Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and more specifically, it relates to a high-pressure cleaning device for papermaking felt. Background Technology

[0002] Papermaking felt is an indispensable and crucial component of papermaking machines, playing a vital role in the papermaking process. It is typically woven from special fiber materials, possessing excellent air permeability, water absorption, and abrasion resistance. In the forming section of the papermaking machine, the felt supports and transports pulp fibers, helping the pulp form a uniform paper structure during dewatering. Its air permeability ensures rapid drainage of water from the pulp, while its water absorption absorbs excess moisture, preventing the paper from becoming overly wet. Simultaneously, its abrasion resistance ensures the felt is not easily damaged during prolonged operation, extending its service life. The quality of the papermaking felt directly affects the quality of the paper and production efficiency. High-quality papermaking felt improves the smoothness, strength, and appearance of the paper, making it an indispensable key material in the modern papermaking industry.

[0003] Regular cleaning can effectively extend the service life of felt. Most existing methods use high-pressure nozzles to clean felt, but the cleaning water is not drained from the felt in time after cleaning, resulting in some pulp fibers and other impurities remaining on the felt, resulting in poor cleaning effect. In addition, excessive water on the felt will increase the energy consumption of the subsequent drying stage and make dehydration difficult. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a high-pressure cleaning device for papermaking felt.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure cleaning device for papermaking felt, comprising linear modules spaced apart on one side of the felt, a base fixedly connected to the slider of the linear modules, a cleaning box mounted on the base, a cleaning port on the side of the cleaning box near the felt, a bracket fixedly connected inside the cleaning box, multiple nozzles mounted on the bracket, the nozzles of the multiple nozzles all facing the felt, a water supply pipe connected to the end of the multiple nozzles away from the felt, the multiple water supply pipes all passing through the cleaning box, a squeezing roller rotatably connected inside the cleaning box, the squeezing roller abutting against the felt, and the squeezing roller being located below the nozzles of the multiple nozzles.

[0006] Preferably, the lower end of the cleaning tank is connected to a drain pipe.

[0007] Preferably, an electric cylinder is installed on the base, the piston rod of the electric cylinder passes through the base and is fixedly connected to the cleaning tank, and multiple guide rods are fixedly connected to the cleaning tank, all of which are slidably connected to the base.

[0008] Preferably, a scraper is fixedly connected inside the cleaning tank, and the scraper rubs against the extrusion roller.

[0009] Preferably, a blocking roller is rotatably connected inside the cleaning tank, the blocking roller abuts against the felt, and the blocking roller is located above the nozzles of multiple spray heads.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The water jet from the nozzle passes through the cleaning port and washes the running felt. Most of the water splashes back into the cleaning tank, while the rest is absorbed by the felt. The water inside the felt is squeezed out by the squeeze roller, and the residual pulp fibers and other impurities fall into the cleaning tank along with the squeezed water, resulting in better cleaning effect and effectively reducing energy consumption in the subsequent drying section.

[0012] 2. Before the cleaning box is moved by the linear module, the electric cylinder is used to move the cleaning box away from the felt to avoid damaging the felt. After the cleaning box is moved to the designated position, the electric cylinder is used to move the cleaning box closer to the felt, so that the squeezing roller comes into contact with the felt.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Reference Figures 1 to 3 This utility model provides a technical solution: a high-pressure cleaning device for papermaking felt, including a linear module 1, wherein the linear module 1 is spaced apart on one side of the felt, and a base 2 is fixedly connected to the slider of the linear module 1, such as... Figure 1 The linear module 1 drives the base 2 to reciprocate. A cleaning tank 3 is mounted on the base 2. A cleaning port 4 is opened on the side of the cleaning tank 3 closest to the felt. A bracket 5 is fixedly connected inside the cleaning tank 3. Multiple nozzles 6 are mounted on the bracket 5, which supports the nozzles 6. The nozzles of all nozzles 6 face the felt. Water supply pipes 7 are connected to the ends of the nozzles 6 furthest from the felt, and all water supply pipes 7 pass through the cleaning tank 3. Figure 3The end of the water supply pipe 7 away from the nozzle 6 is connected to an external water pump, so that the cloth can be washed through the nozzle 6. The inside of the cleaning box 3 is rotatably connected to the squeezing roller 8, which abuts against the cloth. The squeezing roller 8 is located below the nozzles of the multiple nozzles 6.

[0023] like Figure 2 and Figure 3 The water jet from nozzle 6 passes through cleaning port 4 and washes the running felt. Most of the water splashes back into cleaning tank 3, while the rest is absorbed by the felt. The water inside the felt can be squeezed out by squeezing roller 8, and residual pulp fibers and other impurities can fall into cleaning tank 3 along with the squeezed water, resulting in better cleaning effect and effectively reducing energy consumption in the subsequent drying section.

[0024] The linear module 1 drives the base 2 to move back and forth, and the base 2 drives the cleaning box 3 to move back and forth, thus cleaning the entire felt.

[0025] Specifically, the lower end of the cleaning tank 3 is connected to a drain pipe 9, and the cleaning water that falls into the cleaning tank 3 is discharged through the drain pipe 9.

[0026] Specifically, an electric cylinder 10 is installed on the base 2. The piston rod of the electric cylinder 10 passes through the base 2 and is fixedly connected to the cleaning tank 3. A plurality of guide rods 11 are fixedly connected to the cleaning tank 3, and the plurality of guide rods 11 are slidably connected to the base 2.

[0027] like Figure 1 and Figure 2 The base 2 supports the cleaning box 3 through multiple guide rods 11, and the electric cylinder 10 can move the cleaning box 3 away from or closer to the cloth.

[0028] Before the cleaning box 3 is moved by the linear module 1, the electric cylinder 10 moves the cleaning box 3 away from the felt to avoid damaging the felt. After the cleaning box 3 moves to the designated position, the electric cylinder 10 moves the cleaning box 3 closer to the felt, so that the squeezing roller 8 comes into contact with the felt.

[0029] Specifically, a scraper 12 is fixedly connected inside the cleaning tank 3, and the scraper 12 rubs against the extrusion roller 8, such as... Figure 3 The scraper 12 can scrape off the water on the squeezing roller 8, preventing the rotating squeezing roller 8 from splashing the water back onto the felt.

[0030] Specifically, a blocking roller 13 is rotatably connected inside the cleaning tank 3. The blocking roller 13 abuts against the felt and is located above the nozzles of the plurality of nozzles 6.

[0031] like Figure 3The blocking roller 13 can block the upward splashing water flow and prevent water from splashing out through the gap between the washing box 3 and the felt.

[0032] Working principle: The water jet from nozzle 6 passes through the cleaning port 4 and washes the running fabric. Most of the water splashes back into the cleaning tank 3, while the remaining water is absorbed by the fabric. The water inside the fabric can be squeezed out by the squeeze roller 8, and the residual pulp fibers and other impurities can fall into the cleaning tank 3 along with the squeezed water.

[0033] The linear module 1 drives the base 2 to move back and forth, and the base 2 drives the cleaning box 3 to move back and forth, thus cleaning the entire felt.

[0034] It should be noted that all electrical components appearing in this application are connected to an external main controller and 220V AC mains power. The main controller can be a processor, alarm module, or drive module, etc., to control conventional known devices. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as bolts, rivets, and welding, which are mature in the prior art. The machinery, parts, and equipment all adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.
