Description

Technical Field

[0001] The invention relates to the technical field of Bacillus subtilis production equipment, in particular to a filtering device for Bacillus subtilis production. Background Art

[0002] Bacillus subtilis is a Gram-positive bacterium, also often called Bacillus subtilis. It belongs to the genus Bacillus and is widely used in agricultural production. In the agricultural field, Bacillus subtilis is an important ingredient in biological pesticides and biological fertilizers, with broad-spectrum antibacterial activity and the effect of promoting plant growth.

[0003] When producing Bacillus subtilis, it is generally necessary to filter the stock solution to remove the impurities contained therein. During production, it needs to be fermented. After the fermentation is completed, in addition to the target product (such as metabolites, enzymes, etc.), the fermentation liquid also contains a large amount of bacterial cells, incompletely utilized culture medium components, by-products in the metabolites, and other impurities that may be produced. By filtering, these impurities can be effectively removed, and the purity of the target product can be improved, so that it is convenient to perform secondary filtration using a microporous membrane method to make the stock solution purer and meet the use requirements. However, the existing filtering device is inefficient in filtering the stock solution during use, and the impurities accumulated at the filter screen make it impossible to filter out the stock solution smoothly. Improvements need to be made to this problem. Summary of the invention

[0004] The object of the present invention is to provide a filtering device for producing Bacillus subtilis to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a filtering device for producing Bacillus subtilis, comprising a filter, a driving assembly, a connecting assembly and an extrusion assembly, a protective cover is arranged on the top of the filter, and a filter basket is fixedly connected inside the filter.

[0006] Wherein, the driving component comprises:

[0007] A driving motor is fixedly connected to the middle of the bottom of the filter. The driving motor has an output shaft. The output shaft of the driving motor is fixedly connected to a rotating shaft. The top of the rotating shaft is fixedly connected to a rotating cylinder. The bottom of the outer side of the rotating cylinder is fixedly connected to a rotating arm. The bottom of the rotating arm is rotatably connected to a cleaning roller 1. The side of the rotating arm close to the inner wall of the filter basket is rotatably connected to a cleaning roller 2.

[0008] According to the above technical solution, the connecting assembly includes an electric telescopic rod, a lifting rod, a lifting frame, a telescopic plate and a push-pull frame, the electric telescopic rod is fixedly connected to the inner bottom of the rotating shaft, the electric telescopic rod has a telescopic end, the lifting rod is fixedly connected to the telescopic end of the electric telescopic rod, the lifting frame is fixedly connected to the outside of the lifting rod, the telescopic plate is rotatably connected to the middle part of the lifting frame, and the push-pull frame is rotatably connected to the side of the telescopic plate away from the lifting frame.

[0009] According to the above technical solution, the extrusion assembly includes a guide frame, a support plate, a spring, a movable slider, a push rod, a rotating plate and a cleaning roller. The guide frame is fixedly connected to the outside of the rotating cylinder, the support plate is respectively fixedly connected to the front and back sides of the guide frame, the spring is fixedly connected to the side of the support plate close to the rotating cylinder, the movable slider is fixedly connected to the other end of the spring, the push rod is fixedly connected to the side of the movable slider away from the rotating cylinder, the rotating plate is fixedly connected to the other end of the push rod, and the cleaning roller is rotatably connected to the outside of the rotating plate.

[0010] According to the above technical solution, the output shaft of the driving motor passes through the middle of the bottom of the filter and extends into the filter and is fixedly connected to the bottom of the rotating shaft. The top of the rotating cylinder passes through the bottom of the filter basket and extends into the inside of the filter basket, and the rotating cylinder is rotatably connected to the inner wall of the bottom of the filter basket. The bottom of the cleaning roller 1 contacts the inner wall of the bottom of the filter basket, and the outer side of the cleaning roller 2 contacts the outer inner wall of the filter basket. A rectangular groove for accommodating the rotation of the telescopic plate is provided on the outer side of the rotating cylinder, so that the telescopic plate can rotate in the rectangular groove on the rotating cylinder.

[0011] According to the above technical solution, the telescopic end of the electric telescopic rod passes through the top of the rotating shaft and the bottom of the rotating cylinder and extends into the rotating cylinder and is fixedly connected to the lifting rod. The bottom of the push-pull frame is fixedly connected to the top of the movable slider, so that the push-pull frame can synchronously push the movable slider to move when force is applied.

[0012] According to the above technical solution, sliders are provided on the front and back of the movable slider, a slide groove is provided in the guide frame, the movable slider is slidably connected with the slide groove on the guide frame through the slider, and the spring is fixedly connected to the slider at one end away from the support plate, so that the spring can elastically support the support plate.

[0013] According to the above technical solution, the end of the push rod away from the moving slider passes through the middle of the outer side of the guide frame and extends to the outer side of the guide frame and is fixedly connected to the rotating plate, so that when the push rod moves, it pushes the rotating plate to move synchronously.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: in the present invention, when filtering is required during the production of Bacillus subtilis, the protective cover is opened, the stock solution is placed in the filter basket, and then the driving motor is started. The driving motor drives the rotating shaft and the rotating drum at the top to rotate during operation. At this time, the rotating drum can accelerate the flow speed of the stock solution in the filter basket during rotation. At the same time, the cleaning rollers 1 and 2 on the rotating drum contact the inner wall of the bottom of the filter basket, and the impurities accumulated on the inner wall of the filter basket can be turned over to avoid the accumulation of impurities causing the filter basket to fail to filter normally. The stock solution entering the filter basket can be filtered on a basic basis, and obvious large impurities can be intercepted, so as to facilitate subsequent filtration by the microporous membrane method.

[0015] When filtering, the driving motor controls the rotating drum to rotate. When the driving motor rotates faster, the centrifugal force on the guide frame increases. At the same time, the spring is stretched as the centrifugal force increases, so that the movable slider slides outward on the guide frame. At the same time, the spring is compressed, so that the movable slider pushes the rotating plate through the push rod, so that the cleaning roller three contacts the inner wall of the filter basket. When filtering, it can continuously fit the inner wall of the filter basket and roll on the inner wall of the filter basket, so as to sweep away the impurities adhering to the inner wall of the filter basket, and avoid the impurities from clogging the inner wall of the filter basket.

[0016] During filtration, the rotating plate outside the rotating cylinder rotates with the operation of the driving motor. When the rotating plate rotates, the rotating plate can quickly flip the raw liquid in the filter basket, so that the raw liquid flows faster in the filter basket, thereby increasing the filtering efficiency of the raw liquid.

[0017] After the filtration is completed, due to the water-absorbing property of impurities, a certain amount of raw liquid exists in the impurities, and the electric telescopic rod is controlled to work. When the electric telescopic rod is working, it drives the lifting rod to move downward, so that the lifting frame on the lifting rod squeezes the telescopic plate, and the telescopic plate pushes the push-pull frame. At this time, the moving slider at the bottom of the push-pull frame pushes the push rod to move, so that the cleaning roller three on the rotating plate contacts the impurities on the inner wall of the filter basket and squeezes it. During the squeezing, the raw liquid adsorbed in the impurities can directly flow out through the outer wall of the filter basket, making the device more efficient when filtering.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figure 1-4 The present invention provides a technical solution: a filtering device for producing Bacillus subtilis, comprising a filter 1, a driving assembly 4, a connecting assembly 5 and an extrusion assembly 6. A protective cover 2 is provided on the top of the filter 1, and a filter basket 3 is fixedly connected to the filter 1.

[0030] Wherein, the driving component 4 comprises:

[0031] The driving motor 401 is fixedly connected to the middle of the bottom of the filter 1. The driving motor 401 has an output shaft. The output shaft of the driving motor 401 is fixedly connected to the rotating shaft 402. The top of the rotating shaft 402 is fixedly connected to the rotating cylinder 403.

The rotating arm 404 is rotatably connected to a cleaning roller 2 406 on the side close to the inner wall of the filter basket 3.

[0032] The output shaft of the driving motor 401 passes through the middle of the bottom of the filter 1 and extends into the filter 1 to be fixedly connected to the bottom of the rotating shaft 402. The top of the rotating cylinder 403 passes through the bottom of the filter basket 3 and extends into the inside of the filter basket 3.

[0035] The extrusion assembly 6 includes a guide frame 601, a support plate 602, a spring 603, a movable slider 604, a push rod 605, a rotating plate 606 and a cleaning roller three 607. The guide frame 601 is fixedly connected to the outer side of the rotating cylinder 403, the support plate 602 is respectively fixedly connected to the front and back sides of the guide frame 601, the spring 603 is fixedly connected to the side of the support plate 602 close to the rotating cylinder 403, the movable slider 604 is fixedly connected to the other end of the spring 603, the push rod 605 is fixedly connected to the side of the movable slider 604 away from the rotating cylinder 403, the rotating plate 606 is fixedly connected to the other end of the push rod 605, and the cleaning roller three 607 is rotatably connected to the outer side of the rotating plate 606.

[0036] The telescopic end of the electric telescopic rod 501 passes through the top of the rotating shaft 402 and the bottom of the rotating cylinder 403 and extends into the rotating cylinder 403 to be fixedly connected to the lifting rod 502. The bottom of the push-pull frame 505 is fixedly connected to the top of the moving slider 604, so that the push-pull frame 505 can synchronously push the moving slider 604 to move when force is applied.

[0037] The movable slider 604 is provided with sliders on the front and back sides, and a slide groove is provided in the guide frame 601. The movable slider 604 is slidably connected with the slide groove on the guide frame 601 through the slider. The end of the spring 603 away from the support plate 602 is fixedly connected to the slider, so that the spring 603 can elastically support the support plate 602.

[0038] One end of the push rod 605 away from the moving slider 604 passes through the middle of the outer side of the guide frame 601 and extends to the outer side of the guide frame 601 and is fixedly connected to the rotating plate 606, so that when the push rod 605 moves, it pushes the rotating plate 606 to move synchronously.

[0039] When filtering, the driving motor 401 controls the rotating drum 403 to rotate. When the driving motor 401 rotates faster, the centrifugal force on the guide frame 601 increases. At the same time, the spring 603 is stretched as the centrifugal force increases, and the telescopic plate 504 is stretched, so that the movable slider 604 slides outward on the guide frame 601.

When filtering, it can continue to fit the inner wall of the filter basket 3 and roll on the inner wall of the filter basket 3, so as to sweep away the impurities adhering to the inner wall of the filter basket 3, and avoid the impurities from clogging the inner wall of the filter basket 3.

[0040] When filtering, the rotating plate 606 on the outside of the rotating cylinder 403 rotates as the driving motor 401 works. When the rotating plate 606 rotates, the rotating plate 606 can quickly flip the raw liquid in the filter basket 3, so that the flow speed of the raw liquid in the filter basket 3 is accelerated, thereby increasing the filtering efficiency of the raw liquid.

[0041] After the filtration is completed, due to the water-absorbing property of the impurities, a certain amount of raw liquid exists in the impurities, and the electric telescopic rod 501 is controlled to work. When the electric telescopic rod 501 works, it drives the lifting rod 502 to move downward, so that the lifting frame 503 on the lifting rod 502 squeezes the telescopic plate 504, and the telescopic plate 504 pushes the push-pull frame 505. At this time, the moving slider 604 at the bottom of the push-pull frame 505 pushes the push rod 605 to move, so that the cleaning roller three 607 on the rotating plate 606 contacts the impurities on the inner wall of the filter basket 3 and squeezes them. During the squeezing, the raw liquid adsorbed in the impurities can directly flow out through the outer wall of the filter basket 3, so that the device is more efficient when filtering.
