Description

Technical Field

[0001] This utility model relates to the field of equipment cleaning technology, and in particular to a cleaning tank for multiphase flow cleaning. Background Technology

[0002] Multiphase flow cleaning is a cleaning technique that utilizes the interaction of two or more fluids with different phases. It is commonly used in industrial applications to remove residues from production systems (such as pipelines and equipment). Multiphase flow cleaning is frequently employed in the cleaning of continuous fermentation sterilization equipment. This involves preparing a mixture of solid particles and liquid. The solid particles move at high speed in the liquid, abrading the cleaning surface. The liquid may contain cleaning agents or corrosives, which react chemically with the dirt, thus removing it.

[0003] A cleaning tank is also used in the process of cleaning the production system. After solid-liquid separation, the liquid enters the cleaning tank from the top of the mixture of solid particles and liquid to prepare for the next cycle of cleaning the production system.

[0004] In response to the above phenomena, although solid-liquid separation is performed on the mixed flow before the liquid enters the cleaning tank, it is inevitable that some solid particles will enter the cleaning tank, including small broken solid particles. These solid particles can easily cause blockage at the discharge port of the cleaning tank. Summary of the Invention

[0005] The purpose of this invention is to provide a cleaning tank for multiphase flow cleaning, which can filter mixed flow containing solid particles to reduce the phenomenon of solid particles flowing into the discharge port at the bottom of the cleaning tank.

[0006] This utility model provides a cleaning tank for multiphase flow cleaning, which adopts the following technical solution:

[0007] A cleaning tank for multiphase flow cleaning includes a tank body, a tank cover at the top of the tank body, and a feed inlet on the tank cover. It also includes...

[0008] A guide plate is horizontally positioned below the feed hole. The upper surface of the guide plate is arc-shaped, and a support is connected to the inner wall of the tank.

[0009] The filter screen is provided in multiple sets, and the multiple sets of filter screens are arranged in a ring array around the flow guide plate. The bottom end of the filter screen abuts against the flow guide plate and the support. The flow guide plate is provided with a partition for separating adjacent filter screens.

[0010] Preferably, the filter screen includes a vertical part and a bent part, the bent part is disposed on the circumferential inner wall at the bottom end of the vertical part, and the bent part and the vertical part form a groove;

[0011] The bent portion abuts against the bracket, and the end of the bent portion away from the vertical portion abuts against the end wall of the guide plate.

[0012] Preferably, the filter screen is provided with sealing nets at both ends of the groove along its length.

[0013] Preferably, a slider is provided on the side of the vertical part away from the guide plate, and a vertical groove is provided on the inner wall of the tank, the groove extending to the tank cover, and the slider is slidably connected to the groove in the vertical direction.

[0014] Preferably, the surface of the can lid has multiple sets of perforations for the filter screen to pass through, the perforations and the sliding groove are in communication, and the surface of the can lid is provided with a cover for sealing the perforations and the sliding groove, the cover being fixedly connected to the top of the filter screen.

[0015] Preferably, the guide plate has a mounting hole at its center, and a vertical sleeve is fixedly connected to the bottom surface of the can cover, with the bottom end of the sleeve abutting against the guide plate at the mounting hole.

[0016] Preferably, the center of the upper surface of the guide plate is higher than the edge of the guide plate.

[0017] Preferably, the support includes multiple sets of support rods arranged in a ring on the circumferential sidewall of the guide plate, with the end of each support rod away from the guide plate connected to the inner wall of the tank, and the multiple sets of support rods being inclined.

[0018] In summary, this utility model has the following beneficial technical effects:

[0019] 1. The tank body of this application is equipped with a guide plate and a filter screen. The guide plate is fixedly installed in the tank body by a bracket. Multiple sets of filter screens are arranged in a ring around the guide plate, and the bottom ends of the filter screens abut against the guide plate and the bracket respectively. A partition is provided between the multiple sets of filter screens. Since the guide plate is located below the feed hole and the upper surface of the guide plate is arc-shaped, when the mixed liquid containing solid particles enters the tank body from the feed hole, the mixed liquid flows to the guide plate and slides down the arc surface of the guide plate onto the filter screen. The liquid seeps down, while the solid particles are blocked on the filter screen, thereby reducing the phenomenon of solid particles falling to the bottom of the tank body.

[0020] 2. The filter screen in this application includes a vertical part and a bent part. The bent part is located at the bottom end of the vertical part, and the bent part and the vertical part form grooves for accumulating solid particles, thereby facilitating the recovery of solid particles.

[0026] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0027] This invention provides a cleaning tank for multiphase flow cleaning. (Refer to...) Figure 1 and Figure 2 A cleaning tank for multiphase flow cleaning includes a tank body 1, a guide plate 2, and a filter screen 3. The guide plate 2 and the filter screen 3 are both disposed inside the tank body 1. A tank cover 11 is provided at the top of the tank body 1, and the tank cover 11 has a feed hole 111. The guide plate 2 is placed horizontally below the feed hole 111, and a bracket 4 is fixedly connected to the guide plate 2 and the inner wall of the tank body 1. Multiple sets of filter screens 3 are arranged in a ring array around the guide plate 2, and the bottom end of the filter screen 3 abuts against the guide plate 2 and the bracket 4. That is, the bracket 4 and the guide plate 2 provide support for the filter screen 3. Multiple sets of partitions 21 for separating adjacent filter screens 3 are fixedly connected to the guide plate 2. That is, the two sides of each set of filter screens 3 abut against the wall of the partition 21, thereby preventing solid particles from leaking from the gap between two adjacent sets of filter screens 3.

[0028] Reference Figure 2 The upper surface of the guide plate 2 is arc-shaped. In this embodiment, the center of the upper surface of the guide plate 2 is higher than the edge of the guide plate 2. The mixed liquid flows onto the upper surface of the guide plate 2 and slides down the arc surface of the guide plate 2 onto the filter screen 3. The filter screen 3 intercepts solid particles in the mixed liquid. The support 4 in this embodiment includes multiple sets of support rods 41 arranged in a ring on the circumferential side wall of the guide plate 2. The multiple sets of support rods 41 are spaced apart to allow the liquid to flow smoothly to the bottom of the tank 1. The end of the support rod 41 away from the guide plate 2 is fixedly connected to the inner wall of the tank 1.

[0029] Reference Figure 1 and Figure 2 The filter screen 3 includes a vertical portion 31 and a bent portion 32. The bent portion 32 is fixedly connected to the circumferential inner wall at the bottom end of the vertical portion 31, that is, the bent portion 32 and the vertical portion 31 form a groove 33. The bent portion 32 abuts against the support 4. In this embodiment, the multiple sets of support rods 41 are in an inclined state, thereby increasing the contact area between the bent portion 32 and the support rods 41 and enhancing the stability of the filter screen 3. The end of the bent portion 32 away from the vertical portion 31 abuts against the end wall of the guide plate 2 to reduce the gap between the guide plate 2 and the bent portion 32, thereby preventing solid particles from leaking from between the bent portion 32 and the guide plate 2.

[0030] Reference Figure 2 and Figure 3 A slider 311 is fixedly connected to the side of the vertical part 31 opposite to the guide plate 2. A vertical groove 12 is opened on the inner wall of the tank body 1, extending through to the tank cover 11. The slider 311 is slidably connected in the groove 12 in the vertical direction, thus facilitating the disassembly and assembly of the filter screen 3. Multiple sets of perforations 112 for the filter screen 3 to pass through are opened on the surface of the tank cover 11. The perforations 112 and the groove 12 are in communication. A cap 113 is installed on the surface of the tank cover 11 to seal the perforations 112 and the groove 12, and the cap 113 is fixedly connected to the top of the filter screen 3. Workers can remove the cap 113 and take the filter screen 3 out of the tank body 1 without opening the tank cover 11, simplifying the disassembly and assembly steps of the filter screen 3. (Refer to...) Figure 1 The filter screen 3 is fixedly connected to the sealing net 34 at both ends of the groove 33 along its length, thereby preventing solid particles in the groove 33 from leaking from both sides of the groove 33 during the extraction of the filter screen 3.

[0031] Reference Figure 1 and Figure 2 The guide plate 2 has a mounting hole 22 at its center. In this embodiment, the guide plate 2 is suitable for a tank 1 with a spraying device and a stirring device. The mounting hole 22 provides space for the rotating shaft and spray pipe in the stirring device and the spraying device. The bottom end of the tank cover 11 is fixedly connected to the vertical sleeve 114. The bottom end of the sleeve 114 abuts against the guide plate 2 at the mounting hole 22. The sleeve 114 prevents solid particles from leaking from the mounting hole 22.

[0032] The implementation principle of the cleaning tank for multiphase flow cleaning according to this utility model is as follows:

[0033] When the mixture returns to the tank 1, it flows from the inlet 111 onto the guide plate 2 and then along the arc-shaped upper surface of the guide plate 2 to the groove 33 of the filter screen 3. The filter screen 3 intercepts solid particles. To remove the filter screen 3, disassemble and lift the cover 113 vertically upwards, allowing the filter screen 3 to slide out of the tank 1 through the perforation 112 to clean the solid particles on the filter screen 3. To install the filter screen 3, align the slider 311 fixed on the filter screen 3 with the groove 12 and slide the filter screen 3 vertically downwards until it abuts against the bracket 4. Then fix the cover plate to complete the installation of the filter screen 3. The tank 1 in this application intercepts solid particles, thereby reducing the phenomenon of solid particles clogging the discharge port at the bottom of the pipe.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
