Description

Technical Field

[0001] The invention relates to the technical field of filter cloth fixing devices, and in particular to an improved filter press assembled feed sleeve. Background Art

[0002] When filtering, the existing filter press generally installs filter cloth on both sides of the filter plate, and the filter cloth is mainly fixed to the filter plate by filter cloth clamps. The filter cloth clamp of the traditional filter press is threaded, and the injection molding production process of the thread is complex, the tolerance is large, and the production time is long. During high-pressure or high-speed filtration, the filter cloth clamp may loosen due to uneven force or vibration, causing the filter cloth to shift or fall off, thereby affecting the filtration effect. The clamping force of the filter cloth clamp needs to be moderate, both to ensure that the filter cloth is stable and does not fall off, and to avoid excessive clamping and damage to the filter cloth. However, in actual operation, the adjustment of the clamping force may be difficult and requires experienced operators to perform. The filter cloth clamp may accumulate material residues or dirt during use and requires regular cleaning and maintenance. However, due to the complex structure and large number of filter cloth clamps, the cleaning and maintenance costs may be relatively high. When the filter cloth needs to be replaced, the operator needs to spend a certain amount of time to disassemble and install the filter cloth clamp. If the design of the filter cloth clamp is not reasonable or the operation is not skilled enough, the time cost of replacing the filter cloth will increase. Summary of the invention

[0003] The purpose of the present invention is to provide an improved filter press assembled feed sleeve, which is easy to install in the mounting hole of the filter plate to fix the filter cloth, and is also easy to remove from the filter plate for regular cleaning and maintenance. The installation and disassembly are simple and convenient, reducing time waste; and the traditional threaded structure is abandoned, the processing difficulty is low, and the cost is reduced.

[0004] The technical solution adopted by the present invention is:

[0005] An embodiment of the present application provides an improved filter press assembled feed sleeve, comprising a limiting abutment ring and an installation ring sleeve, wherein a clamping plate is provided at the bottom of the limiting abutment ring extending downward, and an inclined portion is formed inwardly at the bottom of the clamping plate; the installation ring sleeve is embedded in the limiting abutment ring, and the outer wall of the installation ring sleeve abuts against the inner wall of the inclined portion and has an interference fit.

[0006] Furthermore, in some embodiments of the present invention, a groove is provided on the outward side of the inclined portion.

[0027] Example

[0028] Please refer to Figure 1-Figure 6 The present embodiment provides an improved filter press assembly feed sleeve, comprising a limit abutment ring 1 and a mounting sleeve 2. The limit abutment ring 1 has a clamping plate 3 extending downward from the bottom, and the bottom of the clamping plate 3 is formed inwardly to form an inclined portion 4; the mounting sleeve 2 is embedded in the limit abutment ring 1, and the outer wall of the mounting sleeve 2 abuts against the inner wall of the inclined portion 4 and has an interference fit. The filter press assembly feed sleeve is made of plastic material, which is easy to deform during installation and be clamped and fixed on the filter plate 7.

[0029] When actually installing, Figure 6 As shown, the clamping plate 3 is first inserted into the mounting hole 9 of the filter plate 7, the limiting abutting ring 1 abuts on the filter cloth 8 on the surface of the filter plate 7, and then the mounting ring sleeve 2 is inserted into the limiting abutting ring 1; since the bottom of the clamping plate 3 forms an inclined portion 4 facing inward, the inclined portion 4 is convenient for forming a guiding effect during installation, which is convenient for the clamping plate 3 to be embedded in the mounting hole 9; on the other hand, in the process of pressing the mounting ring sleeve 2 downward, the outer wall of the mounting ring sleeve 2 abuts against the inner wall of the inclined portion 4 and has an interference fit, so that the inclined portion 4 can be pushed outward through the outer wall of the mounting ring sleeve 2, so that it is convenient to push the clamping plate 3 outward through the mounting ring sleeve 2. Deformation, so that the outer wall of the clamping plate 3 can be deformed and tightly abutted and fixed with the filter plate 7, so that it is convenient to fix the filter press assembly feed sleeve as a whole on the filter plate 7 to clamp and fix the filter cloth 8. When disassembling, the mounting ring sleeve 2 can be directly pulled out to remove the filter press assembly feed sleeve as a whole. In this way, the improved filter press assembly feed sleeve provided by the present application is easy to be installed in the mounting hole 9 of the filter plate 7 to fix the filter cloth 8, and is also easy to be removed from the filter plate 7 for regular cleaning and maintenance. The installation and disassembly are simple and convenient, which reduces time waste; and it abandons the traditional threaded structure, has low processing difficulty, and reduces costs.

[0030] like Figure 1-Figure 6 As shown, in some embodiments of the present invention, a groove 5 is provided on the outward side of the inclined portion 4. The present invention provides the groove 5, so that a deformation space can be left through the groove 5, which facilitates the deformation of the inclined portion 4 toward the outer shape, thereby facilitating the installation of the entire feed sleeve of the filter press, and the material is not easy to crack during installation.

[0031] like Figure 1-Figure 6 As shown, in some embodiments of the present invention, the number of the clamping plates 3 is multiple and is evenly spaced along the circumference of the limiting abutting ring 1, and the clamping plates 3 are arc-shaped. The arc-shaped design facilitates increasing the abutment area between the outer side wall of the clamping plate 3 and the filter plate 7, thereby improving the stability of the clamping plate 3 clamped to the filter plate 7.

[0032] like Figure 1-Figure 6 As shown, in some embodiments of the present invention, an annular flange 6 is provided at the bottom of the limiting abutting ring 1. By providing the flange 6, the flange 6 can abut against the filter cloth 8 after the limiting abutting ring 1 is installed, which is convenient for installation.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic features of the present application.
