Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a mixing equipment for fish, shrimp and crab feed additives. Background Technology

[0002] Feed is a general term for the food of animals raised by humans. In a narrower sense, feed mainly refers to the food of animals raised in agriculture or animal husbandry. When raising fish, shrimp and crabs, feed is required. Feed is a mixture of various substances.

[0003] Currently, a Chinese patent discloses a fish feed mixing device (authorization announcement number CN215743214U). This utility model includes: a mounting frame, on which a first mounting component and a second mounting component are movably mounted. A lifting device for changing the height of the mounting components is fixedly mounted on the upper outer surface of the mounting frame. The lifting device includes a motor and two sets of roller frames. This fish feed mixing device can change the height of the feeding component and the mixing drum, thereby facilitating the operator to place raw materials into the mixing drum. Feeding is convenient, meeting the space requirements below the mixing drum during feeding and unloading, resulting in better performance. It can directly scrape the raw materials from the inner surface of the mixing drum, making cleaning easier. However, the above method has the following drawbacks in actual use: during the mixing of raw materials, the materials are constantly stirred, generating heat. When adding active ingredients such as probiotics and enzymes, the high temperature will deactivate them, affecting feed preparation. Utility Model Content

[0004] Therefore, it is necessary to provide a fish, shrimp and crab feed additive mixing equipment to address the problem that the continuous stirring of raw materials generates heat, and that high temperatures can deactivate active ingredients such as probiotics and enzymes when they are added.

[0005] A mixing device for fish, shrimp, and crab feed additives includes: a mixing cylinder with symmetrically arranged support legs at its bottom; a cooling mechanism on the outside of the mixing cylinder for cooling and heat insulation; wherein the cooling mechanism includes a base fixedly connected to the bottom of the support legs, an outer cylinder fixedly connected to the top of the base, an evaporator on the top of the base, and the evaporator connected to an external refrigeration device via a connecting pipe; a cavity is provided between the mixing cylinder and the outer cylinder, and the cavity is filled with water; and a uniform cooling mechanism for uniformly cooling the mixing cylinder.

[0006] In one embodiment, both the inner walls of the outer cylinder and the base are filled with thermal insulation cotton, and the top of the outer cylinder is provided with an insulation cover plate with a feeding port.

[0007] In one embodiment, the mixing cylinder is an aluminum cylinder, and the centers of the mixing cylinder and the outer cylinder are on the same vertical line.

[0008] In one embodiment, the uniform mechanism includes a water pump fixedly connected to the top of the base, the water pump outlet being fixedly connected to an infusion pipe, and a water nozzle being fixedly installed at one end of the infusion pipe.

[0009] In one embodiment, a spiral blade descending in a spiral direction is fixedly connected inside the cavity, and the width of the spiral blade is the same as the thickness of the cavity.

[0010] In one embodiment, the infusion tube is vertically arranged, and the spiral blade has a through hole with the same diameter as the infusion tube, wherein the diameter of the infusion tube is smaller than the width of the spiral blade.

[0011] In one embodiment, the spiral blades are made of stainless steel, and the water pump inlet is provided with a filter plate;

[0012] In one embodiment, the evaporator is positioned at the center of the top of the base, and a gap is left between the top of the evaporator and the bottom of the mixing cylinder. Beneficial effects

[0013] A cooling mechanism is installed, which connects the evaporator to an external refrigeration unit. The evaporator cools the water in the cavity, and the water cools the inner wall of the mixing cylinder, thereby preventing the active ingredients from being deactivated due to the high temperature generated by the continuous stirring of the raw materials during mixing.

[0014] A water pump draws water from the bottom of the cavity to a higher position and sprays it out. The chilled water circulates down the outer wall of the mixing cylinder through spiral blades, cooling the mixing cylinder evenly and making the water flow, thus making the cooling more uniform.

[0027] The following is combined with Figures 1-4 This invention describes a mixing device for fish, shrimp, and crab feed additives.

[0028] In one embodiment, a fish, shrimp, and crab feed additive mixing device includes: a mixing cylinder 100, with supporting legs 110 symmetrically arranged at the bottom of the mixing cylinder 100, and a cooling mechanism 200 arranged on the outside of the mixing cylinder 100 for cooling and heat insulation of the mixing cylinder 100; wherein, the cooling mechanism 200 includes a base 211 fixedly connected to the bottom of the supporting legs 110, an outer cylinder 210 fixedly connected to the top of the base 211, an evaporator 220 arranged on the top of the base 211, and the evaporator 220 being connected to an external refrigeration device through a connecting pipe 221, and a cavity 212 is provided between the mixing cylinder 100 and the outer cylinder 210, the cavity 212 being filled with water; and a uniform cooling mechanism for uniformly cooling the mixing cylinder 100.

[0029] In this embodiment, the refrigerant enters the evaporator 220 through the connecting pipe 221, circulates and flows out, and cools the water in the outer cylinder 210 through the evaporator 220. After the water temperature drops, it absorbs the heat in the mixing cylinder 100, thereby cooling the raw materials in the mixing cylinder 100. This prevents the raw materials from getting too hot while they are being continuously stirred.

[0030] It should be noted that the refrigeration unit includes a compressor, condenser, dryer filter, capillary tube, etc. One end of the connecting pipe 221 is connected to the compressor, and the other end is connected to the capillary tube to create a sealed environment. The inside is filled with refrigerant, and the flow of refrigerant is used to cool the water in the outer cylinder 210.

[0031] A motor is installed at the center of the top of the mixing cylinder 100, and a stirring blade is fixedly connected to the output shaft of the motor. The raw materials in the mixing cylinder 100 are mixed and stirred by the rotation of the stirring blade.

[0032] like Figure 2 As shown, the inner walls of the outer cylinder 210 and the base 211 are filled with thermal insulation cotton, and the top of the outer cylinder 210 is provided with an insulation cover plate with a feeding port.

[0033] In this embodiment, thermal insulation cotton is used to reduce the loss of cold energy and decrease the heat exchange between the outer cylinder 210 and the air. A sealing cap corresponding to the feeding port is provided on the insulation cover plate.

[0034] It should be noted that the thermal insulation cotton is made of polyurethane foam, which has strong adhesion, is lightweight and high-strength, and has good thermal insulation performance.

[0035] like Figure 2 and Figure 3 As shown, the mixing cylinder 100 is an aluminum cylinder, and the center of the mixing cylinder 100 and the outer cylinder 210 are on the same vertical line.

[0036] In this embodiment, the aluminum cylinder has good thermal conductivity, which can quickly cool the raw materials in the mixing cylinder 100.

[0037] like Figure 2 and Figure 3 As shown, the uniform mechanism includes a water pump 300 fixedly connected to the top of the base 211, an infusion pipe 310 fixedly connected to the outlet of the water pump 300, and a water nozzle 311 fixedly installed at one end of the infusion pipe 310.

[0038] In this embodiment, the water pump 300 draws water from the bottom of the cavity 212 and sends it to the water outlet nozzle 311 through the infusion pipe 310. The water flows down the outer wall of the mixing cylinder 100 to achieve water circulation and keep the water temperature uniform.

[0039] like Figure 2 and Figure 3 As shown, a spiral blade 312 is fixedly connected inside the cavity 212, and the width of the spiral blade 312 is the same as the thickness of the cavity 212.

[0040] In this embodiment, after water is sprayed out from the water nozzle 311, it gradually flows down along the spiral blade 312 to cool the outer wall of the mixing cylinder 100. The spiral blade 312 increases the contact area between the water and the outer wall of the mixing cylinder 100, thereby improving the heat exchange effect.

[0041] like Figure 3 As shown, the infusion tube 310 is vertically arranged, and the spiral blade 312 has a through hole with the same diameter as the infusion tube 310. The diameter of the infusion tube 310 is smaller than the width of the spiral blade 312.

[0042] In this embodiment, the infusion pipe 310 does not affect the flow of water. Water is sent to a high place and flows down through the infusion pipe 310 to realize the circulation of water and improve the cooling uniformity of the mixing cylinder 100.

[0043] like Figure 2 As shown, the spiral blade 312 is made of stainless steel, and the water pump 300 inlet is equipped with a filter plate.

[0044] In this embodiment, the stainless steel blades have good corrosion resistance and a long service life. The filter plate is set to filter impurities in the water and protect the water pump 300.

[0045] like Figure 4 As shown, the evaporator 220 is located at the center of the top of the base 211, and there is a gap between the top of the evaporator 220 and the bottom of the mixing cylinder 100.

[0046] In this embodiment, the evaporator 220 is centrally located to cool the water at the bottom of the cavity 212, ensuring a uniform water temperature. The evaporator 220 does not contact the mixing cylinder 100 to prevent vibrations caused by mixing within the mixing cylinder 100 from damaging the evaporator 220.

[0047] Working principle: Raw materials are added to the mixing cylinder 100 for mixing. During mixing, the water in the cavity 212 is cooled by the evaporator 220, thereby cooling the mixing cylinder 100 and absorbing the heat generated during the mixing of raw materials, preventing the deactivation of feed active ingredients. The water at the bottom of the cavity 212 is pumped by the water pump 300 and sprayed out at the water outlet nozzle 311. The water flows spirally downward along the spiral blades 312, uniformly cooling the mixing cylinder 100. The water finally flows back to the bottom of the cavity 212, circulating continuously to achieve continuous cooling of the raw materials.

[0048] It should be noted that the evaporator 220 and spiral blade 312 mentioned above are all devices with relatively mature existing technology. The specific model can be selected according to actual needs.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
