Description

Technical Field

[0001] Embodiments of this disclosure relate to the field of evaporator technology, and more specifically, to an integrated spray film MVR evaporator. Background Technology

[0002] Evaporation and concentration are common processes in industrial production. MVR (Mechanical Vapor Recompression) evaporators are widely used in chemical, food, pharmaceutical and other fields due to their high efficiency and energy saving.

[0003] Traditional MVR evaporators have some shortcomings in structure and performance. For example, in terms of feed evaporation, the feed device design of some evaporators is not reasonable enough, which may lead to uneven feeding, affecting evaporation efficiency and product quality. The opening and closing structure of the feed port is not stable and reliable enough, and is prone to leakage problems. In the condensation stage, the existing condenser tube structure has certain limitations in improving the condensation effect, and there is a lack of effective auxiliary equipment to enhance condensation efficiency. Moreover, impurities can easily enter the condenser tube during use, affecting its normal operation and service life. In terms of support structure, the support devices of many evaporators are inconvenient to adjust and cannot adapt to different working environments and needs. The stability also needs to be improved. For example, when the evaporator needs to be installed on uneven ground or shakes during operation, it cannot be adjusted and fixed in a timely and effective manner, which may affect the normal operation of the equipment or even cause safety problems.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, the design of the opening shaft and the opening cone in conjunction with the closing cover and the closing port can achieve precise feeding control. When the opening shaft drives the opening cone to rise, the closing port opens, and the feed can enter the evaporator evenly and stably, avoiding the uneven feeding phenomenon that is easy to occur in traditional feeding devices, greatly improving the evaporation efficiency, while ensuring the stability of product quality and reducing product quality differences caused by feeding problems.

[0033] like Figures 1-4 As shown, it illustrates the integrated spray-film MVR evaporator of this disclosure, comprising:

[0034] Evaporator 1, with a collection tank 2 connected to one end of evaporator 1;

[0035] Feed evaporation assembly 3 is installed inside evaporator 1;

[0036] Support adjustment assembly 4 is provided at the bottom of evaporator 1;

[0037] The feeding evaporation assembly 3 includes a feeding hood 3-1, which is located on the upper end face of the evaporator 1. A mounting bracket 3-2 is provided on the inner side wall of the feeding hood 3-1. A positioning sleeve 3-3 is provided on the mounting bracket 3-2. An opening shaft 3-4 is inserted into the positioning sleeve 3-3. An opening cone 3-5 is provided at the lower end of the opening shaft 3-4. A closing cover 3-6 is provided at the inner bottom of the feeding hood 3-1. A closing opening 3-7 is provided on the closing cover 3-6. The bottom of the opening cone 3-5 is inserted into the closing cover 3-6. A condenser tube 3-8 is provided between the evaporator 1 and the collecting tank 2. A blower motor 3-9 is provided at the upper end of the condenser tube 3-8. The output end of the blower motor 3-9 is inserted into the condenser tube 3-8.

[0038] The support adjustment assembly 4 includes a support leg 4-1, which is located at the bottom of the evaporator 1. A movable pin 4-2 is inserted into the support leg 4-1, and a screw bolt 4-3 is inserted into the support leg 4-1. The screw bolt 4-3 is threadedly connected to the support leg 4-1.

[0039] In some examples, the feed hood 3-1 is installed on the upper end face of the evaporator 1. The feed hood 3-1 is connected to the extension tube 5. The extension tube 5 matches the bottom diameter of the feed hood 3-1 to ensure smooth feeding. The mounting bracket 3-2 is installed on the inner side wall of the feed hood 3-1. The positioning sleeve 3-3 is installed on the mounting bracket 3-2. The opening shaft 3-4 is inserted into the positioning sleeve 3-3, so that the opening cone 3-5 at the lower end of the opening shaft 3-4 is aligned with the closing opening 3-7 on the closing cover 3-6 at the bottom of the feed hood 3-1. The bottom of the opening cone 3-5 is inserted into the closing cover 3-6 to prepare for subsequent feeding.

[0040] Install a condenser tube 3-8 between the evaporator 1 and the collection tank 2. Fix the blower motor 3-9 to the condenser tube 3-8 with bolts. The side wall of the blower motor 3-9 is provided with positioning ribs 6 to ensure that the bottom of the positioning ribs 6 is fixedly connected to the condenser tube 3-8, so that the blower motor 3-9 is installed firmly. Install a filter screen 3-11 inside the condenser tube 3-8 to prevent impurities from entering. Install a positioning cover 3-12 and fit it on the output end of the blower motor 3-9. Install a blower blade 3-10 on the output end of the blower motor 3-9.

[0041] like Figures 1-4As shown, this embodiment proposes that a filter mesh 3-11 be provided inside the condenser tube 3-8, and a positioning cover 3-12 be provided inside the condenser tube 3-8. The positioning cover 3-12 is fitted onto the output end of the blower motor 3-9.

[0042] In some examples, filter mesh 3-11 is used to filter the gas flowing through condenser tube 3-8, and positioning cover 3-12 is used to position the blower 3-10.

[0043] For example, such as Figure 1 As shown, the support leg 4-1 has an arc-shaped curved structure. The bottom of the support leg 4-1 is provided with an anti-slip pad 4-4. There are several support legs 4-1, and multiple support legs 4-1 are evenly distributed at equal intervals at the bottom of the evaporator 1.

[0044] In some examples, anti-slip mat 4-4 is used to stabilize the position of evaporator 1.

[0045] For example, such as Figures 1-4 As shown, an extension pipe 5 is provided on the upper end face of the evaporator 1. The extension pipe 5 is connected to the feed hood 3-1. The feed hood 3-1 and the extension pipe 5 are connected. The bottom diameter of the extension pipe 5 matches that of the feed hood 3-1. The blower motor 3-9 is fixedly screwed onto the condenser pipe 3-8 by bolts. The side wall of the blower motor 3-9 is provided with a positioning rib 6. The bottom of the positioning rib 6 is fixedly connected to the condenser pipe 3-8. The side wall of the collection tank 2 is provided with a liquid outlet 7. The bottom of the collection tank 2 is provided with a support plate 8.

[0046] In some examples, the extension tube 5 is used to connect the feed hood 3-1, the positioning rib 6 is used to reinforce the blower motor 3-9, the liquid outlet 7 is used for the discharge of the collection tank 2, and the support plate 8 is used for the stable placement of the collection tank 2.

[0047] For example, such as Figure 1 As shown, the bottom of the evaporator 1 has a drive groove 9, the upper end of the support leg 4-1 is inserted into the drive groove 9, and the movable pin 4-2 is connected inside the drive groove 9.

[0048] In some examples, drive slot 9 is used to support the placement of leg 4-1.

[0049] For example, such as Figure 3 As shown, an extension shaft 10 is provided inside the condenser tube 3-8. The extension shaft 10 is located at the output end of the blower motor 3-9, and the lower end of the extension shaft 10 passes through the positioning cover 3-12.

[0050] In some examples, an extension shaft 10 is installed at the output end of the blower motor 3-9, so that the lower end of the extension shaft 10 passes through the positioning cover 3-12 to enhance the blowing effect.

[0051] After steam enters the condenser tube 3-8, the blower motor 3-9 is started. The output end of the blower motor 3-9 drives the blower blades 3-10 to rotate, accelerating the airflow and causing the steam to condense into liquid quickly in the condenser tube 3-8. The filter mesh 3-11 can filter impurities in the steam to ensure the purity of the condensed liquid. The positioning cover 3-12 and the extension shaft 10 work together to ensure the stable operation of the blower motor 3-9 and a good blowing effect.

[0052] The material enters the feed hood 3-1 through the extension tube 5. When the material reaches a certain amount, manually press the opening shaft 3-4 so that the opening cone 3-5 at the lower end of the opening shaft 3-4 is inserted into the closed hood 3-6. The material can then enter the evaporator 1 through the closed opening 3-7 for evaporation.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
