Description

Technical Field

[0001] The present invention relates to the technical field of steam distribution, and in particular to a steam distribution device with a heating function. Background Art

[0002] In modern animal husbandry, feed is a key factor in animal growth and production performance, and its quality and processing technology have attracted much attention. Feed is mainly composed of a variety of raw materials such as grains, soybean meal, minerals, vitamins, etc., and is scientifically formulated and finely processed to meet the nutritional needs of different animals at different growth stages. In the feed processing process, pelleting is a common process, which can improve the palatability of feed, reduce dust pollution, facilitate storage and transportation, and at the same time increase the feed intake and digestion and absorption rate of animals. In the feed pelleting process, in order to ensure the appropriate temperature and humidity of the feed raw materials, it is usually necessary to use a steam generator to pass steam into the mixing equipment. This process is crucial for starch gelatinization and protein denaturation, because starch gelatinization can cause starch granules to swell and rupture, thereby releasing more sugars, providing animals with a more digestible energy source, while protein denaturation helps to improve the binding force and stability of the feed, making the pelleted feed more solid and not easy to break.

[0003] However, in the existing technology, although steam plays an important role in the pelleting process, after pelleting, the pelleted feed needs to be dried to remove excess moisture and prevent the feed from becoming moldy and deteriorating. At present, the steam generated in the pelleting process has not been effectively reused after completing its main task. This phenomenon has caused a waste of steam energy. The existing technology also lacks equipment for distributing and utilizing steam and performing subsequent feed drying.

[0004] In order to solve the above problems, the present application proposes a steam distribution device with a heating function. Summary of the Invention

[0020] The above technical solution of the present invention has the following beneficial technical effects:

[0021] 1. The present invention heats steam through a heating component and then passes it into the shaft tube of the drying cylinder. The steam passes through the conical stirring member and the conical slapping member in sequence, enters the interlayer cavity, and then enters the discharge member through the distribution pipe for discharge. After the steam is introduced, the feed is transported to a first cavity of the drying cylinder and falls from above the conical stirring member. The driving member drives the conical stirring member to rotate the conical slapping member. The first cone disk of the conical stirring member disperses the feed from the center to the surrounding area and transfers heat to the feed. After the feed is dispersed, it enters the hopper. The stirring part stirs the feed and transfers heat to achieve a first-stage drying and heating. This process effectively disperses and heats the feed in the first cavity, increases its heated area, ensures uniform heat transfer, improves drying efficiency, and reduces drying time.

[0022] 2. When the feed passes through the hopper and enters the second-stage cavity, the second cone disk in the conical beating member can disperse the feed from the center to the surrounding area, and the second cone disk can also transfer heat to the feed. When the second cone disk rotates, it can beat the feed through the heat-conducting rod to reduce the agglomeration phenomenon and make the feed heated more evenly. When the feed falls to the bottom of the second-stage cavity, the stirring plate in the conical beating member can push the feed into the discharge member to complete the second-stage drying and heating of the feed. This two-stage drying and heating method further enhances the dispersion effect and heat transfer effect of the feed, so that the feed can be dried more evenly and fully in the second-stage cavity. By reducing the agglomeration of the feed, the problem of incomplete drying of the agglomerated part due to poor heat transfer is avoided, thereby improving the overall drying quality of the feed.

[0023] 3. When the steam passes through the conical beating piece and enters the interlayer cavity on the inner wall of the drying cylinder, the heat of the steam can fill the entire drying cylinder to improve the drying effect of the feed. The steam entering the interlayer cavity will enter the discharge piece along the distribution pipe. When the feed enters the discharge piece, it can fall on the discharge seat and then be discharged through the discharge port on the outer periphery of the discharge cover. The heat of the steam can be transferred to the feed in the falling process through the discharge seat, forming the final drying and heating of the feed. This final drying and heating method utilizes the waste heat of the steam to perform the final drying treatment on the feed, further reducing the moisture content of the feed and ensuring that the feed reaches the ideal degree of dryness when it is discharged from the drying cylinder. At the same time, this method of utilizing the waste heat of steam improves the utilization rate of steam energy and reduces energy waste. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0032] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present invention.

[0033] like Figure 1-7 As shown, the present invention provides a steam distribution device with heating function, comprising a drying cylinder 1 and a driving member 2;

[0034] The drying cylinder 1 is divided into a first chamber and a second chamber by a hopper 101. A vertically arranged shaft tube 102 is provided in the first chamber and is driven to rotate by a driving member 2. A heating component 3 is installed on the drying cylinder 1 to heat steam and pass it into the shaft tube 102. The bottom end of the shaft tube 102 is connected to a conical stirring member 4 located in the first chamber. The conical stirring member 4 is used to spread the material from the center to the surrounding area and stir it for heat conduction.

[0035] The bottom of the conical stirring member 4 is connected to a conical beating member 5 located in the second-stage cavity, and the conical beating member 5 is used to spread the material from the center to the surrounding area and beat it for heat conduction;

[0036] The inner wall of the drying cylinder 1 is integrally formed with an interlayer cavity 103, and the conical beating member 5 is rotatably engaged with the bottom wall of the drying cylinder 1, and the conical beating member 5 is in communication with the interlayer cavity 103;

[0037] A discharge piece 6 is installed at the bottom of the drying cylinder 1 for discharging the material and communicating with the second-stage cavity. The discharge piece 6 is connected to a distribution pipe 104 for communicating with the interlayer cavity 103 .

[0038] The present invention heats the collected steam through the heating component 3 and passes it into the shaft tube 102 in the drying cylinder 1. The steam passes through the conical stirring member 4 and the conical slapping member 5 in sequence and enters the interlayer cavity 103 on the inner wall of the drying cylinder 1. The steam can then enter the discharge member 6 along the distribution pipe 104 and finally be discharged through the discharge member 6. After the steam is introduced, the feed is transported to a cavity in the drying cylinder 1 and falls from the top of the conical stirring member 4. In this process, the driving member 2 drives the conical stirring member 4 to drive the conical slapping member 5 to rotate at the same time. When the conical stirring member 4 rotates, the material It diffuses from the center to the surroundings, and at the same time uses the steam heat conducted by the shaft tube 102 to stir and conduct heat to the material, thereby achieving preliminary drying and heating of the material. After being processed by the first cavity, the material passes through the hopper 101 and enters the second cavity. The conical flapping member 5 rotates to diffuse the material from the center to the surroundings again, and flaps and conducts heat to the material to further dry the material. After flowing in the conical flapping member 5, the steam enters the interlayer cavity 103. The steam heat in the interlayer cavity 103 can assist in drying the material in the drying cylinder 1. Finally, the steam enters the discharge member 6 through the distribution pipe 104, and the dried material is discharged through the discharge member 6.

[0039] In this embodiment, the conical stirring member 4 includes a first conical disk 41 and a stirring portion 42. The first conical disk 41 is connected to the bottom end of the shaft tube 102, and a first cavity communicating with the shaft tube 102 is defined in the first conical disk 41. The stirring portion 42 is connected to the bottom of the first conical disk 41 and is located in the hopper 101 for stirring and conducting heat to the material. The shaft tube 102 introduces heated steam into the first cavity of the first conical disk 41. The first conical disk 41 rotates under the drive of the shaft tube 102, and diffuses the material falling on its surface from the center to the surrounding area. At the same time, the heat of the steam in the first cavity is conducted to the material through the first conical disk 41, thereby preliminarily heating and drying the material and increasing the heated area of ​​the material. Subsequently, the material enters the hopper 101. The stirring portion 42 stirs the material in the hopper 101 while rotating with the first conical disk 41 to avoid material accumulation, and the stirring portion 42 conducts the heat of the steam to continuously heat and dry the material.

[0040] In this embodiment, the stirring portion 42 includes a first conduit 421, a ball 422 and a V-shaped tube 423. The bottom of the first cone disk 41 is connected to the first conduit 421 connected to the first cavity. The two balls 422 are arranged from top to bottom below the first conduit 421. The two ends of the two V-shaped tubes 423 are respectively connected to the two sides of the two balls 422. The ball 422 at the upper position is connected to the bottom end of the first conduit 421, and the conical beating member 5 is connected to the ball 422 at the lower position; the steam in the first cavity of the first cone disk 41 enters the upper ball 422 through the first conduit 421, and then passes through the V-shaped tube 4 23 flows into the lower ball 422, and driven by the shaft tube 102, the first conduit 421, the ball 422 and the V-shaped tube 423 rotate synchronously. When the V-shaped tube 423 rotates, the material in the hopper 101 is stirred to break up the material lumps, so that the material is heated more fully. At the same time, the steam heat is transferred to the material through the first conduit 421, the ball 422 and the V-shaped tube 423, and the material is continuously heated and dried. Multiple components transfer steam heat to improve heat utilization efficiency, ensuring that the material is continuously dried during the feeding process. The lower ball 422 introduces steam into the conical flapping member 5 and drives the conical flapping member 5 to rotate at the same time.

[0041] In this embodiment, the conical beating member 5 includes a second conduit 51 and a second conical disk 52. The second conduit 51 is connected to the sphere 422 at the lower position. The bottom end of the second conduit 51 is connected to the second conical disk 52 located in the second-section cavity. A second cavity connected to the second conduit 51 is provided in the second conical disk 52. A plurality of heat-conducting rods 521 arranged circumferentially and extending into the second cavity are connected to the second conical disk 52. The bottom of the second conical disk 52 is connected to a third conduit 53 connected to the second cavity. The third conduit 53 rotates with the bottom wall of the second-section cavity, and the third conduit 53 is connected to the interlayer cavity 103.

[0042] The lower ball 422 guides the steam into the second cavity of the second conical disk 52 through the second conduit 51. The second conical disk 52 rotates under the drive of the second conduit 51, and the material entering the second cavity is diffused from the center to the surrounding area. The heat of the steam in the second cavity is transferred to the material through the second conical disk 52, heating and drying the material. At the same time, the heat-conducting rod 521 on the second conical disk 52 rotates with the second conical disk 52, beating the material to break up the material lumps. The heat-conducting rod 521 transfers the heat of the steam in the second cavity to further heat the material. The steam in the second cavity enters the interlayer cavity 103 through the third conduit 53.

[0043] In this embodiment, an eccentrically arranged drop port 105 is provided at the bottom of the drying cylinder 1, and a stirring plate 54 is installed at the bottom end of the third conduit 53. The rotation path of the stirring plate 54 passes through the drop port 105 to push the material into the discharge piece 6; after the material accumulates at the bottom of the second-stage cavity, the third conduit 53 drives the stirring plate 54 to rotate, and the rotation path of the stirring plate 54 passes through the drop port 105, pushing the material at the bottom of the second-stage cavity toward the drop port 105, avoiding the accumulation of material at the bottom of the second-stage cavity, ensuring that the material smoothly enters the discharge piece 6, improving the material discharge efficiency, and ensuring the continuous and stable operation of the device.

[0044] In this embodiment, the discharge member 6 includes a discharge cover 61 and a discharge seat 62. The discharge cover 61 is installed at the bottom of the drying cylinder 1 and is connected to the blanking port 105. The discharge seat 62 is installed in the discharge cover 61, and the discharge seat 62 forms an inclined surface from the top to the bottom. The outer periphery of the discharge cover 61 is provided with a discharge port 63 located at the bottom of the inclined surface. A heat conduction cavity is provided in the discharge seat 62, and the distribution pipe 104 is connected to the heat conduction cavity. The outer periphery of the discharge seat 62 is connected to an exhaust pipe 64 connected to the heat conduction cavity, and a valve 65 is installed on the exhaust pipe 64; the material enters the discharge cover 61 through the blanking port 105 and falls on the inclined surface of the discharge seat 62. On the surface, it slides down the slope under the action of gravity to the discharge port 63 for discharge. At the same time, the steam in the interlayer cavity 103 enters the heat conduction cavity of the discharge seat 62 through the distribution pipe 104. The steam heat is conducted to the descending material through the discharge seat 62 to perform the final drying of the material. The waste gas generated during the drying process is discharged through the exhaust pipe 64. The valve 65 can control the switch and exhaust volume of the exhaust pipe 64. The above-mentioned use of the waste heat of steam to perform the final drying of the material further reduces the moisture content of the material and improves the drying quality. The inclined surface design facilitates the discharge of the material. The setting of the valve 65 can adjust the exhaust according to the actual situation to ensure the stability of the internal pressure of the device.

[0045] In this embodiment, the heating assembly 3 includes a rotary joint 31 and a heating part 32. The rotary joint 31 is installed at the top of the drying cylinder 1. The top end of the shaft tube 102 rotates through the top of the drying cylinder 1 and is connected to the rotating air outlet end of the rotary joint 31. The air inlet end of the rotary joint 31 is connected to the heating part 32 for heating the steam; the steam provided by the external steam source enters the heating part 32, and after the heating part 32 heats the steam, the steam is transported to the air inlet end of the rotary joint 31. Since the shaft tube 102 needs to rotate, the rotating air outlet end of the rotary joint 31 is connected to the top of the shaft tube 102. During the rotation of the shaft tube 102, the heated steam can be continuously introduced into the shaft tube 102 to provide a heat source for subsequent material drying.

[0046] In this embodiment, the heating part 32 includes a heating cylinder 321, an air supply pipe 322 and a steam pipe 323. The heating cylinder 321 is connected between the air supply pipe 322 and the steam pipe 323. The air supply pipe 322 is connected to the air inlet end of the rotary joint 31. A spiral heating pipe 324 is installed in the heating cylinder 321. External steam enters the heating cylinder 321 through the steam pipe 323. The spiral heating pipe 324 in the heating cylinder 321 is energized and heated to heat the steam in the heating cylinder 321 to maintain a certain amount of heat in the steam. The heated steam is transported to the air inlet end of the rotary joint 31 through the air supply pipe 322, and then introduced into the shaft tube 102 by the rotary joint 31. The design of the above-mentioned spiral heating pipe 324 can increase the contact area with the steam, making the steam heating more uniform and rapid, thereby ensuring the steam heating efficiency and temperature stability.

[0047] It should be noted that the external steam source can be a steam generator, or a steam generator that passes steam into the stirring device. It is only necessary to connect the pipe that discharges steam on the stirring device to the above-mentioned steam pipe 323.

[0048] In this embodiment, the driving member 2 includes a motor 21, a driving gear 22 and a driven gear 23. The driven gear 23 is fixedly mounted on the shaft tube 102 and is located between the drying cylinder 1 and the rotary joint 31. The motor 21 is installed on the top of the drying cylinder 1, and the output end of the motor 21 is connected to the driving gear 22 that meshes with the driven gear 23. After the motor 21 is started, the driven gear 23 is driven to rotate through the driving gear 22. Since the driven gear 23 is fixedly mounted on the shaft tube 102, the rotation of the driven gear 23 drives the shaft tube 102 to rotate, and the shaft tube 102 then drives the conical stirring member 4 and the conical beating member 5 to rotate synchronously.

[0049] In this embodiment, the top wall of the drying cylinder 1 is equipped with a material discharge hood 106 which is sleeved on the shaft tube 102, and the material discharge hood 106 is located above the first cone disk 41. The outer periphery of the material discharge hood 106 is connected to a material pipe 107, and the material pipe 107 is used to connect a screw conveyor; the screw conveyor conveys the material into the material discharge hood 106 through the material pipe 107. The material discharge hood 106 is sleeved on the shaft tube 102, which can prevent the material from falling directly on the shaft tube 102 and affecting the rotation of the shaft tube 102. At the same time, the material is evenly guided to the first cone disk 41 below, so that the material can fall evenly on the surface of the first cone disk 41, which is convenient for the first cone disk 41 to diffuse and heat and dry the material.

[0050] In a specific embodiment, the first cone disk 41 , the first conduit 421 , the ball 422 , the V-shaped tube 423 and the second cone disk 52 of the present invention are all made of aluminum alloy, which can provide good heat conduction.

[0051] The specific working principle of the present invention is as follows:

[0052] The screw conveyor conveys the material into the discharge hood 106 through the material pipe 107. The discharge hood 106 evenly guides the material to the surface of the first cone 41 to prevent the material from directly falling on the shaft tube 102 and affecting its rotation. External steam enters the heating cylinder 321 through the steam pipe 323. The spiral heating pipe 324 in the heating cylinder 321 is energized to heat the steam. The heated steam is then conveyed to the air inlet end of the rotary joint 31 through the air supply pipe 322. The rotary joint 31 then guides the steam into the shaft tube 102.

[0053] The motor 21 is started, and the driven gear 23 and the shaft tube 102 fixed thereon are driven to rotate through the driving gear 22, and the shaft tube 102 then drives the conical stirring member 4 and the conical beating member 5 to rotate synchronously;

[0054] The shaft tube 102 introduces steam into the first cavity of the first conical disk 41. The first conical disk 41 rotates to diffuse the surface material from the center to the periphery, while conducting the steam heat to initially heat and dry the material. After the material enters the hopper 101, the stirring portion 42 composed of the first conduit 421, the ball 422 and the V-shaped tube 423 rotates with the first conical disk 41, stirring the material and conducting the steam heat to continuously dry the material.

[0055] The lower ball 422 guides steam into the second cavity of the second conical disk 52 through the second conduit 51. The second conical disk 52 rotates to diffuse the material entering the second cavity, transferring the heat of the steam to heat and dry the material. The heat-conducting rod 521 beats the material as the second conical disk 52 rotates, breaking up lumps and transferring heat to further dry the material. The steam in the second cavity enters the interlayer cavity 103 through the third conduit 53. The heat of the steam in the interlayer cavity 103 assists in drying the material in the cylinder 1.

[0056] The third conduit 53 drives the stirring plate 54 to rotate, pushing the material at the bottom of the second chamber to the discharge port 105. The material enters the discharge cover 61 through the discharge port 105, slides down the inclined surface of the discharge seat 62 to the discharge port 63 for discharge, and the steam in the interlayer chamber 103 enters the heat conduction chamber of the discharge seat 62 through the distribution pipe 104, conducts heat and finally dries the sliding material. The exhaust gas generated in the process is discharged through the exhaust pipe 64 with a valve 65 to ensure the stability of the internal pressure of the device.

[0057] The above describes an embodiment of the present invention, but this embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Ordinary technicians in this field can also make many forms based on the inspiration of this embodiment, all of which are protected by this embodiment.
