Description

Technical Field

[0001] The utility model relates to the technical field of thin film evaporators, in particular to a motor protective cover for a thin film evaporator. Background Art

[0002] High-efficiency rotary thin film evaporator is a new type of high-efficiency evaporator that can perform falling film evaporation under certain vacuum conditions by forming an "air knife" through the high-speed rotation of a fixed rotating scraper. It has a large heat transfer coefficient, high evaporation intensity, short and adjustable flow time, and is particularly suitable for evaporation and concentration of heat-sensitive materials and high-viscosity materials, as well as solvent removal.

[0003] Currently, thin-film evaporators are primarily used in sterile or cleanroom environments. These applications generally require that liquid-contacting metals be made of S31603 and non-contacting metals be made of S30408. Motors and reducers are primarily made of iron, and their exterior surfaces are then painted or spray-coated. Clearly, exposing the motor's exterior surface directly to a clean environment is inconsistent with applicable regulations. Furthermore, the motor's exterior surface is not sufficiently smooth and cannot be cleaned. Because the motor needs to dissipate heat, its surface requires a larger heat exchange surface, making it difficult to clean and more susceptible to dirt and grime. Paint peeling from the motor's exterior surface can also compromise the clean environment. Utility Model Content

[0004] The technical problem to be solved by the utility model is: the utility model provides a motor protective cover for a thin film evaporator, which isolates the motor from the external environment and isolates the carbon steel parts in a clean environment to prevent the carbon steel parts from contaminating the clean environment, thereby ensuring good heat dissipation effect of the motor and meeting design and usage requirements.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a motor protective cover for a thin film evaporator, comprising a protective cover body, the protective cover body covering the outside of the motor, a flange, a bearing box and an evaporation cylinder connected in sequence to the rear of the motor, the protective cover comprising an upper cover body and a lower cover body connected to each other, the upper cover body being arranged on the outside of the motor and the front end being connected to the flange, the lower cover body being arranged below the motor and sealing the bottom of the protective cover, a plurality of air inlets being provided on the left side surface of the upper cover body, and a plurality of air outlets being provided on the lower part of the right side surface of the lower cover body.

[0006] Furthermore, in order to ensure that the cold air can blow directly over the surface of the motor, the air inlet is located directly behind the motor, and the air inlet is a plurality of rectangular air inlets arranged in parallel.

[0007] Furthermore, in order to prevent impurities and dust from entering the interior of the protective cover through the air inlet, an air guide plate is provided on the upper cover body, and the air guide plate is located on the outside of the air inlet.

[0008] Furthermore, in order to enable the fan of the motor to blow out the internal hot air, the air outlet is located below the front end of the motor, and the fan of the motor blows the hot air out from the air outlet.

[0009] Furthermore, in order to facilitate the arrangement of the motor cables, the interior of the lower cover is detachably connected to a motor junction box, and a cable gland is provided on the lower cover for the cables to pass through the motor junction box.

[0010] Furthermore, in order to keep the interior of the protective cover body clean, a discharge port is provided below the lower cover body.

[0011] Furthermore, in order to facilitate the installation of the upper cover, an upper mounting hole is opened at the right end of the upper cover, and the upper cover is fixed to the outer ring of the flange through the mounting hole.

[0012] Furthermore, in order to securely connect the lower cover body and the upper cover body, the side portion of the lower cover body is connected to the upper cover body via a nut.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1.

[0024] like Figures 1 to 3 As shown, a motor protective cover of a thin film evaporator includes a protective cover body 1, which covers the outside of a motor 2. The rear of the motor 2 is connected with a flange 3, a bearing box 4 and an evaporation cylinder 5 in sequence.

[0025] The protective cover consists of an upper cover 11 and a lower cover 12. The upper cover 11 is positioned outside the motor 2 and connected to the flange 3 at its front end. The lower cover 12 is positioned below the motor 2 and blocks the bottom of the protective cover. The upper and lower covers 11, 12 have corresponding through-holes and are secured together using welding nuts or rivet nuts. An upper mounting hole 13 is defined at the right end of the upper cover 11. The upper cover 11 is secured to the outer ring of the flange 3 through this mounting hole. This allows for quick installation of the protective cover and flange 3, resulting in a simple and cost-effective installation structure.

[0026] The left side of the upper cover 11 is provided with a plurality of air inlets 14, which are located directly behind the motor 2. The air inlets 14 are arranged in parallel, rectangular rows. The lower right side of the lower cover 12 is provided with a plurality of air outlets 19. The air outlets 19 are located below the front end of the motor 2, and the fan of the motor 2 dissipates hot air through the air outlets 19. When the motor 2 is operating, the fan continuously rotates, and cool air enters from the rear air inlet 14. The cool air passes over the surface of the motor 2, carrying away the heat from the motor 2 and flowing toward the air outlets 19, thereby maintaining continuous heat dissipation and effectively cooling the motor 2.

[0027] The upper cover body 11 is provided with an air guide plate 15, which is located outside the air inlet 14. The air guide plate 15 can prevent most debris or dust from directly entering the air inlet 14, thereby preventing the interior of the protective cover from being contaminated.

[0028] A motor terminal box 16 is also located inside the lower housing 12. To facilitate wiring to the motor 2, this removable box is also installed. A cable gland 17 is provided on the lower housing 12 for routing cables through the box. The power cable and motor control cable for the motor 2 are connected to the motor 2 through separate cable glands 17.

[0029] A discharge port 18 is provided below the lower cover 12 , which can drain the accumulated water inside, especially in a humid environment, to avoid affecting the normal use of the motor.

[0030] In summary, the motor protective cover of the thin film evaporator of the utility model isolates the motor from the external environment and isolates the carbon steel parts in a clean environment to prevent the carbon steel parts from contaminating the clean environment, thereby ensuring good heat dissipation effect of the motor and meeting design and usage requirements.

[0031] The above description is based on the ideal embodiment of the present invention. Based on the above description, relevant personnel can make various changes and modifications without departing from the technical scope of this utility model.
