Specific implementation

[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] Referring to Figures 1-3 The utility model provides an embodiment: energy -conserving evaporator of syrup evaporation concentration, including evaporating barrel 1, evaporating barrel 1 top fixedly connected with bidirectional motor 2, and the drive end of bidirectional motor 2 is all fixedly connected with rotating shaft 3, and the opposite end of rotating shaft 3 in front and back two sides is all fixedly connected with first bevel gear 4, and the outer wall of first bevel gear 4 is all engaged with second bevel gear 5, and the bottom of second bevel gear 5 is fixedly connected with rotating shaft 6 and screw rod 12 respectively, referring to Figure 4 The outer wall of rotating shaft 6 is rotatably connected to the inner wall of the top of evaporating barrel 1, the outer wall of rotating shaft 6 is fixedly connected with stirring plate 7, the inner wall of evaporating barrel 1 is fixedly connected with heating block 8 on both sides, the inner wall of the top of evaporating barrel 1 is fixedly connected with steam outlet pipe 9, the bottom of steam outlet pipe 9 is fixedly connected with annular pipe 10, the outer wall of annular pipe 10 is fixedly connected to the inner wall of evaporating barrel 1, the other end of annular pipe 10 is fixedly connected with steam exhaust pipe 11, the top of evaporating barrel 1 is fixedly connected with feed pipe 18, and the bottom of evaporating barrel 1 is fixedly connected with discharge pipe 19.

[0025] Specifically, the heating block 8 is internally provided with a heating wire. When an electric current passes through the heating wire, the heating wire generates heat. When the rotating shaft 6 rotates to drive the stirring plate 7 to rotate, the sugar syrup inside the evaporation barrel 1 is stirred, the contact area and frequency of the sugar syrup with the heating surface are increased, the heat is more uniformly and quickly transferred to the sugar syrup, thereby accelerating the evaporation of water, and the steam enters the annular pipe 10 through the steam outlet pipe 9. The annular pipe 10 is made of copper material, so that it has good heat conduction performance and can conduct heat in the steam to the evaporation barrel 1.

[0026] With reference to Figure 4 and Figure 5 , the outer wall of the screw rod 12 is threadedly connected with a threaded sleeve 13, the top end of the scraper 15 is fixedly connected to the bottom end of the threaded sleeve 13, the inner wall of the top end of the evaporation barrel 1 is fixedly connected with a sleeve 14, the outer wall of the threaded sleeve 13 is slidingly connected to the sleeve 14, the outer wall of the screw rod 12 is rotatably connected to the inner wall of the sleeve 14, the inner wall of the evaporation barrel 1 is fixedly connected with a sliding rod 16, the outer wall of the scraper 15 is slidingly connected to the outer wall of the sliding rod 16, notches 17 are formed in the left and right sides of the scraper 15, the notches 17 are matched with the shape of the heating block 8, and the scraper 15 is close to the inner wall of the evaporation barrel 1.

[0027] Specifically, the notches 17 are formed in the left and right sides of the scraper 15, and the positions of the notches 17 are perpendicular to the positions of the heating block 8. This makes the scraper 15 not be blocked by the heating block 8 when it is lowered. Meanwhile, the top end of the scraper 15 is concave, so that when the sugar syrup above the scraper 15 is scraped, the sugar syrup slides downward along the inclined surface on the scraper 15 and falls into the evaporation barrel 1. The outer wall of the discharge pipe 19 is provided with a control valve, which can control the opening and closing of the discharge pipe 19.

[0028] Working principle: when in use, the sugar syrup raw materials are added to the evaporation barrel 1 from the feeding pipe 18, and then the heating block 8 and the bidirectional motor 2 are started. The heating block 8 heats the sugar syrup raw materials in the evaporation barrel 1, the bidirectional motor 2 drives the rear measuring rotating shaft 3 to rotate, thereby driving the rear measuring first bevel gear 4 and second bevel gear 5 to rotate, so that the rotating shaft 6 rotates, and the rotating shaft 6 drives the stirring plate 7 to rotate to stir the sugar syrup, thereby accelerating the evaporation speed of water. The steam enters the steam outlet pipe 9 at the top, then enters the annular pipe 10 along the steam outlet pipe 9, the annular pipe 10 transfers the residual heat in the steam to the outer wall of the evaporation barrel 1, and finally is discharged from the steam discharge pipe 11. When the sugar syrup is evaporated, the bottom discharge pipe 19 is opened, the sugar syrup is discharged from the bottom discharge pipe 19, the bidirectional motor 2 is started to drive the front rotating shaft 3 to rotate, the front rotating shaft 3 drives the screw rod 12 to rotate through the first bevel gear 4 and the second bevel gear 5, the screw rod 12 drives the threaded sleeve 13 to move downward, the scraper 15 moves downward, and the residual sugar syrup in the evaporation barrel 1 is scraped away to reduce waste.
