Description

Technical Field

[0001] The utility model belongs to the field of tar water filtering devices, in particular to an arc-shaped tar water filtering net. Background Art

[0002] Coke water usually refers to coking wastewater, which is the wastewater generated by the coking plant during the coking and gas production process. This wastewater contains a large amount of harmful substances, has a strong stench and toxicity, and is extremely harmful to the environment and human health. The treatment of coke water usually adds an appropriate amount of coagulant to make the suspended matter and colloidal particles condense into larger clusters, and then remove the clusters and larger particles through filtration before subsequent adsorption and other work. In the process of filtering coke water, a filter is usually used for filtration. The grid of the commonly used filter is designed with parallel surfaces, which filters larger clusters and particles on one side of the filter, while clusters and particles of similar size to the filter are easily stuck in the filter, causing the filter to be blocked, affecting the flow rate of coke water and reducing the filtration efficiency. Therefore, in the process of filtering coke water, the filter needs to be frequently cleaned and unblocked. In the case of severe blockage, the coke water filtration work must be stopped to replace the filter, which greatly delays the work progress. Utility Model Content

[0003] The utility model aims to provide an arc-shaped tar water filter to solve the problem that the mesh of the commonly used filter is designed as a parallel surface, and larger clusters and particles are filtered on one side of the filter, while clusters and particles with a size similar to the size of the filter are easily stuck in the filter, causing the filter to be blocked, affecting the flow rate of the tar water and reducing the filtering efficiency. Therefore, during the current tar water filtering process, the filter screen needs to be frequently cleaned and unblocked. In the case of serious blockage, the tar water filtering work must be stopped to replace the filter, which greatly delays the work progress. Technical problem.

[0004] In order to achieve the above purpose, the specific technical scheme of the arc-shaped coke water filter of the utility model is as follows:

[0005] The arc-shaped tar water filter comprises a base; the base is arranged in a groove shape; a filter is arranged above the base; the filter comprises a plurality of parallel supporting banners and a plurality of filter banners arranged perpendicularly relative to the supporting banners; the supporting banners are arranged in an arc shape with the middle part arched upward and both ends downward; the filter banners are fixedly mounted on the upper side of the supporting banners; the filter banners comprise a supporting end close to the supporting banner and a contact end away from the supporting banner; the width of the supporting end is smaller than the width of the contact end.

[0006] Furthermore, both sides of the base are connected to the filter screen via a plurality of fixing bolts.

[0007] Furthermore, the plurality of filtering banners are arranged in parallel.

[0008] Furthermore, the ratio of the width of the support end to the width of the support end is between 0.3 and 0.5.

[0009] Furthermore, a filter port is formed between two adjacent filter strips; the lower width of the filter port is wider than the upper width.

[0010] The utility model has the following advantages: a filter screen is arranged on the base, including an arc-shaped supporting strip, which cooperates with the filtering strip arranged on the supporting strip to filter the clusters and particles in the coke water, the filter screen blocks the clusters and particles in the coke water, the clusters and particles are impacted by the arc-shaped filter screen and the subsequent flowing coke water on the upper side of the filter screen, the clusters and particles flow to the two sides of the filter screen, and the clusters and particles are prevented from clogging the filter screen, blocking the subsequent flow speed of the coke water, and affecting the overall filtering efficiency; by arranging the filtering strip with a supporting end width smaller than the contact end width, a filter port with an outer side smaller than an inner side is formed between adjacent filter strips, the filter screen effectively filters out larger clusters and particles, and the smaller clusters and particles that pass through can pass through the filter port smoothly, avoiding the clusters and particles from being stuck in the filter port, preventing the filter screen from being stuck, reducing the frequent cleaning and dredging of the filter screen, and increasing the efficiency of the filtering work.

[0016] In order to better understand the purpose, structure and function of the utility model, the arc-shaped coke water filter screen of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0017] like Figure 1-4As shown, the utility model arc-shaped tar water filter comprises a base 1; the base 1 is arranged in a groove shape; a filter screen 2 is arranged above the base 1; the two sides of the base 1 are connected to the filter screen 2 by multiple fixing bolts 7, and the filter screen 2 comprises multiple parallel supporting banners 3 and multiple filtering banners 4 arranged perpendicularly relative to the supporting banners 3; the supporting banners 3 are arranged in an arc shape with the middle part arched upward and both ends downward; the filtering banners 4 are fixedly mounted on the upper side of the supporting banners 3; the multiple filtering banners 4 are arranged in parallel, and the filtering banners 4 include a supporting end 5 close to the supporting banner 3 and a contact end 6 away from the supporting banner 3; the width of the supporting end 5 is smaller than the width of the contact end 6, and the ratio of the width of the supporting end 5 to the width of the supporting end 5 is between 0.3 and 0.5.

[0018] Combination Figure 1-4 As shown, during use, the tar water added with coagulant entering the base 1 is filtered through the filter screen 2, and the arc-shaped support banner 3 cooperates with the filter banner 4 set on the support banner 3 to form an effective filtering effect, and the clusters and particulate matter in the tar water are filtered. The filter banner 4 of the filter screen 2 blocks the clusters and particulate matter in the tar water, and the clusters and particulate matter are impacted by the subsequent flowing tar water on the upper side of the filter screen 2 and are pushed by the arc provided by the arc-shaped filter screen 2, so as to prevent the clusters and particulate matter from clogging the filter screen 2, blocking the subsequent flow speed of the tar water, and affecting the overall filtration efficiency.

[0019] A filter port 8 is formed between two adjacent filter strips 4; the lower side width of the filter port 8 is wider than the upper side width, and the support end 5 width is smaller than the contact end 6 width of the filter strip 4, so that a filter port 8 with an outer side smaller than an inner side is formed between adjacent filter strips 4, and the filter screen 2 effectively filters out larger clusters and particulate matter, while the smaller clusters and particulate matter that pass through can smoothly pass through the filter port 8, avoiding clusters and particulate matter from being stuck in the filter port 8, preventing the filter screen 2 from being blocked, reducing the frequent cleaning and dredging of the filter screen 2, and increasing the efficiency of the filtering work.
