Description

Technical Field

[0001] The utility model relates to the technical field of stuffing boxes, in particular to a special tool for installing a stuffing box of a stripping kettle. Background Art

[0002] In a horizontal stripping kettle, the stuffing box is installed on both sides of the stripping kettle cylinder. The stuffing box assembly mainly consists of sealing components, stuffing, shaft sleeve, etc. The shaft sleeve rotates coaxially with the locating key on the shaft. The shaft sleeve and the shaft are sealed by three O-rings. The shaft sleeve and the stuffing box are sealed by static sealing components and stuffing. It is an important component of the horizontal stripping kettle.

[0003] During routine inspection and maintenance of the stuffing box, since the manufacturer does not provide special tools, the stuffing box needs to be installed through two threaded shoulders on the agitator shaft, each about 40 mm long. The matching length of the stuffing box sleeve and the shaft is about 600 mm long. During the assembly process, the maintenance personnel cannot control the concentricity of the stuffing box and the shaft when passing through the threaded shoulders. The adjustment time is too long, which can easily cut or break the three O-rings in the stuffing box sleeve.

[0004] The defects of the prior art are as follows: during the assembly process, the concentricity of the stuffing box and the shaft is difficult to control, so that the assembly quality cannot be guaranteed; the assembly operation takes a long time, which affects the assembly progress. Therefore, a special tool for installing the stuffing box of a stripping reactor is provided. Utility Model Content

[0015] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0016] Example: See Figure 1-2 The utility model provides a technical solution: a special tool for installing a stripping kettle stuffing box, comprising a protection tool and a stuffing box, the stuffing box comprising a first stuffing box 3, a second stuffing box 4, and a third stuffing box 5; the protection tool comprises a first stuffing box inner hole sealing ring protection tool 1, a second stuffing box inner hole sealing ring protection tool 2, the second stuffing box 4 and the third stuffing box 5 are assembled together through the second stuffing box inner hole sealing ring protection tool 2, and the first stuffing box 3 and the second stuffing box 4 are assembled together through the first stuffing box inner hole sealing ring protection tool 1.

[0017] The first stuffing box inner hole sealing ring protection tool 1 and the second stuffing box inner hole sealing ring protection tool 2 are conical.

[0018] The taper of the first stuffing box inner hole sealing ring protection tool 1 and the second stuffing box inner hole sealing ring protection tool 2 is 1:10.

[0019] The inner diameter of the bottom of the second stuffing box inner hole sealing ring protection tool 2 is larger than the outer diameter of the third stuffing box 5 , and the inner diameter of the top of the second stuffing box inner hole sealing ring protection tool 2 is 1 mm larger than the outer diameter of the second stuffing box 4 .

[0020] The inner diameter of the bottom of the sealing ring protection tool 1 of the inner hole of the first stuffing box is larger than the outer diameter of the second stuffing box 4 , and the inner diameter of the top of the sealing ring protection tool 1 of the inner hole of the first stuffing box is 1 mm larger than the outer diameter of the first stuffing box 3 .

[0021] Working principle: A special tool for installing the stripping kettle stuffing box. By making a special assembly tool, the assembly quality and assembly progress can be effectively controlled. It is safer, more accurate, more convenient and faster than the original assembly method. The specific implementation content is as follows:

[0022] Tools for making the inner hole sealing ring protection of the stuffing box:

[0023] Step 1: Measure the shoulder size of the threaded section about 40mm long at two locations on the agitator shaft to determine the fitting clearance at the installation position. During use, the inner hole size of the stuffing box sleeve and the agitator shaft size should meet the installation requirements.

[0024] Step 2: According to the measured size, select a steel plate with a thickness of 50mm (material: 45# steel) and use gas welding to cut the inner diameter separately outer diameter inner diameter outer diameter Two blanks of different sizes are processed on a lathe to produce two sleeves of the required size, and the taper of the two sleeves is made to be 1:10 to ensure that the sleeves have a certain degree of guidance, thus meeting the use requirements.

[0025] Installation of stuffing box:

[0026] Step 1: Lead the keyway on the agitator shaft outward along the axial direction and mark the installation position to ensure that when the stuffing box is installed in place, the keyway on the stuffing box sleeve is on the same line as the keyway on the shaft.

[0027] Step 2: Clean the surface of the shaft and install two tapered sleeves of different sizes at the two shaft shoulders. At this time, the outer circles of the two sleeves are consistent with the outer diameter of the shaft, so that the three O-rings in the inner hole of the stuffing box sleeve will not be cut or squeezed off. Slowly and evenly install the stuffing box in place.

[0028] Step 3: After the stuffing box is installed, remove the two special sleeves and proceed to the next maintenance process.

[0029] The above embodiments only express the implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
