Description

Technical Field

[0001] The invention relates to the technical field of pulverizing equipment, in particular to a continuous pulverizing and screening equipment for the production of lactase. Background Art

[0002] Lactase is a commonly used digestive aid. Its main ingredient is a dry preparation of live enterococci. The processing steps of lactase include strain purification, culture medium preparation, inoculation, fermentation, bacterial separation, drying, crushing, mixing, etc., among which air flow mills are mostly used for crushing.

[0003] The working principle of the air flow mill is to use high-speed airflow (usually compressed air or inert gas) to make the material particles collide and rub against each other in the crushing chamber to achieve crushing. The crushed material particles enter the classification area with the airflow, and the fine particles that meet the requirements are carried out of the classification area by the airflow and enter the collection system.

[0004] The patent with the patent publication number CN117244668A discloses a biological hemostatic material crushing and screening system, including legs, a rectangular shell, a cylindrical crushing chamber, a crushing component, a wall scraping component and a discharging component. The system solves the problem that when the existing airflow crushing equipment is in use, the fibrinogen frozen blocks and thrombin frozen blocks in the equipment are only subjected to the linear force of the airflow ejected from the nozzle, resulting in poor crushing effect, and the materials deviating from the airflow direction cannot be subjected to the impact force of the airflow, resulting in incomplete crushing. The system also solves the problem that during crushing, since the fibrinogen frozen blocks and thrombin frozen blocks still contain a certain amount of moisture, the fibrinogen coarse powder and the thrombin coarse powder are easily adhered to the inner wall of the crushing chamber and agglomerated, which reduces the crushing effect and makes the mixing uniformity of the two poor.

[0005] The prior art has the following defects: When the air flow mill is working, a collision airflow is first formed in the equipment, and then the powder is directly put into the equipment. The powder is affected by the airflow and is entrained into the same motion trajectory, where it collides and is crushed. However, due to the large internal space of the equipment, the airflow begins to disperse after flowing out of the injection pipe, and the entrainment effect on the powder decreases. The size of the powder particles also affects the synchronous movement of the powder and the airflow. These situations will affect the crushing effect of the equipment, resulting in the powder particles being unable to be sieved and needing to be crushed again, affecting processing efficiency.

[0006] The air flow mill needs to use a high-speed motor, and when the high-speed motor is in use, it will emit a lot of heat. This heat may cause the output power of the high-speed motor to decrease, resulting in a lot of energy waste and is not conducive to the stable operation of the air flow mill. Summary of the invention

[0007] In view of the problem that the air flow inside the prior art equipment is dispersed, which affects the pulverizing effect, a continuous pulverizing and screening equipment for lactase production is proposed.

[0008] The present application provides a continuous crushing and screening device for the production of lactase, the purpose of which is to make full use of the power of airflow.

The powder storage table is annular. The feeding interface is located at the part of the diverter pipe extending into the bottom cylinder. The feeding pipe extends downward into the feeding interface. The feeding pipe extends into the grinding cylinder body, and the lower end opening is located above the powder storage tank.

[0010] Furthermore, the crushing cylinder body is divided into a bottom cylinder, a middle cylinder and a top cylinder from bottom to top, the air blowing device is located outside the bottom cylinder, the feeding assembly and the feeding pipe are respectively distributed on the inner and outer sides of the middle cylinder, and the discharge pipe and the screening device are installed on the top cylinder.

[0011] Furthermore, the feeding assembly also includes an inner guide sleeve arranged inside the powder storage table, the inner guide sleeve is annular, and its outer contour fits the inner circle of the powder storage table, the top of the inner guide sleeve extends upward from the powder storage table, and the extended part is configured to be conical.

[0012] Furthermore, the feeding assembly further comprises an external guide sleeve arranged inside the internal guide sleeve, and a through-hole is provided on the surface of the external guide sleeve; The external guide sleeve is annular, and the upper and lower ends of the internal guide sleeve are both installed on the surface of the external guide sleeve. The lower end of the external guide sleeve extends downward out of the powder storage platform, and the extended part is set to be conical.

[0013] Furthermore, the bottom wall of the powder storage tank is designed to be inclined, wherein the side directly below the feeding pipe is the highest and the other side is the lowest.

[0014] Furthermore, the feeding assembly also includes a bottom ring and an upper ring arranged inside the powder storage tank, a mounting opening opened on the surface of the bottom ring, a screen arranged inside the mounting opening, a leakage opening opened on the surface of the upper ring, a scraper arranged at the bottom of the upper ring, an external interface opened on the surface of the internal guide sleeve, a power motor arranged on the inner wall of the internal guide sleeve, a gear arranged at the power output end of the power motor, and a side opening opened on the inner ring wall of the powder storage table; The installation port is connected to the discharge port, the upper ring is located above the bottom ring, the scraper is attached to the upper surface of the bottom ring, and the bottom of the inner ring of the upper ring is provided with a tooth groove corresponding to the gear. The gear passes through the external interface and the side opening and meshes with the tooth groove of the upper ring.

[0015] Furthermore, a limiting ring is fixedly connected to the interior of the middle cylinder, and the powder storage platform is pressed against the bottom of the limiting ring.

[0016] Furthermore, the screening device specifically includes a screen wheel arranged at one end of the discharge pipe located in the top cylinder, a docking port opened at one end of the screen wheel away from the discharge pipe, and an energy-saving motor arranged outside the top cylinder; The docking port is arranged horizontally, and the power output shaft of the energy-saving motor is clamped in the docking port.

[0017] Furthermore, the screening device also includes an auxiliary energy-saving component, which specifically includes a connecting sleeve arranged at one end of the energy-saving motor away from the top cylinder, a water cooling jacket arranged outside the energy-saving motor, and a circulation pipe arranged outside the water cooling jacket; The water cooling jacket is fixed to the connecting jacket, the interior of the water cooling jacket is filled with coolant, the circulation connecting pipe is connected into the water cooling jacket, and the water cooling jacket is wrapped around the outside of the energy-saving motor.

[0018] Beneficial effects of the present invention: 1. By setting up the feeding pipe and the blowing equipment, the airflow blown by the blower is dispersed into the various diversion pipes by the diversion box, and the air is blown into the bottom cylinder. After the powder is put into the powder storage tank, it is dispersed and thrown out by the feeding pipes at various places. The powder enters the diversion pipe and is pushed out by the high-speed airflow. Then the powder in the diversion pipes at various places collides and crushes at the center of the bottom cylinder. In this way, before the powder collides, it can obtain the maximum power from the airflow that has not yet been dispersed, so as to enhance the crushing effect and improve the crushing efficiency.

[0019] 2. By setting up the screening equipment, the energy-saving motor drives the screen wheel to rotate at high speed during operation. The powder is crushed and flows upward with the air flow. When the powder reaches the energy-saving motor, the qualified powder passes through the screen wheel and enters the discharge pipe, and the unqualified powder is intercepted on the outside of the screen wheel and then thrown out by the high-speed rotating screen wheel. The thrown out powder falls and is crushed again, which can ensure the fineness of the product and improve the product quality.

[0020] 3. By setting up a water cooling jacket, the coolant in the water cooling jacket absorbs the heat dissipated by the energy-saving motor. After absorbing the heat, the coolant flows into the heat dissipation tower. The coolant with low temperature flows downward into the water cooling jacket and continues to absorb heat. The heat sink dissipates the heat in the heat dissipation tower into the air. This can effectively reduce the temperature of the energy-saving motor and protect the energy-saving motor. When the heat dissipation rate of the heat dissipation tower cannot meet the needs of the energy-saving motor, the condenser is started. The condenser circulates and cools the coolant in the water cooling jacket through the circulation pipe to ensure the stability of heat dissipation.

[0021] 4. By setting an internal guide sleeve and an external guide sleeve, the internal conical surface of the internal guide sleeve can send the powder intercepted and dropped by the screening equipment into the powder storage tank, which is convenient for the collection and re-collision crushing of the powder, and avoids the powder from falling from the rising area of ​​the air flow and affecting the flow of the powder. The external guide sleeve can gather the rising airflow and powder to the central axis of the equipment, separate it from the falling powder, and at the same time, it can also support each other with the internal guide sleeve, so that it can remain stable under the impact of high-speed airflow.

[0022] 5. The powder storage tank is designed to be inclined so that after the powder enters the powder storage tank, it slides down the slope so that the powder can be evenly distributed in the powder storage tank. Powder can enter each discharge port at the same time, ensuring that the powder is discharged evenly from each diversion pipe, which can produce more sufficient collision and help improve the crushing effect.

[0023] 6. By setting up a water cooling jacket, the coolant in the water cooling jacket absorbs the heat emitted by the energy-saving motor, and the condenser circulates and cools the coolant in the water cooling jacket through the circulation pipe, which starts the cooling effect on the energy-saving motor, ensures the stability of the output power of the energy-saving motor, and can play an energy-saving role.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] Example 1, reference Figure 1-Figure 6 , Figure 8-Figure 16 , which is the first embodiment of the present invention, provides a continuous crushing and screening equipment for lactase production, including a base 1, a crushing cylinder 2 arranged on the top of the base 1, a feeding pipe 3 arranged on the outside of the crushing cylinder 2, an aeration device 4, a screening device 5, a discharge pipe 6, and a feeding component 7 arranged inside the crushing cylinder 2.

[0028] Specifically, the crushing cylinder body 2 is divided into a bottom cylinder 21, a middle cylinder 22, and a top cylinder 23 from bottom to top, and the three are fixed by bolts. The air blowing device 4 is located on the outside of the bottom cylinder 21, and the feeding assembly 7 and the feeding pipe 3 are respectively distributed on the inner and outer sides of the middle cylinder 22. The feeding pipe 3 is welded to the middle cylinder 22, and the discharge pipe 6 and the screening device 5 are installed on the top cylinder 23.

[0029] By configuring the grinding cylinder body 2 to be multi-section, it is convenient to install and debug various components in the grinding cylinder body 2.

[0030] The screening device 5 specifically includes a screen wheel 51 arranged at one end of the discharge pipe 6 located in the top cylinder 23 , a docking port 52 opened at the end of the screen wheel 51 away from the discharge pipe 6 , and an energy-saving motor 53 arranged outside the top cylinder 23 .

[0031] Specifically, the discharge pipe 6 extends into the top cylinder 23, the screen wheel 51 is rotatably connected to the discharge pipe 6, the docking port 52 is horizontally arranged, the power output shaft of the energy-saving motor 53 is clamped in the docking port 52, and the energy-saving motor 53 is fixed to the surface of the top cylinder 23 by bolts.

[0032] By setting up the screening device 5, the energy-saving motor 53 drives the screen wheel 51 to rotate at a high speed during operation. The powder is crushed and flows upward with the air flow. When the powder reaches the energy-saving motor 53, the qualified powder passes through the screen wheel 51 and enters the discharge pipe 6, and the unqualified powder is intercepted on the outside of the screen wheel 51 and then thrown out by the high-speed rotating screen wheel 51. The thrown out powder falls and is crushed again, so that the fineness of the product can be guaranteed and the product quality can be improved.

[0033] The screening device 5 further includes an auxiliary energy-saving component, which specifically includes a connecting sleeve 54 disposed at one end of the energy-saving motor 53 away from the top cylinder 23, a water cooling jacket 55 disposed outside the energy-saving motor 53, and a circulation pipe 56 disposed outside the water cooling jacket 55; The connecting sleeve 54 is fixed to the energy-saving motor 53 by bolts, the water cooling jacket 55 is fixed to the connecting sleeve 54, the water cooling jacket 55 is sleeved on the outside of the connecting sleeve 54, the energy-saving motor 53 is welded together, the circulation pipe 56 is connected to the water cooling jacket 55, the other end of the circulation pipe 56 is connected to the condenser, and the water cooling jacket 55 is wrapped around the outside of the energy-saving motor 53.

[0034] By setting up the water cooling jacket 55, the coolant in the water cooling jacket 55 absorbs the heat emitted by the energy-saving motor 53, and the condenser circulates and cools the coolant in the water cooling jacket 55 through the circulation pipe 56, thereby cooling the energy-saving motor 53, ensuring the stability of the output power of the energy-saving motor 53, and achieving energy-saving effect.

[0035] The aeration device 4 specifically includes a joint 41 and a diverter box 42 arranged on the outside of the grinding cylinder body 2, and a diverter pipe 43 arranged between the joint 41 and the diverter box 42; the feeding assembly 7 specifically includes a powder storage table 71 arranged inside the middle cylinder 22, a powder storage tank 72 arranged on the top of the powder storage table 71, a discharge port 73 arranged at the bottom of the powder storage table 71, a feeding pipe 74 arranged inside the discharge port 73, and a feeding interface 75 arranged on the outside of the diverter pipe 43.

[0036] Specifically, the joint 41 is welded to the surface of the bottom cylinder 21 and is distributed in a circular array around the bottom cylinder 21. The diverter box 42 is sleeved on the outside of the bottom cylinder 21 and the two are fixed by bolts. The diverter box 42 is connected to the blower through the airflow input pipe. One end of the diverter pipe 43 passes through the joint 41 and extends into the bottom cylinder 21 and is fixed to the joint 41 by bolts. The other end of the diverter pipe 43 is connected to the diverter box 42 and the two are fixed by bolts. The powder storage table 71 is annular and is fixed to the middle cylinder 22 by bolts. The discharge port 73 The number and position correspond to the diverter pipe 43, the discharge port 73 is connected to the powder storage tank 72, the feeding pipe 74 is threadedly connected to the discharge port 73, the feeding pipe 74 extends downward into the feeding interface 75, the feeding interface 75 is located at the part where the diverter pipe 43 extends into the bottom cylinder 21, the feeding pipe 3 extends into the grinding cylinder body 2, and the lower end opening is located above the powder storage tank 72; the interior of the middle cylinder 22 is fixedly connected to the limit ring 719, and the powder storage table 71 is pressed against the bottom of the limit ring 719, which facilitates the installation of the powder storage table 71.

[0037] By setting the feeding pipe 3 and the blowing device 4, the airflow blown by the blower is dispersed into the various diverter pipes 43 by the diverter box 42, and the air is blown into the bottom cylinder 21. After the powder is put into the powder storage tank 72, it is dispersed and thrown out by the feeding pipes 74 at various locations. The powder enters the diverter pipe 43 and is pushed out by the high-speed flowing airflow. Subsequently, the powder in the various diverter pipes 43 collides and is crushed at the center of the bottom cylinder 21. In this way, before the powder collides, it can obtain the maximum power from the airflow that has not yet been dispersed, so that the crushing effect is enhanced and the crushing efficiency is improved.

[0038] Specifically, the feeding assembly 7 further includes an inner guide sleeve 76 disposed inside the powder storage platform 71 , an outer guide sleeve 77 disposed inside the inner guide sleeve 76 , and a through hole 78 opened on the surface of the outer guide sleeve 77 .

[0039] The internal guide sleeve 76 is annular in shape, and its outer contour fits the inner circle of the powder storage platform 71, and the two are fixed by bolts. The top of the internal guide sleeve 76 extends upward from the powder storage platform 71, and the extended part is set to a cone. The bottom edge of the cone at the top of the internal guide sleeve 76 is located at the opening edge above the powder storage groove 72. The external guide sleeve 77 is annular in shape, and the upper and lower ends of the internal guide sleeve 76 are installed on the surface of the external guide sleeve 77 by bolts. The lower end of the external guide sleeve 77 extends downward from the powder storage platform 71, and the extended part is set to a cone. The feeding pipe 74 passes through the insertion hole 78, and the bottom edge of the cone at the bottom end of the internal guide sleeve 76 fits the inner wall of the middle cylinder 22.

[0040] By providing an internal guide sleeve 76 and an external guide sleeve 77, the internal conical surface of the internal guide sleeve 76 can send the powder intercepted and dropped by the screening device 5 into the powder storage tank 72, which facilitates the collection and re-collision crushing of the powder, and avoids the powder from falling from the rising area of ​​the air flow and affecting the flow of the powder. The external guide sleeve 77 can gather the rising airflow and powder to the central axis of the equipment, separate it from the falling powder, and at the same time can also play a role of mutual support with the internal guide sleeve 76, so that it can remain stable under the impact of high-speed airflow.

[0041] Example 2, reference Figure 5-Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that the bottom wall of the powder storage tank 72 is designed to be inclined, wherein the side directly below the feeding pipe 3 is the highest and the other side is the lowest.

[0042] By designing the powder storage tank 72 to be inclined, after the powder enters the powder storage tank 72, it slides down along the inclined surface so that the powder can be evenly distributed in the powder storage tank 72. Powder can enter each discharge port 73 at the same time, ensuring that the powder is discharged evenly from each diversion pipe 43, which can produce more sufficient collisions and help improve the crushing effect.

[0043] Example 3, reference Figure 4-Figure 6 , Figure 14-15 , which is the third embodiment of the present invention. This embodiment is different from the first embodiment in that: the feeding assembly 7 also includes a bottom ring 79 and an upper ring 712 arranged inside the powder storage tank 72, a mounting port 710 opened on the surface of the bottom ring 79, a screen 711 arranged inside the mounting port 710, a leakage port 713 opened on the surface of the upper ring 712, a scraper 714 arranged at the bottom of the upper ring 712, an external interface 715 opened on the surface of the internal guide sleeve 76, a power motor 716 arranged on the inner wall of the internal guide sleeve 76, a gear 717 arranged at the power output end of the power motor 716, and a side opening 718 opened on the inner ring wall of the powder storage table 71.

[0044] Specifically, the bottom ring 79 is placed in the powder storage tank 72, the installation port 710 is connected to the discharge port 73, the screen 711 is clamped in the installation port 710, and the installation port 710 extends into the discharge port 73, so that the bottom ring 79 cannot move in a circle, the upper ring 712 is located above the bottom ring 79, the scraper 714 is fixed to the upper ring 712 by bolts, the scraper 714 is attached to the upper surface of the bottom ring 79, and a horizontal platform is provided at the connection between the lower end of the inner guide sleeve 76 and the outer guide sleeve 77. The power motor 716 is installed on the horizontal platform by bolts. The bottom of the inner ring of the upper ring 712 is provided with a tooth groove corresponding to the gear 717. The gear 717 passes through the external interface 715 and the side opening 718 and meshes with the tooth groove of the upper ring 712. When standing still, the powder cannot pass through the screen 711.

[0045] By setting the bottom ring 79 and the upper ring 712, after the powder is put in, the powder falls on the top of the bottom ring 79, and the upper ring 712 drives the scraper 714 to rotate. Every time the scraper 714 passes through the screen 711, part of the powder will pass through the screen 711 and fall into the feeding pipe 74, and then be blown out by the airflow. In this way, the ratio of the airflow and the powder in the airflow can be controlled to avoid excessive powder, which will weaken the force of the airflow on it and affect the impact effect. At the same time, the feeding of the powder is controlled by the upper ring 712 to avoid the powder from falling into the diverter pipe 43 when the equipment is paused, thereby avoiding the accumulation of powder in the diverter pipe 43.

[0046] Based on Examples 1 and 3, the working principle of the continuous crushing and screening equipment for lactase production of the present invention is as follows: During installation, first install the screen 711 into the installation opening 710, then place the bottom ring 79 into the powder storage tank 72, align the installation opening 710 and the discharge opening 73, insert the screen 711 into the discharge opening 73, and then use bolts to fix the scraper 714 to the bottom of the upper ring 712, and then place the upper ring 712 into the powder storage tank 72; turn the conical surface of the top of the inner guide sleeve 76 backward and insert it from the side of the powder storage platform 71 where the powder storage tank 72 is provided, and place the edge of the inner guide sleeve 76 on the top of the powder storage platform 71, fix it with bolts, and then turn the power on. The motor 716 is sent into the inner guide sleeve 76 to make it close to the outer interface 715, and then the gear 717 is pushed horizontally to pass through the side opening 718 to enter the powder storage tank 72 and engage with the upper ring 712, fix the power motor 716, and then the conical surface at the bottom of the external guide sleeve 77 is turned backward and inserted from the end of the inner guide sleeve 76 without a conical surface, and then fixed with bolts; the feeding pipes 74 are inserted into the discharge port 73 one by one, and finally the powder storage table 71 is inserted into the middle cylinder 22, so that the powder storage table 71 is pressed against the limit ring 719 and fixed with bolts.

[0047] First, fix the bottom cylinder 21 on the top of the base 1, and then sleeve the diverter box 42 from top to bottom on the outside of the bottom cylinder 21, insert one end of the diverter pipe 43 into the diverter box 42, and insert the other end into the joint 41 to connect the bottom cylinder 21 and the diverter box 42, and connect the diverter box 42 to the blower; place the middle cylinder 22 above the bottom cylinder 21, and the feeding pipe 74 first enters the bottom cylinder 21, and then inserts it into the feeding interface 75 one by one to fix the middle cylinder 22 and the bottom cylinder 21; rotatably install the sieve wheel 51 on one end of the discharge pipe 6, and then insert the sieve wheel 51 from one side of the top cylinder 23, insert the energy-saving motor 53 from the other side, insert the power output shaft of the energy-saving motor 53 into the docking interface 52, and finally place the top cylinder 23 above the middle cylinder 22 and fix it with bolts.

[0048] When in use, turn on the blower, and the blower fills air into the diverter box 42. The air flows into the bottom cylinder 21 from the diverter pipes 43 at various locations, and the air flowing out at high speed from the diverter pipes 43 collides at the central axis of the bottom cylinder 21. The airflow after the collision rises and enters the sieve wheel 51. Turn on the energy-saving motor 53 to drive the sieve wheel 51 to rotate at high speed.

[0049] Powder is poured in from the feeding pipe 3, and the powder enters the powder storage tank 72. Then the external interface 715 is started. The external interface 715 drives the upper ring 712 to rotate in the powder storage tank 72 through the gear 717. The upper ring 712 rotates to spread the powder in the powder storage tank 72. Due to the tension between the powders, a large amount of powder will not leak from the top of the screen 711. Through the brushing of the upper ring 712, the powder begins to fall evenly and regularly. The powder falls into the diversion pipe 43 through the feeding pipe 74, and is then instantly pushed out by the high-speed flowing air, and collides and breaks at the central axis of the bottom cylinder 21.

[0050] The powder after the collision rises with the airflow, flows through the center of the external guide sleeve 77, and finally approaches the screen wheel 51. The powder with qualified particles passes through the screen wheel 51 and is discharged by the discharge pipe 6. The unqualified powder first adheres to the surface of the screen wheel 51, and is then thrown out by the high-speed rotating screen wheel 51 through centrifugal force. The unqualified powder is thrown to the inner wall of the top cylinder 23, separated from the rising airflow, and then falls into the powder storage tank 72 for secondary collision and crushing.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
