Description

Technical Field

[0001] The utility model relates to silkworm cocoon processing equipment, in particular to a smokeless cocoon drying furnace. Background Art

[0002] Cocoon drying is an essential step in silkworm cocoon processing. Cocoon drying is the process of drying the purchased fresh cocoons into dry cocoons. The purpose is to use heat energy to kill the live silkworm pupae in the cocoon cavity of the fresh cocoon and remove an appropriate amount of moisture, to prevent the live pupae from hatching into moths and the parasitic fly eggs left by the silkworms during storage, and to prevent the maggots and pupa rot that damage the cocoon layer. At the same time, the heat treatment of the cocoon layer appropriately changes the soluble nature of the outer layer of sericin, enhances the resistance to cocoon boiling, protects the cocoon from easing, and is conducive to reeling and storage. At present, most cocoon drying uses a drying furnace with a combustion chamber plus a smoke channel. Smoke channels connected to the combustion chamber are distributed under the ground in the cocoon drying room. These smoke channels are connected to the smoke exhaust channels on the cocoon drying room. When in use, a cocoon cart loaded with silkworm cocoons is pushed into the cocoon drying room, and coal, firewood and other fuels are burned in the combustion chamber. The high-temperature smoke generated by the combustion dissipates heat through the smoke channel and the smoke exhaust channel, thereby drying and dehumidifying the silkworm cocoons in the cocoon drying room at high temperature, and the smoke is discharged into the air. This drying furnace is widely used in rural areas of silkworm cocoon breeding areas because of its low cost, easy construction and convenient operation. However, the drying furnace with the above structure is mostly suitable for fuels that produce a large amount of smoke after combustion. Due to the increasingly stringent requirements for environmental protection, in order to avoid polluting the environment, the use of such fuels that produce a large amount of smoke after combustion has been banned, and smokeless fuels that do not produce smoke, such as smokeless carbon or anthracite, are increasingly being promoted and used. The above drying furnace is suitable for burning fuels with smoke emissions but is not suitable for burning smokeless fuels that do not produce smoke. If the silkworm cocoons are dried through the above drying furnace by burning smokeless fuels, the drying efficiency and drying quality will be greatly affected. Therefore, there is an urgent need for a drying furnace that can be used for burning smokeless fuels that do not produce smoke to ensure the silkworm cocoon drying efficiency and drying quality. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide a smokeless cocoon drying furnace which can be suitable for burning smokeless fuel without generating smoke and can ensure the silkworm cocoon drying efficiency and drying quality.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a smokeless cocoon drying furnace, comprising a cocoon drying chamber provided with a chamber door, a combustion chamber for burning smokeless fuel provided on one side of the cocoon drying chamber, a heat dissipation channel provided in the cocoon drying chamber, a heat dissipation port provided at the inner end of the heat dissipation channel, the outer end of the heat dissipation channel is connected to the combustion chamber, a heat distribution device is provided in the cocoon drying chamber on the upper side of the heat dissipation channel, a discharge port is provided at the top of the cocoon drying chamber above the heat dissipation port, and a discharge regulating device is provided at the discharge port; cocoon car guide rails are respectively provided on both sides of the heat dissipation channel in the cocoon drying chamber.

[0005] As a preferred technical solution, the heat dissipation port includes a front heat dissipation port arranged at the inner end of the heat dissipation channel and an upper heat dissipation port arranged at the inner top of the heat dissipation channel, and a cover for opening and closing the upper heat dissipation port is arranged at the upper heat dissipation port.

[0006] As a preferred technical solution, the discharge adjustment device includes an adjustment plate rotatably installed at the discharge port through a rotating shaft, and one end of the rotating shaft extends to one side of the cocoon drying chamber and is connected to a rotating shaft rotation driving device.

[0008] As a preferred technical solution, the heat distribution device includes a pivot rotatably arranged above the heat dissipation channel, a plurality of heat distribution blades are axially mounted on the pivot, and one end of the pivot is drivingly connected to a heat distribution drive device.

[0009] The smokeless cocoon drying furnace adopts the above technical solution, comprises a cocoon drying chamber with a chamber door, a combustion chamber for burning smokeless fuel is arranged on one side of the cocoon drying chamber, a heat dissipation channel is arranged in the cocoon drying chamber, a heat dissipation port is arranged at the inner end of the heat dissipation channel, the outer end of the heat dissipation channel is connected to the combustion chamber, a heat distribution device is arranged on the upper side of the heat dissipation channel in the cocoon drying chamber, a discharge port is arranged at the top of the cocoon drying chamber above the heat dissipation port, and a discharge regulating device is arranged at the discharge port; cocoon car guide rails are arranged on both sides of the heat dissipation channel in the cocoon drying chamber. When using the utility model to dry cocoons, the cocoons are placed on the cocoon cart, and then the cocoon cart is pushed into the cocoon drying room and fixed on the cocoon cart guide rail. The cocoon drying room is closed and smokeless fuel is burned in the combustion chamber. Since the smokeless fuel burns without generating smoke, the high-temperature air heated by the smokeless fuel burns with a large amount of heat and enters the cocoon drying room through the heat dissipation channel. The heat is transferred to the cocoon drying room through the heat dissipation channel wall, the front heat dissipation port or the upper heat dissipation port. The heat is evenly distributed in the cocoon drying room by the heat distribution device to dry the cocoons on the cocoon cart, and the emission adjustment device controls the heat emission in the cocoon drying room to adjust the temperature and humidity, thereby ensuring the drying quality. The utility model is fully applicable to the burning of smokeless fuel that does not generate smoke to dry cocoons, and improves the drying efficiency and drying quality of cocoons.

DETAILED DESCRIPTION

[0015] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0016] like Figure 1 and 2 As shown, the smokeless cocoon drying furnace comprises a cocoon drying chamber 1 provided with a chamber door 3, a combustion chamber 5 for burning smokeless fuel is provided on one side of the cocoon drying chamber 1, and the smokeless fuel can be smokeless carbon or anthracite, etc. A heat dissipation channel 6 is provided in the cocoon drying chamber 1, and a heat dissipation port is provided at the inner end of the heat dissipation channel 6, and the outer end of the heat dissipation channel 6 is connected to the combustion chamber 5, a heat distribution device is provided on the upper side of the heat dissipation channel 6 in the cocoon drying chamber 1, a discharge port 7 is provided at the top of the cocoon drying chamber 1 above the heat dissipation port, and a discharge regulating device is provided at the discharge port 7; cocoon car guide rails 8 are provided on both sides of the heat dissipation channel 6 in the cocoon drying chamber 1. The cocoon drying chamber 1 can be built with cement and bricks. An operating room 4 is built on one side of the cocoon drying chamber 1 at the combustion chamber 5 for storing smokeless fuel and operating the combustion chamber 5 to add fuel. An inlet and outlet 2 is opened on the wall of the cocoon drying chamber 1 on the opposite side of the combustion chamber 5. A door 3 is provided on the inlet and outlet 2. Usually, each cocoon car guide rail 8 corresponds to an inlet and outlet 2 to facilitate the entry and exit of the cocoon car; the heat dissipation channel 6 can be built with cement and bricks, or it can be built with adobe or a prefabricated concrete pipe.

[0017] like Figure 1 and 2As shown, the heat dissipation outlet comprises a front heat dissipation outlet 9 provided at the inner end of the heat dissipation channel 6 and an upper heat dissipation outlet 10 provided at the inner top of the heat dissipation channel 6. A cover 11 for opening and closing the upper heat dissipation outlet 10 is provided at the upper heat dissipation outlet 10. Preferably, the exhaust outlet 7 is located above the upper heat dissipation outlet 10. Usually, when drying silk cocoons, only the front heat dissipation vents 9 are opened and the upper heat dissipation vents 10 are blocked. A part of the heat generated by the combustion of the smokeless fuel is transferred to the cocoon drying chamber 1 through the wall of the heat dissipation channel 6, and most of it is transferred to the cocoon drying chamber 1 through the front heat dissipation vents 9 at the end. Then, the heat is dispersed and distributed by the heat distribution device to dry the silk cocoons on the cocoon cart. After opening the upper heat dissipation vents 10, the heat is transferred to the cocoon drying chamber 1 through the wall of the heat dissipation channel and the front heat dissipation vents 9 because the hot air is light and therefore easy to rise. At the same time, most of the heat is transferred to the cocoon drying chamber 1 through the upper heat dissipation vents 10, which is convenient for the heat distribution device to distribute the heat. At this time, if the heat distribution device is controlled to stop working, the heat transferred to the cocoon drying chamber 1 by the upper heat dissipation vents 10 will rise and be discharged through the exhaust port 7, which is convenient for adjusting the temperature and humidity in the cocoon drying chamber 1.

[0018] like Figure 1-3As shown, the discharge adjustment device includes an adjustment plate 12 rotatably mounted at the discharge port 7 via a rotating shaft 13, one end of the rotating shaft 13 extends to one side of the cocoon drying chamber 1 or the operating chamber 4 and is connected to a rotating shaft rotation driving device. A hot air discharge channel 22 can be provided on the upper side of the discharge port 7, and a rain cover 23 is provided at the top outlet of the hot air discharge channel 22, which not only protects the discharge port 7, but also facilitates the discharge and adjustment of hot air and moisture in the cocoon drying chamber 1, and a suction fan can also be provided at the hot air discharge channel 22 to improve the discharge efficiency. The rotating shaft 13 is driven to rotate by the rotating shaft rotation driving device to drive the adjustment plate 12 to rotate, and the rotation angle of the adjustment plate 12 is controlled to adjust the opening and closing size of the discharge port 7, thereby adjusting the temperature and humidity in the cocoon drying chamber 1. The rotating shaft rotation driving device includes a rotating arm 14 fixedly mounted on the rotating shaft 13, a cable 15 connected to the outer end of the rotating arm 14, and a locking device 18 connected to the cable 15; a return arm 16 is also mounted on the rotating shaft 13, and a return spring 17 is connected between the return arm 16 and the cocoon drying chamber 1. The locking device 18 can be a two-way self-locking hand-cranked winch, and the two-way self-locking hand-cranked winch pulls and releases the cable 15 and the return spring 17 to drive the rotating shaft 13 to rotate and rotate, and drive the adjusting plate 12 to rotate to adjust the opening and closing size of the discharge port 7. The shaft rotation driving device can also use a motor to directly drive the shaft 13, and control the rotation of the shaft 13 by controlling the motor, or the shaft rotation driving device can also use an electric push rod to connect the rocker arm on the shaft 13, and control the rotation of the shaft 13 by controlling the electric push rod; similarly, the cover 11 set at the upper heat dissipation outlet 10 can be a cover plate that is buckled on the upper heat dissipation outlet 10, and the upper heat dissipation outlet 10 can be opened or closed by manual control; it can also be adopted that a flap is rotatably installed at the upper heat dissipation outlet 10 by a pin shaft, and the upper heat dissipation outlet 10 can be opened or closed by manually or by a driving device such as a motor, an electric push rod, etc. The control of the above-mentioned shaft rotation driving device and the cover 11 are both well-known structures and will not be described in detail here.

[0019] like Figure 1-3 As shown, the heat distribution device includes a pivot 19 rotatably arranged above the heat dissipation channel 6, and a plurality of heat distribution blades 20 are installed on the pivot 19 in an axially distributed manner, and one end of the pivot 19 is connected to a heat distribution drive device 21 in a transmission manner. The heat distribution drive device 21 can be connected to a speed change mechanism by a motor, and the speed change mechanism is connected to the pivot 19 in a transmission manner. The heat distribution drive device 21 drives the pivot 19 to rotate and drives the heat distribution blades 20 to rotate, and the heat transferred to the cocoon drying chamber 1 by the heat dissipation channel 6, the front heat dissipation outlet 9 and the upper heat dissipation outlet 10 is blown and distributed to various places in the cocoon drying chamber 1 to evenly dry the cocoons on the cocoon cart.

[0020] Temperature detectors and humidity detectors can be arranged in the cocoon drying room 1. The temperature detectors and humidity detectors can be set at the top of the cocoon drying room 1, and the temperature detectors and humidity detectors are connected to a display and a controller. The controller is connected to control the heat distribution drive device 21, the shaft rotation drive device and the various electrical components in the structure for controlling the cover 11, so as to improve the convenience of operation and control of the smokeless cocoon drying furnace.

[0021] like Figure 1 As shown, when drying cocoons, the cocoons are placed on the cocoon cart, the door 3 is opened, and then the cocoon cart is pushed into the cocoon drying chamber 1 and fixed on the cocoon cart guide rail 8, the door 3 is closed, and smokeless fuel is added to the combustion chamber 5 for combustion. Since no smoke is generated by the combustion of smokeless fuel, the high-temperature air heated by the combustion of the smokeless fuel carries a large amount of heat and enters the cocoon drying chamber 1 through the heat dissipation channel 6. The heat is transferred to the cocoon drying chamber 1 through the wall of the heat dissipation channel 6, the front heat dissipation port 9 or the upper heat dissipation port 10, and then the heat is evenly distributed to the cocoon drying chamber 1 by the heat distribution device to dry the cocoons on the cocoon cart. During the cocoon drying, the emission of heat and moisture in the cocoon drying chamber 1 is controlled by the emission regulating device to adjust the temperature and humidity to ensure the drying quality. Until the cocoon drying is completed, stop adding smokeless fuel to the combustion chamber 5, open the door 3 after the temperature in the cocoon drying chamber 1 drops, and push the cocoon cart out for cocoon collection and storage. Since smokeless fuel does not generate smoke when it is burned, the utility model adopts a heat dissipation channel 6 opened in the cocoon drying chamber 1 to directly discharge high-temperature air into the cocoon drying chamber 1 to dry the silk cocoons, which greatly improves the utilization rate of heat and the efficiency of cocoon drying. Unlike a cocoon drying furnace that burns fuel with smoke emissions, it is necessary to discharge the smoke generated by the combustion out of the cocoon drying chamber 1 through various smoke channels, and the smoke channels are tortuous and complicated in layout, which is not conducive to fuel combustion. In addition, the discharge of smoke will pollute the environment and a large amount of heat will be discharged from the cocoon drying chamber 1 along with the smoke, causing heat waste, making the cocoon drying efficiency low and also affecting the cocoon drying quality.
