Description

Technical Field

[0001] The invention relates to the technical field of mixing equipment, and in particular to a raw material mixing device and method for producing pig feed sweetener. Background Art

[0002] Pig feed sweetener is a sweetener specially used to be added to pig feed. After being added to pig feed, it can significantly increase the flavor of pig feed, increase the taste of pig feed when eaten, and increase the appetite of piglets. At present, some pig feed sweeteners are prepared using saccharin sodium, sweetness enhancers, spices, dietary fiber, and anti-caking agents as the main production raw materials. In the preparation process, saccharin sodium, sweetness enhancers, spices and deionized water are first mixed together in a certain proportion to obtain a mixed liquid, and then the mixed liquid is atomized and dispersed onto the dietary fiber through a multi-point spray gun on a fluidized bed, and then a solid material is obtained after heating and air drying. Finally, the solid material and the anti-caking agent are evenly mixed through a mixer to finally obtain the pig feed sweetener. In the above preparation process, corresponding solid-liquid mixing equipment is required to evenly mix saccharin sodium, sweetness enhancers, spices and deionized water.

[0003] Saccharin sodium, sweetness enhancers and spices are all powdered raw materials, and the solid-liquid mixing equipment in the prior art is usually only provided with a simple feeding hopper to feed the powdered raw materials. The powdered raw materials will scatter in the process of falling, resulting in a considerable portion of the powder being attached to the barrel wall of the mixing equipment, and a certain amount of powdered raw materials will also be attached to the inner wall of the feeding hopper. These attached powdered raw materials cannot be mixed with deionized water, which directly leads to a low utilization rate of the powdered raw materials. At the same time, it will also affect the accuracy of the proportion of each raw material in the final mixed liquid, especially after the materials with relatively small amounts are attached (for example, the amount of spices usually only accounts for 0.1%-1% of the total raw material mass), which will seriously affect the quality of the final mixed liquid.

[0004] Therefore, it is necessary to provide a raw material mixing device and method for producing pig feed sweetener to solve the above technical problems. Summary of the invention

By arranging a down-slide pipe at the bottom of a feeding hopper, the device can guide and block powder materials during the feeding process, effectively preventing the powder materials from being scattered around too much during the falling process, and greatly reducing the amount of powder materials adhering to the inner wall of a mixing barrel. By arranging components such as an annular tube, a plurality of first outer oblique tubes, a plurality of water spray boxes, a water tank, a micro water pump, and a water outlet hose, the device can extract the deionized water injected into the water tank in advance after the feeding is completed, and finally spray the deionized water to the inner wall of the feeding hopper through the plurality of water spray boxes to wash away the powder materials adhering to the feeding hopper.

The method for mixing raw materials for producing a pig feed sweetener can effectively prevent excessive scattering of powder materials to the surroundings during the feeding process by using the above-mentioned pig feed sweetener production raw material mixing equipment. By flushing the feeding hopper and the down chute with deionized water, the powder materials attached to the feeding hopper and the down chute can be flushed away and enter into a mixing barrel, which can effectively ensure the utilization rate of the powder materials and improve the accuracy of the proportions of the raw materials in the mixed liquid.

Splashing, an annular tube 18 is fixedly installed on the top inner wall of the cover 8, and a plurality of first outer oblique tubes 19 distributed in an annular shape are fixedly installed on the outer wall of the annular tube 18. A water spray box 20 is fixedly installed on one end of the plurality of first outer oblique tubes 19 away from the annular tube 18. A water spraying narrow opening 2001 is provided in the water spraying box 20. The water in the annular tube 18 is sprayed toward the inner wall of the hopper 6 through the water spraying narrow opening 2001. In order to improve the sealing degree between the cover 8 and the hopper 6, a docking ring 17 is fixedly installed on the bottom of the cover 8. An annular docking groove 1701 is provided at the bottom of the docking ring 17. The top of the hopper 6 extends into the annular docking groove 1701 and contacts with the top inner wall of the annular docking groove 1701. An electric push rod 16 is fixedly installed on the top of the moving seat 11. The electric push rod The output end of 16 is fixedly connected to the connecting plate 15.

When in use, a small amount of deionized water for mixing is injected into the water tank 22. When the powder is fed, the micro water pump 23 is started to pump out the deionized water in the water tank 22 and discharge it into the annular tube 18. Under the action of water pressure, the water in the annular tube 18 is finally sprayed out through the water spraying narrow openings 2001 of the multiple water spraying boxes 20 to flush the feeding hopper 6 and the lower chute 7. The powder attached to the inner wall of the feeding hopper 6 and the lower chute 7 can be washed away.

[0045] In this embodiment, in order to completely drain the deionized water in the water tank 22, a discharge pipe 26 is fixedly installed at the bottom of the water tank 22. The discharge pipe 26 extends away from the bottom end of the water tank 22 to the mixing barrel 1. A water valve is provided on the discharge pipe 26. After the powder is flushed, the water valve is opened to discharge a small amount of deionized water retained in the water tank 22 that cannot be pumped out by the micro water pump 23 into the mixing barrel 1.

[0046] In this embodiment, in order to facilitate observation of the mixing conditions of the materials in the mixing barrel 1 , an observation port is provided on the outer wall of the mixing barrel 1 , and a transparent glass is fixedly installed in the observation port.

[0047] In this embodiment:

[0048] In the initial state, the cover 8 and the feeding hopper 6 are in a misaligned state. When in use, first take a small portion of deionized water and inject it into the water tank 22, then open the cover plate on the water injection hopper 5, and inject the rest of the deionized water into the mixing barrel 1 through the water injection hopper 5, and then start the first motor 2 to run. The first motor 2 will drive the stirring rod 3 and the plurality of stirring blades 4 to rotate. After the first motor 2 is turned on, raw materials such as saccharin sodium, sweetness enhancer, and spices (hereinafter referred to as powder) are sequentially put into the feeding hopper 6, and the powder falls into the deionized water in the mixing barrel 1 along the down chute 7. The guide and barrier effect of the slide pipe 7 on the powder can effectively prevent the powder from scattering too much in the falling process, and can greatly reduce the amount of powder adhering to the inner wall of the mixing barrel 1. After the powder is put into the mixing barrel 1, the first motor 2 is started to drive the transverse screw 12 to rotate in the positive direction. The positively rotating transverse screw 12 will drive the moving seat 11 to gradually move toward the feeding hopper 6, and the moving seat 11 drives the two longitudinal slide bars 14, the sealing cover 8 and the like to move accordingly. When the sealing cover 8 moves to the top of the feeding hopper 6, the first motor 2 stops running, and then the electric push rod 16 is started. The output end retracts, the electric push rod 16 drives the connecting plate 15 to move downward, and the connecting plate 15 drives the sealing cover 8 to descend through the two longitudinal slide bars 14, and finally the docking ring 17 can be inserted into the feeding hopper 6 through the annular docking groove 1701, and then the micro water pump 23 is started to operate, and the micro water pump 23 extracts the deionized water in the water tank 22 through the pumping pipe 25, and discharges it into the annular pipe 18 through the water outlet hose 24. The deionized water in the annular pipe 18 is discharged into the multiple water spray boxes 20 through the multiple first outer inclined pipes 19. Under the action of water pressure, the deionized water passes through the multiple water spraying narrow openings 2001. The water is sprayed at a high speed toward the inner wall of the hopper 6. The sealing cover 8 and the docking ring 17 can effectively prevent water from splashing out. The sprayed material attached to the inner wall of the hopper 6 can be washed away and flow downward along the water flow. In the process of water flowing downward, the powder attached to the inner wall of the lower chute 7 will also be washed away and finally fall into the mixing barrel 1 and merge with the mixed liquid in the mixing barrel 1. Finally, the water valve on the discharge pipe 26 is opened to discharge the deionized water remaining in the water tank 22 into the mixing barrel 1. Finally, after the stirring time is sufficient, the first motor 2 is turned off, and then the material valve on the discharge pipe is opened to discharge the mixed liquid.

[0049] Compared with the related art, the raw material mixing equipment for producing pig feed sweetener provided by the present invention has the following beneficial effects:

[0050] By arranging a down pipe 7 at the bottom of the feeding hopper 6, the powder can be guided and blocked during the feeding process, which can effectively prevent the powder from scattering too much in the falling process, and greatly reduce the amount of powder adhering to the inner wall of the mixing barrel 1; by arranging the annular tube 18, multiple first outer inclined tubes 19, multiple water spray boxes 20, water tank 22, micro water pump 23, water outlet hose 24 and other components, the deionized water pre-injected into the water tank 22 can be extracted after the feeding is completed, and finally sprayed to the inner wall of the feeding hopper 6 through multiple water spray boxes 20, so as to wash away the powder attached to the feeding hopper 6. In the process of the water in the feeding hopper 6 flowing downward through the down pipe 7, The powder attached to the inner wall of the lower chute 7 will also be washed away and finally fall into the mixing barrel 1, which can effectively ensure the utilization rate of the powder and improve the accuracy of the proportion of each raw material in the mixed liquid; through the setting of the cover 8 and the docking ring 17, the water can be blocked during the process of flushing water into the feeding hopper 6, which can effectively avoid the deionized water from splashing out, and has the advantage of reliable use. Through the setting of two fixed seats 9, a horizontal slide bar 10, a movable seat 11, a horizontal screw 12, a second motor 13, two longitudinal slide bars 14, an electric push rod 16 and other components, when in use, the cover 8 can be automatically covered on the feeding hopper 6 or the cover 8 can be removed, which has the advantage of easy use.

[0051] Second embodiment:

[0052] The second embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0053] Please refer to Figure 7-Figure 9 In the raw material mixing equipment for producing sweetener for pig feed provided in the present embodiment, an extension tube 27 is slidably sleeved on the outer wall of the lower chute 7, and the extension tube 27 and the lower chute 7 constitute a "retractable lower chute". When in use, the length of the "retractable lower chute" can be adjusted according to the liquid level of deionized water, so that the bottom end of the "retractable lower chute" is kept at a small distance from the liquid level of deionized water, so that the powder can be better prevented from scattering around. An L-shaped support seat 29 is fixedly installed on the top of the mixing barrel 1, and a longitudinal screw 30 is penetrated and rotatably installed on the L-shaped support seat 29, and a lifting block 32 is threadedly sleeved on the longitudinal screw 30. A third motor 31 is fixedly installed on the top of the mixing barrel 1, and the output end of the third motor 31 is fixedly connected to the bottom end of the longitudinal screw 30. A lifting slide bar 28 is slidably installed on the top inner wall of the mixing barrel 1. The bottom end of the lifting slide bar 28 is integrally formed with an oblique connecting rod, and the bottom end of the oblique connecting rod is fixedly connected to the outer wall of the extension tube 27. The top end of the lifting slide bar 28 extends to the top of the mixing barrel 1 and is fixedly connected to the lifting block 32. The longitudinal screw 30 is driven by the third motor 31 to rotate forward or reverse, driving the extension tube 27 to descend or rise, so that the distance between the bottom end of the extension tube 27 and the deionized water surface can be adjusted.

[0054] In this embodiment, in order to limit the rising position of the lifting block 32 , a limiting end plate is fixedly installed on the top end of the longitudinal lead screw 30 .

[0055] In this embodiment:

[0056] In the initial state, the extension tube 27 is located at a relatively upper position. After deionized water is injected into the mixing barrel 1, the third motor 31 is started to drive the longitudinal screw 30 to rotate forward. The forward rotating longitudinal screw 30 drives the lifting block 32 to move downward. The lifting block 32 drives the extension tube 27 to move downward through the lifting slide bar 28. The position of the extension tube 27 is observed through the observation window. When the bottom end of the extension tube 27 is 5-10 cm away from the surface of the deionized water, the third motor 31 can be turned off. Since the bottom end of the extension tube 27 is relatively close to the deionized liquid surface at this time, the powder can be better prevented from scattering during the process of feeding the powder.

[0057] Through the arrangement of the extension tube 27, the lifting slide rod 28, the longitudinal screw 30, the third motor 31, the lifting block 32 and other components, the extension tube 27 and the lower chute 7 form a "retractable lower chute". After starting the third motor 31, the extension tube 27 can be driven to rise or fall, so that the bottom end of the "retractable lower chute" maintains a small distance from the liquid surface of the deionized water, which can better prevent the powder from scattering and further improve the accuracy of the proportion of each raw material in the mixed liquid.

[0058] Third embodiment:

[0059] The third embodiment of the present invention is further described below in conjunction with the accompanying drawings and implementation modes.

[0060] Please refer to Figure 10-13 In the raw material mixing equipment for producing pig feed sweeteners provided in the present embodiment, the two longitudinal slide bars 14 are also fixedly sleeved with the same fixing plate 33 located at the top of the cover 8, and the fixing plate 33 is fixedly connected to the cover 8, a heater 34 and a blower 35 are fixedly installed on the top of the cover 8, an exhaust pipe 36 is fixedly installed in the cover 8, the top of the exhaust pipe 36 extends to the outside of the cover 8 and is fixedly connected to the air outlet of the heater 34, the air outlet of the blower 35 is fixedly connected to the air inlet of the heater 34, the blower 35 is used to blow air into the heater 34, the heater 34 heats the air and then inputs it into the exhaust pipe 36, the hot air enters the mixing barrel 1 through the feeding hopper 6, the down chute 7, and the extension pipe 27, and the water originally retained in the feeding hopper 6, the down chute 7 and the extension pipe 27 can be dried, so that it will not affect the powder input during the subsequent preparation of the mixed liquid, and the dried water vapor is discharged through the water injection hopper 5.

[0061] In this embodiment, in order to speed up the drying speed of the inner wall of the feed hopper 6, the bottom end of the exhaust duct 36 is designed to be closed, and a plurality of second outer inclined tubes 37 distributed in a ring are fixedly installed on the outer wall of the exhaust duct 36 and near the bottom end. The bottom of each second outer inclined tube 37 faces the feed hopper 6. During heating, the hot air is sprayed toward the inner wall of the feed hopper 6 in advance, and then flows downward, which can increase the drying speed of the feed hopper 6.

[0062] In this embodiment, in order to pre-filter the air for drying, a filter cartridge 38 is fixedly installed at the air outlet of the blower 35. A filter cotton block 39 is arranged in the filter cartridge 38. The filter cotton block 39 is ceiling cotton with a filtration accuracy of 2-6μm.

[0063] In this embodiment, in order to facilitate the installation or removal of the filter cotton block 39, a mounting frame 40 is provided on the side of the filter cotton block 39 away from the blower 35, a hand rod is fixedly installed at the central position of the mounting frame 40, and a plurality of annularly distributed plug rods 41 are fixedly installed on the mounting frame 40. A plurality of annularly distributed alignment slots 3901 are opened on the outer ring of the filter cotton block 39, and the plurality of plug rods 41 are respectively located in the plurality of alignment slots 3901. When the mounting frame 40 is pulled outward by holding the hand rod, the filter cotton block 39 can be removed together. In the process of installing the filter cotton block 39 Since there are multiple insertion rods 41 for guidance, the filter cotton block 39 will not be squeezed and deformed, which facilitates the smooth insertion of the filter cotton block 39 into the filter cartridge 38. In order to prevent the filter cotton block 39 and the mounting frame 40 from slipping out, two blocking rods 42 are penetrated and slidably installed on the filter cartridge 38, and the mounting frame 40 is in contact with the two blocking rods 42. The top ends of the two blocking rods 42 are fixedly installed with the same arc-shaped connecting rod 43, and the top of the arc-shaped connecting rod 43 is fixedly installed with a lifting ring. By hooking the lifting ring and lifting the arc-shaped connecting rod 43 upwards, the two blocking rods 42 can be pulled out.

[0064] In this embodiment:

[0065] After the powder and deionized water are mixed and the mixed liquid is completely discharged, the cover on the water injection hopper 5 is opened first, and then the blower 35 and the heater 34 are started. The blower 35 sucks in the air from the external environment and discharges it into the heater 34. Before entering the blower 35, the air needs to pass through the filter cotton block 39, and the filter cotton block 39 will be intercepted by the dust in the air, so that the air entering the blower 35 is relatively clean. On this basis, the feed hopper 6, the lower chute 7, and the mixing barrel 1 will not be excessively contaminated by dust. After the air is heated in the heater 34, it is discharged to the inner wall of the feed hopper 6 through the multiple second outer oblique tubes 37 on the exhaust pipe 36. Then, under the action of wind pressure, the hot air will surge downward and pass through the lower chute 7 and the extension tube 27 in turn, so that the water retained in the feed hopper 6, the lower chute 7 and the extension tube 27 can be dried, and finally the air will be discharged through the water injection hopper 5;

[0066] When the filter cotton block 39 needs to be replaced, the arc-shaped connecting rod 43 is lifted upwards. Driven by the arc-shaped connecting rod 43, the two blocking rods 42 will be pulled out, so that the mounting frame 40 is not blocked. Then the mounting frame 40 is pulled out by holding the hand lever. When the mounting frame 40 is pulled out, the filter cotton block 39 will be taken out together. Then the filter cotton block 39 can be pulled out from the mounting frame 40. When installing a new filter cotton block 39, first install the filter cotton block 39 on the mounting frame 40. When installing, put the filter cotton block 39 The multiple alignment slots 3901 on the cotton block 39 are respectively aligned with the multiple insertion rods 41 on the mounting frame 40 and inserted into the mounting frame 40 until the front side of the filter cotton block 39 is in contact with the mounting frame 40, and then the multiple insertion rods 41 on the mounting frame 40 are inserted into the filter cartridge 38. Under the protection and guidance of the multiple insertion rods 41, the filter cotton block 39 will not be squeezed and will not be deformed, so the installation will be more convenient and smooth. After the mounting frame 40 is inserted into place, the two blocking rods 42 can be inserted.

[0067] By arranging the heater 34, the blower 35, the exhaust pipe 36, the plurality of second outer oblique pipes 37 and other components, the feed hopper 6, the down chute 7 and the extension pipe 27 can be heated, the retained water can be dried, and preparations can be made for the input of powder materials when the next raw material mixing operation is performed, which is beneficial to improving production efficiency; by arranging the filter cartridge 38 and the filter cotton block 39, the air used for heating can be pre-filtered to prevent the feed hopper 6, the down chute 7, the extension pipe 27 and the mixing barrel 1 from being contaminated by excessive dust, which is beneficial to maintaining the cleanliness of the raw material mixing equipment for the production of pig feed sweeteners; by arranging the mounting frame 40, the plurality of plug rods 41, the two baffle rods 42, the arc-shaped connecting rod 43 and other components, the user can quickly replace the filter cotton block 39, further improving the convenience of using the raw material mixing equipment for the production of pig feed sweeteners.

[0068] Fourth embodiment:

[0069] This embodiment provides a method for mixing raw materials for producing a pig feed sweetener, comprising the following steps:

[0070] T1: Take a small amount of deionized water and inject it into the water tank 22;

[0071] T2: Pour all the remaining deionized water into mixing barrel 1;

[0072] T3: Start the first motor 2 to stir the deionized water, and while stirring, add saccharin sodium, sweetness enhancer, and flavoring into the mixing barrel 1 through the feeding hopper 6 in sequence;

[0073] T4: First, the second motor 13 is started to move the cover 8 to the top of the hopper 6, and then the electric push rod 16 is started to move the cover 8 downward until the docking ring 17 at the bottom of the cover 8 is sleeved on the hopper 6;

[0074] T5: Start the micro water pump 23 to pump out the deionized water in the water tank 22 to flush the feeding hopper 6 and the downpipe 7;

[0075] T6: Open the water valve on the discharge pipe 26 at the bottom of the water tank 22 to discharge the deionized water remaining in the water tank 22 into the mixing barrel 1;

[0076] T7: After the mixing time is satisfied, the first motor 2 is turned off, and the mixed liquid is discharged.

[0077] The method for mixing raw materials for producing pig feed sweeteners can effectively prevent excessive scattering of powder during the feeding process by using the above-mentioned pig feed sweetener production raw material mixing equipment.
