Inspection door for mechanical equipment

Abstract

The invention discloses an inspection door for mechanical equipment. The door comprises a flange and a cover plate, an inspection port is formed in the center of the flange, the cover plate is arranged on the inspection port of the flange, and a sealing ring is arranged between the flange and the cover plate; a press rod is arranged on the cover plate and comprises an upper press rod body and a lower press rod body, the tail of the upper press rod and the tail of the lower press rod body are connected together, the cover plate is fixedly connected with the press rod through a middle connectionshaft, and the middle connection shaft penetrates through the portion between the upper press rod body and the lower press rod body; the end of the press rod is hinged to the flange through a movableshaft, and a manual switch device is arranged at the tail of the press rod; a step flange ring formed with the flange at a time is arranged at the outer circle of the flange, a 45-degree slope is arranged at the inspection port of an inner ring of the flange, the press rod is formed through edge folding of one-time formation, and the end of the upper press rod body, the end of the lower press rodbody and the movable shaft form a triangular strengthening structure. The inspection door is stable in structure, more convenient to operate and easy to clean. Sanitary dead corners are avoided, theinspection door better accords with the sanitation requirements, and hidden sanitation dangers are reduced to the greatest limit.

Description

technical field [0001] The invention relates to the technical field of food and chemical machinery, in particular to an inspection door for mechanical equipment with a stable structure, good sealing performance, easy cleaning, and no hygienic dead ends. Background technique [0002] Inspection doors are often used in the food and chemical industry. They are often used as entrances for welding and polishing in mechanical installations, and as maintenance ports for maintenance personnel to check the internal conditions of equipment and replace and maintain internal parts of equipment during equipment maintenance. The inspection door is usually closed during the operation of the equipment, and only needs to be opened or entered from here when the inside of the equipment needs to be maintained or the internal conditions of the equipment need to be checked. Therefore, the inspection door must adapt to the normal operation of the equipment under various working conditions, and can...

AI Technical Summary

Problems solved by technology

[0005] 1. In the process of opening or closing the inspection door, the rotation of the cover plate is realized by the axis a. The cover plate is fixed on the pressure rod d through the axis b and drives the switch of the cover plate h. The current shafts are all used A smooth rod and two sections are fixed with coils, so that the coils are easy to fall off and lost in actual operation, and once the coils are lost, the shaft is also easy to fall off

Because the inspection door is the passage to enter the equipment, the spring coil and shaft that fall off when the inspection door is opened and closed may fall into the inside of the equipment, which will cause problems with the equipment or pollute the product during the production process, or cause contamination in the product. foreign body

[0006] 2. The flange g is welded on the surface of the equipment, so in the welding process, since the surface of the general equipment is made of thin plates, the weld seam will be a 90-degree angle when the equipment is welded to the thick plate flange g Weld seam, which will increase the difficulty of welding, and the strength of such weld seam is relatively weak and it is easy to form a hygienic dead angle

[0007] 3. At present, the O-ring e and the flange surface g commonly used for sealing can easily form a sanitary dead angle, because the inner ring surface of the flange is flat at present, so the flange will form a 90-degree angle with the O-ring Therefore, during the cleaning process of the equipment, since the inspection door is closed, some foreign matter will exist in this 90-degree angle without being washed away by the water.

As a result, there are still foreign objects after the equipment is rinsed, and the inspection door must be opened for manual cleaning

[0008] 4. At present, the fastener of the inspection door is a screw with an outer hexagon. Therefore, it is necessary to bring a wrench when opening and closing the inspection door. The inspection door cannot be opened and closed by hand alone. Therefore, the operation Complicated and inconvenient to maintain

[0009] 5. The current pressure rod d is just a flat steel strip, which can easily cause the gland to be stressed unevenly during the process of fastening the inspection door, causing the upper and lower sides of the pressure rod to protrude outwards, resulting in poor sealing of the gland
