Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a tank bottom filter. Background Art

[0002] At present, the operating conditions of PTA oxidation solvent stripping towers are generally poor. Because the pipes and the inner walls of the pipes are prone to wall formation, a lot of material accumulates at the bottom of the tank after a period of operation, resulting in limited flow of the pump inlet angle valve at the bottom of the tank, causing pump cavitation vibration. In addition, because the accumulated material is located inside the tank, measures such as pumping alkali backwashing are not effective, resulting in a short stable operation cycle of the solvent stripping tower system. It needs to be taken offline for alkali washing separately every few months, resulting in high material consumption, and the circulating pump at the bottom of the tank is easily damaged due to frequent cavitation.

[0003] The applicant solves the above technical problems by adding a bottom filter to the existing chemical equipment.

[0004] A tank filter is a device commonly used at the bottom of various tanks and containers to filter liquids within. The liquid to be filtered enters the filter through the inlet under the influence of gravity or external pressure (such as pump pressure). As the liquid flows through the filter element, solid impurities are trapped on the surface or inside the filter element (depending on the type of filter element), while clean liquid is able to pass through the filter element and exit through the outlet, thus achieving the purpose of filtering and purifying the liquid within the tank.

[0005] However, in the prior art, after long-term use, the filter elements of some devices will intercept a large amount of impurities, resulting in a decrease in filtration efficiency or even blockage. If the filter cannot be disassembled, it is difficult to access and replace these aged or failed filter elements, causing the filtration effect to continue to deteriorate and unable to meet the purity requirements of the liquid in the tank. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings of the prior art and provide a tank bottom filter, so as to facilitate maintenance and replacement, thereby solving the problem of pump cavitation caused by insufficient flow at the pump inlet angle valve after the accumulation of block materials at the tank bottom.

[0007] In order to achieve the above-mentioned purpose, a tank bottom filter is provided, comprising a conical outer shell, the top of which is fixedly connected to a plurality of first outer shells, the interior of the first outer shells is fixedly connected to a first cone, the bottom of the first cone is fixedly connected to a support column, the outside of the support column is slidably connected to a second cone, the interior of the first outer shell is slidably connected to two sliding rods, the exterior of the sliding rods is provided with an elastic component for fixing and capable of storing and releasing energy, the exterior of the sliding rods is fixedly connected to two sliders, and the bottom of the first outer shell is detachably connected to the second outer shell.

[0008] According to the tank bottom filter, the elastic component includes a spring, and the interior of the spring is sleeved on the exterior of the sliding rod.

[0009] According to the tank bottom filter, the top of the conical shell is fixedly connected to a filter assembly for solid-liquid separation, and the bottom of the conical shell is fixedly connected to a second filter screen.

[0010] According to the tank bottom filter, the filter assembly includes a first filter screen, and the outside of the first filter screen is fixedly connected to the inside of the conical shell.

[0011] According to the tank bottom filter, a first water outlet is provided at the bottom of the conical shell, and a detachable through-tube is provided at the bottom of the conical shell.

[0012] According to the tank bottom filter, a second water outlet is provided inside the through pipe, and a third filter screen is fixedly connected to the bottom of the through pipe.

[0013] According to the tank bottom filter, the outer sleeve of the through pipe is provided with a fixing assembly for a fixing mechanism, and the top of the through pipe is fixedly connected to the bottom of the second shell.

[0014] According to the tank bottom filter, the fixing assembly includes a collar, and the interior of the collar is fixedly connected to the exterior of the through pipe.

[0015] Beneficial effects:

[0016] 1. A disassembly mechanism is provided at the bottom of the conical shell. When the first shell is pressed, the two sliding rods inside slide the slider on the surface of the second cone. Because the second cone slides on the support column 11, the slider can slide along the second cone surface to the first cone surface, thereby realizing disassembly, which is more convenient for maintenance and replacement.

[0017] 2. Fix the device to the bottom of the tank and set a collar on the outer wall of the through pipe. In order to prevent the block materials at the bottom of the tank from entering the pump and causing damage to the pump, two filters are set inside the conical shell. The material enters the conical shell along the first filter, passes through the second filter for secondary filtration, and then flows into the through pipe along the first water outlet and is filtered through the third filter. This solves the problem of insufficient flow at the pump inlet angle valve causing pump cavitation after the block materials at the bottom of the tank accumulate.

[0026] This section will describe in detail the specific embodiments of the present invention. The preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present invention, but it cannot be understood as a limitation on the scope of protection of the present invention.

[0027] Reference Figures 1-4 , an embodiment of the present invention is a tank bottom filter, which includes a conical shell 1, which protects the internal electronic components, mechanical parts or other sensitive components from external physical damage, dust, moisture and other environmental factors. The top of the conical shell 1 is fixedly connected to multiple first shells 9, the inside of the first shell 9 is fixedly connected to a first cone 10, and the bottom of the first cone 10 is fixedly connected to a support column 11, which provides additional strength and stability. The outside of the support column 11 is slidably connected to a second cone 12, and the inside of the first shell 9 is slidably connected to two sliding rods 14, which can withstand and transmit force, so that the mechanical equipment can achieve the required linear motion or force conversion. The outer sleeve of the sliding rod 14 is provided with an elastic component for fixing and storing and releasing energy. The outer side of the sliding rod 14 is fixedly connected to two sliders 16, which provide linear motion or cycloidal motion in mechanical movement, and can withstand load and reduce friction. The bottom of the first shell 9 is detachably connected to the second shell 13.

[0028] The elastic component includes a spring 15, which can store energy and release it during the disassembly process, which helps to reduce the external force required for disassembly and can control the disassembly speed to avoid damage caused by sudden release. The inner part of the spring 15 is sleeved on the outside of the sliding rod 14.

[0029] The top of the conical housing 1 is fixedly connected to a filter assembly for solid-liquid separation, and the bottom of the conical housing 1 is fixedly connected to a second filter screen 4, which can separate solid particles, impurities or pollutants in liquid or gas to maintain the purity of the fluid.

[0030] The filter assembly includes a first filter screen 2 , the exterior of which is fixedly connected to the interior of the conical housing 1 .

[0031] A first water outlet 5 is provided at the bottom of the conical housing 1 for controlling the flow rate and speed of water flow to ensure that water can flow in a predetermined manner. A detachable through-tube 3 is provided at the bottom of the conical housing 1 .

[0032] A second water outlet 8 is provided inside the through pipe 3 , and a third filter screen 7 is fixedly connected to the bottom of the through pipe 3 .

[0033] The outer portion of the through pipe 3 is sleeved with a fixing assembly for fixing the mechanism, and the top of the through pipe 3 is fixedly connected to the bottom of the second shell 13 .

[0034] The fixing assembly includes a collar 6 , the interior of which is fixedly connected to the exterior of the through pipe 3 .

[0035] Working principle: The device is fixed to the bottom of the tank, and a disassembly mechanism is set at the bottom of the conical shell 1. The first shell 9 can be pressed so that the two sliding rods 14 inside slide the slider 16 on the surface of the second cone 12. Because the second cone 12 slides on the support column 11, the slider 16 can slide along the surface of the second cone 12 to the surface of the first cone, thereby realizing disassembly. On the contrary, when the sliding rod 14 drives the external fixed slider 16 to slide on the surface of the first cone 10 inside the first shell 9, and the elastic action of the spring 15 makes the slider 16 fall on the support column 111 for fixation, and then it is pulled out together with the top first cone 10 and the first shell 9 for fixation. This is for better convenience of maintenance and replacement.

[0036] A collar 6 is provided on the outer wall of the through pipe 3. In order to prevent the block material at the bottom of the tank from entering the pump and causing damage to the pump, a first filter screen 2 and a second filter screen 4 are provided inside the conical shell 1. The material enters the conical shell 1 along the first filter screen 2, is filtered twice through the second filter screen 4, and then flows into the through pipe 3 along the first water outlet 5, and is filtered through the third filter screen 7. This solves the problem of insufficient flow at the pump inlet angle valve causing pump cavitation after the block material at the bottom of the tank accumulates.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
