Description

Technical Field

[0001] This utility model relates to the field of pollutant collection technology, specifically to a pollutant particle collection device in a factory environment. Background Technology

[0002] Factory environments typically utilize solid or liquid chemical raw materials, generating waste liquids during chemical production. These waste liquids often contain sparingly soluble or insoluble solid particles. To reduce the pollution caused by these solid particles, it is usually necessary to filter them out of the waste liquid and then place them in the reaction solution for separate purification, thereby reducing the amount of reaction solution used.

[0003] In existing technologies, filter cartridges with hydrophobic holes are typically used to hold waste liquid, allowing the waste liquid to flow out through the holes while solid particles are trapped and retained inside the filter cartridge, thus achieving the purpose of collecting solid particles. However, during the filtration process, solid particles can clog the hydrophobic holes, reducing the efficiency of the filter cartridge when it is used for subsequent filtration operations. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a pollutant particle collection device in a factory environment, so as to solve the problem that solid particles clog the hydrophobic pores when the filter cartridge is performing filtration, which reduces the working efficiency when the filter cartridge performs filtration again.

[0005] This utility model is achieved through the following technical solution:

[0006] A pollutant particle collection device for a factory environment includes a filter cartridge with a hollow structure and an open top. The filter cartridge has drainage holes on its side wall. A scraper is provided inside the filter cartridge, and the side of the scraper is in contact with the inner side of the filter cartridge. The scraper and the filter cartridge slide in axial direction.

[0007] Furthermore, the hydrophobic pores have chamfered edges at one end of the outer side of the filter cartridge.

[0008] Furthermore, the water-repellent holes are provided in multiple groups and are evenly distributed along the axial direction of the filter cartridge, and any group of the water-repellent holes is evenly distributed along the circumference of the filter cartridge.

[0009] Furthermore, a compression spring is provided below the scraper. One end of the compression spring is fixedly connected to the bottom surface of the filter cartridge, and the other end is fixedly connected to the bottom surface of the scraper. When the compression spring is in its naturally extended state, the height of the top surface of the scraper is lower than the height of the opening on the top surface of the filter cartridge.

[0010] Furthermore, the top surface of the scraper is concave with its edges sloping downwards towards the center.

[0011] Furthermore, the top surface of the scraper is provided with multiple water seepage holes that penetrate the scraper.

[0012] Furthermore, a push rod is provided above the scraper, one end of which is fixedly connected to the top surface of the scraper, and the other end extends toward the opening of the filter cartridge and protrudes out of the opening of the filter cartridge.

[0013] Furthermore, the filter cartridge is fitted with a collection cylinder with a hollow structure and an open top. The filter cartridge and the collection cylinder are fixedly connected, and there is a gap between the outer side of the filter cartridge and the inner side of the collection cylinder.

[0014] Furthermore, a support rod is provided below the filter cartridge. One end of the support rod is fixedly connected to the bottom surface of the filter cartridge, and the other end extends axially toward the filter cartridge and is fixedly connected to the bottom surface inside the collection cylinder.

[0015] Furthermore, a blind hole is provided on the bottom surface of the collection cylinder, and the end of the support rod facing away from the filter cylinder is inserted into the blind hole and tightly connected.

[0016] The beneficial effects of this utility model are as follows:

[0017] The pollutant particle collection device in this factory environment uses a scraper installed inside the filter cartridge, with the side of the scraper in contact with the inner side of the filter cartridge. As the scraper slides inside the filter cartridge, it scrapes the inner side of the filter cartridge, pushing the solid particles adhering to the water inlet end of the drainage holes to move, reducing the probability of clogging the drainage holes, facilitating the filter cartridge to perform filtration again, and keeping the filter cartridge at a high working efficiency.

[0029] Please see Figure 1-4 This utility model provides a technical solution: a pollutant particle collection device in a factory environment, including a filter cylinder 1 with a hollow structure and an open top, a water-draining hole 11 on the side wall of the filter cylinder 1, a scraper 2 inside the filter cylinder 1, the side of the scraper 2 being in contact with the inner side of the filter cylinder 1, and the scraper 2 and the filter cylinder 1 slidingly engaging axially.

[0030] By setting a scraper 2 inside the filter cartridge 1 and having the side of the scraper 2 attached to the inner side of the filter cartridge 1, the scraper 2 scrapes the inner side of the filter cartridge 1 when it slides inside the filter cartridge 1, pushing the solid particles adhering to the water inlet end of the pores 11 to move, reducing the probability of the pores 11 becoming clogged, facilitating the filter cartridge 1 to perform filtration again, and enabling the filter cartridge 1 to maintain high working efficiency.

[0031] When in use, connect the open end of the filter cartridge 1 to the external wastewater discharge pipe, and keep the filter cartridge 1 with the opening facing upward. The wastewater is directly discharged into the filter cartridge 1 through the external pipe, and the solid particles in the wastewater are captured by the filter cartridge 1.

[0032] In this embodiment: the hydrophobic hole 11 has a chamfered edge at one end of the outer side of the filter cartridge 1.

[0033] The edge of the opening of the drainage hole 11 at one end of the outer side of the filter cylinder 1 is beveled, so that the drainage hole 11 is a conical hole that expands from the inner end of the filter cylinder 1 to the outer end of the filter cylinder 1. Since the drainage hole 11 is the water inlet at the inner end of the filter cylinder 1 and the water outlet at the outer end of the filter cylinder 1, that is, the diameter of the water inlet is smaller than the diameter of the water outlet, when solid particles with a size smaller than the diameter of the water inlet enter the drainage hole 11, they can be smoothly discharged from the drainage hole 11, reducing the probability of the drainage hole 11 being blocked.

[0034] In this embodiment: multiple hydrophobic holes 11 are provided and are evenly distributed in multiple groups along the axial direction of the filter cylinder 1, and any group of hydrophobic holes 11 is evenly distributed along the circumferential direction of the filter cylinder 1.

[0035] By setting multiple drainage holes 11, multiple wastewater outflow channels are provided inside the filter cartridge 1. When one or more drainage holes 11 are blocked by solid particles, the remaining drainage holes 11 can continue to drain water, allowing the filter cartridge 1 to continuously perform filtration. At the same time, the height of the scraper 2 inside the filter cartridge 1 can be adjusted to change the number of drainage holes 11 above the scraper 2, thereby adjusting the filtration efficiency of the filter cartridge 1.

[0036] In this embodiment: A compression spring 3 is provided below the scraper 2. One end of the compression spring 3 is fixedly connected to the bottom surface of the filter cylinder 1, and the other end is fixedly connected to the bottom surface of the scraper 2. When the compression spring 3 is in its naturally extended state, the height of the top surface of the scraper 2 is lower than the height of the opening on the top surface of the filter cylinder 1.

[0037] Compression spring 3 is used to provide flexible support for scraper 2. When waste liquid is injected into filter cartridge 1, the weight on scraper 2 increases, pushing scraper 2 to move downward. Compression spring 3 is squeezed and contracted to store energy, increasing the number of exposed drainage holes 11 above scraper 2, and drainage is performed through these drainage holes 11.

[0038] When the volume of waste liquid flowing into filter cartridge 1 increases to a greater than the volume of waste liquid flowing out of filter cartridge 1 per unit time, the waste liquid contained in filter cartridge 1 increases, the weight increases, scraper 2 continues to move downward, the deformation of compression spring 3 increases, and the number of exposed hydrophobic holes 11 above scraper 2 further increases, so as to automatically increase the number of wastewater outflow channels in filter cartridge 1 and accelerate the discharge of wastewater in filter cartridge 1.

[0039] When the volume of waste liquid flowing into filter cartridge 1 decreases to less than the volume of waste liquid flowing out of filter cartridge 1 per unit time, the waste liquid contained in filter cartridge 1 decreases, the weight decreases, the compression spring 3 releases energy and extends, pushing the scraper 2 to move upward, scraping and separating the solid particles adhering to the inner side of filter cartridge 1, reducing the probability of the hydrophobic holes 11 being blocked, and pushing the solid particles to move upward.

[0040] When the wastewater in the filter cartridge 1 is completely discharged, the compression spring 3 releases energy and extends freely, pushing the scraper 2 to move upward and lifting the filtered solid particles close to the opening of the filter cartridge 1 so that the solid particles can be removed from the filter cartridge 1.

[0041] That is, when the volume of waste liquid flowing into filter cartridge 1 per unit time is greater than the volume of waste liquid flowing out of filter cartridge 1, the number of wastewater outflow channels in filter cartridge 1 is automatically increased to accelerate the discharge of water from filter cartridge 1; when the volume of waste liquid flowing into filter cartridge 1 per unit time is greater than the volume of waste liquid flowing out of filter cartridge 1, scraper 2 automatically scrapes and separates solid particles adhering to the inner side of filter cartridge 1, reducing the probability of the hydrophobic holes 11 being blocked; when the wastewater in filter cartridge 1 is completely discharged, scraper 2 automatically lifts and raises the filtered solid particles close to the opening of filter cartridge 1 so that the solid particles can be removed from filter cartridge 1.

[0042] In this embodiment, the top surface of the scraper 2 is concave with its edges sloping downwards towards the center.

[0043] By setting the top surface of the scraper 2 to be concave in the middle, the solid particles captured in the filter cartridge 1 are drawn from the edge to the center along the inclined surface on the scraper 2 under the action of gravity, so that the solid particles are away from the water-draining holes 11 on the side wall of the filter cartridge 1, further reducing the probability of the water-draining holes 11 being blocked.

[0044] In this embodiment, a plurality of water seepage holes 21 penetrating the scraper 2 are provided on the top surface of the scraper 2.

[0045] By setting the seepage hole 21, the outflow channel of wastewater above the scraper 2 inside the filter cartridge 1 is increased, which promotes the discharge of wastewater and improves the filtration efficiency. The diameter of the seepage hole 21 is set to be smaller than the diameter of the inlet end of the drainage hole 11, so that solid particles that pass through the seepage hole 21 and enter the filter cartridge 1 below the scraper 2 can pass smoothly through the drainage hole 11 below the scraper 2, reducing the probability of the drainage hole 11 below the scraper 2 being blocked.

[0046] In this embodiment: A push rod 22 is provided above the scraper 2. One end of the push rod 22 is fixedly connected to the top surface of the scraper 2, and the other end extends toward the opening of the filter cartridge 1 and protrudes out of the opening of the filter cartridge 1.

[0047] When it is necessary to clean the inner wall of the filter cartridge 1, hold the push rod 22 and apply a thrust to the push rod 22 in the axial direction of the filter cartridge 1, so that the scraper 2 moves relative to the filter cartridge 1. The inner side of the filter cartridge 1 is scraped and cleaned by manually operating the scraper 2. The operation is simple and convenient.

[0048] In this embodiment: the filter cartridge 1 is fitted with a collection cylinder 4 with a hollow structure and an open top. The filter cartridge 1 and the collection cylinder 4 are fixedly connected, and there is a gap between the outer side of the filter cartridge 1 and the inner side of the collection cylinder 4.

[0049] The collection cylinder 4 is used to hold the waste liquid after the solid particles have been filtered. By setting a gap between the outer side of the filter cylinder 1 and the inner side of the collection cylinder 4, the wastewater flowing out of the drainage holes 11 can pass through the gap and flow into the bottom of the collection cylinder 4, so that the filter cylinder 1 can perform the filtration work smoothly.

[0050] In this embodiment: a support rod 12 is provided below the filter cylinder 1. One end of the support rod 12 is fixedly connected to the bottom surface of the filter cylinder 1, and the other end extends axially toward the filter cylinder 1 and is fixedly connected to the bottom surface of the collection cylinder 4.

[0051] The support rod 12 is used to support the filter cartridge 1, so that the filter cartridge 1 is suspended in the collection cylinder 4, keeping the filter cartridge 1 away from the wastewater at the bottom of the collection cylinder 4, so that the filter cartridge 1 can continue to perform filtration smoothly.

[0052] In this embodiment: a blind hole 41 is provided on the bottom surface of the collection cylinder 4, and the end of the support rod 12 facing away from the filter cylinder 1 is inserted into the blind hole 41 and tightly connected.

[0053] By tightly inserting the support rod 12 into the blind hole 41, the support rod 12 can be disassembled and removed from the blind hole 41, allowing the filter cartridge 1 to be removed from the collection cylinder 4. This enables the solid particles captured in the filter cartridge 1 to be quickly removed by tilting, achieving the purpose of rapid transfer of solid particles. After the filter cartridge 1 is removed from the collection cylinder 4, the waste liquid contained in the collection cylinder 4 can be poured out for purification treatment. At the same time, after the filter cartridge 1 is disassembled and removed from the collection cylinder 4, it is convenient to clean the collection cylinder 4 and the filter cartridge 1, as well as replace the filter cartridge 1 with one of different pore diameters of the hydrophobic holes 11.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
