Description

Pneumatic conveying and batching mechanism

Technical field

The present invention relates to the field of cooking ingredients, and more particularly to a pneumatic conveying ingredient mechanism.

Background technique

Seasoning is a kind of cooking material that is indispensable in daily cooking. According to its physical form, it can be divided into solid and liquid. Among them, solid seasoning or material can also include salt, sugar, chicken, pepper, Small granular or powdery materials such as pepper powder. In the field of cooking, these solid seasonings or materials are generally placed in a plurality of different seasoning bottles or seasoning boxes, placed in the kitchen, manually opened by the user during use, and manually placed in the seasoning bottle Or the seasoning in the seasoning box is put into the wok, the method of taking the material is cumbersome and backward, and the manual feeding method is adopted, it is difficult to ensure the quantitative supply of the seasoning, which seriously affects the cooking effect.

With the development of science and technology, more and more smart kitchen equipment capable of realizing automatic quantitative configuration of spices has emerged. For example, patent CN103169404A discloses an instant batching machine, including a storage cabinet, a control unit and a base, wherein the storage cabinet The utility model comprises a plurality of storage cells, each storage cell is used for storing various seasonings, and when a command is input through the control unit, each corresponding storage cell will cause the loaded seasoning to fall to a predetermined amount. Instant and automatic dispensing of seasonings can be achieved by such an instant batching machine, and the time for measuring the amount of seasonings can be saved, and the problem of inconsistent taste caused by human factors can be reduced. However, such instant batching machines are generally large in size, and can only realize the instant automatic configuration of seasonings, and can not realize the conveying of seasonings. Therefore, it is generally necessary to place around the pots in order to realize the instant of seasonings more efficiently. Add, this implementation is not flexible enough, seriously affecting the stove space.

For example, the patent CN101613036A discloses a method and a device for uniformly conveying and adding seasoning, which is composed of a frame body, a hopper, a screw feeding tube and a swinging mechanism, and carries a forward spiral conveying and seasoning through a screw feeding tube, and drives the screw feeding tube through the swinging mechanism. Perform a left and right swing to evenly discharge the spiral feed pipe outlet. The scheme can realize automatic feeding and uniform feeding of the seasoning. However, when the spiral feeding tube is screwed forward and conveyed, the conveying efficiency is slow, and the length of the spiral feeding tube is not designed to be too long, otherwise the feeding efficiency and the swing will be affected. The discharge rate, therefore, can not achieve long-distance rapid delivery of seasoning.

Further, as disclosed in the patent CN203723945U, a cooking dosing device is disclosed, comprising a dosing component for dispensing a solid material; a spraying component for sucking a solid material; and a conveying component for using The solid material is conveyed by gas; and a separation member connected to the injection chamber through the conveying member for decelerating separation of the gas and the solid material. Through this kind of equipment, the materials automatically arranged by the batching parts can be conveyed and separated by means of automatic conveying, and the long-distance conveying of the materials can be realized, so that the batching parts do not need to be stacked together with the pots, thereby saving the space of the cooker, but in the scheme The separation component is installed above the cookware and will occupy a limited space above the cookware. For example, it may conflict with the installation position of the cooker hood; and if the separation component is too close to the cookware, it is easily affected by the temperature around the cookware when the material is removed. If the solid seasoning becomes damp, or if the separation part is too far from the pot, the solid seasoning is easy to spray to the outside of the pot when the material is being cut, causing waste of the seasoning; and the solid seasoning is automatically put into the pot through the separating part, Users who manually adjust the amount of seasoning for personal tastes cannot fully meet the requirements. On the basis of this solution, in the prior art, the separation component can also be installed not above the pot, but the separation component and the pot can be set separately, and then a receiving cup is placed under the separating component. The solid material after the separation component is decelerated and separated is sprayed into the receiving cup, and then manually fed into the pan by the user through the receiving cup. This method can avoid the above problems, but the cutting method is easy to cause the solid seasoning to be after the material is fogged. There is a phenomenon of residual or sticking on the wall of the cup.

Therefore, at present, there is no suitable dosing mechanism to solve the problem that the existing batching mechanism transports the solid seasoning over a long distance, and the seasoning after the material is easy to be atomized and diffused, and the wall of the receiving cup is liable to be residual or sticking. That is, the existing batching mechanism still needs improvement in realizing the unloading of the solid seasoning for long distance transportation.

detailed description

The present invention is described in detail by the following embodiments. However, those skilled in the art should understand that the following embodiments are not intended to limit the scope of the present invention, and any modifications and changes made on the basis of the present invention are within the scope of the present invention.

Referring to Figure 1 and Figure 2, the pneumatic conveying and dosing mechanism proposed by the present invention is mainly composed of a separating device 1, a conveying pipe 2 and a dosing member 3. The batching component 3 is used for dispensing solid materials, the conveying pipeline 2 is used for pneumatic conveying of the solid material dispensed by the batching component 3, and the separating device 1 is used for decelerating and separating the gas and solid materials conveyed by the conveying pipeline 2.

Specifically, the ingredient component 3 is used for manual or automatic configuration of the solid material. The preferred method of the present invention is to automatically configure the material, as shown in FIG. 1 or FIG. 2, respectively. When the material is automatically configured, the ingredient component 3 generally includes a solid storage. The hopper 31, the solid blanking module 32 and the discharge port 33. The solid stocker 31 is used for storing solid materials, including small granular or powdery materials such as salt, sugar, chicken essence, monosodium glutamate, sesame seeds, ginger grains, garlic grains, pepper powder, pepper powder, and chili powder. The solid blanking module 32 is used for automatically dispensing the solid material stored in the solids hopper 31, and the automatically dispensed solid material is discharged through the discharge port 33. In a specific implementation, the solid cutting module 32 can be implemented by means of screw pushing or gear pushing. Preferably, in order to achieve precise dosing, the solid cutting module 32 can also be communicably connected to a control module, and the solid cutting module 32 can The control command of the control module is precisely dosed. For example, the control module can measure the dosing amount of the solid material by means of the number of revolutions of the metering screw, etc., thereby sending a start batching or stopping the batching command to the solid cutting module 32 to achieve precise dosing.

Specifically, the discharge port 33 of the batching component 3 is in communication with the delivery line 2, as shown in FIG. It is shown that the solid material automatically dispensed by the batching component 3 enters the delivery line 2 through the discharge port 33. In a specific implementation, since the number of the ingredient parts 3 can be set according to the kind of the solid material that is automatically configured according to the need, the number of the discharge ports 33 communicating with the conveying line 2 can also be synchronously set according to the quantity of the ingredient parts 3. For example, when three kinds of solid materials need to be automatically configured, the batching parts can be set into three groups, and correspondingly, three sets of discharging ports are connected with the conveying line 2; or when five kinds of solid materials need to be automatically configured, the ingredients can be used. The components are set to 5 groups, and correspondingly 5 sets of discharge ports are connected to the delivery line 2. Preferably, an electromagnetic control valve may be disposed at the outlet of the discharge port 33 and the delivery line 2, and when the solid material is automatically configured, the electromagnetic valve is opened, so that the discharge port 33 communicates with the delivery line 2, The automatically configured material enters the delivery line 2 through the discharge port 33; when the automatic configuration of the material ends, the electromagnetic valve is closed, so that the discharge port 33 and the delivery line 2 are not connected, which can prevent the solid material from falling into the delivery when not being dispensed.

In order to ensure the rapid non-residual and high efficiency of the pneumatic conveying process, the inner wall of the conveying pipe 2 should be smooth and not easy to retain materials to ensure the speed and efficiency of transportation. Furthermore, the separating device 1 is in communication with the discharge opening 33 of the dosing member 3 via the transfer line 2, so that the length of the transfer line 2 can determine the distance separating the separating device 1 from the dosing member 3, which can be horizontally The distance may also be the distance in the vertical direction. Therefore, the separation device 1 and the dosing component 3 formed by the corresponding connection also have a certain horizontal and vertical distance, for example, the horizontal distance of the conveyance can be up to 30 meters, and the vertical distance of the conveyance can be Up to 10 meters, it can fully meet the user's requirements for the transport distance. This horizontal and vertical distance can be achieved by a smooth curved hose or by pipe bending of other materials. The material of the conveying pipe 2 may be various materials such as steel pipes, metal hoses, plastics, rubber, ceramics, and the like. The selection of the conveying line 2 takes into account the pressure and pressure of the conveying, the temperature and the influence of the conveying medium, and also considers the economics of the project. In the present invention, the length of the conveying pipe 2 can be arbitrarily set within a certain range, so that the batching component 3 does not need to be stacked together with the separating device 1, which saves the space of the cooktop and realizes the long-distance conveying of the material.

Specifically, the separation device 1 proposed by the present invention is a split separation device for decelerating and separating the gas and the solid material that are pneumatically conveyed by the delivery line 2, and is mainly composed of the separation body 11, the receiving member 12, and the row. The air pipe 13 and the connecting and disassembling component are composed, as shown in FIG. 3, The separation body 11 has a cylindrical inner wall which can be easily decelerated to separate the gas and the solid material, and the outer circumference of the separation body can be designed in various shapes such as a circular shape or a square shape. The exhaust pipe 13 is inserted into the top end of the separation body 11, and the depth in which the exhaust pipe 13 is inserted into the tip end of the separation body 11 differs depending on the solid material to be conveyed, the gas pressure, and the like. The exhaust pipe 13 can be used for intake air as well as for exhaust gas. For example, the exhaust pipe 13 can be supplied with negative pressure gas to realize the intake air in the separation device 1, and can also be used for discharging the gas decelerated and separated by the separation device 1. . The exhaust pipe 13 and the separation body 11 may be provided independently or integrally formed.

The separation body 11 is provided with an intake/feed port 111. Preferably, the intake/feed port 111 is a tangential inlet disposed in a tangential direction of the upper half of the separation body 11, and the first end 21 of the delivery line 2 is advanced. The gas/feed port 111 is in communication, and the gas and solid material pneumatically conveyed by the transfer line 2 can enter the separation device 1 through the first end 21 of the transfer line 2 and the intake/feed port 111.

The bottom end of the separating body 11 is butted or separated from the receiving member 12 by the connecting and detaching member, that is, when the pneumatic conveying material starts, that is, when the separating device operates, the receiving member 12 is docked to the bottom end of the separating body 11 by the connecting and detaching member. The gas and the solid material enter the separation device 1 through the delivery line 2, and the separation device 1 automatically separates the gas and the solid material, and the separated solid material falls on the receiving member 12 by its own gravity, and the separated gas passes through the exhaust pipe 13 After the pneumatic conveying material is finished, that is, after the separation device 1 is finished, the receiving member 12 is separated from the bottom end of the separating body 11 by the connecting and detaching member.

Preferably, in order to enable the correct alignment of the bottom end of the separating body 11 and the receiving member 12, a first limiting structure 112 is disposed at the bottom end of the separating body 11, as shown in FIG. 4, the first limit The shape and size of the structure 112 match the top end of the receiving member 12 and can be mated with the top end of the receiving member 12 to achieve proper alignment of the top end of the receiving member 12 with the bottom end of the separating body 11. In a specific implementation, the shape of the first limiting structure 112 may be different according to the shape of the top end of the receiving member 12, for example, when the top end of the receiving member 12 is circular, the first limiting structure 112 may be The shape-size matching U-shaped or circular structure, or when the receiving member is a square cup body, the first limiting structure 112 may be a square structure matching its shape and the like. Preferably, the receiving member 12 used in the present invention is a rounded cup-shaped cup whose bottom end is closed and whose top end is open. Therefore, the first limiting structure 112 is preferably a U-shaped structure.

Specifically, the receiving member 12 of the present invention is a receiving cup having a bottom end closed and a top opening. As shown in FIG. 5, the top end of the receiving member 12 can be connected to the bottom of the separating body 11 by the connecting and disassembling member. Docking or separating. The shape of the cup of the receiving member 12 may be cylindrical, prismatic, etc., and the inner wall thereof should be smooth and not easy to leave material. The preferred rounding of the present invention is The abutting cup body, after docking with the separating body 11, can facilitate the separation of the gas and the solid material, and can be separated from the separating body 11 to facilitate the pouring of the solid material. Preferably, a rim 121 protruding outward is provided at the top end of the receiving member 12 to facilitate the abutment of the receiving member 12 with the bottom end of the separating body 11.

The separating device 1 proposed by the invention is used for decelerating and separating the gas and the solid material conveyed by the conveying pipeline 2, so it is a gas-solid separation device, for example, a cyclone separator, or other gas solid materials can be separated. The apparatus of the present invention preferably uses a cyclone separator to achieve separation of the gas and the solid material, that is, a separation cylinder corresponding to the rounded-plate-shaped material receiving member 12 as a cyclone separator, and the connecting member 12 is docked to the connecting member through the connecting and disassembling member. When the bottom end of the main body 11 is separated, the separating body 11, the receiving member 12 and the exhaust pipe 13 constitute a complete cyclone, and the gas and solid materials can enter the separating body 11 through the conveying pipe 2 and the intake/feed port 111. In the gas-solid separator composed of the receiving member 12, the high-speed gas is rotated and decelerated in the separating device 1, the solid material is gravity-sinked, and finally falls into the receiving member 2, and the decelerated air is discharged by the exhaust pipe 13. .

In order to prevent the exhaust pipe 13 from discharging the solid material when it is exhausted, in the present invention, preferably, the filter 14 is disposed at one end of the exhaust pipe 13 that is inserted into the separation body 11, and the filter 14 can prevent the separation device 11 from being separated. The solid material is discharged through the exhaust pipe 13, and the density of the filter can be selected according to the type of the solid material.

In the present invention, the solid material dispensed by the batching component 3 is transported by pneumatic force in the conveying pipeline 2, and in specific implementation, it can be realized by means of negative pressure suction or positive pressure blowing. If a negative pressure is applied to the end of the exhaust pipe 13, the solid material dispensed by the dosing component 3 enters the separating device 1 through the conveying line 2 under the action of the negative pressure, and the gas is realized by the special structure of the separating device 1. Separation from the solid material; or a positive pressure may be introduced at the inlet 22 of the delivery line 2, and the solid material dispensed by the ingredient 3 can enter the separation device through the delivery line 2 under the positive pressure. Further, the deceleration separation is realized by the separating device 1.

Specifically, the manner in which the receiving member 12 and the bottom end of the separating body 11 are butted or separated is automatic or manual. In the automatic mode, the receiving member 12 is automatically docked to the bottom end of the separating body 11 by the connecting and detaching member, or the receiving member 12 is automatically separated from the bottom end of the separating body 11 by the connecting and detaching member; in the manual mode, the receiving member 12 passes The connection detaching member is manually butted to the bottom end of the separation body 11, or the splicing member 12 is manually separated from the bottom end of the separation body 11 by the connection detaching member. In the specific implementation, the connection and disassembly components of the present invention have various implementation manners. The following describes the automatic and manual modes by two specific embodiments. Bright.

Referring to FIG. 6 and FIG. 7 , respectively, the structure of the receiving member 12 and the separating body 11 is automatically separated or docked. In this embodiment, the connecting and disassembling components are implemented by the negative pressure driving device 4, specifically As shown in the drawing, the negative pressure driving device 4 is connected to one end of the exhaust pipe 13 that is not inserted into the separation body 11. At the beginning of the pneumatic conveying, the negative pressure driving device 4 is capable of generating a negative pressure which enters the separating device 1 through the exhaust pipe 13, and the pneumatic suction acts to suck the receiving member 12 facing the bottom end of the separating body 11, so that the receiving member 12 Forming a seal with the separating body 11, and the solid material dispensed by the compounding component 3 enters the separating device 1 through the conveying line 2 under the negative pressure generated by the vacuum driving device, and realizes the gas and solid materials through the special structure of the separating device 1. The separation, the solid material falls into the receiving part 12 of the separating device 1 after the gas-solid separation. After the end of the pneumatic conveying, the pneumatic force is stopped, the suction force disappears, and under the action of gravity, the receiving member 12 is disconnected from the separating body 11, and the receiving member 12 can be freely taken out to realize the discharging. In addition, during pneumatic conveying, the intake port 22 of the delivery line 2 can also enter the air to maintain air pressure balance.

In order for the receiving member 12 to be properly docked to the bottom end of the separating body 11, it should be ensured that the receiving member 12 is facing the bottom end of the separating body 11, and the vertical distance between the receiving member 12 and the separating body 11 is within a suitable range.

A second limiting structure 61 is disposed in the limiting device 6, the shape of the second limiting structure 61 is matched with the bottom end of the receiving member 12, and the second limiting structure 61 is opposite to the separating body 11. The bottom end, therefore, enables the correct positioning of the receiving member 12, i.e., by simply placing the receiving member 12 within the limiting structure 61, it is ensured that the receiving member 12 is facing the bottom end of the separating body 11. In addition, the vertical distance between the receiving member 12 and the separating body 11 can be further adjusted by adjusting the vertical distance between the limiting device 6 and the separating body 11, thereby ensuring an optimal pneumatic suction effect. The invention can reasonably set the limiting device 6 and the second limiting structure 61 at a certain position below the separating body 11 in advance, so that the user can simply place the receiving member 12 on the limiting device 6 when placing the receiving member 12. In the second limit structure 61, without correcting the correctness of the placement position, the correct alignment can be realized, and the convenience of the user is increased.

Referring to FIG. 9, the structure of the receiving member 12 and the separating body 11 is manually separated or butted. In this embodiment, the connecting and disassembling components are realized by using a magnetic device. Specifically, as shown in the drawing, the first magnetic device 51 is mounted on the contact surface where the separation body 11 and the receiving member 12 are butted, and the second magnetic device 52 is attached to the top end of the receiving member 12, the first magnetic device 51 and the first The two magnetic devices 52 have mutually attracting magnetic forces. When the receiving member 12 is placed at the bottom end of the separating body 11, the receiving member 12 is docked by the magnetic force between the first magnetic device 51 and the second magnetic device 52. Up to the bottom end of the separation body 11, the magnetic self-sealing effect is achieved. At this time, a positive pressure can be applied to the inlet 22 of the delivery line 2, and the solid material dispensed by the ingredient 3 can enter the separation device 1 through the delivery line 2 under the positive pressure, thereby passing through the separation device 1 The gas and the solid material are decelerated and separated; or the negative pressure is applied to the end of the exhaust pipe 13, so that the solid material dispensed by the batching component 3 enters the separating device through the conveying pipeline 2 under the action of the negative pressure. Further, the separation of the gas and the solid material is achieved by the special structure of the separation device 1. When the separation device 1 is finished and needs to be fed by the receiving member 12, the receiving member 12 can be directly separated and taken out, which can realize quick disassembly and convenient disassembly and assembly.

In a specific implementation, the first magnetic device 51 may be at least one magnetic steel or magnet attached to the contact surface of the separation body 11 and the receiving member 12, and the corresponding second magnetic device 52 is an iron ring attached to the top end of the receiving member 12, At least one magnet or magnetic steel; or the first magnetic device 51 may be a positive or negative device mounted on the contact surface of the separation body 11 and the receiving member 12, and the corresponding second magnetic device 52 is mounted on the receiving member 12. The negative electrode device or the positive electrode device at the top can attract each other to achieve the self-sealing effect of the magnetic force at the bottom end of the receiving member 12 and the separating body 11.

Preferably, the top end of the receiving member 12 is provided with an edge 121 protruding outward.
