller 15. Through the setting of the pressing block 13, when the rotating shaft 3 drives the bevel gear set to transmit power, the pressing block 13 can make stable reciprocating motion along the inner wall of the roller 15 under the push of the push rod 11, continuously applying uniform extrusion pressure to the filter strip, which can actively squeeze out the interstitial water and part of the bound water in the filter strip, greatly reducing the water content of the filter strip.

[0026] Furthermore, a filter cloth 16 is fitted around the outer ring of the drum 15, and a spiral heat-absorbing tube 17 is fitted around the outer ring of the filter cloth 16. A feed inlet 18 is provided at the upper end of the drum 15. Through the spiral heat-absorbing tube 17, circulating cold water can be introduced into the spiral heat-absorbing tube 17. The cold water absorbs the residual heat during the flow inside the tube and is converted into warm water with a certain temperature before being discharged. It can be used again for preheating the clean water in the subsequent washing process, or supplied to other auxiliary processes of the device that require a low-temperature heat source.

[0027] Furthermore, water inlet pipes 19 are fixedly installed through both ends of the first end cap 14, and steam pipes 20 are fixedly installed through both ends of the first end cap 14. Through the setting of the steam pipes 20, the pipe openings can be precisely aligned with the forming area of ​​the filter strips inside the drum 15, and low-temperature steam can be directionally introduced. This can effectively soften the sugar and sticky impurities remaining on the surface of the filter strips, preventing impurities from adhering to the pores of the filter cloth 16 and causing blockage. At the same time, it can also slightly reduce the viscosity of the water inside the filter strips, creating favorable conditions for subsequent dehydration. After the low-temperature steam introduced through the steam pipes 20 completes the washing, the residual heat it carries will be transferred through the filter cloth 16 to the outer spiral heat absorption pipe 17, and absorbed by the circulating water inside the pipe to achieve residual heat recovery and avoid heat waste.

[0028] Furthermore, a second end cap 21 is fixedly installed at the front end of the bracket 2. The front end of the second end cap 21 is connected to the roller 15, and the rear end of the second end cap 21 is fixedly connected to the limiting ring 12. Through the setting of the limiting ring 12, its inner hole is in sliding fit with the outer wall of the push rod 11, thus defining a unique trajectory for the linear reciprocating motion of the push rod 11.

[0029] Furthermore, a drive motor 22 is provided at the upper end of the base 1. The output end of the drive motor 22 is connected to the belt 23 through a synchronous pulley. The belt 23 is connected to the reducer 24 through another set of synchronous pulleys. The output end of the reducer 24 is connected to the rotating shaft 3 through a coupling. The reducer 24, model RV63-150, can reduce the high-speed output of the motor to a low speed that matches the rotation of the drum 15 and the movement of the pressing mechanism, and can also synchronously amplify the torque to overcome the transmission and pressing resistance.

[0030] Working principle: Power is provided by the drive motor 22 at the upper end of the base 1. Its output end transmits the power to the reducer 24 through the synchronous pulley and belt 23. The reducer 24 converts the high-speed power into a suitable speed and torque through the reduction and torque amplification effect, and then transmits it to the rotating shaft 3 fixed through both ends of the bracket 2 through the coupling, driving the rotating shaft 3 to rotate stably. When the rotating shaft 3 rotates, the first bevel gear 4 fixed on its outer ring rotates synchronously. Because the first bevel gear 4 meshes with the second bevel gear 7 on the outer ring of the connecting rod 6 connected through both ends of the fixed rod 5, the horizontal rotational power of the rotating shaft 3 is converted into the vertical rotational power of the connecting rod 6, so that the connecting rod 6 rotates stably with the fixed rod 5 as support. The rotation of the connecting rod 6 drives the connecting ring 8 on its outer ring to move. The slider 9 fixed at the front end of the connecting ring 8 then slides back and forth in the slide 10. The slide 10 converts the circular motion of the slider 9 into the linear reciprocating motion of the push rod 11. When the push rod 11 moves, the limiting ring 12 on its outer ring constrains the trajectory of the push rod 11 to prevent deviation. It pushes the pressing block 13 to stick tightly to the inner wall of the drum 15 and make stable reciprocating motion. Yeast milk is introduced from the feed port 18 at the top of the drum 15. The water inlet pipe 19 penetrating both ends of the first end cover 14 introduces clean water and the steam pipe 20 introduces low-temperature steam for washing to remove residual impurities. During the washing process, the spiral heat absorption pipe 17 on the outer ring of the filter cloth 16 introduces circulating cold water to absorb the residual heat of the steam and clean water and convert it into warm water for recycling. The vacuum system inside the drum 15 is activated to form negative pressure. The liquid in the yeast milk is extracted through the filter cloth 16, and the solid forms a filter strip. Finally, through the synergy of mechanical pressing and vacuum dehydration, efficient and energy-saving solid-liquid separation is achieved.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
