Description

Technical Field

[0001] This utility model relates to the technical field of food processing equipment, specifically to a blocking-type snow melting machine with an upper water inlet structure. Background Technology

[0002] Existing snow melting machines generally employ open or simple gate designs for their feed inlets, primarily for liquid input. Common solutions include: straight-through feed channels without any obstructions; and feed inlets with sliding gates, opened and closed manually or electrically. These structures are significantly inadequate when handling slush-like materials. When the slush expands upon cooling within the refrigeration chamber, it easily overflows through the feed inlet, causing material waste and equipment contamination. While some improved designs incorporate mesh grilles, they still cannot effectively solve the overflow problem and negatively impact feeding efficiency.

[0003] Existing technologies suffer from the following main drawbacks: First, the open design cannot completely prevent the expansion and overflow of ice slush, resulting in a slippery working environment and high material loss rate. Second, while ordinary gate structures can physically block the flow, they completely obstruct the feeding channel when closed, making continuous feeding impossible. Third, although mesh grid designs allow some material to pass through, the pores are easily clogged by ice crystals, requiring frequent shutdowns for cleaning. Furthermore, existing structures do not consider the volume change characteristics of ice slush during expansion and lack a targeted pressure relief channel design, which is precisely the core problem this patent aims to solve. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a blocking type upper water inlet structure for snow melting machine, which has the advantage of preventing the ice sand inside the material cylinder from expanding and overflowing from the feed inlet, and solves the problem that the feed inlet is easily blocked by ice sand in the existing technology.

[0005] (II) Technical Solution: To achieve the above-mentioned purpose of preventing the ice and slush inside the cylinder from expanding and overflowing from the feed inlet, this utility model provides the following technical solution: a blocking-type upper water inlet structure for a snow melting machine, which is set at the upper end of the snow melting machine. The snow melting machine includes a cylinder and a feed inlet. The feed inlet is opened at the upper end of the cylinder. An evaporator and a stirrer are installed inside the cylinder. A discharge port is provided at one end of the cylinder. A feeding space is opened in the direction of the feed inlet toward the inside of the cylinder. A baffle is installed inside the feeding space. The two ends of the baffle are connected to the inside of the feeding space. At least two feeding holes are opened between the connection between the baffle and the feeding space. The feeding holes are oblong-shaped angled structures.

[0006] Preferably, the two ends of the baffle and the inner wall of the feeding space are integrally formed.

[0007] Preferably, a feed cover is provided at the upper end of the feed inlet, and the feed cover is connected to the outer surface of the material cylinder through a rotating shaft mechanism. The feed cover has the freedom to open and close along the rotating shaft mechanism.

[0008] Preferably, the edge of the feed inlet is provided with a slot, and the other end of the feed cover connected to the rotating shaft mechanism is provided with a locking block. The locking block is adapted to the slot, and the feed cover is fixed to cover the feed inlet by the locking block.

[0009] Preferably, a sealing strip is provided on the mating surface between the card block and the card slot.

[0010] Preferably, the inside of the feeding space has through openings on both sides except for the two sides connected to the baffle, and the hollowed-out portion connects the feeding space and the material cylinder.

[0011] Preferably, the baffle is an inclined structure, and the feed hole is opened at the connection between the baffle and the lower side of the feed space.

[0012] Preferably, the end of the baffle closest to the discharge port is higher.

[0013] Preferably, the rotating shaft mechanism includes at least two connecting brackets and a rotating shaft, the rotating shaft being rotatable about an axis inside the connecting brackets, and the rotating shaft being connected to the outer surface of the material cylinder through the connecting brackets.

[0014] (III) Beneficial Effects: Compared with the prior art, this utility model provides a blocking-type upper water inlet structure for a snow melting machine, which has the following beneficial effects: 1. The upper water inlet structure of this barrier-type snow melting machine, by setting a baffle at the feed inlet and opening the feed hole at the connection between the feed space and the baffle, makes the feed hole an elongated oval with a bend. The bend generates a vertically downward fluid shear force. Compared with the circular holes in the prior art, it can effectively guide the water flow into the inside of the barrel along a predetermined trajectory. In the prior art, when the liquid flows through the circular hole, the rising airflow below forms an air cushion at the circular hole. Due to the continuous curvature of the circular edge, the surface tension of the liquid is evenly distributed, which easily forms a closed liquid film. This affects the liquid falling and easily causes liquid residue. The barrel is equipped with an evaporator with a cooling effect. Under the cooling effect, the liquid residue in the circular hole is easy to condense and block. In this utility model, the shape of the hole is changed, so the continuity of the liquid film is interrupted, avoiding blockage caused by liquid residue.

[0015] 2. The upper water inlet structure of this barrier-type snow melting machine has openings on both sides, except for the two connecting ends of the baffle and the feeding space, to connect the feeding space and the inside of the cylinder. This creates a pressure balance channel, effectively regulating the pressure difference inside and outside the cylinder during the ice-making process. The design of opening the openings on the side forms a physical barrier, preventing the liquid inside the cylinder from condensing into ice slush under the action of the evaporator, which would then have a lower density and a larger volume, causing it to overflow from the feeding space.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-4The upper water inlet structure of the barrier-type snow melting machine is located at the top of the snow melting machine 1. In actual use, it can be designed at one end of the original discharge port 6 to ensure that the liquid entering from the inlet 3 can pass through the evaporator 4, ensuring the overall cooling effect. The snow melting machine 1 includes a barrel 2 and an inlet 3. The inlet 3 is located at the top of the barrel 2. The barrel 2 is equipped with an evaporator 4 and a stirrer 5. The discharge port 6 is located at one end of the barrel 2. The inlet 3 has a feeding space 31 extending into the barrel 2 to reduce the overall volume of the equipment. A baffle 32 is installed inside the feeding space 31. The two ends of the baffle 32 are connected to the inside of the feeding space 31. At least two feeding holes 33 are opened between the connection between the baffle 32 and the feeding space 31. The feed hole 33 is an oblong-shaped, angled structure. The angled edge generates a vertically downward fluid shear force. Compared with the circular holes in the prior art, it can effectively guide the water flow into the inside of the feed cylinder 2 along a predetermined trajectory. In the prior art, when the liquid flows through the circular hole, the rising airflow below forms an air cushion at the circular hole. Due to the continuous curvature of the circular edge, the surface tension of the liquid is evenly distributed, which easily forms a closed liquid film. This affects the liquid's fall and easily causes liquid residue. The feed cylinder 2 is equipped with an evaporator 4 with a cooling effect. Under the cooling effect, the liquid residue in the circular hole is easy to condense and block. In this utility model, the shape of the hole is changed, which interrupts the continuity of the liquid film and avoids blockage caused by liquid residue.

[0020] Please see Figure 2 and Figure 4 The baffle 32 and the inner wall of the feeding space 31 are integrally formed by processing, which increases the structural stability. The upper end of the feeding port 3 is provided with a feeding cover 7 to prevent dust from entering the inside of the material cylinder 2. The feeding cover 7 and the outer surface of the material cylinder 2 are connected by a rotating shaft mechanism 8. The feeding cover 7 has the freedom to open and close along the rotating shaft mechanism 8 and can be opened and closed freely through the rotating shaft 82. The edge of the feeding port 3 is provided with a slot 21. The other end of the feeding cover 7 connected to the rotating shaft mechanism 8 is provided with a locking block 71. The locking block 71 is adapted to the slot 21. The feeding cover 7 is fixed to cover the feeding port 3 by the locking block 71. The mating surface of the locking block 71 and the slot 21 is provided with a sealing strip 9 to ensure the sealing of the overall structure when the feeding cover 7 is closed.

[0021] Please see Figure 2Except for the two sides connected to the baffle 32, the other two sides of the feeding space 31 have through openings. The hollowed-out part connects the feeding space 31 and the material cylinder 2, establishing a pressure balance channel. This effectively regulates the pressure difference inside and outside the material cylinder 2 during the ice-making process. The design of opening the openings on the side forms a physical barrier, preventing the liquid inside the material cylinder 2 from condensing into slush under the action of the evaporator 4, causing the density to decrease and the volume to increase, thus preventing it from overflowing from the feeding space 31. The baffle 32 has an inclined structure, and the feeding hole 33 is opened at the connection between the baffle 32 and the lower side of the feeding space 31. The end of the baffle 32 near the discharge port 6 is higher, ensuring that the liquid poured into the feeding space 31 will enter the material cylinder 2 under the action of gravity and will not leave any residue.

[0022] Please see Figure 5 The rotating shaft mechanism 8 includes at least two connecting brackets 81 and a rotating shaft 82. The rotating shaft 82 can rotate around the axis inside the connecting brackets 81. The rotating shaft 82 is connected to the outer surface of the material cylinder 2 through the connecting brackets 81. In actual use, the connecting brackets 81 can be fixedly connected to the outer surface of the material cylinder 2 through welding or other processes. The rotating shaft 82 is designed as a detachable structure because the parts that are in frequent contact with liquid are more prone to damage, corrosion and rust. The convenient replaceable design can improve the overall service life of the equipment.

[0023] In summary, the upper water inlet structure of this barrier-type snow melting machine, compared to the circular holes in the prior art, can effectively guide the water flow into the inside of the material cylinder 2 along a predetermined trajectory. Furthermore, the hollowed-out part balances the air pressure, effectively regulating the pressure difference inside and outside the material cylinder 2 during the ice-making process. At the same time, the design of opening the opening on the side also forms a physical barrier, preventing the liquid inside the material cylinder 2 from condensing into ice slush under the action of the evaporator 4, causing the density to decrease, the volume to increase, and the overflow from the feeding space 31.
